Why choose silicone products? In the increasingly severe environmental problems of the present, the search for environmental protection and sustainable development of materials has become a global common topic. Silicone products, as a new environmental protection material, with its excellent performance and friendly attitude to the environment, is becoming a strong support to promote sustainable development.   1. Environmentally friendly materials for silicone products Silicone is a substance derived from natural silicon ore, after processing, you can make a variety of silicone products. This material produces almost no pollution during the production process and can be recycled, in line with the concept of environmental protection and sustainable development.   2. Advantages of silicone products High temperature resistance: silicone products can withstand high temperatures of up to 230 ° C, suitable for a variety of cooking and baking environments. Low temperature resistance: at very low temperatures, silica gel can still maintain good elasticity and flexibility. Electrical insulation: Silica gel has good electrical insulation properties and is widely used in the manufacture of electronic components.   3. Advantages of silicone products Environmental protection and non-toxic: silicone material does not contain harmful substances, friendly to the human body and the environment. Durability: Silicone products have a long service life, are not easy to damage, and reduce the waste of resources. Degradability: Some silicone products can be degraded under specific conditions to reduce environmental pollution.   4. Sustainable development of silicone products The production and use of silicone products is in line with the principle of sustainable development and helps to reduce resource consumption and environmental pollution.

Silicone products are stain resistant, silicone products play an important role in our daily life, its wide range of applications include kitchenware, baby products, electronic products accessories and so on. However, for consumers, whether silicone products are stain resistant is an important consideration. So, are silicone products stain resistant?   First of all, we need to understand the basic characteristics of silicone products. Silica gel is a kind of highly active adsorption material, which has the characteristics of non-toxic, tasteless, chemical stability, high temperature resistance and so on. These characteristics make silicone products less susceptible to chemical erosion in daily use, thereby increasing their ability to resist stains to a certain extent. ​​​However, the stain resistance of silicone products is not absolute. In the actual use process, silicone products may come into contact with various stains, such as food residue, grease, pigments, etc. These stains may leave traces on the surface of the silicone, especially if it is not cleaned for a long time. Therefore, for the stain resistance of silicone products, we need to have a rational understanding. ​​​In order to improve the stain resistance of silicone products, manufacturers usually use some special processes and materials. For example, the surface of some silicone products will be covered with a protective film to increase its anti-fouling ability. In addition, when using silicone products, consumers also need to pay attention to keeping them clean. Regular cleaning of silicone products to avoid stains attached to the surface for a long time can effectively extend its service life. ​​​In summary, silicone products have stain resistance to a certain extent, but are not completely immune to stains. When using silicone products, consumers should pay attention to keeping them clean, and choose the appropriate cleaning method according to actual needs. At the same time, when purchasing silicone products, you can also pay attention to the stain resistance of the product and choose products with better stain resistance.   Regardless of the stain resistance of silicone products, it is very important to maintain the cleanliness and hygiene of the product. Only the correct use and maintenance of silicone products can ensure that they maintain good performance and appearance during use.

The frequency of use of silicone products in life is very high, many things in our daily life may be made of silicone, sometimes when we usually use silicone products, we will find that the surface or inside of silicone products will produce bubbles, for the reasons of silicone products have bubbles, why silicone products will have bubbles and how to deal with the problem of silicone products.   1. How to solve the bubbles produced in the production process of silicone products ​In the case of silicone has not been cured with a vacuum machine to bubble processing, can be a good solution to the problem, if there is no vacuum machine can also use defoamer, defoamer defoamer is not very thorough, if these two things are not available, you can adjust the curing time of silicone as long as possible, and then put there, silicone products will slowly discharge bubbles.   2. Causes and treatment of bubbles in thermal silicone sheet ​(1) The vulcanization temperature is too low or the vulcanization temperature is too high is one of the main reasons for the foaming of thermal conductive silica gel sheet. Vulcanization temperature is an important parameter of silicone molding, usually silicone products are set at 160~200 degrees Celsius, but sometimes because the operation time outside the mold is too long or other reasons so that the mold has not opened the vulcanization machine for a long time, resulting in the temperature of the silicone molding mold is low and the vulcanization temperature of the silicone, at this time it will cause the product bubble after the molding of the thermal conductive silicone sheet. For this, we only need to increase the molding temperature, or open the empty mold into the machine to heat up for a period of time in operation to solve the problem. If the vulcanization temperature is too high, the molding temperature is too high, which will also cause thermal conductive silica gel sheet bubbles. Why is that? When the molding temperature is too high, the surface of the silicone material has begun to form in the process of clamping pressure, at this time the air has been trapped inside and it is difficult to discharge, so it will cause thermal conductive silicone sheet forming bubbles. For this reason, just reduce the molding temperature appropriately. ​(2) The reason for the bubbles of silicone products is the lack of exhaust gas, silicone raw materials placed in the molding mold, at the moment of closing the mold will bring a lot of air, and the air is impossible to be integrated with silicone raw materials, if the air is not discharged, it will cause bubbles on the surface of silicone button molding. ​(3) The structure of the mold is unreasonable, and the design of the silicone molding mold is not reasonable, which will also cause bubbles in the silicone molding, such as the arrangement of the product in the mold, the partition way, the mold parting way, the design of the mold size, etc., will cause poor bubbles, but the cost of opening a set of molds is high, and it is not easy to modify. If the silicone molding bubble is caused by the structure of the mold, then it is usually solved from the above mentioned points. (4) The vulcanization time is too short, like the vulcanization temperature, the vulcanization time is also one of the important parameters of the molding of the thermal silicone sheet, and the length of the vulcanization time determines whether the thermal silicone sheet can be completely vulcanized. If the vulcanization time is too short, it will not only cause the thermal conductive silicone sheet to be soft after forming, but also cause bubbles on the surface of the thermal conductive silicone sheet. The occurrence of such defects can properly extend the vulcanization time of silica gel. (5) The production process is also very important: Antioxidant RD is easy to produce bubbles in the mixing operation of the open mill, which is mainly the melting point of antioxidant RD is high and the operating temperature of the open mill is low. Special attention should be paid to the dispersion of zinc oxide when mixing rubber, and its dispersion uniformity will also cause the thermal conductive silicone sheet to bubble, so the rubber mixing process is also a very important link. (6) The moisture content of raw materials used in the formula and whether the mixing operation and products are sufficiently dried after water cooling are mainly caused by the volatilization of water when sulfur is added.   3. Reasons and treatment methods for bubbles after curing of potting silica gel ​First, the bubbles brought in during the mixing or filling process are not eliminated. During the mixing process, due to the large viscosity of the glue or the wrong mixing method, it is easy to bring air into the glue, and if the viscosity of the glue is large, the bubbles are more difficult to eliminate. If the viscosity of the glue is small and the glue cures slowly, the bubbles will slowly rise to the surface and automatically eliminate. Second, the bubbles produced during the curing process. There are several reasons for bubbles in the curing process: the curing speed is too fast, the heat dissipation temperature is high, the shrinkage rate of glue curing is large, and the amount of solvent and plasticizer added in the glue is too easy to produce bubbles in the curing process. Another is that the formula of silica gel contains a small amount of volatile impurities, which are vaporized to form bubbles when heated and cured. In view of the causes of silica gel bubbles, there are several methods to avoid or remove bubbles for reference. For the first reason, vacuum or centrifugation can be used to solve the problem. You can also take the method of standing for a period of time (30 minutes -2 hours) and wait for the bubble to float up by itself. If there is no vacuum machine, stir in the clockwise direction for 2 to 3 minutes, and place the glue for 5 to 20 minutes after stirring, but this method is only for those glue with thinner viscosity, if the glue is very thick, the bubbles remaining in it are not easy to rise and discharge. For the second reason, the bubbles caused by volatile impurities in the silicone formula can be baked at low temperature, so that these impurities evaporate first, and then increase the temperature curing, so that there are no bubbles. To solve those problems in the curing process, it is necessary to adjust the overall formula of the glue. ​​​ 4. The reason why there are small bubbles on the surface of silicone products In fact, we can find that after the rubber surface is dry, break the bulging rubber, and you can see that it is empty, indicating that this is a small bubble. If you start in just a few minutes, it should be too high water, but if your product bubbles are sporadic, it means that the water is not too high, and if the rubber water is too high, the application period of your product should be shortened! I still doubt whether the bubbles in the rubber material are because your A component is too thick and air is stored in it when you put it into the rubber material bucket or your material is mixed unevenly. There are not many opportunities for users to really have this problem, which is occasional, and more than 90% of products have no complaints in this regard. We have also suspected that there is no problem with the user's glue machine caused by the foaming phenomenon. But the user insists that his glue machine is no problem, we can only find the reason on the glue. The A component in the two-component silica gel is vacuumed, and it is also noted when packaging. But the problem of moisture was not taken into account. Do single-component products know that dehydration is very important, do two-component products A component is indeed not seriously dehydrated. I always feel that it is two-component anyway, and A little water in component A will not affect the storage period. Through the above analysis, it seems that component A should also be considered seriously dehydration.

Adhesive foot pad in a variety of products base as a foil buffer, it has been widely used in major industries, belongs to a kind of micro auxiliary accessories, low cost and simple function, but some products have it and it is too redundant, some items do not have it, so with its role and function, many items need to use it to set off the use, The difference is that it has a different process and a different structure.   The function of the rubber foot pad is based on the adhesion of the bottom as a whole plane, at present, our common rubber gaskets are made of a plane with non-slip sungrain texture, and its main process is made of flat gaskets as a whole calendering process or molded sheet molding. This kind of silicone gasket has a wide range of applications, which are used in many seats, wardrobes and electronic and electrical products, so both sides belong to the plane structure under the premise of the plane effect, and can be applied to a variety of flat products for backgluing.   The other is the structural rubber pad, this kind of foot pad must use the oil pressure molding process for production and processing, to make the effect of convex and curved structures to fit, this way is mainly for the processing of special-shaped rubber parts, can be used for customized rubber parts processing in various fields. Flat and shaped adhesive parts need to be fitted, the adhesive way is divided into single-sided adhesive and double-sided adhesive, followed by the adhesive paper is also very important, the current commonly used silicone adhesive paper is divided into TPE adhesive paper and double-sided adhesive paper. Back adhesive paper is also divided into genuine and imitation products, high strength and conventional adhesive, different quality for different products, the current silicone pad is commonly used 3M back adhesive paper, so in different foot pad life above which to consider its adhesive paper and use strength.

Silicone products are widely used in daily life and industrial production because of their excellent elasticity, high temperature resistance, wear resistance and other characteristics. However, the bonding of silicone material is a technical problem, which requires certain methods and skills. The bonding process of silicone products needs to be analyzed in several steps.   Before bonding silicone products, first ensure that the bonding surface is clean and dry. Any oil, dust or moisture may affect the bonding effect. Therefore, it is essential to carefully clean the adhesive surface with alcohol or special cleaners. At the same time, according to the material and use of silicone products, choosing the right adhesive is also the key. In general, silicone adhesives are divided into silicone and inorganic silicon, the specific choice should be based on the nature of silicone products and the use of the environment to determine. In the bonding process, the correct operation steps are also important. First, apply the adhesive evenly on the clean and dry adhesive surface, and pay attention to controlling the amount of adhesive to avoid too much or too little. Then, the adhesive of the two silicone products is aligned and gently pressed to ensure that the adhesive is evenly distributed and the air bubbles are released. During the bonding process, fixtures or weights can be used for fixing to increase the bonding strength.   The bonded silicone products need to be fully cured. Curing times may vary depending on the type and thickness of adhesive. During the curing period, excessive external force or exposure to high temperature environment should be avoided on silicone products, so as not to affect the bonding effect. After curing, the silicone products can be tested to ensure that they achieve the expected bonding strength and durability.   Different brands and types of silicone adhesives may have different performance characteristics and use requirements, so you should carefully read the product manual before use to understand the performance and use of adhesives. Secondly, the bonding process of silicone products should avoid the use of lubricants or cleaners containing silicone oil, because silicone oil will destroy the surface structure of silicone products, affecting the bonding effect. At the same time, for silicone products with special shapes or structures, special bonding processes and skills may be required to ensure bonding quality and stability.   The storage and use conditions of the adhesive are also important factors affecting the bonding effect. Adhesives should be stored in a cool, dry, ventilated place, away from direct sunlight and high temperatures. Before use, the shelf life and appearance quality of the adhesive should be checked to ensure that it has not expired or deteriorated. During use, attention should be paid to keeping the operating environment clean and sanitary to avoid pollution from dust and impurities. In order to improve the bonding quality and stability of silicone products, some auxiliary measures can also be taken. For example, preheating the silicone product before bonding can improve its surface activity and the reaction speed of the adhesive; The use of vacuum equipment to remove bubbles in the bonding process can improve the compactness and uniformity of the bonding surface. Post-treatment of silicone products after curing, such as grinding, polishing, etc., can further improve their appearance quality and durability. The bonding of silicone products is a job that requires mastering certain skills and methods. By choosing the right adhesive, mastering the correct operating steps and precautions, and taking the necessary auxiliary measures, you can ensure the bonding quality and stability of silicone products. At the same time, with the continuous progress of science and technology and the continuous improvement of the performance of silicone materials, I believe that the bonding technology of silicone products will be further developed and improved in the future.

What is the injection process of silicone products, in today's changing science and technology, silicone products because of their unique physical and chemical properties, in medical, electronics, automobiles, daily life and other fields show a wide range of applications. The injection process of silicone products, as an important technology in modern manufacturing, is gradually becoming the mainstream way of production of silicone products with its efficient, accurate and environmental protection characteristics.   1. Injection process of silicone products The injection process of silicone products, in short, is to inject liquid silicone raw materials into the mold through high pressure injection equipment, and form products of the required shape and size after cooling and curing. This process combines the principle of plastic injection molding with the characteristics of silicone materials to achieve efficient and accurate production of silicone products. Compared with the traditional molding, extrusion and other processes, the injection process of silicone products has shown significant advantages in terms of production efficiency, product quality and material utilization.   2. Injection process of silicone products The injection process of silicone products can be roughly divided into four main steps: raw material preparation, injection molding, cooling and curing, stripping and dressing. First of all, the liquid silica gel raw material is mixed evenly according to a certain proportion and preheated to the appropriate temperature to ensure its good fluidity. Subsequently, the preheated silica gel raw material is injected into the pre-designed mold through a high-pressure injection machine. In the mold, the silica gel raw material is quickly cooled and cured to form a product consistent with the shape of the mold. After the product is completely cured, it can be demoulded. Finally, the demoulded products are trimmed and inspected as necessary to ensure that they meet the quality requirements.   3. Advantages of silicone injection process Efficient production: The injection process of silicone products realizes automatic production, which greatly improves the production efficiency. Compared with the traditional process, the injection molding process can significantly shorten the production cycle and reduce the production cost. Precision molding: The injection molding process can precisely control the injection amount and injection pressure of the silicone raw material to ensure the dimensional accuracy and shape stability of the product. At the same time, the accuracy of the mold also directly determines the accuracy of the product, making the manufacturing of silicone products more refined. High material utilization rate: In the injection molding process, the utilization rate of silica gel raw materials is high, which reduces the waste of raw materials. In addition, due to the good fluidity of the silicone raw materials during the injection process, all corners of the mold can be fully filled to avoid defects and defects of the product. Environmental protection and energy saving: silicone injection process does not need to use a lot of energy and water resources in the production process, and produces less waste. At the same time, the silicone material itself is non-toxic and harmless, and meets the requirements of environmental protection.   4. Application of injection process of silicone products Silicone injection technology has been widely used in many fields. In the medical field, silicone products are widely used in the manufacturing of medical devices, artificial organs and other products because of their good biocompatibility and corrosion resistance. In the field of electronics, the insulation, high temperature resistance and weather resistance of silicone products make it an ideal packaging material for electronic components. In addition, in the automotive, daily life and other fields, silicone products also play an important role, such as automotive seals, kitchen supplies and so on.

In Che plastic products processing process, a process with the most troubling is the down side, especially with mould pressing craft products, edge can let a person down to mad. So what are the causes of rough edges?   1. The curing temperature is too high or the curing time is too long Silicone products in the molding process, once the temperature is too high or the vulcanization time is too long, it will cause the product to become numb or brittle after forming, whether it is numb or brittle, it will have a great impact on the disassembly. 2. Vulcanization temperature is too low, vulcanization time is too short silicone products are not fully vulcanized when the elasticity is very strong, so it is not easy to separate the raw edge from the product when removing the edge, so it is generally necessary to use scissors to trim the edge. 3. The mold self-disassembly design is unreasonable, the processing quality is not up to standard or the mold wear time is too long. In the design of the mold, the mold design is unreasonable, and the self-disassembly of the manufacturing mold is not sharp, resulting in difficult to remove the edge after the product is formed. In addition, too many times of mold wear or sandblasting of silicone products will also affect its self-disassembly performance.   4. The molding thickness is too large In the molding process, as long as the size meets the requirements, try to do, scale, material accurate,   5. Silicone raw material problem The rubber chain has problems, the quality of the rubber material is poor, there is insufficient tearing strength, poor toughness, easy to break after forming.

Glass is widely used in our lives, there are many kinds of glass, and its performance and material characteristics are not the same, but the glass needs screen printing in the production process, when the screen printing glass, the glass screen printing material needs how to choose? Let's get to know each other.   1, suitable for printing glass According to the user's requirements, the glass can be cut in regular shape or irregular shape, and then the edge grinding, cleaning, drying and waiting for use. Special attention should be paid to the fact that there should be no water marks on the glass surface.   2, the choice of wire mesh The screen plate for glass printing is the same as the general screen plate, and the glass screen plate uses synthetic fiber screen, stainless steel screen, and natural fiber screen. When printing general color, the above screen can be, generally choose cheap synthetic fiber screen, as gold and silver decoration, you can not choose stainless steel screen, screen specifications generally use 270 ~ 300 mesh.   3, the choice of mesh frame At present, the more regular and deformation of the mesh frame is an aluminum alloy mesh frame, and its size should be larger than the pattern, and the specific size should be the outer edge of the pattern from the mesh frame should be between 70 and 100mm. In addition, the strength of the mesh frame is very important, and the key is that the horizontal rigidity is enough.   4. Stretch the net Choose the mesh and the mesh frame, and combine the two, which is the stretched net. There are many ways to stretch the net, you can use manual, mechanical, pneumatic methods, the current more advanced, can stretch high quality screen is the pneumatic stretching machine. The requirements of the stretched net are uniform tension, the longitude and latitude lines of the net remain vertical, and the adhesive should be firm and not slack.

Silicone products can be disinfected with alcohol, silicone products are widely used in our lives, whether it is kitchen utensils, baby bottles, or medical equipment and adult products, silicone has occupied an important position with its unique advantages. However, for the cleaning and disinfection of silicone products, many people still have some questions, especially about whether alcohol can be used to disinfect silicone products.   First, we need to understand how alcohol disinfecting works. Alcohol has a strong bactericidal effect, it can effectively destroy the cell structure of bacteria and viruses, so as to achieve the purpose of disinfection. For this reason, alcohol is often used as a common disinfectant.   So, can silicone products be disinfected with alcohol? The answer is yes. Silicone has a good tolerance to alcohol, alcohol will not corrode silicone, and will not cause harm to silicone. In fact, some silicone products in the production process, in order to achieve higher hygiene standards, will be treated with high temperature, with alcohol or normal saline disinfection and preservation.   However, although alcohol can effectively sterilize silicone products, there are still some things to pay attention to during use. First, avoid direct contact with alcohol, as alcohol may cause irritation to the mucosa. Secondly, after the use of alcohol disinfection, you should avoid directly touching the silicone products with your hands, or wiping with a towel to prevent bacteria and pathogenic microorganisms from attaching again. In addition, some people may be allergic to alcohol, so when using alcohol disinfection silicone products, you should closely observe the changes in the body, if you feel uncomfortable, you should seek medical attention in time.   In addition to alcohol disinfection, silicone products can also be sterilized by other means. For example, high temperature steam disinfection is a common method for high temperature resistant silicone products. In addition, ultraviolet disinfection is also a chemical-free disinfection method, which is suitable for silicone products with good ultraviolet resistance.

Silicone keys in all kinds of fields of equipment are very common, but different fields of silicone keys are not the same requirements, some to light, and some to waterproof, how to design waterproof silicone keys. Silicone itself is waterproof, in order to silicone keys can play a waterproof role, it is necessary to consider from the key structure design. First of all, the key structure can not have positioning holes, once the positioning hole is designed, when the water flows into the key, it is likely to flow from the gap in the positioning hole into the circuit board. Second, the key also needs to design a waterproof edge, waterproof edge refers to the bottom four periphery of the silicone key, design a silicone waterproof wall higher than the bottom thickness of the key, and then according to the shell, circuit board and keys, design a fixed slot on the edge of the waterproof wall (usually semicircular), the position of the fixed slot needs to have a certain distance from the position of the circuit board.   Significance of silicone button wear test: Silica gel is a kind of highly active adsorption material, which belongs to amorphous substance. The main component of silicone is silica, which is chemically stable and does not burn. Silicone is not only resistant to high temperature but also low temperature, and can be used in a wide temperature range, generally between -40 degrees and 400 degrees. Both chemical properties and physical and mechanical properties change little with temperature. So silica gel is widely used. However, this kind of high-temperature special silicone product material is relatively special in the market is not common, so the cost is relatively high.   Silicone button wear test is good: Mold problem of silicone products. Mold manufacturers tampered with the structure, so that the products produced only have their shape and no performance. Moreover, the mold material is inferior, and the mold is often repaired during use and cannot reach the predetermined production capacity. In strict accordance with customer product drawing mold.
