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.

What is food grade silicone? What are the advantages? Food-grade silicone is environmentally friendly, non-toxic, food-grade silicone, food-grade silicone is widely used in life, such as silicone kitchenware, silicone adult products.   Food grade silicone with its soft and elastic feel, rich and diverse colors, gradually replacing steel, stainless steel, plastic and other materials. There are two main categories of food-grade silicone products: pure silicone products and silica-containing products.   Food-grade silicone has the following advantages:   Food grade silicone is rich in color. Food grade silica gel raw material is transparent, its color can be adjusted by food grade color masterbatch, food grade color masterbatch is diverse, so the color of food grade silica gel is also rich and colorful.   Food grade silicone is soft and comfortable, elastic, giving a comfortable touch and will not deform.   Food grade silicone has a wide temperature range and can be used at -40 degrees to 280 degrees.   Food grade silicone has a long service life. Food grade silicone can be used for a long time without yellowing, aging resistance and degradation.   Food grade silicone is easy to clean.

At present, the food grade silicone product levels mainly involved in the market are mainly divided into drug grade silicone and food grade silicone, but it needs to be certified by the State Food and Drug Administration. Infant and toddler products on the market in China generally follow three national standards: China, the United States, and Europe. Experts suggest that when purchasing, you need to know what national standards the product is implemented, and whether it is certified by the National Food and Drug Administration or a third-party testing agency to ensure that it is genuine.

What is the difference between silicone products and rubber products? Silicone products and rubber products play an important role in our daily life, and they each have unique characteristics and uses. Although both are elastic materials, there are obvious differences in composition, properties, uses and production processes.   First of all, from the perspective of composition, silicone products are mainly made of porous solid polymer materials obtained after drying and dehydration of silicone gel, and its main component is silicon dioxide. Rubber products are made of natural rubber or synthetic rubber through processing, and its main component is rubber hydrocarbon. This difference in composition makes the two different in physical and chemical properties.   Secondly, silicone products and rubber products have obvious differences in physical properties. Silica gel has better stability, weather resistance and high and low temperature resistance, and can be used for a long time in the range of -60 ° C to 250 ° C. In addition, silica gel also has excellent electrical insulation properties and chemical stability, and is not easily affected by the environment. Rubber has good elasticity and wear resistance, but in high or low temperature environments, its performance may be affected.   In terms of use, silicone products are widely used in medical treatment, baby bottles, pacifiers, high voltage wire skin and other fields because of its excellent performance. For example, medical silicone products are non-toxic and tasteless, chemically stable, and have good histocompatibility with the human body, so they are widely used in the production of medical devices and implants. Rubber products are widely used in tires, seals, soles and other fields because of their good elasticity and wear resistance.   Finally, from the production process point of view, there are also differences in the manufacturing process of silicone products and rubber products. The production process of silicone products usually includes raw material mixing, molding, curing, post-treatment and other steps, of which the curing process can be achieved by vulcanization or hot pressing. The production process of rubber products may involve more processes, such as rubber mixing, calendering, molding, vulcanization, etc.   In summary, there are significant differences between silicone products and rubber products in terms of composition, properties, uses and production processes. Understanding these differences helps us to better select and use these two materials to meet the needs of different fields.

What are the molding methods of silicone products? Silicone products are widely used in various fields because of their excellent physical properties, chemical properties, etc. In the process of manufacturing silicone products, molding is a crucial step.   1. Injection molding Injection molding is a more common method of molding silicone products. The method is to inject liquid silica gel into the heated silica gel material, and then form the desired shape of silica gel product in the mold through high temperature and high pressure processing. Compared with other forming methods, injection molding method has high accuracy, high material utilization rate, and can be automated production.   2. Calendering forming method The calender forming method is to calender silica gel into a sheet shape, and then form a product by die-cutting. Its production process is simple, low cost, suitable for the production of some simple silica gel products, such as silica gel sheet and silica gel strip.   3. Molding method The molding method is to press the silicone material into the mold, and use the high temperature and high pressure processing method to make the silicone material formed. The method is suitable for the production of medium-sized silicone products, such as silicone sealing rings, silicone pipes, etc.   4. Electrostatic spraying forming method Electrostatic spraying molding method is to spray silicone evenly on the surface of the appliance and cure naturally in the air, and can be released after silicification to get the desired silicone products. The method has high production efficiency and is suitable for mass production of silica gel products.

It is said that the silicone material has a big disadvantage is that the toughness is not good, and it is careful to encounter sharp sharps, and with the industry application of all walks of life, the demand for silicone gaskets, silicone flakes and other thin materials is gradually increasing, so the relatively thin product tear resistance has become the trouble of many friends. The silicone gasket purchased is easy to tear and easy to be not durable enough, etc., so combined with various reasons, it can still be identified as caused by several factors!   Tear is the core performance of silicone products, so the tear resistance from the addition of raw material silicone resin in the baking curing process has a great reason! For example, room temperature curing for 24 hours, 130 degrees baking curing difference is relatively large, so the most fundamental reason is the baking time problem, time and temperature do not conflict, but to achieve the same condition of the effect of common, so high temperature baking curing and room temperature curing for a long time will have a great difference, so the raw materials occupy most of the factors! Secondly, silicone products manufacturers in the production vulcanization process, the reason for the tear strength or the production process, the general normal temperature, the normal time can avoid the phenomenon of easy tearing, and in the abnormal processing production time and temperature may cause the phenomenon of poor tearing degree! For example, the staff want to increase the output, the temperature of the machine to reduce the time of vulcanization this method is not feasible for thinner, smaller products, first of all, easy to cause the product is too brittle, poor tear resistance, followed by the mold too early prone to the phenomenon of immature products, so the feasible method is normal processing when adjusted, don't have a lucky mind, easy to bad things!
