When users use silicone rubber gaskets, they naturally hope for good quality, but when it comes to their quality, there are also many aspects to consider. Only when it meets various quality requirements can it be a truly high-quality product. So what kind of product is a high-quality gasket? Firstly, it is necessary to ensure that it has good oil resistance during use, as this type of product is generally used in oily environments. If it does not have good oil resistance, its environmental adaptability during use will naturally decrease, and such products are not high-quality brands.   When users use silicone rubber gaskets, they also need to have good temperature adaptability, which can be divided into two aspects: high temperature resistance and low temperature resistance.   If one aspect of the two does not meet the requirements, it is naturally impossible to ensure good quality of the silicone gasket. So when users use this product, they naturally need to pay attention to this aspect. Of course, in order for the product to have this advantage, it is necessary for the manufacturer to use high-quality silicone raw materials, and also to meet the requirements in terms of technical processing.   Any user who uses a silicone gasket product also hopes that it will have a good service life. To make it have a good service life, the product needs to have a good anti-aging advantage. However, the silicone rubber gaskets produced by some manufacturers in the market do not have this advantage. On the one hand, the manufacturers do not use advanced anti-aging materials in production, and on the other hand, the technical treatment in all aspects does not meet the requirements. Therefore, when users choose silicone rubber gaskets, they need to investigate the manufacturer's reputation and also consider their production capabilities.

Silicone has initially become silicone products after vulcanization molding, and silicone products have many sharp edges and burrs; This has a serious impact on the appearance and practicality of silicone products, so we need to carry out post-processing on silicone products. The post-processing of silicone products includes removing burrs (also known as flash edges). Sometimes we may encounter situations where the rough edges of the product break as soon as it comes out, and it can be easily peeled off in one go. Now we need to tear it several times; This seriously affects production efficiency. Silicone product manufacturers will talk to everyone about how to deal with the problem of difficult tearing of silicone product burrs.   Resolvent: 1. Check whether the vulcanizing agent is excessive and whether the storage time of the raw materials after mixing is too long; 2. Check if the mold temperature is too high; 3. Check if the exhaust frequency is too high and if the exhaust stroke is too large; 4. Is the operator's operating speed too fast? If so, reduce the vulcanization time or mold temperature.

For the question of how long silicone cups can last, let's first understand the material of silicone. What is silicone? Silicone material is internationally recognized as a safe, non-toxic, colorless, and odorless material, which is pollution-free and harmless to the environment. Because silicone has excellent characteristics such as high temperature resistance, low temperature resistance, hydrophobicity, and physiological inertness after vulcanization; So people make full use of the characteristics of silicone in various fields, and silicone has become a ubiquitous thing in our lives. Silicone is divided into universal silicone, high temperature and low temperature silicone. Even ordinary solid silicone can withstand temperatures up to 350 degrees Celsius instantly, which means that placing ordinary silicone in a high-temperature oven for one second can remove it without any problems. Moreover, silicone cups have been tested to be safe to use between -40 ℃ and 240 ℃, and they will not undergo any physical or chemical changes! How long can silicone cups last? In fact, the above is already clear. Silicone cups can withstand temperatures of -40 ℃~240 ℃, and after vulcanization, silicone has excellent resistance to high and low temperatures, hydrophobicity, and physiological inertness. For those who purchase silicone products, if they are not clear about the service life and aging rate of silicone materials, they will doubt the safety of silicone products. According to the characteristics of various silicone materials, the service life of silicone can last for hundreds of years in certain environments. It can be guaranteed that it will last for at least 10 years. Some people are worried that using silicone cups for so long may cause any changes in the silicone? The answer is no. The properties of silicone are inherently stable, and their chemical and physical mechanical properties change very little with temperature. So, you can use silicone cups with confidence.

We can see that the patterns on silicone screen printing are very beautiful, so someone will definitely be interested in the process of silicone screen printing. This is a detailed introduction to the silicone screen printing process. Screen printing is the earliest printing method. Screen printing is the abbreviation for "screen printing". Because screen printing requires a mesh board, it is also called screen printing. Generally, silk screen printing ink is thicker and brighter, and the printed patterns have a three-dimensional effect. Screen printing can also print finer lines and is suitable for large-area printing. Screen printing is the process of stretching silk fabrics, synthetic fiber fabrics, or metal wire mesh onto a frame, and using manual coating or photochemical plate making methods to produce screen printing plates. Modern screen printing technology uses photosensitive materials to produce screen printing plates through photographic plate making methods. Screen printing is the process of transferring ink through the mesh holes of graphics and text onto a substrate, forming an image that is identical to the original image. Silk screen silicone is a special type of silicone that is printed through screen printing. Now let's talk about how many times do silk screen silicone need to be printed? Silk screen silicone is divided into manual printing and machine printing. Manual printing requires multiple prints to form, but the printing is too slow and the production capacity is not high. Because it is manually scraped, some patterns may have slight ghosting if not careful. Screen printing can only print one color at a time. If color matching is required, first print the first color, then dry it, adjust the position of the screen plate, and then print the second color. And machine printing only takes one time to form. Silk screen silicone has the characteristics of environmental protection, non delamination of printing colors, multiple printing effects, good adhesion, delicate hand feel, excellent performance, non-toxic and harmless. After screen printing, the three-dimensional effect of the product will be enhanced and become more beautiful. Mainly because silk screen silicone is non-toxic and harmless, there is no need to worry about safety issues.

There are generally two ways for conductive silicone buttons to conduct electricity. One is to apply conductive adhesive to the bottom where conductivity is required to achieve conductivity. The other is to combine with conductive black particles during the molding process. The main reason for poor conductivity of silicone buttons is that the conductive black particles do not adhere to the button properly. So, what causes this phenomenon. The quality control points for silicone buttons are quite professional. In the early stage of mold development, it is necessary to control the strength of the mold. Experienced mold engineers know that the elasticity and feel requirements of silicone buttons are the most stringent for customers. Moreover, if the silicone mold is not well controlled during mold opening, it will be time-consuming, labor-intensive, and costly to modify and repair the mold in the later stage. We have our own mold room, and mold engineers are very familiar with the development process of silicone button molds. This is also an advantage in customizing silicone buttons, as they can think of unexpected aspects for customers and greatly shorten the project mold opening time. A perfectly flawless silicone button needs to go through the hands of more than N people before leaving the factory. The editor works on the workbench in the factory and quality inspection workshop every day, and there are endless inspections of silicone buttons. The quality requirements for silicone buttons are the strictest, basically finding high-quality products from good ones. The quality inspection supervisor arranges inspectors for silicone buttons who are also experienced employees for many years. They are familiar with the common defects and abnormalities of silicone buttons, which greatly improves work efficiency and reduces the outflow of defective products. One is the vulcanization temperature. If the vulcanization temperature of silicone buttons is too high or too low, it will cause the conductive black particles to fail to bond with the silicone or the conductive black particles to fall off. Secondly, if the vulcanization time is too long or too short, it can also lead to incomplete vulcanization of conductive silicone buttons, resulting in black particles falling off. Thirdly, during the molding and vulcanization process, poor exhaust of the product can lead to black particles falling off or poor air circulation. Finally, during the molding process of silicone raw materials, if the pressure of the molding machine is too low or the amount of raw materials is too small, it can also cause the conductive black particles to fall off. The conductive black particles of silicone products are the key to the conductivity of silicone keys, and poor bonding or falling of black particles with silicone keys can lead to poor conductivity. The light leakage of laser engraved buttons is mainly due to two reasons: thin spraying and deep laser engraving. Let's first understand what spray coating is. Before laser engraving, silicone buttons need to be sprayed with ink to cover the surface of the button and form a closed light shielding. It sounds simple, but in reality, it is difficult because some buttons need to be sprayed 3-4 times to completely block the light. Insufficient or uneven ink spraying can easily lead to light leakage. Laser engraving deep is easier to understand. Laser engraving is the process of carving patterns on an ink coating using a laser. The depth of laser engraving can be controlled, and if the engraving is too deep, it will pierce through the layers that do not need to be engraved.

Food grade can directly touch food/human body, while industrial grade can only be used in factories/machinery and must not be mixed. Please refer to these simple explanations for more details: 1.In terms of safety: Food grade: After strict testing, it does not contain heavy metals or toxic additives. High temperature cooking and microwave heating will not release harmful substances, meeting safety standards such as FDA and GB 4806. Industrial grade: No safety requirements, may contain impurities or toxic additives, high temperature may emit odors/toxic gases, and there are health risks when touching food and skin. 2.In terms of usage: Food grade: silicone spatula, baking mold, lunch box sealing ring, baby pacifier, dental glue, medical catheter. Industrial grade: door and window sealant, automotive seals, electronic equipment waterproof adhesive, industrial molds (for making crafts/cement). 3.In terms of experience: Food grade: Basically tasteless, washed 1-2 times to clean, and does not deform or precipitate even after repeated cooking. Industrial grade: has a pungent odor (difficult to remove), is prone to softening and deformation at high temperatures, and may also emit oil. 4.How to choose: When buying products that can be used to touch food/babies, you must check the packaging label for "food contact use" and "FDA/LFGB/GB 4806"; The price is too cheap, there is no safety label, and it is said to be "for food use". It is highly likely to be an industrial grade counterfeit. Don't buy it.

Do silicone daily necessities have health concerns? From pacifiers in babies' hands, to essential scraper molds for baking enthusiasts, to foldable water bottles loved by young people, a soft and elastic material - silicone - is rapidly integrating into every aspect of our daily lives. It claims to be heat-resistant, easy to clean, portable and environmentally friendly, quickly replacing some traditional plastic, glass and metal products. However, as its popularity skyrockets, questions arise: are these brightly colored and uniquely tactile silicone products really safe and harmless as advertised, while bringing convenience? Is it an ideal companion for modern life, or is there a hidden risk that we have not yet noticed? Do silicone daily necessities have health concerns. Silicone, its chemical essence is silicon dioxide, it is not the plastic (polymer) we often refer to. Thanks to its unique molecular structure, silicone daily necessities have many commendable characteristics. The most outstanding thing is its excellent temperature resistance. High quality silica gel can usually withstand a temperature range of -40 ℃ to 230 ℃ or even higher, which makes it safe to heat in the microwave oven, and can easily cope with the high temperature disinfection and sterilization of dishwashers. Secondly, it has excellent flexibility and chemical stability, is not easily brittle, is inert to most substances, and does not easily react with food or produce odors. In addition, its soft surface is not easy to scratch the cookware, and its anti slip effect is excellent, which together establish its stable position in the kitchen. For ordinary consumers, it is essential to master some simple identification skills. One is "smell". High quality food grade silicone is almost odorless when it leaves the factory, and should not produce a pungent plastic or acidic odor even when exposed to heat. The second is "watching", observing whether the color is uniform and transparent. Products that are too bright or contain bright colors may need to be alert to whether unqualified colorants have been added. The third is "stretching". High quality silicone has good toughness and resilience, and it is not easy to turn white when stretched by hand, and can quickly recover to its original state, while inferior products may deform or even tear. Although these methods cannot replace professional testing, they can help us screen out most products with obvious problems in the first place. In addition to the safety of the material itself, the correct use and maintenance of silicone daily necessities also directly affect their lifespan and hygiene condition. Although silicone is resistant to high temperatures, it is still necessary to avoid prolonged exposure to air or flames. When cleaning, although most silicone products claim to be dishwasher washable, hand washing can more effectively maintain their texture, and timely cleaning after use can also prevent oil stains from seeping in. For silicone with adsorption properties (such as spatulas), attention should be paid to checking the surface for dark stains that are difficult to remove, which may be a signal that needs to be replaced. Proper maintenance not only extends the service life of products, but also represents a continuous responsibility for health. From this, it can be seen that silicone daily necessities themselves are a positive material advancement, and the key to their safety lies in the producer's adherence to standards and the consumer's discernment of quality. When we hold a silicone kitchenware, we choose not only a tool, but also a consideration for our quality of life. It injects convenience and warmth into the fast-paced modern life with its unique flexibility and toughness, but only through marketing rhetoric, recognizing its material nature and safety standards, can it truly become our trusted life assistant, rather than a hidden burden. Wise choices and correct use are essential to ensure that this' silicone revolution 'truly serves our health and convenience, and warms our daily lives with the light of technology.

In today's rapidly developing technology, the performance of electronic devices continues to improve, and the heat generated during their operation is also increasing day by day. In order to ensure stable operation of equipment and extend its service life, thermal conductive silicone, a key heat dissipation material, has gradually entered the public eye. This article will provide a detailed introduction to the function and usage of thermal conductive silicone, helping you to gain a deeper understanding of this important material.   The function of thermal conductive silicone 1. Efficient thermal conductivity: Thermal conductive silicone can fill the gap between electronic devices and heat sinks, increase the contact area, significantly reduce thermal resistance, and thus improve heat dissipation efficiency. 2. Insulation protection: Thermal conductive silicone has excellent electrical insulation properties, which can effectively prevent short circuits between electronic components and ensure the safe and stable operation of the circuit system. 3. Shock absorption and buffering: This material has a certain degree of flexibility and elasticity, which can play a role in shock absorption and buffering when the equipment is subjected to vibration or impact, protecting electronic components from mechanical damage. 4. Moisture proof, dust-proof, and corrosion-resistant: Thermal conductive silicone can form a protective film on the surface of electronic devices, preventing the intrusion of moisture, dust, and corrosive substances, and protecting electronic components from environmental damage.   Usage of Thermal Conductive Silicone 1. Surface cleaning: Before using thermal conductive silicone, the surfaces of the heat source and radiator must be cleaned to remove oil, dust, impurities, etc., to ensure that the thermal conductive silicone can fully contact the surface and improve the thermal conductivity. 2. Application or installation: Thermal conductive silicone grease (paste like): If it is thermal conductive silicone grease, use a tool (such as a scraper, toothpick, etc.) to take an appropriate amount of silicone grease and evenly apply it to the surface of the heat source. Pay attention to applying it thinly and evenly to avoid accumulation or bubbles. Generally speaking, a thickness of 0.1-0.5 millimeters is recommended for application. Thermal conductive silicone film: For thermal conductive silicone film, cut the silicone film into a suitable shape and size according to the size of the heating element and heat sink, then remove the protective film, accurately place the silicone film between the heat source and heat sink, gently press it to make it tightly adhere. -Thermal conductive sealing adhesive: If it is a thermal conductive sealing adhesive, pour the adhesive solution into the area that needs to be sealed, ensuring uniform filling and no gaps. During the sealing process, tools can be used as needed to assist in fully covering the heating element with the adhesive solution.

There are various types of customized processing techniques for silicone products, and different types of silicone products require different production processes. Most products cannot avoid the silk screen printing process, which is not only used in the silicone industry. In daily life, many product patterns and logos need to be printed using silk screen printing. Due to its numerous advantages, silk screen printing can be recognized in many industries. Its printing process uses two-component liquid silicone and curing agent color paste to mix and produce the required silk screen colors, and finally completes the silk screen printing process through a silk screen machine. In the silicone product industry, its purpose is to achieve the engraving of product appearance patterns with fonts.   The screen printing process has many excellent characteristics compared to other processes. Firstly, it has good fluidity, strong adhesive viscosity and clear effect, high and low temperature printing stability, and good weather resistance and aging performance. The patterns printed by screen printing have a more three-dimensional and tactile feel, and the screen printing patterns also have excellent peel strength, wear resistance, and brightness; It also has waterproof, anti slip, breathable, high and low temperature resistance, and outstanding leveling properties. What are the details that silicone product manufacturers need to pay attention to during the screen printing process? The quality of silk screen printing is closely related to the quality of the pattern. Therefore, in some processes such as silicone buttons and silicone gift cups, the ink applied to the product is also crucial for the silk screen printing process. High quality ink can improve the quality of the pattern. However, some products may experience color fading after long-term use, mainly due to the following reasons: 1. The quality of screen printing ink is relatively poor, which affects the surface of silicone products and leads to poor screen printing effect; 2. After silk screen printing, the baking temperature of silicone products is too low or the baking time is too short, which leads to poor wear resistance of the silicone product patterns produced by silk screen printing. After several uses, the patterns begin to become blurry; 3. The surface of silicone products is too dirty and not cleaned before screen printing, which hinders the adsorption between screen printing ink and silicone, causing characters to fall off with a slight force.
