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 pad life above which to consider its adhesive paper and use strength.

In the process of production and processing, the silicone products produced sometimes have the reason that the surface is not smooth. So what happens is that   What's the reason? 1, first confirm whether it is because of the mold. If the mold itself is not smooth, then the surface of the product produced will also be It's not smooth. 2. Check whether enough curing agent is added. If the amount of curing agent added is insufficient, it will cause insufficient surface curing of the product, there will be A slimy feeling. 3. Check whether the stirring of the curing agent is uniform. If the stirring of the curing agent is not uniform enough, there will be sufficient curing while curing Inadequate situation.

With the rapid development of silicone products, the production technology of silicone keys is also rapidly improved and mature, silicone keys are used in various industries, and the silicone keys made are more beautiful, some will screen print logo, screen print font, feel very good to use, the use of life is also very long, usually the number of use of silicone keys is about 200,000 times, There are some more exquisite silicone buttons are crystal clear, the surface is smooth and beautiful; In fact, the surface of the silicone button is smooth and beautiful because it has been processed by the glue dropping process.   So, how to carry out the glue dropping process of silicone keys?   1. Generally, the rubber dropping of silicone keys uses epoxy resin as a material, and then mixes it with the curing agent, and then drops it on the surface of the silicone keys, and then puts it for a certain period of time, after it dries, the silicone keys will be more beautiful, and also protect the appearance of the silicone keys from damage; 2 silicone button is anticorrosive, waterproof, wear resistance, good-looking and other advantages, good-looking is its crystal clear appearance, can increase the gloss of the product, such as the silicone button drop process of the application range is relatively wide, can be used for glass, metal, ceramics and other materials production process; 3. Generally, when the glue dropping process is carried out, high purity epoxy resin and curing agent will be mixed and prepared in proportion, and then put into the glue drip irrigation, and then drop a certain epoxy resin on the silicone button with the glue drip irrigation, and then place the silicone button after the glue drop for about 12h, so that it is fully cured, and after the curing is completed, the glue dropping process will be completed. In short, the glue dropping process is an important part of the production of silicone keys, so that the production can not only achieve crystal clear silicone keys, but also make the silicone keys have a good feel and gloss, notes: can not be placed too much epoxy resin, to prevent the production of poor products.

For consumers who do not understand the silicone material, the physical hardness of silicone rubber products may produce an ill-informed mind, the size of the product is the same without too much change, and the relationship between the formula and various physical properties is not complete to understand, all kinds of silicone, rubber and other material raw materials have its hardness and softness characteristics, natural silicone products are no exception, So why silicone material can be used in all walks of life in the world, because of its excellent hardness.   Different silicone products have its unique performance and process requirements, such as silicone silicone seals, silicone accessories, etc., can choose the most suitable polymer and match and reasonable deployment, in the hardness and softness to achieve close adhesion sealing shock absorption, waterproof oil and other effects, and hard and soft physical properties are still closely related to the formula and raw materials of the product. The debugging of the formula can try out various performance differences and functions, so the hardness and softness debugging still need to be careful, otherwise the hardness and softness errors are likely to cause inevitable trouble.   We all know that silicone material has good tensile strength, and the tensile strength of the index depends on the degree of hardness and softness of the product, silicone rubber products manufacturers generally the hardness of the manufacturer is about 20-80 degrees, the lower the hardness of the product tensile strength is better, generally can reach about 300%, the minimum is about 20%, However, it still depends on the structure and shape of the silicone product.   Silicone material is indispensable this is the tearing strength, silicone rubber material will be due to force and other factors and tear phenomenon, this is one of the inevitable phenomena of all rubber, and cracks and cracks caused by force cracking phenomenon occupy a minority, because silicone rubber with conventional hardness basically no tear rupture phenomenon, Materials with higher hardness are likely to tear due to the diffusion of the crack mouth.   Therefore, the tensile force and hardness of silicone products are important indicators of the material, silicone processing manufacturers in the vulcanization production procedures, the greater the silicon molecular weight of the compound, the greater the effective cross-linking fixed elongation stress. In order to obtain the specified constant elongation stress, the crosslinking density of the material with small molecular weight can be appropriately increased. Any structural factor that increases intermolecular forces. Increasing the density of silica gel material can prevent the hardness of the product from affecting the tensile strength of the product.

At present, there are hundreds of manufacturers of rubber products for automotive vibration reduction in China, and their products mainly include rubber springs, rubber air springs, frame beams, engine suspension shock absorbers, torsional dampers, etc. It plays an important role in limiting vehicle emissions, reducing noise, improving ride comfort and safety. With the rapid development of the automobile industry, especially the requirements for safety, comfort and easy driving are getting higher and higher, the amount of silicone products for automotive vibration reduction is increasing year by year, and the market demand for domestic automotive vibration reduction rubber products is about 150 million in 2008, and the number of high-end car production is increasing in the future. The market demand for rubber products for automotive vibration reduction is growing faster, so the demand for materials is also diversified. However, it is necessary to choose according to the different parts of the product used, from the consideration of fatigue resistance and creep performance, choose natural rubber; If you want to improve its heat resistance, choose styrene butadiene rubber; If the dynamic heat generation is small, you can choose butadiene rubber; If the rubber vibration reduction product is in contact with various oil media at work, nitrile rubber is selected; Due to stricter restrictions on automobile exhaust emission standards, the temperature of the engine and exhaust pipe is increased, and the rubber used in these parts needs to use EPDM rubber with high heat resistance.   The future development direction of China's automotive shock absorber is standardization and serialization, and the emphasis should be placed on the hydraulic shock absorber and torsion shock absorber that have been successfully applied abroad. Improve the level of detection and testing technology, develop new vibration damping rubber materials, the development of rubber vibration damping materials should further improve its heat resistance, the development of low dynamic rate, high damping new elastomer materials.

1. The tensile strength of rubber with small molecular weight increases with the increase of molecular weight. Generally, the tensile strength of rubber with molecular weight between 30-350,000 is the best.   2. The tensile strength with narrow molecular weight distribution is higher.   3, when there are polar substituents on the main chain, the tensile strength increases with the increase of intermolecular forces. For example, in nitrile rubber, the acrylonitrile content increases and the tensile strength increases.   4, tensile strength increases with the increase of rubber crystallinity. Such as NR, CR, CSM, IIR have higher tensile strength.   5. After the rubber molecular chain orientation, the tensile strength in the parallel direction increases, and the tensile strength in the vertical direction decreases.   6. Tensile strength decreases with the increase of crosslinking bond energy, and peaks with the increase of crosslinking density. The relationship between crosslinked bond type and tensile strength decreases in the following order: ionic bond -- polysulfide bond -- disulfide bond -- mono sulfur bond -- carbon-carbon bond   7, small carbon black particles and low structure (such as high wear resistance of low structure), surface oxygen-containing groups (such as slot black) its tensile strength, tear strength, high elongation.   8, the filler particles are small, the surface area is large, the surface activity is large, the reinforcement effect is good. As for the relationship between structure and tensile strength, the structure of crystalline rubber is not good for tensile strength, but for non-crystalline rubber is the opposite. The amount of carbon black in soft rubber is generally between 40-60 parts.   9. When the amount of softener exceeds 5 parts, the tensile strength of the vulcanized rubber will be reduced.   10. Other methods to improve tensile strength. Such as NR/PE, HS blend, NBR/PVC blend, EPDM/PP blend and so on.

Silicone cushion in the shipbuilding industry, silicone cushion reputation is a recognized fact; In the telecommunications industry, the silicone cushion with excellent quality and service has also won the favor by virtue of its good physiological stability. So what are the advantages of such a popular silicone cushion? Advantage 1, silicone cushion high temperature resistance Many industrial machines will be equipped with shock-absorbing cushions when installed, but because the machine will continue to heat up, the service life of ordinary cushions is very short. The silicone cushion has good physiological stability and shows excellent high temperature resistance, so the silicone cushion that will not be melted by high temperature is widely used in civil industry. Advantage 2, silicone cushion solvent resistance is good The expansion of the application range of silicone cushion is inseparable from its excellent solvent resistance.

Advantage 3, silicone cushion electrical performance is good Ordinary cushion will become a super conductive body after moisture, which has an incalculable devastating impact on electrical equipment. In contrast, the silicone cushion has excellent electrical properties, and will heat up in a short time when the humid air comes, maintaining good electrical properties, thus protecting the machine. Advantage 4, silicone cushion tear resistance Some buffer pads with small tear resistance coefficient are easy to crack after bending and can not be used. The silicone cushion has excellent elasticity and excellent tear resistance, and can withstand long-term tearing under normal circumstances, without damage.

How to identify inferior silicone tube?   With the development of the silicone industry, many industries now need to use silicone tubes, in order to prevent the purchase of inferior silicone products, the following is a brief introduction to how to identify inferior silicone tubes?   1, how to judge the poor quality silicone tube: (1) Test the elasticity of silica gel, silica gel is more fragile, can try the elasticity, assuming that the elasticity is good, it may be rubber; Assuming it's not very elastic, it could be silicone. (2) Look at the color of the product, silicone is colorless and transparent, to make transparent silicone rubber products must be made of silicone as a material. (3) Smell, rubber and latex products have a strong taste, the smell is very pungent, some manufacturers increase the smell to cover up the taste, therefore, the choice of silicone materials will be better.
