The characteristics and applications of, SIL import O-ring seal products and so on.
1/ in fact, we are no stranger to silicone products and can be said to be everywhere in real life. For example, the sealing pad in the lid of the beverage bottle, the seal ring of the food box, the seal ring of the high pressure pot, the seal of the medical export, the seal of the door and window, the silica gel gloves and so on. But the main purpose of silica gel is to be widely used in industry. It has been widely applied in aerospace, instrumentation, atomic energy, electrical appliances, electronics, automobiles, machinery, metallurgy, chemical industry, medical and health fields.
The main characteristics of 2/ silicone rubber products:
A, good processing performance, easy to form and other advantages, can be extruded by hot air vulcanization, molding, casting and other methods to produce a variety of products.
B, excellent high temperature compression permanent deformation;
C, excellent weatherability, ozone resistance and ultraviolet radiation, and no cracking in the outdoor use for a long time.
D, high and low temperature resistance: the limit temperature is -60~250 C (recommended at -30`230 C), the high temperature of special silicone rubber can reach 300 degrees centigrade, and it can withstand low temperature to -100 C (TR10 can be at -100 C). In C are elastic - 60;
E and electrical insulation properties: the dielectric properties of silicone rubber are excellent, especially the dielectric properties at high temperature are much higher than those of general organic rubber, and dielectric strength is almost not affected by temperature in the range of 20-200 C.
Two, SIL import O-ring imported raw materials and main product categories
100%进口原料---美国杜邦、日本大金、德国朗盛等知名公司提供。 High quality raw materials ensure the excellent performance of the sealed products. Taiwan Asahi Meike XOK sealing technology is dedicated to providing first-class imported seal of the company.
Main products:
A, O type ring: all kinds of material rubber O ring, mainly NBR, HNBR, FKM/VITON, EPDM, FFKM, SIL, PU, CR, PTFE and so on;
B, ED ring, star ring, rubber gasket, rubber ball, flat ring, combination washer, pneumatic seals and non-standard pieces of rubber parts;
C, oil cylinder: spot is mainly TC skeleton oil seal, and other oil seals are also produced, such as Y type, U type, V type combination, stall, grai ring, dustproof ring, water seal and so on.
Three, properties and uses of imported SIL O-ring SIL silicone products
Silica gel is divided into large pore silica gel, coarse porous silica gel, B silica gel and fine silica gel according to the size of the silica gel. Because of the different pore structure, their adsorption properties are also different. Macroporous silica gel has higher adsorption capacity under relatively high humidity condition, and the silica gel has more adsorption capacity under relatively low humidity. However, the adsorption capacity of B silica gel is between coarse and fine pores due to pore structure between coarse and fine pores. 　 　　
1/ coarse porous silica gel
The coarse silica gel is also called C type silica gel. It is a highly active adsorption material, which belongs to amorphous material, and its chemical molecular formula is mSiO2 nH2O. Insoluble in water and any solvent, non-toxic and tasteless, chemical property is stable, except for strong alkali, hydrofluoric acid and no reaction with any substance. The appearance of coarse silica gel is white, and there are three kinds of products such as lump, ball and microsphere. Coarse pore spherical silica gel is mainly used for gas purifier, desiccant and deacidification agent for insulating oil. Coarse pore bulk silica gel is mainly used as catalyst carrier, desiccant, gas and liquid purifier.
2/ B type silica gel
The B type silica gel is milk white transparent or semitransparent spherical or lumpy particles. Kong Rong is 0.60 - 0.85ml/g with an average diameter of 4.5 - 7.0nm. It should be used as air humidity regulator, catalyst and carrier, pet mat, as well as raw material for fine chemical products such as silica gel.
3/ fine silica gel
The silica gel is a colorless or yellowish transparent vitreous body with an average distance of 2.0-3.0MM. It is mainly used in drying, moistureproof and antirust places. Such as the prevention of instruments, instruments, drugs, food, textiles and all kinds of packaging and other items. It can also be used as an air purifier to control the temperature of the air. In order to prevent the goods from being dampened by the high temperature in the course of transportation, the products can be effectively moisture-moisture-proof with this product.
