Silicone main raw material processing system works, are called silicone products. Silica gel is composed of silicate gel dehydration appropriate particle size different porous material. With open porous structure, which can adsorb many substances, is a kind of very good desiccant, adsorbent and catalyst carrier. Silica gel adsorption is mainly physical adsorption, can be recycled and repeatedly used. Adding acid to alkali metal silicate, such as sodium silicate solution, acidification, stir and add a certain amount of electrolyte, namely generate silicate gel; Or in the concentration of sodium silicate solution adding acid or ammonium salt can also generate silicate gel. Silicone acid congealed gel will rest for a few hours of aging, then wash with hot water soluble salts, under 60 ~ 70 ℃ drying and activation when about 300 ℃, can get the silicone. Silicone gel with cobalt chloride solution after soaking and drying and activation, available color silica gel.
Food-grade silicone non-toxic tasteless, insoluble in water and any solvents, green product is a highly active. Food-grade silicone inherent thermal stability (to 40 ℃ — 230 ℃). Suitable for different occasions. Products with good softness, meet different needs.
High temperature resistant, suitable temperature range – 40 to 230 degrees Celsius, can be used in the microwave oven and the oven.
Easy to clean: silica gel produce silicone products after using in water, it will be clean again, can also be used in the dishwasher to clean.
Long life: silica gel material chemical performance is stable, making the products, have a longer life expectancy than other materials.
Soft, comfortable: thanks to flexible silicone materials, cake mold product feels comfortable, highly flexible, not out of shape.
A variety of colors: can according to the needs of customers, allocate different beautiful colors.
Environmental protection non-toxic, from raw materials into the factory to the finished product delivery does not produce any toxic or harmful substances.
Electric insulation performance: silicone rubber with high resistivity, and in a wide temperature range and frequency range of the resistance would remain stable. At the same time the silicone of high voltage corona discharge and arc discharge has the very good resistance, such as high voltage insulator, TV high pressure cap, electrical components, etc.
Low temperature resistance: ordinary rubber minimum temperature threshold for 20 to 30 degrees, whereas silicone rubber are at 60 degrees to 70 degrees still has good elasticity, some special formulation of silicon rubber can also withstand extremely low temperatures, such as low temperature sealing ring, etc.
Electrical conductivity: when join the conductive filler (such as carbon black), silicone rubber has good conductivity, such as a keyboard, electric heating element, antistatic conductive contact part, high voltage cable shielding, medical therapy conductive film, etc.
Hou resistance: ordinary rubber ozone generated by corona discharge under the action of rapid degradation, and silicone rubber is not influenced by ozone, and for a long time under the condition of ultraviolet radiation and other climate, its physical performance, only small changes, such as outdoor use of sealing materials, etc.
Thermal conductivity: when add some thermal conductive filler, silicone rubber has a good thermal performance, such as heat sinks, thermal conductive gasket, photocopiers, fax machines, roller of thermal conductivity, etc.
Radioresistance: contains phenyl silicone rubber radiation resistant is greatly increased, such as electric insulation cable, connector by nuclear power plants, etc.
