Old science - common sense Solid silica gel with liquid silicone difference between how

In life we should have seen many different kinds of silicone products, but they don't know if you have noticed that not every one is a material, in addition to the appearance and color, perhaps you can't see the difference between it, in fact, there are different in terms of hardness and tensile elastic, regardless of the mainest is also have different difference on material, then you know where the difference is that it? Interlaced, as the saying goes, such as the hills, in the silicone products industry also has a very wide range of knowledge, today we went to see what little common sense in the silicone products, including silica gel was divided into organic silicon and inorganic silicon, and can be divided into the liquid silicone with solid silica gel silica gel products: liquid silicone liquid silicone is relatively solid for high temperature vulcanization silicone rubber, for the liquid rubber, has good liquidity, sulfide is fast, more safe environmental protection, can fully meet the requirements of food grade. Solid silica gel solid silica gel is a kind of cell type and the elasticity of polymer materials, has a high temperature resistant, cold resistant, solvent resistance, towering resistance, resistance to glue, electrical insulation, chemical industry and so on characteristics, has a wide application range. Liquid silicone and the comparison of solid silica gel shape as the name implies the silicone is in liquid state, liquid. Solid silica gel is a solid, not liquid. Safety liquid silicone is high transparent high security of food grade material, molding without adding curing agent and other auxiliary materials, sealed feeding forming. Solid silica gel is transparent environmental protection material, molding need to add curing agent vulcanization molding time, open mode feeding forming. Forming method is liquid silicone injection molding liquid silicone rubber ( LSR) : the full name for the injection molding liquid silicon rubber, curing equipment for injection moulding machine. Injection molding machine has a technological process is very simple, Don't need to be in the process of high temperature glue ingredients, mixing, blanking, material and process, only one of the workers take products) , the products are high precision, All artificial program before molding all replaced by a machine) , high yield, A/B glue mixing under A certain temperature for A few seconds to shape) , province, the province electricity, materials and so on many advantages, can produce all glue products. Is solid silicone rubber molding is pieces of solid material, through mixing, mixing machine and cutting machine cut into products and mold the right size and thickness, a mold, after pressure molding machine under a certain temperature. Stripping along the lines of the plastic products, also need to clean up the mold and so on. Liquid silicone and solid silica gel products how to distinguish the high transparency liquid silicone products, no peculiar smell, product has the injection gate. Transparency is low, solid silica gel products are cover the fragrance of vulcanizing agent, vulcanizing agent or other products without the injection gate. Liquid silicone commonly used in baby products and kitchen supplies and medical supplies can be direct contact with the food and the human body. Solid silicon generally use the articles for daily use and miscellaneous pieces of industrial and automotive parts, etc. , using more extensive.
