Silicon Gift Good Thermal Stability And Stable Chemical Properties

Silicon Gift product is a kind of highly active adsorption material, which belongs to amorphous matter, and its chemical formula is Msio2 NH2O. Insoluble in water and any solvents, non-toxic tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid and no matter what the reaction. Various types of Silicon Gift with different manufacturing methods to form different micro-pore structure. The chemical composition and physical structure of Silicon Gift determine that it has many other similar materials difficult to replace the characteristics: High adsorption properties, good thermal stability, stable chemical properties, high mechanical strength and so on.

Silicon Gift According to its pore size is divided into: macroporous Silicon Gift, coarse pore Silicon Gift, B-type Silicon Gift, microporous Silicon Gift. Because of the different pore structures, their adsorption properties are characteristic. Thick-hole Silicon Gift in relatively high humidity conditions have a higher adsorption, fine-pore Silicon Gift in the case of low relative humidity is higher than the coarse-pore Silicon Gift, and B-type Silicon Gift due to pore structure between the coarse, fine-pore silica, the adsorption capacity between the coarse, thin hole. Macroporous Silicon Gift is generally used as catalyst carrier, matting agent, toothpaste abrasive and so on. Therefore, different varieties should be chosen according to different uses.

Silicon Gift adsorption moisture, you can use insolation, baking, drying and other methods of regeneration.

Silicon Gift desiccant----the main ingredient is silica, from natural minerals processed by purification into granular or bead-like. As a desiccant, its microporous structure (averaging 2 a). ) has a good affinity for water molecules. The most suitable moisture absorption environment of Silicon Gift is room temperature (20~32), high humidity ($number), it can reduce the relative humidity of the environment to about 40%.

Desiccant is a kind of water absorbent, which absorbs moisture from the atmosphere, and its drying principle is to adsorb the molecule in its own structure or chemically absorb water molecule and change its chemical structure to become another substance.

Silicon is used in applications where the conformal and mechanical strength are required in extreme or harsh working conditions. Silicon is easy to be molded and easily colored. It is used in a wide range of exposure to harsh operating and corrosive environments and meteorological products.

How should the shrinkage rate of silicone rubber products be controlled? As is known to all, rubber is an elastomer, so it is easy to stretch and shrink, but it is not equal to being compressed easily. Even if you compress it, it will hardly change any volume changes (shrinkage). However, the shrinkage rate after vulcanized rubber is 10 times times that of other materials-20 times times. In rubber molded vulcanization, how to control the shrinkage rate of rubber products, in the rubber mold molded vulcanization, the use of the prior to the rubber shrinkage after the design of the mold, so not because the shrinkage of quality problems.
