Silica gel manufacturers are generally customized according to the needs of assembly or modeling structure of separate mold production, then the integrity and accuracy of the drawings is very important, it directly determines whether the silica gel products out of the mold proofing can be qualified in a trial? If the design of assembly is too large, there will be the phenomenon of stuck keys; Silica gel products customized in the design of negative tolerance as far as possible, because silica gel elastic, too large size assembly is too loose, easy to fall off

Silica gel according to the size of its aperture is divided into: macroporous silica gel, coarse porous silica gel, B type silica gel, fine porous silica gel. Due to the difference of pore structure, their adsorption properties are different. Coarse pore silica gel in the case of high relative humidity has a higher adsorption capacity, fine pore silica gel in the case of low relative humidity adsorption capacity is higher than coarse pore silica gel, and B type silica gel due to pore structure between coarse and fine pore silica gel, its adsorption capacity is also between coarse and fine pore. Macroporous silica gel is generally used as catalyst carrier, extinction agent, toothpaste abrasive, etc. Therefore, different varieties should be selected according to different uses. After absorption of water, silica gel can be regenerated by exposure, baking, air drying and other methods. Safety performance

Silica gel is a kind of highly active adsorption material, is an amorphous substance, its chemical formula is mSiO2? NH2O. Insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any material. Various types of silica gel due to its different manufacturing methods and the formation of different microporous structures. The chemical composition and physical structure of silica gel determines that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength and so on.

Silica gel is mainly composed of silicon dioxide, stable chemical properties, non-toxic. Silica gel has a strong adsorption capacity, can produce a dry effect on the human skin. If silica gel into the eyes, need to wash with a lot of water, and seek medical treatment as soon as possible

Blue silica gel contains a small amount of cobalt chloride, toxic, should avoid contact with food and inhalation in the mouth, such as poisoning incidents should immediately seek medical treatment.

With silica gel was accepted by the people more and more, the application of silicone neighborhood is the more the better, people demand for silicone raw material also more and more big, the demand of the market future silicone raw materials is very optimistic, because the silicone is a weak cycle industry, the total demand is predictable and in foreign countries, many industries are now using silica gel, in China, The amount of silica gel in Guangdong province accounts for more than 80% of the total amount of the whole country, and it may increase in the future!

The advantages of silica gel are gradually found by people, instead of many other materials in our daily life, the magic of silica gel and silicone rubber raw materials is changing our life. From the product classification, application characteristics and precautions of silica gel, silicone rubber raw materials and liquid silicone rubber raw materials, there will be their respective differences. The application technology and main application uses of silica gel raw materials and liquid silicone rubber raw materials are well known. We can find, study and explore more. Understand silica gel, just to better understand yourself!

Silicone products customized not oil resources, which make silicone products similar to substitute for plastic products is the trend of The Times, at the same time, the silicone products can be applied to many plastic products can not achieve the purpose of the field, such as the pacifier, human organs, etc., so the silica gel products market prospect is very broad.

First, the quality of silica gel raw materials will cause silica gel products difficult to disassemble the edge, the poor quality of silica gel products customized raw materials its toughness is not enough, tearing strength is also obviously insufficient, in the process of disassembly is obviously difficult to disassemble the edge.

Second, in the molding stage, the product molding is relatively thick, so although the burr is relatively thick, the thickness improvement obviously also causes the difficulty of edge removal.

Three, vulcanization environment elements, vulcanization temperature should be suitable for, too high too low problems will cause difficult to disassemble, and vulcanization time also need good control, vulcanization time is too long will cause brittle goods, vulcanization time is too short will cause no effect of vulcanization stage, so the stage of vulcanization must be controlled well.

Four, the molding mold this aspect of the problem, if the mold self-disassembly design is unreasonable, the molding mold is too long, the molding mold wear is serious, the quality of the molding mold is not qualified, these situations will lead to the production of molding after it is difficult to disassemble.
