Feature remote control button silicone material
Silica gel is a highly active adsorption material is amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, it does not react with any substance except alkali, hydrofluoric acid. Various types of silicone because different manufacturing methods form different pore structure. Silica gel chemical composition and physical structure, silica remote control button determines that it has many other features of similar materials difficult to replace obtained: adsorption properties, thermal stability, chemical stability, high mechanical strength. Silica according to the size of the aperture is divided into: large pore silica gel, rough hole silica gel, B type silica gel, pore silica gel. Due to the different pore structure, adsorption properties so they have their own characteristics. Rough-silica gel in the case of high relative humidity had a higher adsorption capacity, pore silica gel in the case of low relative humidity higher than the coarse pore silica adsorption capacity, while B-type silica gel due to the pore structure between the coarse pores between silica gel, the adsorption amount between the crude, between pores. Wide pore silica is generally used as a catalyst carrier, matting agents, toothpaste abrasive. You should choose different varieties for different purposes. Silica gel adsorption of water, you can use exposure, burning baking, or air regenerated.
[Safety] Silicone main component is silicon dioxide, chemically stable, non-toxic. Silicone has a strong adsorption capacity, silica remote control button on the human skin can produce desiccation. If the silicone into the eyes, need plenty of water and seek medical treatment as soon as possible. Blue silicone because it contains a small amount of cobalt chloride, toxic, should avoid contact and inhalation mouth and food, such as the occurrence of poisoning should immediately seek medical treatment. [] The main purpose of using silica gel has the characteristics of strong adsorption of quickly and effectively adsorbs moisture inside the sealed package, chemically stable, non-toxic; coupled with constant innovation and development in recent years, a variety of silicone has been widely used in pharmaceutical purification, DNA isolation, food drying, high-precision electronics, fine cosmetics, water purification, beer purification, and other advanced coatings and resin production or preservation.
In our daily lives and production activities, the silica is often used in the following areas: precision optical instruments, electrical and electronic packaging dry mold; leather drying areas, such as placement in leather, leather bags, shoes play inside the shelf life of dried effects; food drying regard, common in on biscuits and fried foods in order to ensure the food crisp; Drug drier side, put in the bottle, make sure to extend the shelf life of drugs; container drying: Silicone remote control buttons transport containers will form the box on the different latitudes "within the Rain", if you use silica gel desiccant, it can absorb the equivalent of its own weight of water, for ocean transportation for up to 50 days in the process, can effectively reduce the dew point leaving the container The condensate phenomenon under control. Class hotel with the items, such as placing in the closet, shoes and bed, odor adsorption, keep the air dry and fresh.
