Liquid silicone bracelet manufacturer introduction, transparent or milky white granular solid. It has an open porous structure, strong adsorption, and can adsorb a variety of substances. Add dilute sulfuric acid (or hydrochloric acid) to the aqueous solution of water glass and let stand, it will become a hydrous silicic acid gel and solidify. The electrolyte Na + and SO4 2- (Cl-) ions dissolved in it are washed away with water. After drying, silica gel is obtained. If it absorbs water, some silica gel absorbs about 40% or even 300%. Used for gas drying, gas absorption, liquid dehydration, chromatographic analysis, etc. It is also used as a catalyst. If cobalt chloride is added, it will be blue when dry and red when it absorbs water. Reusable repeatedly.

The main component of silica gel is silica, which is chemically stable and does not burn. Silica gel is an amorphous silicon dioxide. The dust content of the workshop should be controlled at no more than 10 mg / m3. Exhaust air should be strengthened and masks should be worn during operation.

Liquid silicone bracelet manufacturers stated that silica gel has a strong adsorption capacity and can have a drying effect on human skin. Therefore, work clothes should be worn when operating. If the silicone enters the eyes, it needs to be rinsed with plenty of water, and seek medical treatment as soon as possible.

Blue silica gel contains a small amount of cobalt chloride, which is potentially toxic. Avoid contact with food and inhalation. If a poisoning event occurs, you should seek medical treatment immediately.

Overview of liquid silicone bracelet manufacturers, due to the adsorption of water vapor or other organic substances in the medium during the use of silica gel, the adsorption capacity decreases and can be reused after regeneration.
