The main ingredient of silica gel desiccant is silicon dioxidewith a microporous structure, which has strong moisture absorption ability, non-toxic, tasteless, odorless, chemically stable, and is a highly active adsorption material.

Molecular sieve is a crystalline material with a uniform microporous structure, and these uniform pores can adsorb molecules smaller than their diameter into the cavity, and have preferential adsorption capacity for polar molecules and unsaturated molecules.

Industrial liquid sodium hydroxide, also known as liquid soda, caustic soda, liquid caustic soda, etc. The product is a colorless and transparent liquid, which is highly alkaline and highly corrosive. It can react with a variety of metals to form hydroxides, neutralize when exposed to acids, and produce salts and water. Strongly corrosive to skin. It can absorb chlorine and carbon dioxide, is easily soluble in water and releases heat, and is soluble in alcohol and glycerin.
