Silica Gel is an amorphous form of SiO2 Which is chemically inert, non-toxic (is 100% environmental safe), and dimensionally stable. As we know, Relative Humidity is one of the major concerns of many facilities in all fields of life. For example, in medical industry, hospitals, factories, museums, and other public facilities. Why to Control moisture, eliminate fog, for instance, the humidity level inside your room during the summer is under very humid conditions over an extended period can leave you uncomfortable and adversely affect your home. Musty smells, rusting tools, blistered paint and moisture dripping from pipes are signs of excessive humidity. At this you should consider of using silica gel as desiccant. When the shipping and storage containers, cargo shipment are exposed to container rain” which forms on the inside of shipping containers while goods travel between different climate zone. Some kind of silica gel can adsorb 100% of its weight in moisture while providing 50 days or more of moisture protection for goods. Silica gel is mainly used as desiccant, but because the product is totally free from toxic, it is also widely used as adsorbent in the medicine refinement, fine electronic industry, cosmetic material, blood DNA field, Food industry, etc. Silica gel can be regenerated more times, when it is full of water, can be dried at the 100-200 degrees centigrade or in strong light of sun. but its property decreases, 5-10% per time. Because of the special property of the product, many new uses of silica gel are still on a developing stage. and all the manufacturers all over the world are striving toward the development of new products to meet the ever-changing needs of industry and other fields concerned.
Type A – clear pellets, approximate pore diameter: 2.5 nm, drying and moisture proof properties, can be used as catalyst carriers, adsorbents, separators and variable-pressure adsorbent.
Type B – translucent white pellets, pore diameter: 4.5-7.0 nm, liquid adsorbents, drier and perfume carriers, also may be used as catalyst carriers, cat litter.
Type C – translucent, micro-pored structure, raw material for preparation of silica gel cat litter. Additionally dried and screened, it forms macro-pored silica gel which is used as drier, adsorbent and catalyst carrier.
Silica alumina gel – light yellow, chemically stable, flame-resistant, insoluble except in alkali or hydrofluoric acid. Superficial polarity, thermal stability, performance greater than fine-pored silica gel.
Stabilizing silica gel – non-crystalline micro-porous solid powder, nontoxic, flame-resisting, used in brewery of grains for beer to improve taste, clearness, color and foam, removal of non-micro-organism impurities.
