It has many advantages, such as fast adsorption, quick desorption, chemically stable, nontoxic, and tasteless. Besides, its selective adsorptive capability is higher than fine-pored silica gel.
Silica Gel Type B
Shape: Pellets or lumps. Color:milky white,transparent or translucent.
Porevolume:0.60-0.85ml/g.Average pore diameter:4.5-7.0nm Specific surface area:450-650m²/g.Structure lying between macro-pored and fine-pored silica gels.
Silica Gel Type C
Shape: Pellets
Color: Cream. Translucent. Micro-pored structure.
A型硅胶
主要用于二氧化碳气体的回收、分离以及净化,用于合成氨工业、食品饮料加工工业等制取二氧化碳,亦可用于干燥、防潮及有机产品的脱水精制等。
B型硅胶
主要用作液体吸附剂、干燥剂和香料载体,也可用作催化剂载体,硅砂等。
C型硅胶
本品用于制备硅砂的原料,经进一步烘干和筛选可形成粗孔硅胶,用作干燥剂、吸附剂和催化剂载体。
Silica Gel Type A
Variable-pressure adsorption is a kind of new high-technology used for gas separation and purifying. Mainly used for the recovery, separation and purifying of carbon dioxide gas. It is used for preparation of carbon dioxide in synthetic ammonia industry, food & beverage processing industry, etc. It may also be used for drying, moisture absorption as well as dewatering of organic products.
Silica Gel Type B
Mainly used as liquid adsorbents, drier and perfume carriers, also may be used as catalyst carriers, silica sands, etc
Silica Gel Type C
Used as the raw material for preparation of silica sand. After being further dried and screened, it forms macro-pored silica gel which is used as drier, adsorbent and catalyst carrier.
