How to classify silica gel in the market and what are the differences in its use?

Silica gel on the market can be divided into three types: A-type silica gel, B-type silica gel and C-type silica gel. Today, Weiqi will introduce these types of silica gel to you.

1. Type A silica gel

[Characteristics] It has small pore size and large specific surface area, and belongs to dry, low humidity and high adsorption, that is, the adsorption effect is good when the relative humidity is 20-50%. Its advantage is fast adsorption when the relative humidity is low, but its disadvantage is low total adsorption capacity.

2. Type B silica gel

[Characteristics] Type B silica gel is a milky transparent or translucent spherical or massive particle, whose structure is between coarse and fine pores, with an average pore size of 40-70A, a specific surface area of 400-550m2/g and a pore volume of 0.6-0.75ml/g. 。

[Main uses] Type B silica gel is an excellent adsorption material, which can be used as liquid adsorbent, adsorption desiccant, catalyst carrier, bedding for keeping domestic pets and making fragrant silica gel. The characteristic of is based on the relationship between type A and type C.
