Static and Dynamic Moisture Absorption Rate of A Type Silica Gel Desiccant

- Aug 02, 2019-

Type A silica gel desiccant, also known as pore silica gel desiccant, includes fine-pore spherical silica gel and fine-cell block silica gel, and the appearance is transparent or translucent glass. The average pore diameter is 2.0-3.0 nm, the specific surface is 650-800 m2/g, the pore volume is 0.35-0.45 ml/g, the specific heat is 0.92 KJ/kg.°C, and the thermal conductivity is 0.63 KJ/m.Hr.°C.


Application

Mainly used for drying, moisture proof, can also be used as catalyst carrier, adsorbent, separating agent, and pressure swing adsorption, color changing silica raw materials.
