Silica Gel Desiccant Silicon Dioxide Description
Silica gel is main component is silica. As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules. It absorbs water through physical adsorption, does not change its state after absorbing moisture, and has a strong hygroscopic ability, which can effectively protect food or medicine from moisture.
Silica Gel Desiccant Silicon Dioxide Use
Mainly used as desiccant, moistureproof beads, deodorant and adsorbent.It is widely used in the storage and transportation of instruments, instruments, equipment, leather, bags, shoes, textiles, food and medicine to control the relative humidity of the environment and prevent articles from being affected with damp, mildew and rust.the product can effectively remove dampness and moisture, so that the quality of the goods is guaranteed.
