Product Description

1.Product Introductions:

Silica Gel is a granular, vitreous, porous form of silicon dioxide made synthetically from sodium silicate. Silica gel contains a nano-porous silica micro-structure, suspended inside a liquid. Most applications of silica gel require it to be dried, in which case it is called silica xerogel. For practical purposes, silica gel is often interchangeable with silica xerogel. Silica xerogel is tough and hard; it is more solid than common household gels like gelatin or agar. It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules.



Orange silica gel, also known as "cobalt-free color-changing silica gel", is also an environmentally friendly desiccant and belongs to silicone products. The appearance is orange or translucent glass-like particles. It has strong moisture absorption capacity and its appearance color will produce obvious color changes with the increase of moisture absorption during the moisture absorption process.It can be used as a raw material for environmentally friendly desiccants.
 

But not only that, blue silica gel is also possible.

Blue silica gel, also call "Color-changing silica gel " is an indicator adsorbent with high added value and high technical content after deep processing, which is made from fine porous silica gel, a highly active adsorbent.

Blue silica gel is ideal as a primary desiccant or blended with other desiccants in any application where visual control of moisture is required. sSORB silica gel beads are saturated with a moisture indicating solution that gives them a deep blue color when dry. The color changes from blue to purple to pink as it adsorbs moisture.
