Product Description

 Desiccant Silica Gel 2~5MM 2G, 25kg pack in Food Industry, White,Blue,Yellow,Green colour

 Silica gel is a transparent, glass-like, granular particles, usually obtained by the reaction of sodium silicate and sulfuric acid, and after a series of processes such as aging and acid bubbles. Its 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.

Technical Parameter:

called Self-indicating silica gel. The specification is
As follows:
1. Form: Spherical or crystal(lump)
2. Size: 0.5-2mm, 1-3mm, 2-5mm, 3-5mm, 4-6mm, 4-8mm, etc.
3. Packing: 25kgs/bag, 25kgs/drum, 150kgs/drum, 800kgs/bag
4. Color change: Orange to green, or orange to white

Silica gel orange is methyl-violet because of it has an orange color. Orange silica gel is use for moisture absorption process on industrial level. It is no side effects in environment and safe for health because of its organic nature and also it is non-toxic. When it becomes moisture free, the orange beads color is turns to dark green to black. Like blue silica gel orange silica gel is also an indicating.
