Silica Gel Beads

Product Details

Silica gel desiccant is a kind of highly active adsorbing material, which is usually obtained by the reaction of sodium sulfate and sulfuric acid and after a series of post-processes such as aging and acid foam. Silicic acid is an amorphous substance with chemical formula msi02 and nH20, which is insoluble in water and any solvent . It is poisonless and tasteless, having good chemical stability. Due to different manufacturing methods, various types of silica gels have different microporous structures. The chemical and physical structure of silica gel has determined that it has many characteristics difficult to replace by other similar materials: good adsorption, stable chemical properties, high mechanical strength and so on.

Feature: Silica gel Packets is a kind of highly active adsorbing material, which is usually obtained by the reaction of sodium sulfate and sulfuric acid and after a series of post-processes such as aging and acid foam. Silicic acid is an amorphous substance with chemical formula msi02 and nH20, which is insoluble in water and any solvent  except for strong base hydrofluoric acid. It is poisonless and tasteless, having good chemical stability. Due to different manufacturing methods, various types of silica gels have different microporous structures. The chemical and physical structure of silica gel has determined that it has many characteristics difficult to replace by other similar materials: good adsorption, stable chemical properties, good thermal stability, high mechanical strength and so on.


Silica gel desiccant meets with ROHS, REACH and other environmental protection requirements

It is free of harmful substances such as DMF(dimethyl fumarate). Through FDA certification, it is a desiccant which can be used in direct contact with food and drug. 


Desiccant storage precautions

1、Seal off useful desiccant, take as many as you want

2、The desiccant that has not been used up should also be sealed instead of being placed at will. Must keep the desiccant sealed , and separated from the outside air. The effect will not be greatly affected when it is used next time.

3、Carefully handle during transportation to avoid scratching of the inner and outer packaging and keep the transportation and storage environment cool and dry.


Introduction: The main component of silica gel is amorphous silica, transparent or milky white irregular granular or spherical solid. Open porous Structure, strong adsorption, can absorb a variety of substances, is a high performance active adsorbent.


Features

a. It is non-toxic, tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. It is safe and reliable for desiccant adsorption materials that can be used for direct contact with pharmaceuticals and foods.

b. Silica gel has strong adsorption capacity under various conditions.

Indicating silica gel:

Description: The indicator silica gel mainly includes blue silica gel and orange silica gel. The orange silica gel contains orange to green and orange to white. The color-changing silica gel has the same performance as white silica gel. After moisture absorption, the color changes and it is easier to observe the moisture absorption state.

Note: (1) RH = 20%, that is, when the air humidity is 20%, 100 grams of silica gel can adsorb 10 grams of water, and generally adsorb 11 grams of water.

(2) The time of complete adsorption is about 48 hours.
