1. Features:
Silica gel desiccant is a highly active adsorption material, which is usually prepared by reacting sodium silicate and sulfuric acid, and through a series of post-treatment processes such as aging and acid foaming. Silicic acid is an amorphous substance, and its chemical formula is mSiO2 and nH2O. Do not tolerate water or any solvents. It is non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical structure and physical structure of silica gel determine that it has many characteristics that are difficult to replace with other similar materials: strong adsorption performance, good thermal stability, stable chemical properties/high mechanical strength, etc.

[Applications]
It is suitable for medicines, machinery, optics and electronics, precision instruments, meters, seeds, processed foods, tea, various chemical fiber textiles, leather shoes, leather, sports shoes, cultural relics archives, cameras, arts and crafts and other items that need to be moisture-proof and mildew-proof, and is widely used.
2. Storage and packaging
Silica gel desiccant has a strong ability to absorb moisture, so it should be stored in a dry place. There should be shelves between the packaging and the floor. The packaging materials include steel drums, paper barrels, cartons, plastic bottles, polyethylene plastic composite bags, flexible container bags, etc. For specific packaging specifications, please refer to the classified product description. During transportation, rain, moisture and sun should be avoided.
[Packing]
Silica gel desiccant products are non-toxic and tasteless, and can be used directly after removing the outer packaging (except for direct contact with food and medicine), and generally do not need to be treated again.
1. The inner packaging of this product is sealed with plastic film and moisture-proof, and the outer packaging is made of double hard corrugated boxes.
