With the continuous development of economy, more and more silica gel plates have been applied to our production and life. Today we come to understand the related knowledge of silicone plates.
Silica gel plate made of rubber material is a kind of high activity adsorption material, which belongs to amorphous material and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and odorless, 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 composition and physical structure of silica gel determine that it has many other similar materials that are difficult to substitute: high adsorption performance, good thermal stability, chemical stability, and high mechanical strength. According to the size of its pore size, silica gel can be divided into: large pore silica gel, coarse pore silica gel, B-type silica gel, and fine-pored silica gel.
Rubber material silica gel board has the following characteristics:
1. The separation effect is good and the number of plates is high.
2. Small spots for easy analysis.
3. The separation time is short.
4. High sensitivity, clear spots, non-proliferation
The use of rubber material silica gel plates is also very extensive: it can be directly used for rapid separation of many types of organic substances - qualitative or quantitative analysis, identification of trace impurities and major components in pharmaceuticals, pesticides, Chinese herbal medicines, organic chemical products, and foodstuffs and foods. Has been widely used.
