Silicone rubber sheet's process

The silicone rubber sheet is sprayed from powdered rubber by adding right amount of binder. Generally, the surface of the silicone rubber sheet is glass, and some manufacturers use aluminum foil to make the joint surface. The surface of the sheet is flat and uniform, and the main component of the silicone rubber sheet is SiO2·nH2O. Its chemical propertie is stable, and it does not react with other acids and bases except strong alkali and hydrofluoric acid.

Thin-layer chromatography silica gel plates can be directly used for qualitative and quantitative analysis of various types of organic substances, and are widely used in the identification of trace impurities and main components of medicines, pesticides, Chinese herbal medicines, organic chemical products and foods.

The thin-layer chromatography silica gel plate and the high-efficiency thin-layer chromatography silica gel plate are prepared as follows: Adding an appropriate amount of binder to the high-quality thin-layer chromatography silica gel, and then coated on a glass substrate. The rubber sheet should have a specified pore volume, pore distribution and specific surface.
