Silica Gel Usage and Synthesis:

Silica Gel has an open porous structure and is highly adsorptive and capable of adsorbing a wide range of substances. It does not react with any substance except strong alkali and hydrofluoric acid, and is insoluble in water and any solvent. It is non-toxic, tasteless and chemically stable. Various types of silica gel have different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, chemical stability, high mechanical strength, etc. Silica gel is classified according to its The pore size of silica gel is divided into: large pore silica gel, coarse pore silica gel, B-type silica gel, fine pore silica gel, etc.

Pharmacokinetics of Silica Gel:

Inorganic silica gel is a highly reactive adsorbent material that is usually produced by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid soaking. When dilute sulfuric acid (or hydrochloric acid) is added to an aqueous solution of water glass and left to stand, it becomes a watery silica gel and solidifies. The electrolytes dissolved in it are removed by washing with water. Na+ and SO4 2-(Cl-) ions, and after drying, silica gel can be obtained. If absorbing water, some silica gel moisture absorption is about 40%, even 300%. For gas drying, gas absorption It is used for gas drying, gas absorption, liquid dehydration, color layer analysis, etc. It is also used as a catalyst. If cobalt chloride is added, it will be blue when drying and red after absorbing water. It can be regenerated and used repeatedly. Silica gel is mainly composed of Silica is chemically stable and non-combustible. Silica gel is a kind of amorphous silica, the dust content of the workshop should be controlled to be no more than 10 mg/m3, and the exhaust air should be strengthened. The dust content in the workshop should be controlled to be no more than 10 mg/m3.

Clinical Application of Silica Gel:

Silica Gel The various types of silica gel have different microporous structures depending on their manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other The chemical composition and physical structure of silica gel determines that it has many characteristics that are difficult to be replaced by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. It is used as a desiccant, humidity regulator It is also used in industry as oil hydrocarbon decolorizer, catalyst carrier, variable pressure adsorbent, etc. It is used in fine chemical industry as separation and purification agent, beer stabilizer, coating thickener, toothpaste rubbing agent, matting agent, etc. It is used as separation and purification agent for fine chemical industry, beer stabilizer, coating thickener, toothpaste rubbing agent, matting agent and other chemical reagents.
