Introduction of the Silica gel powder

2022-08-10

Silica gel powder is made of silica gel as raw material. Its main feature is that it can achieve the purpose of separation and purification through the difference in adsorption and retention time of different components in the mixture.

Silica gel powder is white uniform particles, the main component is silicon dioxide. It has the characteristics of high purity, safety and hygiene.

It is a colloidal system with solid characteristics, consisting of colloidal particles forming an agglomerated structure. Colloidal particles are polycondensates of hydrated silica gel (polysilicic acid), which are amorphous substances. The gaps in the aggregate of the colloidal particles form the micropore structure inside the silica gel particles of the reagent column chromatography. Therefore, it is a high-quality adsorption material with rich microporous structure, high specific surface area, high purity and high activity.

The main performance characteristics of reagent silica gel powder - adsorption characteristics, depend on the microporous structure and inner pore surface formed during the production process of raw silica gel.

Silica gel powder is used for separation and purification of active ingredients of Chinese herbal medicines. Preparation of high-purity substances. Petroleum products are refined Organic substances are dehydrated and refined

Silica gel powder is made of high-quality silica gel with high transparency, excellent adsorption performance, and ideal separation function for similar properties, structures and even isomers; in the production process of raw materials, the acid foam and aging time are strictly controlled , and adopts high-temperature calcination technology, so the silica gel powder has a rigid skeleton structure, high mechanical strength, and can withstand pressure within 30MPa. Silica gel powder has good thermal stability and chemical stability, and can selectively adsorb and purify isomer components from multi-component solutions. Separation and purification of substances of different properties, molecular weights and molecular structures.
