Introduction to column layers of silicone

1. Basic introduction

The column layer of silicone is made of high -quality silicone. The main feature is the difference in retention time to adsorbing different components in mixed substances; the purpose of separating and purifying.


2. Traits

The column layer of silicone is white and uniform particles, and the main ingredients are silicon dioxide. It has the characteristics of high purity and safety and hygiene.


It is a glue system with solid characteristics, which is composed of colloidal particles that form a condensed structure. Collagen particles are hydrophilic silicone (polysilicate) contraction, which is an amorphous substance. The gap between the column of the column to form the internal microre pore structure inside the silicone particles. Therefore, it is a high -quality adsorption material with a rich micro -hole structure, high -ratio, high purity, and high activity.


The main performance characteristics of column layers -adsorption characteristics depends on the microporous structure and internal pore surface surface formed by the production of raw silicone.


3. Use

The column layer of silicone is used for the separation and purity of the effective ingredients of Chinese herbal medicines, the preparation of high pure substances, refined oil products, dehydration and refining of organic substances, and the prominent advantages of column layer of silicone gum in biological engineering technology.

In the process of raw materials, the time of acid bubbles and aging is strictly controlled, and high -temperature burning technology is adopted. Therefore, the column layer of silicone has a rigid skeleton structure with high mechanical strength and can tolerate pressure within 30MPa.


The column layer of silicon glue has good thermal stability and chemical stability. It has a choice of adsorption and purifying the same division component from multiple partition solutions.


In the process of preparing column layers of silicone, a series of products that can produce a series of products with average pore diameter 20A °-20000A ° can be produced by controlling different process conditions to adapt to the separation and purification of substances of different properties, molecular weights and molecular structures. The purity of the column layer of silicone is as high as 99%. Compared with organic column fillers, silicone is a colloid with SIO2 as the matrix of solids. The structure is dense.
