सिलिका जेल पाउडर का उपयोग

सिलिका जेल पाउडर has good thermal stability and chemical stability. It can selectively adsorb and purify isomer components from multi-component solutions. In the process of preparing सिलिका जेल पाउडर, a series of products with an average pore diameter of 20A°-20000A° can be produced by controlling different process conditions to adapt to the separation and purification of substances with different properties, molecular weights and molecular structures. The purity of सिलिका जेल पाउडर is as high as 99%. Compared with organic column packing, silica gel is a solid colloid with SiO2 as the matrix, and has a compact structure. Even if it is directly discarded, organic matter will be lost and the target product will be contaminated.
