Production process and application of water resistant aluminum silica gel

The water resistant aluminum silica gel has better adsorption and separation performance than ordinary aluminum silica gel. The water resistance of particles has been significantly improved, and the durability to humidity changes and pressure changes has been improved. It is a new multifunctional product based on aluminum silica gel, and is widely used in petrochemical industry or other fields of gaseous substances.

On the basis of maintaining a series of properties of the original ordinary aluminum silica gel, the water resistant aluminum silica gel can be better applied to desiccants, adsorbents, various catalyst carriers, etc. Background technology: Water resistant aluminum silica gel is an important inorganic chemical product. The chemical composition and physical structure of silica gel determine that it has the characteristics that many other materials do not have: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. Therefore, it is widely used in desiccant, absorbent, moistureproof agent, catalyst carrier, filler, etc With the development of analytical technology, pesticide, paper making and coating technology, silica gel has gradually become refined and widely used, and its application in analysis, separation, catalyst carrier and coating has been expanding.

Silica gel is classified according to its shape, size, pore diameter, use, adsorption characteristics, etc. Different varieties have different applications, but ordinary silica gel has a disadvantage that is difficult to overcome: it bursts when encountering water. This has shortened the use time of silica gel and increased the use cost to a certain extent.
