Product Description
Acid silica sol products are independently developed by our company. Through unique purification, surface modification, acid stability and other processes, the products have the characteristics of adjustable PH value and optional acid stabilizer.Products are suitable for Catalyst, battery electrolyte, beverage clarifier, fusing treatment agent, organic macromolecular modified materials, special coating and other industries.
Why is silica often chosen as a catalyst carrier?
The main advantage is that the chemical properties are relatively stable. It's an acid oxide. It doesn't react with normal acids. It does not interact with halogens, hydrogen halides, sulfuric acid, nitric acid, and perchloric acid (except hot concentrated phosphoric acid) other than fluoride and hydrogen fluoride. If it reacts with the catalyst, the catalyst will be poisoned. The phenomenon that the activity and selectivity of the catalyst are obviously decreased or lost due to the trace impurities in the reaction material. The essence of the poisoning phenomenon is a certain chemical reaction between trace impurities and the active center of the catalyst to form an inactive species.
Secondly, silica has the properties of good wear resistance, stable chemical properties and high melting point. Therefore, the catalyst carrier with it as the main mineral phase has stable performance.
And after the treatment of dioxy version of silicon has a very high specific surface area, strong adsorption, can increase the catalytic efficiency of the catalyst!
In general, silica carrier has great advantages on catalytic efficiency, catalytic activity, the firmness of catalyst load, service life, price and so on!
Gas phase silicon dioxide (white carbon black gas phase) is one of the important high-tech superfine inorganic new materials, due to its small particle size, specific surface area is big, therefore the surface adsorption power, surface energy, high chemical purity, good dispersion performance, heat resistance, resistance has specific performance, with its excellent stability, reinforcing, thickening and thixotropic, It is especially advantageous in catalyst support.
