Product Description

The chemical properties are transparent or translucent tiny particles with a multi-microporous structure, high specific surface area, high mechanical strength, and high silica content. Non-toxic, odorless. Good thermal stability, good acid resistance (except hydrofluoric acid). Soluble in caustic soda. It has a strong adsorption effect on water vapor and other gases and solvents. Use as catalyst carrier for important petrochemical products such as phthalic anhydride, aniline, maleic anhydride, melamine, butadiene rubber and acrylonitrile. It is also widely used for refining petrochemical products, removing aromatics, selective adsorption separation of some organic gases and liquids. It can also be used as an ion exchanger to remove polyvalent harmful elements from water. It is also used for dry storage of materials, instruments and other items and dewatering and refining of high purity gas. The purpose of filtration is mainly used as a liquid adsorbent, desiccant and spice carrier, and can also be used as a catalyst carrier to be used as a dehumidifying desiccant, dehydrating agent, moisture-proof agent and air humidity regulator. Also used for gas drying. It is also used as catalyst and catalyst body, reinforcing agent of silicone rubber, and sizing agent used in textile industry. Use as a hygroscopic agent, its color changes from blue to red with the growth of hygroscopic amount to show the change in the humidity of the space medium of the sealed package. Use instead of ethyl silicate for precision casting, in order to reduce production costs, improve the operating environment, and improve product quality. Used as a adhesive for refractories and other materials. It is a coating material that prevents the oxidation of certain products. As a coating material (internal and external waterborne wall coatings) to improve bonding, fastness, wear resistance, pollution resistance. As a synthetic fiber treatment agent to improve the friction coefficient of the fiber. As a warp sizing agent in woolen spinning industry, it can improve spinnability, handiness, reduce flying hair and broken head, and increase production. Used in paper industry to improve paper smoothness and paper strength. It is also used as an abrasive and catalyst for finishing electronic materials, and a coagulant for sulfuric acid in batteries. The dilute water glass is filtered by ion exchange method to remove impurities after cation exchange, anion exchange, Ph value adjustment, evaporation or ultrafiltration concentration, silica sol is prepared. Silica powder method adds distilled water and sodium hydroxide (reagent grade) to the reaction tank, heating up to 65ºC, adding a certain amount of ammonia water to adjust the alkalinity, adding silica powder in batches under agitation, controlling the temperature below 83ºC, after adding silica powder continue to stir for 2 ~ 3h, when the Ph value drops to 9 ~ 10, sampling and analysis, after the reaction is completed, it is cooled to 50ºC under agitation, and then filtered naturally. Silica sol product was prepared. The unreacted silica powder can be recovered and reused. The silica gel is prepared by sulfuric acid method by mixing diluted water glass with dilute sulfuric acid at 20 ~ 30ºC, aging for 4h, soaking lh with 2% ~ 2.5% dilute sulfuric acid, washing in water at 40 ~ 50ºC, dewatering in a rotary dryer until the water content is less than 80%, drying until the water content is less than 10%, and activating in an activation furnace at 500 ~ 550ºC. The coarse pore microspheres were prepared by screening.
