The Use Of Sodium Aluminate

Sodium aluminate is a white amorphous crystalline powder. As a compound containing effective aluminum hydroxide, it is hygroscopic and easily soluble in water. It is an important industrial inorganic chemical product. In water treatment, it can be used as water purifier additive. Widely used in the purification of industrial water and tap water, it can reduce the hardness and turbidity of water, accelerate the settlement of suspended solids, and improve the separation conditions to accelerate the precipitation of hard ions. Sodium aluminate has a strong affinity for insoluble aluminum hydroxide , this property is used to treat boiler water in order to obtain very low silica impurity content and is also used in the manufacture of coagulant aids to improve the flocculation ability of clarified sewage with alum, ferric chloride and polymer media chemical reagents, the flocculation form Aluminum hydroxide can speed up the clarification process. In construction, mixed with water glass for plugging in construction, it can be used as cement quick-setting agent, which can make cement set quickly. It is an ideal additive for underground, fast construction, and cement that requires fast setting. The mixed use of aluminum sulfate in the papermaking industry is a good filler, which can improve the pressure characteristics, glue sinking and spacing control of new printing machines; in the papermaking process, it can play the role of quick-setting the pulp and is an alternative to gel New product; it can increase the whiteness of paper, make the surface of paper flat and smooth, and make it more fluent when writing; it can increase the weight of paper, increase the hardness of paper, and prevent paper from bleeding when writing.

In addition, it is also widely used in the production of textiles, printing and dyeing, pharmaceuticals, rubber, washing powder, and steel surface treatment. It is used as an inhibitor of alkali washing liquid for glass and ceramic engraving, to reduce the viscosity of oil well water and as a protective agent for steel surfaces. It can also be used as a soil hardener or used in industries such as soap and dyes. Silicate and crystallization of molecular sieve can be improved, it can be used as a catalyst and carrier for the conversion of petroleum hydrocarbons. It is an important raw material for the preparation of alumina adsorbents and catalysts, and its ability to react with silica can be used to produce adsorbents and catalysts with a wide range of uses - zeolite (molecular sieve). It can be used as a surface treatment agent in the production of high-grade white paint, and used as an additive in the process of polymerizing artificial fibers to improve coloring, antistatic and anti-pilling properties. This product is used in the production process of titanium dioxide to make its surface coated and improve its characteristics (extensive).
