Aluminum hydroxide has multiple usages such as flame retardant, smoke suppression and filling, and it can produce a synergistic flame retardant effect with various substances. It has become an important environmentally friendly flame retardant in industries such as electronics, transportation, plastics and rubber. With the development of the emerging material industry and the improvement of environmental protection requirements, its usage and application range are getting larger and larger, and more stringent requirements are put forward on product quality and performance.
application:
1. Chemical raw materials: Because aluminum hydroxide can be produced on a large scale, the raw materials are sufficient, the product purity is high, and it is easily soluble in acid and alkali. Therefore, aluminum hydroxide is an important raw material for preparing aluminum salts, such as barium aluminate and aluminum sulfate.
2. Flame retardant: Aluminum hydroxide powder is usually regarded as an ideal raw material for plastics, unsaturated polyester, rubber and other organic polymers because of its filling, flame retardant, smoke suppressing functions and non-toxic and harmless.
3. Ceramics: Aluminum hydroxide is calcined at high temperature to obtain alumina. Alumina has high thermochemical stability, thermal strength, creep resistance, dielectric properties and low thermal expansion coefficient, and is an important material for synthetic porcelain . In the ceramic synthesis process, aluminum hydroxide activates and controls the crystallization process, so as to control the phase formation of the composite material.
4. Sewage treatment: Aluminum hydroxide is mainly Al(OH)4- in the water, which can precipitate the toxic heavy metals in the sewage by co-precipitation and then filter to achieve the effect of water purification. Aluminum hydroxide also has a very high specific surface area, which can adsorb colloids, suspended solids, dyes, organics, etc. in the sewage on the surface.
5. Paper industry: Aluminum hydroxide has high whiteness, ultra-fine particle size, complete crystal form, and has strong compatibility with Whitening agent. Using it as an additive for coatings and resins can effectively improve the whiteness, opacity, smoothness and inking properties of coated paper.
