Aluminum hydroxide powder is not only a functional material, but also provides a broad application prospect for the development of new materials. It plays an extremely important role in various fields of the national economy. With the ultra refinement of aluminum hydroxide, the surface electronic structure and crystal structure have changed, resulting in the surface effect and small size effect that block materials do not have, which makes it show unique performance in chemical activity, electricity, surface performance and other aspects, and has many special functions. Aluminum hydroxide vertical roller mill is used to process aluminum hydroxide superfine equipment. HCMilling(Guilin Hongcheng), as an aluminum hydroxide vertical roller mill manufacturer, will introduce the use of aluminum hydroxide powder as follows:

1. Aluminum hydroxide powder is used in the flame retardant industry: based on the fact that aluminum hydroxide absorbs a lot of heat when decomposing, and only emits water vapor when decomposing, without producing toxic, flammable or corrosive gases, aluminum hydroxide has become an important inorganic flame retardant filler. At present, the cyclic aliphatic epoxy resin added with aluminum hydroxide has been used in insulating materials, transformers and switchgear.

2. Aluminum hydroxide powder is used as filler for paper making: aluminum hydroxide is mainly used as surface coating, filler and incombustible paper production in paper making industry. In China, the application of aluminum hydroxide in the paper industry is less. With the development and production of ultra-fine aluminum hydroxide, the application of aluminum hydroxide in the paper industry will continue to increase. As a new type of coating pigment, aluminum hydroxide has many advantages compared with traditional pigments: high whiteness, fine particle size, good crystal shape, good compatibility with whitening agents, and good ink absorption. It can be used as pigment to improve the whiteness, opacity, smoothness and ink absorption of coated paper. It can be used in the production of high-grade paper such as newspaper, banknote paper, photographic paper and advanced dictionary paper.

3. Aluminum hydroxide powder should be used as a toothpaste friction agent: aluminum hydroxide is non-toxic and tasteless, with a Mohs hardness of 2.5-3.5 and moderate hardness. It is a good neutral friction agent. A toothpaste with good performance can be made by replacing chalk and dicalcium phosphate with aluminum hydroxide. The chemical inertia of aluminum hydroxide makes it easy to be compatible with other ingredients in toothpaste; At the same time, aluminum hydroxide is also widely used in medicated toothpastes and other high-grade toothpastes because of its good fluoride retention function.

4. Aluminum hydroxide powder is used in the pharmaceutical industry: aluminum hydroxide is one of the main components of stomach medicine. Aluminum gel is a traditional medicine for neutralizing stomach acid and treating stomach diseases. Aluminum chloride hexahydrate prepared from aluminum hydroxide can be used as coagulant in medicine and cosmetics.

5. Other uses of aluminum hydroxide powder: aluminum hydroxide and its specially processed calcined aluminum oxide have been widely used in chemical drugs, catalysts, plastics, coatings, ceramics, refractories, insulating materials, abrasives and other fields.

The particle size of aluminum hydroxide powder directly affects its flame retardancy and filling properties. With the particle size becoming smaller, the surface area of Al (OH) 3 particles increases continuously, which is conducive to the improvement of its flame retardancy. The finer the particle size, the higher the oxygen limiting index of the material. The physical and chemical properties test results of inorganic powder materials filled with polymer materials show that the ultra-fine inorganic rigid particles can toughen and strengthen the polymer materials. Therefore, the ultra-fine aluminum hydroxide particles can not only improve the flame retardancy of the system, but also solve the problem that they affect the mechanical properties. Because modern industry requires many solid materials to use powder as industrial raw materials, they should not only have extremely fine particle size, strict particle size distribution, and very low impurity content, but also have specific particle morphology with the development of ultra-fine powder application.

The aluminum hydroxide vertical roller mill produced by HCMilling(Guilin Hongcheng) is the ideal equipment for producing aluminum hydroxide powder, which can process 3-180μM Aluminum hydroxide powder. The finished calcium hydroxide produced by this equipment has many advantages, such as narrow particle size distribution, low impurity content, high whiteness, good particle shape, etc. If you have the demand for aluminum hydroxide powder production and processing, please contact us for details and provide follow information to us:
