What is the difference between aluminum hydroxide and aluminum oxide?

Aluminum hydroxide is made of bauxite, which is processed by a special process to obtain raw materials, and then calcined to obtain alumina. Therefore, the amount of raw materials here is the same, which is a different link in the same production process, so what are the differences between the two?

　 aluminum hydroxideIs the use of bauxite, through a special process to obtain raw materials, and then calcined to obtain alumina. Therefore, the amount of raw materials here is the same, which is a different link in the same production process, so what are the differences between the two?

Below we mainly from the physical properties and chemical properties of two aspects to understand the difference between them:
1, physical properties: alumina is white, insoluble in water solid, high melting point. Aluminum hydroxide is a white colloidal substance, insoluble in water, and strong adsorption, can be adsorbed in water suspended solids and various pigments.
2, chemical properties: alumina is a typical amphoteric oxide, does not react with water, and acid, alkali can react; aluminum hydroxide chemical properties are not stable, heat easily decomposed, insoluble in weak acid, weak base, and dissolved in strong acid, strong base, commonly used to identify Al(OH)3.
3, use: alumina is mainly used for high temperature refractory materials; and aluminum hydroxide in a variety of fuel industry and medicine have a very good role.
Aluminum hydroxide and alumina are different in many aspects, so when choosing a product, you only need to buy the corresponding product according to the industry to be used.

Zhongke Flame Retardant Organization Watches 20 Closing Ceremonies

On the morning of October 22, 2022, members of Zhongke Flame Retardant New Materials Co., Ltd. watched the closing ceremony of the 20th Congress under the leadership of General Manager Wang Ligui.

What are the reasons for the failure of flame retardant after adding aluminum hydroxide flame retardant?

Everyone knows that there are two common flame retardants. Today we are going to talk about only one of them. Aluminum hydroxide flame retardant is an environmentally friendly halogen-free flame retardant, which can be widely used in fabrics, wood, plastics, and rubber., Polyurethane and other industries have ideal flame retardant effect. In the process of industrial application, it is found that flame retardant failure occurs when aluminum hydroxide flame retardant is added. The following are the reasons for the failure of aluminum hydroxide flame retardant, how to prevent it, how to deal with the operation, and restore the original function.

As a flame retardant, magnesium hydroxide also need to improve what aspects?

When it comes to flame retardants, everyone is familiar with them. Although we usually have less contact with them, we can know what they are used for from the name. Have to talk about magnesium hydroxide, we all know that its main presentation state is a granular, at present, the market sales of magnesium hydroxide particle size is larger, part of the commodity particle size up to tens of microns, immediately used as a flame retardant, poor dispersion, the physical properties of raw materials greater harm. In industrial production, physical grinding methods are generally used to reduce the particle size to 1 micron. The surface of magnesium hydroxide has high polarity and is easy to agglomerate. As the compatibility of refractory materials and polymer substrates, it not only reduces its flame retardant grade, but also causes more serious harm to the physical properties of raw materials.
