What are the common applications of aluminum hydroxide do you know?
Aluminum hydroxide is a common alkaline substance, often seen in our lives, and widely used, such as aluminum hydroxide capsules, can neutralize excessive gastric acid secretion, is conducive to the link stomach pain and other phenomena.
aluminum hydroxideIs a common alkaline substances, often seen in our lives, and widely used, such as aluminum hydroxide capsules, can neutralize excessive gastric acid secretion, is conducive to the link stomach pain and other phenomena. In addition, aluminum hydroxide also has good performance advantages in some industrial fields, but in use, because of the material itself, it should be prepared for protection in production. So what are the common applications of aluminum hydroxide? Let's take a look.
1, aluminum hydroxide in strong alkali acid solution is relatively easy to decompose, heating decomposition dehydration into alumina, most suitable for application in glass steel, electronics, ceramics, glass products, etc.
2, the activity of aluminum hydroxide after a variety of additives cremation modified outer treatment, fineness, particle size layout is relatively small, flame retardant effect is also relatively good, can increase the amount of addition.
3, aluminum hydroxide can be used as a variety of aluminide materials, plastics, rubber and other flammable materials of flame retardant additives, artificial marble filler, artificial agate and other copper board paper coating and flame retardant paper supplement. The outer layer of copper board paper is smooth, particularly glossy, and has a relatively large adsorption of ink.

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.
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.
