How to treat the application of aluminum hydroxide in flame retardant
Aluminum hydroxide can not only react with acid to generate salt and water, but also react with strong alkali to generate salt and water, which is a kind of amphoteric hydroxide. Therefore, it is widely used and multi-purpose. So its role is mainly manifested in what aspects, let's take a look at it.

1. Aluminum hydroxide colloidal solution has great adsorption capacity, can adsorb color or combine with it, so that the color is fixed to cotton yarn fiber, and is used as a mordant in the dye industry;
2, used to manufacture all kinds of flame retardant, waterproof fabric, ink, glassware, paper filler, roller skidding agent and other supplies;
3. Medicinal aluminum hydroxide is an antacid with a long history. It can resist acid, absorb, stop bleeding locally and protect ulcer surface. Its effect is slow and lasting, but its effect is weak. Commonly used as a drug to neutralize gastric acid, it is the active ingredient of weishuping;
4. Aluminum hydroxide is used as a water purifying agent because it can cement the turbidity in water and precipitate.
5, aluminum hydroxide as a flame retardant can not only flame retardant, but also can prevent smoke, do not produce dripping, do not produce toxic gases.
The above is about the role of aluminum hydroxide is introduced, after understanding, we can choose it correctly.

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.
