What are the powerful functions of aluminum hydroxide?
Aluminum hydroxide is a hydroxide of aluminum. This alkaline chemical substance has many excellent characteristics and can be used in many different environments. In modern industry, aluminum hydroxide is used as a very good flame retardant.
Aluminum hydroxide is a hydroxide of aluminum. This alkaline chemical substance has many excellent characteristics and can be used in many different environments. In modern industry, aluminum hydroxide is used as a very good flame retardant. below to introducealuminum hydroxideIntrinsic characteristics.
1. adsorption: aluminum hydroxide crystal has a hole structure, and the specific surface area is very large, so its adsorption capacity is very strong, beyond a lot of chemical substances with adsorption. The addition of more surfactants in the production of highly concentrated washing powder by agglomeration will make the product more effective.
2. Anti-redeposition: aluminum hydroxide has good oil adhesion, when sodium carbonate, CMC, sodium silicate and sodium sulfate additives such as zeolite, will greatly reduce the adsorption of nylon cloth to oil. When the particle size of zeolite is 0.4-1.0μm, the dispersion is good and the adhesion on the fabric can be prevented.
3.PH buffering effect: aluminum hydroxide is alkaline, and the pH of 1% aqueous solution is 11.0, so it has a certain buffer alkalinity.
4. Safety: When using aluminum hydroxide, there is no need to worry about its adverse effects on the human body and the environment, so there is no need to worry about this.
5. Softening water quality: the internal structure of aluminum hydroxide determines that it can play an ideal function of softening water quality. Using this principle, aluminum hydroxide can be added to the solution containing heavy metals. After a period of time, the water quality will be purified.
6. Detergency: Through experiments on the same formula containing different additives, the detergency of the additives is changed and compared. It is found that the detergency effect of 20% STPP, 20% molecular sieve and 4% polymer is equivalent to that of 40% STPP. A product with ideal detergency can be obtained by adding 10% sodium carbonate and 4.5 polymer to 20% molecular sieve in phosphorus-free formula.
Aluminum hydroxide is also known as aluminate because of its acidity. However, the actual reaction with alkali is the formation of four hydroxy aluminate. Therefore, it is usually regarded as monohydrated metaaluminic acid (HAlO2 · H2O), which is divided into industrial grade and pharmaceutical grade according to its application.

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.
