Advantages of 1. aluminum hydroxide flame retardant

　　aluminum hydroxideFlame retardant will not cause secondary pollution when burning, and will not produce toxic gases and corrosive gases when discharging. It has the effect of absorbing heat, can also release water vapor, and has flame retardant self-extinguishing properties. It has good dispersion in polyolefin, and other added substances are easy to produce flame retardant effect. In addition, due to the existence of crystal water, polymer products also have a certain antistatic effect, which can improve and enhance the strength and toughness of high molecular polymers.

Product Features of 2. Aluminum Hydroxide Flame Retardant

1, has a very high quality flame retardant smoke suppression performance

Because it is decomposed by thermal dehydration, after dehydration, A1203 protective film can be generated on the surface of combustible materials to isolate oxygen. As a result, the concentration of combustible gas and oxygen will decrease, which will very well inhibit the temperature rise and thermal degradation of polymers, inhibit the generation of flue gas through adsorption, and carbonize it. It cannot produce combustible volatiles and can prevent combustion, it is very suitable for processing composite materials with molding temperature below 200 ℃.

2, has very good insulation performance

Fluidized purification process greatly reduces the content of iron, sodium, potassium and other impurity ions.

3, the characteristics of high whiteness

Does not interfere with the dyeing of composite products.

4, contains relatively low iron

The content is less than double zero five (I. e. 0.005%).

5, contains relatively low sodium

The content is below 0.15.

Through the above analysis, we should knowaluminum hydroxideThe characteristics of flame retardants, in addition, but also to understand its preparation methods, including hydrothermal synthesis, carbon method, liquid phase co-precipitation method, high gravity reaction precipitation method. I hope everyone can do their homework well and have a comprehensive understanding of relevant knowledge so as to apply it well.

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.
