What are the functions of high white aluminum hydroxide?
As we all know, high white aluminum hydroxide has high whiteness and good fluidity, its particle size distribution is also very uniform, and it also has the characteristics of high added value. It is well known and applied by more and more people in all walks of life. Next for everyone to introduce the function of high white aluminum hydroxide:
As we all know, high whitealuminum hydroxideHigh whiteness, and good fluidity, its particle size distribution is also very uniform, but also has the characteristics of high added value, in all walks of life, is more and more people are familiar with and application. Next for everyone to introduce the function of high white aluminum hydroxide:
High-white aluminum hydroxide is a kind of amphoteric compound, but it has poor compatibility with organic polymers, especially the wrong polar polyolefin, and the interfacial bonding force is relatively small, which is easy to cause when it is used as a flame retardant filler, resulting in the function of fitting data processing and the decrease of mechanical function.
However, for high-white aluminum hydroxide with ultrafine particle size, when it enhances the mutual effect between interfaces, it can be more evenly dispersed in the fundamental resin, effectively improving a mechanical function of the blend.
We know that when high white aluminum hydroxide is used as a filler to fill epoxy resin, it will increase the strength of epoxy resin. At the same time, its oxygen index will also increase significantly, which can be improved from 20.0 to 27.5. It is mainly used for sealing materials, casting parts, and epoxy resin glass fiber sheets.
In electrical appliances, high white aluminum hydroxide is widely used as a filler. Now, the cyclic aliphatic epoxy resin of aluminum hydroxide is also added, which can be better used in insulation materials, transformers and switchgear.
In modern industry, solid materials are required to be used as industrial raw materials in the form of powder, which requires them not only to have extremely fine particle size, but also to have strict particle size distribution and extremely low impurity content. At the same time as the wide application and development of high white aluminum hydroxide, there is a need for specific particle tracing. This involves a close relationship between particle tracing and physical properties.
They will have an impact on the mobility, filling and chemical activity of the particle group, and many properties. With the addition of high white aluminum hydroxide, many objects will have anti-leakage ability, and their arc resistance and wear resistance will be enhanced.

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.
