Current Market Analysis and Application Effect of Magnesium Hydroxide

Higher grade villas abroad, the wall materials are to add magnesium hydroxide, heat insulation effect is better. Many airports and large supermarkets also use magnesium hydroxide flame retardant materials on the roofs to keep warm in winter and heat in summer. The amount of foreign use is very large, but at present this material is not used much in our country. According to reports, the current raw materials used to extract magnesium hydroxide are mainly brucite ore. A large number of brucite mines in China are mainly in the Dandong region of the northeast, while the purity of magnesium hydroxide in the raw ore is only 95%, which can only be used as a low-end flame retardant, such as materials for subway seats and carriages. In higher grade spacer materials, hydrogen oxidation

According to reports, the current raw materials used to extract magnesium hydroxide are mainly brucite ore. A large number of brucite mines in China are mainly in the Dandong region of the northeast, while the purity of magnesium hydroxide in the raw ore is only 95%, which can only be used as a low-end flame retardant, such as materials for subway seats and carriages. In the higher grade edge materials, the purity of magnesium hydroxide must reach more than 99% to meet the requirements. Taking the optical fiber as an example, the diameter of the core and the cladding of the optical fiber are both micron-sized, which is equivalent to that of human hair, and has higher requirements for tensile strength and processing performance. Therefore, it is necessary to realize the magnesium hydroxide flame retardant Strict control of the morphology, particle size and other parameters.

What kind of products meet the requirements of high-grade magnesium hydroxide flame retardant products? Simply put, only by achieving accurate control of the five parameters of morphology, particle size, particle size, purity and whiteness, can we make high-grade products compared with foreign products.

At present, the high-grade magnesium hydroxide flame retardant market is still mainly monopolized by 5 manufacturers from the United States, Japan, and Israel. The value of each ton of products ranges from 24000 yuan to 37000 yuan. However, after years of efforts, we have successfully mastered the key process of preparing magnesium hydroxide flame retardant products, and are gradually breaking the situation that high-grade magnesium hydroxide flame retardants are monopolized by foreign manufacturers.

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.
