What are the chemical properties of magnesium hydroxide?

The chemical properties of magnesium hydroxide are: white crystals or powder. The aqueous solution is alkaline. 2.36g/cm3. Soluble in dilute acid and ammonium salt solution, basically insoluble in water and alcohol. The solubility in water (18°C) is 0.0009g/100g. Easy to absorb carbon dioxide in the air. When heated to above 200 ° C in an alkaline solution, it becomes a hexagonal crystal system. Decomposition at 350°C to form magnesium oxide and water. Above 500 ℃, the loss of water is transformed into magnesium oxide. Magnesium carbonate in boiling water can be converted into magnesium hydroxide, which is less soluble. Magnesium hydroxide is commonly used in PE,PP,PVC,ABS,PS,H

Magnesium hydroxide is widely used in PE,PP,PVC,ABS,PS,HIPS,PA,PBT, unsaturated polyester, epoxy resin, rubber, flame retardant filler for paint, chemical industry, environmental protection and other industrial fields. Excellent flame retardant and filler for polymer materials such as plastics and rubber, as flue gas desulfurizer in environmental protection, can replace caustic soda and lime as neutralizing agent for acid-containing wastewater; Used as oil additive for anticorrosion and desulfurization; used in the electronics industry, medicine, sugar refining; used in insulation materials and the manufacture of other magnesium salt products.

What kind of products meet the requirements of 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 good products compared with imported products.

At present, the magnesium hydroxide flame retardant market is still mainly controlled 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, China has successfully mastered the key process of preparing magnesium hydroxide flame retardant products, and is gradually breaking the situation that magnesium hydroxide flame retardant is controlled 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.
