Five steps of decomposition of magnesium hydroxide ingredients
Mention of magnesium hydroxide believe that everyone is very familiar, it is a colorless hexagonal column crystal or white powder, is widely used in many fields of industry. Some people consult the steps of magnesium hydroxide ingredients, so today magnesium hydroxide manufacturers to do a detailed introduction.

1. Magnesium hydroxide is made by calcining magnesite as the main raw material in a traditional carbonization kiln;
2. After filtering to remove impurities in iron hydroxide, soluble magnesium hydroxide is added, and brine with a concentration of 25% to 28 ammonia is added at the same time, and magnesium hydroxide is generated after dilution and pyrolysis for 1.5 hours;
3. making the above-mentioned magnesium oxide into a slurry material;
4. Put magnesium carbonate into an acid solution with a concentration of 98. After acidolysis into soluble magnesium hydroxide, add an oxidant with a weight ratio of 2% to 3 into the mixed acid solution to oxidize ferrous iron into ferric hydroxide;
5. Put the above slurry into the carbonization tower to carbonize and reduce the slurry into magnesium carbonate.

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.
