What is the future development prospect of magnesium hydroxide flame retardant?
Nowadays, many companies use magnesium hydroxide flame retardants, which can fully protect the company's assets and personnel from damage in the event of a fire. It is precisely because of this, so that the flame retardant in the Chinese industry has gained greater attention, then, the future development prospects of magnesium hydroxide flame retardant.
01
How to choose magnesium hydroxide flame retardant, these points to consider!
The use of magnesium hydroxide flame retardants in the major chemical industries is still very extensive, so the demand for magnesium hydroxide flame retardants will be relatively increased with the increase in production. Especially for some large enterprises and chemical plants, there is a great demand for excellent flame retardants. Therefore, as a new type of flame retardant, magnesium hydroxide has a very good market prospect. Therefore, many manufacturers have begun to produce magnesium hydroxide. So, how should we choose when purchasing magnesium hydroxide flame retardant, especially in the face of many manufacturers, how should we buy it?

What are the advantages of magnesium hydroxide as a flame retardant
Magnesium hydroxide is a new type of flame retardant, which has replaced the traditional caustic soda and lime and other flame retardants such as aluminum hydroxide and aluminum oxide in the field of flame retardant in the chemical industry. And magnesium hydroxide is mainly used in some environmentally friendly materials, such as plastic, rubber and other materials. In addition, magnesium hydroxide can also be used in some other industries such as the pharmaceutical industry and daily chemical industry, so what are the specific advantages of magnesium hydroxide when it is used to make flame retardants.
28
What are the precautions for the use of magnesium hydroxide?
Magnesium hydroxide is a new type of flame retardant, and also has a greater contribution to environmental protection, that is, it can be used as a flue gas desulfurization agent. Especially in some rubber products and plastic products by reducing the surface temperature, can have a very good flame retardant effect. As a chemical material, magnesium hydroxide also needs to be paid attention to in the process of use, so as to avoid harm caused by illegal use and operation. Here are some points for attention to tell you what should be paid attention to in the process of using magnesium hydroxide.

Rising market demand for flame retardants
Flame retardant materials are widely used, especially for high-rise buildings, flame retardant materials play an important role in preventing or reducing the loss caused by fire. There are many kinds of flame retardant materials, which can be divided into organic flame retardant materials, inorganic flame retardant materials and organic inorganic composite flame retardant materials. At present, most of the flame retardant materials used in flame retardants are materials that can achieve flame retardant effect after adding flame retardants to polymer materials.

The actual effect of asphalt flame retardant
In recent decades, with the continuous progress of science and technology in China, asphalt, as a basic building raw material, its application technology and application fields are also developing. But the inherent flammability of asphalt makes it easy to ignite at high temperatures, accompanied by a lot of smoke and heat, which is extremely dangerous. Therefore, it is necessary to use asphalt flame retardants. So, what is the role of asphalt flame retardant?

Storage Method of Aluminum Hydroxide Flame Retardant
As a chemical product, aluminum hydroxide flame retardant has certain risks. Therefore, for chemical products, care must be taken when storing, otherwise a little storage error will not only cause it to reduce or lose its own performance, but also more likely to cause risks. Therefore, when storing such substances, they must be stored in strict accordance with the relevant regulations.

How are flame retardants used?
Polymer incineration is a very intense and complex thermal oxidation reaction, with smoke or flame characteristics. Flame retardants are additives that prevent plastics from burning or suppressing flame transmission. The flame retardant effect of the flame retardant is to block or suppress the physical or chemical changes in the polymer incineration process. The flame retardant effect of flame retardant in the process of polymer incineration, flame retardant endothermic effect and endothermic effect make the temperature of polymer materials difficult to rise.

Flame retardant effect of aluminum hydroxide in PVC
The phenomenon of continuous combustion of polymers actually requires relevant composition factors. That is: dye, heat and oxygen. The burning of the three missing is over. Black and white smoke is usually different from the smoke from burning plastic. Black smoke refers to the solid particles suspended in the combustion gas product under anoxic conditions; white smoke refers to small particles suspended in the air, such as steam condensate. Aluminum hydroxide flame retardant has a certain smoke suppression effect on soft polyvinyl chloride, but the mechanism of black smoke has a representative carbon double bond shrinkage mechanism, that is, gas polymerization to produce aromatic or polycyclic polymer compounds, and then shrink graphitization to produce carbon particles.
