How are liquid flame retardant materials classified?
This is what we now need to know, in the life and safety quality awareness of people to be improved, which will enhance the awareness of fire prevention, and flame retardant requirements are also increasing, but the requirements of different substances on flame retardant materials are not the same, so we should choose the right flame retardant materials according to different industries.

classification of liquid flame retardant materials:
1, containing liquid flame retardant material. Due to the decomposition and release of hydrogen halide in the combustion process, hydrogen halide can capture the free radicals of the active group, thereby delaying or extinguishing the combustion of the material, so as to achieve the purpose of flame retardant. Commonly used PVC, neoprene, chlorosulfonated polyethylene, ethylene propylene rubber and other materials.
2. Low smoke and low halogen flame retardant materials. It is mainly used for polyvinyl chloride and chlorosulfonated polyethylene materials. By adding corresponding materials, it can improve flame retardant materials and reduce the emission of halogen acid mist and smoke, but the oxygen index can be slightly reduced. When the amount of additives is large, the mechanical and electrical properties of the material will be reduced.
3. Liquid flame retardant. Polyolefin is a halogen-free material, composed of hydrocarbons, which decompose carbon dioxide and water when burned, and will not produce obvious smoke and harmful gases. Polyolefins consist mainly of polyethylene and vinyl acetate. The material itself does not need to add flame retardants, inorganic flame retardants, phosphorus flame retardants, can be processed into halogen-free flame retardant materials, but practical, because non-polar substances on the hydrophobic group missing molecular chain, and inorganic flame retardants The affinity is poor, it is difficult to bond. In order to improve the surface activity of polyolefin, surfactant was added to the formula; the blending of polyolefin with polymer containing polar groups was studied to increase the filling amount of flame retardant, improve the mechanical properties and processing properties of the material, and obtain good flame retardancy.

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.
