Two categories of magnesium hydroxide flame retardant

Magnesium hydroxide flame retardant according to the chemical composition can be divided into organic flame retardant and inorganic flame retardant two categories. Organic flame retardants are divided into two series of phosphorus and halogen. Because organic flame retardants have the disadvantages of high toxicity and smoke, inorganic flame retardants are more and more widely used.

The main varieties of inorganic flame retardants are aluminum hydroxide, magnesium hydroxide, red phosphorus, antimony oxide, tin oxide, molybdenum oxide, ammonium molybdate, zinc borate, etc. Among them, aluminum hydroxide and magnesium hydroxide can isolate air due to large amount of heat absorption in decomposition and H2O generation. The decomposed oxides are high-temperature resistant substances, so the two flame retardants can not only play a flame retardant role, but also play a filling role, it has no corrosive halogen and harmful gases, non-volatile, long-lasting effect, non-toxic, smokeless, not dripping and so on.

The above is the classification of magnesium hydroxide flame retardant, at the same time we are a professional magnesium hydroxide flame retardant production company, if you have demand for our magnesium hydroxide flame retardant, welcome to contact us.

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.
