What are the basic requirements for the use of magnesium hydroxide flame retardants?
It is increasingly recognized that the use of flame retardant materials is one of the strategic measures to prevent and reduce fire, and magnesium hydroxide flame retardant is a special chemical additive used to improve the combustion performance of combustible materials,
It is increasingly recognized that the use of flame retardant materials is one of the strategic measures to prevent and reduce fire,Magnesium hydroxideFlame retardant is a special chemical additive used to improve the combustion performance of combustible materials, which is widely used in the flame retardant processing of various decoration materials. The material processed by magnesium hydroxide flame retardant can effectively prevent, delay or terminate the spread of flame when attacked by external fire sources, so as to achieve the effect of flame retardant.
The flame retardant efficiency is high, and the dosage required to obtain the unit flame retardant efficiency is small. That is, the efficiency/price ratio is high. It is low-toxic or basically non-toxic, and the amount of toxic and corrosive gases and smoke generated during combustion is as small as possible, which is environmentally friendly. Good compatibility with the flame retardant substrate, not easy to migrate and exudation. The flame retardant material can be recycled and recycled.
Magnesium hydroxide flame retardant has high enough thermal stability, in the flame retardant substrate processing temperature does not decompose, but the decomposition temperature should not be too high, to 250~400 ℃ is appropriate. Not too much deterioration of the flame retardant substrate processing performance and product physical-mechanical properties and electrical properties. The excellent performance of magnesium hydroxide flame retardant and reasonable magnesium hydroxide flame retardant formula is to be able to achieve a harmonious unity between the flame retardancy and practicality of the material.

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.
