What are the basic requirements for flame retardants?


 
It is increasingly recognized that the use of flame retardant materials is one of the strategic measures to prevent and reduce fire. It is a special chemical additive used to improve the combustion performance of combustible materials and is widely used in the flame retardant processing of various decoration materials. After the flame retardant processing of the material, in the external fire attack, can effectively prevent, delay or terminate the spread of the flame, so as to achieve the role 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.
The flame retardant has sufficiently high thermal stability and does not decompose at the processing temperature of the flame retardant substrate, but the decomposition temperature should not be too high, preferably between 250 and 400 ℃. It will not deteriorate too much the processability of the flame retardant substrate and the physical-mechanical and electrical properties of the final product. The flame retardant with excellent performance and reasonable flame retardant formula are the harmonious unity between flame retardancy and practicability 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.

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.
