The flame retardant has enough high thermal stability
2021-07-16 14:36:34

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 flammable materials, which is widely used in the flame-retardant processing of various decoration materials. The material processed by flame retardant can effectively prevent, delay or terminate the spread of flame when attacked by external fire source, so as to achieve the effect of flame retardant.


Flame retardant


The flame retardant efficiency is high, and the amount needed 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. The amount of toxic and corrosive gas and smoke generated during combustion is as small as possible, which is friendly to the environment. It has good compatibility with the flame retardant substrate, and is not easy to migrate and exudate. The flame retardant materials can be recycled and recycled.

The flame retardant has enough 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, and it is appropriate to be between 250 ℃ and 400 ℃. The processing performance of the flame retardant substrate and the physical mechanical and electrical properties of the final product will not be deteriorated. Excellent flame retardants and reasonable formulation of flame retardants can achieve a harmonious unity between flame retardancy and practicability of materials.

Aluminum hydroxide around our lives can be said to be more common, its application is also very wide. Have you ever known about hydrogen peroxide? It is an inorganic compound and is generally used for disinfection. You know what application aluminum hydroxide filler has in hydrogen peroxide auxiliary agent? Are you curious?

Aluminum hydroxide filler has the characteristics of low wear, less floating powder, large specific surface area and strong regeneration ability, so it has become an ideal auxiliary product in the hydrogen peroxide industry. Compared with ordinary activated alumina ball desiccant, although the process of raw materials is basically the same, the processing requirements are still quite different.

Aluminum hydroxide filler for hydrogen peroxide production is also a white spherical porous material; It is nontoxic, odorless, tasteless, insoluble in water, ester, hydrocarbon, alcohol and other organic solvents, and has the characteristics of no pulverization in water and alkali, no softening, high clarity and long service life. In the process of hydrogen peroxide production, it has the advantages of strong degradation and regeneration ability of anthraquinone derivatives in the working solution. It is a special adsorbent for hydrogen peroxide production by anthraquinone method. Activated alumina is used to regenerate the degradation products of working solution in the production of hydrogen peroxide by anthraquinone method, especially in the production unit of palladium catalyst and three component nickel catalyst. At present, there is no ideal method to regenerate the working solution, which mainly depends on activated alumina. In addition to adsorbing the alkali in the working solution of hydrogen peroxide production, it also has strong regeneration ability for the hydrogenated degradation products of the working solution.
