Brucite is the richest mineral magnesium in nature, is the most effective source of magnesium metal raw materials, has become the current development of magnesium in the world the important object of raw material, therefore, to research and find water magnesium ore is of great significance to the development of modern industry.
With the progress of the development of the society and industry, the mineral resources utilization in human increasingly widespread, some didn't widely used non-metallic mineral also got more attention and research, brucite is one of them. As a kind of mineral as early as 1919 by mineralogist understanding, then to its composition, structure, physical and chemical properties and so on various aspects to do a lot of research. In the former Soviet union in the far east geological survey found later, truly, as a kind of industrial minerals development and utilization of them.
Add flame retardant agent was added to the polymer by mechanical mixing method, the polymer with flame retardancy,Brucite small make up is introduced the additive flame retardants mainly include organic flame retardants and inorganic flame retardants, phosphorus-containing flame retardants (organic chloride and bromide) and non halogen. Organic bromine, phosphorus and nitrogen, nitrogen compounds and red phosphorus and represented some of the flame retardant, inorganic mainly antimony trioxide, aluminum hydroxide, magnesium hydroxide, such as silicone flame retardant system.
Magnesium salt production process due to different raw material, energy consumption is different; The same kind of raw material route due to different equipment, related to energy consumption is larger, but no matter what raw material route, because of the filter cake water high, dry energy-consuming, generally about 30% ~ 60% energy consumption accounts for the cost.
The current domestic aluminum hydroxide dosage is more, but with the increase of temperature of the polymer processing, aluminum hydroxide is easy to decompose, reducing flame retardant effect, he's better than aluminum hydroxide has the following advantages.
