Application Status and Development Trend of magnesium hydroxide forecast

With the development of polymer materials, polymer materials, flammable increasingly people's attention, the demand for flame retardants increases. However, environmental factors such as people made more stringent requirements, non-halogenated flame-retardant, high efficiency, smoke suppression, non-toxic become the development trend in the future. Hong Taiji is a research and development, production and sales of high-tech industrial company, engaged in new materials and ultra-fine powders and surface modification technology research, development, production and technical services and consulting business. Hong Taiji has a number of domestic and foreign experts and professors of prestigious and experienced professional and technical personnel, the company in the development of new products, take advantage of its own conditions and regional advantages, always positioned to colleges and universities, supplemented by independent research and development-oriented policies. At present, the company R & D team developed and industrialized mass production of the new green filling flame retardants (The product in 1994 through the identification), the composite type flame retardant, flame retardant and smoke suppressant, and other non-metallic mineral products, complete specifications, strong technical force, advanced process equipment, product quality, especially magnesium hydroxide flame retardants, is the company's flagship product, since the market, due to the excellent flame retardant properties by the majority of users of praise , products have broad market prospects.

1. magnesium hydroxide flame retardants main application areas: Currently, the macro Taiji magnesium hydroxide flame retardant is a novel filled in recent years, the company's own research and development, it is widely used in rubber, chemicals, building materials, plastics (polypropylene, polyethylene, polyvinyl chloride, EPDM, etc.) as well as electronic, unsaturated resin and paint, coatings and other polymer materials, especially for mining duct, PVC entire core transport belt, fire-retardant blanket, fire-retardant aluminum panels, fire retardant tarpaulins, PVC wire and cable, mining cable sheathing, flame retardant cable accessories, smoke, anti-static; can replace aluminum hydroxide, with good retardant effect. Hong Taiji magnesium hydroxide flame retardants have large-scale production of a number of production lines, mainly produces a variety of specifications: Normal, superfine and after surface modification of magnesium hydroxide flame retardants, the total output of nearly 10,000 tons of special ultrafine magnesium hydroxide flame retardants because of a variety of brand specifications and product quality and cheap, to meet the different needs of customers, the majority of customers.

2. magnesium hydroxide flame retardant mechanism: the thermal decomposition temperature of macro Taiji Industrial Development magnesium hydroxide high initial temperature of 340 ℃ -490 ℃ when the complete decomposition, thermal decomposition, because of its high decomposition temperature range wide and the total heat of 44.8KJ / mol, are higher than other inorganic flame retardants, it is a good flame-retardant effect. Its flame retardant mechanism is under heated conditions, you can use the following reaction formula: Mg (OH) 2-MgO + H2O-Q, from the point of view of flame retardant reactive polymer releasing decomposition when heated crystal water, while absorbing large quantities of latent heat, thereby suppressing the temperature rise in the flame retardant polymer, thereby delaying the thermal decomposition of the polymer and reducing the combustion speed; released during the decomposition of crystal water becomes steam at a higher temperature, lower burning to prevent the concentration of the polymer surface, a certain degree of oxygen near the surface of the polymer and the combustible gas; secondly, magnesium hydroxide, but also in the carbonized layer polymer surface to prevent entry of oxygen and heat; and decomposition products formed also MgO Good refractories, improve the ability of the polymer material to resist flame, played isolated from the air to prevent combustion purposes. Because magnesium hydroxide has more than a few properties in the heating process, so the effect of magnesium is ideal inorganic flame retardants, it will be expanding application areas.

3. Development Status of magnesium hydroxide flame retardants: In the domestic application of magnesium hydroxide as a flame retardant late start, the level of awareness and lack of publicity, a lot of the chemical industry, for example: rubber, plastics and other industries not yet widely used, while the sales price It is also an important factor in its application and development impact. For other countries, like the United States, Japan and Western Europe and other countries, the annual amount of magnesium hydroxide flame retardant to maintain a high growth rate, such a short period of continued growth will not change much, and then also from the side The reaction of the country as a result of production, application of polymers country, the development prospects of halogen-free magnesium hydroxide is broad. Hong Taiji Industrial Co., took a fancy to magnesium hydroxide broad prospects for development, and magnesium hydroxide-based flame retardant mechanism, for some particularly high requirements for flame retardant industry, often need to add a high amount of features, such The resulting product performance has been greatly affected. Physical and mechanical properties and processing performance, are difficult to achieve the desired requirements; to this end, Hong Taiji Industry through its own research and development, trial and error, for surface modification, and ultimately developed the ideal product; main product specifications They are: ultra-fine, surface modification process type, synergistic complex of magnesium hydroxide flame retardants and other specifications, to meet the different levels of flame retardant products, to better meet the needs of the market.

The magnesium hydroxide surface modification technology: in a market economy and society, in order to better meet the needs of industry market, macro Taiji Industry R & D team through united efforts to develop good flame retardant effect, a variety of magnesium hydroxide flame retardants and use a lot of the industry's products has achieved good results. Hong Taiji Industrial use of foreign advanced equipment, technology, research of flame retardant powder surface modification of magnesium hydroxide flame retardant materials for the ultra-fine powder, surface modification method, microencapsulation method, coupling method, a synergistic composite method, etc., surface modification, full use of the advantages of the various methods, and then add different industries with different little material, can achieve different flame retardant effect of making more targeted and selective flame retardant, but also for the company to stabilize the market and open up the market to provide a solid foundation.
