The applications and classifications of magnesium hydroxide
The applications of magnesium hydroxide mainly fall into three categories : one is widely used in environmental protection, neutralizing the acid waste-water, exhaust fume and de-sulfuration, removal of heavy metals from waste-water, decoloration of printing and dyeing waste-water. The second is used as polymer filling and flame retardant, which is only second to aluminum hydroxide. Its decomposition temperature is 340, and very suitable for high processing temperature of polymer PA, PC, PMMA, PP and parts of ABS, PS, PE, EVA, etc. Due to the requirements of manufacturing automobile are smaller diameter wire, cable and the lower volume of the equipment, we often turn to choose magnesium hydroxide as fire retardant. The third is used as raw materials of other magnesium compounds.
Because magnesium hydroxide is belong to middle-strong alkali, and it has a stimulus to eyes, respiratory system and skin. So we should make appropriate protection like wearing gloves or goggles when using it. If contacting with eyes carelessly, please rinse with plenty of water immediately and seek the doctor’s advices.
In 2006, America consumption of magnesium hydroxide is 221 kt/a, from 2006 to 2015 is expected to increase by 5% ~ 6% every year, in which 60% are used in environmental protection, including the governance of 90% waste water pollution and 10% air pollution; 60% of them are used in production of magnesium chemicals; 9% are used in flame retardant; 5% used in paper and pulp; 10% are used in pharmaceutical grade product and others.

The applications of magnesium sulfate
1、Chemical materials : It is used as refractory material, additive and the raw materials of magnesium oxide, magnesium, magnesium hydroxide and magnesium carbonate, etc.
2、Medicine : The substitute of drain the salt and low sodium salt; prevent herbivores from cramp disease caused by the lack of magnesium and prevent the buffalo from infertility.
3、Building materials industry : Used as adiabatic and soundproof fireproofing materials; manufacture cement of anti-freezing and waterproof.
4、Foundry industry : make water-soluble mold; used for aluminum alloy, copper alloy, cast iron and other precision casting .
5、"Three wastes" treatment : Used for industrial waste, dust, thermal power plants of city garbage sealing dust curing materials; oily wastewater treatment.
6、Heat storage material : Used for absorbing solar energy and industrial waste heat, cool storage material of extra electricity.
7、Resin plastic industry : Used as coagulant, fire retardant, additive.
8、Textile Dyeing Auxiliary : Used for dyeing and printing regulator of cotton and wool products.
9、Soil improvement : Used as seepage prevention agent in reforming sandy soil.
10、Others : used in paper making, tanning, electroplating, cigarettes, fertilizers, explosives, matches, agricultural chemicals, fibers, pigment, solvent, refrigerant, desiccant, etc.

Magnesium oxide for magnetic materials
Speaking of magnetic materials , many people rarely heard . If we enumerate its applications , you will be very clear . Such as the compass , the disk in the memory , and many high-tech products . So the prospects of magnetic material is very wide , the prospects of industries produced by magnetic materials is also bright .
The roles of magnesium oxide for magnetic materials are important, not only have an effect on the aging of diamagnetic material , but also play a role of anti-interference . The magnesium oxide for magnetic materials produced by Hebei Meishen Chemical Technology Group Co.,Ltd reaches the top national standard , much better than the country’s content indicators . The products of MgO≥92% , 0.15～0.25µm have the advantages of low impurity , high purity , good activity and other aspects .Of course , it is our trustworthy products .
Produce magnesium oxide for magnetic materials by using soluble salt and ammonium bicarbonate as raw materials , adopting the most advanced dolomite carbonization method . The quality of “MEISHEN” brand is very stable , and the company is a professional production enterprise designated by the state .
Now the market appeared many fake "MEISHEN" brand of magnesium oxide for magnetic materials , it makes consumers confused about identifying and choosing .The experts of Hebei Meishen Chemical Technology Group suggest that you can consult our online service , or directly dial our phone number , we can guarantee the quality of products .

The color of magnesium oxide
The color of the magnesium oxide mainly depends on the color of ore , the content of silica and caustic soda in magnesium oxide .
First of all , different places of ore has different color , and the color is difficult to be changed . The color of the magnesium oxide mainly depends on the content of silica . Silica is exist as impurities in magnesium oxide , the higher silica content , the more white of magnesium oxide(you can go and look talc , the main ingredient is silica) . However, if the silica content exceeds 8% , it will influence the strength and clotting time of magnesite products . The content of magnesium oxide so-called white is between 5.5% -8% , yellow magnesium oxide is generally between 2.5%-4% .
