Research on flame retardant nano magnesium hydroxide process

China’s plastic flame retardant material is mainly based on decabromodiphenyl ether, but decabromodiphenyl ether in combustion will produce toxic carcinogenic polybrominated dibenzofuran and other substances, and make it some countries to resist the use of. Therefore, flame-retardant materials also develop towards the direction of high efficiency, low toxicity and low smoke. It is necessary to develop nontoxic flame retardant with excellent performance. Inorganic materials used as flame retardants include Mg(OH)2, AL(OH)3, Sb2O3, etc. These inorganic flame retardants not only [...]

The difference between industrial grade lithium carbonate and battery grade lithium carbonate

Compared with industrial grade, battery grade lithium carbonate has high purity, few impurities and good performance. Lithium carbonate is an inorganic compound. It is colorless monoclinic crystal or white powder. Its chemical formula is Li2CO3. Soluble in dilute acid, slightly soluble in water, greater solubility in cold water than in hot water. Insoluble in alcohol and acetone. Density 2.11g/cm3, melting point 723℃. Can be used to make ceramic, medicine, catalyst, commonly used lithium ion battery materials. Compounds, lithium metals and isotopes [...]

Properties of nano-aluminum nitride filled ptfe composites

Nano aluminum nitride powder has high specific surface area, high hardness, high thermal conductivity, high insulation and other characteristics, belongs to diamond-like nitride, can be stable to 2200℃, high strength at room temperature, good compatibility with the matrix interface, can improve the thermal conductivity and dielectric properties, mechanical properties and wear resistance of the composite. PTFE, commonly known as “plastic king”, has a linear molecular chain structure and is a non-polar polymer, with good chemical corrosion resistance, high and low [...]
