What's The Magnesium Oxide Function For ABS Heat Conducting Plasticsby Hu Yanchao Magnesium oxide manufacturers in China
ABS thermal conductive plastics were prepared by blending and moulding with magnesium oxide and acrylonitrile butadiene styrene copolymer (ABS) as raw materials. It is found that the filling quantity of magnesium oxide is greatly affected by the particle size. The filling quantity of magnesium oxide with large particle size can be up to 600 parts, while the maximum quantity of magnesium oxide with small particle size can be up to 400 parts. Using percolation theory analysis of the relationship between thermal conductivity and filler volume fraction, and found that the particle size of magnesium oxide filled ABS thermal conductive plastic well within the range 300-600 in line with the critical volume fraction (phi c) 0.198 the face-centered cubic sites the percolation theory of percolation. SEM observation of the large particle size of magnesium oxide fill in ABS plastic of thermal conductivity of thermal conductivity of magnesium oxide particles connected path; ABS thermally conductive plastic filled with small particle size magnesium oxide is affected by interfacial thermal resistance in the research area, which does not conform to the percolation theory, the small particle size magnesium oxide was used to fill the gap in the large particle size magnesium oxide heat conduction network.
MeiShen is the world's leading producer of magnesium oxide,Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
