Using the high technology, the company is engaged in production of highly purified spherical metal magnesium granule, which has the the granularity of 0.2mm-2mm(10-75mesh), magnesium content of over 99.5% and loose thickness of 0.1-0.75g/cm3. The product exceeds GB5149.
Using the high technology, the company is engaged in production of highly purified spherical metal magnesium granule, which has the the granularity of 0.2mm-2mm(10-75mesh), magnesium content of over 99.5% and loose thickness of
0.1-0.75g/cm3. The product exceeds GB5149.1-2004 of China and has the active magnesium of over 98.5%. and foreign matters of Zn<0.l %, Fe<0.2%, Ca<0.15%, Mn<0.l %, C1<0.03%, H20<0.05%, others metallics impurities less than 0.5%, and hydrochloric acid insolubles less than 0.2%. The company turns out magnesium granule in spherical shape instead of traditional rhombus shape, which is rarely seen in the world and used much better than those in rhombus shape.
The characteristic of magnesium granule is: it is flammable and explosive, and brings high temperature and glaring light when burning. Therefore, magnesium powder is widely used in such scientific areas as military and aviation industries, The chemical performance of magnesium is very active, which is mostly used in metallurgical industry. Magnesium granule can server as desulfurizer or cleaning agent for steel-making industry and casting of non-ferrous metals, and reducer for production of rare metal. In chemical industry, magnesium granule also can be used as dehydrant for organic compound or to directly make organic compound of magnesium. In recent years, magnesium powder has been mostly used in spaying, coating, anti-corrosion, monocrystalline silicon, polycrystalline silicon, and casting of metallurgical powder as well.
Non-oriented Silicon Steel Insulating Coating Liquid (Magnesium Chromate Coating Liquid)
Non-oriented Silicon Steel Insulating Coating Liquid is mainly applied to the non-oriented silicon steel sheet, which first used in the production of non-oriented electrical steel. At present, most of the domestics silicon steel producers adopted semi-organic masking liquid of Magnesium Chromate. The film formed by this coating material not only has the characteristics of good insulation, high heat resistance, but also possess strong adhesion, corrosion resistance, punching property and weldability.
