輕燒鎂粉(Mgo)，中文又稱輕燒粉，輕燒氧化鎂，氧化鎂粉，菱苦土，苦土粉；英文別名Magnesium oxide ，Magnesia usta ，Calcined magnesia ，Magcal ，Maglit.輕燒鎂粉，白色細微粉末，無臭、無味，該品不溶于水或乙醇，微溶于乙二醇，熔點2852℃，沸點3600℃，輕燒鎂粉有高度耐火絕緣性能。經1000℃以上高溫灼燒可轉變為晶體，升至1500℃以上則成死燒氧化鎂(也就是所說的鎂砂)或燒結氧化鎂。輕燒鎂粉是堿性氧化物,具有堿性氧化物的通性，屬于膠凝材料?！”┞对诳諝庵?，容易吸收水分和二氧化碳而逐漸成為堿式碳酸鎂，與水結合生成氫氧化鎂，呈微堿性反應，飽和水溶液的pH為10.3。溶于酸和銨鹽難溶于水，其溶液呈堿性。不溶于乙醇。
Light burned magnesium powder is a flex-resistant, pressure-resistant, high-strength, gel material that is widely used in rubber, plastics, wires, cable dyes, paints, glass, ceramics, chemical reagents, medicine, food additives, etc .; Progress and development, the industrial use of magnesium oxide has become more extensive.
Lightly Burned Magnesium Powder (Mgo), also known as Chinese Lightly Burned Powder, Lightly Burned Magnesium Oxide, Magnesium Oxide Powder, Lingkuo Earth, Bitter Earth Powder; English alias Magnesium oxide, Magnesia usta, Calcined magnesia, Magcal, Maglit. Powder, white fine powder, odorless, tasteless, this product is insoluble in water or ethanol, slightly soluble in ethylene glycol, melting point 2852 ℃, boiling point 3600 ℃, light burned magnesium powder has high fire-resistant insulation properties. It can be transformed into crystals when it is burned at a temperature higher than 1000 ° C, and it will become dead burned magnesia (also known as magnesia) or sintered magnesia when it rises above 1500 ° C. Light-burned magnesium powder is an alkaline oxide, which has the permeability of alkaline oxide, and belongs to a gelling material. When exposed to air, it easily absorbs water and carbon dioxide and gradually becomes basic magnesium carbonate. It combines with water to form magnesium hydroxide, which shows a slightly alkaline reaction. The pH of the saturated aqueous solution is 10.3. It is soluble in acid and ammonium salt, hardly soluble in water, and its solution is alkaline. Insoluble in ethanol.
Physical and chemical index of light burned magnesium powder
As one of the leading enterprises in the magnesium industry, Yingkou Bohai Ling Magnesium Material Co., Ltd. produces light-burned magnesium powder with good color, high purity, magnesium content of more than 85%, and processing meshes ranging from 120 mesh to 325 mesh. . The light-burned magnesium powder produced far exceeds the domestic industry standards. On the basis of smooth, clean, beautiful and elegant, it has the advantages of pressure resistance, wear resistance, high temperature resistance, corrosion resistance, fire resistance and flame retardant. It is the key promotion in China today. The ideal raw material for the replacement of green products in thermal insulation buildings. Bohai products sell well both at home and abroad, and their product quality and corporate reputation are widely praised and highly praised.
