轻烧镁粉http://www.ykbhlm.com 轻烧镁被广泛用于于建材、化工、冶金、医药等多个领域,是生产防火板、轻质隔墙板、硫酸镁、造纸、除硫工艺、钢厂护炉溅渣等的理想材料 。
轻烧镁粉的制取:
将菱镁矿、水镁石和由海水或卤水中提取的氢氧化镁经800~1000℃左右煅烧,使其分解排出CO2或H2O,即得到轻烧镁粉,也称轻烧氧化镁、苛性氧化镁或轻烧镁,俗称苦土粉。轻烧镁粉质地疏松、化学活性大,既可以用于制造镁水泥、菱镁建材制品、隔热保温材料等,又是二步煅烧法生产优质镁砂的中间产物。
Light-burned magnesium powder http://www.ykbhlm.com Light-burned magnesium is widely used in many fields such as building materials, chemical industry, metallurgy, medicine, etc. It is used in the production of fire-proof boards, lightweight partition boards, magnesium sulfate, papermaking, Ideal material for sulphur process, slag splashing in steel plant protection furnace, etc.
Preparation of lightly burned magnesium powder:
Calcined magnesite, brucite and magnesium hydroxide extracted from seawater or brine are calcined at about 800-1000 ° C to decompose and discharge CO2 or H2O, to obtain light-burned magnesium powder, also called light-burned magnesium oxide, caustic oxidation Magnesium or lightly burned magnesium, commonly known as bitter earth powder. Light-burned magnesium powder has a loose texture and high chemical activity. It can be used in the manufacture of magnesium cement, magnesite building materials, thermal insulation materials, etc. It is also an intermediate product of two-step calcination to produce high-quality magnesia.
