輕燒鎂粉一般做什么用 What is the general use of light burning magnesium powder

    辨別輕燒鎂粉好壞,首先從顏色,輕燒的一般稱黃白色,溫度高.雜質大顏色偏重于黃深色。其次,根據化學成分,灼減一般在4-5% ,氧化鎂90%以上,氧化鈣在1.5%一下,其他鐵,硅好的分別都在1.0一下。另外若有條件的話,并且很在意輕燒鎂粉的活性,那就需要再檢測活性。鎂含量越高,雜質越少越好,活性越高越好。輕燒鎂粉主要是菱鎂礦低溫煅燒(600-800度),質地疏松,化學活性高,也稱苛性氧化鎂或苦土粉,顏色淡黃。因其活性大,和其他原料配比燒結很容易反應。沒有聽說可以直接用于煙火!主要用于煅燒尖晶石,堿性等耐火材料。

Distinguish the quality of lightly burned magnesium powder, first of all from the color, lightly burned is generally called yellow-white, high temperature. The color of large impurities is more important than the dark yellow. Secondly, according to the chemical composition, the burning reduction is generally 4-5%, the magnesium oxide is more than 90%, the calcium oxide is less than 1.5%, and the other iron and silicon are better than 1.0. In addition, if there are conditions, and you are very concerned about the activity of lightly burned magnesium powder, you need to test the activity again. The higher the magnesium content, the less the impurities, the better, and the higher the activity, the better. Light-burned magnesium powder is mainly low-temperature calcined magnesite (600-800 degrees), with loose texture and high chemical activity. Because of its high activity, it is easy to react when sintered with other raw materials. I haven't heard that it can be used directly for fireworks! Mainly used for calcining spinel, alkali and other refractories.輕燒鎂粉
