Lime powder is divided into several kinds. The lime used in decoration works includes building lime, Building lime powder and Building lime powder. Building lime is a raw material (such as limestone) made of calcium carbonate, which is calcined at a temperature lower than the sintering temperature. According to its chemical components are divided into calcareous quicklime and magnesian lime. The content of Magnesium Oxide in calcareous lime is less than or equal to 5%; the content of Magnesium Oxide in magnesian lime is more than 5%. Building lime is divided into superior products, first-class quality and grade three. Superior product the pulp capacity of not less than 2.8L / kg grade; the pulp capacity of not less than 2.3L / kg; qualified slurry is not less than 2.0L / kg.
The natural rock, which is mainly composed of calcium carbonate, is calcined at an appropriate temperature to remove carbon dioxide from decomposition. The product obtained with calcium oxide (CaO) as the main component is lime, also known as quicklime.
If the lime powder is all composed by CaO, then the density of 3320 kg / M fand. But the lime powder is a mixture, and there is no CaCO3 that turns into CaO, so its density is not a definite value.
