Density of quicklime powder
If the lime powder is all composed by CaO, then the density of 3320 kg / M fand. However, quicklime powder is a mixture, there is no CaCO3 into the CaO, so its density is not a fixed value.The main component of the natural calcium carbonate rock, calcined at appropriate temperature, the removal of the decomposition of carbon dioxide, the resulting calcium oxide (CaO) as the main component of the product that is lime, also known as quicklime.
The construction of quicklime powder is based on the construction of lime as raw material, after grinding into powder. According to its chemical composition is divided into calcium quicklime powder and magnesium quicklime powder. The content of Magnesium Oxide is less than or equal to 5%, and the content of Magnesium Oxide is more than 5%. Building lime powder is divided into superior products, first-class and qualified crystal three grades. Fineness requirements: o.9mm sieve Yu: excellent products is less than 0.2%; grade of not greater than 0.5%; the qualified product is less than 1.5%; 0.125mm sieve Yu: excellent products is less than 7%; grade of not more than 12% qualified products is not greater than 18%. The lime powder for building is made of lime as raw material. According to its chemical composition is divided into calcium slaked lime powder, magnesium powder and lime powder. Magnesium Oxide content of calcium lime powder is less than 4%; the content of magnesia lime powder Magnesium Oxide equal to or greater than 4% and less than 24%; elimination of Magnesium Oxide content of lime dolomite is equal to or greater than 24% and less than 30%. Building lime powder is divided into superior products, first-class products, qualified three grades. The surface layer of superior products, first-class for plastering layer and intermediate coating; qualified for masonry. Fineness requirements: o.9mm sieve: excellent products, first-class goods are more than 0; the qualified product is less than 0.5%; 0.125mm sieve Yu: excellent products is less than 3%; grade of not more than 10% qualified products is not greater than 15%.
Quicklime powder is divided into several. The lime used in the decoration project is made of lime, lime and lime powder. Building quicklime is the main component of calcium carbonate as raw materials (such as limestone, etc.), in the sintering temperature below. According to the chemical composition, it can be divided into calcareous quicklime and magnesia quicklime. The content of Magnesium Oxide is less than or equal to 5%, and the content of Magnesium Oxide 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.
