How to use quicklime moistureproof?
Quicklime can be moisture-proof, calcium oxide and water reaction. Put a solid calcium oxide on the line, if it is to eat, it is best to take a bag of calcium oxideThe main composition of calcium oxide, usually method was mainly composed of calcium carbonate rock, calcined at high temperature, then decomposition of carbon dioxide and calcium oxide (chemical formula: CaO, which is also known as lime, marble).
Calcium carbonate as the main component of natural rocks, such as limestone, chalk, dolomite limestone, can be used to produce lime.In the actual production, in order to speed up the decomposition, calcination temperature often increased to 1000 ~ 1100 C. Due to the large size of limestone raw material or the uneven distribution of temperature in the kiln, lime and lime are often contained in lime. The calcium carbonate in the lime is not completely decomposed, and the adhesive force is not used. Burned lime dense structure, often coated with a layer of molten surface, melting very slowly. Because the production of raw materials often contain magnesium carbonate (MgCO3), because this lime also contains minor components of Magnesium Oxide (MgO), according to the number of Magnesium Oxide content, lime into calcium lime (MgO = 5%) and magnesia lime (MgO>5%).
The original lime production process is the limestone and fuel (wood) layered laying, firing a week. Modern machinery, semi mechanized shaft kiln and rotary kiln, boiling furnace and other equipment for production. The calcining time is shortened correspondingly, and the production of lime in rotary kiln is only 2 to 4 hours, and the production efficiency can be increased by more than 5 times. In recent years, there have been cross flow, double slope type and oil burning shaft kiln and preheater with a short rotary kiln and other energy-saving effect of significant technology and equipment, fuel is also expanded to coal, coke, heavy oil or liquefied petroleum gas, etc..
