Calcium oxide Packaging: plastic bags or story brown paper bags full open or in opening drums; threaded glass, metal cover pressure bottles, plastic bottles or metal (cans) outside the ordinary wooden box; thread mouth bottle , plastic bottles or tinplate barrels (LP), full floor grille boxes, fibreboard or plywood box. Lime Preparation: In the actual production of industrial-grade calcium oxide quoted, in order to accelerate the decomposition, the calcination temperature is often increased to 1000 ~ 1100 ℃. Due to the large size of limestone calcination kiln feed or uneven distribution of temperature and other factors of high quality industrial grade calcium oxide, lime often contain less fire burned lime and lime. Due to fire lime calcium carbonate is not completely decomposed industrial calcium oxide prices, lack of adhesion when used. Burned lime dense structure, often coated with a layer of surface melt industrial grade calcium oxide dissolves very slowly. As the production of raw materials often contain magnesium carbonate (MgCO3), therefore lime also contains a minor component of magnesium oxide (MgO), depending on how much magnesium content, calcium quicklime into lime (MgO≤5%) lime and magnesia (MgO > 5%).
