Quick lime, mainly composed of calcium oxide, is usually prepared by calcining natural rocks with calcium carbonate as the main component at high temperatures, which can be decomposed into carbon dioxide and calcium oxide (chemical formula: CaO, namely quicklime, also known as dolomite).
All natural rocks, such as limestone, chalk and dolomitic limestone, which are mainly composed of calcium carbonate, can be used to produce lime.
Powder Requirements(1) For Sewage Treatment
The discharge of wastewater from quicklime industry and municipal wastewater is increasing year by year. Quicklime wastewater treatment is widely used in papermaking, brewing, chemical industry, printing and dyeing industry, which is conducive to improving the reuse rate of industrial water and promoting the recycling of wastewater.(2) For Desulfurization in Metallurgical Iron & Steel Industry
Green water and blue sky are protected, and environmental protection policies are becoming increasingly stringent. Quicklime is used to purify sulfur dioxide produced during coal combustion in key industries such as iron and steel, power, chemical industry and coal.(3) To Make Building Materials & Aerated Bricks, etc.
Lime is also widely used as building materials, and it can be used to make calcium hydroxide and cement accelerator. It is also used to make new type of environmental friendly aerated brick, which causes light weight, heat insulation, waterproof and other functions, and plays a very important role in the development of modern construction industry.
