Lime deep processing: soda ash (Na2CO3) calcium chloride method. Calcium chloride is added steel in an aqueous solution with lime soda prices, it can produce calcium carbonate precipitation. Alkaline: steelmaking lime supplier in the production of caustic soda (NaOH) process, a byproduct obtained PCC. Soda lime is added in aqueous solution to produce calcium carbonate precipitate, and also get high-quality steel with an aqueous solution of caustic soda lime, calcium carbonate precipitation finally dehydrated, dried and pulverized to thus prepare PCC. Lime: theoretical concepts of active lime, is a chemical properties and lively, strong ability to participate in the reaction, containing S (sulfur), low P (phosphorus) and other harmful impurities. It has the following main characteristics: volume density, porosity, large surface area, the reaction performance. It also has: CaO crystal fine: ≤1 wm, CaO content: ≥90%, lower S, P content: <0.02% and traces, SiO2 + Fe2O3 + Al2O3 content is low: <2% residual CO2 Low: ≤2%, etc. Characteristics of burnt lime light.
