Product Introduction
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation. Limewater is the common name for a saturated solution of calcium hydroxide.
Product Performance
1) Ca(OH)2: ≥90-96%
2) Magnesium & Alkali: ≤2-3 %
3) Insoluble hydrochloride: ≤0.1-1 %
4) Fe:≤0.05-0.1%
5)Moisture:≤0.5-2.0%
6)Heavy metals (calculated in Pb):≤0.002%
Product Application
1)Sewage treatment: Some sewage produced in production of chemical plant is acidic; it can be put slaked lime to neutralize acidic material. Because, slaked lime is also relatively cheaper in economic interests. So many chemical plants use it to deal with acidic sewage.
2) Environmental protection flue gas desulfurization:It is mainly used to neutralize sulfur dioxide, sulfur trioxide, small part of fluoride ions, chloride ion sand other acidic gas, it greatly reduces adverse effect from production enterprises on environment, makes sulfur content flue in gas emission meeting environmental standards.
3) Metallurgical industry:In order to coating metal surface, firstly remove impurities from metal plate surface (including metal oxide), so firstly use dilute sulfuric acid removing it. The sewage generated in the production needs to be neutralized with calcium hydroxide.
4) civil buildings:In refractory material: it can be use as additive to enhance strength and viscosity of brick.
In the paint: calcium hydroxide in the air reacts with carbon dioxide and generates calcium carbonate that is white, hard and aid-coagulation;
