Calcium hydroxide
Calcium hydroxide is white powder. Chemical formula Ca (OH) 2, commonly known as slaked lime, slaked lime, water solution known as
clarifying water. Is a white powder solid, slightly soluble in water. Alkali calcium hydroxide has continuity, is a strong basein. Calcium hydroxide is two yuan alkali, but slightly soluble in water. Calcium hydroxide is widely used in industry.

Application
calcium hydroxide
1. It can be used as raw material for producing calcium carbonate.
2. Calcium hydroxide is alkaline, so it can be used to reduce the acidity of soil, thus playing a role in improving soil structure.The bordeaux mixture in pesticides is made from lime milk (soluble calcium hydroxide) and copper sulfate solution in a certain proportion.[7] In winter, trees are insect-resistant, with 80 cm of lime slurry coated above their roots.
3. High-quality products are mainly used for the production of epichlorohydrin and epichlorohydrin.
4, can be used in rubber, petrochemical additives, such as petroleum industry added in lubricating oil, can prevent coking, sludge deposition, neutralization and corrosion.
5. Used for making bleaching powder, bleaching powder essence, disinfectant, acid preparation agent, astringent, hard water softener, soil acid prevention agent, hair remover, buffer, neutralizing agent, curing agent, etc.[8]
6. Calcium hydroxide also reacts with carbon dioxide in the air to form calcium carbonate, which is insoluble in water.In the sugar industry, calcium hydroxide is used to neutralize the acid in the syrup, and then carbon dioxide is added to react with the remaining calcium hydroxide to form a precipitate which is filtered out to reduce the sour taste of the sugar.
