Product description
Nicknames of calcium hydroxide: slaked lime, hydrated lime.Production method of calcium hydroxide: The finished product is obtained by digesting calcium oxide with water and drying, sifting and windpicking.Physical and chemical properties of calcium hydroxide: strongly alkaline. Placed in the air, it gradually absorbs carbon dioxide and becomes calcium carbonate. Slightly soluble in water, soluble in acid. With a density of 22.4g/cm3, its clarified aqueous solution is a colorless odorless alkaline transparent liquid with a PH value of 12.4.

What are the use?
1. can be used as raw materials for the production of calcium carbonate.
2. calcium hydroxide is alkaline, so it can be used to reduce the acidity of the soil, so as to improve the structure of the soil. Bordeaux liquid in pesticides is prepared by using lime milk (calcium hydroxide dissolved in water) and copper sulfate aqueous solution in a certain proportion.
3. quality products are mainly used in the production of epichlorohydrin, propylene oxide.
4. can be used in rubber, petrochemical additives, such as the petroleum industry added in lubricating oil, can prevent coking, sludge deposition, neutralization and anti-corrosion.
5. used to produce bleaching powder, bleaching powder, disinfectant, acid, astringent, hard water softener, soil acid prevention agent, hair removal agent, buffer, neutralizer, curing agent, etc.
6. calcium hydroxide and carbon dioxide in the air will also react to form calcium carbonate that is insoluble in water. In the sugar industry, calcium hydroxide is first 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 that is filtered out to reduce the sour taste of sugar.
Storage and transportation:
1.Precautions for transportation
The packing should be in good condition and properly loaded. During the transportation process, it is necessary to ensure that the container does not leak, collapse, fall, and damage. It is strictly prohibited to mix with inflammable or combustible materials, acids, edible chemicals, etc. Should not be transported in rainy weather.
2. Precautions for storage
Store in cool, ventilated warehouse. The humidity in the warehouse is best not more than 85%. The package must be sealed properly to avoid moisture absorption. It should be separated from easy (flammable) substances, acids, etc., and should not be mixed. Storage areas should be equipped with appropriate materials to contain spills.
