Application field

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 the soil, thereby improving the soil structure. 3. High-quality products are mainly used to produce epichlorohydrin and propylene oxide.

4. It can be used in rubber and petrochemical additives. For example, it can be added to lubricating oil in the petroleum industry to prevent coking, sludge deposition, neutralization and corrosion protection.

5. Used to prepare bleaching powder, bleaching powder concentrate, disinfectant, antacid, astringent, hard water softener, soil acid preventive agent, depilatory agent, buffer, neutralizer, curing agent, etc.

6. Calcium hydroxide and carbon dioxide in the air will also react to form calcium carbonate which is insoluble in water.
