Description
1. It can be used as a raw material for the production of calcium carbonate.
2. Calcium hydroxide is alkaline, so it can be used to reduce the acidity of the soil, thereby improving the soil structure. The Bordeaux mixture in pesticides is prepared according to a certain ratio by using milk of lime (calcium hydroxide dissolved in water) and copper sulfate aqueous solution. In winter, the trees are overwintered to prevent insects, and 80 cm of lime slurry is applied above the roots of the trees.
3. High-quality products are mainly used in the production of epichlorohydrin and propylene oxide.
4. It can be used in rubber and petrochemical additives, such as in lubricating oil in the petroleum industry, to prevent coking, sludge deposition, neutralization and anticorrosion.
5. Used to prepare bleaching powder, bleaching powder essence, disinfectant, antacid, astringent, hard water softener, soil acid preventer, 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. In the production of sugar industry, calcium hydroxide is first used to neutralize the acid in the syrup, and then carbon dioxide is introduced to react with the remaining calcium hydroxide to form a precipitate that is filtered out, thereby reducing the sour taste of sugar.
