Solubility Insoluble in ethanol, soluble in acid and glycerin. .
It is used as building materials and metallurgical flux. It is the main raw material for manufacturing calcium hydroxide and various calcium compounds. It is also a cheap alkali in the chemical industry. It is widely used in pesticides, papermaking, food, petrochemical industry, tanning and wastewater purification. Used as cement accelerator in construction.
Used as analytical reagents, spectral analysis reagents, fluxes for fluorescent powders, vegetable oil decolorizers, and carbon dioxide absorbers during gas analysis. High-purity reagents are used in epitaxy and diffusion processes in semiconductor production.
As a filler for epoxy adhesives, it can be used to prepare agricultural machinery, glue and underwater epoxy adhesives. Also used as a reagent for pre-reaction with resin. Lime has strong moisture absorption and is a cheap desiccant and alcohol dehydrating agent. It is widely used as building materials, metallurgical flux, acid wastewater treatment and sludge conditioning. It is a cheap alkali in the chemical industry and is widely used in agriculture, papermaking, petrochemicals, metal processing, tanning, food, pharmaceutical and other industries. It can also be used as a boiler decommissioning protective agent. It utilizes the hygroscopic ability of lime to keep the metal surface of the boiler water and vapor system dry and prevent corrosion. It is suitable for long-term decommissioning protection of low-pressure, medium-pressure and small-capacity drum boilers.
Used in construction, and used in the manufacture of calcium carbide, liquid soda, bleaching powder and gypsum. The laboratory is used for drying ammonia and dehydrating alcohol.
