Product Application

Calcium hydroxide, also known as hydrated lime, is widely used across various industries due to its strong alkalinity, reactivity, and purity. It plays a key role in environmental treatment, such as wastewater neutralization and heavy metal removal. In flue gas desulfurization, it serves as an effective sorbent for SO2 control in power plants and industrial boilers. The construction industry uses it in the formulation of mortar, lime plaster, and as a cement additive. In the chemical sector, it is used for producing calcium salts, petroleum additives, and rubber processing agents. Food-grade calcium hydroxide (E526) is also applied in the food industry as a pH regulator for products like candies and beverages. Additionally, ultra-high purity grades are used in electronic applications, including high-end chemical synthesis and slurry formulations.
