High purity quicklime is widely used in industrial production due to its high content and low impurities. It can be used as an additive or filler for plastics and rubber.
Quicklime is a fundamental raw material in many chemical industries, with its core functions reflected in high reactivity, strong alkalinity, and wide chemical compatibility.
Quicklime (CaO) plays a key role in the field of environmental protection due to its strong alkalinity, adsorption, and chemical reactivity. It is widely used in industrial wastewater treatment, flue gas desulfurization, and acid soil improvement.
