Main ingredient: Calcium oxide, chemical formula CaO

 

Features:

Calcium oxide is an inorganic compound, commonly known as quicklime. It is white or gray in the form of lumps and powders. It is soluble in acids, glycerin and sucrose solutions, and almost insoluble in ethanol. Calcium oxide is an alkaline oxide and is sensitive to moisture. It easily absorbs carbon dioxide and moisture from the air, reacts with water to form calcium hydroxide (Ca(OH) 2 ) and generates a large amount of heat, which is corrosive.

Our company produces highly active calcium oxide with high calcium content, stable composition and low impurity content (especially S and P content). The lime has large pores, small specific gravity, high activity and fast reaction speed. In the smelting and chemical industries, the reaction time is limited. If the calcium content of lime is high but the activity is not high (uneven heating during the lime calcination process causes calcium oxide crystals to grow too fast and the pores between crystals are small), the reaction will not occur within the limited time. After the reaction is completed, the unfinished lime will be discharged as waste residue, resulting in an increase in the amount of lime used and an increase in the customer's production costs. Active lime can completely solve this problem. Highly active calcium oxide can be used in metallurgy, papermaking, environmental protection, aquaculture and other industries. The specific Index can be customized according to customer requirements.
