Calcium hydrate in powder form

摘要

The technical solution concerns calcium hydroxide in powder form on the basis of waste carbide lime, where the calcium hydroxide consists of 50 to 99 % by weight of the waste carbide lime and 50 to 1 % by weight of drying admixture that present industrial wastes, either fire dust form fumous gases of calcium carbide production or a mixture of fire dust form fumous gases of calcium carbide production and calcific dust from communications at calcium carbide production and eventually calcific dust from rotary kiln of lime production.
