About calcium hydoxide,we can supply
≥90% grade calcium Hydroxide
≥95% grade calcium hydroxide
98%-99.5% grade calcium hydrooxide (We are the first factory in Chinese Mainland that can produce this product)
COA,MSDS,TDS,SGS files for each grade are available.
1. Calcium hydroxide is used as an environmentally friendly neutralizer for acid wastewater, sewage treatment, boiler flue gas desulfurization.
2. Calcium hydroxide can also be used as chemical raw materials, additives, additives, fillers for leather, metallurgy, coatings, petroleum lubricants, paper and so on.
3. Other uses of calcium hydroxide:
Calcium hydroxide is used as stone cutting aid, soil stabilizer, concrete tempering agent, chemical reagent, gypsum board caulking coagulant, construction adhesive ingredients, hard water softener, plastic fiber and so on.
A, calcium hydroxide environmental treatment with Ca(OH)2 screening rate of 125 mesh ≥90%
B, calcium hydroxide as a strong alkaline flocculant to neutralize acidic wastewater to make acidic wastewater neutral.
C, calcium hydroxide absorbs SO 2 in boiler flue gas, so that the sulfur content of emission flue gas meets environmental protection standards.
D, calcium hydroxide through.
E, calcium hydroxide wastewater treatment effect comparison, is the conventional alkaline coagulant wastewater treatment is recognized as the world's most alkaline neutralizer.
calcium hydroxide product use method:
1. When calcium hydroxide is added by dry method, the equipment is simple, but the reaction is slow and the utilization rate is not high;
When wet calcium hydroxide is added, it is generally prepared into a calcium hydroxide lime emulsion with a mass fraction of 5%-10%, which has a fast reaction and is stirred for 5-20min.
2. Handling of abnormal problems: When the influent PH value changes greatly, the dosage should be increased or decreased in time;
Calcium hydroxide emulsion should be diluted after adding, easy to mix reaction;
The sludge produced in the process of neutralization should be separated and removed in time.
