Audited Supplier Calcium hydroxide product packaging and storage:
1. calcium hydroxide transport precautions: the packaging should be complete when shipping, loading should be secure. Calcium hydroxide should not be transported in rainy days.
2. calcium hydroxide storage precautions: store in a cool, ventilated warehouse. The humidity in the warehouse * is not more than 85%. The packaging must be completely sealed to prevent calcium hydroxide moisture absorption.
3. calcium hydroxide outer packaging are 1200 kg/ton bag and 25 kg/bag woven bag.
4. according to the different actual needs of customers, calcium hydroxide can also be transported by tank truck.
Calcium hydroxide is also known as hydrated lime, slaked lime, the use of high-quality limestone through strict calcination processing, made of excellent ash blocks as raw materials, and then carefully selected to remove impurities, through program-controlled computer analysis, grinding and other processes. Main uses: Widely used in metallurgical co-solvent, chemical industry, paper making, water treatment, sewage purification treatment, leather, construction, rubber, plastic filling additives, thermal power plant desulfurization, acid removal and other industries.
Calcium hydroxide: The molecular weight of Ca(OH)2 is 74, the melting point is 5220 degrees Celsius, the Ph value is greater than or equal to 12, is strongly alkaline, white and fine powder, soluble in water, soluble in acid, glycerin, ammonium chloride, soluble in acid to release a lot of heat, the relative density is 2.24, its clarified aqueous solution is colorless and odorless alkaline transparent liquid, placed in the air gradually absorbed. Oxidize carbon to calcium carbonate.
Calcium hydroxide is mainly used in environmental protection sewage treatment, sludge conditioning, flue gas desulfurization, leather leach, building materials, paint, nonferrous metal smelting, feed addition, calcium base grease, dyes, refrigerants and so on.

calcium hydroxide product introduction:
1. Nicknames of calcium hydroxide: slaked lime, hydrated lime
2. The main component of calcium hydroxide :Ca(OH)2, molecular weight 74.8
3. Production method of calcium hydroxide: The finished product is obtained by digesting calcium oxide with water and drying, sifting and windpicking.
4. Physical and chemical properties of calcium hydroxide: strongly alkaline. Placed in the air, it gradually absorbs carbon dioxide and becomes calcium carbonate. Slightly soluble in water, soluble in acid. With a density of 22.4g/cm3, its clarified aqueous solution is a colorless odorless alkaline transparent liquid with a PH value of 12.4
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.
Used for agricultural acid soil improvement, pond disinfection:Lime is used in construction:
