Product Description

Calcium hydroxide, commonly referred to as slaked lime, is described by the chemical formula Ca(OH)2. It is an inorganic compound which has a white, powdery appearance in its solid-state. However, Ca(OH)2 has a colourless appearance in its crystalline form. The alternate names of this compound include hydrated lime, slack lime, pickling lime, and caustic lime. Generally, calcium hydroxide is prepared by mixing water and calcium oxide (also known as quick lime). The chemical reaction between sodium hydroxide and calcium chloride dissolved in water (aqueous CaCl2) also yields this compound. The structure of a Ca(OH)2

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

Basic uses of calcium hydroxide products:

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.

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.
