| 1. Main Ingredient: calcium hydroxide Chemical formula: Ca (OH) 2 |
| 2. Physical and chemical properties: Calcium hydroxide is also called slaked lime and slaked lime. Fine white powder, specific gravity 2.24, heated to 580 ºC loses bound water to become calcium oxide, calcium hydroxide dew placed in the air can slowly absorb carbon dioxide into calcium carbonate. Soluble in acid, insoluble in water, insoluble in alcohol. Our company uses high-quality limestone through strict calcination processing to make excellent quick lime blocks as raw materials. After careful selection and removal of impurities, it adopts advanced dry three-digestion process, program-controlled microcomputer analysis, air separation and other processes. The main production of 325 mesh calcium hydroxide, other mesh calcium hydroxide can be adjusted according to customer requirements. |
| 3. Application: |
| (1) Calcium hydroxide is used as chemical raw materials, additives, additives, fillers for tanning, metallurgy, coatings, petroleum lubricants, papermaking, feed additives, etc. |
| (2) Calcium hydroxide is used as environmental protection neutralizer for acid wastewater, sewage treatment, and boiler flue gas desulfurization. Calcium hydroxide is used for environmental protection. Ca (OH) 2 sieving rate 325 mesh ≥95% is used as a strong alkaline agent to neutralize acid wastewater or heavy metal wastewater, making acid wastewater neutral. Compared with calcium hydroxide wastewater treatment, compared with the 30% sodium hydroxide alkaline solution, the price per ton of sodium hydroxide alkaline solution is equivalent to that of each ton of calcium hydroxide powder, but from the perspective of treatment, calcium hydroxide powder The price is less than 50% of the sodium hydroxide alkaline solution. From the point of view of coagulation and decolorization, it is better than sodium hydroxide alkaline solution, and it is a recognized alkaline neutralizing agent in the world. Calcium hydroxide absorbs SO 2 in the flue gas of the boiler, so that the sulfur content of the flue gas meets the environmental protection standards. At present, the stricter the internal environmental protection is, the larger the market of calcium hydroxide will be. |
