PRODUCTS
Main ingredients: Calcium hydroxide, chemical formula Ca(OH)2
Features:
The content ≥90.0% (superior grade) or ≥95.0% (superior grade) can be used in rubber and petrochemical additives. For example, it can be added to lubricating oil in the petroleum industry to prevent coking, sludge deposition, neutralization and corrosion protection. Need to use, but the amount is small. In the electroplating industry, bleaching and dyeing industry, it is used to improve acidic sewage and neutralize the pH value, especially in the electroplating alumina industry, calcium hydroxide must be used to treat sewage, otherwise the aluminum will exceed the standard. At the same time, it can be used for flue gas desulfurization or garbage incineration in thermal power plants, and the flue gas after desulfurization can be discharged after being dusted by a dust collector to meet environmental protection standards.
Control indicators:
The quality control of our company's industrial-grade calcium hydroxide products is implemented in accordance with the national industry standard HG/T 4120-2009
