Product Description
Iron-free aluminum sulfate (Aluminum Sulfate) is an inorganic compound with the chemical formula Al2(SO4)3, which is widely used in multiple industrial fields. Compared with ordinary aluminum sulfate, iron-free aluminum sulfate does not contain iron or contains very low iron, and has higher purity and better performance.
Product characteristics
High purity: Iron-free aluminum sulfate does not contain iron or contains very low iron, which ensures the purity and stability of the product.
Good solubility: It can be dissolved in both cold and hot water, and the solubility increases with increasing temperature.
Safety and environmental protection: It meets national environmental protection standards and does not contain harmful substances.
Application fields
Papermaking industry: Used as a papermaking sizing agent to improve the strength and printing quality of paper.
Water treatment: As a flocculant for drinking water, industrial water and wastewater treatment, it effectively removes suspended matter and harmful substances.
Chemical raw materials: Used in the production of clarifiers, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, paper forging white, titanium dioxide post-membrane treatment, catalyst carriers, etc.
Other uses: such as mordant, tanning agent, oil decolorizing agent, wood preservative, foam fire extinguishing agent, cosmetic raw material, etc.
Low-iron aluminum sulfate is an aluminum sulfate product with a lower iron content. Compared with ordinary aluminum sulfate, its iron content is lower, but it still contains a certain amount of iron.
Product Characteristics
Low iron content: Low-iron aluminum sulfate has a low iron content and can meet the requirements of most industrial applications.
Good solubility: It has good solubility in water and can be quickly mixed with water.
Good stability: During storage and use, low-iron aluminum sulfate has good stability and is not easy to decompose.
Application areas
Papermaking industry: used as a papermaking sizing agent to improve the strength and printing quality of paper.
Water treatment: used as a flocculant for drinking water, industrial water and wastewater treatment to remove suspended matter and harmful substances.
Chemical raw materials: used to produce clarifiers, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, paper forging white, etc.
Pesticide industry: as a raw material for certain pesticides, it helps to improve the effectiveness of pesticides.
