Industrial Aluminum Sulfate treatment temperature of 80 ℃, the pressure is normal pressure. Before the surface treatment, Industrial Aluminum Sulfate and sodium silicate were diluted in the chemical automatic dispensing system to a working solution with a concentration of 10%. The surface treatment agent and the liquid base are added in batches to flexibly adjust the pH. The surface treatment agent after the hydrolysis rate is generally 50%.
1, the surface treatment agent used: iron-free Industrial Aluminum Sulfate (alumina ≥ 17, the amount of 110KG / T products), 45% of the liquid base according to the actual operating experience is expected to 33.33KG / T products.
2, the surface treatment agent used: sodium silicate (sodium oxide and silica ≥ 40% dosage 50KG / T), do not use liquid caustic soda.
3, the surface treatment agent used: iron-free Industrial Aluminum Sulfate (alumina ≥ 17, the amount of 110KG / T products), sodium silicate (sodium oxide and silica ≥ 40% dosage 50KG / T), 45% According to the actual operating experience is expected to 36.5KG / T products.
Iron-free Industrial Aluminum Sulfate in the manufacture of titanium dioxide in the PH value, increase the surface adhesion rate. Iron-free Industrial Aluminum Sulfate has two forms of liquid and solid. Industrial Aluminum Sulfate manufacturers on the sewage treatment of a series of research, the issue of a very interesting phenomenon, Industrial Aluminum Sulfate can be used in sewage treatment, titanium dioxide production of sub-ferrous sulfate can also be used for sewage treatment.
