Polymeric liquid aluminum sulfate, sulfuric acid concentration of about 3% will be added to the ferrous sulfate, and then adding sodium nitrite and ferrous ratio of phosphoric acid of about 3: 100, through the air or oxygen oxidation, hydrolysis, polymerization reaction of PFS. PFS method of manufacturing a solid product: 1, the use of liquid iron as raw material, Renhuai PFS, winning air as the oxidant, PFS manufacturer, after low-temperature dehydration, crushing, high temperature oxidation, Xinxinran cooling, telogenic curing, aging, crushing to finished complete. The main technical indicators Project Henan Spirit PFS indicators GB1459-93 (II) the product of total iron content% ≥18.5≥19.1 reducing substances (as Fe2 + count) 0.150.01 content%, ≤ basicity, coal washery polymeric acid iron,% 9.0-14.014.0PH (1% aqueous solution) 2.0-3.02.4 arsenic (As) content,% ≤0.00080.0001 lead (Pb) content, production PFS,% ≤0.00150.0001 insoluble content,% ≤0.50.4 Henan Golden Age produced PFS products are exported to foreign countries, invited plant procurement. Paper mill PFS, PFS Renhuai, Saatchi Saatchi water provided by the Henan water purification Material Co., Road Zhiyuan, temper forward. Spirit Henan water purification Material Co., Ltd. (www.gyssjs.com) aims to become and you win symbiosis, strategic partners to move forward, more determined to become the most influential water treatment chemicals business, and you leap to jointly Success!
