ZHQ-LPFA-01 and ZHQ-LPFA-02 are both liquid pre-filming agents compounded with organic phosphonates, corrosion inhibitors, dispersants and other additives. When mixed at a 1:1 ratio, they can form a passivation film on steel surfaces to provide excellent protection for steel. At low dosage, they can also act as corrosion inhibitors to control initial corrosion of circulating cooling water and repair & maintain the protective film. They have a wide applicable pH range of 5.0 ~ 7.0, and tolerate calcium ion content above 40 ppm in water. They are widely applied in iron & steel, petroleum, chemical, power generation and other industries.
