LX-202 series corrosion inhibitors, zinc-based water treatment agent is a phosphorus compound containing copolymers and excellent, and anti-corrosion structure and function, without polyphosphates. Suitable longer residence time and water temperature, and can run at a higher PH value, with the copolymer compound used better. In addition, it can inhibit corrosion, film speed, good effect and other characteristics make the film. Uses: mainly used open recirculating cooling water systems, suitable for high alkalinity low hardness water quality. Usage: general dosage 10-30mg / L. (Simulation test to determine the exact amount required). Packaging and storage: 25kg plastic drum, cut open storage (water treatment after contact with the skin). Quality Index: Item Index Appearance colorless or slightly yellow transparent liquid zinc total of TP% ≥12% ≥4.5 PH value (1% solution) 2.0 ± 1.0 Density (20 ℃) ??g / cm3 ≥1.115 Solid content% ≥25
