This product can prevent carbonate polymer small grain growth, and to distort the lattice distortion, so that the circulating cooling water in the heat exchanger surface carbonate does not form a hard scale. At the same time, its components and other ingredients with the organic phosphate metal protective film is formed, so that he may be combined with the circulating cooling water such as calcium ion, to prevent metal corrosion. This product is suitable for a wide range of PH value, the PH value of scale and corrosion inhibition have between 7.0-9.5, not out of control due to the PH value, resulting in corrosion, scaling and other issues. Quality Index: Project A Class B Class C azole% ≥ - 1.0 3.0% ≥ 6.8 12.5 Asia phosphate salts% ≤ 2.25 3.0 orthophosphate% ≤ 0.75 Solid content% ≥ 32 23 Density (20 ℃) ??g / cm3 1.15 1.12 PH value (1% solution) 3.0 ± 1.5 3.0 ± 1.5 Usage: This product is most suitable for power plant cooling water for copper and aluminum and steel have good corrosion inhibition, according to the concentration ratio and the thermal load size, and turbidity and other parameters to determine the dosage of this product. Usage and dosage: when used in water treatment plant, the general dosage of 3-10mg / L; for other circulating cooling water, generally cast in between 10-40mg / L dosage. (Simulation test to determine the exact amount). Packaging and storage: This product is packed in 25kg or 200kg plastic drum. Store in a cool place (rinse with water after contact with skin).
