—— Low phosphorus environment-friendly scale and corrosion inhibitor SM-303 ——
1. Performance and uses: SM-303 scale and corrosion inhibitor is an all-organic low-phosphorus corrosion and scale inhibitor developed by our company. It is low-phosphorus and environmentally friendly. It is more in line with the current environmental protection and emission requirements. It is a better replacement for high-phosphorus formulations. The corrosion and scale inhibitor. SM-303 has excellent performance in inhibiting calcium carbonate, calcium phosphate, calcium sulfate, and also has good dispersion stability to iron oxide in circulating water. This product is suitable for carbon steel, copper and copper alloys, stainless steel and other metal materials. Has excellent corrosion inhibition effect. The total alkalinity tolerance of Ca2++ can reach 1500mg/L (calculated as CaCO3), which is especially suitable for high pH, high temperature, high Ca2+, high alkalinity, high Cl-critical water quality, and can meet the requirements of high concentration multiple operation.

3. Application range SM-303 scale and corrosion inhibitor Ca2++ alkalinity tolerance has reached 1500mg/L (calculated as CaCO3), which is especially suitable for circulating cooling with high pH, high temperature, high Ca2+, high alkalinity and high concentration rate In the water system, higher chloride ions and ferric ions have little effect on this agent, no pH adjustment, simple operation, convenient management, and a very wide range of applications.
This product is a new type of water treatment corrosion and scale inhibitor that meets environmental protection requirements, and is widely used in circulating cooling water systems in industries such as steel, electric power, petrochemicals, and fertilizers. Dosing concentration . 1 0-20 mg / L (to supplement the water meter).
4. Packaging and storage SM-303 is packed in 25Kg plastic barrels. Store in a cool and ventilated place inside, the storage period is 12 months.
