Special Scale Inhibitor for Heating Networks

Heat Network Special Scale Inhibitor

I. Performance and Uses

This product is compounded from organic phosphonic acid, polycarboxylic acid, alkaline synergists, and other components, offering excellent corrosion inhibition and scale inhibition properties. It features outstanding high-temperature resistance and is alkaline in nature, with a pH value comparable to that of boiler water. It can be effectively applied for internal water treatment in low-pressure boilers, including hot water heating, steam, and locomotive boilers. It is also suitable for corrosion and scale inhibition in systems such as seawater desalination, distillation, and automobile radiators.

III. Usage Method
Add the agent to the system's make-up water at a ratio of 200g per ton of water. During use, ensure regular blowdown: once per hour for 5–10 seconds each time. If the system is operating with existing scale, increase the dosage and frequency of blowdown. After 10–20 days of operation, manually remove any dislodged scale to prevent clogging of pipelines, then resume normal operation. If possible, monitor the system's water concentration ratio, keeping it around 10 times. Adjust other parameters in accordance with relevant labor department regulations (e.g., boiler water pH 10–12). The chemical dosing tank should be made of plastic; if using a cement tank, apply anti-corrosion treatment to prevent erosion by the agent, which could increase water hardness.
The total hardness of boiler make-up water should be controlled within 200mg/L. If hardness is too high, use lime treatment or other methods to reduce it; otherwise, the scale inhibition effect may be compromised.

IV. Packaging and Storage
This product is packaged in plastic drums or kraft paper bags, 25kg per drum/bag, or as per customer requirements. Store in a cool place with a shelf life of twelve months.

V. Safety and Protection
This specialized corrosion and scale inhibitor is alkaline. Use appropriate labor protection during operation and avoid contact with skin and eyes. In case of contact, rinse thoroughly with plenty of water.
