          Properties:

          DF-211 high efficiency scale inhibitor is composed of organic phosphoric acid, carboxylic acid copolymer, high effective dispersing agent and azole. It has wide application range, low toxicity, convenience and application.

          The circulating cooling water system with various materials has good anticorrosion performance, and has certain clearance and dispersion effect on the scale formed by calcium carbonate in water. This product has high temperature resistance.

          The effect of scale is obvious, and it is not easy to hydrolyze.

          Usage:

          DF-211 high efficiency scale corrosion inhibitor is mainly used in the scale inhibition of the circulating cooling water system such as power plant, iron and steel, petrochemical, chemical fertilizer, central air conditioning and other circulating cooling water systems, and the resistance to DF-211 is blocked.

          The scale inhibitor is added into the plastic charging barrel, and the dosing pump is added to the circulating water system by continuous adding way. The daily dosage is generally 10-30mg/L and residual chlorine control.

          The scope of the system is at 0.5-0.8mg/L.

          Package and Storage:

          DF-211 high efficiency scale corrosion inhibitor is packed in plastic bucket and 25kg/ barrel, and stored in a cool and dry place with a storage period of ten months.

          safety protection

          DF-211 is weak acid. It should avoid contact with skin and eyes, and use a lot of water to rinse after contact.
