SPJ-6650 corrosion inhibitor for water treatment

1.Good effect in preventing condenser fouling and corrosion 2.Good dispersion for iron oxide 3.Good compatibility

SPJ-6650 anti-incrustation corrosion inhibitor is mainly used for open re-circulating cooling water system in electricity and steel industry, especially in electricity industry. It is mainly applied to medium-hardness, medium-alkalinity water. It has good effect in preventing condenser fouling and corrosion. Users need to adjust the formula proportion to apply to water system under different conditions.

SPJ-6650 is composed by cooper corrosion inhibitor, organic phosphoric acid, phosphonic acid and high polymer. It has good corrosion inhibition, good dispersion and threshold effect. This product is organic. The product has a good dispersion for iron oxide at the same time to prevent CaCO3,Ca3(PO4)2 and CaSO4 becoming scale and precipitate. The product can be used for the system contains cooper, carbon steel and stainless steel. It can form a thin and dense anti-corrosion film on the metal surface at a high pH. It has the advantage of forming film fast, making up membrane well, operating safe and good compatibility.

Usage

The product is liquid, could be added continuously by pump. According to the water feature and the devices, the general dosage is 5-20ppm. The concentration of SPJ-6650 in circulating system should be controlled based on the total phosphorus. Our engineers can service on-site to confirm the right dosage and add locations.

Packing and storage

       1.It should be kept in cool, ventilated warehouses. Guaranty period: one year.

       2.The product is acid, so it can’t mix-use with strong alkaline, oxidizing, reducing substances. Users should wear personal protective equipment such as: rubber gloves, goggles, gas masks and chemical aprons when use the product. The product should be sealed when not in use.
