HS-717 Pickling corrosion inhibitor

Properties and uses

HS-717 Pickling corrosion inhibitor belongs to imidazoline products. When washing metal with acid, adding pickling corrosion inhibitor can inhibit the corrosion of steel by acid. The prerequisite for the application of acid cleaning corrosion inhibitor is that the cleaning medium is hydrochloric acid, sulfuric acid, and sulfamic acid, and the substrate to be cleaned is ferrous metal.

Pickling corrosion inhibitor HS-717 is suitable for pickling of various types of high, medium and low pressure boilers, as well as pickling of large equipment and pipelines. Corrosion performance in acid solution (dosage is 1-3‰) corrosion rate ≤1g/m 2 •h.

Usage

Add in the proportion of 1-3kg of pickling corrosion inhibitor in 5-10% hydrochloric acid per ton , mix and use, do not add the pickling corrosion inhibitor directly to the water; turn on the circulating pump to circulate for cleaning, and add it during the cleaning process When acid solution is added in proportion to the pickling corrosion inhibitor

Package and Storage

Normally In 25kg net Plastic Drum, IBC drum can also be used as required.Storage for 12 months in room shady.

Safety Protection

Avoid contact with eye and skin, once contacted, flush with water.

Main features and functions

High corrosion resistance rate

During the pickling process, the corrosion rate of the metal can be controlled at an extremely low level (such as ≤ 0.97 mm/year), and the corrosion inhibition rate can reach over 98%.

Protecting metals

Inhibit the hydrogen evolution reaction, prevent metal "hydrogen embrittlement", and inhibit the accelerated corrosion of trivalent iron ions, avoiding pitting corrosion (point corrosion).

Wide applicability

Suitable for various acids (hydrochloric acid, sulfuric acid, nitric acid, sulfamic acid, phosphoric acid, etc.) and various metals (carbon steel, stainless steel, copper, aluminum).
