Package: Plastic drum or iron drum

Uses : hydrochloric acid inhibitor, prevent the device from pitting

Product description: Nature： Appearance: palm red liquid Density（20℃）g/cm3: 0.80~0.90 Viscosity（25℃）m Pa•S: 1.2~2.0 PH: 3.0~4.0 Feature： Efficient inhibition performance acidic corrosion inhibitor, it will enable the rusty steel materials in 5% hydrochloric acid pickling rust process can still protecting the substrate metal from acid etching. The feature is that the carbon steel after pickling can not only bright as a new but also eliminate the phenomenon of hydrogen embrittlement in carbon steel pickling process. This is particularly important for equipment and components which has stress state，as it can avoid deteriorating effect of mechanical property which is damage to the material in pickling process. In the hydrochloric acid of add pharmaceutical, pickling electroplated parts before it plated, can overcomes and improve the stress brittle fracture and coating cracking of plated parts which is due to hydrogen permeation. Purpose： 1. Can be used as Hydrochloric acid inhibitor in boilers, machinery, metallurgy and electroplating industry. 2. In the circulating cooling water system, adds the NC-2mg / L can effectively prevent the device from pitting. Usage： After add this pharmaceutical (0.2 to 1.0)% in 5% hydrochloric acid, pickling carbon steel materials and its equipment and parts below 60℃. Inhibition rate can up to 95% or more, simple to use, and non-toxic. When hydrochloric failure, can continue to add 5% hydrochloric acid. At that time, the product can not be added or little me\ore added. In the circulating cooling water system, add the NC-6 can effectively prevent the device from pitting. Packaging and Storage: 25KG plastic drum or 160KG iron drum. Store in a cool room, storage for ten months.
