Corrosion
Inhibitor for Hydrochloric
Acidic Cleaning
Properties and Usage:
This product is a kind of imidazoline corrosion inhibitor, it can effectively inhibit steel corrosion. The precondition for use of this product is that the cleaning agent is hydrochloric acid, sulfuric acid and sulfaminic acid, and the cleaning object is black metal. This product is suitable for acidic cleaning of all types of high, medium and low pressure boiler, large scale of equipment and pipeline. When the dosage is 1-3‰, the corrosion ratio will be lower than 1g/m2?h.
Specification:
| Items | Index |
|---|---|
| Appearance | Umber transparent liquid |
| pH (as it) | 6.0-8.0 |
Usage:
For 5-10% hydrochloric acid solution, add 1-3kg of this product per ton and mix well. This product cannot be added into water directly. During the process of acidic cleaning, power on circulating pump and add this product accordingly.
Package and Storage:
200L plastic drum, IBC(1000L),customers’ requirement. Storage for ten months in shady room and dry place
