PHOSPHONIC ACID/PHOSPHATE MIXTURE FOR SUPPRESSING METAL CORROSION AND PRECIPITATION OF CALCIUM PHOSPHATE |
| 摘要 |
<p>A method of controlling the corrosion of a metal surface in contact with an aqueous system while at the same time preventing the precipitation of potentially scale-forming calcium salts such as calcium phosphate, comprises treating the system with a source of orthophosphate ion and a mixture of methylene phosphonic acid derivatives of C6 diamines, or the salts thereof.</p> |
