Abstract:
     The present invention is a phosphoric cleaning agent and its preparation. The agent is composed of phosphoric acid, sodium ethyldiaminetetraacetate tetrabasic, corrosion-inhibitive agent A, cleaner Tx-10 and water. It is suitable for washing rust and greasy dirt on the surface of steel products, especially for lustering metal surfaces in the inner wall of steel tube. Compared with similar product, cleaner NEOSPC 400 manufactured by Japanese NEOS Co., this cleaning agent has a simple performance, a halved corrosion-slowing rate and a halved hydrogen brittle coefficient,and it also saves energy and water.
