针对目前除锈工艺存在的缺点和不足,淮北矿务局科研所欧阳应发同志对钢铁表面的除锈工艺进行了深入的研究,发明了“钢铁除锈钝化新工艺”。这项新工艺的特点在于采用一种专门研制的含活化剂的盐酸除锈液和生石灰、亚硝酸钠的钝化液,对钢铁表面进行处理。除锈 In view of the shortcomings and deficiencies of the current descaling process, Ouyang Yingfa, a research institute of Huaibei Mining Bureau, conducted an in-depth study on the derusting process of the steel surface and invented the “new process of steel derusting and passivation.” The new process is characterized by the use of a specially developed activator-containing hydrochloric acid and lime quicklime, sodium nitrite passivation solution, the steel surface treatment.
