CM-911 is a new type of solid pickling inhibitor, and another new achievement since the nitric acid inhibitor Lan-5 and multi-purpose pickling corrosion inhibitor Lan-826 were created.

Lan-826 multi-purpose pickling corrosion inhibitor technology is another invention after the nitric acid corrosion inhibitor Lan-5 technology, which is in the leading and unique position both at home and abroad. In 1984, it passed the technical appraisal of the Ministry of Chemical Industry, and in June 1985, it won the third invention prize of the State Science and Technology Commission.

Lan-826多用酸洗缓蚀剂技术，是继硝酸缓蚀剂Lan-5技术之后又一项发明成果，在国内外均处于领先和独有地位。一九八四年通过化工部部级技术鉴定，一九八五年六月荣获国家科委三等发明奖。

新型固体酸洗缓蚀剂CM-911技术是继硝酸缓蚀剂Lan-5技术和多用酸洗缓蚀剂Lan-826技术之后的又一项新成果，于一九九三年十二月通过省级鉴定，一九九六年荣获甘肃省科技进步二等奖。CM-911新型固体酸洗缓蚀剂系国内首创，达到了九十年代国际先进水平。
