Problems solved by technology

[0002] For pipelines that have been used for a long time, the solidification of oil sludge and rust in the pipeline will cause the diameter of the original pipeline to become smaller, and the sludge in the pipeline will produce hydrogen sulfide gas, which will cause environmental pollution and easily cause explosions; the acid and alkali substances in the wastewater will easily corrode the pipeline; Unscheduled removal of foreign matter can cause pipe blockage
[0003] In the past, most of them used mechanical cleaning. During the cleaning process, they would cause damage to the pipeline and cause irreparable losses. Now chemical cleaning is gradually used. Chemical cleaning has the characteristics of no requirement for the shape of the pipeline, fast speed, clear and thorough

Abstract

The invention discloses a sewer line cleaning agent composed of raw materials by weights: 5 to 10 parts of ammonium hydroxide, 1 to 5 parts of lipase, 20 to 30 parts of triammonium citrate, 14 to 17 parts of chloroform, 11 to 14 parts of EDTA (Ethylene Diamine Tetraacetic Acid), 8 to 13 parts of potassium hydroxide, 3 to 9 parts of gluconic acid sodium salt, 6 to 15 parts of polycarboxylate superplasticizer, 5 to 10 parts of surface active agent, 8 to 12 parts of corrosion inhibitor, 1 to 10 parts of penetrating agent, 100 to 200 parts of water. The surface active agent includes, by volume, 10to 50% of polyglycol ether, 10 to 50% of butyl cellosolve and 40 to 70% of ammonium oxide. The corrosion inhibitor includes, by volume, 3 to 8% of phosphonic acid, 10 to 30% of polyaspartic acid, 40to 60% of sulfonation lignin and 20 to 40% of benzotriazole. By adopting the above method, dirt and grease in a line can be removed effectively, the cleaning effect is good and cleaning waste water discharge standards can be met.
