The cleaning agent comprises the following main active ingredients in parts by mass: 1.65-111 parts of a nonionic surfactant, 1.25-115 parts of a zwitterionic surfactant, 12.6-152 parts of a complexing agent, 0.2-157 parts of a chelating agent and 2.25-131 parts of aids. The cleaning agent has wide applicability for the concentrated type multiple metals and nonmetals and synchronous multifunctional complexing property, over-corrosion of exterior of the metals is avoided and hydrogen embrittlement of interior of the metals is avoided, the cleaning agent is safe to use, three wastes are not produced, the resources are saved, and the environmental friendliness is achieved.
Description
Technical field:
The present invention relates to 1 of " Han Shi ecological circulation method "---7 (HC, HW, HM series product), the oil removing (only this can be used for nonmetal) of cleaning in metal and nonmetal surface treatment, rust cleaning, scale removal, phosphatization, passivation, anti-oxidation and antisepsis clean-out system, especially have concentrated type, recycle zero release, only lose the interior function without hydrogen embrittlement outward to metal; Realize a large amount of process waters and material, the reuse repeatedly of weakly acidic pH, toxicological harmless, safety, reprocessing cycle, energy-saving and water-saving, to economize on resources, without the multifuctional cleaning agent of the three wastes, no pollution, protection of the environment.
Background technology:
The many employings of cleaning that Surface Processing Industry is traditional:
1. oil removings:
(energy consumption is high, pollution is heavy for strong basicity hot solution, oil slick on working fluid surface causes secondary oil to pollute to processed part), or with strong acid, or with inflammable, explosive, virulent organic solvent, produce the toxic deep-etching heavily contaminated of the gas, liquid, solid three wastes.
2. rust cleaning:
Hydrochloric acid is used respectively according to different metal. nitric acid. sulfuric acid cleaned eliminates rust, generate toxic, the Huang of the people that chokes, red smog, produce serious corrodibility three-waste pollution, and the metal itself easily to cleaning part: outer dissolving forms excessive erosion, inside is oozed hydrogen and is produced hydrogen embrittlement, jeopardizes use safety, reduction of service life.
3. scale removal:
To the dirt of the pipe of a large amount of iron, copper, bar, tank and other metal products surfaces externally and internallies, adopt hydrochloric acid, nitric acid, sulfuric acid or other inorganic acid cleaning and descaling, produce serious three-waste pollution, simultaneously easy formation metal products outerly crosses erosion and inner hydrogen embrittlement, jeopardizes use safety, reduces work-ing life.
4. phosphatizations:
Use Toxic nitrite. nitrate. oxalate, and the many kinds of parameters chemically examining a large amount of phosphoric acid Phosphating Solution must be examined frequently, finally generate eutrophic three-waste pollution in serious murder by poisoning thing and water.
5. passivation:
The most chromic acid of toxic and salt thereof of adopting adds other inorganic acids, produces serious carcinogenic, heavy corrosion, toxic three-waste pollution.6. anti-oxidation and antisepsis:
Use ethanol. methyl alcohol is anti-oxidant, has again inflammable and explosive hidden danger to people is toxic, anticorrosion with benzotriazole, and in production technique, prominent moment of meeting hot metal, decomposites aniline. and oil of mirbane poisons thing, forms toxic three-waste pollution.
7. comprehensive: above-mentioned all kinds of difference two or more is multinomial, the product of comprehensive function plyability.
1---7 implement be all " treatment after pollution ", with the useless working fluid of useless rinse water dilution, again after repeatedly loaded down with trivial details process " qualified discharge ", to consume, loss great lot of water resources---form waste greatly and serious pollution hidden trouble, but people all take exception to! Therefore the fact causes virulent gas, liquid, solid three-waste pollution source, jeopardize workman's body and mind safety and Health, to production environment and equipment, deep-etching, heavily contaminated are formed to air, water and soil natural resources: bring disaster to watercourses, poison plough so that Fruit vegetables grain and oil crop is poisoned, transmutation of species, edible after cause youngster is infertile, neonatal is lopsided, cancer is multiple ethnic group by the disaster of ruining---within 2012, Cancer in China accounts for world's cancer half! The present invention eradicates above-mentioned severe corrosive heavily contaminated source, 1---the industrial production of 7 conventional metals nonmetallic surface cleaning industries, from source reform, the environmental protection industry creating recycling economy.
