Zero-emission metal and nonmetal surface cleaning agent with effects of oil removal, rust removal, scale removal, phosphorization, passivation, oxidation resistance and corrosion prevention

Abstract

The invention discloses products of a Han ecological cycle method from the first to the seventh (HC, HW and HM series products) and relates to a recycled zero-emission metal and nonmetal surface multifunctional cleaning agent with effects of oil removal (used for nonmetals only), rust removal, scale removal, phosphorization, passivation, oxidation resistance and corrosion prevention. 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: [0001] The present invention relates to 1-7 of "Han's Ecological Cycle Method" (HC, HW, HM series products), oil removal (only applicable to non-metal), rust removal and scale removal in cleaning of metal and non-metal surfaces , phosphating, passivation, anti-oxidation and anti-corrosion cleaning agents, especially with the functions of concentrated type, zero discharge for recycling, no corrosion on the outside of the metal and no hydrogen embrittlement inside; realize a large amount of industrial water and materials, near neutral, non-toxic , safety, regeneration and repeated reuse, energy saving, water saving, resource saving, no three wastes, zero pollution, multifunctional cleaning agent for environmental protection. Background technique: [0002] The traditional cleaning process in the surface treatment industry mostly uses: [0003] 1. Degreasing: [0004] Strong alkaline hot solution (high energy consumption, heavy pollution, and the oil slick on ...

Problems solved by technology

[0015] Parts 1 to 7 are all implemented "pollution first and then treatment", diluting the waste working fluid with waste cleaning water, and then "discharging up to the standard" after many times of tedious treatment, consuming and losing a large amount of water resources - forming a huge Waste and serious pollution hazards, but people don't take it seriously! Therefore, the facts have caused toxic gas, liquid, and solid waste pollution sources, endangering the physical and mental safety and health of workers, causing strong corrosion and heavy pollution to the production environment and equipment, and to the atmosphere, water, soil and n
