Description
Technical field
The present invention relates to a kind of clean-out system, particularly relate to a kind of environment-friendly degradable clean-out system and preparation technology thereof of safety non-toxic.
Background technology
The cleaning agent formula of current industrial use belongs to chemical agent formula mostly, belongs to highly basic, strong acid or leaning solvent.Have following shortcoming during use: when 1) using, security is inadequate, liquid has corrosive nature to cleaning material surface, and toxic to human body, some clean-out system is inflammable and explosive; 2) comparatively large to the damage ratio of environment, there is biological accumulation to endanger to air, water resources; 3) cleaning performance is lower, and life cycle is short; 4) remained on surface or uniform passivation.
For metal wire-drawing industry, the agent of original use pickling, advantage is can fast decontaminating, but shortcoming is more, such as not environmentally, can not discharge, soiling solution is administered and needs expensive fund, be corrosive to metal, for cleaning workman, pickling agent is corrosive simultaneously, the larger harm of generation is known from experience to people, be infected with on skin or on eyes because of carelessness, cleaning workman burn can be made, so country's present stage has ordered forbid that metal wire-drawing industry uses pickling agent.
And the waterborne cleaning agent recently researched and developed also is based on chemical agent, and adopt base formulation, containing to be harmful to physical environment and human body or to need the long period could the material of natural degradation in its formula more.
Patent Office of the People's Republic of China and on January 26th, 2005 disclose the patent of invention of a kind of water-solubility printing ink washing agent and preparation technology thereof, patent No. 03119639.X, this technical scheme have employed the water-soluble washing agent that the component such as polyoxyethylene octyl phenolic ether or polyoxyethylene nonylphenol ether, trolamine, ethylene glycol butyl ether, soft water is made.Its weak point is, can cause the murder by poisoning to human body and environment.
Summary of the invention
The object of the invention is to be harmful to physical environment to solve existing water-soluble washing agent or to need the long period could the material of natural degradation, can cause and provide a kind of predicament in order to change the pickling of metal wire-drawing industry, the environment-friendly degradable clean-out system of safety non-toxic to the defect of the murder by poisoning of human body and environment.
