The invention has the characteristics of low working temperature, high processing speed, favourable processing effect, energy conservation, environment protection and the like.
Description
Technical field
The present invention relates to a kind of method of differential of arc on metal surface clean, belong to metal surface treatment technology.
Background technology
Metallic surface according to the invention clean mainly is meant the dirt impurity of removing the metallic surface, recovers the original looks in metallic surface.
The method of metallic surface clean, using general at present is to adopt the method that rust cleaning oil removing sanitising agent cleans and water rinses mostly.And used sanitising agent adopts for example sulfuric acid and highly basic chemical substance such as sodium hydroxide for example of strong acid, mostly via forming with other chemical substance is composite.This clean effect by the composite sanitising agent that forms of number of chemical material is generally all fine; But its cleaning surfaces process is very big to the influence of environmental protection, the safety of going back the entail dangers to human body sometimes; And the metallic surface after clean can receive more serious corrosion.Thereby to some metallic article products such as non-ferrous metal copper, aluminium, zinc for example, the spinoff that is caused, be people do not hope to see.Chinese patent publication number CN101215714, CN101634031 and CN10133364 etc. have used acid and organism, and its process for preparation is complicated, and production efficiency is low, and production cost is high, and production environment is poor, and three waste discharge is handled and relatively is hard on.Thereby, provide a kind of production efficiency high, production cost is low, and the method for the metallic surface clean of Environmental Safety just becomes expectation in the industry.
Summary of the invention
The present invention aims to provide a kind of method of differential of arc on metal surface clean, to overcome the deficiency of prior art.
The present invention realizes that the technical though of its purpose is, adopts electrolysis principle, in the treatment solution of electrolyzer; With metal to be treated spare is negative electrode; With the stainless steel product is anode, between said cathode and anode, applies certain voltage, makes and produces little arc-over on metal to be treated spare and the treatment solution interface; By the surface of the differential of the arc cleaning metal to be treated spare that is produced, thus the purpose of realization differential of the arc clean.
Based on above-mentioned technical though, the present invention realizes that the technical scheme of its purpose is:
A kind of method of differential of arc on metal surface clean; This method is in the treatment solution in electrolyzer, is negative electrode with metal to be treated spare, is anode with the stainless steel product; Between said cathode and anode, apply certain voltage; Make and produce little arc-over on treatment solution and the metal to be treated spare interface, by the differential of the arc that is produced clean is implemented on metal to be treated spare surface, its innovative point is:
The weight percent of a, said treatment solution component and component is: oxyhydroxide 5～10%, and carbonate 5～10%, halogenide 5～10%, water 70～80%,
B, said processing current density are at 1～20A/dm
2In the scope;
The time of c, said clean is in 1～10min scope.
Can understand by above-described technical scheme; The present invention is because the treatment solution that it adopted is weakly alkaline; And the weakly alkaline treatment solution to can not causing the threat that is corroded in the metallic surface, and adopts electrolysis principle; The differential of the arc of utilizing metal to be treated spare and treatment solution interface to be produced is cleared away the greasy dirt, oxide compound and other impurity that are present in the metalwork surface.Thereby its treatment effect is good, and production efficiency is high, and processing cost is low, production scene three-waste free discharge and Environmental Safety, thus realized the object of the invention.
The said oxyhydroxide that the present invention advocated is sodium hydroxide or Pottasium Hydroxide; Said carbonate is yellow soda ash or salt of wormwood; Said halogenide is sodium-chlor or Repone K, and said water is zero(ppm) water or deionized water.The said oxyhydroxide that the present invention advocated, carbonate and halogenide all are the industrial chemicals of using always, their stable chemical performance, people are to be familiar with grasping, thereby do not have potential safety hazard basically their use and management process.Certainly, said three kinds of chemical substances are preferred for this invention, do not get rid of and adopt other oxyhydroxide, carbonate and halogenide.
The present invention also advocates, its work of treatment temperature＜50 ℃.This is that the present invention passes through repeatedly to test repeatedly institute preferably.Has very high cost performance.In fact, the work of treatment temperature is high, metallic surface clean effective, and the time of processing is shorter, but will consume the required energy of heating.The special opinion of the present invention is implemented the clean of metallic surface at normal temperatures.
After technique scheme was able to implement, the technology that the present invention had was simple and easy to control, and treatment effect is good, and production efficiency is high, and processing cost is low, and characteristics such as Environmental Safety are conspicuous.
