Abstract
The invention relates to an electrolyte capable of removing oil and rust of metal surfaces. The electrolyte capable of removing the oil and rust of the metal surfaces is characterized in that every liter of the electrolyte comprises the following solid raw materials of 30-50 g of trisodium phosphate, 40-60 g of sodium nitrate, 10-20 g of hexamethylenetetramine and 100-120 g of potassium chloride. A preparation method of the electrolyte comprises the following steps that all the solid raw materials are dissolved in water, pH is adjusted to be one to two through hydrochloric acid with the concentration being 30%, and the electrolyte is obtained. The technique conditions are that the electric current is 5-9 A/dm2, and the time is 3-5 min. The electrolyte capable of removing the oil and rust of the metal surfaces has the characteristics that washing water after the electrolytic technique can be reused, discharging does not exist, the health of an operator is not influenced, heating is not needed, the effect that the oil and rust removing of the metal surfaces is simultaneously conducted in the same electrolyte at normal temperature is achieved, the raw materials are saved, the treating speed is quick, the cleaning effect is good, environment pollution does not occur, the effects of non-toxic and harmless are achieved, the method is simple, and cost is low.
Description
Art：
The present invention relates to metal phosphorizing, application, the pretreatment technology field of electroplating technology, more particularly to a kind of metal surface is removed
The electrolyte of oil rust cleaning.
Background technology：
At present, domestic and international metal pretreatment technology needs surface and oil contaminant, corrosion to eliminate, and can carry out phosphatization, application or plating,
Alkali cleaning oil removing is generally adopted, including chemical bases oil and electrolytic alkaline cleaning oil removing are removed, afterwards clear water is carried out to hardware
Rinsing, finally hardware is put in pickling tube carries out acid pickling and rust removing.And in acid cleaning process, due to waving by force for pickle
The property sent out, though production environment windowing ventilation, and be also to have little effect using forced-ventilated wind apparatus, its a large amount of acid mist for volatilizing, sternly
The service life of workshop miscellaneous equipment is have impact on again, the expense for making plant maintenance is continuously increased, operator need to be equipped with breathing mask,
Acidproof leather glove can work.Meanwhile, the clothes of the perishable operator of alkali lye, skin is difficult to cure after skin is corroded, because
This, to the health of operator serious threat is constituted.Metal works need pre-treatment to pass through application or plating after water is cleaned, and are produced
Raw discharge of wastewater causes the larger pollution in soil river.Particularly alkali and the waste liquid of acid do not have recovering mechanism, arbitrarily discharge, more pole
It is big to increase environmental improvement pressure.
The present inventor through repetition test research for many years, using electrochemical principle, allocated with water made by electrolyte, one
Secondary property solves the greasy dirt of metal surface, corrosion.
The content of the invention:
It is an object of the invention to provide a kind of electrolyte of metal surface degreasing and rust removal.
