Abstract

The invention discloses a water-free metal surface treatment process which comprises the following step that deoiling and descaling are conducted through strong acid, and mechanical equipment, a chemical agent and a surface cleaning agent xs-501 (up to standard of Rohs of the European Union) are used, specifically, a solution is prepared by mixing 5% of xs-501 with 95% of water at the temperature of 50-65 DEG C, the effect of removing impurities including greasy dirt on the surface of a workpiece can be achieved by using the solution, an ultrasonic filter device is recycled, the surface of the cleaned workpiece is blown-dried through wind shear when the cleaned workpiece stays in the air, and no chemical agent or water is drained. Since no chemical agent or water is drained, and environment protection requirements are completely met, the water-free metal surface treatment process is currently known internationally as a cleaning mode with a better effect, the cleaning efficiency is improved, no requirement for production fields and staff exist, and the consumption cost is lowered.

Description

One exempts from water metal surface treatment process

Technical field

Present invention relates particularly to one and exempt from water metal surface treatment process, belong to metal treatment art.

Background technology

Present metal surface treatment technology：Three acid (using strong acid oil removing, descale) → drift ice → drift ice → chromic anhydrides go out light → drift ice → drift ice → drift ice → passivation → drift ice → drift ice.

Therefore present metal surface treatment technology suffers from the drawback that：

1st, three acid (nitric acid, sulfuric acid, hydrochloric acid are stopped using) cleaning, has strong oxidizing property and (cleans product often rotten Erosion), and there is strong volatility, it is easily decomposed into poisonous oxynitrides, big to environment, air pollution, water processes extremely difficult, place Reason cost is high, has spread effect and corrosivity to human respiratory.If sucked by human body, the lighter causes sphagitis, pulmonary emphysema, exhales Inhale difficulty, suck and excessively may result in death.

2nd, chromic anhydride goes out light technique (country prohibites use), and in chromic anhydride, heavy metal Cr VI (does not also find to it at present Effective processing method) there is extremely strong strong oxidizing property, the toxicity of chromic anhydride is relatively big and has highly acid and corrosivity, its concentrated solution Can corrode major part metal when high temperature, weak solution also can be damaged string, make leather brittle.Chromic anhydride is strong oxidizer, Its aqueous solution dichromic acid can decompose to give off oxygen at normal temperatures, destroys vegeto-animal tissue.Can cause human body acute poisoning, suction can Cause respiratory tract, nosebleed, hoarseness, Atrophic nasal mucosas it sometimes appear that asthma and cyanosis, oral stimulation and corruption Erosion alimentary canal, cause nauseating, suffer from abdominal pain, have blood in stool；Serious expiratory dyspnea, cyanosis, shock, hepatic injury and acute renal failure. There is environmental hazard, water body can be polluted.Chromic anhydride also has combustion-supporting property, high toxicity, carcinogenicity, highly corrosive.

3rd, water consumption is big, and ineffective any method processes product, will rinse with overflow water, is greatly increased the pressure that water is processed Power, currently the majority is all to arrange steathily, to river, river, lake, underground water pollution very big.

4th, power consumption is big, and the product having processed water to be blown is dried, and drying plant has used electricity, combustion gas, coal etc. in a large number.

Content of the invention

The technical problem to be solved in the present invention overcomes existing defect, provides one to exempt from water metal surface treatment process, nothing Medicament discharges, and anhydrous discharge complies fully with environmental requirement, is the current generally acknowledged more preferable cleaning way of effect in the world, and equipment becomes This and consuming cost are low, and without expenses of environmental protection, improve work situation, alleviate labour intensity, improve cleaning efficiency, to life Produce place and personnel's no requirement (NR), reduce consuming cost, can effectively solve the problem in background technology.

In order to solve above-mentioned technical problem, the invention provides following technical scheme：The present invention provides one to exempt from water gold Metal surface processes technique, comprises the following steps：(1) strong acid oil removing, descale, are used；Utilize plant equipment and chemical agent, table Face cleaning agent xs-501 (European Union Rohs) using method：Xs-501 fluting 5%, water 95%, temperature 50 C-65 DEG C just reaches to remove The effect of the impurity such as surface of the work greasy dirt, ultrasonic wave has filter, recycles, when the workpiece after cleaning stays aloft, Have wind to cut surface of the work is dried up, without medicament discharge, anhydrous discharge；(2), clean；Chemical agent, surface cleaning agent xs-505B (European Union Rohs), using method：Xs-505B slots 30%xs-505A10% water 60% temperature, normal temperature, recycles, after cleaning Workpiece when staying aloft, have wind to cut and surface of the work dried up, without medicament discharge, anhydrous discharge；(3), clean；Chemical drugs Agent, surface cleaning agent xs-505A (European Union Rohs), using method：Xs-505A fluting 90%, xs-505B10%, temperature, clean During have intensification, cooling system to be had, control at about 35 DEG C, recycle, when the workpiece after cleaning stays aloft, Have wind to cut surface of the work is dried up, without medicament discharge, anhydrous discharge；(4), clean；Chemical agent, surface cleaning agent xs-505C (European Union Rohs), using method：Xs-505C fluting 10%, temperature, normal temperature, recycle, the workpiece after cleaning stays aloft When, there is wind to cut and surface of the work is dried up, without medicament discharge, anhydrous discharge；(5), clean；Chemical agent, surface cleaning agent xs- 502 (European Union Rohs), using method：Xs-502 fluting 10%；Temperature, normal temperature, recycle, the workpiece after cleaning stops in the air When staying, there is wind to cut and surface of the work is dried up, be more uniformly sprayed onto surface of the work with dry-steam, substitute drift ice function, without medicament row Put, anhydrous discharge；(6), dry, be uniformly sprayed onto surface of the work for 2 times with dry-steam, substitute drying function, no drying room, dry Line.

Preferably, the steam temperature in step (7) is 180 DEG C.
