What the present invention relates to is blackout (indigo plant) technology of the steel part in the metal surface treatment technology.
Steel part surface blackening technology is widely used in machinery, automobile, boats and ships, instrument, weapon manufacturing and the haberdashery and hardware industry.Traditional blackening is carried out in high-temperature concentrated alkali, and its technical process is as follows:
90 ℃ of alkali lye deoils → washes → and pickling → washing → 135 ℃ boil 30 to 60 minutes blackout → recovery liquid to 142 ℃ of high alkali liquids and wash → wash → boil oil in ℃ machine oil of saponification → 105 in 90 ℃ of soap solutions.
Therefore, oil removing blackout, the saponification of mechanical component, boil oil all at high temperature carry out, not only energy consumption is big for it, time is long, and production efficiency is very low, the volatilization of high-temperature concentrated alkali simultaneously causes the alkali mist to fill the air whole workshop, the severe contamination air, and workman's labor condition and production environment are very abominable.The late nineteen eighties, the research and development of domestic beginning room temperature blackening technology, but because the blackout film adhesion is low and the treatment process after the blackout, and make blackout workpiece corrosion resisting property poor, to making room temperature blackening technology can not replace conventional high-temperature alkalescence blackout and carrying out industrialized production.
Purpose of the present invention just provides a kind of metal blackening without the energy, with the high-temperature process in the normal temperature operation replacement traditional technology, is realizing without energy consumption, improve work efficiency, when improving workman's operational condition, the blackout workpiece corrosion resisting property height of acquisition, the effect of blackout rete strong adhesion.
Solution of the present invention is: by the metal normal temperature concentrated solution that deoils, metal normal temperature hair blackening liquid, the metal blackout normal temperature passivated confining liquid of workpiece or three operations without the energy of dehydration sealing oil are formed, and its detailed content is described below:
Metal normal temperature blackening without the energy of the present invention is characterized in that being made up of deoil concentrated solution, metal normal temperature hair blackening liquid, the metal blackout normal temperature passivated confining liquid of workpiece or three operations without the energy of dehydration sealing oil of metal normal temperature.The present invention mostly is mineral grease according to the greasy dirt that attaches in the mechanical part processing, and the overwhelming majority can not to generate soap water-soluble and break away from the characteristics of part with alkali generation saponification reaction in the mineral grease, it is big to have cancelled energy consumption, the halfway high-temperature alkaline oil removing of oil removing operation, the substitute is by tensio-active agent, emulsifying agent, permeate agent, wetting agent, complexing agent, multiple type material such as dispersion agent is formed the metal normal temperature concentrated solution that deoils, the concentrated solution that deoils of the present invention comprises fatty alcohol-polyoxyethylene ether, Triton X-100, sodium alkyl benzene sulfonate, trolamine sodium sulfate is tensio-active agent, their molecule is all by two genomic constitutions, one end be oleophilic group because of, with mineral oil good affinity is arranged, the other end be hydrophilic group because of, with water good affinity is arranged.In washing workpiece smeary process, the lipophilic group of these tensio-active agents is adsorbing oil molecule, and hydrophilic radical can make tensio-active agent well be scattered in the water, reach smeary purpose on the cleaning components, succsinic acid di-sec-octyl sodium sulfonate is a quickly penetrating agent, it can infiltrate through in the greasy dirt materials such as emulsifying agent in the degreasing fluid, dispersion agent, wetting agent under cold condition, speed deoiling speed.Water glass, tertiary sodium phosphate are emulsification, dispersion wetting agent, it makes on the part greasy surface tension reduce with tensio-active agent and is emulsified into little oil droplet, be distributed in the water, yellow soda ash is the auxiliary of degreasing fluid, its alkalescence can generate soap and be dissolved in water with the part grease, simultaneously, it and the water-disintegrable of tertiary sodium phosphate have shock absorption preferably at certain pH value of stablizing degreasing fluid.Sodium polyphosphate is except having emulsification, dispersion, wetting capacity, and therefore alkali and alkaline-earth metal ions in the solution of can also network living have softening of water, clean the effect of part.The over-all properties of above-mentioned materials shows less energy-consumption, high efficiency oil removing, degreasing, soil removability, they can guarantee the thorough cleaning of mechanical component pre-treatment, be to improve blackout film adhesion essential condition, this degreasing fluid is because basicity is moderate simultaneously, the aqueous solution of the water glass in the composition, tertiary sodium phosphate and sodium polyphosphate can generate the salt of insoluble with ferric ion, and the dissolving of retardance iron and steel has and plays rust inhibition when iron and steel soaked for a long time.
Metal normal temperature hair blackening liquid of the present invention includes copper sulfate, selenous acid (or tin anhydride), nitrate, OP-10, JBS-I, JBS-II and deionized water.Steel-iron components through activation treatment is put into the room temperature blackening liquid of dilution, piece surface at first produces displacement copper, in the time of replacement(metathesis)reaction, redox reaction takes place, promptly copper is oxidized to copper selenide by selenous acid, copper selenide is a ferrous metal, it is wrapped in the outside surface of steel-iron components, and the OP in the metal normal temperature hair blackening liquid component is a wetting agent, and the wetting piece surface of its energy everywhere, make it fully to contact hair blackening liquid, thereby obtain evenly blackout rete.The JBS-I, the JBS-II is a copper ion complexing agent, it can suppress the replacement reaction speed of copper iron, nitrate is that breaking of redox reaction sent out agent, their common effects are to guarantee that the speed and the copper iron replacement(metathesis)reaction of selenous acid cupric oxide are synchronous, to obtain the good copper selenide rete of bonding force, phosphoric acid in the component is regulated the pH value of hair blackening liquid, when pH value 3.5 when following, not only replacement(metathesis)reaction and redox reaction synchronism are good in the hair blackening liquid, and the bonding force of part blackout rete is also fine, every liter of stoste of metal normal temperature hair blackening liquid of the present invention is by copper sulfate 50 grams, selenous acid (or tin anhydride) 25-30 gram, nitrate 160 gram, phosphatase 24-8 milliliter, the OP3-5 milliliter, JBS-I 20 grams, JBS-II 15 grams and living ionized water are formed, and pH value is 1.5-2.Metal normal temperature hair blackening liquid of the present invention stable performance, standing storage is never degenerated, and does not lose efficacy, and this operation blackout time is short, improve nearly 10 times of work efficiency than conventional high-temperature alkali lye blackening, and in use non-volatile, non-stimulated smell, in the oil removing alkaline waste water of its acid waste water and pre-treatment and after, need not other processing, just can reach the emission standard of national waste water, environmentally safe can make Working environment and labor condition be greatly improved.
Metal normal temperature blackout part passivation confining liquid of the present invention is to aim at the postprocessing working procedures that the room temperature blackening part improves the corrosion resisting property design; also available dehydration sealing oil; the feature of passivation confining liquid comprises; polyvinyl alcohol; vinylidene chloride; formaldehyde; dichromate; hexamethylenetetramine; Sodium Benzoate; in solution, soaked 2-5 minute through the part after the acid blackout of normal temperature; can make the active chemical property of metal turn to passive state; the anodic process that has stoped metallic corrosion effectively; played good corrosion inhibition; also can produce simultaneously fine and close oxide film; be covered on the black film, deadened wet; oxygen contacts with part, has played the corrosion protection effect.Not through the acid part that turns black of the normal temperature of aftertreatment, because there is hole inevitably in film forming in acidic solution, perishable in air, do not reach the due decoration of blackening-protection purpose, operation behind the transpassivation sealing treatment, not only corrosion resisting property is improved greatly, and owing to contain water-soluble corrosion inhibitor in the passivation confining liquid component, making after the blackout part passivation sealing need not heat drying, just the blackout workpiece directly can be immersed cold machine oil as long as drain surplus liquid, simplify operating procedure, improve efficiency, saved the energy that the oven dry of heating is consumed, for condition has been created in industrial automation production.
Technical process of the present invention is as follows:
The metal normal temperature blackening of different energy sources provided by the invention, be widely used possessing also to have on the basis of above-mentioned performance, the part that every conventional high-temperature concentrated base can turn black, this technology is carried out equally smoothly, high carbon steel for the not so good blackout of traditional technology, cement steel parts, this technology adapts to equally, especially for containing manganese, metal alloy steel such as chromium, traditional technology some do not send out black, some can only obtain black film azury, does not satisfy export requirement, and adopts this technology can save a large amount of energy, can satisfy the foreign trader again requires and expands export and earn foreign exchange, accurate cast steel part quantity in foundry industry increases year by year, because its part wall thickness, weight is big, when adopting conventional high-temperature technology blackout, part is heated to 140 ℃ from cold, and power consumption is big, time-consuming length, often make part blackout weak effect because of heat up difficulty and difficult control of temperature, if adopt this technology, not only overcome above-mentioned shortcoming, and the cost 20-40% that also can descend.The present invention's facility investment in application is few, and whole process need not be heated, and the blackout process time is short, the 8-17% that has only traditional technology is because non-environmental-pollution needn't be installed exhaust equipment, this technology is corresponding one by one with each procedure of traditional technology, need not change equipment as long as transposing solution can be produced, it is little that technology provided by the invention in a word has investment, last detective adapts to extensively, and quality is good, cost is low, and the work efficiency height is easy to operate, the work situation health, the characteristics of non-environmental-pollution.
Process implementing of the present invention is simple, and when newly joining tank liquor, the deoil ratio of concentrated solution and water of metal normal temperature is 1: (6-10), when using for some time oil removal efficiency to descend, can add a little degreaser stoste.When the metal normal temperature hair blackening liquid was made into working fluid, a stoste added 8-10 part clear water and gets final product, and at this moment pH value is 2.5-3.When the black film blackness descends after working fluid is produced for some time, can replenish an amount of stoste, can keep ordinary production, metal blackout normal temperature workpiece passivation confining liquid can directly use, method is that the part with the blackout afterwash immerses in the passivation confining liquid, mention workpiece after 2-5 minute, drain surplus liquid, can reach the effect after the processing.Need if use, soak after also can turning black at workpiece → wash → neutralizing → wash in the dehydration sealing oil, reach effect equally without the energy.When the anti-corrosion performance that requires when workpiece substantially exceeds the part that the high-temperature alkaline blackening turned black, hair blackening liquid can be warmed up to 50 ℃ ± 5 ℃, film forming blackout part solidity to corrosion further improves under these processing condition, and substantially exceeds high-temperature alkaline blackout part.
