Abstract
The invention discloses a process for quickly cleaning the surface of a nickel coated steel bollet. The process is characterized by comprising the following steps: putting the nickel coated steel billet in a cleaning agent consisting of a cleaning agent A, a cleaning agent B, alcohol, a WA dehydrating agent and water, wherein the cleaning agent A consists of sodium stearate, sodium oleate, polyoxyethylene nonyl phenyl ether, sodium silicate, borax and alkylolamide, and the cleaning agent B consists of trimeric sodium phosphate, AEO9, sodium alkyl benzene sulfonate and glauber salt; and producing a clean billet cake by rinsing by deionized water, blowing by compressed air and drying by hot air. The process replaces the prior acid cleaning process, can quickly remove oil stains and nickel scraps on the surface of the billet, so the clean surface of the billet can be directly stamped so as to improve the lustrousness and appearance quality of the surface of the billet, and further reduce the labor intensity and production cost.
Description
Technical field
The present invention relates to coin manufacturing technology field, specifically a kind of process for rapidly cleaning surface of nickel-coated billet cake.
Background technology
At present, increase the base cake in the coin manufacturing and rolled word technology, in rolling the word production process, base cake edge is squeezed, and the metallic nickel plated layer of coin blank cake can come off on a small quantity, be subjected to secondary pollution in the base cake course of processing simultaneously, make base cake surface have a small amount of rubbish, nickel bits and greasy dirt, directly impress, then can cause the quality problems of the sticking nickel of impression as the base cake, existing manufacturing technique is rolling word after pickling, alkali cleaning and rinsing, to reach the purpose of base cake cleaning surfaces.Because acid cleaning process, equipment are more outmoded, there is potential safety hazard in operator's working strength, especially manual operation than higher during operation, the difficult control of processing parameter, cause quality product fluctuation bigger, and bronsted lowry acids and bases bronsted lowry all has corrosive nature to base cake surface, reduced the work-ing life of base cake, the base cake is after overpickling simultaneously, surface gloss reduces, and makes the base cake surface obfuscation behind the impression, influences base cake surface quality.
Summary of the invention
A kind of process for rapidly cleaning surface of nickel-coated billet cake of providing at the deficiencies in the prior art is provided, adopt the cleaning of soapless soap to replace former pickling technology, it can Rapid Cleaning remove rubbish, greasy dirt and the nickel bits on base cake surface, base cake cleaning surfaces can directly be impressed, glossiness, visual appearance and the work-ing life on base cake surface have been improved, it is convenient to have production of detergents, and cleaning is simple, greatly reduces labour intensity and production cost.
The concrete technical scheme that realizes the object of the invention is: a kind of process for rapidly cleaning surface of nickel-coated billet cake, characteristics are nickel-coated billet cake to be put in the washings clean, clean after rinsed with deionized water, pressurized air vibration are blown down, warm air drying becomes cleaning base cake, wherein: washings is mixed by washing composition A, washing composition B, alcohol, WA dewatering agent, water, is specifically undertaken by following step:

C. getting above-mentioned washing composition A:20g, washing composition B:30g, 90% alcohol 400ml, WA dewatering agent 30ml, water 200L Hybrid Heating, to become temperature be 60 ℃ washings.
Acting as of its main component of washing composition A: sodium stearate is an emulsifying agent, has the cleaning performance of low irritant gentleness; Sodium oleate is that the emulsifying agent wetting ability is stronger, and is soluble in water, and very strong cleaning force is also arranged, and can be used as emulsifying agent and uses; Polyoxyethylene nonylphenol ether has that a plurality of ether wetting abilities are very strong, soluble in water, and the emulsification dissemination is better, very strong cleansing power; Water glass is a cleaning additive, can make water softening, and throw out easily floats and removes, and the soil suspension effect is better, prevents that dirt from adhering to again; Sodium sulfate is cleaning additive, reduces the surface tension of scavenging solution and the interfacial tension between the profit, improves the solublization of scavenging solution; Yellow soda ash is cleaning additive, can make water softening; Borax: can play shock absorption to soda acid, but softening of water with the synergy such as tensio-active agent in the clean-out system, also can improve the free-flowing property of powdery clean-out system, prevents caking; Alkylol amide is a clean-out system, and decontamination, degreasing effect are good, and adding its washing effect in the prescription significantly increases.Clean-out system A has emulsifying property and dispersiveness preferably, and is better in solvability more than 60 ℃, but the soil suspension performance is relatively poor relatively to chelation of metal ion.
Acting as of its main component of washing composition B: tripoly phosphate sodium STPP is the inorganic surfaces promoting agent, the ability that stronger complexation of metal ions is arranged, generate soluble complexes with metal ion, can make the hard water deliquescing, has very strong shock absorption, the PH of washing composition is remained on than in the optimum range, solia particle there is stronger dispersion force, can prevent redeposition with the washing composition adapted, can significantly reduce surface tension of liquid or two-phase interface tension force, increase the perviousness of washing composition,, more increased the washing of oil-containing dirt is renderd a service to greasy emulsifying effect and to proteinic swelling and solublization; AEO
9[C
12Aliphatic alcohol polyethenoxy (9) ether] be nonionic surface active agent, have excellent biodegradability and low-temperature performance, be not subjected to the influence of the water hardness, scourability is good; Linear alkylbenzene sulphonic acid is soluble in water, has good detersive power, seepage force and foaming power, and comprehensive scourability is superior; Saltcake can reduce the surface tension of scavenging solution and the interfacial tension between the profit, improves the solublization of scavenging solution.Clean-out system B has remedied clean-out system A and has lacked the chelating of heavy metal ion and the defective of dispersive ability.
Alcohol can be accelerated the volatilization of base cake surface moisture content.
The WA dewatering agent can form one deck hydrophobic membrane at originally hydrophilic workpiece surface, can remove the moisture content of metallic surface rapidly, improves water stain that workpiece forms when drying, makes the workpiece purpose of dehydration rapidly thereby reach.
(2), clean
Above-mentioned washings is put into the rinse bath of coin cleaning machine with nickel-coated billet cake 400Kg, stainless shot 800Kg, cleaned 3 minutes, what its cleaning process was a washings to the base cake is wetting, makes dirt softening, loose, in addition in mechanical stirring, make stainless shot fully contact and rub, rely on the emulsifying effect of washing composition, disperse dirt base cake surface, form fine particle, and be suspended in equably in the washings, be dissolved in even in the washings, make dirt break away from the base cake fully.
(3), rinsing
Base cake after the cleaning relies on the flushing of clean current with 80 ℃ rinsed with deionized water 7 minutes, and the washings of dirt is washed away from the base cake.
(4), drying
The pressurized air of base cake after the above-mentioned rinsing in the vibrating machine of band air knife was blown down 6 minutes, then through dry 5 minutes of spiral hot air dryer the nickel-coated billet cake of cleaning, will clean the base cake and send the impression operation.
Cleaning of the present invention has replaced acid cleaning process of the prior art, it removes rubbish, greasy dirt and the nickel bits on base cake surface by the Rapid Cleaning of automatization, base cake cleaning surfaces can directly be impressed, improve work-ing life, surface luster and the surface quality of base cake, reduce labour intensity and production cost.
