Txoj kev ntawm electroplating yog dab tsi?
Electroplating yog muab faib ua khib plating, chim plating, nruam plating, thiab txhuam plating, uas yog feem ntau muaj feem xyuam rau qhov loj thiab batch ntawm cov khoom yuav plated.
Khib plating yog tsim rau cov khoom ntawm qhov ntau thiab tsawg, xws li tsheb bumpers, tsheb kauj vab handlebars, thiab lwm yam. Barrel plating yog haum rau me me qhov chaw, xws li fasteners, washers, pins, thiab lwm yam. Nruam plating yog haum rau batch zus tau tej cov xov hlau thiab strips. Txhuam plating yog tsim rau ib nrab plating lossis kho. Cov tshuaj electroplating muaj xws li acidic, alkaline, thiab acidic thiab nruab nrab daws nrog chromium sib tov. Tsis muaj teeb meem dab tsi yog siv txoj kev plating, lub plating tso tsheb hlau luam thiab hangers nyob rau hauv kev sib cuag nrog cov khoom yuav tsum tau plated thiab cov plating tov yuav tsum muaj ib tug tej yam degree ntawm Versatility.
Txheej txheej:
Cov txheej txheej tau muab faib ua ob hom: zoo nkauj tiv thaiv txheej thiab ua haujlwm txheej.
Kho kom zoo nkauj tiv thaiv txheej: feem ntau chromium-plated txheej ntawm ferrous hlau, non-ferrous hlau, thiab yas, tshwj xeeb tshaj yog tooj liab-nickel-chromium txheej ntawm hlau, thiab nickel-chromium txheej ntawm zinc thiab hlau. Yuav kom txuag tau tus pin pogo, tib neeg tau tuaj yeem ua cov phaj tooj liab-nickel / hlau-high-sulfur nickel-nickel / hlau-tsawg cov khoom nickel-chromium txheej ntawm cov hlau. Cov tin / npib tsib xee txheej zoo ib yam li cov chromium txheej tuaj yeem siv rau kev ntsuas ntsuas, tshuaj twj, li qub, thiab ntsuas ntsuas ntsuas.
Muaj ntau ntau hom kev ua haujlwm txheej, xws li:
①Plating txheej ntawm zawv zawg bearing npog los txhim kho kev sib raug zoo thiab embedding nrog phau ntawv, lead-tin, lead-tooj liab-tin, lead-indium, thiab lwm yam coatings;
②Nws yog siv rau tawv chromium txheej ntawm hnav-resistant nruab nrab thiab siab ceev diesel cav piston nplhaib. Cov txheej no tseem tuaj yeem siv rau ntawm cov pwm yas, thiab muaj cov yam ntxwv ntawm cov pwm uas tsis yog-stick thiab ua haujlwm ntev;
③Plating tooj liab ntawm zawv zawg saum npoo ntawm lub pob zeb loj loj tuaj yeem tiv thaiv qhov zawv zawg nto los ntawm kev tuaj tos ntxov;
④ Galvanizing siv los tiv thaiv cov hlau substrate los ntawm corroded los ntawm cua;
⑤ Copper-tin txheej los tiv thaiv nitriding;
⑥ Tin-zinc txheej siv rau brazing hauv kev tsim cov xov tooj cua thiab TV los tiv thaiv corrosion ntawm galvanic hlwb ntawm hlau thiab txhuas.
Cov txheej txheem engineering tsim nyog rau kev kho thiab tsim khoom suav nrog chromium, nyiaj, tooj liab, thiab lwm yam, thiab lawv cov tuab kuj loj, thiab cov tawv chromium txheej tuaj yeem tuab li 300 microns.
Cov txheej txheem electroplating yog qhov tseem ceeb raws li hauv qab no:
1 Txuas cov hlau plated rau lub anode
2 Txuas lub plated ib feem rau lub cathode
3 Lub anode thiab cathode txuas nrog cov tshuaj electrolyte uas muaj cov ions zoo ntawm cov hlau plated
4 Tom qab siv hluav taws xob ncaj qha tam sim no, cov hlau ntawm lub anode yuav raug oxidation cov tshuaj tiv thaiv (tsawg electrons), thiab cov ions zoo hauv cov tshuaj yuav raug txo kom tsawg ntawm cathode (tau electrons) rau hauv atoms thiab sib sau rau ntawm qhov chaw qhov tsis zoo electrode.
Tom qab electroplating, qhov zoo nkauj ntawm cov khoom electroplated muaj feem xyuam nrog qhov loj ntawm qhov tam sim no. Qhov me me tam sim no, qhov zoo nkauj dua cov khoom electroplated yuav yog; txwv tsis pub, qee cov duab tsis sib xws yuav tshwm sim.
Lub hom phiaj tseem ceeb ntawm electroplating muaj xws li kev tiv thaiv hlau oxidation (xws li xeb) thiab kho kom zoo nkauj. Cov txheej txheej ntawm ntau npib kuj yog electroplated.
Cov dej phwj tuaj ntawm electroplating (xws li cov electrolytes tsis zoo) yog qhov tseem ceeb ntawm cov dej paug.
