CHROMING
Chrome plating, feem ntau hu ua chromium plating lossis hard chrome, yog ib txoj kev siv electroplating ib txheej nyias ntawm chromium rau ntawm cov khoom hlau. Cov txheej txheem chromium plating ntawm cov raj honed thiab chrome rods yog ib qho txheej txheem kho qhov chaw tsim los txhim kho kev hnav tsis kam, kev tiv thaiv corrosion thiab kev zoo nkauj ntawm cov khoom no. Chrome plating muab ib qho chaw nrog kev nyuaj siab thiab coefficient qis ntawm kev sib txhuam, uas yog qhov tseem ceeb rau cov ntsaws ruaj ruaj hauv cov tshuab hydraulic. Cov hauv qab no yog cov kauj ruam dav dav ntawm cov txheej txheem chromium plating rau cov raj honed thiab piston rods:
rub tawm daim ntawv teev khoom
1. Kev Ntxuav: Ua ntej, lub raj honed thiab chrome pas nrig yuav tsum tau ntxuav kom huv si kom tshem tawm tag nrho cov roj, xeb, thiab cov khoom tsis huv, thiab lawv qhov kawg yuav tsum tau npog.
2. Tshem cov roj: Siv cov tshuaj lom neeg lossis cov txheej txheem kho tshuab kom tshem tawm cov roj ntawm cov nplaim ntawm cov raj honed thiab cov khoom siv chrome pas nrig.
3. Kev muab kua txob: Tshem tawm cov txheej oxide thiab lwm yam tsis huv ntawm cov hlau ntawm lub raj honed thiab chrome rods los ntawm pickling.
4. Kev ntxuav dej: cov raj honed lossis cov pas nrig hydraulic yog flushed nrog dej huv kom tshem tawm cov residues los ntawm cov txheej txheem pickling.
5. Kev qhib: Siv cov activator los kho cov hlau ntawm lub raj honed thiab piston pas nrig kom nce lawv cov adhesion rau chromium txheej.
6. Chrome plating: Cov khoom no raug muab tso rau hauv lub dab dej chromium plating thiab ib txheej chromium raug tso rau ntawm qhov chaw ntawm cov khoom los ntawm cov txheej txheem electrolytic. Cov txheej txheem no yuav tsum tau tswj cov dej ntws tam sim no, qhov kub thiab lub sijhawm kom ntseeg tau tias cov txheej chromium ntawm lub pas nrig chrome piston sib npaug thiab zoo.
7. Kev ua tiav nto: Tom qab lub pas nrig piston tau plated chromium, qhov khoom xav tau qee qhov kev ua tiav tom qab, xws li polishing, kev ntxhov siab annealing lossis sealing, kom txhim kho nws cov kev ua tau zoo. Cov pas nrig tau ua tiav hauv ob theem: tom qab sib tsoo thiab polishing. Lub txheej chrome raug txo kom txog qhov tuab xav tau ntawm txhua theem thiab polished kom tau txais qhov tiav zoo meej.
8. Kev Tshuaj Xyuas: Tshawb xyuas qhov tuab, qhov ntxhib, qhov sib xws thiab qhov nplaum ntawm cov txheej chromium plating ntawm cov pas nrig chrome kom paub tseeb tias nws ua tau raws li cov qauv zoo.
9. Ntim: Thaum kawg, lub raj honed thiab piston pas nrig tsim nyog tau ntim los tiv thaiv lawv cov nplaim los ntawm kev puas tsuaj thaum lub sijhawm thauj mus los thiab khaws cia.
Qhov zoo ntawm kev siv chrome plating
Qhov zoo ntawm kev hnav thiab kev tiv taus corrosion ntawm cov chromium nyuaj ua rau nws yog ib daim ntawv thov nrov rau cov thooj voos kheej kheej hydraulic, ntawm lwm yam txiaj ntsig.
Kev plating chrome tuaj yeem ua tau ntawm qhov kub qis yam tsis cuam tshuam rau cov hlau puag. Nws yog qhov tsim nyog rau cov qauv nyuaj thiab tsis sib xws, suav nrog cov qhov thiab cov tho qhov. Qhov kev nplaum zoo heev, uas txhais tau tias muaj kev pheej hmoo me ntsis ntawm kev tawg lossis tev tawm thaum siv.
