CHROMING
Chrome plating, feem ntau hu ua chromium plating lossis nyuaj chrome, yog txheej txheem rau electroplating nyias txheej ntawm chromium ntawm cov khoom hlau. Cov txheej txheem chromium plating ntawm honed hlab thiab chrome rods yog txheej txheem kho saum npoo tsim los txhim kho cov hnav tsis kam, corrosion kuj thiab zoo nkauj ntawm cov khoom no. Chrome plating muab ib tug nto nrog siab hardness thiab tsawg coefficient ntawm kev sib txhuam, uas yog tshwj xeeb tshaj yog ib qho tseem ceeb rau dynamic seals nyob rau hauv hydraulic systems. Cov hauv qab no yog cov kauj ruam dav dav ntawm cov txheej txheem chromium plating rau honed hlab thiab piston rods:

1. Ntxuav:Ua ntej, lub honed raj thiab chrome pas nrig yuav tsum tau muab ntxuav kom huv si kom tshem tawm tag nrho cov roj, xeb, thiab impurities, thiab lawv qhov kawg yuav tsum tau them.
2. Degreasing:Siv cov tshuaj los yog kev siv tshuab los tshem tawm cov roj los ntawm qhov chaw ntawm cov hlab honed thiab chrome pas nrig.
3. Pickling:Tshem tawm cov oxide txheej thiab lwm yam impurities los ntawm cov hlau nto ntawm lub honed raj thiab chrome rods los ntawm pickling.
4. Flushing:honed hlab los yog hydraulic lub tog raj kheej rods yog flushed nrog dej huv kom tshem tawm cov seem ntawm cov txheej txheem pickling.
5. Kev ua haujlwm:Siv activator los kho cov hlau nto ntawm lub honed raj thiab piston pas nrig kom lawv adhesion mus rau chromium txheej.
6. Chrome plating:Cov khoom yog muab tso rau hauv chromium plating da dej thiab ib txheej ntawm chromium tso rau ntawm qhov chaw ntawm cov khoom siv los ntawm cov txheej txheem electrolytic. Cov txheej txheem no yuav tsum tau tswj qhov ceev tam sim no, kub thiab lub sijhawm kom ntseeg tau tias qhov sib xws thiab zoo ntawm cov chromium txheej ntawm chrome piston pas nrig.
7. Nto xov:Tom qab tus pas nrig piston yog chromium plated, ib feem xav tau qee qhov kev ua haujlwm tom qab, xws li polishing, kev ntxhov siab annealing lossis sealing, txhawm rau txhim kho nws cov kev ua tau zoo. Cov pas nrig yog ua tiav hauv ob theem: tom qab sib tsoo thiab polishing. Lub chrome txheej yog txo mus rau qhov yuav tsum tau thickness ntawm txhua theem thiab polished kom tau ib tug zoo meej nto tiav.
8. Kev tshuaj xyuas:Tshawb xyuas lub thickness, roughness, uniformity thiab adhesion ntawm chromium plating txheej ntawm chrome pas nrig kom paub tseeb tias nws ua tau raws li cov qauv zoo.
9. Ntim:Thaum kawg, qhov tsim nyog honed raj thiab piston pas nrig tau ntim los tiv thaiv lawv qhov chaw los ntawm kev puas tsuaj thaum thauj thiab khaws cia.
Qhov zoo ntawm chrome plating
Cov kev coj ua thiab kev tiv thaiv corrosion-resistant zoo ntawm hard chromium ua rau nws yog ib daim ntawv thov nrov rau hydraulic thooj voos kheej kheej, ntawm lwm cov txiaj ntsig.
Chrome plating tuaj yeem ua tau ntawm qhov kub thiab txias yam tsis muaj kev cuam tshuam rau lub hauv paus hlau. Nws yog tsim rau complex thiab tsis xwm yeem geometry, nrog rau qhov thiab tho txawv. Lub adhesion yog qhov zoo heev, uas txhais tau hais tias tsis tshua muaj kev pheej hmoo ntawm delamination lossis tev tawm thaum siv.
