Cov teeb meem uas yuav tsum tau them sai sai rau hauv cov txheej txheem pretreatment ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj zoo ua qhov chaw

Cov teeb meem uas yuav tsum tau them sai sai rau hauv cov txheej txheem pretreatment ntawm finely machined qhov chaw: Txawm hais tias lub ntuj oxide zaj duab xis nyob rau saum npoo ntawm finely machined qhov chaw tsuas yog tsim thiab yooj yim tshem tawm, nws yog mos thiab hnyav, tshwj xeeb tshaj yog nyob rau hauv thiab ib ncig ntawm lub qhov ( Yog hais tias nws yog ncaj qha ntxuav nrog alkali, nws yuav tsis tsuas yog greasy thiab nyuaj rau tshem tawm, tab sis kuj lub finely machined nto tsis tuaj yeem tiv taus ntev. Lub sij hawm muaj zog alkali corrosion, uas tseem yuav cuam tshuam qhov roughness ntawm workpiece nto.

Cov teeb meem uas yuav tsum tau them nyiaj mloog mus rau hauv cov txheej txheem pretreatment ntawm casting qhov chaw: tsis yog txhua qhov chaw ntawm casting qhov chaw yog machined, thiab lub unmachined nto muaj ib tug ntau heev tuab oxide txheej tsim thaum lub sij hawm casting txheej txheem, thiab ib co kuj muaj cov xuab zeb txheej. Nyob rau hauv ib txwm muaj xwm txheej, machining los yog sandblasting txoj kev ua ntej tshem tawm cov thawj oxide zaj duab xis ntawm qhov no, los yog tom qab alkaline ntxuav, thiab ces txheej txheem, tsuas yog nyob rau hauv no txoj kev yuav tsis tsuas tshem tawm cov thawj oxide txheej ntawm lub unprocessed ib feem, tab sis kuj zam lub siab ntev. ntawm machined ib feem. Hloov qhov loj.

Nqus electroplating hluav taws xob cua sov tube nyuaj chrome txheej

Hard chrome plating yog txheej txheem ntau heev thiab hom hauv electroplating. Nws tsim cov txheej txheej tawv chrome rau ntawm qhov chaw ntawm cov khoom yuav tsum tau plated los ntawm electroplating, uas plays lub luag haujlwm thiab txhim kho qhov zoo ntawm cov tawv chrome plated qhov chaw. Yog li cia peb tshawb xyuas lwm yam ntawm nws hauv qab no. Txawm hais tias nws tau qhia ua ntej, nws tsis ntau, yog li nws yuav tsum tau mus tom ntej.
