Kev ua hauj lwm ua ntej ntawm lub tshuab nqus tsev txheej feem ntau suav nrog cov kauj ruam hauv qab no, txhua tus ntawm cov uas xav tau lub luag haujlwm tshwj xeeb los xyuas kom meej qhov zoo thiab cov nyhuv ntawm txheej txheej txheej:
No.1 Cov kauj ruam kho ua ntej
1. Nto sib tsoo thiab polishing
Siv cov tshuaj abrasives thiab polishing cov neeg ua haujlwm los ua cov txheej txheem txheej txheem ntawm qhov chaw plated kom tshem tawm cov ntxhib microstructure ntawm qhov chaw thiab ua tiav qee qhov kev ua tiav.
Muaj nuj nqi: Txhim kho qhov adhesion thiab uniformity ntawm lub txheej, ua kom lub ntsej muag ntawm lub txheej smoother thiab zoo nkauj dua.
2.Degreasing
Txais cov kuab tshuaj dissolution, tshuaj los yog electrochemical txoj kev kom tshem tawm cov roj thiab roj nyob rau saum npoo ntawm plated qhov chaw.
Kev Ua Haujlwm: Tiv thaiv cov roj thiab roj los ntawm kev tsim cov npuas, flaking thiab lwm yam tsis xws luag hauv txheej txheej txheej txheej, thiab txhim kho qhov adhesion ntawm txheej.
3. Kev ntxuav
Siv cov kua qaub, alkali, cov kuab tshuaj thiab lwm yam tshuaj immersion los yog ultrasonic, plasma ntxuav ntawm plated qhov chaw kom tshem tawm cov oxides, xeb thiab lwm yam impurities.
Lub luag haujlwm: txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yuav tsum tau tshem tawm cov txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej
4. Kev kho mob ua kom muaj zog
Erode nto ntawm plated qhov chaw hauv cov kua qaub tsis muaj zog lossis cov tshuaj tshwj xeeb kom tshem tawm cov txheej txheem passivation ntawm qhov chaw thiab txhim kho cov haujlwm ntawm qhov chaw.
Lub luag haujlwm: los txhawb cov tshuaj tiv thaiv lossis kev sib xyaw ntawm lub cev ntawm cov khoom siv txheej thiab plated nto, txhawm rau txhim kho kev sib xyaw ua ke thiab ua haujlwm ntev ntawm cov txheej.
No.2 lub luag hauj lwm ntawm pretreatment
1. Txhim kho qhov zoo ntawm txheej
Kev kho ua ntej tuaj yeem ua kom ntseeg tau tias qhov chaw ntawm plated yog huv si, du thiab tsis muaj impurities, uas yog qhov tsim nyog rau cov khoom sib txawv ntawm cov khoom siv txheej txheej thiab sib xyaw ua ke.
Qhov no pab txhim kho cov txheej adhesion, uniformity thiab hardness thiab lwm yam kev ua tau zoo.
2. Txhim kho cov txheej txheem txheej txheej
Cov txheej txheem pretreatment tuaj yeem hloov kho raws li cov khoom siv ntawm cov khoom siv plated thiab cov txheej txheem txheej txheem kom haum rau cov txheej txheem txheej txheej thiab cov khoom siv sib txawv.
Qhov no yuav pab txhim kho cov txheej txheem txheej txheem txheej txheem thiab txhim kho cov khoom tsim tau thiab txheej txheej zoo.
3. Txo cov txheej txheem txheej txheem
Pretreatment tuaj yeem tshem tawm cov oxides, cov ntaub so ntswg xoob, burrs thiab lwm yam qauv ntawm qhov chaw plated, tiv thaiv cov qauv no los ntawm qhov tsis xws luag thaum txheej txheej txheej txheej.
Qhov no pab txo cov npuas, flaking, tawg thiab lwm yam tsis xws luag hauv txheej txheej txheej, thiab txhim kho qhov zoo nkauj thiab siv tau ntawm txheej.
4. Ua kom muaj kev ruaj ntseg ntau lawm
Cov kauj ruam ntawm cov roj degreasing thiab tshuaj ntxuav hauv cov txheej txheem pretreatment tuaj yeem tshem tawm cov khoom tawg thiab tawg thiab cov tshuaj lom thiab teeb meem ntawm qhov chaw plated.
Qhov no yuav pab txo qis kev pheej hmoo ntawm hluav taws kub, tawg lossis ib puag ncig muaj kuab paug thiab lwm yam kev nyab xeeb ntawm cov txheej txheem txheej.
Hauv cov ntsiab lus, kev ua haujlwm ua ntej ntawm lub tshuab nqus tsev muaj xws li kev sib tsoo thiab polishing, roj degreasing, tshuaj ntxuav thiab ua kom cov txheej txheem kho. Txhua yam ntawm cov kauj ruam no suav tias yog lub luag haujlwm tshwj xeeb los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm txheej txheej txheej txheej. Los ntawm pretreatment, txheej txheej zoo tuaj yeem txhim kho, txheej txheem txheej tuaj yeem ua kom zoo dua qub, cov txheej txheem txheej txheem tuaj yeem txo qis thiab kev ruaj ntseg ntau lawm tuaj yeem lav.
