Cov txheej txheem ua ntej kev kho mob yooj yim thiab tsis siv neeg ua ntej kev kho mob, tom kawg tau muab faib ua cov tshuaj tsuag tsis siv neeg thiab tsis siv tshuaj tsuag ob txheej txheem.Lub workpiece yuav tsum tau kho saum npoo kom tshem tawm cov roj thiab xeb ua ntej txau.Hauv seem no siv ntau cov kua, feem ntau yog xeb tshem tawm, degreasing tus neeg saib xyuas, hloov lub rooj, phosphating tus neeg saib xyuas thiab lwm yam.
Nyob rau hauv cov txheej txheem los yog rhiav ua ntej lub painting ntau lawm kab, yuav tsum tau them nyiaj mloog mus rau lub tsim ntawm tsim nyog yuav khoom, tsheb thauj mus los, cia thiab siv lub zog acid thiab alkali system, muab cov neeg ua hauj lwm nrog cov tsim nyog khaub ncaws tiv thaiv, hnav khaub ncaws zoo thiab txhim khu kev qha, tuav, teeb tsa cov khoom siv, nrog rau kev txhim kho kev kho mob thaum muaj xwm txheej ceev thiab kev cawm dim thaum muaj xwm txheej.Qhov thib ob, nyob rau hauv pretreatment seem ntawm painting ntau lawm kab, vim muaj ib tug tej yam nqi ntawm cov khib nyiab roj, khib nyiab kua thiab lwm yam peb pov tseg tshuaj, yog li ntawd nyob rau hauv cov nqe lus ntawm kev tiv thaiv ib puag ncig, nws yog tsim nyog los configure cua tso pa tawm, kua paug thiab. peb cov khoom siv pov tseg.
Qhov zoo ntawm pre-kho workpiece yuav tsum sib txawv vim qhov sib txawv pretreatment tov thiab txheej txheej ntau lawm kab.Kev ua haujlwm zoo dua ntawm cov khoom ua haujlwm, cov roj saum npoo av, xeb ua, txhawm rau tiv thaiv lub sijhawm luv luv kom xeb dua, feem ntau yuav tsum nyob rau hauv pretreatment tom qab ob peb txheej txheem, phosphating los yog passivation kev kho mob: ua ntej tshuaj tsuag hmoov, kuj yuav tsum muaj phosphating workpiece. rau ziab, rau nws qhov chaw noo noo.Me me batch ib zaug ntau lawm, feem ntau yog siv cov huab cua kom qhuav, tshav ntuj kom qhuav, cua kom qhuav.Thiab rau qhov ntau ntawm cov dej ntws ua haujlwm, feem ntau siv qhov ziab kom qhuav, siv qhov cub lossis ziab txoj kev.
Txau hmoov txheej koom haum tsim khoom
Rau cov khoom me me, cov khoom siv plua plav plua plav feem ntau yog siv, thiab rau cov khoom loj loj, phau ntawv lossis cov khoom siv plua plav tsis siv neeg feem ntau yog siv.Txawm hais tias phau ntawv los yog tsis siv neeg plua plav, kev tswj kom zoo yog qhov tseem ceeb heev.Txhawm rau kom ntseeg tau tias cov tshuaj txau cov hmoov ua haujlwm zoo sib xws, cov tuab tuab, txhawm rau tiv thaiv cov tshuaj tsuag nyias, cov tshuaj txau, so tawm thiab lwm yam tsis xws luag.
Txheej txheej ntau lawm hauv cov txheej txheem, tab sis kuj yuav tsum tau them sai sai rau qhov sib txuas ntawm qhov chaw ua haujlwm, ua ntej nkag mus rau hauv kev kho, yuav tsum ua raws li nws cov hmoov kom deb li deb tau yuav tshuab tawm, tiv thaiv cov hmoov ntau dhau ntawm tus nuv, qee qhov rau kev kho kom tshem tawm cov hmoov seem. ua ntej muaj teeb meem, yuav tsum tau raws sij hawm stripping nuv muaj solidified hmoov zaj duab xis, conductive los xyuas kom meej tus nuv yog zoo, thiab tus naj npawb ntawm artifacts rau cov hmoov.
Kev tswj ntau lawm ntawm cov txheej txheem curing hauv txheej txheej
Cov txheej txheem no yuav tsum tau them sai sai rau: txau cov khoom ua haujlwm, yog tias nws yog ib pawg me me ntawm ib qho kev tsim khoom, mus rau hauv lub qhov cub ua ntej yuav tsum tau saib xyuas kom tsis txhob ntog hmoov, xws li cov hmoov txhuam cov phenomenon, yuav tsum tau raws sij hawm tshuaj tsuag hmoov.Thaum ci, txheej txheem nruj thiab kub, tswj lub sijhawm, ua tib zoo saib xyuas kom tsis txhob muaj xim sib txawv, dhau sijhawm ci los yog luv luv los ntawm kev kho tsis txaus.
Rau cov khoom loj ntawm cov khoom siv tsis siv neeg, nyob rau hauv txoj kev ziab ua ntej kuj ua tib zoo xyuas seb cov tshuaj xau, tshuaj tsuag nyias lossis cov hmoov av hauv zos, xws li pom qhov tsis tsim nyog, yuav tsum raug kaw kom tsis txhob nkag mus rau hauv txoj kev ziab, kom deb li deb tau. tshem tawm cov tshuaj tsuag.Yog tias ib tus neeg ua haujlwm tsis tsim nyog vim yog cov tshuaj tsuag nyias, nws tuaj yeem rov ua dua thiab rov ua kom khov dua tom qab kho.
