Acid p ickling thiab phosphating yog ib kauj ruam tseem ceeb hauv khib pretreatment, uas muaj kev cuam tshuam zoo rau qhov zoo thiab lub neej ntawm khib s.
Pickling thiab phosphating yog ib txoj hauv kev nyuab heev thiab muaj zog, thiab kev kho mob ua ntej ntawm qee cov zeeg loj loj yog hnub tag nrho ntawm cov quav thiab phosphating. Tam sim no, vim yog tus nqi, vim yog kev tiv thaiv ib puag ncig, ntau cov chaw tsis muaj kev tawm ntawm cov kauj ruam ntawm cov khoom qab zib thiab phosphating.
Thawj kauj ruam yog degreasing. Degreasing yog ua kom muaj kev kub siab rau alkali, uas yog ntxuav cov roj tua tawm ntawm cov txheej txheem hlau ua haujlwm. Cov kauj ruam no tau faib ua cov kauj ruam me me, ib qho yog ua ntej, qhov dej yog qhov tseem ceeb heev, txhua qhov yuav tsum tau ntxuav tom qab.
Cov kauj ruam thib ob yog xeb, xeb yog siv cov kua qaub (hydrochloric acid) immersion, yog li, kom tshem tawm xeb ntawm lub phom ntawm cov hlau ua haujlwm nrog cov kua qaub, feem ntau yog cov hlau phaj tshiab yuav ua tau, yog tias cov khoom raug muab tso rau lub sij hawm ntawm lub sij hawm, ntau xeb, nws yuav tsum tau xeb ntau zaus. Tom qab xeb tas, ntxuav nws.
Qhov thib peb kauj ruam yog qhov sib txawv ntawm qhov kev hloov, uas yog hu ua qhov sib txawv ntawm qhov sib txawv, yog siv cov alkali tsis muaj zog los sis tsis muaj zog alkali kom tsis txhob muaj cov kua qaub thiab alkali ntawm cov txheej txheem ua haujlwm, vim tias cov hlau ua haujlwm ntawm acid thiab alkali yog teeb meem rau kev txau. Yog li ntawd, cov kua qaub thiab lub hauv paus yuav tsum tau ua kom tsis muaj nuj nqis, yog li ntawd qhov chaw ua haujlwm ntawm cov hlau-daim hlau thiab lub cev tsis ua pa (ntsuas tus nqi paab), qhov txheej txheem no qee zaum tsis yog ib zaug ua haujlwm nrog, tom qab ua tiav ntawm lub ntsuas .
Plaub kauj ruam yog phosphating, phosphating kuj hu ua zinc phosphating, lub hom phiaj yog tshwm rau ntawm qhov hlau ntawm lub phomphating cov hlau, qhov yeeb yaj kiab no zoo heev, nrog rau zaj dab neeg no, tuaj yeem tiv thaiv cov cua thiab cua, tiv thaiv oxidation xeb, tab sis kuj zoo dua ua raws li cov yas hmoov txau ntau lawm kab tom qab.
Kauj ruam thib tsib yog qhov sau txog. Passivation yog cov kauj ruam kawg hauv acid pickling thiab phosphating. Lub hom phiaj yog tshem tawm ntau cov hmoov uas koom rau ntawm qhov phosphating zaj duab xis tom qab phosphating.
Cov kauj ruam thib rau yog ziab, qhov no yog qhov kawg ntawm cov tshuaj tua kua qaub thiab phosphating ua haujlwm, yog kev ntxuav cov ntxhua ua haujlwm nrog lub tshuab ziab khaub ncaws kom qhuav, tshem tawm cov hlau ua haujlwm ntawm cov cua ntswg.
Lub sijhawm ua haujlwm rau txhua kauj ruam no yog 40 feeb, nrog rau kev ntxuav, yog tias koj suav tag nrho cov kauj ruam thiab dhau los ntawm lawv ib zaug, koj yuav tsis tuaj yeem ua kom tiav rau hauv ib hnub. Thiab cov txheej txheem xav tau ntau yam tshuaj cov tshuaj, thiab cov peev ntau dua yog cov kev pab tiv thaiv ib puag ncig ntawm kev tiv thaiv ib puag ncig loj heev.
Yog li, tam sim no, ntau cov manufacturers hais tias lawv yog pickling phosphating, tab sis tus nqi yog tsawg heev, uas yog qhov teeb meem yeej, tsis yog kev dag cuav tsis tau nqa tawm pickling phosphating nyob rau hauv tag nrho, los yog cov khoom ua tiav jerry tsev. Nws feem ntau ntseeg hais tias tus nqi ntawm cov tshuaj pleev xim thiab phosphating yog li 1 yuan ntawm ib kilogram (kua tshuaj, qhov chaw, haujlwm, kev tiv thaiv ib puag ncig, thiab lwm yam).
Qhov txawv ntawm pickling phosphating thiab phosphating cov hlua uas tsis yog pickling yog tias cov racks uas tsis tau muab tua tau tawm ntawm lub hoobkas li lawv, tab sis vim tias tsis muaj degreasing, xeb tawm, phosphating, etc. Tus nplaim ntawm cov hlau workpiece tseem yog txau nrog rau tej yam no, huag, qhov zoo nkaus li zoo heev (qhov tseeb, qhov saum npoo thiaj paub qhov txawv, tsis muaj qhov ua kom tsis muaj qhov sib txawv tsis zoo, ntau npuas, me me thiab lwm yam), yuav siv tau rau ib lub sijhawm yog ib qho teeb meem, yog qhov chaw nyob yog cov dej qis heev, cov xim muaj peev xwm pib tawg rau ib nrab xyoo, xeb, Ntau tshaj li ib xyoos, cov racks tau xeb tag. Txawm hais tias lub chaw qhuav, qhov kev pab cuam lub neej yuav tsawg tshaj li ib nrab ntawm cov khib lub neej. Kuv pom ib tug khib peb tau 12 xyoo dhau los, tus neeg txias txias chaw, poob nthav tsis muaj cuab kev xeb, qhov no yog qhov credit ntawm kev ua ntej, yog tsis pretreated, khib lub neej mus txog rau ib thiab ib nrab xyoo.
Jracking yog tshwj xeeb hauv kev tsim pallet khib lav, khib nyiab khib, hluav taws xob hluav taws xob hluav taws xob, mezzanine thiab platform, shuttle tsheb tsis siv neeg cia, thawb rov qab khib, longspan khib, rivet khib, tsav hauv khib, thawv nquag khib, stacking khib thiab lwm yam ntsig txog kev cia khoom.
