Nrog rau kev siv cov xim-coated steel nplooj ntawv nyob rau hauv kev tsim kho kev lag luam, tib neeg cov xim-coated steel nplooj ntawv tseem nce ntxiv.
Raws li kev txheeb cais tsis tiav: Hauv xyoo 2016, Tuam Tshoj txoj kev siv cov ntawv pleev xim ua ntej yog kwv yees li 5.8 lab tons.Yog li, yuav ua li cas raws nraim li cas cov xim hlau phaj ua ntej?
Xim-coated steel phaj(tseem hu ua organic coated steel daim hlau thiab pre-coated steel daim hlau) muaj npe tom qab lub hauv paus steel daim hlau (xa mus rau substrates) coated nrog ntau yam xim.
Xim-coated steel ntawv yog cov khoom lag luam nrog lub voj voog ntev ntev.Los ntawm kub dov mus rau txias dov, nws muaj ib tug tshwj xeeb thickness, dav thiab qauv, thiab ces undergoes annealing, galvanizing thiab xim txheej los tsim ib tug yeeb yuj.xim-coated ntawv.Cov txheej txheem tseem ceeb ntawm cov xim txheej txheej muaj xws li: txheej txheem Pretreatment, txheej txheej txheej, txheej txheej ci
1 、 Cov txheej txheem ua ntej
Nws yog tsuas yog cov txheej txheem ntawm kev tshem tawm impurities thiab roj txuas rau saum npoo tom qab lub substrate yog ntxuav;thiab tau txais kev sib xyaw oxidation thiab kev kho mob passivation los tsim cov yeeb yaj kiab ua ntej.Cov zaj duab xis pretreatment yog ib qho txiaj ntsig zoo los txhim kho lub zog sib txuas ntawm cov substrate thiab txheej.
2 、 Txheej txheej txheej
Tam sim no, txheej txheem txheej txheej feem ntau siv rau cov xim txheej hauv cov nroj tsuag steel loj yog cov menyuam txheej.Yob txheej yog coj cov xim nyob rau hauv lub lauj kaub xim rau lub txheej cov menyuam los ntawm ib tug siv cov menyuam, thiab ib tug tej thickness ntawm ntub zaj duab xis yog tsim nyob rau hauv lub txheej txheej., Thiab tom qab ntawd hloov cov txheej txheem ntub dej no mus rau txheej txheej txheej txheej ntawm substrate nto.Los ntawm kev kho cov menyuam sib txawv, siab thiab cov menyuam ceev, cov txheej tuab tuaj yeem nce lossis txo qis hauv qee qhov ntau; Nws tuaj yeem pleev xim rau ntawm ib sab lossis ntawm ob sab tib lub sijhawm.Txoj kev no yog ceev ceev thiab muaj ntau lawm efficiency.
3 、 Cov txheej txheem ci
Cov txheej txheem ci feem ntau cuam tshuam nrog kev kho cov txheej txheem ntawm cov hlau phaj, uas txhais tau hais tias cov txheej txheej tau dhau los ua cov tshuaj polycondensation, polyaddition, crosslinking thiab lwm yam kev cuam tshuam nyob rau hauv ib qho kub thiab lwm yam kev mob los ntawm lub ntsiab zaj duab xis-forming khoom, pab. film-forming material thiab curing agent.Cov txheej txheem ntawm kev hloov ntawm cov kua mus rau cov khoom siv.Cov txheej txheem kho thiab cov txheej txheem ci feem ntau suav nrog cov txheej txheem txheej txheej ci, nplua txheej ci thiab cov khoom siv khib nyiab sib xyaw.
4 、 Tom qab ua tiav ntawmpre-painted hlaudaim ntawv
Xws li embossing, luam ntawv, laminating thiab lwm txoj kev kho mob, waxing lossis tiv thaiv zaj duab xis kuj tuaj yeem ntxiv, uas tsis yog tsuas yog ua rau cov nyhuv anti-corrosion ntawm cov xim-coated phaj, tab sis kuj tiv thaiv cov xim-coated phaj los ntawm khawb thaum tuav lossis ua. .
