Theem tiv thaiv Corrosion tau DC01 txias-}} rolled steel ua tiav tom qab tha xim?
Lub Corrosion tiv thaiv kev ua tau zoo tshaj plaws DC01 txias - rolled steel tsis muaj qib tsau, qib. Hloov chaw, nws nyob ntawm plaub tus qauv tseem ceeb: Txheej Txheej Tsim, substrate pretreatment zoo, txheej txheem thov, thiab kev ua haujlwm. Nyob rau hauv cov kev mob sib txawv, theem kev tiv thaiv Corrosion muaj ntau los ntawm "Kev Tiv Thaiv Sab Hauv Tsev" nruab nrab}}}} qib theem tawm tsam tiv thaiv. " Cov ntsiab lus hauv qab no no siv cov qauv kev lag luam ib txwm (xws li ISO 12944):
1. Qhov tseem ceeb yam cuam tshuam rau theem kev tiv thaiv corrosion
Ua ntej kev txiav txim siab ib qib tshwj xeeb, nws yog ib qho tseem ceeb uas yuav tsum tau nkag siab thawj zaug ntawm plaub qhov tseem ceeb hauv qab no, uas ncaj qha txiav txim siab qhov kawg ntawm kev tiv thaiv corrosion:
Txheej Txheej (Primer + Topcoat Ua Haujlwm thiab Cov Cim Loj)
Ib qho txheej txheem (piv txwv li, tsuas yog ib lub sab topcoat): muaj cov kev tiv thaiv corrosion thiab yog qhov haum rau cov chaw ib puag ncig.
Sib txuas txheej (Primer + Topcoat, lossis Primer + Pyscoat + Topcoat tiv thaiv Corrosion thiab yog cov kev lag luam kev lag luam zoo. Hom, ua tau zoo siv: Epoxy Primer (Kev Ua Kom Zoo Tshaj Plaws)
Substrate pretreatment zoo
DC01 cold {- rolled steel nto yog nquag mus rau cov roj thiab cov nplai. Yog tias pretreatment tsis tiav, txheej txheej tuaj yeem yooj yim tev thiab npuas, ncaj qha txo cov corrosion tsis kam.
Tsim Nyog Pretreatment: Lub Substrate Nto yuav tsum tau dhau ib txheej txheem ntawm "Debreet tshem tawm, tsis muaj xeb, xeb) →
Tsis zoo pretreatment (yooj yim so): Txawm tias cov duab tha xim tuaj yeem txo qis cov xeb tsis kam. Cov txheej txheem thov (zaj duab xis tuab, kom qhuav thiab kho)
Txheej Txheej Diamond Thickness: Qhov no yog qhov tseem ceeb tshaj, feem ntau yuav tsum muaj plaub hau ntau dua los yog sib luag rau 100μm (ntau dua lossis sib npaug ntawm 120μm rau kev siv sab nraum zoov). Cov ntawv qhia tuab tsis txaus yuav ua rau muaj kev tawm tswv yim hauv cov xov xwm.
Kom qhuav thiab kho kom qhuav: cov txheej yuav tsum tau kho los ntawm saum npoo kom qhuav raws li cov yuav tsum tau ua kom qhuav (piv txwv, siab- kub raking). Incompletely cleats yog nquag mus tawg thiab ua tsis tiav.
Siv ib puag ncig (corrosion loj)
Qhov ntau corrosive ib puag ncig, qhov siab dua qhov yuav tsum tau ua rau txheej txheem txheej, thiab kev sib raug corrosion resistance qib yuav tsum tau sib xws:
Me corrosion: sab hauv tsev qhuav (piv txwv, cov cuab yeej chaw ua haujlwm vaj tse);
Mob nruab nrab: Nyob sab hauv tsev noo noo / maj mam oily page ib puag ncig (xws li, cov txheej txheem rhiav); Sab nraum zoov Rural huab cua;
Kev Nyab Xeeb Kev Mob: Thaj chaw sab nraum zoov (piv txwv li lub Hoobkas nyob ib puag ncig), ib puag ncig ntawm cov neeg ua ntsev, thiab siab} cov av noo kev cob qhia (piv txwv li, ua zaub mov). Ii. Cov kev tiv thaiv kev tiv thaiv qib ib txwm siv (raws li ISO 12944)
ISO 12944 yog lub hauv ntiaj teb lees paub cov qauv txheej txheem rau cov steel, kuj tseem siv tau los pleev xim DC01 txias- rolled steel. Nws cov ntsiab cai tseem ceeb yog kom phim cov txheej txheem txheej txheem rau kev tiv thaiv kev tiv thaiv ib puag ncig thiab qhia txog qhov kev tiv thaiv ua ntej txheej ua tsis tau):
