Ntev npaum li cas rau corrosion tsis kam ntawm cov xim dc01 txias- rolled steel kawg?
Cov xeb ntawd ntawm cov xim dc01 txias- rolled steel tsim muaj nyob ntawm plaub tus txheej txheem tseem ceeb, txheej txheem thov, thiab txheej txheem ua haujlwm. Lub corrosion kuj yuav sib txawv los ntawm ntau dua 10 zaug nyob rau hauv cov xwm txheej sib txawv. Cov hauv qab no, raws li cov qauv kev lag luam ib txwm (xws li ISO 12944), piav qhia txog cov txheej txheem kev ua haujlwm tsis meej los ntawm "ib puag ncig + thiab qhia meej txog qhov tseem ceeb ntawm cov yam ntxwv:
1. Kev Ua Ntej ntawm Cov Ntsiab Lus cuam tshuam cuam tshuam txog kev ruaj khov
Ua ntej kev txiav txim siab kav, nws yog ib qho tsim nyog los ua ntej txiav txim siab qhov hnyav ntawm txhua qhov (los ntawm siab siab tshaj plaws):
Kev siv ib puag ncig (corrosion siv): Qhov no yog qhov tseem ceeb ntawm ib puag ncig "thiab thaj av qhuav ntawm 3-5 zaug;
Txheej txheem txheej (Primer + Topcoat ua ke / naj npawb ntawm cov tsho tshaj plaws {} Lub ntsiab lus tseem ceeb ntawm ib sab todcoat piv rau ib qho kev sib txawv ntawm 2-3 zaug;
Substrate Pretreatment Zoo: Qhov no yog qhov tseem ceeb hauv paus - txau yam tsis muaj kev tshem tawm thiab xeb txhawm rau txhawm rau txhawm rau hauv 1-2 xyoos. Sa2.5 qib sandblasting pretreatment tuaj yeem muab ob npaug rau lub durability;
Cov txheej txheem thov (zaj duab xis tuab / kho tuab / kho): Qhov no yog qhov tseem ceeb yog tsawg dua 80μm, lub neej pabcuam yuav raug luv los ntawm 15% ~ 20%.
