1.Dab tsi yog qhov sib txawv tseem ceeb ntawm galvanized coils thiab xim -coated steel ntawv?
Galvanized steel kauj: Qhov tseem ceeb, nws yog cov khoom siv hauv paus. Nws yog tsim los ntawm plating ib txheej ntawm zinc rau saum npoo ntawm txias -rolled steel kauj, feem ntau muab kev tiv thaiv corrosion zoo heev. Nws tsis muaj xim (nyiaj -dawb) thiab ua cov khoom siv rau kev ua haujlwm tom ntej (xws li tha xim).
Xim-coated steel ntawv: Lub npe tag nrho yog "xim-coated steel ntawv," thiab nws yog ib qho tseem ceeb ntawm cov khoom tiav. Nws feem ntau siv galvanized steel coil ua cov khoom siv hauv paus, ua tiav cov txheej txheem pretreatments, thiab tom qab ntawd txuas ntxiv txheej txheej nrog ntau cov organic coatings (xws li polyester, silicone- hloov polyester, PVDF, thiab lwm yam), ua raws li kev ci thiab kho. Koj tuaj yeem nkag siab nws li: Xim -coated steel ntawv=Galvanized steel kauj + Kev tshaj lij txheej txheej txheej txheej.
2.Dab tsi yog qhov ua ntej- xim kho rau galvanized coils thiab xim hlau ntawv?
Kev kho ua ntej- yuav tsum tau kho ua ntej xim galvanized coils. Lawv yuav tsum tau ua kom nruj degreasing thiab tshuaj hloov pauv tshuaj (xws li phosphating thiab passivation) los tsim ib qho "txheej thauj tog rau nkoj" uas txhim kho qhov adhesion ntawm cov xim zaj duab xis.
Kev kho ua ntej- xim xim ntawm cov xim hlau tau ua tiav. Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim cov xim hlau los xij.
3.Dab tsi yog qhov txawv ntawm txoj kev xim ntawm galvanized coils thiab xim -coated steel ntawv?
Galvanized coils tuaj yeem coated los ntawm kev txau, cov menyuam txheej, thiab lwm yam, tab sis raws li cov khoom siv coil, cov txheej txheem txuas ntxiv yog qhov tsim nyog tshaj plaws.
Cov xim hlau phaj txais cov txheej txheem txuas ntxiv rau cov menyuam txheej txheej txheem ntau tshaj plaws, uas ua rau cov txheej txheem tsis sib xws thiab ua haujlwm siab heev.
4.Dab tsi yog qhov zoo ntawm cov xim ntawm galvanized coils thiab xim -coated steel ntawv?
Qhov zoo ntawm galvanized coils nyob ntawm theem ntawm kev ua, tab sis nws yog ib qho nyuaj rau ua tau zoo tib yam li ib tug tag nrho -scale xim -coated steel ntawv ntau lawm kab los ntawm tsuas colouring tus neeg, me me batch.
Xim- cov ntawv hlau coated yog cov zoo heev. Cov txheej thickness, xim, thiab gloss yog zoo ib yam, thiab cov xim zaj duab xis kev ua tau zoo (durability, khawb kuj) yog guaranteed.
5.Cov khoom siv twg yog qhov tsim nyog tshaj li txheej txheej rau xim?
Galvanized coil yog txheej txheej zoo heev rau xim.
Vim li cas? Zinc txheej muab kev tiv thaiv cathodic, ua raws li "sacrificial anode," rau cov ntawv hlau. Txawm tias muaj me ntsis khawb ntawm cov xim zaj duab xis, zinc nyiam corrodes, tiv thaiv cov hlau substrate los ntawm xeb. Qhov no nthuav dav lub neej tag nrho ntawm cov qauv.
Yog li ntawd, feem ntau siab - xim zoo- cov ntawv hlau coated xaiv galvanized coil ua lawv cov khoom siv hauv paus. Hauv lwm lo lus, xim -coated steel ntawv koj yuav yuav muaj ib txheej ntawm galvanized kauj hauv qab.
