Dab tsi yog pre-coated steel ntawv?
Hlau yog ib qho ntawm cov khoom siv ntau yam siv hauv kev lag luam thoob ntiaj teb vim nws lub zog, durability, thiab nqi-zoo. Txawm li cas los xij, cov hlau kuj tseem raug rau corrosion, uas tuaj yeem ua rau nws lub neej luv thiab txo nws cov txiaj ntsig hauv ntau yam kev siv. Txhawm rau tiv thaiv qhov teeb meem no, cov tuam ntxhab tau tsim cov txheej txheem hu ua pre txheej, uas suav nrog kev siv cov txheej txheem tiv thaiv rau cov hlau nto ua ntej nws tsim los rau hauv cov nplooj ntawv. Qhov tshwm sim yog ua ntej coated steel ntawv, ib yam khoom nrog txhim kho corrosion kuj thiab txhim kho zoo nkauj. Nyob rau hauv tsab xov xwm no, peb yuav delve tob rau hauv lub tswvyim ntawm pre coated steel ntawv, nws cov txheej txheem tsim, hom, daim ntawv thov, thiab zoo.
Taw qhia rau precoated steel ntawv
Precoated steel ntawv, tseem hu ua prepainted steel ntawv, yog cov khoom siv hlau coated dav siv hauv kev tsim kho, tsheb, thiab khoom siv hauv kev lag luam. Nws pib nrog lub hauv paus substrate ntawm txias-kuav los tiag steel los yog galvanized steel, mus rau ib tug tiv thaiv txheej yog thov. Cov txheej no tuaj yeem yog xim xim, xim hlau txheej, lossis ob qho tib si ua ke. Cov txheej txheem ua ntej txheej ua kom ntseeg tau tias cov ntawv hlau muaj kev tiv thaiv corrosion zoo dua, zoo heev nto tiav, thiab txhim kho kev zoo nkauj, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv.
Cov txheej txheem tsim khoom
Kev tsim cov txheej txheem ua ntej coated steel ntawv muaj ob peb kauj ruam uas ua kom cov khoom zoo thiab zoo ib yam. Cia peb ua tib zoo saib ntawm txhua theem:
1. Kev Tu: Lub hauv paus substrate, txawm tias nws yog txias-kuav los tiag steel los yog galvanized steel, ua raws li cov txheej txheem tu kom huv si kom tshem tawm tej yam kab mob, xws li av, roj, los yog xeb. Cov kauj ruam no yog ib qho tseem ceeb los xyuas kom meej adhesion ntawm txheej rau steel nto.
2. Kev kho deg: Tom qab cov txheej txheem ntxuav, cov ntawv hlau raug kho nrog cov tshuaj lossis cov khoom siv kho tshuab los txhim kho nws cov khoom nto. Qhov kev kho mob no ua kom yooj yim dua adhesion ntawm txheej thiab steel substrate.
3. Daim ntawv thov primer: Ib qho primer, feem ntau yog ua ke ntawm cov resins thiab pigments, yog siv rau cov ntawv hlau los txhawb adhesion, tiv thaiv corrosion, thiab txhim khu lub durability ntawm cov khoom kawg. Lub primer ua raws li cov txheej txheem tiv thaiv ntawm cov hlau substrate thiab topcoat.
4. Pre txheej daim ntawv thov: Nyob ntawm cov yam ntxwv xav tau thiab daim ntawv thov ntawm cov ntawv ua ntej coated steel, ntau yam txheej txheej tuaj yeem siv tau.
