Xim coated board yog ib lub tsev ntsuab thiab ib puag ncig tus phooj ywg.Yuav ua li cas xaiv nws kom raug, siv nws tsim nyog, thiab txhim kho nws txoj kev pab cuam lub neej yog qhov teeb meem tseem ceeb tshaj plaws rau cov tswv thiab cov neeg tsim vaj tsev engineering.Baosteel, raws li ib tug tag nrho cov txheej txheem steel nroj tsuag, muaj kev nplua nuj nyob rau hauv ntau lawm thiab siv cov xim coated daim hlau."Kev Xaiv Cov Khoom Siv Tshawb Fawb" module muab cov lus qhia luv luv thiab kev qhia rau cov neeg siv ntawm kev xaiv thiab siv cov xim coated.
Kev xaiv kom raug ntawm cov xim coated panels yuav tsum xav txog tej yam ntuj tso ib puag ncig, kev siv ib puag ncig, tsim lub neej, thiab cov yam ntxwv ntawm lub tsev, thiaj li xaiv cov hlau hom, specification, txheej, thiab txheej uas phim nws.Architects, engineering tswv, thiab processors xav txog kev nyab xeeb kev ua tau zoo (kev cuam tshuam tsis kam, seismic tsis kam, hluav taws tsis kam, cua siab tsis kam, snow resistance), nyob rau hauv kev ua tau zoo (waterproof, suab rwb thaiv tsev, rwb thaiv tsev), durability (kev ua qias tuaj, durability, zoo li qub) , thiab kev lag luam (tus nqi qis, kev ua haujlwm yooj yim, kev saib xyuas yooj yim, thiab hloov tau yooj yim) ntawm cov tsev.Rau cov neeg muag khoom ntawm cov xim coated steel daim hlau, cov khoom no yuav tsum tau hloov mus rau hauv cov xim coated steel phaj cov khoom los ntawm steel mills thiab lav.Kev ua tau zoo ntawm cov xim coated steel daim hlau feem ntau suav nrog cov khoom siv hluav taws xob (lub zog tensile, yield zog, elongation), txheej txheej (txheej hom, txheej thickness, thiab txheej adhesion), thiab txheej kev ua tau zoo (txheej hom, xim, gloss. , durability, processability, thiab lwm yam).Ntawm lawv, cua tsis kam, cuam tshuam tsis kam, daus tiv thaiv, av qeeg, thiab lwm yam yog txhua yam cuam tshuam nrog cov khoom siv hluav taws xob, thiab tau kawg, lawv kuj muaj feem xyuam rau lub waveform, thickness, ncua, thiab qhov sib txawv ntawm cov xim profiled steel phaj. .Yog tias tsim nyog cov xim coated steel daim hlau raug xaiv thiab ua ke nrog tsim nyog profiled steel phaj tsim, nws tuaj yeem tsis tsuas yog ua tau raws li kev nyab xeeb ntawm cov tsev tab sis kuj txo cov nqi engineering.Lub durability, kev ua tau zoo, thiab zoo li khaws cia ntawm cov ntaub ntawv yog feem ntau txiav txim siab los ntawm durability ntawm coatings thiab coatings.

Txheej ntau yam

Tam sim no, hom coatings siv rau xim coated steel daim hlau muaj xws li polyester txheej (PE), fluorocarbon txheej (PVDF), silicon hloov txheej (SMP), siab huab cua tiv thaiv txheej (HDP), acrylic acid txheej, polyurethane txheej (PU) , yas sol txheej (PVC), thiab lwm yam.

Ordinary polyester (PE, Polyester)
PE txheej tau zoo adhesion rau cov ntaub ntawv, thiab xim coated steel phaj yog ib qho yooj yim rau txheej txheem thiab tsim, nqi-zoo, thiab muaj ntau yam khoom.Muaj ntau yam kev xaiv rau xim thiab gloss.Nyob rau hauv kev raug ncaj qha rau ib puag ncig, nws lub neej tiv thaiv corrosion tuaj yeem ncav cuag li 7-8 xyoo.Txawm li cas los xij, nyob rau hauv ib puag ncig kev lag luam lossis thaj chaw muaj kuab paug hnyav, nws lub neej kev pabcuam yuav raug txo qis.Txawm li cas los xij, polyester coatings tsis zoo rau UV tiv thaiv thiab zaj duab xis hmoov tsis kam.Yog li ntawd, kev siv cov PE coatings tseem yuav tsum tau txwv, thiab lawv feem ntau yog siv nyob rau hauv cov cheeb tsam uas tsis tshua muaj pa phem los yog cov khoom uas yuav tsum tau ntau molding thiab ua.

Silicone Hloov Polyester (SMP)
Vim muaj cov pab pawg reactive - OH / - COOH nyob rau hauv polyester, nws yog ib qho yooj yim rau react nrog lwm yam polymers thiab tshuaj.Txhawm rau txhim kho lub hnub ci tiv thaiv thiab pulverization ntawm PE, silicone resin nrog cov xim zoo nkauj thiab kub tsis kam yog siv rau cov tshuaj tiv thaiv denaturation.Qhov sib piv denaturation nrog PE tuaj yeem nyob nruab nrab ntawm 5% thiab 50%.SMP muab kev ua haujlwm zoo dua rau cov hlau phaj, nrog rau lub neej corrosion mus txog 10-12 xyoo.Tau kawg, nws cov nqi kuj tseem siab dua li ntawm PE, Txawm li cas los xij, vim qhov tsis txaus ntseeg adhesion thiab kev ua haujlwm ntawm Silicone resin rau cov ntaub ntawv, SMP xim coated steel daim hlau tsis haum rau cov xwm txheej uas yuav tsum tau ua ntau yam txheej txheem molding, thiab feem ntau yog siv rau. tsim lub ru tsev thiab sab nrauv phab ntsa.

Huab cua resistant polyester (HDP, High ruaj polyester)
Hais txog qhov tsis txaus ntawm PE thiab SMP, British tuam txhab HYDRA (tam sim no tau los ntawm BASF) thiab Swedish lub tuam txhab BECKER tsim HDP polyester txheej thaum ntxov 2000 uas tuaj yeem ua tiav 60-80% huab cua tsis kam rau PVDF txheej, thiab zoo dua rau cov txheej txheem silicon hloov polyester txheej. .Lawv cov huab cua tiv thaiv sab nraum zoov mus txog 15 xyoo.Cov huab cua resistant polyester resin yog tsim los siv monomers uas muaj cov qauv cyclohexane kom ua tiav qhov sib npaug ntawm qhov yooj yim, huab cua tsis kam, thiab nqi.Aromatic dawb polyols thiab acids yog siv los txo qhov nqus ntawm UV teeb los ntawm cov resin, ua tiav cov huab cua tsis kam ntawm txheej.Qhov sib ntxiv ntawm ultraviolet absorbers thiab steric hindrance amines (HALS) nyob rau hauv cov txheej txheem txheej txheem txhim kho huab cua tsis kam ntawm cov xim zaj duab xis.Huab cua tiv taus polyester coil txheej tau lees paub los ntawm kev ua lag luam txawv teb chaws, thiab nws cov nqi ua tau zoo yog qhov zoo heev.
PVC Plastisol
PVC resin muaj cov dej tsis zoo thiab cov tshuaj tiv thaiv, thiab feem ntau yog coated nrog cov ntsiab lus siab, nrog cov txheej tuab ntawm 100-300 μ Ntawm m, nws tuaj yeem muab cov txheej txheem PVC du lossis lub teeb embossing kho raws li embossing txheej;Vim qhov tseeb tias PVC txheej yog cov thermoplastic resin nrog cov yeeb yaj kiab siab, nws tuaj yeem muab kev tiv thaiv zoo rau cov ntawv hlau.Tab sis PVC tsis muaj zog tiv thaiv tshav kub.Thaum ntxov, nws tau siv dav hauv Tebchaws Europe, tab sis vim nws cov khoom tsis zoo ib puag ncig, tam sim no tau siv tsawg thiab tsawg.

PVDF Fluorocarbon yog tsim los ntawm PVDF
Vim yog lub zog sib txuas ntawm cov tshuaj sib txuas ntawm PVDF, txheej txheej muaj kev tiv thaiv zoo heev thiab cov xim tuav.Nws yog cov khoom siv siab tshaj plaws hauv kev tsim kho kev lag luam cov xim coated steel phaj txheej, nrog rau qhov hnyav molecular thiab cov qauv ncaj nraim.Yog li ntawd, ntxiv rau cov tshuaj tiv thaiv, cov khoom siv kho tshuab, UV tsis kam, thiab kub ua haujlwm kuj tseem ceeb

Rau kev xaiv ntawm primer, muaj ob yam tseem ceeb tshaj plaws.Ib qho yog xav txog qhov adhesion ntawm primer thiab topcoat, nrog rau cov substrate.Lwm qhov yog tias cov primer muab feem ntau ntawm kev tiv thaiv corrosion ntawm txheej.Los ntawm qhov kev xav no, epoxy resin yog qhov kev xaiv zoo tshaj plaws.Yog tias xav txog kev hloov pauv thiab UV tsis kam, polyurethane primer kuj tuaj yeem xaiv.
Rau cov txheej txheej sab nraub qaum, qhov kev xaiv zoo tshaj plaws yog xaiv ob txheej txheej txheej, uas yog ib txheej ntawm sab nraub qaum thiab ib txheej ntawm sab nraub qaum, yog tias cov xim coated steel phaj yog nyob rau hauv ib lub board xeev.Cov primer thiab pem hauv ntej yog tib yam, thiab lub tsho sab saum toj yuav tsum yog lub teeb xim (xws li dawb) polyester.Yog hais tias cov xim coated steel phaj yog nyob rau hauv ib tug composite los yog sandwich lub xeev, nws yog txaus los thov ib txheej ntawm epoxy resin nrog zoo adhesion thiab corrosion kuj nyob rau tom qab.
Tam sim no, muaj ntau yam xim coated steel daim hlau, xws li tshuaj tua kab mob colour txheej, anti-static xim txheej, thermal rwb thaiv tsev xim txheej, nws tus kheej-tu xim txheej, thiab lwm yam. cov neeg siv, tab sis qee zaum nws tsis tuaj yeem sib npaug ntawm lwm yam kev ua haujlwm ntawm cov khoom siv xim coated.Yog li ntawd, thaum cov neeg siv xaiv cov xim xim coated steel phaj, lawv yuav tsum paub meej txog lawv cov kev xav tau tiag tiag.
