Xim -coated steel ntawv yog ib hom hlau sib xyaw cov khoom siv dav hauv kev tsim kho. Lawv cov hauv paus ntsiab lus tseem ceeb yog xav txog plaub yam: txheej txheem xim txheej, cov qauv sib xyaw, kev tiv thaiv txheej, thiab hnav tsis tau siab - lub zog muaj zog.
Txheej Txheej Txheej Xim: Xim- cov ntawv hlau coated ua tiav cov haujlwm zoo nkauj thiab kev tiv thaiv los ntawm txheej txheej txheej organic rau saum npoo ntawm cov ntawv hlau. Cov txheej txheem muaj xws li pretreatment (tshem tawm impurities thiab oxides los txhim kho adhesion), primer txheej (muab ib qho yooj yim los tiv thaiv- txheej txheej), topcoat txheej (ua kom xim thiab gloss), thiab kho (kho cov txheej los ntawm siab - ci ci). Cov txheej txheem no tso cai rau ntau yam kev xaiv pom thaum tsim huab cua- tiv taus thiab corrosion- tiv thaiv txheej.
Composite Structure: Xim-coated steel ntawv feem ntau siv ntau- txheej txheej tsim. Cov qauv tsim yog cov ntawv hlau + cov khoom siv rwb thaiv tsev (xws li polystyrene, pob zeb ntaub plaub, thiab lwm yam) + steel ntawv. Cov qauv no tsis yog tsuas yog muab cov xim -coated steel ntawv zoo heev thermal rwb thaiv tsev kev ua tau zoo tab sis kuj zoo txo lub tsev siv zog. Piv txwv li, pob zeb wool sandwich panels ua tau zoo nyob rau hauv hluav taws kub tsis kam thiab thermal rwb thaiv tsev, ua rau lawv haum rau industrial cov nroj tsuag thiab pej xeem vaj tse nrog siab rwb thaiv tsev.
Kev Tiv Thaiv Txheej: Cov txheej txheem organic ntawm cov xim -coated steel ntawv muaj cov tshuaj tiv thaiv corrosion zoo heev, muab kev tiv thaiv ntev - tiv thaiv ib puag ncig kev yaig xws li hluav taws xob ultraviolet thiab kua qaub los nag. Cov txheej tseem tiv thaiv cov ntawv hlau los ntawm xeb thiab kev laus, ua kom nws lub neej ua haujlwm ntev. Qee cov khoom siv siab- kawg siv cov fluorocarbon txheej, nrog rau huab cua tsis kam tshaj 20 xyoo, haum rau huab cua huab cua.
Lub teeb yuag thiab siab -Lub zog: Xim- cov ntawv hlau coated yog ua los ntawm cov hlau nyias nyias (feem ntau yog 0.4-} 1.2mm tuab) ua ke nrog cov ntaub ntawv rwb thaiv tsev, ua rau qhov hnyav tsuas yog 1/30 txog 1/20 ntawm cov qauv cib-pob zeb. Cov yam ntxwv no pab txhawb kev thauj mus los thiab kev teeb tsa thaum tswj hwm lub zog muaj zog, muaj peev xwm tiv taus qhov hnyav ntawm 0.5-1.0kN / m², ua tau raws li cov kev xav tau ntawm ntau lub tsev.
