Sab hauv thiab sab nrauv yas-coated steel kav yog tsim los ntawm melting ib txheej ntawm polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) hmoov, thiab tsis muaj tshuaj lom polycarbonate nrog lub thickness ntawm 0.5 mus rau 1.0mm. nyob rau sab hauv phab ntsa ntawm cov yeeb nkab steel.Cov yeeb nkab steel-yas composite tsim los ntawm cov khoom siv organic xws li propylene (PP) lossis tsis muaj tshuaj lom polyvinyl chloride (PVC) tsis tsuas yog muaj qhov zoo ntawm lub zog siab, kev sib txuas yooj yim, thiab tsis kam mus rau dej ntws, tab sis kuj overcomes lub corrosion ntawm hlau. cov kav dej thaum raug dej.Kev ua qias tuaj, kev ntsuas, tsis tshua muaj zog ntawm cov kav dej yas, kev ua haujlwm tsis zoo ntawm kev tua hluav taws thiab lwm yam tsis zoo, kev tsim lub neej tuaj yeem ncav cuag 50 xyoo.Lub ntsiab tsis zoo yog tias nws yuav tsum tsis txhob khoov thaum lub installation.Thaum lub sij hawm thermal ua thiab hluav taws xob vuam txiav, txiav nto yuav tsum tau pleev xim nrog cov tsis muaj tshuaj lom ib txwm kub curing kua nplaum muab los ntawm cov chaw tsim khoom los kho qhov puas.
