Aogeland aluminium-yas board tuaj yeem faib ua PVDF fluorocarbon aluminium-yas board, polyester txhuas-yas board, polyurethane aluminium-yas board thiab epoxy aluminium-yas board thiab lwm yam.
Dab tsi yog qhov sib txawv ntawm PVDF fluorocarbon, polyester, polyurethane thiab epoxy aluminium yas board
PVDF fluorocarbon aluminium yas board muaj cov huab cua tsis kam, kev tiv thaiv hluav taws xob zoo heev thiab tshuaj lom neeg kuj.
Polyester aluminium puas vaj huam sib luag yog thermosetting txheej. Muaj cov roj ntsha reactive hauv nws cov qauv molecular sab hauv. Hauv qab cov cua sov, polycondensation cov tshuaj tiv thaiv ua rau muaj cov qauv tsim hluav taws xob polymer. Nws yog siv los pleev xim aluminium yas yas rau kev kho kom zoo nkauj sab hauv (tseem hu ua phab ntsa sab hauv). Aluminium-yas puas vaj huam sib luag), uas yog tus cwj pwm los ntawm kev ua tau zoo, kev nplaum zoo, ci xim, ntau yam, muaj zog kho kom zoo nkauj, thiab kev khwv nyiaj txiag, tab sis huab cua tiv thaiv tsis tuaj yeem ua tiav qhov ntev ntawm kev siv sab nraum zoov, nws tsis tshua zoo heev dua li ntawm PVDF fluorocarbon coatings.
Polyurethane aluminium puas vaj huam sib luag thiab epoxy aluminium puas vaj huam sib luag yog qhov zoo ib yam li polyester. Feem ntau hais lus, qhov kev txiav txim zoo tshaj plaws ntawm kev ua kom tiav cov kev ua tiav yog: polyurethane> polyester> epoxy; Qhov kev txiav txim zoo ntawm kev txhim kho corrosion yog: epoxy> polyurethane> polyester; qhov kev txiav txim zoo ntawm weatherability yog: polyester> polyurethane> epoxy.
Los ntawm kev txheeb xyuas saum toj no, nws tuaj yeem pom tias qhov kev ua tiav zoo tshaj plaws yog qhov zoo tshaj plaws rau polyester txhuas yas yob. Yog li ntawd, nyob rau hauv daim ntawv thov tiag tiag, lub tsho tha xim sab hauv ntawm cov xim tha xim sab hauv phab ntsa feem ntau yog polyester, polyurethane thiab epoxy feem ntau yog siv hauv cov primer lossis rov qab pleev xim. Thaum tshwj xeeb xaiv cov txheej hom, nws yog raws li kev ua tau zoo ntawm cov ntawv txhuas-yas phaj thiab txheej txheej txheej los txiav txim siab seb yuav siv hom txheej twg.
