Cov txheej txheej ntawm cov xim-coated aluminium coils tau muab faib ua polyester-coated aluminium coils (PE) thiab fluorocarbon-coated aluminium coils (PVDF). Cov txheej txheej polyester tsim nyob rau saum npoo ntawm txhuas phaj tom qab ntau qhov ci thiab pleev xim tuaj yeem tsim cov yeeb yaj kiab txuas txuas ntxiv, uas muaj cov yam ntxwv ntawm kev tiv thaiv thiab kho kom zoo nkauj. Nws yog UV resistant xim. Polyester resin siv lub siab molecular polymer uas muaj ester bonds nyob rau hauv lub ntsiab saw raws li ib tug monomer, thiab ntxiv alkyd resin.
UV absorbers tuaj yeem muab faib ua matte thiab high-gloss series raws li glossiness. Nws muab cov yeeb yuj aluminium cov khoom nplua nuj xim, zoo gloss, zoo smoothness, superior zoo nkauj thiab xav, thiab ntxiv ib qho kev nkag siab ntawm txheej thiab peb-dimensionality. Xim-coated aluminium coils tuaj yeem tiv thaiv UV rays, cua, nag, te, thiab daus; vim qhov sib txawv ntawm qhov kub thiab txias, lub voj voog khov-thaw, corrosive gases, thiab cov kab mob, cov txheej tuaj yeem ua lub luag haujlwm tiv thaiv. Tshwj xeeb tshaj yog tsim rau sab hauv kho kom zoo nkauj thiab billboards.
