Roj Lub raj mis Qib PET Resin (PET)
Khoom Taw Qhia
Roj lub raj mis qib polyester chips tau tsim thiab tsim raws li lub zog siab dua, kev sib cais, pob tshab thiab kev ua haujlwm zoo dua thiab lwm yam tshwj xeeb siv cov khoom xav tau los ntawm lub raj mis rau cov dej haus carbonated, cov khoom siv me me uas siv tau cov roj fwj cawv fwj, tshuaj fwj, tshuaj pleev ib ce fwj, lub raj mis lub qhov ncauj thiab cov ntawv PET.
Cov khoom lag luam muaj cov ntsiab lus tsis tshua muaj hlau hnyav, cov ntsiab lus tsis tshua muaj acetaldehyde, xim zoo, viscosity ruaj khov.Nrog rau daim ntawv qhia txheej txheem tshwj xeeb thiab cov thev naus laus zis ntau lawm, cov khoom lag luam muaj qhov pom tseeb zoo heev thiab tuaj yeem ua tiav cov tuab thiab ntau hom kev ua haujlwm ntawm cov ntim me me tuaj yeem siv tau roj fwj, cawv fwj, tshuaj fwj thiab nplooj ntawv, muaj cov yam ntxwv ntawm kev ua haujlwm qis, dav. Scope nyob rau hauv kev ua, zoo heev pob tshab, siab zog thiab siab tiav cov khoom tus nqi.
