Polyester chips CZ-318
Hom
"JADE" Brand, Copolyester.
Kev piav qhia
"JADE" Hom Copolyester "CZ-318" lub raj mis qib polyester chips nta cov ntsiab lus hlau hnyav, tsis tshua muaj cov ntsiab lus ntawm 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.
Daim ntawv thov
Nws yog 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 qab zib, cov roj ntim me me ntim cov roj fwj dej cawv, cov tshuaj fwj, ntxuav cov tshuaj pleev ib ce fwj, lub raj mis lub qhov ncauj thiab PET ntawv.
Hom kev ua haujlwm
Kev ziab yog tsim nyog ua ntej cov txheej txheem yaj los tiv thaiv cov resin los ntawm hydrolysis. Tej yam kev mob ziab yog huab cua kub ntawm 160-180 ° C, 4-6 teev nyob rau hauv lub sij hawm, dew point kub hauv qab -40 ° C. Qhov ntsuas kub zoo li ntawm 275-295 ° C.
