Cov ntawv polyester CZ-318
Hom
"JADE" Hom, Copolyester.
Kev piav qhia
Cov khoom siv "JADE" Hom Copolyester "CZ-318" lub raj mis qib polyester chips muaj cov hlau hnyav tsawg, acetaldehyde tsawg, xim zoo, viscosity ruaj khov. Nrog rau cov txheej txheem tshwj xeeb thiab cov thev naus laus zis tsim khoom siab heev, cov khoom muaj kev pom tseeb zoo heev thiab tuaj yeem ua tau raws li qhov tuab thiab ntau yam kev xav tau ntawm cov fwj roj noj tau me me, fwj cawv, fwj tshuaj thiab ntawv, muaj cov yam ntxwv ntawm qhov kub ua haujlwm qis, dav hauv kev ua haujlwm, pom tseeb zoo heev, muaj zog siab thiab cov khoom tiav tiav sai.
Cov ntawv thov
Nws yog tsim thiab tsim tawm raws li lub zog siab dua, kev sib cais, pob tshab thiab kev ua haujlwm zoo dua thiab lwm yam. Cov khoom siv tshwj xeeb uas xav tau los ntawm lub raj mis rau cov dej haus carbonated, cov roj me me noj tau, cov fwj cawv, cov fwj tshuaj, cov fwj ntxuav cov tshuaj pleev ib ce, cov fwj qus thiab cov ntawv PET.
Cov xwm txheej ua tiav ib txwm muaj
Ua ntej ua cov khoom yaj, yuav tsum ziab kom qhuav kom tiv thaiv cov roj hmab kom tsis txhob tawg. Cov xwm txheej ziab ib txwm muaj yog qhov kub ntawm huab cua ntawm 160-180 ° C, nyob rau 4-6 teev, qhov kub ntawm cov dej noo hauv qab -40 ℃. Qhov kub ntawm lub thoob feem ntau yog li 275-295 ° C.
