Polyester chips CZ-318
Hom
"JADE" Brand, Copolyester.
Kev piav qhia
"JADE" Hom Copolyester "CZ-318" lub raj mis qib polyester chips nta cov hlau hnyav, cov ntsiab lus ntawm acetaldehyde, xim zoo, viscosity ruaj khov. kev ua haujlwm kub tsawg, dav dav hauv kev ua, zoo heev transparency, siab zog thiab siab cov khoom tiav.
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 haus carbonated, cov ntim me me uas siv tau roj fwj cawv fwj, tshuaj fwj, ntxuav cov tshuaj pleev ib ce fwj, lub raj mis lub qhov ncauj thiab PET nplooj 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.
