Polyester chips CZ-302
Hom
"JADE" Brand, Copolyester.
Kev piav qhia
"JADE" Hom Copolyester "CZ-302" lub raj mis qib polyester chips nta cov hlau hnyav hnyav, cov ntsiab lus ntawm acetaldehyde, xim zoo, ruaj khov viscosity. acetaldehyde thaum ua kom muaj kev nyab xeeb thiab kev nyiam huv, nws tuaj yeem ua kom muaj qhov sib txawv ntawm cov dej huv, dej ntxhia thiab dej distilled.
Daim ntawv thov
Lawv tsim nyog rau kev ua cov ntim ntim rau cov dej ntshiab, dej ntxhia dej, dej distilled, dej haus, tsw thiab khoom qab zib ntim, pleev lub raj mis thiab cov ntaub ntawv PET
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 275-293 ° C.
