Polyester chips CZ-302

Lus piav qhia luv luv:

"JADE" Hom Copolyester "CZ-302" 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 cov yam ntxwv ua tau zoo, ua haujlwm qis, dav dav hauv kev ua, zoo tshaj plaws pob tshab thiab siab hauv cov khoom tiav. Hauv kev ua lub raj mis, cov khoom lag luam muaj me me degradation thiab cov ntsiab lus ntawm acetaldehyde tsawg. Thaum ua kom muaj kev nyab xeeb thiab kev nyiam huv, nws tuaj yeem ua kom muaj qhov sib txawv ntawm cov dej huv huv, dej ntxhia thiab dej distilled.
