Cov ntawv polyester CZ-302
Hom
"JADE" Hom, Copolyester.
Kev piav qhia
Cov khoom siv "JADE" Hom Copolyester "CZ-302" lub raj mis qib polyester chips muaj cov hlau hnyav tsawg, cov 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 cov yam ntxwv ua haujlwm zoo heev, qhov kub ua haujlwm tsawg, dav hauv kev ua haujlwm, pob tshab zoo heev thiab cov khoom tiav sai. Thaum ua lub raj mis, cov khoom muaj qhov puas tsuaj me me thiab cov acetaldehyde tsawg. Thaum ua kom muaj kev nyab xeeb thiab kev huv, nws tuaj yeem khaws cov saj tshwj xeeb ntawm cov dej huv, dej ntxhia thiab dej distilled.
Cov ntawv thov
Lawv yog cov tsim nyog rau kev ua cov fwj ntim rau dej ntshiab, dej ntxhia ntuj, dej distilled, dej haus, tsw qab thiab khoom qab zib, lub raj mis pleev xim thiab cov ntawv PET.
Cov xwm txheej ua tiav ib txwm muaj
Yuav tsum tau ziab ua ntej ua cov khoom yaj 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, lub sijhawm nyob 4-6 teev, qhov kub ntawm cov dej noo hauv qab -40 ℃. Qhov kub ntawm lub thoob feem ntau yog li 275-293 ° C.
