Kub-filled raj qib PET Resin
Khoom Taw Qhia
Kub-Filled lub raj mis qib polyester chips tau tsim thiab tsim tshwj xeeb rau cov fwj kub ntim raws li cov tshuaj yej dej qab zib, txiv hmab txiv ntoo-kua txiv thiab lwm yam dej haus nruab nrab yuav tsum tau muab lub raj mis kub kom tsis muaj menyuam.
Cov khoom lag luam muaj cov ntsiab lus tsis tshua muaj hlau hnyav, cov ntsiab lus qis ntawm acetaldehyde, xim zoo, ruaj khov viscosity thiab zoo rau kev ua haujlwm.Nrog rau daim ntawv qhia txheej txheem tshwj xeeb thiab cov thev naus laus zis ntau lawm, cov khoom lag luam, thaum raug thermoformed hauv SIPA, SIDEL, ASB thiab lwm yam. thawj lub raj mis ua tshuab nyob rau hauv tej yam kev mob, muaj tropism npaum li cas, ruaj khov crystallinity thiab zoo fluidity nrog tsawg-tso tawm tus nqi nyob rau hauv tag nrho lub raj mis, ruaj khov thermal contraction tus nqi thiab siab tiav cov khoom lag luam hauv kev ua lub raj mis, tuaj yeem ua tau raws li qhov yuav tsum tau ntim hauv lub raj mis ntawm li 90 ° C thiab tiv thaiv cov dej qab zib los ntawm discoloration los yog oxidization nyob rau hauv lub sij hawm cia thiab tiv thaiv lub deformation ntawm lub fwj.

Hom kev ua haujlwm
Kev ziab yog tsim nyog ua ntej cov txheej txheem yaj los tiv thaiv cov resin los ntawm hydrolysis.Cov kev ua kom qhuav yog huab cua kub ntawm 165-185 ° C, 4-6 teev nyob rau lub sijhawm, dew point kub hauv qab -40 0C.
Qhov ntsuas kub zoo li ntawm 285-298 ° C.
