Polyester chips CZ-333
Hom
"JADE" Brand, homopolyester.
Kev piav qhia
"JADE" Homopolyester "CZ-333" lub raj mis qib polyester chips nta cov ntsiab lus hlau hnyav, cov ntsiab lus ntawm acetaldehyde, xim zoo, ruaj khov viscosity thiab zoo rau kev ua haujlwm. 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 nyob rau hauv lub raj mis, muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm lub raj mis ntawm li 90 ° C thiab tiv thaiv dej qab zib los ntawm discoloration los yog oxidization nyob rau hauv cia lub sij hawm thiab tiv thaiv lub deformation ntawm lub fwj.
Daim ntawv thov
tshwj xeeb yog siv rau lub raj mis kub ntim raws li cov dej tshuaj yej, cov kua txiv hmab txiv ntoo thiab lwm yam dej haus nruab nrab yuav tsum tau muab lub raj mis kub rau kom tsis muaj menyuam.
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 165-185 ° C, 4-6 teev nyob rau lub sij hawm, dew point kub hauv qab -40 ℃ . Qhov ntsuas kub zoo li ntawm 285-298 ° C.
