Qhov rai zaj duab xispolyester raws li zaj duab xisyog tsuas yog siv rau automotive thiab architectural iav zaj duab xis. Nws yog cov yeeb yaj kiab ua haujlwm siab nrog polyester ua cov khoom tseem ceeb, nrog rau lub teeb pom kev zoo thiab UV tsis kam. Nws cov qauv feem ntau yog tsim los ntawm ntau txheej ntawm polyester zaj duab xis, ua kom lub cev muaj zog thiab ua haujlwm ntev. Cov yeeb yaj kiab no tsis yog qhov hnyav xwb, tab sis kuj muaj qhov zoo adhesion thiab thermal stability, thiab tuaj yeem hloov mus rau ntau yam kev nyab xeeb.
Daim duab schematic ntawm cov pa 8-txheej qhov rais zaj duab xis qauv yog qhia hauv qab no.
PET zaj duab xisdaim duab qauv
Peb qhov rais zaj duab xispolyester puag zaj duab xisFeem ntau suav nrog peb tus qauv: SFW11 nrog lub ntsiab txhais, SFW21 nrog siab txhais thiab SFW31 nrog ultra-siab txhais.
Ntawm lawv, cov yam ntxwv tseem ceeb ntawm SFW11 qauv yog: qis nto roughness, zoo flatness, zoo kub kuj thiab zoo nto zoo.
Daim ntawv qhia
Lub thickness ntawm SFW11 suav nrog: 25μm, 36μm thiab 50μm thiab lwm yam.
