Kev tsim ntawm PVC zaj duab xis
Feem ntau muaj ob txoj hauv kev los ua cov yeeb yaj kiab pvc: extrusion calendering thiab casting.Extrusion calendering yog txoj kev tshaj plaws.
PVC zaj duab xis tuaj yeem muab faib ua ob pawg loj: mos thiab semi-rigid.Kev ua lag luam xav tau rau cov yeeb yaj kiab PVC semi-rigid mus txog yuav luag ob feem peb.
Cov ntaub ntawv mos PVC feem ntau yog siv rau cov ntaub pua rooj, cov ntaub ntawv tsis yog cov ntaub, thiab cov hnab.Vim tias cov ntawv mos PVC lossis zaj duab xis muaj cov softeners, nws yooj yim los ua nkig thiab nyuaj rau khaws cia.Qhov no txwv nws txoj kev thov.
Rigid PVC tsis muaj softeners.Nws yog yoog raws, yooj yim rau kev tsim, tsis yooj yim rau nkig, tsis muaj tshuaj lom thiab tsis muaj kuab lom.Nws muaj lub sijhawm khaws cia ntev, kub tsis kam, tsis yooj yim rau yaj.Nws yog printable, thiab muaj zoo inking nyhuv.Nws yog qhov muaj txiaj ntsig zoo thiab siv ntau heev.Lub tsev thiab hluav taws xob siv 60% ntawm PVC yas zaj duab xis thiab cov ntawv txheeb.Ntau lub lag luam ntim khoom kuj tseem siv cov khoom siv PVC zoo heev.Kuj tseem muaj ob peb daim ntawv thov, xws li folding lub thawv ntawv sau, laser txiav, thiab muab faib boards thiab lwm yam.
