Cov txheej txheem tseem ceeb ntawm kev tsim cov yeeb yaj kiab PVC yog calendaring, tshuab moulding, thiab extrusion casting.
Daim ntawv qhia hnub: PVC resin yog tov nrog plasticizers, stabilizers, thiab lwm yam additives, ces plasticized los ntawm ib tug kneader los yog qhib tov khoom, thiab tom qab ntawd calendared rau hauv zaj duab xis siv ntau -roll calendar. Cov yeeb yaj kiab uas tsim los ntawm txoj kev no muaj cov khoom zoo thiab cov tuab tuab, ua rau nws tsim nyog rau kev tsim cov khoom siv ua yeeb yaj kiab siab - zoo, dav - dav.
Tshuab Moulding: PVC raw khoom yog ntxiv rau lub extruder, rhuab thiab melted, ces extruded los ntawm lub nplhaib tuag los ua ib tug tubular zaj duab xis dawb paug, uas yog nthuav mus rau hauv zaj duab xis siv compressed cua. Txoj kev no muaj cov cuab yeej yooj yim thiab kev nqis peev tsawg, thiab tuaj yeem tsim cov yeeb yaj kiab ntawm qhov dav sib txawv, tab sis cov yeeb yaj kiab thickness uniformity me ntsis tsis zoo.
Extrusion Casting: PVC cov khoom yog plasticized nyob rau hauv ib tug extruder thiab ces extruded los ntawm ib tug ca tuag rau hauv ib zaj duab xis, uas yog txias thiab zoo li tus rollers. Txoj kev no muaj kev ua tau zoo ntau lawm thiab tsim cov yeeb yaj kiab nrog cov pob tshab zoo, ua rau nws tsim nyog rau kev tsim cov yeeb yaj kiab nyias.
