Cov txheej txheem ntawm cov ntawv PC yog extrusion molding, thiab cov khoom tseem ceeb yuav tsum yog extruder. Vim tias kev ua haujlwm ntawm PC resin nyuaj, qhov yuav tsum tau ua rau cov khoom siv ntau lawm yog siab. Feem ntau ntawm cov khoom siv rau kev tsim khoom hauv tsev ntawm PC boards yog imported, feem ntau yog los ntawm ltalis, lub teb chaws Yelemees thiab Nyiv. Feem ntau ntawm cov resins siv yog imported los ntawm GE nyob rau hauv teb chaws USA thiab Baver nyob rau hauv lub teb chaws Yelemees. Ua ntej extrusion, cov khoom yuav tsum nruj nreem ziab kom nws cov dej noo qis dua 0.02% (feem ntau). Cov khoom siv extrusion yuav tsum tau nruab nrog lub tshuab nqus tsev kom qhuav hoppers, qee zaum ob peb xav tau hauv series. Lub cev kub ntawm extruder yuav tsum tau tswj ntawm 230-350 ° C, maj mam nce los ntawm rov qab mus rau pem hauv ntej. Lub taub hau siv yog lub tiaj tus extruded slit hom taub hau. Lub extrusion yog ces txias los ntawm calendering. Nyob rau hauv xyoo tas los no, txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm PC board anti-UV kev ua tau zoo, feem ntau nyob rau hauv PC board nto npog nrog nyias txheej ntawm anti-UV (UV) additives, uas yuav tsum muaj ob txheej txheej co-extrusion, uas yog, txheej txheej saum npoo muaj UV additives thiab hauv qab txheej tsis muaj UV additives. Ob txheej no yog laminated hauv lub taub hau thiab extruded rau hauv ib qho. Hom kev tsim lub taub hau no yog qhov nyuaj dua. Qee lub tuam txhab tau txais qee cov thev naus laus zis tshiab, xws li Bayer's co-extrusion system nrog lub twj tso kua mis tsim tshwj xeeb thiab kev sib koom ua ke thiab lwm yam thev naus laus zis. Tsis tas li ntawd, muaj qee lub sijhawm uas yuav tsum muaj PC boards kom tsis muaj dej tsis muaj dej, yog li yuav tsum muaj cov tshuaj tiv thaiv drip rau sab nraud. Kuj tseem muaj PC boards uas yuav tsum muaj cov txheej txheem tiv thaiv UV ntawm ob sab, thiab cov txheej txheem tsim khoom ntawm cov PC boards yog qhov nyuaj dua.
