Cov txheej txheem ntawm PC board yog extrusion molding, thiab cov cuab yeej tseem ceeb yuav tsum yog extruder.Vim tias cov txheej txheem ntawm PC resin yog qhov nyuaj dua, nws yuav tsum muaj cov khoom siv ntau dua. Feem ntau ntawm cov khoom siv hauv tsev rau kev tsim cov PC boards yog imported, feem ntau. Ntawm cov uas tuaj ntawm ltalis, Lub teb chaws Yelemees thiab Nyiv.Feem ntau ntawm cov resins siv yog imported los ntawm GE nyob rau hauv lub tebchaws United States thiab Baver nyob rau hauv lub teb chaws Yelemees. Ua ntej extruding, cov khoom yuav tsum nruj me ntsis qhuav kom nws cov dej cov ntsiab lus yog qis dua 0.02% (feem ntau) .Cov khoom siv extrusion yuav tsum tau nruab nrog lub tshuab nqus tsev kom qhuav, qee zaum ntau hauv series.Qhov kub ntawm lub cev ntawm extruder yuav tsum tau tswj ntawm 230-350 ° C, maj mam nce los ntawm rov qab mus rau pem hauv ntej.Lub tshuab taub hau siv yog ib tug ca extrusion. tshuab taub hau.Tom qab extrusion, nws yog calendered thiab txias.Nyob rau hauv xyoo tas los no,

Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm PC board tiv thaiv kev ua haujlwm ultraviolet, Ib txheej nyias uas muaj cov tshuaj tiv thaiv ultraviolet (UV) feem ntau siv rau saum npoo ntawm PC board.Qhov no yuav tsum tau siv ob txheej txheej co-extrusion, Ntawd yog, txheej txheej saum npoo muaj UV pab thiab txheej hauv qab tsis muaj UV pab.Ob txheej yog compounded nyob rau hauv lub qhov ntswg, Nws ua ib tug tom qab extrusion.Hom kev tsim lub taub hau no yog qhov nyuaj dua.Qee lub tuam txhab tau siv qee cov thev naus laus zis tshiab, thiab Bayer tau siv cov thev naus laus zis xws li tsim tshwj xeeb tsim cov twj tso kua mis thiab cov confluencers hauv cov txheej txheem coextrusion.Ntxiv rau qee lub sijhawm, muaj cov kua dej poob rau ntawm PC board.
Yog li yuav tsum muaj cov txheej txheem los tiv thaiv dew ntawm sab nraud.Qee lub PC boards yuav tsum muaj cov txheej txheem tiv thaiv ultraviolet ntawm ob sab, hom PC board ntau lawm txheej txheem yuav nyuaj dua.
