Izindaba - Inqubo yokukhiqiza yeshidi le-polycarbonate

Inqubo yokukhiqiza yebhodi le-PC i-extrusion molding, futhi imishini eyinhloko edingekayo i-extruder.Ngoba ukucubungula kwe-PC resin kunzima kakhulu, kudinga imishini yokukhiqiza ephakeme.Iningi lemishini yasekhaya yokukhiqiza amabhodi e-PC ingenisiwe, iningi eziphuma e-Italy, eJalimane nase-Japan.Iningi lama-resin asetshenziswayo athunyelwa kwa-GE e-United States nase-Baver e-Germany.Ngaphambi kokukhipha, impahla kufanele yomiswe ngokuqinile ukuze okuqukethwe kwayo kwamanzi kube ngaphansi kuka-0.02% (ingxenye enkulu) .Imishini ye-extrusion kufanele ifakwe i-vacuum drying hopper, ngezinye izikhathi eziningana ngochungechunge.Ukushisa komzimba we-extruder kufanele kulawulwe ku-230-350 ° C, kancane kancane kukhule kusukela emuva kuya phambili.Ikhanda lomshini elisetshenzisiwe yi-extrusion flat. slit ikhanda lomshini.Ngemuva kwe-extrusion, i-calender futhi ipholile.Eminyakeni yakamuva,

Ukuze kuhlangatshezwane nezidingo zokusebenza kwebhodi le-PC lokulwa ne-ultraviolet, Ungqimba oluncane oluqukethe izithasiselo zokulwa ne-ultraviolet (UV) luvamise ukusetshenziswa phezu kwebhodi le-PC.Lokhu kudinga ukusetshenziswa kwenqubo yokukhishwa ngokubambisana kwezingqimba ezimbili, Okusho ukuthi, ungqimba olungaphezulu luqukethe abasizi be-UV futhi isendlalelo esingezansi asiqukethe abasizi be-UV.Lezi zingqimba ezimbili zihlanganiswa ekhaleni, Iba yinye ngemva kokukhishwa.Lolu hlobo lokuklanywa kwekhanda luyinkimbinkimbi kakhulu.Ezinye izinkampani zithole ubuchwepheshe obusha, futhi i-Bayer isebenzise ubuchwepheshe obufana namaphampu ancibilikisayo aklanywe ngokukhethekile kanye nama-confluencers ohlelweni lwe-coextrusion.Ngaphezu kwalokho, kwezinye izikhathi, kuba namazolo ebhodini le-PC.
Ngakho-ke kufanele kube khona okokuvikela amazolo ngakolunye uhlangothi.Amanye amabhodi e-PC adinga ukuba nezingqimba ezimelene ne-ultraviolet nhlangothi zombili,Lolu hlobo lwenqubo yokukhiqiza ibhodi le-PC luyinkimbinkimbi kakhulu.
