Chojambula Polycarbonate

Polycarbonate (PC) imapangidwa kukhala pepala lathyathyathya mwa njira ya extrusion. Pochita extrusion, polycarbonate imayendetsedwa mosadukiza ndikugwedeza dera lotentha kwambiri komanso kuthamanga komwe imasungunuka ndikuphwanyidwa, ndipo pamapeto pake imakakamizidwa kudzera pakufa. PC akhoza extruded mu makulidwe osiyana: 0.25mm, 0.5mm, 0.7mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm ndi 2.0mm. Kawirikawiri ntchito makulidwe ndi 0.5mm, 0.7mm, 0.8mm ndi 1.0mm.

PC ikhoza kukhala yosakanikirana ndi mitundu yosiyanasiyana kuti iwonetse kuwala, kuwala, kuwala ndi kuwonekera.

Wononga extruder itha kugwiritsidwa ntchito mosiyanasiyana mawonekedwe kuti apange mawonekedwe a PC.

Coextrusion PC / PMMA. Makanema kapena mapepala amakhala ndi ma polima awiri kapena kupitilira apo amatha kupangidwa posakaniza mitsinje yosungunuka. Izi zitha kugwiritsidwa ntchito kuphatikiza zida zopangira kuphatikiza zinthu zomwe sizingapezeke mu polima imodzi.

Zingalowe zopanga PC zimatha kuteteza chitetezo ngati chigaza choteteza ubongo.

Zingalowe zopanga PC zitha kutsetsereka kuti zikhazikitse ntchito ya MIPS kuti izitha kuyendetsa mphamvu mozungulira.

Thermoforming ndi njira yotchuka popanga chisoti, chomwe chimayika pepala lopangidwa ndi silkscreened mu uvuni wa preheat, ndikuyika polycarbonate mu makina otsekemera, pepalali limatenthedwa ndi kutentha kotheka, kopangidwa ndi mawonekedwe enaake mu nkhungu, mawonekedwe osiyanasiyana azinthu ndi kutalika kungapangitse kutambasula kosiyanasiyana panthawi yopanga zingalowe, zingalowe zing'onozing'ono zomwe zimapanga PC ndizowopsa kwambiri zakutha kapena kutaya mphamvu kwa chisoti, chifukwa chake ndikofunikira kusanthula ndikusankha makulidwe olondola a polycarbonate omwe akukhudzana ndi mtundu wa chisoti komanso mayeso okhudza. ndipo adakonza kuti apange chinthu chogwiritsidwa ntchito.

Pamaso zingalowe kupanga ndondomeko, timagwiritsa ntchito wosanjikiza filimu kuteteza pa pepala polycarbonate pambuyo extrusion, filimu kuteteza Polycarbonate kuti zikanda pa EPS mu-akamaumba, ndi kuchotsa kuteteza filimu pamene chomaliza chisoti msonkhano kumapeto.
