Kraft pepala ngati zinthu wamba mu makampani kusindikiza ndi ma CD, ndiye inu mukudziwa momwe ntchitopepala la kraftmolondola?
Kugwiritsa ntchito kraft pepala
M'makampani osindikizira ndi kulongedza, mapepala a kraft amagwiritsidwa ntchito kusindikiza zivundikiro zachuma, maenvulopu, zonyamula katundu, matumba a zikalata, matumba achidziwitso, zikwama zam'manja, mabokosi amafayilo, zikwama zamafayilo, ndi zina.
Kufotokozera kwa pepala la kraft
Ambiri ntchitopepala la kraftali ndi specifications zosiyanasiyana monga 60g/m2, 70g/m2, 80g/m2, 100g/m2, 120g/m2, 150g/m2 ndipo ngakhale 250~450g/m2.
Makhalidwe a pepala la kraft
Ubwino:Pepala la Kraft lili ndi zabwino zake zolimba bwino, mawonekedwe olimba komanso olimba, osang'ambika komanso osweka, komanso osamva kuvala.
Zoyipa:kraft pepala pamwamba roughness, zosavuta kuonekera pa chamba pansi sankhani, kugwa tsitsi, de ufa chodabwitsa, whiteness, flatness, kusalala ndi osauka.
Kugwiritsa ntchito luso la pepala la kraft
① Kupachikidwa ndi kusintha chithandizo chonyowa: sitepe yoyamba yopita kumtunda wosagwirizana ndi pepala losweka lachotsedwa, sitepe yachiwiri idzakhala pepala pamwamba zonyansa, phulusa la pepala loyera, kupachikidwa kuyanika mankhwala, kuti kutentha ndi chinyezi cha pepala la kraft ndi kuchepetsa. yosindikizira msonkhano kutentha ndi chinyezi kukhala zogwirizana.Kraft pepalapambuyo atapachikidwa kuyanika mankhwala chinyezi, anaika pamwamba pa okwana pepala mbamuikha pepala chipwirikiti, ndi miyala ikuluikulu, chitsulo mbale compaction, kupewa pepala fluffy osati olimba.Kuchita zimenezi kungathandize kupewa kutuluka kwa pepala la kraft chifukwa cha chinyezi chosagwirizana chikuwonekera pazochitika za buckling pansi pa chosankha.
② kusankha chitsanzo chabwino: chifukwa cha 80g/m2 wandiweyani kraft pepala, mu pepala yobereka nozzle zambiri sangathe kuyamwa pepala, kotero pamene kraft pepala makulidwe ≥ 80g/m, ndi bwino kuti ntchito yaing'ono anayi kapena eyiti lotseguka. makina osindikizira a offset.Komanso, chifukwa yaing'ono pepala m'lifupi, zosavuta pawiri kapena Mipikisano mapepala kulephera, kapena pepala zokhotakhota mu yobereka paperboard.Ndipo ndi makina osindikizira a folio offset kapena kusindikiza kwathunthu kwa offset ≥ 80g/m ya pepala la kraft, zotsatira zake zikhala bwino.
③ kusintha makina osindikizira pepala yobereka dongosolo: makulidwe a pepala ndi lalikulu n'zosavuta kuyambitsa anagubuduza amasiya ngozi, kotero musanayambe makina osindikizira ayenera kukhala pamaso pa nkhonya kulamulira, skew kulamulira, pawiri ulamuliro, ndi zipangizo zina magetsi kusintha koyenera, kuteteza kraft pepala oposa mpukutu makina oipa.Ziyenera kusinthidwa kukula kwa kuyamwa nozzle buku kuyamwa, pepala kuyamwa nozzle ndi pepala chakudya kuyamwa nozzle ntchito m'mimba mwake ndi makulidwe ndi zazikulu mphira mphete.
④ kusunga yamphamvu yosindikizira ndi mphira yamphamvu pakati mtunda wosasinthika: kusintha mtunda wapakati pa chithunzi silinda ndi mphira yamphamvu ndi kusunga mtunda wapakati osasintha, pamene kusindikiza 250 ~ 450g / m kraft pepala, mtunda wapakati akhoza kukulitsidwa ndi 0.2 ~ 0.4 mm.kraft pepala pamwamba roughness, kusalala ndi osauka, zothina pepala ndi zochepa kwambiri kuposa copperplate pepala, offset pepala, choncho kusindikiza kraft pepala, komanso mofanana kuonjezera kusindikiza kusindikiza.Pamene kusindikizapepala la kraftmakulidwe ≥ 400g / m, mbale yosindikizira yamphamvu ndi mphira yamphamvu kusiyana 3.95mm, yamphamvu mphira ndi kufotokoza yamphamvu kusiyana kusintha kwa 3.40mm, okwana phukusi akalowa ya yosindikiza mbale yamphamvu kwa 0,65 ~ 0.75mm, okwana phukusi akalowa m'kati mwa 0,65 ~ 0.75mm mphira yamphamvu kwa 3.15 ~ 3.35mm.Ngati pepala yosindikiza kuchokera wandiweyani mpaka woonda, ayenera kutengedwa kuchokera ku mbale yosindikizira akalowa mu kuchepetsedwa makulidwe a Phukusi akalowa, kuphatikizapo mphira yamphamvu phukusi akalowa;ngati pepala kuchokera woonda mpaka wandiweyani, ayenera kukokedwa kwa yamphamvu mphira kuonjezera makulidwe a akalowa phukusi, kuphatikizapo kusindikiza mbale yamphamvu phukusi akalowa.
⑤ Kraft pepala pamwamba akhakula, lotayirira, zosavuta ufa, tsitsi, kotero pamene kusindikiza kuti scrub yamphamvu mphira ndi mbale yosindikizira yamphamvu, kupewa pepala tsitsi, pepala ufa amamatira yamphamvu mphira ndi kusindikiza mbale yamphamvu ndi kukhudza kutengerapo inki, kuchititsa zithunzi za mbale, kusowa kwa cholembera chosweka mzere.Ngati anakumana m'chilimwe pamene monochrome kusindikiza, kraft pepala tsitsi, ufa mavuto aakulu, akhoza kusindikizidwa pamaso zokutira wosanjikiza wa madzi, amene angathe kuchepetsa pepala tsitsi, ufa chodabwitsa, kuti pepala kwambiri lathyathyathya.
