zosungunulira-free lamination wakhwima mu msika, makamaka chifukwa cha khama ma CD mabizinesi ndi ogulitsa zinthu, makamaka koyera zotayidwa lamination luso la retorting wakhala ambiri kutchuka, ndipo watenga sitepe yaikulu pansi pa chilengedwe zikhalidwe m'malo zosungunulira chikhalidwe- Base lamination ndi extruded lamination kupanga.Mabizinesi onyamula katundu amakumana ndi zovuta zosiyanasiyana zamakhalidwe chifukwa chamitundu yosiyanasiyana yazogulitsa pazida, magwiridwe antchito, zida, ukadaulo wapamwamba komanso kugwiritsa ntchito.Pepalali lilankhula za vuto lomwe liripo, lomwe ndi kuthekera kwa thumba kutseguka komanso kusalala kwake.
Mwachitsanzo, wokhazikika atatu wosanjikiza extruded polyethylene filimu wapangidwa korona wosanjikiza, pakati zinchito wosanjikiza ndi pansi matenthedwe chisindikizo wosanjikiza.Kawirikawiri, zowonjezera zotsegula ndi zosalala zimawonjezeredwa pazitsulo zotentha zosindikizira.Zowonjezera zosalala zimasamutsidwa pakati pa zigawo zitatu, ndipo kutsegulira kowonjezera sikuli.
Monga chinthu chosindikizira chotentha, zowonjezera zotsegula ndi zosalala ndizofunikira popanga ma composites osinthasintha.Ndizosiyana kwenikweni, koma opanga ma CD ambiri samamvetsetsa kuti ndizofanana.
Chowonjezera chotsegulira ndi silicon dioxide yomwe imapezeka pamalonda, yomwe ndi chinthu chachilengedwe chomwe chingapangitse kuti filimuyi isakane kukhuthala.Makasitomala ena nthawi zonse amapeza kuti zigawo ziwiri za thumba zimawoneka ngati zakuda pakati pawo, ngati magalasi awiri omwe amadumphira.Mudzawona kuti ndi yosalala kuti mutsegule ndi kupukuta, zomwe nthawi zambiri zimasowa pakutsegulira zowonjezera.Ndipo ngakhale opanga mafilimu ena sagwiritsa ntchito.
Chowonjezera chosalala bwino ndi Erucic acid amide, yomwe ndi ufa woyera womwe nthawi zambiri umamatira ku lamination roller ndi guide roller muzosungunulira-base laminating process.Ngati chowonjezera chosalala chiwonjezedwa panthawi ya zosungunulira zopanda zosungunulira, zina zimabalalika mpaka kusanjikiza kwa corona pomwe kutentha kwa machiritso kumachulukira, zomwe zimapangitsa kuchepa kwamphamvu kwa peeling.The original lamination mandala filimu PE peeled ndi woyera, akhoza misozi ndi minofu.Pali njira yowunikira ndikuyesa ngati kuchepetsedwa kwamphamvu kwa peeling kumakhudzidwa ndi zowonjezera zowonjezera zosalala, ndikuyika filimu yotsika ya laminate mu uvuni pa 80 ℃ kwa mphindi zisanu, ndikuyesa mphamvu.Ngati chiwonjezeke kwambiri, zimaganiziridwa kuti kuchepa kwa mphamvu ya peeling kumachitika chifukwa cha zosalala kwambiri.
Poyerekeza ndi rewind wa zosungunulira-m'munsi lamination, zosungunulira-free lamination njira n'zosavuta kukwaniritsa zina kutengerapo ndi kubalalitsidwa.Wachizolowezi njira kuweruza zosungunulira free laminating rewind ndi kuonetsetsa kuti yaying'ono ndi mwaukhondo kulola bwino yachiwiri yosalala otaya zosungunulira wopanda zomatira.Kuthamanga kwapamwamba kwa wodzigudubuza filimu kumakwanira, zowonjezera zowonjezera zowonjezereka zimatha kusamukira ku laminated wosanjikiza, kapena ngakhale kusindikiza.Chifukwa chake, tikhalabe osokonezeka pankhaniyi.Zomwe tingachite ndi kuchepetsa kutentha kwa machiritso, kuchepetsa kulemera kwake, kumasula filimuyo, ndikuwonjezera zowonjezera zosalala mobwerezabwereza.Koma popanda kuwongolera bwino pamwamba, zomatirazo zimakhala zovuta kuchiza ndikusunga madzi.Zowonjezera zambiri sizingangokhudza mphamvu ya thumba la pulasitiki, komanso zimakhudza ntchito yake yosindikiza kutentha.
KANDA NEW MATERIALS yatulutsa zomatira zingapo kuti zithetse mavutowa.WD8117A / B zomatira zopanda zosungunulira zapawiri ndiupangiri wabwino.Zatsimikiziridwa ndi makasitomala kwa nthawi yayitali.
| Kapangidwe | Coefficient yoyambirira ya kukangana | Laminated coefficient ya kukangana |
| PET/PE30 | 0.1-0.15 | 0.12-0.16 |
WD8117A / B angagwiritsidwe ntchito kuthetsa vuto la osauka peeling mphamvu ndi matenthedwe kusindikiza ntchito chifukwa monyanyira zina yosalala pamwamba popanda amafuna choyambirira filimu wopanga kuchepetsa iwo.
Kuphatikiza apo, WD8117A/B ilinso ndi zina ziwiri:
1. Kuchucha mphamvu ya OPP / AL / PE ndi pamwamba 3.5 N, pafupi kapena apamwamba kuposa zomata zosungunulira-base laminating.
2. Kuchiritsa msanga.Pansi pamikhalidwe yomwe ikuyembekezeredwa, filimu yopangira laminating imatha kufupikitsa nthawi yochiritsa pafupifupi maola 8, zomwe zimakweza kwambiri kupanga bwino.
Mwachidule, kutsimikiza komaliza kwa friction coefficient of composite coefficient kuyenera kutengera ma static friction coefficients pakati pa filimu ndi mbale yachitsulo.Malingaliro olakwika akuti ndizovuta kutsegula thumba chifukwa palibe zowonjezera zowonjezera zosalala ziyenera kuzindikirika ndikuwongolera.Titha kukwaniritsa kukhazikika komanso kusinthika kwapang'onopang'ono popanga chidule chilichonse ndikusintha.
