Kupaka mafuta osakaniza ndi zinthu zopanda zosungunulira kwakula pamsika, makamaka chifukwa cha khama la makampani opaka mafuta ndi ogulitsa zinthu, makamaka ukadaulo wa kupopera mafuta a aluminiyamu woyenga bwino watchuka kwambiri, ndipo watenga gawo lalikulu pansi pa mikhalidwe ya chilengedwe m'malo mwa kupanga mafuta osungunuka ndi zinthu zotulutsidwa. Makampani opaka mafuta ali ndi mavuto osiyanasiyana a khalidwe chifukwa cha mikhalidwe yosiyanasiyana ya zinthu zomwe zimagwiritsidwa ntchito pazida, ntchito, zipangizo zopangira, ukadaulo wabwino komanso kugwiritsa ntchito. Pepalali likambirana za vuto lomwe lilipo, lomwe ndi kuthekera kwa thumba kutsegula ndi kusalala kwake.
Mwachitsanzo, filimu ya polyethylene yokhazikika yokhala ndi zigawo zitatu imapangidwa ndi korona, gawo lapakati logwira ntchito komanso gawo la pansi lotsekereza kutentha. Kawirikawiri, zowonjezera zotseguka ndi zosalala zimawonjezeredwa ku gawo lotsekereza lotentha. Zowonjezera zosalala zimasamutsidwa pakati pa zigawo zitatu, ndipo zowonjezera zotseguka sizimasamutsidwa.
Monga chinthu chotseka ndi kutentha, zowonjezera zotseguka ndi zosalala ndizofunikira popanga zinthu zophatikizana zosinthika. Ndizosiyana kwenikweni, koma opanga ma phukusi ambiri samamvetsetsa kuti ndi ofanana.
Chowonjezera chotsegulira chachikulu ndi silicon dioxide yomwe imapezeka m'masitolo, yomwe ndi chinthu chosapangidwa chomwe chingawonjezere kukana kwa filimuyo ku kukhuthala. Makasitomala ena nthawi zonse amapeza kuti zigawo ziwiri za thumbalo zikuwoneka ngati zachimbuuzi pakati pawo, monga magalasi awiri omwe amalumikizana. Mudzazindikira kuti ndi yosalala kutsegula ndi kupukuta, zomwe nthawi zambiri sizimakhala ndi zowonjezera zotsegulira. Ndipo ngakhale opanga mafilimu ena sagwiritsa ntchito.
Chowonjezera chosalala ndi Erucic acid amide, yomwe ndi ufa woyera womwe nthawi zambiri umamatira ku chopukutira cha lamination ndi chowongolera mu njira yopukutira ya solvent-base. Ngati chowonjezera chosalala chawonjezeredwa panthawi yopukutira yopanda solvent, china chidzafalikira ku korona pamene kutentha kwa kuchiritsa kukukwera, zomwe zimapangitsa kuti mphamvu ya kupukuta ichepe. Filimu yoyambirira ya lamination transparent PE yomwe yachotsedwa ndi yoyera, ikhoza kupukutidwa ndi minofu. Pali njira yowunikira ndikuyesa ngati mphamvu ya kupukuta yotsika ikukhudzidwa ndi zowonjezera zosalala, kuyika filimu ya laminate yotsika mu uvuni pa 80℃ kwa mphindi zisanu, kenako kuyesa mphamvu. Ngati iwonjezeka kwambiri, kwenikweni zimatsimikiziridwa kuti kuchepa kwa mphamvu ya kupukuta kumachitika chifukwa cha chowonjezera chosalala kwambiri.
Poyerekeza ndi kubwezanso kwa lamination ya solvent-base, njira yobwezanso yopanda solvent ndi yosavuta kwambiri kupeza kusamutsa ndi kufalitsa zowonjezera. Njira yachizolowezi yowunikira lamination yopanda solvent rewind ndikuwonetsetsa kuti ndi yaying'ono komanso yoyera mokwanira kuti zomatira zopanda solvent ziyende bwino. Kupanikizika kwakukulu komwe filimuyo imagwirira, zowonjezera zoterera kwambiri zimatha kusamukira ku laminated layer, kapena ngakhale kusindikiza. Chifukwa chake, timakhalabe osokonezeka ndi nkhaniyi. Chomwe tingachite ndikuchepetsa kutentha kozizira, kuchepetsa kulemera kwa chophimba, kumasula filimuyo, ndikuwonjezera zowonjezera zosalala mobwerezabwereza. Koma popanda kuwongolera bwino zomwe zili pamwambapa, guluu ndi lovuta kuchiritsa ndipo limasunga madzi. Zowonjezera zambiri sizingokhudza mphamvu yochotsa thumba la pulasitiki, komanso zimakhudza magwiridwe ake otseka otentha.
KANDA NEW MATERIALS yatulutsa gulu la zomatira kuti athetse mavutowa. Gulu la WD8117A / B lopanda zosungunulira ziwiri ndi lingaliro labwino. Lakhala likutsimikiziridwa ndi makasitomala kwa nthawi yayitali.
| Kapangidwe | Choyezera choyambirira cha kukangana | Kuchuluka kwa kukangana kokhala ndi laminated |
| PET/PE30 | 0.1~0.15 | 0.12~0.16 |
WD8117A / B ingagwiritsidwe ntchito kuthetsa vuto la mphamvu yofooka yochotsa makwinya ndi kutseka kwa kutentha chifukwa cha zowonjezera zosalala pamwamba popanda kufunikira wopanga filimu yoyambirira kuti achepetse.
Kuphatikiza apo, WD8117A/B ili ndi zinthu zina ziwiri:
1. Mphamvu yochotsa mamina a OPP / AL / PE ndi yoposa 3.5 N, pafupi kapena kuposa ya zomatira zina zosungunulira.
2. Kuchira mwachangu. Malinga ndi zomwe zanenedwa, filimu yopaka utoto imatha kufupikitsa nthawi yochira ya maola pafupifupi 8, zomwe zimawonjezera kwambiri mphamvu yopangira.
Mwachidule, kutsimikiza komaliza kwa coefficient ya friction film kuyenera kutengera ma coefficient a static friction pakati pa filimu ndi chitsulo. Malingaliro olakwika akuti ndizovuta kutsegula thumba chifukwa palibe zowonjezera zokwanira zosalala ziyenera kuzindikirika ndikukonzedwa. Tingathe kupeza zinthu zokhazikika komanso zosinthika bwino kudzera mu chidule chilichonse ndi zosintha.
