Muchina weSINOMECH wekuisa jira rechitatu-mu-rimwe wakaratidzwa pafekitori yemubatsiri wedu, wakabatana ne-glue-free laminating adhesives kubva kuKangda—mugadziri wepamusoro wekunamira wekuChina—une mhinduro dzakasiyana-siyana uye dzinochinjika. Unotsigira-high-position three-layer aluminium foil lamination ine nzvimbo yepamusoro ine-overhead kusununguka, ine nzira pfupi inoderedza zvakanyanya njodzi yekuputsika kwejira realuminium. Pamusoro pezvo, unobata-flat paper-plastic uye plastic-plastic lamination. Kana maodha ezvivakwa zve-three-layer asina kuwanda, muchina unogona kuchinja kune-two-layer lamination kuti ikwane zvinodiwa zvakasiyana-siyana zvekugadzira. Laminator yechipiri ye-three-in-one solvent-free paper-plastic lamination inopa paper-plastic bonding, strip window uye positioning window lamination, pamwe nekugona kwe-good sheet lamination.
Chiratidziro Chekushandisa: High-Position Aluminium-Plastic Three-in-One Lamination
·Maumbirwo eLamination: 12μm PET / 7μm AL / 55μm PE
·Chinonamira: Kangda WD8262A/B Chinonamira Chisina Zvinyungudutsi Chinonamira
WD8262A/B, yakagadzirwa yakazvimirira neShanghai Kangda, ndiyo yekutanga chinamira chisina solvent-free chinogadzirwa muChina chine zvikamu zviviri chinoshanda zvakanaka chakatsaurirwa kune aluminium foil lamination. Yakagadzirirwa PET/AL composites yakadhindwa zvizere, inoshandisa tekinoroji yeKangda New Materials' mature aluminium foil lamination kugadzira matemplate asina kuremara asina mavara machena mushure mekuiswa. Mafirimu apera anoramba kupiswa nekupiswa pa121°C kwemaminitsi makumi mana. Kuti ienderane nezvinangwa zvenyika zvekuderedza kabhoni uye kuderedza kusvibiswa kwezvakatipoteredza, vagadziri vakuru vemapakeji anochinjika muChina vari kutsiva zvishoma nezvishoma zvigadzirwa zvealuminium foil zvakaomeswa nelaminated nezvimwe zvinoshandiswa pakuiswa kwelamination zvisina solvent.
Pfungwa Dzakakosha dzeKudzora Unyanzvi hwePET+AL+PE Maitiro Ekugadzira Lamination Yezvikamu Zvitatu
PET+AL+PE chimiro chekare chine miganho yakawanda. PET inopa simba remuchina uye kugona kudhindwa; aluminium foil inoita mabasa ekudzivirira mativi anosanganisira kuvharira chiedza, kudzivirira okisijeni uye kudzivirira mhute yemvura; PE layer yemukati inobvumira kuvharwa kwekupisa uye kusangana zvakananga nezviri mukati. Chimiro ichi chinoshandiswa zvakanyanya mukudya, kurongedza makemikari ezuva nezuva uye mishonga. Maitiro e lamination anoda kunyatsorongeka—kudzora zvisina kunaka kweruzivo rwehunyanzvi kuchaita kuti pave nezvikanganiso zvakaita se delamination, mabhuru, makwinya, aluminium foil cracking uye kusavhara zvakanaka kupisa. Pazasi pane zvakakosha zvekudzora maitiro:
1. Substrate Pretreatment: Hwaro hweLamination Quality
Kushanda kwepamusoro pezvinhu zvose zvepasi kunofanirwa kudzorwa zvakasimba.
• Mafirimu ePET anoda kurapwa kwekorona kuti asvike pazvinodiwa pakumanikidzwa kwepamusoro. Guruva nemagetsi asingachinji pamusoro zvinofanira kubviswa kudzivirira kuputira kusina kuenzana uye kuparadzwa kwezvikamu zvakasiyana.
• Foil yearuminiyamu yakatetepa, yakapfava, inokurumidza kuoxidation uye yakafukidzwa nemafuta anotenderera. Kuchenesa nekudzima mafuta pakutanga zvinosungirwa, zvichiteverwa ne corona activation kuti pave nekumanikidzwa kwepamusoro kwe ≥38 mN/m. Foil yearuminiyamu ine oxidation, maburi kana creases inorambidzwa zvachose, sezvo zvikanganiso zvakadaro zvichikanganisa mashandiro ekudzivirira.
• Mafirimu emukati mePE anofanira kuomeswa zvizere nehunyoro hwakadzikama huri pasi pe0.05% kudzivirira kuchena uye maburi mushure mekuputira. Maburi epamusoro anofanira kubviswa kuti pave nechokwadi chekuti anobata zvakanaka.
2. Kudzora Kushushikana Kwakarongwa Munguva Yekugadzira (Chinonyanya Kukosha)
Mutemo wekusimbaradzana kwemuviri unofanirwa kushandiswa padanho rega rega:
• PET ine kusimba kwakanyanya; kugadzikana kwekusunungura kwakaiswa pa90–110 N nekumhanya kwakasimba, kwakafanana kuti nzvimbo dzakati sandara dzisatsauke.
• Foil yearuminiyamu haina simba rakawanda uye inotambanuka zviri nyore kana yabatwa nechisimba. Simba rakaderera uye rakagadzikana re40–70 N rinodiwa. Kutanga kwemuchina, kudzima uye kugadzirisa kumhanya kunofanirwa kuitwa zvishoma nezvishoma kudzivirira kutsemuka kudiki uye kushanduka kwekumanikidzwa kunokonzerwa nekudhonza simba ipapo ipapo.
• Mafirimu ePE akapfava anoda kugadzikana kwakaderera kudzivirira kuderera mushure mekutambanudza, izvo zvinotungamira mukudonha kwechigadzirwa chapera uye kupatsanurwa kwezvikamu. Kugadzikana kwemhepo kunoshandisa chimiro chinodzikira chegradient kudzivirira makwinya emukati uye kutsvedza kwezvinhu.
3. Kufananidza Kwakarurama KwemaParameters Ekupenda uye Ekudzikisa
Kuisa lamination yakaoma ndiyo nzira inofarirwa neanamatiki epolyurethane anoenderana nezvikamu zviviri. Kudzora kwakasimba kwehuwandu hwekusanganisa anamatiki uye viscosity kunoita kuti pave nekushanda kwakanaka kwekuenzanisa.
• Huremu hwakafanana hwekufukidza hunochengetwa pa 3–5 g/m². Kuvhara kusina kukwana kunoita kuti pave nesimba risina simba rekusunga, nepo kufukidza kwakawandisa kuchikonzera kuungana kwenamira, kuvharika uye kunhuwa kunoramba kuripo.
• Kurongeka kwe lamination sequence: Bond PET ne aluminiyamu foil kutanga, yozora kwemaawa 2-4, wozora laminate ne PE. Lamination yakawanda panguva imwe chete ichaita kuti kunamira kusina kuenzana.
• Kupisa kwelamination kunogadzikana pa60–80°C nekumanikidzwa kwelamination kwakaringana. Kupisa kwakaderera kunoita kuti namatidziro isanyatsogadzirwa zvakanaka; kupisa kwakanyanya kunokonzera kushanduka kwekupisa kwemafirimu uye kupwanyika kwefoil yealuminium.
4. Maitiro Ekugadzirisa Zvakakomba uye Mushure mekugadzirisa
Zvigadzirwa zve laminated zvakapedzwa zvishoma zvinoendeswa muimba yekupisa inogara ichidziya, inochengetwa pa40–50°C kwemaawa 24–48 kuti zvikwanise kubatanidza nekunamira zvakakwana. Izvi zvinovandudza zvikuru simba remakanda epakati pezvikamu uye zvinobvisa njodzi dzekubvisa ganda kwenguva refu.
Kucheka nekugadzira mabhegi kunoitwa chete mushure mekunyatsopera. Zvinhu zvakaoma zvakapinza hazvifanirwe kubata jira realuminium foil kudzivirira kukuvara kweburi.
Zvigadzirwa zvakapedzwa zvinofanira kuchengetwa munzvimbo dzisingapindi chiedza, dzakaoma, kure nekupisa kwakanyanya uye hunyoro kudzivirira kuoxidation yealuminium foil uye kutadza kwehydrolysis yeglue. Kubviswa kweguruva kwakazara kunomanikidzwa mukati meworkshop yese kudzivirira kubatwa kweguruva pakati pezvikamu zvakanyungudutswa, izvo zvinokonzera kucheka kwemavara nemabubbles, zvichiita kuti zvigadzirwa zvakapedzwa zvisvike padanho rekudzivirira uye kugadzikana kwelamination.
