Leli phepha ligxile ezintweni ezimbaxambili zokunamathelisa i-laminating ezingancibiliki, elidingida impahla yokulinganisa yemikhiqizo engancibiliki.
1. Incazelo Eyisisekelo Yezakhiwo Zokulinganisa
Isakhiwo sokulinganisa amandla okunamathela ukuze afinyelele ngokulinganayo nangokushelela phezu kwama-substrates.
2. Ubudlelwano kanye nemithelela yokubeka izinga ezigabeni ezihlukene
Engxoxweni elandelayo, izakhi zokukhiqiza ezizenzakalelayo ziyefana, okuhlanganisa isisindo sokumboza, izinga lokushisa, ingcindezi, njll. Ngenxa yokuthi zonke izakhi zizobangela izinguquko kuma-laminates wokugcina, sizobona lezi ziguquguqukayo njengezilungisiwe.
Ngenxa yokuthi i-adhesive-free adhesive ayinayo i-solvent ukuze ibe yisisekelo, indawo yokubeka izinga iwukusebenza kokunamathela kwayo.Uma sikhuluma nje, izoba msulwa, kodwa ingcina engancibilikiyo isenazo izici zayo.
Okokuqala, impahla yokulinganisa ye-SF enamathelayo inobudlelwane obuseduze ne-viscosity ye-adhesive ngokwayo.Nakuba i-viscosity inobudlelwane obuqondile nezinga lokushisa futhi ihluka ngokuphambene, okusho ukuthi i-viscosity ye-adhesive ye-SF izokwehla lapho izinga lokushisa likhuphuka.Bese kuthi ngaphansi kwezinga lokushisa legumbi, ama-viscosity we-SF anamathelayo anomehluko omkhulu ngokuya ngamamodeli anamathelayo e-SF ahlukene kanye nezakhiwo zomzimba.Kodwa-ke, ngaphansi kwezinga lokushisa elifanele lokusebenza kwemodeli eyodwa yokunamathisela ye-SF, umehluko webanga le-viscosity yawo awubonakali kakhulu.Ngakho-ke, umkhiqizo we-viscosity ophansi mhlawumbe awuwona ongcono uma uqhathanisa imodeli yokunamathela ye-SF ephezulu ye-viscosity ene-viscosity ephansi.Isibonelo, i-WD8262A/B ye-KANGDA NEW MATERIALS, ngaphansi kwezinga lokushisa layo lokusebenza (engaba ngu-45℃), i-viscosity yayo ingu-1100 mpa.s.Kodwa uma i-laminating i-PET.INK/ALU, ingafinyelela ukubukeka okuhle ngaphandle kwamachashazi ngesikhathi sokuqhakaza kokuqala.Njengesiphetho, akusho ukuthi i-viscosity ephansi ingaletha ukubukeka okuhle.Ukushintsha okunamandla kokunamathela kwe-SF yisikhathi esisheshayo, esidinga izakhi ezimbalwa ukuze kufinyelele umphumela omuhle.Phakathi naleso sikhathi, i-viscosity inesitezi esiphansi kakhulu.Isibonelo, ngaphansi kuka-80-90℃(i-Double component SF adhesive), i-viscosity inezinguquko ezincane nezinga lokushisa elikhuphukayo.
Ukulinganisa i-Frist ukuqhubeka ngokomzimba kwesimo sokunamathela esixubile.Ngemuva kwenqubo yokumboza, impahla yayo yokulinganisa iyancipha ngokuqhubekayo kanye nokusabela okusheshayo phakathi kwezingxenye ze-A&B kanye nokwehla kwezinga lokushisa.Ngokuvamile, izinga lokuqala lokunamathiswa kwe-SF lithathwa njengokulinganisa ngemva kokuvunguza kwe-laminating.Ngalesi sikhathi i-viscosity ye-adhesive izoba mkhulu kune-adhesive exutshwe kuma-rollers we-metering.
Ukulinganisa okunamathelayo okuluhlaza kusho indawo yokulingana yokunamathela ezigubhu ngaphambi kokuxutshwa.Lesi sakhiwo sokulinganisa asibambi iqhaza enqubweni yokukhishwa kwamafilimu noma ama-foil.
Impahla yokulinganisa okwesibili iwukuthi, ngemva kwenqubo yokwehliswa kwe-laminating futhi esigabeni sokuphulukisa, okunamathelayo kwe-SF kuya esigabeni sokusabela okusheshayo kwe-cross-link ngaphansi kwethonya lokushisa, futhi ukusebenza kokulinganisa kuyehla ukuze kunyamalale ngokuphelele.
3. Isiphetho
Ileveli yempahla yokunamathisela kwe-SF eluhlaza ngaphambi kokuxutshwa > indawo yokulevelisa okwesibili > impahla yokulevelisa yokunamathisela kwe-SF okuxubile kuma- metering roller > indawo yokuqala yokukala.Ngakho-ke, umkhuba wokushintsha i-viscosity wezinto zokunamathisela ze-SF empeleni kuyinqubo ekhulayo, ehluke ngokusobala kuma-SB anamathelayo.
Uma unemibuzo mayelana ne-SF laminating yokupakishwa okuguquguqukayo, sizimisele ukukusiza.
