Leli phepha ligxile ezintweni ezimbili zokunamathisela ezinamathelayo ezingenazo izinyibilikisi, lixoxa ngempahla yokulinganisa imikhiqizo engenazo izinyibilikisi.
1. Incazelo Eyisisekelo Yokulinganisa Impahla
Impahla yokulinganisa yikhono lokwemboza ukulinganisa ngokulinganayo nangokushelela ebusweni bezinto ezingaphansi komhlaba.
2. Ubudlelwano kanye Nemiphumela Yokulinganisa Ezigabeni Ezihlukene
Engxoxweni elandelayo, izakhi zokukhiqiza ziyafana ngokuzenzakalelayo, okuhlanganisa isisindo sokumboza, izinga lokushisa, ingcindezi, njll. Ngenxa yokuthi zonke izakhi zizobangela izinguquko kuma-laminate okugcina, sizobona lezi ziguquguquko njengezingaguquki.
Ngenxa yokuthi ingcina engenaso isinyibilikisi ayinaso isinyibilikisi esiyisisekelo, isici sokulinganisa ukusebenza kwengcina ngokwayo. Uma siqhathanisa, izoba msulwa kakhulu, kodwa ingcina engenaso isinyibilikisi isenezici zayo.
Okokuqala, isici sokulinganisa se-SF glue sihlobene kakhulu ne-viscosity ye-glue uqobo. Ngenkathi i-viscosity inobuhlobo obuqondile nezinga lokushisa futhi ihlukahluka ngokuphambene, okusho ukuthi i-viscosity ye-SF glue izoncipha lapho izinga lokushisa likhuphuka. Khona-ke ngaphansi kwezinga lokushisa legumbi, i-viscosity ye-SF glue adhesives eluhlaza inomehluko omkhulu ngokuya ngamamodeli ahlukene e-SF glue kanye nezakhiwo zomzimba. Kodwa-ke, ngaphansi kwezinga lokushisa elifanele lokusebenza kwemodeli eyodwa ye-SF glue, umehluko wobubanzi be-viscosity yayo awubonakali kakhulu. Ngakho-ke, umkhiqizo we-viscosity ephansi mhlawumbe awungcono uma uqhathanisa imodeli eyodwa ye-SF glue ephezulu ne-viscosity ephansi. Isibonelo, i-WD8262A/B ye-KANGDA NEW MATERIALS, ngaphansi kwezinga lokushisa layo lokusebenza (cishe ama-45℃), i-viscosity yayo ingu-1100 mpa.s. Kodwa uma i-laminate ye-PET.INK/ALU, ingafinyelela ukubukeka okuhle ngaphandle kwamachashazi ngesikhathi se-lamination yokuqala. Njengesiphetho, akusho ukuthi i-viscosity ephansi ingaletha ukubukeka okuhle. Ushintsho olunamandla lwe-SF glues luyisikhathi esisheshayo, esidinga izakhi eziningana ukuze sifinyelele umphumela omuhle. Okwamanje, i-viscosity inephansi eliphansi kakhulu. Isibonelo, ngaphansi kuka-80-90℃ (i-Double component SF adhesive), i-viscosity inezinguquko ezincane uma izinga lokushisa likhuphuka.
Ukulinganisa kwe-Frist kuwukuqhubeka ngokomzimba kwesimo sokunamathela okuxubile. Ngemva kwenqubo yokumboza, isici sayo sokulinganisa siyancipha kakhulu kanye nokusabela okusheshayo phakathi kwezingxenye ze-A&B kanye nokwehla kwezinga lokushisa. Ngokuvamile, ukulinganisa kokuqala kwe-SF glue kubhekwa njengokulinganisa ngemva kokugoqa kwe-laminating. Ngalesi sikhathi i-viscosity ye-glue izokhula kakhulu kune-glue exubile kuma-metering rollers.
Ukulinganisa i-adhesive eluhlaza kusho i-adhesive esezingeni eliphezulu kuma-drums ngaphambi kokuba ixutshwe. Le mpahla yokulinganisa ayihlanganyeli enkambisweni yokunamathisela amafilimu noma ama-foil.
Isici sesibili sokulinganisa ukuthi, ngemva kwenqubo yokunamathisela kanye nesigaba sokulungisa, i-SF glue ingena esigabeni sokusabela okusheshayo kwe-cross-link ngaphansi kwethonya lokushisa, futhi ukusebenza kokulinganisa kwehla kuze kube yilapho kunyamalala ngokuphelele.
3. Isiphetho
Impahla yokulinganisa ye-glue ye-SF eluhlaza ngaphambi kokuxutshwa > impahla yokulinganisa yesibili > impahla yokulinganisa ye-glue ye-SF exutshwe kuma-rollers okulinganisa > impahla yokulinganisa yokuqala. Ngakho-ke, ukuthambekela kokushintsha kwe-viscosity ye-glue ye-SF empeleni kuyinqubo ekhulayo, ehluke ngokusobala kuma-glue e-SB.
Uma unemibuzo mayelana ne-SF laminating yokupakisha okuguquguqukayo, sizimisele ukukusiza.
