I-Roll Yokupakisha Ukudla Ifilimu Yokupakisha Okuzenzakalelayo Yomshini Wokupakisha wePlastiki

Ifilimu eyinhlanganisela eyenziwe ngezingqimba ezimbili noma ngaphezulu kufanele ihlukaniseke njengefilimu eyodwa. Lokhu kuhilela okungaphezu nje kokunamathela phakathi kwamafilimu amabili. Okunye okuhlobene nefilimu kayinki. Izinamathiselo ziyimikhiqizo yokwenziwa Izinto eziningi ezinamathelayo ziyizingxenye ezimbili ze-polyurethane (PU) zokunamathisela. Ukusabela kwamakhemikhali kwenqubo yokumba kuphulukisa ingcina. I-adhesive ebusweni be-substrate ngokuyinhloko inqubo yomzimba futhi ingxenye encane kuphela inqubo yamakhemikhali. Ngalesi sikhathi, izingxenye ze-adhesive ziboshwe kanye nezingxenye zefilimu yepulasitiki futhi ziqhubeke ziphulukiswa.
Uma ifilimu eyinhlanganisela isivele iphrintiwe ngesikhathi senqubo yokuhlanganisa i-adhesive noyinki kufanele kuhlangabezane nezidingo ezengeziwe. Imfuneko eyisisekelo kakhulu ukuthi ungqimba lwangaphakathi kufanele lube nokushesha kokunamathela okuhle kanye nokoma ngaphambi kokuba i-lamination. Lokhu kusho ukuthi azikho izinsalela ze-solvent ezivunyelwe kulayini ophrintiwe. Kodwa i-solvent noma utshwala ngokuvamile bushiywa ku-binder kayinki. Ngenxa yalesi sizathu, izakhiwo ze-adhesive kufanele zikwazi ukubopha kuma-radicals mahhala (amaqembu -OH). Uma kungenjalo, i-adhesive kanye ne-ejenti elaphayo zizosabela ngokwazo futhi zilahlekelwe izakhiwo zazo zangempela.
Phakathi kwezinamatheliso, izinamatheliso ezisekelwe ku-solvent zihlukaniswa nezinamatheliso ezingenayo i-solvent njengezinamathiseli ze-UV. Ingxube ye-solvent-based drill idinga umhubhe wokumisa ukuze ushise isincibilikisi. Lapho kusetshenziswa izinto ezinamathelayo ze-UV, ukukhanya kwe-UV kuhamba ngefilimu eyinhlanganisela kuye kokunamathelayo ukuze kwenziwe i-polymerize into enamathelayo ndawonye.
1. Inhlanganisela eyomile
Ibhekisela endleleni lapho okunamathelayo kuhlanganiswe khona esimweni esomile. Okokuqala, i-adhesive ifakwe ku-substrate. Ngemva kokumisa emhubheni wokomisa, zonke izincibilikisi ku-adhesive zomiswa. Inqubo yokuncibilikisa i-adhesive, ukuhlanganisa enye i-substrate kuyo, ukupholisa, nokuphulukisa ukukhiqiza into eyinhlanganisela enezakhiwo ezinhle.
2. Inhlanganisela ye-Extrusion
Kwaziwa nangokuthi i-casting compounding, okungenye yezindlela zokukhiqiza eziyinhloko zokupakisha okuvumelana nezimo. Incibilikisa ama-thermoplastics afana ne-polyethylene ne-polypropylene emshinini ohlanganisa i-extrusion, futhi igeleza ngokufanayo ngefilimu encane evela ekhanda eliyisicaba, futhi ihlale imbozwe phezu kwesisekelo, ifilimu eyinhlanganisela yezendlalelo ezimbili noma ngaphezulu yenziwa ngokucindezela nge. i-roller yokucindezela nokupholisa nge-roller yokupholisa.
I-Extrusion lamination inezinzuzo zejubane lokukhiqiza elisheshayo, inqubo elula yokukhiqiza, indawo yokukhiqiza ehlanzekile, ukusebenza kahle kokukhiqiza okuphezulu, ukusebenza okulula, izindleko eziphansi, futhi akukho zinsalela ze-solvent. indawo ebalulekile.
