Ubuchwepheshe bePhepha Elinanyathiselwe le-Paperjoy Deciphers Core: Ukwelashwa kwe-Corona Kuyithuthukisa Kanjani I-PE Coating Adhesion?
Ekukhiqizweni kwe iphepha lokupakisha ukudla elinoqweqwe oluthambile, Ukunamathela kwe-PE coating kunquma ngqo ukuqina nokuphepha komkhiqizo, futhi kuyinkomba eyinhloko yokulinganisa Iphepha Eligcotshwe ikhwalithi.I-PaperjoyI-Paper (Nanning Paperjoy Paper Co., Ltd.) ibilokhu ihlanganyela enkonzweni yokuhweba kwamanye amazwe yokupakisha ukudla okune-laminated paper products. Namuhla, ichaza ubuchwepheshe obuyinhloko be-pre-lamination — ukwelashwa kwe-corona, iveza ukuthi ithuthukisa kanjani ukunamathela kwe-PE coating futhi igweme amaphutha omkhiqizo.
Ukwelashwa kwe-corona kuyindlela eyinhloko yokulungiselela ukwelashwa iphepha elinolaminethiukukhiqizwa, ngesimiso esicacile: Kusetshenziswa ugesi ovama kakhulu nowamandla aphezulu (i-voltage 5000-15000V/㎡) phakathi kwe-electrode yokukhipha kanye ne-roller yokwelapha i-corona ezinikele (eyenziwe ngerabha ye-silicone noma i-ceramic, enokumelana nokushisa okuphezulu, ukumelana ne-ozone kanye nokushisa okuqinile). Lapho i-voltage iphula ukumelana kwe-ionization kwegebe lomoya elingu-1-2mm, umoya uyafakwa kwi-ionization ukuze ukhiqize inani elikhulu le-ozone. I-Ozone ifaka i-oxidize kuma-molecule angaphezulu epulasitiki ukuze akhe ama-carbonyl compounds nama-peroxide. Ngesikhathi esifanayo, i-plasma ithinta ubuso befilimu, iphule amaketanga e-polymer futhi ibangele ukusabela kwe-oxidative cross-linking – ekugcineni ithuthukisa kakhulu ukungezwani kobuso befilimu futhi ithuthukise ngokuyisisekelo ukunamathela kwezinqubo ezilandelayo zokuphrinta, ukunamathela kanye ne-lamination.
Ithimba lobuchwepheshe le-Paperjoy liveza ukuthi ukusetshenziswa okungokoqobo kokwelashwa kwe-corona kudinga ukuqonda amaphuzu amabili ayinhloko:
①I-voltage namandla azinzile: I-voltage kumele igcinwe njalo ngaphezu kwe-6KV kanye namandla angaphansi kwe-6KW. Ikakhulukazi enqubweni ye-extrusion lamination, izinto eziyisisekelo kumele ziphathwe nge-corona yendawo ephakathi. I-voltage enganele noma ukwelashwa okunganele kuzoholela ngqo ekucindezelekeni okunganele kwendawo okuyisisekelo, okubangela amaphutha njengokuqhekeka kwe-PE coating kanye ne-delamination.
②Umphumela wokuhlanza ubuso: Ukwelashwa kwe-corona kungasusa uwoyela, umswakama kanye nokungcola ngasikhathi sinye ebusweni befilimu, kususe izithiyo zezinqubo zokunamathela ezilandelayo, kuthuthukiswe ukunamathela kweyinki yokuphrinta futhi kuncishiswe izinga lokukhubazeka kwemikhiqizo eqediwe.
Ngokusekelwe ocwaningweni olujulile ngobuchwepheshe bephepha elihlanganisiwe, i-Paperjoy yakhe uhlelo lokuguquguquka kwepharamitha yokwelashwa kwe-corona oluvuthiwe kanye nezindinganiso zokusebenza ezisebenzayo. Inganikeza ukwesekwa kobuchwepheshe okwenziwe ngokwezifiso kwamabhizinisi okupakisha ukudla emhlabeni wonke ngokuya ngezinto eziyisisekelo ezahlukene, izinto zokusetshenziswa ze-PE kanye nezidingo zomkhiqizo, kufaka phakathi ukwenziwa ngcono kwepharamitha yokwelashwa kwe-corona, iziphakamiso zokuguquguquka kwezinto eziyisisekelo kanye nezinhlelo zokuthuthukisa ikhwalithi yenqubo ehlanganisiwe, ukuxazulula ngokunembile izinkinga zokukhiqiza zamakhasimende. Ukuze uthole izixazululo zobuchwepheshe ezikhethekile noma ukuhlolwa kwesampula, sicela uvakashele iwebhusayithi esemthethweni ye-Paperjoy ku- www.paperjoypaper.comukuze kuboniswene.
