Ifilimu yokushisa ephansi yangaphambi kokugqokakungase kube yizwi lokuqala olizwile.Ungase ube nokungabaza ngokushesha, ingabe umkhiqizo omusha?Ingabe izinga lokushisa eliphansi lokumboza ifilimu lifana nefilimu ebandayo ye-lamination?Uyini umehluko phakathiifilimu enamathelayo enezinga lokushisa eliphansikanye nefilimu enamathelayo enezinga eliphezulu lokushisa?
Vumela i-EKO iphendule imibuzo yakho ngamunye ngamunye.
Ifilimu ye-pre-coating yezinga lokushisa eliphansi ayiyona ifilimu ye-laminating ebandayo, futhi idonsele ukunakwa okukhulu emkhakheni wesicelo sefilimu ye-laminating ebandayo kusukela yethulwa.Ezinye izinto ezikwifilimu ebandayo ye-lamination zivame uku-oxidation ngokuhamba kwesikhathi, okuholela ekubeni phuzi komzimba wefilimu.Ikakhulukazi lapho kuvezwa ukukhanya kwelanga noma ukusetshenziswa isikhathi eside, inkinga ye-oxidation noma ukuphuzi ibaluleke kakhulu.Ifilimu ye-laminating ebandayo ingase futhi ibangele izinkinga ngokunamathela okungaphelele, njengama-bubbles emoyeni.Kodwa-ke, amafilimu angaphambi kokushisa okushisa aphansi anenzuzo enkulu ngokwekhwalithi namanani.
Inzuzo enkulu yamafilimu ahlanganisiwe anezinga lokushisa eliphansi izinga lokushisa eliphansi lenhlanganisela nezici eziphansi.Uma kuqhathaniswa namafilimu endabuko ahlanganiswe ngaphambili adinga amazinga okushisa aphezulu enhlanganisela, izinga lokushisa eliyinhlanganisela lamafilimu anezinga lokushisa eliphansi elimbozekile licishe libe ngu-85 ℃~90 ℃, kuyilapho amafilimu ajwayele ukumbozwa ngaphambili adinga izinga lokushisa eliyinhlanganisela elingu-100 ℃~120 ℃.Izinga lokushisa eliphansi eliyinhlanganisela lingavimbela ukuwohloka nokuncibilika kwezinto.Uma kuqhathaniswa namafilimu ajwayelekile angaphambi kokumboza, amafilimu angaphambi kokushisa aphansi afanele izinto ezibucayi lokushisa.Isibonelo, izinto zokuphrinta zokukhangisa ze-PP, izinto ze-PVC, iphepha le-thermosensitive, njll., kanye nezinkinga zokugoqa kanye ne-odge lapho kusetshenziswa amafilimu ajwayelekile angaphambi kokuhlanganisa amalebula okunamathela, ukusetshenziswa kwamafilimu anezinga lokushisa eliphansi lokumboza kugwema ukulimala noma ukuwohloka kwekhwalithi. okubangelwa amazinga okushisa aphezulu.
Okwesibili, ifilimu ye-pre-coating yezinga lokushisa eliphansi inokusebenza okuhle kakhulu kokunamathela.Ngenxa yokuthi ifilimu ye-pre-coating ephansi yokushisa ephansi ayilimazi ukwakheka kwezinto ngesikhathi sokuncibilika kwesendlalelo sokunamathela, ingafinyelela umphumela wokubopha ovikelekile.Ngaphezu kwalokho, inqubo yokubopha ifilimu ye-pre-coating yezinga eliphansi lokushisa ephansi iyashesha, ngaphandle kwesidingo sesikhathi eside sokulinda, okuthuthukisa ukusebenza kahle komsebenzi.
Ngaphezu kwalokho, ifilimu ye-pre-coating yezinga lokushisa eliphansi nayo inokusebenza kokuvikela imvelo.Uma kuqhathaniswa nokunamathiswa okuvamile kwendabuko,izinga lokushisa eliphansi pre enamathelaayikhiphi amagesi ayingozi ngesikhathi sokusetshenziswa.Ngamafuphi, ifilimu enamathelayo enezinga lokushisa eliphansi le-Hot-melt, enezinzuzo zokushisa okuphansi kwenhlanganisela, ukusebenza kwezindleko eziphezulu, ukuguquguquka okuhle nokuvikelwa kwemvelo, isibe yisinqumo esisha kumakhasimende amaningi anezidingo eziyinhlanganisela.Ezimbonini ezahlukahlukene, amafilimu okunamathela asezingeni eliphansi ashayela ukuthuthukiswa kwenqubo kanye nokwenza ngcono ukusebenza kahle.Khetha ifilimu enezinga lokushisa eliphansi ukuze uqinisekise ikhwalithi yemikhiqizo yakho.
