Inqubo ye-laminating kanye nenqubo yokucwebezela kokubili kungokwesigaba se-post-printing surface finishing processing yendaba ephrintiwe.Imisebenzi yalokhu kokubili ifana kakhulu, futhi zombili zingadlala indima ethile ekuhlobiseni nasekuvikeleni ingaphezulu lendaba ephrintiwe, kodwa kukhona umehluko phakathi kwalokhu okubili:
Ukuqedwa kobuso
Ukuqedwa kobuso ukwenza ukucubungula okufanele ebusweni bendaba ephrintiwe ukuze kuthuthukiswe ukumelana nokukhanya, ukumelana kwamanzi, ukumelana nokushisa, ukumelana nokugoqa, ukumelana nokugqoka kanye nokumelana namakhemikhali ento ephrintiwe;ukwandisa isicwebezelisi nomqondo wobuciko wendaba ephrintiwe;futhi uvikele indaba ebhaliwe.Nomsebenzi wokwenza izinto ezinyathelisiwe zibe zinhle nokwandisa inani lezinto ezinyathelisiwe.Izindlela ezijwayelekile zokuguqula indawo yezinto eziphrintiwe zifaka ukucwebezela, ukucwala, ukufohloza, ukusika, ukusika noma okunye ukucutshungulwa.
01 incazelo
I-Laminationinqubo yokunyathelisa ngemva kokunyathelisa lapho ifilimu yepulasitiki ehlanganiswe nge-adhesive ihlanganiswe ebusweni bendaba ephrintiwe.Ngemuva kokwelashwa kokushisa nokucindezela, indaba ephrintiwe kanye nefilimu yepulasitiki kuhlanganiswe eduze ukuze kube umkhiqizo ohlanganisiwe wephepha-plastiki.Inqubo ye-laminating ingeyenqubo ye-paper-plastic composite in the composite process futhi iyinhlanganisela eyomile.
Ukucwebezela kuyinqubo lapho kusetshenziswa ungqimba lukapende okhanyayo ongenambala (noma lufuthwe noma luphrintwe) phezu kwento ephrintiwe.Ngemuva kokulinganisa nokomisa (i-calendering), ungqimba olukhanyayo oluncane oluncane futhi olusobala lwakhiwa ebusweni bendaba ephrintiwe.Inqubo iwukumboza (okuvame ukwaziwa ngokuthi Inqubo yokufaka ivarnish (okuhlanganisa i-resin eyenza ifilimu, i-solvent kanye nezithasiselo) ebusweni bento ephrintiwe ukuze ilinganiswe futhi yomiswe.
02 Umsebenzi nencazelo
Ngemuva kokuthi ingaphezulu lendaba ephrintiwe limbozwe ungqimba lwefilimu yepulasitiki (i-coating) noma imbozwe ngopende ocwebezelayo (glazing), indaba ephrintiwe ingenziwa ukuze ibe nemisebenzi yokumelana nokungqubuzana, umswakama-umswakama, amanzi kanye anti-fouling, njll, engavikeli nje indaba ephrintiwe, kodwa futhi ivikela indaba ephrintiwe.Ukunweba impilo yayo yesevisi, iphinde ithuthukise ukugqama kwendawo ephrintiwe, ithuthukise inani layo lokuhlobisa, yenza ihluzo eziphrintiwe nombhalo ugqame ngombala, futhi ibe nomthelela obonakalayo oqinile, ngaleyo ndlela ithuthukise ikhwalithi yomkhiqizo futhi ikhulise inani elengeziwe.Isibonelo, i-lamination yekhava yencwadi, i-surface glazing yamabhokisi okupakisha ezimonyo, njll.
Ngakho-ke, i-laminating kanye ne-glazing ingenye yezobuchwepheshe obuyinhloko bokucubungula kokuqeda ukuphrinta kwendawo yokuqeda indaba ephrintiwe.Abakwazi kuphela "ukukhanyisa" ubuso bendaba ephrintiwe futhi bahehe ukunaka kwabathengi, kodwa futhi bavikele indaba ephrintiwe futhi bathuthukise ukusebenza kwayo.Manje asetshenziswa kabanzi.Ilungele ukuhlobisa kwangaphandle kwezincwadi, ama-periodical, ama-albhamu ezithombe, imibhalo ehlukahlukene, izincwajana zokukhangisa kanye nomhlobiso ongaphezulu wemikhiqizo ehlukahlukene yokupakisha iphepha.
03 Inqubo ihlukile
Inqubo yokumboza ifilimu Inqubo yokumboza ifilimu ingahlukaniswa ngobuchwepheshe befilimu yokuhlanganisa osheshayo kanye nobuchwepheshe befilimu bokumboza ngaphambili ngokwezinto zokusetshenziswa ezahlukene kanye nemishini esetshenziswayo.
1) Iifilimu yokugqoka cubungula kuqala isebenzisa idivaysi yokugqoka i-roller ukuze igqoke ngokulinganayo ingcina ebusweni befilimu yepulasitiki.Ngemva kokudlula kudivayisi yokomisa, i-solvent in the adhesive is evaporated, bese indaba ephrintiwe idonselwa kudivayisi yokucindezela okushisayo.Emshinini, iifilimu yepulasitikifuthi izinto eziphrintiwe zicindezelwa ndawonye ukuze kuqedelwe ukufakwa kwe-lamination nokuhlehliswa, bese zigcinwa ukuze zibunjwe futhi zinqunywe.Le ndlela okwamanje isetshenziswa kakhulu eChina.Ngokombono wezinto zokunamathisela ezisetshenziswe efilimu yokugqoka, ingahlukaniswa ifilimu yokunamathisela esekelwe ku-solvent kanye nefilimu yokunamathisela emanzini.
2) Ifilimu yokugqoka kwangaphambili Inqubo yefilimu yokumboza ngaphambili ingeyabakhiqizi abangochwepheshe ukuthi bafake izinto zokunamathisela kusengaphambili ngokomthamo nangokulinganayo kumafilimu epulasitiki, zome, zihlehlise emuva, futhi ziwapakishe emikhiqizweni ethengiswayo, bese izinkampani ezicubungulayo zisebenzisa okokunamathela okunganamatheli kuwo.Ukucindezela okushisayo kwenziwa emishinini yokulambisa yedivayisi ukuze kuqedelwe inqubo yokufaka i-laminating yendaba ephrintiwe.Inqubo yefilimu yangaphambi kokumboza yenza lula kakhulu inqubo yokumboza ngoba imishini yokumboza ayidingi i-adhesive heat and drying system, futhi ilula kakhulu ukusebenza.Ngesikhathi esifanayo, akukho ukuguquguquka kwe-solvent futhi akukho ukungcoliswa kwemvelo, okuthuthukisa indawo yokusebenza;okubaluleke kakhulu, it Ukuvela kokwehluleka kwekhwalithi yokumboza njengamabhamuza kanye ne-delamination kugwenywa ngokuphelele.Ukungafihli kwemikhiqizo eboshwe kuphezulu kakhulu.Uma kuqhathaniswa nenqubo yokwemboza evamile, inamathuba amaningi okufaka isicelo.
1) I-solvent-based glazing Ukucwebezela okusekelwe ekuncibilikeni kubhekisela kunqubo ecwebezelayo esebenzisa i-benzene, esters notshwala njengezincibilikisi kanye nenhlaka ye-thermoplastic njengenhlaka eyakha ifilimu.Ngesikhathi se-glazing, i-solvent iyahwamuka bese i-resin ipholisa noma i-Cross-linking reaction yakha ifilimu.Ibonakala ngokutshalwa kwezimali kwemishini encane kanye nezindleko eziphansi, kodwa ukuvuthwa kwe-solvent kanye nezinsalela endabeni ephrintiwe kuzodala ukungcoliswa kwemvelo futhi kube yingozi emzimbeni womuntu.
2) I-glazing esekelwe emanzini Ukucwebezelisa okusekelwe emanzini kuyindlela ecwebezelayo esebenzisa inhlaka encibilika emanzini noma izinhlobo ezahlukene zama-resin ahlakazeke ngamanzi njengezinto ezenza ifilimu.Upende ocwebezelayo osuselwe emanzini usebenzisa amanzi njengesincibilikisi, futhi ayikho into eguquguqukayo ye-organic solvent phakathi nenqubo yokumboza nokomisa.Isici siwukuthi inqubo yokucwenga ayinalo iphunga elicasulayo, akukho ukungcola kwemvelo, futhi ayinabungozi emzimbeni womuntu.Isetshenziswa kabanzi ekufakweni kukagwayi, imithi, ukudla, izimonyo nezinye izinto.
3) Ukukhanya kwe-UV I-UV glazing iyimisebe ye-ultraviolet eyomile ecwebezelayo.Isebenzisa imisebe ye-ultraviolet ukuze ikhanyise uwoyela ocwebezelayo ukuze iqalise ngokushesha ukusabela kwe-photochemical yamafutha acwebezelayo ukuze kwakheke uqweqwe olukhanyayo olunesakhiwo samakhemikhali senethiwekhi ebusweni bendaba ephrintiwe.Inqubo yokwelapha ecwebezelayo iyafana nenqubo yokomisa kayinki we-UV.Ibonakala nge-gloss enhle, ukumelana nokushisa okuqinile nokumelana nokugqoka, ukomisa okusheshayo, ukuphepha nokuvikelwa kwemvelo.Inamathuba abanzi okuthuthukiswa kwezimakethe.Njenge-glazing esekwe emanzini, isetshenziswa kakhulu emithini, ekudleni, njll. Ukupakishwa komkhiqizo ensimini.
