Amalebula azinamathelayo ayizinhlobonhlobo ezibalulekile zokuphrinta ezisetshenziswa kakhulu ekupakishweni kwempahla, izinto zokuhamba, kanye nokuhlonza okuhlukahlukene. Ngokuphrinta ilebula yokuzinamathisela, i-lamination iyisixhumanisi esibucayi kakhulu. Ingavikela indawo yelebula, ukuthuthukisa ukuqina, futhi uthuthukise ubuhle bobuhle, ngalokho kuthuthukisa impilo yesevisi kanye nekhwalithi yamalebula azinamathelayo. Lesi sihloko sizokwethula inqubo ye-lamination kanye nendlela yamalebula wokuzinamathisela ngemva kokuphrinta, okuhloswe ngayo ukusiza abafundi baqonde izindlela ezehlukene zokuzalanisa, amaphuzu ezobuchwepheshe, nokukhetha impahla, kanye nendlela yokuphatha kahle inqubo ye-lamination efanele ukuqinisekisa ikhwalithi nokuthembeka.
Iqhaza Lelebula Lamination
Izimbobo zamalebula zisetshenziselwa ukuvikela amalebula ekulimaleni kwemvelo njengamanzi, Imisebe ye-UV, ukuhuzuka, njll. Ngokungeza ifilimu yokuvikela ecacile ebusweni belebula, ungakwazi ukunweba impilo yelebula futhi ugcine ukubonakala kwayo kucacile. Ukwakhiwa kwamalebula kungaphinda kuthuthukise ukuqina kwelebula futhi kuvimbele izithombe noma umbhalo okumalebula ukuthi ungafiphali ngokuhamba kwesikhathi. Ama-laminates nawo ahlinzeka ngokuvikeleka okwengeziwe, ukuqinisekisa ukuthi amalebula awonakele ngesikhathi sokuthunyelwa nokugcinwa. Zonke lezi zinzuzo zingathuthukisa ulwazi lwekhasimende, ngaleyo ndlela kuthuthukisa ukuqwashisa komkhiqizo.
I-Laminated Material
I-lamination of self-adhesive amalebula ngokuvamile isebenzisa izinto ezilandelayo:
Ifilimu yePolyester (I-PET): Le nto iqinile futhi ayikwazi ukumelana namanzi, futhi inikeza ukuphrinta kwekhwalithi ephezulu kwezithombe nombhalo.
Ifilimu ye-polypropylene (PP): Ilula futhi isobala kakhulu, le nto ihlinzeka ngesendlalelo esivikelayo esiqinile. Ifilimu ye-PP ehlanganisiwe ebonakala ngokugcwele iyinto esetshenziswa kakhulu. Isizathu siwukuthi i-PP inenani eliphansi futhi ihlala isikhathi eside kunezinye izinto ezimbalwa.
Ifilimu ye-Polyvinyl Chloride (I-PVC): Lokhu okubalulekile kungokonga, kodwa ayihambisani neze nemvelo kunezinto ze-PET noma ze-PP.
Ifilimu ye-polyethylene (I-PE): Le nto ithambile futhi ilungele ukulebula endaweni egobile noma engajwayelekile.
Ngenxa yezidingo zezindleko, ukumbozwa kwezinto zokwenziwa kwephepha ngokuyisisekelo kuthathelwa indawo ubuchwepheshe be-glazing. Embonini yamalebula, lapho i-varnish ingakwazi ukuhlangabezana nokukhanya kanye nezidingo ze-matte, i-lamination iyindlela eqondile kakhulu. Singakhetha izinto ezifanele zokucwala ngokwezimo ezihlukene zohlelo lokusebenza ukuze siqinisekise ukuthi ilebula ithola ukuvikeleka okungcono kakhulu nokuqina..
Laminating Izindlela
Izindlela zokubeka ilebula zivame ukuhlukaniswa nge-lamination yeshidi kanye ne-roll material lamination. Iphepha elifakwe ngeshidi li-laminated emshinini we-laminating, futhi impahla yomqulu i-laminated esiteshini se-laminating yomshini welebula noma emshinini okhethekile wokugcoba. Izindlela ezimbili zokumboza zichazwe ngezansi:
- I-Laminated Eshidi
I-Sheetfed lamination ihlanganisa ukubeka amalebula eshidini lezinto zokuthambisa nokusebenzisa ukushisa nokucindezela ukuze kuhlanganiswe i-lamination kanye nokulebula ndawonye.. Le ndlela ifaneleka ezimweni lapho amalebula ngamanye adinga ukufakwa laminated, njengalapho amalebula enosayizi abahlukene noma ukuphathwa okukhethekile kuyadingeka kumalebula. I-lamination ye-Sheetfed ingenziwa kusetshenziswa ama-laminator okwenziwa ngesandla noma othomathikhi.
Kunezindlela ezimbili zokufaka amalebula okuzinamathelisa afakwe ngeshidi, okungukuthi osheshayo enamathela lamination kanye pre-enamathela ifilimu lamination.
1)Inqubo yokuhlanganisa yokuhlanganisa i-coating esheshayo imi kanje: okokuqala, i-adhesive iboshwe ebusweni befilimu ye-BOPP roll, futhi i-solvent in the adhesive is volatilized ngokusebenzisa idivayisi yokomisa, bese kuthi iphepha leshidi lihlanganiswe nefilimu ye-roll esiteshini sokuhlanganisa. Inhlanganisela, laba ababili baba munye ngaphansi kwe-extrusion ye-roller eshisayo, futhi inqubo yokumboza ifilimu isiqediwe.
2)Inhlanganisela yefilimu ehlanganiswe ngaphambili isho ukumboza kuqala ungqimba lwe-adhesive noma into e-laminating ebusweni befilimu eyinhlanganisela.. Kunezinhlobo ezimbili zamafilimu, uhlobo olunamathelayo olushisayo oluncibilikayo kanye nohlobo oluzwela ukucindezela. Umshini we-laminating ufakwe i-roller embossing eshisayo, futhi ifilimu ehlanganiswe ngaphambili ixhumene nephepha ngesikhathi sokucwenga. Ngaphansi kwesenzo se-roller yokucindezela okushisayo, ingcina iyancibilika, ukuze ifilimu nephepha kuhlanganiswe kube yinto eyodwa. Uma usebenzisa ifilimu eyinhlanganisela ezwela ukucindezela, ungavala ukunikezwa kwamandla okushisa futhi uthembele kuphela ekucindezelweni kwenhlanganisela.
- Roll Material Lamination
I-Roll material lamination iwukuphrinta ifilimu lezinto ezibonakalayo bese ulebula ndawonye, bese uwadlulisa ndawonye ngomshini wokulahla ukushisa nokwelashwa kwengcindezi. Le ndlela ilungele ukukhiqizwa kwenani elikhulu lamalebula, okungathuthukisa ukusebenza kahle kokukhiqiza nokunciphisa izindleko. Ukufakwa kwezinto zewebhu kungenziwa ngeqoqo noma ukukhiqizwa okuqhubekayo.
I-Web lamination ivame ukuhlukaniswa ngezinhlobo ezimbili: ifilimu eyinhlanganisela yephepha eliphansi eyinhlanganisela yefilimu eyinhlanganisela yephepha elingenalutho eliyinhlanganisela yefilimu.
1)I-Backing paper composite film lamination ibhekisela ekuhlanganiseni ungqimba lwephepha elisekelayo ngaphambili noma ngemuva kwephepha lokugoqa., bese umboza ungqimba lwe-adhesive noma i-laminating ephepheni elisekelayo, bese unamathisela ilebula kuyo. I-Backed paper composite film lamination iyindlela yendabuko yokubeka, esithathelwe indawo yinqubo yokusebenzisa ifilimu eyinhlanganisela yephepha elingenalutho eminyakeni yamuva nje.
2)Isimiso se-laminating sefilimu eyinhlanganisela ngaphandle kwephepha eliphansi ngokuyisisekelo sifana naleyo yefilimu eyinhlanganisela enephepha eliphansi.. Ifilimu elisekelayo lephepha livuselelwa ngobushelelezi bobuso (ukungezwani kwendawo) wempahla yayo esikhundleni sephepha elisekelayo. Ngemuva kokuthi i-adhesive ihlanganiswe phezulu, ingacwecwa ngaphandle kokushiya noma yimiphi imikhondo yeglue. Izinto ezisetshenziselwa ifilimu yephepha elingenasiphelo ngokuvamile ifilimu ye-BOPP enokungezwani okuphansi. Izindleko ze-lamination yefilimu yephepha elingenalutho ziphansi, futhi yiyona nto esetshenziswa kabanzi kakhulu yokulambisa okwamanje. Inzuzo yenhlanganisela yefilimu eyinhlanganisela yephepha engapheli ukuthi ingathuthukisa ukusebenza kahle kokukhiqiza, ukunciphisa udoti ohlelweni lokukhiqiza, futhi ngesikhathi esifanayo ngcono izinga lomkhiqizo.
Kunjalo, kungakhathaliseki ukuthi iyiphi indlela ye-lamination esetshenziswayo, ungqimba oluvikelayo lungakhiwa ebusweni belebula ukuvikela ilebula ekulimaleni kwemvelo.
Ngokuphrinta ilebula yokuzinamathisela, lamination kuyisinyathelo esibaluleke kakhulu, ngoba ingenza ilebula ibe yinhle kakhulu, isikhathi eside, kanye nezimo. Indlela efanele ye-lamination kanye nokukhethwa kwezinto ezibonakalayo kungaqinisekisa ikhwalithi kanye nempilo yesevisi yamalebula okuzibamba. Ngakho-ke, abakhiqizi bokunyathelisa kanye nabasebenzisi kufanele banake ukukhethwa kwezindlela ezifanele zokucwenga kanye nezinto zokwakha, futhi ulawule ikhwalithi ukuze uqinisekise ikhwalithi yokugcina yamalebula azinamathelayo.
