Ngokuthuthuka kwesayensi nobuchwepheshe, izinto eziningi ezintsha ezisebenzayo kanye nemikhiqizo ziyafika emakethe. I-NDC, ihambisana nezidingo zokumaketha, ibambisene nochwepheshe bezokwelapha futhi yathuthukisa imishini ehlukahlukene ekhethekile embonini yezokwelapha. Ikakhulukazi ngesikhathi esibucayi lapho i-COVID-19 ibhubhisa umhlaba eminyakeni emithathu edlule, i-NDC inikeza imishini eqinile ukuqinisekisa abakhiqizi abakhiqiza izinto zokuzivikela embonini yezokwelapha. Sithole futhi ukuqashelwa komphakathi okuphezulu kanye nendumiso evela emabhizinisini amaningi ezokwelapha kanye nohulumeni.
Inqubo yobuchwepheshe bokumboza i-NDC ingahlukaniswa ngezindlela ezintathu, sikhetha ubuchwepheshe bokumboza obuhle kakhulu ngokuya ngezidingo zomsebenzi womkhiqizo kanye nezici zokunamathela.
1. Ubuchwepheshe Bokumboza I-Gravure Anilox Roller Transfer
I-Gravure Anilox Roller coating iyindlela yendabuko yokumboza, njengobuchwepheshe bokuphrinta i-gravure. I-hot melt glue ifakwa endwangu engalukiwe nge-anilox roller eqoshiwe ene-slot scraper. Kuyindlela yokumboza engenakuphindwa yobuchwepheshe bokumboza obunamaphethini, obungafeza isidingo sokuphefumula.
Kodwa-ke, uma ufuna ukulungisa inani le-glue coating, udinga ukushintsha i-coating roller ngama-anilox rollers ahlukene okujula nokuma.
Indlela yokumboza nge-Anilox roller ifanelekela izinhlobo eziningi zeglue, kufaka phakathi i-PUR adhesive, okulula ukuyihlanza. Ezinye izinamathiseli ezishisayo ezincibilikayo zishintshwa kalula yi-carbon mode evulekile yokushisa.
2. I-Spray (ingcina yokufutha engathintani) Ubuchwepheshe Bokumboza
Ukufutha nge-spray kuyindlela ejwayelekile yokufutha. Kunezinhlobo ezimbili zezibhamu zokufutha: isibhamu esincane sokufutha esijikelezayo kanye nesibhamu sokufutha nge-fiber.
Inzuzo ukuthi ingafuthwa ngqo ezintweni ezingamelani nokushisa okuphezulu, futhi izinto zinomoya omuhle wokungena, futhi kulula ukulungisa isisindo sokufutha nobubanzi. Lena inzuzo yesibhamu sokufutha. Inkinga ukuthi umlomo uzovinjelwa ngokungenakugwenywa futhi akulula ukuwuhlanza, futhi enkambisweni yokukhiqiza kuzoba nezimpawu zokuvuza kokufutha kanye nokuwa kweglue, okuzobangela amaphutha kumkhiqizo. Ukufutha akukhuthazwa ngeglue eshisayo ye-PUR.
3. Ubuchwepheshe Bokumboza Okuphefumulayo Be-Slot Die
I-contact slot die airthable coating iyindlela ethuthukisiwe yokumboza engahlangabezana nenani eliphansi lokumboza ngeglue kuya ekusetshenzisweni kwenani eliphezulu lokumboza. Ukufana okuhle kokumboza, ukuba yisicaba okuhle kokumboza, isisindo seglue esilula ukusilungisa kanye nobubanzi bokumboza. Isetshenziswa kabanzi emigqeni yokukhiqizwa kokumboza kanye nokumboza kwezinto zokugqoka ezihlukanisayo/izinto zeteyipu yezokwelapha ezizinamathelayo, izinto zokunamathisela zokugqoka zezokwelapha izinto zeplasta yezokwelapha njll.
I-NDC isifinyelele ububanzi bomshini obungu-3600mm kumakhasimende. Isivinini sokumboza i-Anilox Roller singu-200m/min, isivinini sokumboza esingathintani nesifutho singu-300m/min kanye nesivinini sokumboza esithintana nokuphefumula singu-400m/min.
Ubuchwepheshe budinga imvula, ulwazi ludinga ukuqongelelwa, amandla okukhiqiza adinga ukutshalwa kwezimali.
I-NDC ihlala inamathela emgomweni wayo wokukhuthaza ukuthuthukiswa kokusetshenziswa kobuchwepheshe bokufafaza nge-hot melt glue kanye nobuchwepheshe bokumboza. Sizinikele ekuhlinzekeni ngemishini ekhethekile kanye nezixazululo zobuchwepheshe zokusetshenziswa kwe-hot melt glue emikhakheni ehlukene.
