Ukwelashwa kwe-Intro to Surface of printing film Pure-easy

Ukwelashwa okungaphezulu kwefilimu yokuphrinta

Indawo ebushelelezi futhi engenazimbotshana yefilimu

Lapho ubuso befilimu bungelashwa, inki yokunyathelisa ayikwazi ukungena futhi ikhiqize ukunamathela.

Ngemuva kokwelashwa okungaphezulu, uyinki unganamathela ebusweni befilimu, futhi kwezinye izimo, ungandisa ukumelana nokungqubuzana, ama-solvents nezinye izakhiwo.

Izindlela eziyinhloko zokwelapha amafilimu okuphrinta i-surface coating kanye nokwelashwa kwe-corona.

Ukumboza ubuso

I-Surface coating iyi-coating esetshenziselwa ukuthuthukisa ukunamathela kokugcina nokunamathela kokuphrinta kwama-substrates amafilimu amancane.

Kunezinhlobo ezahlukene zamakhemikhali zokumbozwa kwangaphezulu, okuhlanganisa i-resin based, i-solvent based, amanzi, noma ukuphulukiswa kwe-UV. Izixazululo ze-acetone noma i-ethyl acetate zingasetshenziswa ukuhlola ukuba khona kwezingubo endaweni yezinto ezibonakalayo, futhi izindlela zokunyathelisa ze-rotogravure noma ze-lexicographer zingasetshenziswa ekucubunguleni.

Ukwelashwa kweCorona

Ukwelashwa kwe-Corona kuyinqubo yokudlulisa izinto phakathi kwama-electrode amabili ukukhulisa ukungezwani kwendawo.

Ukwelashwa kwe-Corona kusebenzisa imvamisa ephezulu namandla kagesi aphezulu ukuze kukhiqizwe i-corona esikhaleni esiphakathi kwesibambi sommese okhiphayo kanye nensingo, kwakha indawo enezinga lokushisa eliphansi le-plasma yokulungiswa kwendawo yefilimu yepulasitiki. Le ndlela ingaguqula ifilimu yepulasitiki isuke ekungeyona i-polar iye kwi-polar, ithuthukise ukungezwani kwendawo nokunamathela. Intengo yempahla yokwelapha i-corona iphansi futhi ilungele ukukhiqizwa okuqhubekayo, kodwa ukufana kokukhishwa kubi futhi kulula ukugqobhoza ifilimu, okuholela kumphumela wokwelapha olinganiselwe.

Ukusetshenziswa kwangempela kanye nomphumela

Ekusetshenzisweni okungokoqobo, ukwelashwa kwe-corona kusetshenziswa kakhulu ngenxa yobulula bayo kanye nomphumela omuhle wokwelapha. Iningi labakhiqizi bamafilimu e-BOPP basebenzisa ukwelashwa kwe-corona. Amandla okwelashwa kwe-corona anganqunywa ngokuhlola ukushuba kwendawo kwefilimu, futhi indlela yokuhlola evame ukusetshenziswa yindlela yokumboza.

Kafushane, ukumbozwa kwendawo kanye nokwelashwa kwe-corona izindlela ezimbili eziyinhloko zokwelapha amafilimu aphrintiwe, ngayinye inezici zayo kanye nobubanzi bokusetshenziswa. Ukukhetha indlela efanele kungathuthukisa umphumela welebula yokunamathisela ephrintayo kanye nekhwalithi yesitika sokunamathisela.
