Ukuphrinta kwe-film flexo akukavuthwa kakhulu kubakhiqizi bokupakisha abaguquguqukayo basekhaya. Kodwa ngokuhamba kwesikhathi, kunendawo enkulu yokuthuthukiswa kobuchwepheshe bokuphrinta kwe-flexo esikhathini esizayo. Lesi sihloko sifingqa izinkinga eziyishumi nambili ezivamile kanye nezixazululo ekuphrinteni kwe-film flexo. ukuze kubhekwe. Umshini wokuphrinta wewebhu Umshini wokuphrinta we-Flexo Umshini wokwenza izikhwama ze-envelope Umshini wokuphrinta iphepha lezokwelapha Umshini wokusika ama-roll

1. Ukunyatheliswa kwefilimu akunaso isiqiniseko sokunamathela esibi, futhi akumelani nokuhlikihla nokuhlikihla

Izizathu kanye neziphakamiso zokwelapha: Umshini wokunyathelisa iwebhu, umshini wokunyathelisa we-flexo, umshini wokwenza izikhwama zemvilophu, umshini wokunyathelisa iphepha lezokwelapha, umshini wokusika imiqulu

(1) Ifilimu ye-PE noma ye-PP ayinayo indlela yokwelapha ubuso noma umphumela wokwelapha ubuso awulungile, futhi ukucindezeleka kobuso befilimu kungaphansi kuka-(3.6 ~ 3.8) × 10-2N/m. Sebenzisa uketshezi lokuhlola ukucindezeleka kobuso ukuthola ukucindezeleka kobuso befilimu. Uma yehluleka ukuhlangabezana nezidingo, kufanele iphinde iphathwe ubuso.

(1) Kukhona ukungcola kuyinki, uyinki kufanele uhlungwe noma ushintshwe ngomusha.

(2) Uyinki ukhuluphele, futhi inani elithile lonciphile lingangezwa ukuze kulungiswe ukujiya kweyinki kube yinani elifanele imizuzwana engama-25 kuya kwengama-35.

(3) Uyinki woma ngokushesha kakhulu. Faka inani elifanele le-diluent yokomisa kancane ukuze unciphise ijubane lokomisa uyinki.

3, umbala wephethini uyashintshwa, umshini wokunyathelisa wewebhu, umshini wokunyathelisa we-flexo, umshini wokwenza izikhwama zemvilophu, umshini wokunyathelisa iphepha lezokwelapha, umshini wokusika imiqulu

Izizathu kanye nemibono yokwelashwa:

(1) Ukuthamba kweyinki kuyashintsha. Uma uthamba i-yinki, hlanganisa ngenkathi ufaka ukuze uyinki ichitheke ngokuphelele ku-solvent bese ulawula ukuthamba okufanele. Uma kungenzeka, iphampu yokujikeleza kwemishini ingangezwa ukuze kube nomphumela ongcono.

(2) Ngemva kokuba uyinki ususetshenziswe isikhathi esithile, engeza i-diluent ukuze unciphise ubuningi beyinki. I-diluent kufanele ifakwe njalo ngemizuzu engama-30 noma ngaphezulu. Ngemva kokufaka i-diluent izikhathi ezimbili kuya kwezingu-3, ​​ingxenye yoyinki wokuqala kufanele ifakwe ngesikhathi esifanayo futhi ivuselelwe ngokulinganayo ukuze kugwenywe ukwehla kokuhlushwa kweyinki.

4. Umshini wokunyathelisa wewebhu onemibala exubile Umshini wokunyathelisa we-Flexo Umshini wokwenza izikhwama ze-envelope Umshini wokunyathelisa iphepha lezokwelapha Umshini wokusika ama-roll

Ukuxuba imibala kusho ukuthi uyinki wombala olandelayo ungcoliswe umbala weyinki wombala wangaphambilini, noma umbala uyasakazwa bese uthuthwa.

Izizathu kanye neziphakamiso zokwelapha: Umshini wokunyathelisa iwebhu, umshini wokunyathelisa we-flexo, umshini wokwenza izikhwama zemvilophu, umshini wokunyathelisa iphepha lezokwelapha, umshini wokusika imiqulu

(1) Uyinki wombala wangaphambilini woma kancane kakhulu, noma uyinki wombala olandelayo woma ngokushesha kakhulu. Ngokwesimo esithile, sebenzisa isinyibilikisi esifanele (uyinki wombala wangaphambilini kumele womiswe kahle), noma ulungise izinga lokushisa lesistimu yokushisa yengxenye ngayinye.

(2) I-viscosity ye-inki iphakeme kakhulu. Nciphisa ngokufanele i-viscosity ye-inki. Umshini wokunyathelisa iwebhu Umshini wokunyathelisa we-Flexo Umshini wokwenza izikhwama ze-envelope Umshini wokunyathelisa iphepha lezokwelapha Umshini wokusika ama-roll

(3) Kuthintekile yi-plasticizer efilimini ye-substrate. Qonda izinhlobo nezinyathelo zokuphepha zama-plasticizer efilimini, bese ushintsha ifilimu uma ingafaneleki.

(4) Ukusetshenziswa kabi kwama-pigment namadayi ku-inki kubangela ukufuduka. Kufanele uzame ukugwema ukusebenzisa amadayi njengezinto zokusetshenziswa ukukhiqiza ama-inki.

5. Ukunamathela kokubuyisela emuva kwezinto eziphrintiwe

Izizathu kanye neziphakamiso zokwelapha: Umshini wokunyathelisa iwebhu, umshini wokunyathelisa we-flexo, umshini wokwenza izikhwama zemvilophu, umshini wokunyathelisa iphepha lezokwelapha, umshini wokusika imiqulu
