Ngesikhathi sokusebenza ngesivinini esikhulu kwe-central impression ci Flexo press, ugesi omile uvame ukuba yinkinga efihliwe kodwa elimaza kakhulu. Uyaqoqana buthule futhi ungabangela amaphutha ahlukahlukene ekhwalithi, njengokukhanga kothuli noma izinwele ku-substrate, okuholela ekunyathelisweni okungcolile. Kungase futhi kuholele ekuqhekekeni kweyinki, ukudluliselwa okungalingani, amachashazi angekho, noma imigqa elandelanayo (evame ukubizwa ngokuthi "ukushaya ama-whiskering"). Ngaphezu kwalokho, kungabangela izinkinga ezifana nokugoba okungaqondile kanye nokuvimba ifilimu, okuthinta kakhulu ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Ngakho-ke, ukuphatha ugesi omile ngempumelelo kube yinto ebalulekile ekuqinisekiseni ukuphrinta kwekhwalithi ephezulu.
Uvelaphi Ugesi Ongaguquki?
Ekuphrinteni kwe-flexographic, ugesi omile uqala kakhulu ezigabeni eziningi: isibonelo, amafilimu e-polymer (njenge-BOPP ne-PE) noma iphepha livame ukuxhumana ngokungqubuzana futhi lihlukaniswe nezindawo ezigoqekayo ngesikhathi sokuvuleka, ukubonakala okuningi, nokugoqa. Ukulawulwa okungafanele kokushisa okuzungezile kanye nomswakama, ikakhulukazi ngaphansi kwezimo zokushisa eziphansi nezomile, kwenza kube lula ukuqongelela ugesi omile. Uma kuhambisana nokusebenza okuqhubekayo kwesivinini esikhulu semishini, ukukhiqizwa kanye nokuhlanganiswa kwamanani kuyaba kubi kakhulu.

Izixazululo Zokulawula Ezihlelekile Ze-Electrostatic
1. Ukulawulwa Kwemvelo Okunembile: Ukugcina indawo yokusebenza eqinile nefanelekile kuyisisekelo sokusebenza kahle kwe-ci Flexo press. Gcina umswakama ungaphakathi kwebanga elingu-55%–65% RH. Umswakama ofanele uthuthukisa ukuhanjiswa komoya, okusheshisa ukuhlakazeka kwemvelo kukagesi ongashintshi. Izinhlelo zokufaka umswakama/ukususa umswakama ezithuthukisiwe zezimboni kufanele zifakwe ukuze kufezwe izinga lokushisa elilinganayo kanye nomswakama.

Isiqedi Esiqinile
2. Ukususwa Okuqinile Okusebenzayo: Faka Ama-Static Eliminators
Lesi yisisombululo esiqondile nesiyinhloko. Faka ama-emulators aqinile ezindaweni ezibalulekile:
●Iyunithi Yokuvula: Hlukanisa i-substrate ngaphambi kokuba ingene esigabeni sokuphrinta ukuze kuvinjelwe ukuthi amashaji angaguquki angathwalwa phambili.
●Phakathi Kweyunithi ngayinye Yokuphrinta: Susa izindleko ezikhiqizwe kuyunithi yangaphambilini ngemva kokushicilelwa ngakunye nangaphambi kokuphrinta okulandelayo ukuze ugweme ukuchitheka kweyinki nokubhaliswa kabi emshinini wokuphrinta we-CI flexographic.
● Ngaphambi Kweyunithi Yokubuyisela Umva: Qinisekisa ukuthi impahla isesimweni sokungathathi hlangothi ngesikhathi sokubuyisela umva ukuze kuvinjelwe ukungalungi noma ukuvimba.
3. Ukuthuthukiswa Kwezinto Eziphathekayo Nezinqubo:
● Ukukhethwa Kwezinto: Khetha ama-substrate anezakhiwo ezilwa nokungaguquguquki noma lezo eziphathwe ebusweni ukuze zisebenze ngokulwa nokungaguquguquki, noma ama-substrate ane-conductivity enhle ehambisana nenqubo yokuphrinta ye-flexography.
●Uhlelo Lokumisa Inhlabathi: Qinisekisa ukuthi umshini wokunyathelisa we-ci flexo unesistimu yokumisa inhlabathi ephelele nethembekile. Wonke ama-roller ensimbi kanye nohlaka lwemishini kufanele kumiswe kahle ukuze kuhlinzekwe indlela ephumelelayo yokukhipha amanzi angashukumi.
4. Ukugcinwa Nokuqapha Okuvamile: Gcina ama-guide rollers nama-bearings ehlanzekile futhi esebenza kahle ukuze ugweme ugesi ongaguquki obangelwa ukungqubuzana okungajwayelekile.
Isiphetho
Ukulawulwa kwe-electrostatic kwe-ci flexo rinting press kuyiphrojekthi ehlelekile engenakuxazululwa ngokuphelele ngendlela eyodwa. Kudinga indlela ebanzi kuzo zonke izigaba ezine: ukulawulwa kwemvelo, ukususwa okusebenzayo, ukukhethwa kwezinto, kanye nokugcinwa kwemishini, ukwakha uhlelo lokuvikela olunezingqimba eziningi. Ukubhekana nogesi ozinzile ngokwesayensi kubalulekile ekukhuliseni ikhwalithi yokuphrinta kanye nokususa imfucuza. Le ndlela inciphisa isikhathi sokungasebenzi futhi iqinisekisa ukukhiqizwa okusebenzayo kakhulu, okuzinzile, kanye nekhwalithi ephezulu.
