Mu njira yogwiritsira ntchito makina osindikizira, kuumitsa inki pang'onopang'ono komwe kumabweretsa kutayikira kwakhala vuto lalikulu kwa makampani osindikiza. Izi sizimangokhudza ubwino wosindikiza komanso zimawonjezera zinyalala komanso zimachepetsa magwiridwe antchito opangira ndipo zitha kuchedwetsa nthawi yotumizira. Kodi vutoli lingathetsedwe bwanji bwino? Timapereka yankho lathunthu lomwe limaphatikizapo kusankha inki, kukonza njira, kukweza zida, ndi kuwongolera chilengedwe kuti tikuthandizeni kuchotsa kutayikira ndikupeza kupanga kosindikiza kokhazikika komanso kogwira mtima kwambiri.

● Kusankha Inki & Kukonza Fomula - Kuthetsa Mavuto Ouma Patsamba
Pa makina osindikizira a flexo, kusankha ndi kupanga inki ndikofunikira kwambiri pothana ndi mavuto ouma. Tikukulimbikitsani kugwiritsa ntchito inki zouma mwachangu, monga inki zosungunuka zokhala ndi mapangidwe osinthasintha kwambiri kapena inki zosungunuka m'madzi zokhala ndi zolimbikitsira kuumitsa. Kuti ziume msanga kwambiri, inki za UV zolumikizidwa ndi makina ophikira a ultraviolet ndiye chisankho chabwino kwambiri. Kusintha ma solvent ratios—monga kuwonjezera kuchuluka kwa ethanol kapena ethyl acetate—kungathandize kuuma bwino pamene inki ikukhazikika. Kuphatikiza apo, kusankha zowonjezera zoyenera zouma (monga cobalt/manganese driers za inki zouma za okosijeni kapena zopenera zapadera za substrate zoyamwitsa) kumatsimikizira zotsatira zabwino kwambiri.
● Kukonzanso Makina Oumitsira - Kupititsa Patsogolo Kugwiritsa Ntchito Bwino
Kugwira ntchito kwa makina owumitsa mu makina osindikizira a flexo kumakhudza mwachindunji zotsatira zake. Yang'anani makina owumitsa nthawi zonse kuti muwonetsetse kuti kutentha kuli koyenera (50–80°C pa inki zosungunulira, kutsika pang'ono pamadzi) komanso mpweya wabwino. Pa ntchito zovuta, sinthani ku kuumitsa kwa infrared kuti mugwiritse ntchito bwino pamalopo kapena kuyeretsa kwa UV kuti muumitse nthawi yomweyo. Zipangizo zowumitsa mpweya wozizira ndizothandiza kwambiri pamakanema osayamwa kuti inki isanyowenso.
● Kukonza Njira Zosindikizira - Kusintha Ma Parameter Opangira
Mu makina osindikizira a flexographic, kukonza bwino magawo opangira kumathandizira kwambiri kuuma bwino. Kulamulira liwiro losindikiza ndikofunikira kwambiri—liwiro lopitirira muyeso limaletsa kuumitsa bwino musanasindikize siteshoni ina. Sinthani liwiro kutengera mawonekedwe a inki ndi mphamvu ya choumitsira. Kuwongolera makulidwe a filimu ya inki pogwiritsa ntchito kusankha bwino kwa anilox roller ndi kuchuluka kwa inki kumalepheretsa kusonkhanitsa kwambiri. Pa kusindikiza kwamitundu yambiri, kuwonjezera malo oimikapo kapena kuwonjezera zoumitsira pakati pa siteshoni kumawonjezera nthawi youma.
● Kusintha kwa Chilengedwe ndi Pansi pa Madzi - Zinthu Zofunika Kwambiri Zakunja
Mkhalidwe wa chilengedwe pa ntchito za flexo printer umakhudza kwambiri kuumitsa. Sungani kutentha kwa pansi pa sitolo pa 20–25°C ndi chinyezi pa 50–60%. Gwiritsani ntchito zochotsera chinyezi m'nyengo yonyowa. Kusamalira pansi pa nthaka (monga kuchiza korona wa mafilimu a PE/PET) kumawonjezera kumatirira kwa inki ndikuchepetsa zolakwika pakuuma.
Chithandizo cha Corona
Kulamulira Chinyezi
Pomaliza, dongosolo lolimba losamalira limatsimikizira kukhazikika kwa nthawi yayitali. Nthawi zonse yeretsani ma nozzles a dryer ndi zinthu zotenthetsera, yang'anani kuwonongeka kwa anilox roller, ndikugwiritsa ntchito zoyezera dry-tension kuti muwone ubwino wa zosindikizidwa—njira zofunika kwambiri popewera mavuto okhudzana ndi kuuma.
