Pa nthawi yogwira ntchito mwachangu kwambiri ya central impression ci Flexo press, magetsi osasunthika nthawi zambiri amakhala vuto lobisika koma lowononga kwambiri. Amasonkhana mwakachetechete ndipo angayambitse zolakwika zosiyanasiyana, monga kukoka fumbi kapena tsitsi ku substrate, zomwe zimapangitsa kuti pakhale zosindikizira zodetsedwa. Zingayambitsenso kufalikira kwa inki, kusamutsa kosagwirizana, madontho osowa, kapena mizere yotsatizana (nthawi zambiri imatchedwa "whiskering"). Kuphatikiza apo, zingayambitse mavuto monga kupotoza kolakwika ndi kutsekeka kwa filimu, zomwe zimakhudza kwambiri magwiridwe antchito opanga komanso mtundu wa zinthu. Chifukwa chake, kuyang'anira bwino magetsi osasunthika kwakhala kofunikira kwambiri kuti zitsimikizire kusindikiza kwabwino kwambiri.
Kodi Magetsi Osasunthika Amachokera Kuti?
Mu kusindikiza kwa flexographic, magetsi osasunthika amachokera makamaka m'magawo angapo: mwachitsanzo, mafilimu a polima (monga BOPP ndi PE) kapena mapepala nthawi zambiri amakumana ndi zinthu zozungulira komanso amasiyana ndi malo ozungulira akamamasuka, kujambulidwa kambirimbiri, komanso kuzunguliridwa. Kuwongolera kutentha ndi chinyezi molakwika, makamaka kutentha kochepa komanso kouma, kumathandizanso kuti magetsi osasunthika azisonkhana. Kuphatikiza ndi kugwira ntchito mwachangu kwa zidazi, kupanga ndi kusonkhanitsa magetsi kumawonjezeka.

Mayankho Oyendetsera Zinthu Mwadongosolo
1. Kuwongolera Zachilengedwe Molondola: Kusunga malo ogwirira ntchito okhazikika komanso oyenera ndiye maziko a magwiridwe antchito abwino a ci Flexo press. Sungani chinyezi mkati mwa 55%–65% RH. Chinyezi choyenera chimathandizira kuyendetsa bwino mpweya, ndikufulumizitsa kutayikira kwachilengedwe kwa magetsi osasinthasintha. Makina apamwamba oyeretsera/kuchotsa chinyezi m'mafakitale ayenera kukhazikitsidwa kuti akwaniritse kutentha ndi chinyezi chokhazikika.
Kulamulira Chinyezi
Chochotsa Chosasunthika
2. Kuchotsa Mosasinthasintha Kogwira Ntchito: Ikani Zochotsa Mosasinthasintha
Iyi ndi njira yolunjika komanso yofunikira kwambiri. Ikani bwino zochotsera zosasunthika pamalo ofunikira:
●Chigawo Chotsegula: Chotsani gawo lapansi musanalowe mu gawo losindikizira kuti musanyamule mphamvu zokhazikika.
●Pakati pa Chigawo Chilichonse Chosindikizira: Chotsani ndalama zomwe zapangidwa kuchokera ku chipangizo cham'mbuyomu pambuyo pa chizindikiro chilichonse komanso musanasindikizenso china kuti mupewe kufalikira kwa inki ndi kulembetsa molakwika pa makina osindikizira a CI flexographic.
● Musanayambe Kubwezeretsa Chipangizo: Onetsetsani kuti zinthuzo zili pamalo osalowerera ndale panthawi yobwezeretsa chipangizo kuti zisasokonezeke kapena kutsekeka.
3. Kukonza Zinthu ndi Njira:
● Kusankha Zinthu: Sankhani zinthu zokhala ndi zinthu zotsutsana ndi static kapena zomwe zakonzedwa pamwamba kuti zigwire ntchito bwino, kapena zinthu zokhala ndi conductivity yabwino yomwe ikugwirizana ndi njira yosindikizira ya flexography.
●Dongosolo Lokhazikika: Onetsetsani kuti makina osindikizira a ci flexo ali ndi njira yokhazikika komanso yodalirika. Ma roller onse achitsulo ndi mafelemu a zida ayenera kukhazikika bwino kuti apereke njira yothandiza yotulutsira madzi mosasunthika.
4. Kusamalira ndi Kuyang'anira Mwachizolowezi: Sungani ma guide rollers ndi ma bearing oyera komanso ogwira ntchito bwino kuti mupewe magetsi osakhazikika omwe amabwera chifukwa cha kukangana kosazolowereka.
Mapeto
Kulamulira kwa electrostatic kwa makina osindikizira a ci flexo ndi ntchito yokonzedwa bwino yomwe singathe kuthetsedwa kwathunthu ndi njira imodzi. Imafuna njira yonse m'magawo anayi: kuwongolera zachilengedwe, kuchotsa mwachangu, kusankha zinthu, ndi kukonza zida, kuti apange njira yotetezera yokhala ndi zigawo zambiri. Kuthana ndi magetsi osasunthika mwasayansi ndikofunikira kwambiri pakukweza mtundu wa kusindikiza ndi kudula zinyalala. Njira iyi imachepetsa nthawi yogwira ntchito ndipo imatsimikizira kupanga kogwira mtima kwambiri, kokhazikika, komanso kwabwino kwambiri.
