Ngexesha lokusebenza ngesantya esiphezulu kwe-central impression ci Flexo press, umbane ongashukumiyo uhlala uba yingxaki efihlakeleyo kodwa eyonakalisayo kakhulu. Uqokelelana buthule kwaye unokubangela iziphene ezahlukeneyo zomgangatho, njengokutsala kothuli okanye iinwele kwi-substrate, okubangela iiprinta ezingcolileyo. Ingakhokelela ekuqhekekeni kwe-inki, ukudluliselwa okungalinganiyo, amachaphaza angekhoyo, okanye imigca elandelelanayo (edla ngokubizwa ngokuba yi-"whiskering"). Ukongeza, inokubangela imiba efana nokujija okungalungelelananga kunye nokuvalwa kwefilimu, okuchaphazela kakhulu ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso. Ke ngoko, ukulawula umbane ongashukumiyo ngempumelelo kube yinto ebalulekileyo ekuqinisekiseni ukuprintwa komgangatho ophezulu.
Uvela phi umbane oqinileyo?
Kwiprinta ye-flexographic, umbane oshukumayo uvela kwizigaba ezahlukeneyo: umzekelo, iifilimu ze-polymer (ezifana ne-BOPP kunye ne-PE) okanye iphepha lihlala lidibana kwaye lahlukane neendawo ezijikelezayo ngexesha lokuvulwa, ukuvela okuninzi, kunye nokujika. Ulawulo olungalunganga lobushushu kunye nokufuma okungqongileyo, ngakumbi phantsi kweemeko zobushushu obuphantsi nezomileyo, lunceda ngakumbi ukuqokelelwa kombane oshukumayo. Xa kudibene nokusebenza okukhawulezayo kwezixhobo, ukuveliswa kunye nokuhlanganiswa kweentlawulo kuyaba mandundu.

Izisombululo zoLawulo lwe-Electrostatic eziCwangcisiweyo
1. Ulawulo Oluchanekileyo Lwendalo: Ukugcina indawo yokusebenzela izinzile kwaye ifanelekile sisiseko sokusebenza kakuhle kwe-ci Flexo press. Gcina umswakama ungaphakathi koluhlu lwe-55%–65% RH. Umswakama ofanelekileyo uphucula ukuhanjiswa komoya, okukhawulezisa ukusasazwa kwendalo kombane ongashukumiyo. Iinkqubo zokufumisa/zokususa umswakama kwimizi-mveliso eziphambili kufuneka zifakelwe ukuze kufezekiswe ubushushu kunye nomswakama ohambelanayo.

Isicoci Esiqinileyo
2. Ukususwa kweStatic okusebenzayo: Faka iiStatic Eliminators
Esi sesona sisombululo sithe ngqo nesiphambili. Faka ngokuchanekileyo ii-static eliminators kwiindawo eziphambili:
●Iyunithi Yokukhulula Umoya: Nciphisa i-substrate ngaphambi kokuba ingene kwicandelo lokuprinta ukuthintela ukuba ii-static charges zingathwalwa phambili.
●Phakathi kweYunithi nganye yokuPrinta: Susa iindleko eziveliswa kwiyunithi yangaphambili emva komfanekiso ngamnye nangaphambi kokuprinta okulandelayo ukuze uphephe ukuchitheka kwe-inki kunye nokubhaliswa gwenxa kumatshini wokuprinta we-CI flexographic.
● Ngaphambi kweYunithi yokuBuyela umva: Qinisekisa ukuba izinto zikwimeko engathathi cala ngexesha lokuBuyela umva ukuthintela ukungalungelelani okanye ukuvaleka.
3. Ukuphucula Izinto kunye neNkqubo:
● Ukukhetha Izinto: Khetha ii-substrates ezineempawu ezichasene ne-static okanye ezo ziphathwe ngaphezulu ukuze zisebenze ngokuchasene ne-static, okanye ii-substrates ezine-conductivity elungileyo ehambelana nenkqubo yokuprinta i-flexography.
●Inkqubo Yokumisa Ingca: Qinisekisa ukuba i-ci flexo press inenkqubo yokumisa ingca ebanzi nethembekileyo. Zonke iirola zesinyithi kunye neefreyimu zezixhobo kufuneka zimiswe ngokufanelekileyo ukuze zibonelele ngendlela esebenzayo yokukhupha ingca engashukumiyo.
4. Ukugcinwa nokuBekwa esweni rhoqo: Gcina ii-guide rollers kunye neebheringi zicocekile kwaye zisebenza kakuhle ukuze kuthintelwe umbane ongashukumiyo obangelwa kukungqubana okungaqhelekanga.
Isiphelo
Ulawulo lwe-electrostatic kwi-ci flexo rinting press yiprojekthi ecwangcisiweyo engenakulungiswa ngokupheleleyo ngendlela enye. Ifuna indlela ebanzi kumanqanaba amane: ulawulo lokusingqongileyo, ukususwa okusebenzayo, ukukhethwa kwezinto, kunye nokugcinwa kwezixhobo, ukwakha inkqubo yokukhusela eneeleya ezininzi. Ukujongana nombane oshukumayo ngokwesayensi kubalulekile ekunyuseni umgangatho wokuprinta kunye nokunciphisa inkunkuma. Le ndlela inciphisa ixesha lokungasebenzi kwaye iqinisekisa imveliso esebenza kakuhle, ezinzileyo, nesemgangathweni ophezulu.
