Uruhare rukomeye rwingufu zubuso
Muburyo bwo guhatanira amasoko ya digitale na offset yo gucapa, kugera kumurongo mwiza wo gucapa, gufatana, no kuramba nibyingenzi. Urufunguzo, nyamara akenshi munsi ya - rwashyizwe hejuru, ikintu muriki gikorwa ni imbaraga zubuso bwa substrate. Urupapuro - ibikoresho bishingiye, uhereye ku mpapuro zometseho na firime ya sintetike kugeza kuri polymers biodegradable, bikunze kwerekana ingufu nke zo hejuru, biganisha ku gutembera nabi no gufatira wino hamwe no gutwikira. Ubuvuzi bwa Corona bumaze igihe kinini bushyizweho nkubuhanga bukomeye bwo guhindura isura kugirango iki kibazo gikemuke. Mugutanga plasma igenzurwa, abavuzi ba corona bongera ingufu zubutaka bwibikoresho, bityo bagahindura ibyasohotse nibikorwa.
Gusobanukirwa Ibyingenzi byo Kuvura Corona
Ubuvuzi bwa Corona nubuhanga bwo guhindura ibintu bukoresha - ubushyuhe buke corona isohora plasma kugirango itange impinduka mumiterere yubuso. Inzira ikubiyemo kubyara plasma hagati ya electrode na roller ihagaze hejuru ya substrate. Iyi plasma ikorana nubuso bwa substrate, ikora amatsinda yimikorere ya polar (nka karubone na hydroxyls) byongera ingufu zubutaka kandi bikongerera ubushuhe. Kubicapura porogaramu, ibi bisobanurwa kuri wino imwe imwe, guhuza imbaraga, no kunoza icapiro ryihuta.
Imikorere yubuvuzi ipimirwa muri dynes / cm (ingufu zubutaka). Filime itavuwe neza, nkurugero, irashobora kugira ingufu zubutaka munsi ya 30 - 35 ingoma / cm, mugihe icapiro ryiza risaba urwego ruri hejuru yingoma 40-50 / cm. Kuvura Corona birashobora kuzamura byimazeyo izo ndangagaciro kurwego rusabwa, bigatuma ndetse wino itoroshye ishingiye kumazi yubahiriza neza insimburangingo nka aside polylactique (PLA).
Gukwirakwiza ibipimo by'urupapuro - Bishingiye kuri Substrates
Kunonosora imiti ya corona ntabwo arimwe - ingano - ihuye - byose. Urupapuro - rwagaburiwe ibikorwa muburyo bwa digitale na offset, ibice byinshi byingenzi bigomba guhindurwa neza:
1. Substrate Ibigize hamwe nubushake:Urwego rwo kuvura rugomba guhuzwa nibikoresho. Non - firime yubukorikori (urugero, PET, OPP) isaba ubukana butandukanye nubuvanganzo, impapuro zometseho cyangwa ibinyabuzima byangiza umubiri. Kurenza - kuvura impapuro birashobora kwangiza fibre, mugihe munsi ya - kuvura firime bizatanga umusaruro mubi.
2. Ububasha bwo Kuvura (Watts / ft² / min):Nibintu nyamukuru bigenzura urwego rwo guhindura isura. Ubucucike buri hejuru bwongera ingufu zubuso cyane. Ubuvuzi bwa corona bugezweho hamwe na - ikoreshwa na ceramic electrode yemerera kugenzura neza iyi variable, ituma optimizasiyo ya substrate yihariye hamwe na wino.
3. Igishushanyo cya Electrode hamwe na Sisitemu Iboneza:Guhitamo hagati ya - ubugari na electrode igabanijwe ni ngombwa kurupapuro - rushingiye. Segiteri ya electrode ituma uburyo bwo kuvura cyangwa kugenzura zone, bifite agaciro mukuvura ahantu runaka wurupapuro cyangwa kubakira ubugari bwurubuga rutandukanye mumuzingo - kugeza - ibikorwa byurupapuro. Ubwiza bwa dielectric butwikiriye kuri roller yubutaka nabwo bugira uruhare runini muburyo bwo kuvura kandi bugabanya ibyangiritse cyangwa ibyangiritse.
4. Kuvura uburinganire no gusaza:Ubuvuzi buhoraho kurupapuro rwose ni ngombwa kubwiza bumwe bwo gucapa. Byongeye kandi, ingaruka zo kuvura corona zirashobora kugabanuka mugihe - ikintu kizwi nka "gusaza." Optimisation ikubiyemo kwemeza ko urwego rwokuvura ruhagije kugirango ugumane neza mu icapiro, gutwikira, no kurangiza - gukoresha ubuzima bwibicuruzwa.
5. Kwishyira hamwe n'imirongo y'Itangazamakuru:Kugirango bikore neza, abavuzi ba corona bagomba kwinjizwa muburyo bwo gucapa, akenshi bigahita bihita mbere yo gucapa cyangwa gutwikira. Ibi byemeza ko substrate iri muburyo bwakirwa neza iyo ihuye na wino.
Inyungu zo gusaba muri Digital na Offset Icapiro
Gutezimbere kuvura corona bitanga inyungu zifatika muburyo bwombi bwo gucapa:
Kuri Offset Icapiro:Iremeza neza amavuta - ishingiye kuri wino hamwe no gutwikira kumpapuro zitandukanye - ububiko bwagaburiwe, harimo UV - impapuro zometse hamwe nubukorikori. Ibi bigabanya irangi wino - kuzimya, byongera amabara meza, kandi ni ngombwa kubikoresho byo hejuru - bipfunyika kandi byandika mubucuruzi.
Kubicapiro bya Digital (urugero, HP Indigo, Inkjet):Inkingi nyinshi za digitale, cyane cyane amazi - zishingiye na wino ya latex, zifite uburemere buke hejuru kandi ziharanira gukurikiza ingufu nke -. Ubuvuzi bwa Corona nibyingenzi mugushoboza hejuru - icapiro ryiza rya digitale kuri firime zipakirwa byoroshye, ibirango, hamwe nimbaho zidasanzwe, kwagura ikoreshwa rya progaramu ya digitale.
Gushoboza ibikoresho birambye:Mugihe inganda zijya kuri biopolymers nka PLA, kuvura corona bitanga uburyo burambye bwo gutanga ibyo bikoresho bya hydrophobique byacapwe. Ibi bishyigikira iyemezwa ryimikorere irambye itabangamiye imikorere yandika.
Umwanzuro hamwe nibikorwa byiza
Gutezimbere imiti ya corona kumpapuro - ishingiye kubutaka ni ishoramari ryibikorwa bifitanye isano itaziguye nubwiza bwanditse, gukora neza, hamwe nibintu byinshi. Intsinzi ishingiye ku bufatanye nabatanga ibikoresho babimenyereye bashobora gutanga ibisubizo byihariye bishingiye kubuhanga bwimbitse bwo gusaba. Mucapyi agomba gukora ibizamini bya dyne buri gihe kugirango akurikirane imikorere yubuvuzi kandi ahindure sisitemu. Urebye kuvura corona ntabwo ari ingirakamaro gusa ahubwo ni inzira isobanutse neza, icapiro rirashobora gufungura imikorere ihanitse haba muri substrate zabo hamwe na za mashini zabo, byujuje ibisabwa - byiyongera kubisabwa kugirango habeho ubuziranenge no guhanga udushya mu buhanzi bw’ubukorikori.
