Flexo Icapiro rya Corona Umuvuzi - Gukemura Ibibazo bya Adhesion mugucapisha firime byoroshye

Kugera neza kandi birebire - byacapwe byanditse biracyari ikibazo gikomeye kubahindura muburyo bwihuse - isi yihuta yo gupakira ibintu byoroshye. Ibibazo byoroshye byo gucapura firime birashobora kugira ingaruka kumurongo wanyuma wikigo no kumenyekana muguteza ibicuruzwa, kongera imyanda, no gusubiramo bihenze. Abayobozi b'inganda ubu bakoresha ikoreshwa rya Flexo Icapiro rya Corona Treater, ryageragejwe - na -, kugira ngo bakemure iki kibazo gikabije. Kugirango icapiro rya flexografiya rigende neza kubintu bitandukanye bitari - byoroshye, harimo polyester, firime metallised, polypropylene, na polyethylene, iki gisubizo cyo gutegura ubuso ni ngombwa.
Uku gukata - edge pre - tekinoroji yo kuvura yateguwe kugirango ihindure ingufu zubuso bwa firime zoroshye, zitanga ishingiro ryiza rishoboka ryigihe kirekire - rifatika rirambye, impuzu, na wino. Abavuzi ba Corona nigice cyingenzi cyo gutanga umusaruro - ubuziranenge, hejuru - imikorere yoroheje yo gupakira kuko bakemura neza ibibazo bya firime.
Kumenya ikibazo cya Flexography Core Adhesion Ikibazo
Icapiro rya Flexographic, rizwi neza - rizwiho kwihuta no guhuza n'ibikoresho byoroshye, bifite ikibazo cyihariye. Kuberako firime nyinshi za pulasitike zifite ingufu zubutaka zidasanzwe muri kamere, amazi nka wino isanzwe hamwe nudusimba twangwa nubuso butagaragara -. Ibi biganisha ku guhanagura bidahagije, bitera ibibazo birimo imbaraga zumubano udahagije, kunyerera wino, hanyuma amaherezo ugasiba mugihe cyo kuzuza, guhindura, cyangwa kurangiza - gukoresha.
Ndetse wino nziza ya flexo ntishobora kwomeka neza niba ubuso budakora neza. Filime na wino ntaho bihuriye rwose, bishimangira ko hakenewe inzira yo guhuza icyuho kandi ikizeza gukomera no kwizerwa.
Uburyo Ibibazo bya Adhesion Byakemuwe na Corona Umuvuzi
Uburyo bwo kuvura corona nuburyo bwiza ariko bugoye bwo guhindura isura. Itera hejuru ya firime hejuru y’umuriro mwinshi - w’amashanyarazi, uzwi kandi nka corona, ku muvuduko w’ikirere.
Ubumenyi bwo Gukora Ubumenyi
Gusohora corona bikorwa na electrode ndende - mugihe electrode yoroheje igenda hejuru ya roller yuzuye dielectric. Umwuka ukikijwe na ionisoni nu gusohora, bitanga plasma ya electroni yubusa, ozone, hamwe na ion ya ogisijeni ikora cyane. Iyo iyi plasma ikorana numurongo wa polymer hejuru ya firime, haratangizwa amatsinda yimikorere ya polar (nka karubone na hydroxyl) kandi imigozi ya molekile iracika.
Imbaraga zo hejuru ya firime yazamuwe cyane niyi mpinduka yimiti, yongera hydrophilicity na reactivite. Irangi ryamazi hamwe nigitambaro birashobora gukwirakwira kimwe (wet - hanze) hanyuma bigatera umurunga ukomeye, ubukanishi, nubumashini kuko kubutaka bushya bwakorewe hejuru ya molekile ikurura. Gucapa ibyananiranye byatsinzwe bigamije kandi bikurwaho nubu buryo.
Ibyiza byingenzi bya firime zihinduka
Hariho byombi bigufi - manda nigihe kirekire - inyungu zikorwa zo kwinjiza sisitemu yo kuvura corona mumurongo wo gucapa flexo:
Ubwiza bwo Kwandika Bwiza: Kuzamura ibishushanyo mbonera byemeza ko wino yuzuye, imwe itagira pinhole, amaso y amafi, cyangwa kunyerera.
Guhuza Ibikoresho Byagutse: Gushoboza gucapura kwizerwa kumurongo mugari wa substrate igoye, harimo laminates na firime polyolefin (PE, PP, na BOPP).
Kunoza imikorere Yizewe: Kugabanya imyanda yibintu, kwanga, nigihe cyo guterwa no gufatira hamwe - inenge zijyanye.
Imikorere myiza ya Downstream: Yemeza ubunyangamugayo bwa pake ya nyuma mugukomeza inkwano mugihe cyo kumurika no gufunga kashe.
Igiciro - gukora neza: Kugabanya ibikorwa bihenze kandi umukiriya agaruka mugihe uhitamo gukoresha wino nibikoresho.
Kuzamura uburyo bwo kuvura Corona
Gushiraho imiti ntabwo bihagije kugirango uhore ukemura ibibazo byo gufatira hamwe; bigomba kandi kunozwa no kubungabungwa.
Ibintu Byingenzi Kugenzura
Kugenzura neza ibi bikurikira birakenewe kugirango bivurwe neza:
Ingufu zo hejuru zapimwe nurwego rwa Dyne. Kwipimisha kenshi byemeza ko urwego rushobora guhuza cyangwa kurenga ibisabwa byashyizweho nuwatanze wino (mubisanzwe ingoma 38-44 / cm kubwinshi bwa wino ya flexo).
Ubucucike bwimbaraga: Ingano yimbaraga zikoreshwa zijyanye n'umuvuduko n'ubugari bwurubuga. Kugirango ibikorwa bibe byiza, hagomba kubaho watts zihagije.
Electrode Gap & Geometry: Ikintu kimwe, gihoraho cya corona gisohoka kurubuga rwose cyizerwa no guhuza neza no gutandukanya icyuho.
Kwishyira hamwe hamwe na Flexo Yumunsi
Imashini igezweho ya flexo icapa corona yakozwe kugirango ihuze byoroshye na servo - imashini zikoreshwa. Barashobora guhindura muburyo bwo kuvura bakurikije umuvuduko wumurongo hamwe nubwoko bwa substrate babikesha amashanyarazi akomeye hamwe nubugenzuzi bwikora, byemeza ibisubizo bihoraho kuva kumuzingo kugeza kumuzingo.
Ubuvuzi bwa Surface ejo hazaza mubikoresho byoroshye
Gukenera kuvura hejuru biziyongera gusa uko inganda zigenda ziyongera cyane - inzitizi ziterwa na mono - zifatika. Hamwe na sisitemu yo gucunga neza ozone hamwe namakuru yambere yinjira mubikorwa byinganda 4.0 gusesengura no kubungabunga ibizakurikiraho, ibikurikira - abavura corona bavura barushaho kuba ingufu - neza. Mu guca isoko - ku isoko, ikoranabuhanga rikomeje kuba ingenzi, ritezimbere igisubizo cyo gukemura ibibazo bitoroshye.
Inyandiko
Gukemura ibibazo bya adhesion mugucapisha firime byoroshye nibisabwa kubahindura mubikorwa byinganda zipakira. Ikigeragezo - na - ukuri, inganda - uburyo busanzwe bwo kubigeraho nubuvuzi bwa Flexo Icapa Corona. Gukurikiza wino isumba iyindi, ubuziranenge bwanditse bwanditse, hamwe nibikorwa byose byiringirwa birashoboka muguhindura byimazeyo ibiranga ubuso bwa polyolefine nizindi firime za plastiki. Gushora imari no kunoza sisitemu yo kuvura corona ya none ni intambwe ibarwa itezimbere mu buryo butaziguye imikorere y’ibicuruzwa, igabanya imyanda, kandi ikarinda uburinganire bw’ibicuruzwa, byemeza ko abahindura bashobora gukemura ibibazo byo gucapa firime byoroshye haba muri iki gihe ndetse no mu gihe kizaza.
