Ukuqhathaniswa kwezinhlelo zokwelashwa kwe-corona zokupakishwa kwepulasitiki nokuphrinta kwezimboni
Ezweni elisheshayo-lokupakishwa kwepulasitiki nokuphrinta kwemboni, ukuthola oyinki, ama-coatings, nama-laminates ukuze kuhlangane kahle kuyinkinga enkulu. Ukwelashwa kwe-Corona sekuphenduke ubuchwepheshe obubalulekile bokuxazulula le nkinga ngokushintsha indawo engaphezulu yama-substrates, okwandisa amandla awo angaphezulu kanye nokumanzisa kwawo. Le nqubo isebenzisa i-corona, engugesi{3}ophumayo onamandla amakhulu, ukuze i-ionze umoya oyizungezile. Lokhu kwenza izinhlobo ezisebenzayo ezikhipha i-oxidize ebusweni bento.
1. Izingxenye eziyinhloko kanye nobuchwepheshe besistimu
Into esemqoka eyenziwa uhlelo lokwelapha i-corona ukudala ukuphuma kukagesi okulawulwayo ngomfutho womoya. I-plasma esebenzayo eyakheka phakathi nalokhu kuphuma yengeza amaqembu asebenzayo e-polar (njenge-carbonyl ne-hydroxyl) endaweni engaphezulu-yezinto ezisetshenziswayo zamandla-eziphansi njenge-polyester (PET), i-pololefins (PE, PP), namafilimu ensimbi. Lolu shintsho lubaluleke kakhulu ekuqinisekiseni ukuthi amabhondi aqinile ayenziwa ekunyatheliseni kamuva noma ezinqubweni zokumboza. Kunezingxenye ezimbili eziyinhloko ezinhlelweni: amajeneretha nama-applicators.
Amajeneretha: Lawa madivayisi enza -amandla kagesi emvamisa ephezulu adingekayo ukuze kuphume i-corona. Zinamandla ahlukene aphumayo namaza. Amajeneretha amasha aqinile{3}angcono kunamamodeli asekelwe ku-transformer amadala{4}ngoba akunika ukulawula okwengeziwe, asebenza kahle kakhulu, futhi anokwethenjelwa.
Izisetshenziswa nama-electrode: Le ngxenye ithumela amandla ebusweni bento. Ezinye izinhlobo ezijwayelekile ziyi-bare-roll, emboziwe{2}}i-roll, namasistimu e-electric{3}}emboziwe e-electrode. Ukukhetha kuncike ezintweni ezifana nobubanzi bewebhu, isivinini somugqa, uhlobo lwempahla, nezinga lokwelashwa elidingekayo.
2. Izidingo zezinhlelo zokusebenza ezithile kanye nomehluko phakathi kwamasistimu
Umbono oyisisekelo uyafana, kepha izidingo zokufakwa kwepulasitiki nokuphrinta kwezimboni zidinga ukulungiselelwa okuhlukile kwesistimu.
Isetshenziselwa ukupakisha ipulasitiki:
Imboni yokupakisha eguquguqukayo ibhekene nezinselele eziyingqayizivele ngoba incike kakhulu ekunyatheliseni kwe-flexographic kanye ne-rotogravure. Amafilimu epulasitiki amancane,{1}}azwelayo nokuzwela ukushisa izinto ezivamile. Le mboni idinga abelaphi be-corona ukwenza lokhu okulandelayo:
Ukwelashwa Okufanayo Nokunembayo: Ukuze ugweme izinkinga zokuphrinta ezifana nokuxosha uyinki noma amandla ebhondi e-lamination abuthakathaka, amandla angaphezulu kufanele afane kuwebhu yonke. Amasistimu anamadizayini ama-electrode athuthukisiwe kanye{1}}nokuqapha isikhathi sangempela, njengohlelo lwe-MonTEC, olulandelela ukuthi i-electrode ngayinye iphuma kahle kangakanani, awusizo kakhulu.
-Ukuhambisana Kwesivinini: Imigqa yokupakisha ivamise ukushesha kakhulu. Ukuze izinhlelo zeCorona zisebenze kahle, zidinga ukuthi zikwazi ukunikeza ukwelashwa okusebenzayo ngaphandle kokunciphisa izinto. Lokhu kusho ukuthi badinga amajeneretha aqinile kanye nokupholisa ama-electrode okusebenzayo.
Ukulimala Kwefilimu Okuncane: Ukwelashwa kufanele kukhuphule amandla angaphezulu ngaphandle kokubanga i-oxidation eningi, izimbobo, noma ukuhlanekezela okushisayo kwamafilimu abuthakathaka.
Isetshenziselwa ukuphrinta kwemboni:
Leli qembu elikhulu lihlanganisa ukuphrinta ezintweni ezifana namapulasitiki aqinile, izindwangu, ama-foil, namakhadibhodi kathayela. Izidingo lapha zivame ukuhluka:
Amandla Nokungena: Izinto ezisetshenziswayo zingaba zijiyile, zibe nokuthungwa okwengeziwe, noma zibe namandla angaphezulu okuqala amancane. Ukuqinisekisa ukuthi umphumela we-corona udlula ezintweni ezingcolisayo noma ufika ezintweni eziyisisekelo, amasistimu angadinga ukukhiqiza amandla engeziwe.
Ukuqina Nokuguquguquka: Imishini yezimboni kufanele ikwazi ukusebenza ngaphansi kwezimo ezinzima. Amasistimu avame ukwakhiwa ukuze kube lula ukuwanakekela futhi asebenze ngohlu olubanzi lwezinhlobo ze-substrate nobubanzi.
Ukuhlanganiswa nezinqubo ezihlukahlukene: Ngaphezu kokunyathelisa, ukwelashwa kungase kudingeke ukuze kuhlanganiswe, ukubopha, noma ukuhlobisa. Eminye imishini ingasetshenziswa ngokuhambisana namasistimu emigqeni yokukhiqiza eyinkimbinkimbi.
3. Izinto Ezibalulekile Ongaziqhathanisa Lapho Ukhetha
Kubaphathi bokuthenga kanye nabathengi bezobuchwepheshe, ukukhetha uhlelo olungcono kakhulu lokwelapha i-corona kusho ukubheka okungaphezu nje kwezindleko zokuqala. Izinto ezibalulekile ongaziqhathanisa yilezi:
Ukusebenza Kahle Kokwelapha Nokulawula: Amandla okufinyelela njalo nokugcina izinga elithile lamandla angaphezulu (kukalwa ngama-dynes/cm). Avaliwe-amasistimu okulawula iluphu anezindlela zempendulo athembeke kakhulu.
Ukusebenza Ngekhono Lokusebenza: Izindleko zokuqhuba ibhizinisi nokuphepha kwezisebenzi zithinteka ngokuqondile ukuthi angakanani amandla asetshenziswayo, ukuthi i-ozone ilawulwa kanjani, nokuthi kulula kangakanani ukugcina ama-electrode.
Ukusekela Kobuchwepheshe Nokwethembeka: Ulwazi lomkhiqizi, ukutholakala kwezingxenye ezisele, nokuthi zisabela ngokushesha kangakanani ezicelweni zesevisi konke kubalulekile ekugcineni isikhathi sokuphumula sibe sincane. Abahlinzeki{1}}abadala abasunguliwe, njengalabo asebenesikhathi baklama futhi benza lezi zinhlelo amashumi eminyaka, ngokuvamile banikeza ukwethembeka{2}}kwesikhathi eside.
Ukukala kanye nokwenza ngendlela oyifisayo: Uhlelo lungaba imodeli evamile noma lwenziwe ukuthi lulingane nezidingo ezithile zokukhiqiza, njengezinhlelo zezokwelapha noma zezimoto ezidinga ama-electrode akhethekile ezingxenye ze-3D.
4. Isiphetho kanye Namathemba Ekusasa
Ukuhlaziya okuqhathanisayo kukhombisa ukuthi alukho uhlelo olulodwa lokwelapha olusebenzela wonke umuntu one-corona. Uma kuziwa ekufakweni kwepulasitiki, kugxilwa ekunembeni, isivinini, nokuphathwa ngokucophelela kwamafilimu. Ngakolunye uhlangothi, izinhlelo zokusebenza zokunyathelisa zezimboni zivame ukubeka amandla, ukuqina, nokusebenza ngezindlela ezihlukahlukene kuqala. Lobu buchwepheshe buya ngobuhlakani futhi buhlanganiswe ngokwengeziwe njengoba buthuthuka. Ngokuzayo, singalindela ukuxhumana okungcono kwe-IoT ukuze kulungiswe kusengaphambili, ukusetshenziswa kwamandla okuncane, kanye nobuchwepheshe obusha be-plasma obunikeza ukulawula okwengeziwe-kwesizukulwane esilandelayo. Ekugcineni, ukutshalwa kwezimali okuhle kuncike ekuhlolweni okupheleleyo kobuchwepheshe okucabangela izakhiwo zezinto ezibonakalayo, amapharamitha okucubungula, nezinjongo zokukhiqiza zamasu.
