Ngenxa yezinzuzo zokuphulukisa okusheshayo, ukonga amandla nokuvikelwa kwemvelo, imikhiqizo yokwelapha ukukhanya isetshenziswa kabanzi emikhakheni ehlukahlukene.Zaqale zasetshenziswa ikakhulukazi emkhakheni wokugqoka izinkuni.Eminyakeni yamuva nje, ngokuthuthukiswa kweziqalisi ezintsha, ama-diluent asebenzayo kanye nama-oligomers azwelayo, ukusetshenziswa kwezingubo ezilaphekayo ze-UV kuye kwanda kancane kancane emasimini ephepha, amapulasitiki, izinsimbi, izindwangu, izingxenye zezimoto nokunye.Okulandelayo kuzokwethula kafushane ukusetshenziswa kobuchwepheshe obumbalwa bokuphulukisa ukukhanya emikhakheni ehlukene.
Ukuphrinta kwe-3D yokwelapha kwe-UV
Ukuphrinta kwe-3D okuphulukisa ukukhanya kungenye yobuchwepheshe be-prototyping obusheshayo obunokunemba okuphezulu kakhulu kokuphrinta nokudayisa.Inezinzuzo eziningi, ezifana nokusetshenziswa kwamandla aphansi, izindleko eziphansi, ukunemba okuphezulu, indawo ebushelelezi kanye nokuphindaphinda okuhle.Isetshenziswe kabanzi ku-aerospace, imoto, ukukhiqiza isikhunta, ukuklama ubucwebe, ukwelashwa kanye neminye imikhakha.
Isibonelo, ngokuphrinta i-prototype ye-rocket injini enesakhiwo esiyinkimbinkimbi kanye nokuhlaziya imodi yokugeleza kwegesi, kuyasiza ukuklama injini yerokhethi enesakhiwo esihlangene kanye nokusebenza kahle okuphezulu komlilo, okungathuthukisa ngempumelelo ukusebenza kahle kwe-R & D kwezingxenye eziyinkimbinkimbi futhi finyeza umjikelezo wemoto we-R & D;Ungakwazi futhi ukuphrinta isikhunta noma ukuhlehlisa isikhunta ngokuqondile, ukuze wenze isikhunta ngokushesha nokunye.
Ubuchwepheshe bokuphrinta obukhanyayo be-3D buthuthukise ubuchwepheshe bokubumba i-stereo lithography (i-SLA), ubuchwepheshe be-digital projection (DLP), ukubumba kwe-inkjet ye-3D (3DP), ukukhula kwezinga loketshezi okuqhubekayo (isiqeshana) nobunye ubuchwepheshe [3].Njengempahla yayo yokuphrinta, i-photosensitive resin yokwelapha ukukhanya ukuphrinta kwe-3D nayo yenze inqubekelaphambili enkulu, futhi ithuthuka ngendlela yokusebenza ngokuya ngezidingo zohlelo lokusebenza.
Imikhiqizo yokwelapha ye-UV yokupakishwa ye-elekthronikhi
Ukuqanjwa kabusha kobuchwepheshe bokupakisha kukhuthaza ukuguqulwa kwezinto zokupakisha kusuka emaphaketheni ensimbi namaphakheji e-ceramic kuya emaphaketheni epulasitiki.I-Epoxy resin isetshenziswa kabanzi emaphaketheni epulasitiki.Izakhiwo ezinhle kakhulu zemishini, ukumelana nokushisa nomswakama kuyisisekelo sokupakishwa kwekhwalithi ephezulu.Inkinga eyisisekelo enquma ukusebenza kwe-epoxy resin akuyona nje isakhiwo somzimba oyinhloko we-epoxy resin, kodwa futhi nomthelela we-ejenti yokwelapha.
Uma kuqhathaniswa nendlela yokwelapha eshisayo eyamukelwa i-epoxy resin evamile, ukuphulukiswa kwe-cationic UV akugcini nje ngokuba nokuqina okungcono kokugcinwa kwamakhemikhali kwe-photoinitiator, kodwa futhi isivinini sokuphulukisa sohlelo siyashesha.Ukwelapha kungaqedwa emashumini amasekhondi, ngokusebenza kahle okuphezulu kakhulu, akukho ukuvinjelwa kwe-oxygen polymerization kanye nokwelapha okujulile.Lezi zinzuzo ziya ngokuya zigqamisa ukubaluleka kobuchwepheshe bokwelapha be-cationic UV emkhakheni wokupakisha nge-elekthronikhi.
Ngokuthuthuka okusheshayo kobuchwepheshe be-semiconductor, izingxenye ze-elekthronikhi zivame ukuhlanganiswa kakhulu futhi zenziwe zibe zincane.Isisindo esilula, amandla aphezulu, ukumelana nokushisa okuhle kanye nezakhiwo ezinhle kakhulu ze-dielectric kuzoba umkhuba wokuthuthukisa wezinto ezintsha zokupakisha ze-epoxy ezisebenza kahle kakhulu.Ubuchwepheshe bokuphulukisa ukukhanya buzodlala indima ebaluleke kakhulu ekuthuthukisweni kwemboni yokupakisha nge-elekthronikhi.
Uyinki wokuphrinta
Emkhakheni wokupakisha nokuphrinta, ubuchwepheshe bokuphrinta be-flexographic busetshenziswa kakhulu, kubalwa ngenani elikhulayo.Sekuphenduke ubuchwepheshe obujwayelekile bokuphrinta nokupakisha, futhi kuwumkhuba ongenakugwemeka wentuthuko esikhathini esizayo.
Kunezinhlobo eziningi zamayinki e-flexographic, ikakhulukazi kufaka phakathi izigaba ezilandelayo: oyinki abasekelwe emanzini, oyinki abasekelwe ku-solvent kanye noyinki we-ultraviolet curing (UV).Uyinki osuselwe ku-solvent usetshenziselwa ikakhulukazi ukuphrinta ifilimu yepulasitiki engamunzi;Uyinki osuselwe emanzini usetshenziswa kakhulu ephephandabeni, ebhodini likathayela, emakhadibhodi nakwezinye izinto zokunyathelisa;Uyinki we-UV usetshenziswa kabanzi, futhi unomphumela omuhle wokuphrinta kufilimu yepulasitiki, iphepha, ucwecwe lwensimbi nezinye izinto [4].
Njengamanje, uyinki yokuphrinta ye-UV idume kakhulu ngekhwalithi yayo ephezulu nokuvikelwa kwemvelo, futhi inethemba elihle kakhulu lentuthuko.
Uyinki we-Flexographic UV usetshenziswa kakhulu ekuprintweni kokupakisha.Uyinki we-Flexographic UV unezinzuzo ezilandelayo
(1) Uyinki we-Flexographic we-UV awunawo ukukhishwa kwe-solvent, ukusetshenziswa okuphephile nokuthembekile, indawo ephezulu yokuncibilika futhi akukho kungcola, ngakho ulungele ukwenza ukudla, umuthi, isiphuzo nokunye ukupakisha okunezidingo eziphezulu zezinto zokupakisha eziphephile, ezingenabuthi.
(2) Lapho unyathelisa, izakhiwo ezingokomzimba zikayinki zihlala zingashintshile, ayikho i-solvent eguquguqukayo, i-viscosity ihlala ingashintshiwe, futhi ipuleti lokunyathelisa ngeke lonakaliswe, okuholela ekunamathiseleni kwepuleti, ukupakishwa kwepuleti nezinye izenzakalo.Uma uphrinta ngoyinki one-viscosity ephezulu, umphumela wokuphrinta usemuhle.
(3) Ijubane lokumisa uyinki liyashesha futhi ukusebenza kahle kokuphrinta umkhiqizo kuphezulu.Ingasetshenziswa kabanzi ezindleleni ezihlukahlukene zokunyathelisa, njengepulasitiki, iphepha, ifilimu nezinye izinto ezingaphansi.
Ngokuthuthukiswa kwesakhiwo esisha se-oligomer, i-diluent esebenzayo nesiqalisi, ububanzi bokusebenza besikhathi esizayo bemikhiqizo yokwelapha ye-UV ayinakulinganiswa, futhi indawo yokuthuthukiswa kwemakethe ayinamkhawulo.
