Ngenxa yeenzuzo zokunyanga ngokukhawuleza, ukonga amandla kunye nokukhuselwa kwendalo, iimveliso zokunyanga ukukhanya zisetyenziswa ngokubanzi kwiinkalo ezininzi.Baqala ukusetyenziswa ikakhulu kwintsimi yokwaleka iinkuni.Kwiminyaka yakutshanje, ngophuhliso lwabaqalisi abatsha, i-diluents esebenzayo kunye ne-oligomers ye-photosensitive, ukusetyenziswa kwe-UV yengubo enyangekayo iye yanda ngokuthe ngcembe ukuya kumabala ephepha, iplastiki, isinyithi, amalaphu, iinxalenye zemoto njalo njalo.Oku kulandelayo kuza kwazisa ngokufutshane ukusetyenziswa kweetekhnoloji ezininzi zokunyanga ukukhanya kwiinkalo ezahlukeneyo.
UV ukunyanga 3D yoshicilelo
Ukukhanya okunyanga ukuprintwa kwe-3D yenye yetekhnoloji ekhawulezayo yokuchwetheza ngokuchaneka okuphezulu koshicilelo kunye norhwebo.Ineengenelo ezininzi, ezifana nokusetyenziswa kwamandla aphantsi, ixabiso eliphantsi, ukuchaneka okuphezulu, umphezulu ogudileyo kunye nokuphindaphinda okulungileyo.Isetyenziswe ngokubanzi kwi-aerospace, i-automobile, ukuveliswa kwe-mold, ukuyila ubucwebe, unyango lwezonyango kunye nezinye iinkalo.
Umzekelo, ngokushicilela iprototype ye-rocket injini enesakhiwo esintsonkothileyo kunye nokuhlalutya imowudi yokuhamba kwerhasi, kuyanceda ukuyila injini yerokethi enesakhiwo esixineneyo kunye nempumelelo ephezulu yokutsha, enokuphucula ngempumelelo i-R & D yamacandelo anzima kunye nciphisa umjikelo we-R & D wemoto;Ungaprinta kwakhona ukubumba okanye ukubuyisela umva ukubumba ngokuthe ngqo, ukuze wenze ukubumba ngokukhawuleza kunye nokunye.
Ukukhanya ukunyanga iteknoloji yoshicilelo lwe-3D iphuhlise iteknoloji yokubumba i-stereo lithography (SLA), iteknoloji ye-digital projection (DLP), ukubumba kwe-inkjet ye-3D (3DP), ukukhula kwenqanaba lolwelo okuqhubekayo (ikliphu) kunye nezinye iiteknoloji [3].Njengoko imathiriyeli yayo yoshicilelo, i-photosensitive resin yokunyanga ukukhanya kwe-3D yoshicilelo nayo yenze inkqubela phambili enkulu, kwaye iphuhlisa kwicala lokusebenza ngokweemfuno zesicelo.
Ukupakishwa kwe-elektroniki kweemveliso zokunyanga ze-UV
Ukutsha kweteknoloji yokupakisha ikhuthaza ukuguqulwa kwezinto zokupakisha ukusuka kwintsimbi yentsimbi kunye nokupakishwa kwe-ceramic ukuya kwiplastiki.I-epoxy resin isetyenziswa ngokubanzi kwipakethe yeplastiki.Iimpawu ezigqwesileyo zoomatshini, ukuchasana nobushushu kunye nokufuma kusisiseko sokupakishwa komgangatho ophezulu.Ingxaki esisiseko emisela ukusebenza kwe-epoxy resin ayisosakhiwo somzimba oyintloko we-epoxy resin, kodwa kunye nempembelelo ye-arhente yokunyanga.
Xa kuthelekiswa nendlela yokunyanga i-thermal eyamkelwa yi-epoxy resin yesiqhelo, ukunyanga kwe-UV ye-cationic akugcini nje ngokuba nozinzo olungcono lokugcinwa kweekhemikhali ze-photoinitiator, kodwa kunye nesantya sokunyanga kwenkqubo ngokukhawuleza.Ukunyangwa kunokugqitywa kumashumi emizuzwana, ngokusebenza okuphezulu kakhulu, akukho kuthintela i-oxygen polymerization kunye nokunyanga okunzulu.Ezi zibonelelo ziya ziqaqambisa ukubaluleka kwetekhnoloji yokunyanga ye-cationic UV kwintsimi yokupakishwa kwe-elektroniki.
Ngophuhliso olukhawulezayo lwetekhnoloji ye-semiconductor, amacandelo e-elektroniki athande ukudityaniswa kakhulu kunye ne-miniaturized.Ubunzima bokukhanya, amandla aphezulu, ukumelana nobushushu obuhle kunye neempawu ezibalaseleyo ze-dielectric ziya kuba yindlela yokuphuhlisa izinto ezintsha zokupakisha ze-epoxy eziphezulu.Itekhnoloji yokunyanga ukukhanya iya kudlala indima ebaluleke ngakumbi kuphuhliso lweshishini lokupakisha nge-elektroniki.
I-inki yokuprinta
Kwintsimi yokupakisha kunye nokushicilela, iteknoloji yokushicilela i-flexographic isetyenziswa ngakumbi nangakumbi, kubalwa ngokunyuka kwenani.Ibe bubuchwephesha obuqhelekileyo bokuprinta kunye nokupakishwa, kwaye yindlela engenakuthintelwa yophuhliso kwixesha elizayo.
Kukho iintlobo ezininzi zeenki ze-flexographic, ngokukodwa ezibandakanya iindidi ezilandelayo: ii-inki ezisekelwe emanzini, i-solvent based inki kunye ne-ultraviolet curing (UV) inki.I-inki esekwe kwi-solvent isetyenziswa ikakhulu kushicilelo lwefilim yeplastiki engafunxayo;I-inki esekwe emanzini isetyenziswa ikakhulu kwiphephandaba, kwibhodi enezinki, kwikhadibhodi nakwezinye izinto zokuprinta;I-inki ye-UV isetyenziswa ngokubanzi, kwaye inesiphumo esihle sokushicilela kwifilimu yeplastiki, iphepha, i-foil yesinyithi kunye nezinye izinto [4].
Okwangoku, i-inki yoshicilelo ye-UV ithandwa kakhulu kumgangatho wayo ophezulu kunye nokhuseleko lokusingqongileyo, kwaye inethemba elihle kakhulu lophuhliso.
I-inki yeFlexographic UV isetyenziswa kakhulu ekupakisheni ukupakisha.I-inki yeFlexographic UV ineenzuzo ezilandelayo
(1) I-inki ye-Flexographic ye-UV ayinayo ukukhutshwa kwe-solvent, ukusetyenziswa okukhuselekileyo nokuthembekileyo, indawo ephezulu yokunyibilika kwaye akukho ngcoliseko, ngoko ifanelekile ukwenza ukutya, amayeza, isiselo kunye nezinye iipakethe ezineemfuno eziphezulu zezixhobo zokupakisha ezikhuselekileyo, ezingenayo ityhefu.
2Xa ushicilela nge-inki ene-viscosity ephezulu, umphumo wokushicilela uselungile.
(3) Isantya sokumisa i-inki siyakhawuleza kwaye imveliso yoshicilelo olusebenzayo luphezulu.Inokusetyenziswa ngokubanzi kwiindlela ezahlukeneyo zokuprinta, ezifana neeplastiki, iphepha, ifilimu kunye nezinye izinto ezincinci.
Ngophuhliso lwesakhiwo esitsha se-oligomer, i-diluent esebenzayo kunye ne-initiator, umda wesicelo wexesha elizayo weemveliso zokunyanga ze-UV awunakulinganiswa, kwaye indawo yophuhliso lwemarike ayinamda.
