Ngenxa yeenzuzo zokunyanga ngokukhawuleza, ukonga amandla kunye nokukhuselwa kokusingqongileyo, iimveliso zokunyanga i-UV zisetyenziswa ngokubanzi kwiindawo ezininzi, kwaye zaqala ukusetyenziswa kakhulu kwintsimi yokwaleka ngamaplanga.Kwiminyaka yakutshanje, kunye nophuhliso lwabaqalisi abatsha, i-diluents esebenzayo kunye ne-oligomers ye-photosensitive, ukusetyenziswa kwe-UV ye-UV enyangekayo iye yanda ngokuthe ngcembe kwiindawo zephepha, iiplastiki, isinyithi, amalaphu, izixhobo zemoto njalo njalo.Oku kulandelayo kuza kwazisa ngokufutshane ukusetyenziswa kweeTekhnoloji ezininzi zokuNyanga i-UV kwiinkalo ezahlukeneyo.
UV ukunyanga 3D yoshicilelo
Ushicilelo lwe-3D olunyangekayo lwe-UV yenye yetekhnoloji ekhawulezayo yokuchwetheza enowona shicilelo oluchanekileyo kunye norhwebo.Ineengenelo ezininzi, ezifana nokusetyenziswa kwamandla aphantsi, ixabiso eliphantsi, ukuchaneka okuphezulu, umphezulu ogudileyo kunye nokuphindaphinda okulungileyo.Isetyenziswe ngokubanzi kwi-aerospace, i-automotive, imveliso yokubumba, ukuyila ubucwebe, ezonyango kunye nezinye iinkalo.
Umzekelo, ngokuprinta 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.
I-Stereolithography (i-SLA), i-digital projection (DLP), i-3D inki-jet forming (3DP), ukukhula kwenqanaba lolwelo oluqhubekayo (ikliphu) kunye nobunye ubuchwepheshe buphuhliswe ekuphiliseni ukukhanya kwe-3D iteknoloji yoshicilelo [3].Njengoko imathiriyeli yayo yoshicilelo, ifoto enyangekayo ye-photosensitive resin yoshicilelo lwe-3D nayo yenze inkqubela phambili enkulu, kwaye iphuhlisa ukuya ekusebenzeni 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 yeyona nto isetyenziswa kakhulu kwipakethe yeplastiki.Iimpawu ezigqwesileyo zoomatshini, ukuchasana nobushushu kunye nokufuma kusisiseko sokupakishwa komgangatho ophezulu.Ingxaki esisiseko emisela ukusebenza kwe-epoxy resin ayikona nje isakhiwo somzimba oyintloko we-epoxy resin, kodwa kunye neempembelelo ze-ejenti yokunyanga.
Xa kuthelekiswa nendlela yokunyanga i-thermal eyamkelwa yi-epoxy resin eqhelekileyo, ukunyanga kwe-cationic UV akugcini nje ngokuba nozinzo olungcono lokugcinwa kweekhemikhali ze-photoinitiator, kodwa kunye nesantya sokunyanga ngokukhawuleza kwenkqubo.Ukunyangwa kunokugqityezelwa kwimizuzwana yamashumi ngokusebenza okuphezulu kakhulu.Akukho inhibition ye-oxygen polymerization, kwaye inokunyangeka ngokunzulu.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 ye-UV iya kudlala indima ebaluleke ngakumbi kuphuhliso loshishino lokupakisha lwe-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 lwexesha elizayo.
Kukho iintlobo ezininzi zee-ink zokuprinta ze-flexo, ngokukodwa kubandakanywa iindidi ezilandelayo: ii-inki ezisekelwe emanzini, i-solvent based inki kunye ne-UV curing (UV) ii-inks.Ii-inki ezisekwe kwi-solvent zisetyenziswa ikakhulu kushicilelo lwefilimu yeplastiki engafunxayo;I-inki esekwe emanzini isetyenziswa ikakhulu kwiphephandaba, kwibhodi enezinki, kwikhadibhodi nakwezinye izinto zokuprinta;I-inki ye-UV inoluhlu olubanzi lokusetyenziswa.Inesiphumo esihle sokushicilela kwifilimu yeplastiki, iphepha, ifoyile yentsimbi kunye nezinye izinto.
I-inki ye-UV ineempawu zobuhlobo bokusingqongileyo, ukusebenza kakuhle okuphezulu, umgangatho olungileyo wokushicilela kunye nokuguquguquka okuqinileyo.Yi-inki entsha ethandwa kakhulu kwaye exhalabileyo yokhuseleko lokusingqongileyo okwangoku, kwaye inethemba elihle kakhulu lophuhliso.
I-inki yeFlexographic UV isetyenziswa kakhulu ekupakisheni nasekushicileleni.I-inki yeFlexo UV inezi ncedo zilandelayo:
(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 iipakethi ezineemfuno eziphezulu zezinto zokupakisha ezikhuselekileyo, ezingenayo ityhefu.
2Xa ushicilela nge-inki ye-viscosity ephezulu, umphumo wokushicilela uselungile.
(3) Isantya sokumisa i-inki siyakhawuleza kwaye imveliso yoshicilelo olusebenzayo luphezulu.Inokusetyenziswa ngokubanzi kwiindlela ezahlukeneyo zokuprinta, ezifana neplastiki, iphepha, ifilimu kunye nezinye ii-substrates.
Ngophuhliso lwesakhiwo esitsha se-oligomer, i-diluent esebenzayo kunye ne-initiator, umda wesicelo wexesha elizayo weemveliso zokunyanga ze-UV awunakulinganiswa, kwaye indawo yophuhliso lwemarike ayinasiphelo.
I-Microspectrum inohlalutyo olutyebileyo kunye namava ophando kwintsimi yeemveliso zokunyanga ze-UV.Yakhe isiseko sedatha ye-spectrogram enamandla kwaye inezixhobo ezipheleleyo zohlalutyo olukhulu.Ngokusebenzisa iindlela zobunikazi zesampulu yonyango kunye neendlela zokuhlalutya izixhobo, zinokumisela iimonomers zokwenziwa kunye nezakhiwo zeeoligomers ezahlukeneyo, iintlobo ngeentlobo zeediluents ezisebenzayo, iifotoinitiators kunye nezongezo zomkhondo, njl.njl Kwangaxeshanye, i-microspectrum ilandela ngokusondeleyo ukuphuculwa kweemveliso ezintsha kwimveliso entsha. kwimarike, kwaye iqhuba uphando lweprojekthi kwiimveliso ezintsha zonyango ze-UV kwiindawo ezininzi.Inokuthelekisa kwaye ihlalutye ukugqwesa kweemveliso, incede amashishini ukusombulula ubunzima kunye neendawo ezingaboniyo ezifunyenwe kwinkqubo yophuhliso lwemveliso, mfutshane umjikelo we-R & D kunye nokuphucula ukusebenza kwemveliso.
