Chifukwa cha ubwino wochiritsa mwamsanga, kupulumutsa mphamvu ndi kuteteza chilengedwe, mankhwala ochiritsa kuwala amagwiritsidwa ntchito kwambiri m'madera osiyanasiyana.Anayamba kugwiritsidwa ntchito makamaka m'munda wa matabwa.M'zaka zaposachedwa, ndi chitukuko cha oyambitsa atsopano, diluents yogwira ndi oligomers photosensitive, ntchito UV zokutira ochiritsika pang'onopang'ono kukodzedwa ku minda ya mapepala, mapulasitiki, zitsulo, nsalu, mbali galimoto ndi zina zotero.Zotsatirazi zifotokoza mwachidule kugwiritsa ntchito matekinoloje angapo ochiritsa kuwala m'magawo osiyanasiyana.
Kusindikiza kwa UV 3D
Kuwala kuchiritsa kwa 3D kusindikiza ndi imodzi mwamakina ofulumira a prototyping omwe ali ndi kusindikiza kolondola kwambiri komanso kutsatsa.Ili ndi zabwino zambiri, monga kugwiritsa ntchito mphamvu zochepa, zotsika mtengo, zolondola kwambiri, zosalala komanso zobwerezabwereza bwino.Zakhala zikugwiritsidwa ntchito kwambiri muzamlengalenga, magalimoto, kupanga nkhungu, kupanga zodzikongoletsera, chithandizo chamankhwala ndi zina.
Mwachitsanzo, posindikiza injini ya roketi yokhala ndi mawonekedwe ovuta komanso kuwunika momwe gasi amayendera, ndizothandiza kupanga injini ya rocket yokhala ndi mawonekedwe ophatikizika komanso kuyaka bwino kwambiri, komwe kumatha kusintha bwino magwiridwe antchito a R & D a magawo ovuta komanso kufupikitsa kuzungulira kwagalimoto R & D;Mukhozanso kusindikiza nkhungu kapena kusintha nkhungu mwachindunji, kuti mupange nkhungu mofulumira ndi zina zotero.
Kuwala kuchiritsa 3D kusindikiza luso lapanga stereo lithography akamaumba luso (SLA), digito projection luso (DLP), 3D inkjet akamaumba (3DP), mosalekeza madzi mlingo kukula (kakanema) ndi matekinoloje ena [3].Monga zinthu zake zosindikizira, utomoni wa photosensitive wochiritsa kuwala kwa 3D kusindikiza wapitanso patsogolo kwambiri, ndipo akupanga njira yogwirira ntchito molingana ndi zosowa za ntchito.
Kupaka pakompyuta kwa UV mankhwala ochiritsa
Ukadaulo waukadaulo wazolongedza umalimbikitsa kusintha kwa zida zonyamula kuchokera pakuyika zitsulo ndi ma CD a ceramic kupita kumapulasitiki.Epoxy resin imagwiritsidwa ntchito kwambiri pakuyika pulasitiki.Zabwino kwambiri zamakina, kutentha ndi kukana chinyezi ndizomwe zimayambira pamapangidwe apamwamba.Vuto lalikulu lodziwika bwino la utomoni wa epoxy sikuti limangokhala mawonekedwe a thupi lalikulu la epoxy resin, komanso mphamvu ya machiritso.
Poyerekeza ndi njira yochiritsira yotentha yomwe imatengedwa ndi epoxy resin wamba, kuchiritsa kwa cationic UV sikungokhala ndi kukhazikika kwamafuta osungira a photoinitiator, komanso kuthamanga kwa machiritso kwadongosolo kumathamanga.Kuchiritsa kumatha kutha mumasekondi khumi, ndikuchita bwino kwambiri, popanda choletsa cha oxygen polymerization komanso kuchiritsa kozama.Ubwinowu umachulukirachulukira kufunikira kwaukadaulo wochiritsa wa cationic UV pagawo lazonyamula zamagetsi.
Ndi chitukuko chofulumira chaukadaulo wa semiconductor, zida zamagetsi zimakhala zophatikizika kwambiri komanso zocheperako.Kulemera kopepuka, mphamvu yayikulu, kukana kutentha kwabwino komanso zinthu zabwino kwambiri za dielectric zidzakhala njira yachitukuko ya zida zatsopano zopangira ma epoxy.Ukadaulo wochiritsa wopepuka utenga gawo lofunikira kwambiri pakukula kwamakampani opanga zinthu zamagetsi.
Inki yosindikiza
M'munda wa ma CD ndi kusindikiza, teknoloji yosindikizira ya flexographic imagwiritsidwa ntchito mochulukirapo, ndikuwerengera kuchuluka kwa chiwerengero.Zakhala ukadaulo wodziwika bwino pakusindikiza ndi kuyika, ndipo ndiye njira yosapeŵeka yachitukuko m'tsogolomu.
Pali mitundu yambiri ya inki ya flexographic, makamaka kuphatikizapo magulu otsatirawa: inki zamadzi, zosungunulira zosungunulira ndi ma ultraviolet curing (UV) inki.Inki yosungunulira imagwiritsidwa ntchito makamaka posindikiza filimu yapulasitiki yosayamwa;Inki yochokera kumadzi imagwiritsidwa ntchito makamaka m'manyuzipepala, malata, makatoni ndi zida zina zosindikizira;Inki ya UV imagwiritsidwa ntchito kwambiri, ndipo imakhala ndi zotsatira zabwino zosindikizira mufilimu yapulasitiki, mapepala, zojambula zachitsulo ndi zipangizo zina [4].
Pakalipano, inki yosindikizira ya UV ndi yotchuka kwambiri chifukwa cha khalidwe lake lapamwamba komanso chitetezo cha chilengedwe, ndipo ali ndi chiyembekezo chabwino kwambiri cha chitukuko.
Inki ya Flexographic UV imagwiritsidwa ntchito kwambiri pakusindikiza.Inki ya Flexographic UV ili ndi izi zabwino
(1) Flexographic UV inki alibe zosungunulira, ntchito otetezeka ndi odalirika, malo osungunuka kwambiri ndipo palibe kuipitsa, choncho ndi oyenera kupanga chakudya, mankhwala, chakumwa ndi ma CD zina ndi zofunika mkulu kwa otetezeka, sanali poizoni ma CD zipangizo.
(2) Pamene kusindikiza, katundu thupi la inki kukhalabe zosasinthika, palibe zosungunulira kosakhazikika, mamasukidwe akayendedwe akadali zosasinthika, ndi mbale yosindikiza sadzakhala kuonongeka, chifukwa mbale phala, mbale stacking ndi zochitika zina.Mukasindikiza ndi inki yokhala ndi mamasukidwe apamwamba, zotsatira zosindikiza zimakhala zabwino.
(3) Kuthamanga kwa inki kumathamanga kwambiri ndipo ntchito yosindikiza yosindikiza ndiyokwera kwambiri.Itha kugwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zosindikizira, monga mapulasitiki, mapepala, filimu ndi magawo ena.
Pakupangidwa kwa mawonekedwe atsopano a oligomer, diluent yogwira ntchito komanso kuyambitsa, kuchuluka kwazinthu zochiritsira za UV sikungatheke, ndipo malo otukula msika alibe malire.
