Sababtoo ah faa'iidooyinka daaweynta degdega ah, badbaadinta tamarta iyo ilaalinta deegaanka, alaabta daweynta iftiinka ayaa si ballaaran loo isticmaalaa meelo kala duwan.Waxaa markii hore loo isticmaali jiray beerta dahaarka alwaax.Sanadihii la soo dhaafay, iyada oo horumarinta initiators cusub, diluents firfircoon iyo oligomers photosensitive, codsiga ee daahan daawaynta UV ayaa si tartiib tartiib ah balaartay in ay beeraha warqad, balaastikada, biraha, dharka, qaybaha baabuurta iyo wixii la mid ah.Kuwa soo socda ayaa si kooban u soo bandhigi doona adeegsiga dhowr tignoolajiyada daaweynta iftiinka ee dhinacyo kala duwan.
UV daawaynta 3D daabacaadda
Daabacaadda 3D ee iftiinka ayaa ah mid ka mid ah tignoolajiyada wax-soo-saarka degdega ah ee leh saxnaanta daabacaadda ugu sarreysa iyo ganacsigeyn.Waxay leedahay faa'iidooyin badan, sida isticmaalka tamarta yar, qiimaha jaban, saxnaanta sare, dusha siman iyo soo celinta wanaagsan.Waxaa si weyn loogu isticmaalay hawada sare, baabuurta, wax soo saarka caaryada, naqshadaynta dahabka, daawaynta iyo qaybaha kale.
Tusaale ahaan, adoo daabacaya prototype engine gantaal oo leh qaab dhismeed adag iyo falanqaynta habka socodka gaaska, waxaa waxtar leh in la naqshadeeyo mishiinka gantaalaha oo leh qaab dhismeed badan iyo waxtarka gubashada sare, kaas oo si wax ku ool ah u wanaajin kara waxtarka R & D ee qaybaha adag iyo gaabin baabuurka R & wareegga wareegga;Waxa kale oo aad si toos ah u daabacan kartaa caaryada ama u rogi kartaa caaryada, si aad si dhakhso ah u sameyso caaryada iyo wixii la mid ah.
Tiknoolajiyada daabacaadda ee 3D ee iftiinka ayaa horumarisay tignoolajiyada wax-qabashada stereo lithography (SLA), tignoolajiyada saadaalinta dhijitaalka ah (DLP), 3D inkjet molding (3DP), kobaca heerka dareeraha joogtada ah (clip) iyo teknoolojiyad kale [3].Sida walaxda daabacaadda, resin photosensitive for light-daabacaadda 3D ayaa sidoo kale sameeyay horumar weyn, oo ku soo koraya jihada functionalization iyadoo loo eegayo baahida codsiga.
Baakadaha elektiroonigga ah ee alaabta lagu daweeyo UV
Hal-abuurka tignoolajiyada baakadaha waxay kor u qaadaysaa kala-guurka alaabta baakadaha laga bilaabo baakadaha birta iyo baakadaha dhoobada ilaa bacaha caagga ah.Resin Epoxy waxaa si weyn loogu isticmaalaa baakadaha balaastiga ah.Qalabka farsamada ee aadka u fiican, kulaylka iyo iska caabbinta qoyaanka ayaa ah dhismaha baakadaha tayada sare leh.Dhibaatada aasaasiga ah ee lagu go'aaminayo waxqabadka xabagta epoxy ma aha oo kaliya qaab dhismeedka jirka ugu muhiimsan ee resin epoxy, laakiin sidoo kale saameynta wakiilka daaweynta.
Marka la barbar dhigo habka daweynta kulaylka ee uu qaatay resin epoxy-ga caadiga ah, daawaynta cationic UV kaliya ma leh xasilloonida kaydinta kiimikada ka wanaagsan ee photoinitiator, laakiin sidoo kale xawaaraha daaweynta ee nidaamku waa dhakhso.Daawaynta waxaa lagu dhammeyn karaa tobanaan ilbiriqsi gudahood, iyadoo leh waxtar aad u sarreeya, ma jiro xannibaado oksijiin polymerization ah iyo daaweyn qoto dheer.Faa'iidooyinkani waxay si isa soo taraysa u muujinayaan muhiimada cationic UV ee tignoolajiyada daawaynta ee goobta baakadaha elektiroonigga ah.
Iyada oo horumarka degdega ah ee tignoolajiyada semiconductor, qaybaha elektiroonigga ah waxay u muuqdaan inay noqdaan kuwo si heersare ah isku dhafan oo loo yareeyey.Miisaanka fudud, xoogga sare, caabbinta kulaylka wanaagsan iyo sifooyinka dielectric aadka u fiican ayaa noqon doona isbeddelka horumarinta ee qalabka cusub ee epoxy-ga cusub.Tiknoolajiyada daaweynta iftiinka ayaa door muhiim ah ka ciyaari doonta horumarinta warshadaha baakadaha elektiroonigga ah.
Khad daabacan
Dhinaca baakadaha iyo daabacaadda, tignoolajiyada daabacaadda flexographic ayaa loo isticmaalaa in ka badan iyo in ka badan, xisaabinta saamiga sii kordhaya.Waxay noqotay tignoolajiyada caadiga ah ee daabacaadda iyo baakadaha, waana horumarka lama huraanka ah ee horumarka mustaqbalka.
Waxaa jira noocyo badan oo ka mid ah khadadka flexographic, oo ay ku jiraan qaybaha soo socda: khadadka biyaha ku salaysan, khadyada ku salaysan dareeraha iyo ultraviolet curing (UV).Khad ku salaysan millatariga waxaa inta badan loo isticmaalaa daabacaadda filimada caagga ah ee aan nuugayn;Khadka biyaha ku salaysan waxaa inta badan lagu isticmaalaa wargeysyada, looxa jiingadaha, kartoonada iyo agabka kale ee daabacaadda;Khad UV ah ayaa si weyn loo isticmaalaa, waxayna leedahay saameyn daabacan oo wanaagsan oo ah filim caag ah, warqad, bir bir ah iyo qalab kale [4].
Waqtigan xaadirka ah, khad daabacaadda UV ayaa aad caan u ah tayada sare iyo ilaalinta deegaanka, waxayna leedahay rajo horumarineed oo aad u wanaagsan.
Khad Flexographic UV ayaa si weyn loogu isticmaalaa daabacaadda baakadaha.Khadka UV Flexographic wuxuu leeyahay faa'iidooyinka soo socda
(1) Khadka Flexographic UV ma laha wax dareere ah, isticmaal badbaado leh oo la isku halayn karo, barta dhalaalida sare iyo wasakh la'aan, sidaa darteed waxay ku habboon tahay samaynta cuntada, daawada, cabitaanka iyo baakadaha kale ee leh shuruudo sare oo loogu talagalay alaabta baakadaha badbaadsan, aan sunta ahayn.
(2) Marka daabacaadda, sifooyinka jireed ee khad aan isbeddelin, ma jiraan wax dareere ah, viscosity ayaa weli ah mid aan isbeddelin, iyo saxanka daabacaadda ma dhaawacmi doono, taasoo keentay dhajinta saxanka, dhejinta saxanka iyo ifafaale kale.Marka lagu daabaco khad leh viscosity sare, saamaynta daabacadu wali waa wanaagsan tahay.
(3) Xawaaraha qalajinta khadku waa dhakhso iyo waxtarka daabacaadda alaabadu waa mid sareysa.Waxaa si ballaaran loogu isticmaali karaa habab daabacaado kala duwan, sida balaastiig, warqad, filim iyo substrates kale.
Iyadoo horumarinta qaab-dhismeedka oligomer cusub, diluent firfircoon iyo hindise, baaxadda codsiga mustaqbalka ee alaabta daaweynta UV waa mid aan la qiyaasi karin, iyo booska horumarinta suuqa waa aan xad lahayn.
