Saddex kulan oo kala go'a ayaa muujinaya tignoolajiyada ugu dambeeyay ee lagu bixiyo goobta daaweynta tamarta.
Mid ka mid ah waxyaabaha ugu muhiimsan ee shirarka RadTech waa fadhiyada ku saabsan tignoolajiyada cusub.MarkaRadTech 2022, waxaa jiray saddex fadhi oo loo qoondeeyey Hababka Heerka Xiga, oo leh codsiyo u dhexeeya baakadaha cuntada, dahaarka alwaax, dahaarka baabuurta iyo kuwo kale.
Foomamka Heerka Xiga I
Bruce Fillipo oo u dhashay Ashland ayaa hogaaminayay Habaynta Heerka Xiga ee kalfadhiga "Saamaynta Monomer ee Dahaarka Fiberka indhaha," eeg sida polyfunctionals u saameyn karto fiilooyinka indhaha.
"Waxaan heli karnaa monomer-ka isku-dhafka ah ee isku-dhafka ah ee leh qalabyo badan - xakamaynta viscosity iyo hagaajinta milanka," Filippo ayaa xusay.“Isku-xidhnaanta qaabaynta ee la hagaajiyay waxa ay sahlaysaa isku xidhka isku midka ah ee polyacrylates.
"Vinyl pyrrolidone waxay qiyaastay hantida guud ee ugu wanaagsan ee lagu soo bandhigay qaabeynta fibre-ga ee aasaasiga ah, oo ay ku jiraan xakamaynta viscosity aadka u fiican, dhererka sare iyo xoogga jilicsanaanta, iyo ka weyn ama siman heerka daaweynta vs. acrylates monofunctional kale ee la qiimeeyey," ayuu raaciyay Fillipo."Guryaha lagu bartilmaameedsado daahannada fiber-ka indhaha waxay la mid yihiin codsiyada kale ee UV-ga la daweyn karo sida khadadka iyo dahaarka gaarka ah."
Marcus Hutchins oo ka tirsan Allnex ayaa ku raacay "Helitaanka dahaarka dhalaalaya ee aadka u hooseeya ee Oligomer Naqshadeynta iyo Tignoolajiyada."Hutchins waxay ka wada hadleen dariiqyada 100% dahaarka UV ee leh wakiilada dahaarka, tusaale ahaan alwaax.
"Ikhtiyaarada dhimista dhalaalka dheeraadka ah waxaa ka mid ah resins leh shaqeyn hoose iyo horumarinta wakiilada matting," Hutchins ayaa raaciyay."Hoos u dhigista dhalaalka waxay keeni kartaa calaamado guur.Waxaad ku abuuri kartaa saameyn laalaab ah iyada oo loo marayo daaweynta excimer.Diyaarinta qalabku waxay fure u tahay hubinta dusha siman oo aan cillad lahayn.
"Dhamaysyo hoose oo matte ah iyo dahaarka waxqabadka sare ayaa noqda mid dhab ah," Hutchins ayaa raaciyay."Alaabooyinka la daweyn karo UV waxay si wax ku ool ah u matte karaan naqshadeynta molecule iyo tignoolajiyada, yaraynta cadadka walxaha daaqsinka ah ee loo baahan yahay iyo hagaajinta gubashada iyo caabbinta wasakhda."
Richard Plenderleith oo ka tirsan Sartomer ayaa markaa ka hadlay "Xeeladaha ku wajahan Dhimista Tahriibka ee Farshaxanka."Plenderleith waxay tilmaantay in qiyaastii 70% baakooyinka loogu talagalay baakadaha cuntada.
Plenderleith waxa ay intaa ku dartay in khadadka UV ee caadiga ahi aanay ku haboonayn baakadaha cuntada tooska ah, halka khadadka UV ee socdaalka hooseeya looga baahan yahay baakadaha cuntada dadban.
"Doorashada alaabta ceeriin ee la hagaajiyay ayaa fure u ah in la yareeyo khatarta socdaalka," ayay tiri Plenderleith."Arrimuhu waxay ka iman karaan wasakhaynta duubka inta lagu jiro daabacaadda, nalalka UV oo aan dhammaanayn, ama guuritaanka deminta marka la kaydiyo.Nidaamyada UV waa qayb ka mid ah kobaca warshadaha baakadaha cuntada maadaama ay tahay tignoolajiyada aan dareeraha lahayn."
Plenderleith waxay tilmaantay in shuruudaha baakadaha cuntada ay noqonayaan kuwo aad u adag.
"Waxaan aragnaa dhaqdhaqaaq xooggan oo loo socdo UV LED, iyo horumarinta xalal hufan oo buuxinaya shuruudaha daaweynta LED waa furaha," ayuu raaciyay."Hagaajinta falcelinta iyadoo la dhimayo socdaalka iyo khataraha waxay nooga baahan tahay inaan ka shaqeyno labadaba sawir-qaadayaasha iyo acrylates."
Camila Baroni oo ka tirsan IGM Resins ayaa xidhay Hababka Heerka Xiga ee I leh "Saamaynta Isku-dhafka ah ee Isku-dhafka Agabka Aminofunctional iyo Nooca I Photoinitiators."
"Xogta la muujiyay ilaa hadda, waxay u egtahay in qaar ka mid ah amiinada acrylated ay yihiin hor-joogayaal oksijiin ah oo wanaagsan waxayna leeyihiin awood ahaan isku-dubarid ahaan joogitaanka nooca 1 photoinitiators," ayuu yiri Baroni."Amiinada ugu firfircoon waxay keentay saameyn jaale ah oo aan loo baahnayn oo filimka la daweeyey.Waxaan u maleynay in jaallaha lagu yarayn karo hagaajinta waxyaabaha amiinada akrylated ah."
Hababka Xiga II
Hababka Xiga ee Heerarka II waxa ay ku bilowdeen "Qaybyada Qaybaha Yaryar ee Xidhmada Feer: Waxyaabo Lagu Kordhiyo si loo Hagaajiyo Waxqabadka Dusha Sare ee Dahaarka UV Ka Faa'idaysiga Isku-xidhanaanshaha, Nanoparticle Dispersions or Micronized Wax Options," oo uu soo bandhigay Brent Laurenti ee BYK USA.Laurenti waxay ka wadahadleen waxyaabaha lagu daro UV crosslinking, SiO2 nanomaterials, additives iyo PTFE-free technology.
"Waxyada aan lahayn PTFE-da waxay ina siinayaan waxqabad heersare ah codsiyada qaarkood, waxayna yihiin 100% biodegradable," Laurenti ayaa werisay."Waxay geli kartaa ku dhawaad qaab kasta oo daahan."
Waxaa ku xigay Tony Wang oo ka tirsan Allnex, kaasoo ka hadlay "Koriyeyaasha LED si loo hagaajiyo daawaynta dusha sare ee LED ee Codsiyada Litho ama Flexo."
"Ogsajiinta-ka-hortagga waxay joojisaa ama waxay baabi'isaa polymerization-ka xagjirka ah," Wang ayaa xusay."Waxay aad ugu daran tahay dahaarka khafiifka ah ama viscosity hoose, sida baakadaha baakadaha iyo khadadka.Tani waxay abuuri kartaa oog adag.Daaweynta dusha sare waxay aad ugu dhib badan tahay daawaynta LED sababtoo ah xoojinta hoose iyo qufulka hirarka gaaban."
Evonik's Kai Yang ayaa markaa ka hadlay "kor u qaadida ku-dhejinta tamarta la daweyn karo ilaa substrate adag - oo laga soo bilaabo dhinac wax lagu daro."
"PDMS (polydimethylsilozanes) waa fasalka ugu fudud ee siloxanes, waxayna bixiyaan xiisad aad u hooseeya oo aad u deggan," Yang ayaa arkay."Waxay bixisaa guryaha bilicda wanaagsan.Waxaan ku hagaajinay iswaafajinta annagoo wax ka beddelayna organic, kaas oo xakameynaya biyo-diidnimada iyo biyo-baxa.Guryaha la rabo waxaa lagu tolayn karaa kala duwanaansho qaabdhismeed.Waxaan ogaanay in polarity-ka sare uu hagaajiyo milanka UV matrix.TEGO Glide waxay gacan ka geysataa xakamaynta sifooyinka siloxanes-ka organomodified, halka Tego RAD ay hagaajiso silbashada iyo sii deynta."
Jason Ghaderi oo ka tirsan IGM Resins ayaa xidhay Hababka Xiga ee Heerarka II isaga oo hadalkiisa ku saabsan "Urethane Acrylate Oligomers: Dareenka Filimada La Daaweeyay ee UV Iftiinka iyo Qoyaanka leh iyo la'aanteed UV Absorbers."
"Dhammaan qaacidooyinka ku saleysan UA oligomers ma muujin wax huruud ah isha qaawan iyo wax jaale ah ama midab sida lagu cabbiro spectrophotometer," ayuu yiri Ghaderi."Urethane acrylate oligomers jilicsan ayaa muujiyay awood jilicsan oo hooseeya iyo modules iyaga oo muujinaya dherer sare.Waxqabadka oligomers-ka-adag wuxuu ahaa dhexda, halka oligomers adag ay keentay xoog xajin oo sarreeya iyo modules leh dherer hoose.Waxaa la arkay in xuubka UV-ga iyo HALS ay farageliyaan daawaynta, natiijaduna, isku xirka filimka la daweeyay ayaa ka hooseeya kan nidaamka ka maqan labadan.
Heerarka Xiga ee Hababka III
Hababka Xiga ee Heerarka III waxa uu soo bandhigay Joe Lichtenhan oo ka tirsan Hybrid Plastics Inc., kaas oo daboolay "Ku-darka POSS ee Kala-firdhinta iyo Xakamaynta Viscosity", oo u eeg sida POSS wax lagu daro, iyo sida loogu tixgalin karo wax lagu daro isku-dhafan ee caqliga leh ee nidaamyada dahaarka.
Lichtenhan waxaa ku xigtay Evonik's Yang, oo soo jeedintiisa labaad ahayd "Isticmaalka Silica Additives in UV Printing Inks."
"Qaabka daweynta UV/EB, silica oogada la daweeyay ayaa ah sheyga la door bidayo maadaama xasiloonida la taaban karo ay sahlanaan karto in la gaaro iyadoo la ilaalinayo viscosity wanaagsan ee codsiyada daabacaadda," Yang ayaa xusay.
"Ikhtiyaarada Dahaarka UV ee la daweyn karo ee Codsiyada Baabuurta Gudaha," waxaa qoray Kristy Wagner, Rinjiga Spot Cas, ayaa ku xigay.
"UV daahan cad oo midabaysan ayaa muujiyay in aanay la kulmin oo kaliya laakiin ay dhaafeen shuruudaha adag ee OEM ee codsiyada baabuurta gudaha," Wagner ayaa arkay.
Mike Idacavage, Radical Curing LLC, oo lagu xidhay "Urethane Oligomers Viscosity Low oo u shaqeeya sida Diluents Reactive", kaas oo uu xusay in loo isticmaali karo khad, daahan buufin ah iyo codsiyada daabacaadda 3D.
