Saddex kalfadhi oo kala go'an ayaa soo bandhigaya teknoolojiyada ugu dambeeyay ee laga bixinayo goobta daaweynta tamarta.
Mid ka mid ah waxyaabaha ugu muhiimsan shirarka RadTech waa fadhiyada ku saabsan teknoolojiyada cusub.RadTech 2022, waxaa jiray saddex kalfadhi oo loogu talagalay Qaababka Heerka Xiga, iyadoo la adeegsanayo codsiyo u dhexeeya baakadaha cuntada, dahaarka alwaaxa, dahaarka baabuurta iyo waxyaabo kaloo badan.
Qaaciidooyinka Heerka Xiga I
Bruce Fillipo oo ka tirsan Ashland ayaa hoggaaminayay kalfadhiga Next Level Formulations I oo ay ka soo muuqdeen "Impact Monomer on Optical Fiber Coatings," oo ah aragti ku saabsan sida polyfunctionals-ku u saameyn karaan fiilooyinka indhaha.
"Waxaan heli karnaa sifooyin monomer monofunctional ah oo isku-dhafan oo leh polyfunctionals - xakamaynta viscosity iyo milmida la hagaajiyay," ayuu yiri Filippo. "Isku-dhafka qaab-dhismeedka ee la hagaajiyay wuxuu fududeeyaa isku-xirka isku-dhafka ah ee polyacrylates.
"Vinyl pyrrolidone wuxuu cabiray sifooyinka guud ee ugu wanaagsan ee la siiyay qaab-dhismeedka fiber-ka indhaha ee aasaasiga ah, oo ay ku jiraan xakamaynta viscosity-ga aadka u fiican, fidinta sare iyo xoogga jiidista, iyo heerka bogsashada oo ka weyn ama siman marka loo eego acrylates-ka kale ee la qiimeeyay ee monofunctional," ayuu raaciyay Fillipo. "Sifooyinka lagu bartilmaameedsaday dahaarka fiber-ka indhaha waxay la mid yihiin codsiyada kale ee la daaweyn karo ee UV sida khad iyo dahaarka gaarka ah."
Marcus Hutchins oo ka tirsan Allnex ayaa ku xigay "Gaaritaanka Dahaarka Dhalaalaya ee Aad u Hooseeya iyada oo loo marayo Naqshadeynta iyo Tiknoolajiyadda Oligomer." Hutchins waxay kala hadleen dariiqyada loo maro dahaarka UV 100% iyadoo la adeegsanayo wakiilada roogagga, tusaale ahaan qoryaha.
"Xulashooyinka lagu dhimayo dhalaalka dheeraadka ah waxaa ka mid ah resins leh shaqo hoose iyo horumarinta wakiilada matting," ayuu raaciyay Hutchins. "Hoos u dhigista dhalaalku waxay horseedi kartaa calaamado qalloocan. Waxaad abuuri kartaa saameyn laalaab ah iyada oo loo marayo daaweynta excimer. Dejinta qalabka ayaa fure u ah hubinta dusha siman oo aan lahayn cillado.
"Dhammaystir yar oo matte ah iyo dahaadh tayo sare leh ayaa noqonaya kuwo dhab ah," ayuu raaciyay Hutchins. "Alaabta la daweyn karo ee UV-ga ayaa si wax ku ool ah u matte kara iyada oo loo marayo naqshadeynta iyo tignoolajiyada molecule-ka, taasoo yaraynaysa tirada walxaha matting-ka loo baahan yahay iyo hagaajinta iska caabbinta gubashada iyo wasakhda."
Richard Plenderleith oo ka tirsan Sartomer ayaa markaas ka hadlay "Istaraatiijiyadaha ku wajahan yareynta awoodda socdaalka ee Farshaxanka Sawir-gacmeedka." Plenderleith wuxuu tilmaamay in qiyaastii 70% baakadaha loogu talagalay baakadaha cuntada.
Plenderleith wuxuu raaciyay in khad UV caadi ah aysan ku habboonayn baakadaha cuntada tooska ah, halka khad UV oo socdaal yar loo baahan yahay baakadaha cuntada aan tooska ahayn.
"Xulashada walxaha ceeriin ee la hagaajiyay ayaa fure u ah yareynta khatarta socdaalka," ayuu yiri Plenderleith. "Dhibaatooyinku waxay ka dhici karaan wasakhowga duubista inta lagu jiro daabacaadda, nalalka UV-ga oo aan bogsanayn, ama socdaalka shidista marka la kaydiyo. Nidaamyada UV-gu waa qayb ka mid ah kobaca warshadaha baakadaha cuntada maadaama ay tahay tignoolajiyad aan lahayn dareere."
Plenderleith waxay tilmaamtay in shuruudaha baakadaha cuntada ay sii adkaanayaan.
"Waxaan aragnaa dhaqdhaqaaq xooggan oo loo sameynayo UV LED, horumarinta xalal wax ku ool ah oo buuxinaya shuruudaha daaweynta LED-ka ayaa muhiim ah," ayuu raaciyay. "Horumarinta falcelinta iyadoo la yareynayo socdaalka iyo khataraha waxay u baahan tahay inaan ka shaqeyno labadaba sawir-qaadayaasha iyo acrylates."
Camila Baroni oo ka tirsan Resin-ka IGM ayaa soo gabagabeysay Qormooyinka Heerka Xiga I iyadoo leh "Saamaynta Isku-dhafka ah ee Isku-darka Agabka Aminofunctional iyo Sawir-qaadayaasha Nooca I."
"Xogta ilaa hadda la muujiyay, waxay u egtahay in qaar ka mid ah amiinada acrylated ay yihiin kuwa hakiya oksijiinta wanaagsan waxayna leeyihiin awood ay ku noqdaan isku-dubarid marka ay joogaan nooca 1aad ee photoinitiators," ayuu yiri Baroni. "Amiinada ugu falcelinta badan waxay horseedeen saameyn huruud ah oo aan loo baahnayn oo filimka la daaweeyay ah. Waxaan u maleynay in huruudaynta la yareyn karo iyadoo la hagaajinayo waxa ku jira amiinada acrylated."
Qaaciidooyinka Heerka Xiga II
Qaababka Heerka Xiga II waxay ku bilaabmeen "Cabbirrada Yaryar ee Qaybaha ah ee Xiran: Xulashooyinka lagu daro si loo hagaajiyo waxqabadka dusha sare ee Dahaarka UV iyadoo la adeegsanayo Kala-goysyada Isku-xidhan, Kala-baxa Nanoparticle ama Xulashooyinka Wax-soo-saarka Micronized," oo uu soo bandhigay Brent Laurenti oo ka tirsan BYK USA. Laurenti wuxuu ka hadlay waxyaabaha lagu daro isku-xidhka UV, qalabka nano ee SiO2, waxyaabaha lagu daro iyo tiknoolajiyada wax-soo-saarka ee aan lahayn PTFE.
"Wax-soo-saarka aan lahayn PTFE waxay na siinayaan waxqabad heer sare ah codsiyada qaarkood, waana 100% kuwo baaba'aya," ayuu Laurenti ku sheegay. "Waxay geli kartaa ku dhawaad qaab kasta oo dahaadh ah."
Waxaa xigay Tony Wang oo ka tirsan Allnex, kaasoo ka hadlay "Kobciyeyaasha LED-ka si loo hagaajiyo daaweynta dusha sare ee LED-ka ee loogu talagalay Codsiyada Litho ama Flexo."
"Ka hortagga oksijiinta waxay damisaa ama baabi'isaa polymerization-ka xagjirka ah," Wang ayaa xusay. "Waa mid aad uga daran dahaarka khafiifka ah ama hooseeya ee viscosity, sida dahaarka baakadaha iyo khad. Tani waxay abuuri kartaa dusha sare oo dhegdheg leh. Daawaynta dusha sare way ka adag tahay daawaynta LED-ka sababtoo ah xoojinta hoose iyo qufulka hirarka gaaban."
Kai Yang oo ka tirsan Evonik ayaa markaa ka hadlay "Kor u qaadista Ku dhegganaanta Tamarta ee La Daaweyn Karo Substrate-ka Adag - Laga soo bilaabo Dhinac Ku-darka."
"PDMS (polydimethylsilozanes) waa nooca ugu fudud ee siloxanes, waxayna bixiyaan xiisad dusha sare ah oo aad u hooseysa waana mid aad u deggan," Yang ayaa arkay. "Waxay bixisaa sifooyin wanaagsan oo simbiriirixan. Waxaan hagaajinay iswaafajinta iyadoo la adeegsanayo wax ka beddelka dabiiciga ah, kaas oo xakameynaya hydrophobicity iyo hydrophilicity. Astaamaha la doonayo waxaa lagu habeyn karaa kala duwanaanshaha qaabdhismeedka. Waxaan ogaanay in polarity sare ay hagaajiso milmida matrix-ka UV. TEGO Glide waxay ka caawisaa xakamaynta sifooyinka siloxanes-ka organomodized, halka Tego RAD ay hagaajiso simbiriirixan iyo sii deyn."
Jason Ghaderi oo ka tirsan IGM Resins ayaa soo gabagabeeyay Next Level Formulations II isagoo khudbaddiisa ku saabsan "Urethane Acrylate Oligomers: Xasaasiyadda Filimada La Daaweeyay ee Iftiinka UV iyo Qoyaanka leh iyo kuwa aan lahayn nuugayaasha UV."
"Dhammaan qaacidooyinka ku salaysan oligomers-ka UA ma muujin wax huruud ah oo isha qaawan ah mana jirin wax huruud ah ama midab beddel ah sida lagu cabbiray spectrophotometer-ka," ayuu yiri Ghaderi. "Oligomers-ka jilicsan ee urethane acrylate waxay muujiyeen xoog jilicsan iyo modulus hoose iyagoo muujinaya dherer sare. Waxqabadka oligomers-ka nus-adag wuxuu ahaa mid dhexe, halka oligomers-ka adag ay keeneen xoog jiidis sare iyo modulus oo leh dherer hoose. Waxaa la arkay in nuugayaasha UV iyo HALS ay farageliyaan daaweynta, natiijadana, isku-xirka filimka la daaweeyay ayaa ka hooseeya kan nidaamka ka maqan labadan."
Qaaciidooyinka Heerka Xiga III
Qaababka Heerka Xiga III waxay soo bandhigeen Joe Lichtenhan oo ka tirsan Hybrid Plastics Inc., kaasoo daboolay "Waxyaabaha lagu daro POSS ee kala firdhinta iyo Xakamaynta Viscosity," muuqaal ahaan waxyaabaha lagu daro POSS, iyo sida loogu tixgelin karo waxyaabaha lagu daro ee isku-dhafka ah ee caqliga badan ee nidaamyada dahaarka.
Lichtenhan waxaa ku xigay Yang ee Evonik, oo bandhiggiisii labaad uu ahaa "Isticmaalka Waxyaabaha lagu daro Silica ee Khadadka Daabacaadda UV."
"Qaabka daaweynta UV/EB, silica lagu daweeyay dusha sare waa badeecada la doorbidayo maadaama xasillooni heer sare ah ay fududaan karto in la gaaro iyadoo la ilaalinayo dheellitir wanaagsan oo loogu talagalay codsiyada daabacaadda," Yang ayaa xusay.
"Xulashada Dahaarka ee UV ee la Daweyn karo ee Codsiyada Gawaarida Gudaha," oo uu qoray Kristy Wagner, Red Spot Paint, ayaa ku xigay.
"Dahaadhka cad ee la daweyn karo ee UV-ga ayaa muujiyay inaysan buuxin oo keliya laakiin ay dhaafsiisan yihiin tilmaamaha adag ee OEM ee hadda jira ee loogu talagalay codsiyada baabuurta gudaha," Wagner ayaa sheegay.
Mike Idacavage, oo ka tirsan Radical Curing LLC, ayaa ku soo xiray "Urethane Oligomers oo leh Viscosity Low Viscosity kuwaas oo u shaqeeya sida Reactive Diluents," kuwaas oo uu xusay in loo isticmaali karo inkjet, buufinta dahaarka iyo codsiyada daabacaadda 3D.
