Magawo atatu opumira akuwonetsa matekinoloje aposachedwa omwe akuperekedwa m'munda wochiritsa mphamvu.
Chimodzi mwazabwino kwambiri pamisonkhano ya RadTech ndi magawo aukadaulo watsopano. PaRadTech 2022, panali magawo atatu operekedwa ku Next Level Formulations, ndi ntchito kuyambira kulongedza chakudya, zokutira matabwa, zokutira magalimoto ndi zina.
Next Level Formulations I
Bruce Fillipo waku Ashland adatsogolera gawo la Next Level Formulations I ndi "Monomer Impact on Optical Fiber Coatings," onani momwe ma polyfunctionals angakhudzire ulusi wa kuwala.
"Ife titha kupeza katundu synergistic monofunctional monomer ndi polyfunctionals - mamasukidwe akayendedwe kupondereza ndi bwino solubility," Filippo anati. "Kuwongolera kapangidwe kake kumathandizira kulumikizana kofanana kwa ma polyacrylates.
"Vinyl pyrrolidone anayeza zinthu zabwino kwambiri zomwe zimaperekedwa ku mapangidwe apamwamba a fiber optical, kuphatikizapo kuponderezedwa kwa viscosity, elongation yapamwamba ndi mphamvu zowonongeka, komanso kuchiritsa kwakukulu kapena kofanana ndi ma acrylates ena omwe amayesedwa," anawonjezera Fillipo. "Zinthu zomwe zimayang'aniridwa mu zokutira za fiber optical ndizofanana ndi njira zina zochiritsira za UV monga inki ndi zokutira zapadera."
Marcus Hutchins waku Allnex adatsata "Kukwaniritsa Zovala Zowala Kwambiri Kupyolera mu Oligomer Design and Technology." Hutchins adakambirana njira zofikira 100% zokutira za UV zokhala ndi zomatira, mwachitsanzo zamatabwa.
"Zosankha zochepetsera gloss zina zimaphatikizapo utomoni wokhala ndi magwiridwe antchito ochepa komanso kupanga ma mating," anawonjezera Hutchins. "Kuchepetsa gloss kungayambitse zizindikiro zowononga. Mutha kupanga makwinya pogwiritsa ntchito kuchiritsa kwa excimer. Kuyika zida ndizofunikira kwambiri kuti pakhale malo osalala opanda zolakwika.
"Mapeto otsika a matte ndi zokutira zapamwamba zimakhala zenizeni," anawonjezera Hutchins. "Zinthu zochiritsira za UV zimatha kusakanikirana bwino ndi kapangidwe ka mamolekyu ndi ukadaulo, kuchepetsa kuchuluka kwa zinthu zomwe zimafunikira ndikuwongolera kuyatsa komanso kukana madontho."
Richard Plenderleith wa ku Sartomer ndiye adalankhula za "Njira Zothandizira Kuchepetsa Kusamuka Kwamaluso mu Zojambulajambula." Plenderleith adanenanso kuti pafupifupi 70% yazonyamula ndizonyamula chakudya.
Plenderleith adawonjezeranso kuti ma inki wamba a UV siwoyenera kulongedza chakudya mwachindunji, pomwe ma inki otsika a UV amafunikira pakuyika zakudya zakunja.
"Kusankha zipangizo zokometsera ndizofunikira kuti muchepetse chiopsezo cha kusamuka," adatero Plenderleith. "Nkhani zimatha kuchitika chifukwa choyipitsidwa ndi mipukutu panthawi yosindikiza, nyali za UV zomwe sizimachiritsa ponseponse, kapena kuzimitsa kusuntha posungira. Makina a UV ndi gawo lakukula kwamakampani opanga zakudya chifukwa ndiukadaulo wopanda zosungunulira. ”
Plenderleith adawonetsa kuti zofunikira pakuyika chakudya zikukulirakulira.
"Tikuwona kusuntha kwamphamvu kwa UV LED, ndipo kupanga njira zothanirana ndi machiritso a LED ndikofunikira," adawonjezera. "Kupititsa patsogolo kusinthika ndikuchepetsa kusamuka komanso ngozi kumafuna kuti tigwiritse ntchito ma photointiators ndi ma acrylates."
Camila Baroni wa IGM Resins adatseka Next Level Formulations I ndi "Kugwirizana Kwambiri Pophatikiza Zida Zogwira Ntchito ndi Type I Photoinitiators."
"Kuchokera pazidziwitso zomwe zasonyezedwa mpaka pano, zikuwoneka ngati zina mwa acrylated amines ndi zabwino zoletsa mpweya wa okosijeni ndipo zimatha kukhala synergists pamaso pa mtundu wa 1 photoinitiators," adatero Baroni. "Ma amine omwe amagwira ntchito kwambiri adapangitsa kuti filimu yochiritsidwa ikhale yachikasu. Tikuganiza kuti chikasucho chikhoza kuchepetsedwa pokonza bwino zinthu zomwe zili ndi amine. ”
Next Level Formulations II
Next Level Formulations II idayamba ndi "Kukula Kwapang'ono Pang'onopang'ono: Zosankha Zowonjezera Kuti Mumatsogolere Mawonekedwe Apamwamba a Zovala za UV Pogwiritsa Ntchito Cross-Linkable, Nanoparticle Dispersions kapena Micronized Wax Options," yoperekedwa ndi Brent Laurenti wa BYK USA. Laurenti adakambirana zowonjezera zowonjezera za UV, SiO2 nanomatadium, zowonjezera ndi ukadaulo wa sera wopanda PTFE.
"PTFE-free waxes imatipatsa ife kuchita bwino muzochita zina, ndipo ndi 100% biodegradable," adatero Laurenti. "Itha kulowa mumtundu uliwonse wa zokutira."
Wotsatira anali Tony Wang wa Allnex, yemwe adalankhula za "LED Boosters to Improve Surface Cure by LED for Litho kapena Flexo Applications."
"Kuletsa kwa okosijeni kumathetsa kapena kuwononga ma polymerization," adatero Wang. "Ndizovuta kwambiri pakupaka zopyapyala kapena zowoneka bwino, monga zokutira ndi inki. Izi zitha kupanga malo ovuta. Kuchiritsa kwapamwamba kumakhala kovuta kwambiri pakuchiritsa kwa LED chifukwa chakuchepa kwamphamvu komanso kutsekeka kwa kutalika kwaufupi. ”
Evonik's Kai Yang ndiye adakambilana "Kulimbikitsa Kukhazikika Kwa Mphamvu Zochiritsira Kumagawo Ovuta - Kuchokera ku Mbali Yowonjezera."
"PDMS (polydimethylsilozanes) ndi gulu losavuta kwambiri la siloxanes, ndipo limapereka mphamvu yotsika kwambiri komanso yokhazikika," adatero Yang. "Ili ndi malo abwino otsetsereka. Tinapititsa patsogolo kugwirizanitsa ndi kusintha kwa organic, komwe kumayendetsa hydrophobicity ndi hydrophilicity. Zomwe zimafunidwa zimatha kusinthidwa ndi kusiyanasiyana kwamapangidwe. Tinapeza kuti polarity yapamwamba imapangitsa kusungunuka kwa matrix a UV. TEGO Glide imathandizira kuwongolera ma siloxanes opangidwa ndi organomodified, pomwe Tego RAD imathandizira kutsetsereka ndikumasulidwa.
Jason Ghaderi wa IGM Resins adatseka Next Level Formulations II ndi nkhani yake ya "Urethane Acrylate Oligomers: Sensitivity of Curred Films to UV Light and Moist with and without UV Absorbers."
"Mapangidwe onse otengera UA oligomers sanawonetse chikasu m'maso ndipo alibe chikasu kapena kusinthika monga momwe amayezera ndi spectrophotometer," adatero Ghaderi. "Ma oligomer ofewa a urethane acrylate adawonetsa mphamvu zochepa komanso modulus pomwe akuwonetsa kutalika kwambiri. Kuchita kwa oligomers kolimba kunali pakati, pomwe ma oligomer olimba adapangitsa kuti azikhala ndi mphamvu zolimba komanso modulus yokhala ndi kutalika kochepa. Zikuoneka kuti zoyambukira za UV ndi HALS zimasokoneza machiritso, ndipo chifukwa chake, kulumikizana kwa filimu yochiritsidwa kumakhala kotsika poyerekeza ndi machitidwe omwe alibe ziwirizi. "
Mapangidwe a Next Level III
Next Level Formulations III inali ndi Joe Lichtenhan wa Hybrid Plastics Inc., yemwe adalemba "POSS Additives for Dispersion and Viscosity Control," mawonekedwe ngati zowonjezera za POSS, ndi momwe angatengedwere ngati zowonjezera zanzeru zosakanizidwa zamakina opaka zokutira.
Lichtenhan adatsatiridwa ndi Evonik's Yang, yemwe ulaliki wake wachiwiri unali "Kugwiritsa Ntchito Silica Additives mu UV Printing Inks."
"Mu machiritso a UV / EB, silika wothira pamwamba ndiye chinthu chomwe chimakondedwa chifukwa kukhazikika kwapadera kumatha kukhala kosavuta kukwaniritsa ndikusunga mamasukidwe abwino osindikizira," adatero Yang.
"UV Curable Coating Options for Interior Automotive Applications," wolemba Kristy Wagner, Red Spot Paint, anali wotsatira.
"Zovala zowoneka bwino komanso zamtundu wa UV zawonetsa kuti sizimangokumana koma zimapitilira zomwe OEM ili nazo pamagalimoto amkati," adatero Wagner.
Mike Idacavage, Radical Curing LLC, yotsekedwa ndi "Low Viscosity Urethane Oligomers that Function as Reactive Diluents," yomwe adanena kuti ikhoza kugwiritsidwa ntchito mu inkjet, zokutira zopopera ndi ntchito zosindikizira za 3D.
