Magawo atatu oyambira akuwonetsa ukadaulo waposachedwa womwe ukuperekedwa m'munda wokonza mphamvu.
Chimodzi mwa zinthu zofunika kwambiri pa misonkhano ya RadTech ndi misonkhano yokhudza ukadaulo watsopano.RadTech 2022, panali magawo atatu odzipereka ku Next Level Formulations, ndi ntchito kuyambira kulongedza chakudya, zokutira zamatabwa, zokutira zamagalimoto ndi zina zambiri.
Mafomula Otsatira I
Bruce Fillipo wa ku Ashland adatsogolera gawo la Next Level Formulations I ndi "Monomer Impact on Optical Fiber Coatings," kuwunika momwe ma polyfunctional angakhudzire ulusi wa kuwala.
"Tikhoza kupeza mawonekedwe a monomer omwe amagwira ntchito limodzi ndi polyfunctionals - kuchepetsa kukhuthala kwa viscosity ndi kusungunuka bwino," Filippo adatero. "Kukhala bwino kwa kapangidwe kameneka kumathandiza kuti polyacrylates zigwirizane bwino.
"Vinyl pyrrolidone anayeza makhalidwe abwino kwambiri omwe amaperekedwa ku kapangidwe ka ulusi wowala, kuphatikizapo kupondereza kwabwino kwambiri kwa kukhuthala, kutalika kwapamwamba komanso mphamvu yokoka, komanso kuchuluka kwa kuchiritsa kofanana kapena kofanana poyerekeza ndi ma acrylates ena ogwiritsidwa ntchito limodzi," adawonjezera Fillipo. "Makhalidwe omwe amagwiritsidwa ntchito mu utoto wowala ndi ofanana ndi ntchito zina zochiritsira za UV monga inki ndi utoto wapadera."
Marcus Hutchins wa Allnex adatsatira ndi "Kukwaniritsa Zophimba Zowala Kwambiri Kudzera mu Kapangidwe ndi Ukadaulo wa Oligomer." Hutchins adakambirana njira zopezera zophimba za UV 100% pogwiritsa ntchito zophimba, mwachitsanzo zamatabwa.
"Njira zina zochepetsera kunyezimira zikuphatikizapo ma resin omwe amagwira ntchito yochepa komanso kupanga zinthu zomatira," anawonjezera Hutchins. "Kuchepetsa kunyezimira kungayambitse zizindikiro zowononga. Mutha kupanga makwinya pogwiritsa ntchito excimer curing. Kukhazikitsa zida ndikofunikira kwambiri kuti malo osalala azikhala opanda zolakwika.
"Zovala zopepuka komanso zopaka bwino kwambiri zikuyamba kuoneka," anawonjezera Hutchins. "Zipangizo zochiritsika za UV zimatha kupangidwa bwino kudzera mu kapangidwe ka mamolekyulu ndi ukadaulo, kuchepetsa kuchuluka kwa zinthu zofunikira pa matiresi ndikuwonjezera kukana kuyaka ndi madontho."
Kenako Richard Plenderleith wa ku Sartomer analankhula za “Njira Zochepetsera Kusamuka kwa Anthu mu Zaluso Zojambula.” Plenderleith ananena kuti pafupifupi 70% ya mapepala opakidwa ndi chakudya.
Plenderleith adawonjezera kuti inki yodziwika bwino ya UV si yoyenera kulongedza chakudya mwachindunji, pomwe inki yotsika ya UV imafunika polongedza chakudya mwachindunji.
"Kusankha zipangizo zopangira zabwino kwambiri ndikofunikira kwambiri pochepetsa chiopsezo cha kusamuka," anatero Plenderleith. "Mavuto angabwere chifukwa cha kuipitsidwa kwa mipukutu panthawi yosindikiza, nyali za UV zomwe sizimauma nthawi zonse, kapena kusamuka kukasungidwa. Makina a UV ndi gawo la kukula kwa makampani opangira chakudya chifukwa ndi ukadaulo wopanda zosungunulira."
Plenderleith adanenanso kuti zofunikira pakulongedza chakudya zikukulirakulira.
"Tikuwona kusintha kwakukulu kwa kuwala kwa UV, ndipo kupanga njira zogwirira ntchito bwino zomwe zikukwaniritsa zofunikira pakuchiritsa kwa LED ndikofunikira," adatero. "Kukonza njira zogwirira ntchito komanso kuchepetsa kusamuka ndi zoopsa kumafuna kuti tigwire ntchito pa ma photointiators ndi ma acrylates."
Camila Baroni wa IGM Resins anatseka Next Level Formulations I ndi "The Synergistic Effect of Combination Aminofunctional Materials with Type I Photoinitiators."
"Kuchokera pa deta yomwe yawonetsedwa mpaka pano, zikuwoneka kuti ma amine ena a acrylated ndi abwino oletsa mpweya ndipo amatha kugwira ntchito limodzi ngati pali ma photoinitiator amtundu woyamba," adatero Baroni. "Ma amine omwe amagwira ntchito kwambiri adapangitsa kuti filimu yochiritsidwayo isinthe kukhala yachikasu. Taganiza kuti chikasucho chingachepe posintha kuchuluka kwa ma amine a acrylated."
Mafomula Otsatira II
Zotsatira Zachiwiri Za Gawo Lachiwiri zinayamba ndi “Small Particle Sizes Pack a Punch: Additive Options to Improve Surface Performance of UV Coatings Using Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options,” zomwe zinaperekedwa ndi Brent Laurenti wa BYK USA. Laurenti anakambirana zowonjezera za UV crosslinking, SiO2 nanomaterials, zowonjezera ndi ukadaulo wa sera wopanda PTFE.
"Ma sera opanda PTFE akutipatsa magwiridwe antchito abwino kwambiri pa ntchito zina, ndipo amatha kuwola 100%," adatero Laurenti. "Atha kugwiritsidwa ntchito pafupifupi mu njira iliyonse yophikira."
Wotsatira anali Tony Wang wa Allnex, yemwe adalankhula za "Zowonjezera za LED kuti Zikonze Kuchiritsa kwa Pamwamba ndi LED pa Mapulogalamu a Litho kapena Flexo."
“Kuletsa mpweya wa okosijeni kumazimitsa kapena kuchotsa polymerization ya radical,” adatero Wang. “Kumakhala koopsa kwambiri mu zophimba zopyapyala kapena zochepa, monga zophimba zopaka ndi inki. Izi zingapangitse pamwamba kukhala paubweya womata. Kuchiritsa pamwamba kumakhala kovuta kwambiri pa kuchiritsa kwa LED chifukwa cha mphamvu yochepa komanso kutsekeka kwa kutalika kwa mafunde afupi.”
Kenako Kai Yang wa Evonik adakambirana za "Kulimbikitsa Kumamatira Kwamphamvu Kochiritsika ku Substrate Yovuta - Kuchokera ku Mbali Yowonjezera."
“PDMS (polydimethylsilozanes) ndi gulu losavuta kwambiri la ma siloxanes, ndipo amapereka mphamvu yochepa kwambiri pamwamba ndipo ndi yokhazikika kwambiri,” adatero Yang. “Imapereka mphamvu zabwino zoyenda. Tasintha kuyanjana ndi kusintha kwachilengedwe, komwe kumawongolera kusagwirizana kwake ndi madzi ndi kusinthasintha kwake. Zinthu zomwe zimafunidwa zitha kusinthidwa ndi kusintha kwa kapangidwe kake. Tapeza kuti polarity yapamwamba imakulitsa kusungunuka mu UV matrix. TEGO Glide imathandiza kuwongolera mphamvu za ma siloxanes opangidwa ndi organomodified, pomwe Tego RAD imakulitsa kutsetsereka ndi kumasulidwa.”
Jason Ghaderi wa IGM Resins anatseka Next Level Formulations II ndi nkhani yake yokhudza “Urethane Acrylate Oligomers: Kuzindikira Mafilimu Ochiritsidwa ku UV Light ndi Chinyezi chokhala ndi UV Absorbers komanso chopanda.”
"Mafomula onse ozikidwa pa ma oligomer a UA sanawonetse chikasu m'maso ndipo sanawonetse chikasu kapena kusintha mtundu monga momwe adayesedwera ndi spectrophotometer," adatero Ghaderi. "Ma oligomer ofewa a urethane acrylate anali ndi mphamvu yochepa yogwira ntchito komanso modulus pomwe anali ndi kutalika kwakukulu. Kuchita bwino kwa ma oligomer okhazikika kunali pakati, pomwe ma oligomer olimba anali ndi mphamvu yayikulu yogwira ntchito komanso modulus yokhala ndi kutalika kochepa. Zawonedwa kuti ma UV absorbers ndi HALS zimasokoneza kuchira, ndipo chifukwa chake, kulumikizana kwa filimu yochiritsidwa kumakhala kotsika kuposa kwa makina omwe alibe awiriwa."
Mafomula Otsatira III
Next Level Formulations III inali ndi Joe Lichtenhan wa Hybrid Plastics Inc., yemwe adalemba za "POSS Additives for Dispersion and Viscosity Control," mawonekedwe ngati zowonjezera za POSS, ndi momwe zingawonedwe ngati zowonjezera zanzeru zosakanikirana pamakina ophikira.
Pambuyo pa Lichtenhan kunatsatiridwa ndi Yang wa Evonik, yemwe nkhani yake yachiwiri inali "Kugwiritsa Ntchito Zowonjezera za Silika mu Inki Zosindikizira za UV."
"Mu njira zophikira za UV/EB, silika yothiridwa pamwamba ndiye chinthu chomwe chimakondedwa kwambiri chifukwa kukhazikika kwabwino kungakhale kosavuta kupeza pamene mukusunga kukhuthala kwabwino kwa ntchito zosindikizira," adatero Yang.
"Zosankha Zophimba UV Zochiritsika Pakugwiritsa Ntchito Magalimoto Amkati," lolembedwa ndi Kristy Wagner, Red Spot Paint, linali lotsatira.
"Zophimba zoyera komanso zofiirira zomwe zimachiritsidwa ndi UV zasonyeza kuti sizimangokwaniritsa zofunikira za OEM pakugwiritsa ntchito magalimoto mkati," adatero Wagner.
Mike Idacavage, wa Radical Curing LLC, watseka ndi "Low Viscosity Urethane Oligomers yomwe imagwira ntchito ngati Reactive Diluents," zomwe adanenanso kuti zitha kugwiritsidwa ntchito mu inkjet, spray coating ndi 3D printing applications.
