Iiseshoni ezintathu zokuphumla zibonisa ubuchwepheshe bamva nje obunikezelwa kwicandelo lokunyanga amandla.
Enye yezona zinto zibalulekileyo kwiingqungquthela zeRadTech ziiseshoni zobuchwepheshe obutsha.I-RadTech 2022, bekukho iiseshoni ezintathu ezinikezelwe kwiNext Level Formulations, kunye nezicelo eziqala ekupakisheni ukutya, ukugqunywa ngomthi, ukugqunywa kweemoto nokunye.
Iifomyula zeNqanaba Elilandelayo I
UBruce Fillipo waseAshland ukhokele iseshoni yeNext Level Formulations I enesihloko esithi “Monomer Impact on Optical Fiber Coatings,” ejonga indlela iipolyfunctional ezinokuthi zichaphazele ngayo ii-optical fibers.
“Singafumana iipropati ze-monomer ezisebenza ngokubambisana ezine-polyfunctionals – ukuncitshiswa kwe-viscosity kunye nokunyibilika okuphuculweyo,” utshilo uFilippo. “Ukuhambelana okuphuculweyo kwefomyula kwenza kube lula ukudibanisa ii-polyacrylates ngendlela efanayo.
“I-Vinyl pyrrolidone ilinganise iipropati ezilungileyo kakhulu ezifakwe kwifomyula yefayibha yokukhanya ephambili, kubandakanya ukuncitshiswa kwe-viscosity egqwesileyo, ukunwebeka okuphezulu kunye namandla okutsalwa, kunye nesantya sokuphilisa esingaphezulu okanye esilinganayo xa kuthelekiswa nezinye ii-acrylates ezisebenza ngokukodwa ezivavanyiweyo,” wongeze watsho uFillipo. “Iimpawu ezijoliswe kwiingubo zefayibha yokukhanya ziyafana nezinye izicelo ze-UV ezinokunyangwa njengee-inki kunye neengubo ezikhethekileyo.”
UMarcus Hutchins wase-Allnex walandela ngo-“Ukufezekisa Iingubo Ezikhazimlayo Eziphantsi Kakhulu Ngokusebenzisa Uyilo kunye neTekhnoloji ye-Oligomer.” UHutchins uxoxe ngeendlela zokufaka iingubo ze-UV eziyi-100% ngee-matting agents, umzekelo, zomthi.
“Iindlela zokunciphisa i-gloss ngakumbi ziquka ii-resin ezingasebenzi kakuhle kunye nokuphuhlisa ii-matting agents,” wongeze watsho uHutchins. “Ukwehlisa i-gloss kunokukhokelela kwiimpawu zokubola. Ungenza isiphumo sokushwabana nge-excimer curing. Ukuseta izixhobo kubalulekile ekuqinisekiseni ukuba umphezulu uthambile ngaphandle kweziphene.
“Iingubo eziphantsi kwe-matte kunye neengubo ezisebenza kakuhle ziya zisenzeka,” wongeze watsho uHutchins. “Izinto ezinyangekayo ze-UV zinokusebenza kakuhle nge-matte ngoyilo lweemolekyuli kunye netekhnoloji, zinciphise ubungakanani bezinto ezifunekayo ze-matting kwaye ziphucule ukutsha kunye nokumelana namabala.”
URichard Plenderleith waseSartomer wathetha “ngeeNdlela zokuNciphisa ukuFuduka kwabantu kwiMifanekiso yoBugcisa.” UPlenderleith wabonisa ukuba malunga ne-70% yempahla epakishiweyo yeyokupakisha ukutya.
UPlenderleith wongeze ngelithi ii-inki ze-UV eziqhelekileyo azifanelekanga ekupakisheni ukutya ngokuthe ngqo, ngelixa ii-inki ze-UV ezifudukayo kancinci ziyafuneka ekupakisheni ukutya okungathanga ngqo.
“Ukukhethwa kwezinto eziluhlaza ezilungiselelweyo kubalulekile ekunciphiseni umngcipheko wokufuduka,” utshilo uPlenderleith. “Iingxaki zinokuvela ngenxa yongcoliseko lwemiqulu ngexesha lokuprinta, izibane ze-UV ezinganyangekiyo, okanye ukufuduka xa zigcinwa. Iinkqubo ze-UV ziyinxalenye yokukhula kweshishini lokupakisha ukutya njengoko bubuchwepheshe obungenazinyibilikisi.”
UPlenderleith ubonise ukuba iimfuno zokupakisha ukutya ziya ziqina ngakumbi.
“Sibona intshukumo enamandla kwi-UV LED, kwaye uphuhliso lwezisombululo ezisebenzayo ezihlangabezana neemfuno zokunyanga i-LED lubalulekile,” wongeze watsho. “Ukuphucula ukusebenza kwakhona ngelixa kunciphisa ukufuduka kunye neengozi kufuna ukuba sisebenze kwi-photointiators kunye ne-acrylates.”
UCamila Baroni we-IGM Resins uvale i-Next Level Formulations I nge-“The Synergistic Effect of Combination Aminofunctional Materials with Type I Photoinitiators.”
“Ukusuka kwidatha ebonisiweyo ukuza kuthi ga ngoku, kubonakala ngathi ezinye zee-amines ze-acrylated zi-inhibitors ezilungileyo ze-oxygen kwaye zinamandla okusebenza ngokubambisana xa kukho ii-photoinitiators zohlobo loku-1,” utshilo uBaroni. “Ezona amines zisabela kakhulu zikhokelele kwisiphumo sokutyheli esingafunekiyo sefilimu ephilisiweyo. Sicinge ukuba ukutyheli kungancitshiswa ngokulungiswa kakuhle komxholo we-amine ye-acrylated.”
Iifomyula zeNqanaba Elilandelayo II
I-Next Level Formulations II yaqala nge-“Small Particle Sizes Pack a Punch: Additive Options to Improve Surface Performance of UV Coatings Using Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options,” eyavezwa nguBrent Laurenti waseBYK USA. ULaurenti uxoxe nge-UV crosslinking additives, i-SiO2 nanomaterials, additives kunye netekhnoloji ye-wax engena-PTFE.
“Ii-wax ezingenayo i-PTFE zisinika ukusebenza okungcono kokulinganisa kwezinye iinkqubo, kwaye ziyabola nge-100%,” utshilo uLaurenti. “Ingangena phantse kuyo nayiphi na indlela yokugquma.”
Okulandelayo yayinguTony Wang we-Allnex, owathetha "ngee-LED Boosters zokuphucula ukuKhanya koMphezulu yi-LED kwizicelo zeLitho okanye zeFlexo."
“Ukuthintelwa kweoksijini kuyayicima okanye kuyisusa i-radical polymerization,” utshilo uWang. “Inzima ngakumbi kwiingubo ezincinci okanye ezithambileyo, ezifana neengubo zokupakisha kunye nee-inki. Oku kunokwenza umphezulu onamathelayo. Unyango lomphezulu lunzima ngakumbi kwi-LED ngenxa yokuqina okuphantsi kunye nokutshixeka kobude obufutshane be-wavelength.”
Emva koko uKai Yang ka-Evonik waxoxa ngesihloko esithi “Ukukhuthaza Amandla Ukunamathela Okunyangekayo kwi-Substrate Enzima – Ukusuka kwi-Aspect Additive.”
“I-PDMS (i-polydimethylsilozanes) lolona hlobo lulula lwee-siloxanes, kwaye zibonelela ngoxinzelelo oluphantsi kakhulu kumphezulu kwaye zizinzile kakhulu,” utshilo uYang. “Inika iipropati ezilungileyo zokutyibilika. Siphucule ukuhambelana ngokuguqulwa kwezinto eziphilayo, okulawula ukunganyamezeli kwamanzi kunye nokunganyeli kwamanzi. Iipropati ezifunwayo zinokulungiswa ngokuguquguquka kwesakhiwo. Sifumanise ukuba i-polarity ephezulu iphucula ukunyibilika kwi-matrix ye-UV. I-TEGO Glide inceda ukulawula iipropati zee-siloxanes ze-organomodified, ngelixa i-Tego RAD iphucula ukutyibilika nokukhululwa.”
UJason Ghaderi we-IGM Resins uvale i-Next Level Formulations II ngentetho yakhe ethi “Urethane Acrylate Oligomers: Uvakalelo lweeFilimu eziPhilisiweyo kwi-UV Light kunye nokufuma kunye nezifunxi ze-UV kunye nezingenazo.”
“Zonke iifomyula ezisekelwe kwi-UA oligomers azibonisanga tyheli emehlweni kwaye azizange zibonakalise tyheli okanye zitshintshe umbala njengoko zilinganiswe yi-spectrophotometer,” utshilo uGhaderi. “I-soft urethane acrylate oligomers zibonise amandla aphantsi okutsalwa kunye ne-modulus ngelixa zibonakala zinde kakhulu. Ukusebenza kwe-semi-hard oligomers bekuphakathi, ngelixa i-hard oligomers zibangele amandla aphezulu okutsalwa kunye ne-modulus enobude obuphantsi. Kuqatshelwe ukuba ii-UV absorbers kunye ne-HALS ziyaphazamisana nonyango, kwaye ngenxa yoko, ukudibanisa ifilimu ephilisiweyo kuphantsi kunenkqubo engenazo ezi zimbini.”
Iifomyula zeNqanaba elilandelayo III
I-Next Level Formulations III yayiquka uJoe Lichtenhan weHybrid Plastics Inc., owathetha nge-"POSS Additives for Dispersion and Viscosity Control," imbonakalo njengezongezo zePOSS, kunye nendlela ezinokuthathwa ngayo njengezongezo ezikrelekrele ze-hybrid kwiinkqubo zokugquma.
ULichtenhan walandelwa nguYang ka-Evonik, owathi intetho yakhe yesibini yayisithi “Ukusetyenziswa kwee-Silica Additives kwi-UV Printing Inks.”
“Kwiifomyula zokunyanga ze-UV/EB, i-silica ephathwe ngomphezulu yeyona mveliso ikhethwayo kuba ukuzinza okugqwesileyo kunokuba lula ukuyifumana ngelixa kugcinwa i-viscosity elungileyo kwizicelo zokuprinta,” utshilo uYang.
“Iindlela zokugquma i-UV eziNyangekayo kwiiNkqubo zeMoto zangaphakathi,” nguKristy Wagner, iRed Spot Paint, yayilandela.
“Iingubo ezicacileyo nezinombala ezinyangekayo ze-UV zibonise ukuba azihlangabezani nje kuphela kodwa zidlula imiqathango engqongqo ye-OEM yangoku yezicelo zangaphakathi zeemoto,” utshilo uWagner.
UMike Idacavage, weRadical Curing LLC, uvale nge-“Low Viscosity Urethane Oligomers ezisebenza njengeReactive Diluents,” awathi zingasetyenziswa kwi-inkjet, kwi-spray coating nakwi-3D printing applications.
