Izikhathi ezintathu zokuphumula zibonisa ubuchwepheshe bamuva obunikezwayo emkhakheni wokwelapha amandla.
Esinye sezici ezivelele emihlanganweni yeRadTech yimihlangano yobuchwepheshe obusha.I-RadTech 2022, kube nezikhathi ezintathu ezinikezelwe ku-Next Level Formulations, kanye nezinhlelo zokusebenza ezisukela ekupakisheni ukudla, ukumbozwa ngokhuni, ukumbozwa ngezimoto nokuningi.
Amafomula Ezinga Elilandelayo I
UBruce Fillipo wase-Ashland uhole iseshini ye-Next Level Formulations I enesihloko esithi “Monomer Impact on Optical Fiber Coatings,” ebheka ukuthi ama-polyfunctional angathinta kanjani ama-optical fibers.
“Singathola izakhiwo ze-monomer ezisebenza ngokubambisana ezinama-polyfunctional – ukucindezela i-viscosity kanye nokuncibilika okuthuthukisiwe,” kuphawula uFilippo. “Ukwakheka okuthuthukisiwe kwenza kube lula ukuxhumanisa ama-polyacrylates ngendlela efanayo.
“I-Vinyl pyrrolidone ilinganise izakhiwo ezingcono kakhulu ezinikezwe ekwakhiweni kwefayibha yokukhanya eyinhloko, okuhlanganisa ukucindezela okuhle kakhulu kwe-viscosity, ukunwebeka okuphezulu kanye namandla okudonsa, kanye nesilinganiso sokwelapha esikhulu noma esilinganayo uma kuqhathaniswa nezinye i-acrylates ezisebenza ngokusebenza okukodwa ezihlolwe,” kusho uFillipo. “Izakhiwo eziqondiswe ekumbozweni kwefayibha yokukhanya zifana nezinye izinhlelo zokusebenza ezingelapheka ze-UV ezifana noyinki kanye nokumbozwa okukhethekile.”
UMarcus Hutchins we-Allnex walandela ngokuthi “Ukufeza Izimbozo Ezicwebezelayo Eziphansi Kakhulu Ngokusebenzisa Umklamo Nobuchwepheshe be-Oligomer.” UHutchins waxoxa ngezindlela zokufaka izimbozo ze-UV eziyi-100% ngama-matting agents, isibonelo ngokhuni.
“Izinketho zokunciphisa ukukhanya okwengeziwe zifaka phakathi ama-resin anomsebenzi ophansi kanye nokuthuthukisa ama-matting agents,” kusho uHutchins. “Ukwehlisa ukukhanya kungaholela ezimaki ezibolile. Ungakha umphumela wokushwabana ngokusebenzisa i-excimer curing. Ukusetha imishini kuyisihluthulelo sokuqinisekisa ukuthi indawo ebushelelezi ayinazo iziphambeko.
“Ukuqeda okuphansi kwe-matte kanye nokugqoka okuphezulu sekuyinto engokoqobo,” kusho uHutchins. “Izinto eziphulukiswa yi-UV zingaba ne-matte ngempumelelo ngokuklama nobuchwepheshe bama-molecule, kuncishiswe inani lama-matting agents adingekayo futhi kuthuthukiswe ukumelana nokushiswa kanye nokumelana namabala.”
URichard Plenderleith waseSartomer wabe esekhuluma “Ngamasu Okunciphisa Amandla Okufuduka Kwezinto Ezithile Ezobuciko Bezithombe.” UPlenderleith waveza ukuthi cishe u-70% wokupakisha ungowokupakisha ukudla.
UPlenderleith wengeze ngokuthi uyinki ojwayelekile we-UV awufaneleki ekupakisheni ukudla okuqondile, kuyilapho uyinki we-UV ohamba kancane uyadingeka ekupakisheni ukudla okungaqondile.
“Ukukhethwa kwezinto zokusetshenziswa ezilungiselelwe kahle kubalulekile ekunciphiseni izingozi zokufuduka,” kusho uPlenderleith. “Izinkinga zingavela ngenxa yokungcoliswa kwemiqulu ngesikhathi sokuphrinta, izibani ze-UV ezingapholi kuyo yonke indawo, noma ukuqala ukufuduka lapho kugcinwe. Izinhlelo ze-UV ziyingxenye yokukhula kwemboni yokupakisha ukudla njengoba kuwubuchwepheshe obungenazo izinyibilikisi.”
UPlenderleith ukhombe ukuthi izidingo zokupakisha ukudla ziya ngokuya ziba nzima.
“Sibona ukushukuma okunamandla kwe-UV LED, kanye nokuthuthukiswa kwezixazululo ezisebenzayo ezihlangabezana nezidingo zokwelashwa kwe-LED kubalulekile,” enezela. “Ukuthuthukisa ukusabela ngesikhathi esifanayo ngenkathi kunciphisa ukufuduka kanye nezingozi kudinga ukuthi sisebenze kokubili kuma-photointiators kanye nama-acrylates.”
UCamila Baroni we-IGM Resins uvale i-Next Level Formulations I nge-“The Synergistic Effect of Combination Aminofunctional Materials with Type I Photoinitiators.”
“Kusukela kudatha ekhonjisiwe kuze kube manje, kubonakala sengathi amanye ama-amine acrylated ayizivimbeli ezinhle ze-oxygen futhi anamandla okubambisana uma kukhona ama-photoinitiators ohlobo 1,” kusho uBaroni. “Ama-amine asabela kakhulu aholele emphumeleni ongafuneki wokuphuzi wefilimu elaphekile. Sicabange ukuthi ukuphuzi kungancishiswa ngokulungiswa kahle kokuqukethwe kwama-amine acrylated.”
Amafomula Ezinga Elilandelayo II
I-Next Level Formulations II yaqala ngokuthi “Small Particle Sizes Pack a Punch: Additive Options to Improve Surface Performance of UV Coatings Using Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options,” eyethulwe nguBrent Laurenti we-BYK USA. ULaurenti uxoxe ngezithasiselo ze-UV crosslinking, i-SiO2 nanomaterials, izithasiselo kanye nobuchwepheshe be-wax obungena-PTFE.
“Ama-wax angenayo i-PTFE asinika ukusebenza okungcono kokulinganisa kwezinye izinhlelo zokusebenza, futhi abola ngo-100%,” kubika uLaurenti. “Angangena cishe kunoma yiluphi uhlobo lokumboza.”
Okulandelayo kwakunguTony Wang we-Allnex, owakhuluma “ngama-LED Boosters okuthuthukisa i-Surface Cure nge-LED yezinhlelo zokusebenza ze-Litho noma ze-Flexo.”
“Ukuvinjelwa komoya-mpilo kuyacima noma kususe ukwakheka kwe-radical polymerization,” kuphawula uWang. “Kunzima kakhulu ezimbozweni ezincane noma eziphansi ze-viscosity, njengezembozo zokupakisha kanye noyinki. Lokhu kungadala ubuso obunamathelayo. Ukwelashwa kobuso kuyinselele kakhulu ekwelapheni kwe-LED ngenxa yokuqina okuphansi kanye nokukhiya kobude obufushane be-wavelength.”
I-Kai Yang ka-Evonik yabe isixoxa ngesihloko esithi “Ukukhuthaza Ukunamathela Okwelaphayo Kwamandla Esigabeni Esinzima – Kusukela Esicini Sokwengeza.”
“I-PDMS (polydimethylsilozanes) iyisigaba esilula kakhulu sama-siloxanes, futhi inikeza ukucindezeleka okuphansi kakhulu kobuso futhi izinzile kakhulu,” kusho uYang. “Inikeza izakhiwo ezinhle zokushelela. Sithuthukise ukuhambisana ngokuguqulwa kwezinto eziphilayo, okulawula ukungakwazi kwayo ukungena emanzini kanye nokungafinyeleli kwamanzi. Izakhiwo ezifiselekayo zingalungiswa ngokuguquguquka kwesakhiwo. Sithole ukuthi i-polarity ephezulu ithuthukisa ukuncibilika ku-matrix ye-UV. I-TEGO Glide isiza ukulawula izakhiwo zama-siloxanes ahlanganisiwe, kuyilapho i-Tego RAD ithuthukisa ukushelela nokukhululwa.”
UJason Ghaderi we-IGM Resins uvale i-Next Level Formulations II ngenkulumo yakhe ethi “Urethane Acrylate Oligomers: Ukuzwela Kwamafilimu Ahlungiwe Ekukhanyeni Kwe-UV kanye Nomswakama one-UV Absorbers kanye nongenazo.”
“Zonke izinhlobo ezisekelwe kuma-oligomers e-UA azibonisanga ukuphuzi emehlweni futhi cishe azizange zibonise ukuphuzi noma ukushintsha kombala njengoba kulinganiswe yi-spectrophotometer,” kusho uGhaderi. “Ama-oligomers e-acrylate e-urethane athambile abonise amandla aphansi okudonswa kanye ne-modulus ngenkathi ekhombisa ukunwebeka okuphezulu. Ukusebenza kwama-oligomers aqinile kwakuphakathi, kanti ama-oligomers aqinile abangela amandla aphezulu okudonswa kanye ne-modulus enobude obuphansi. Kuqashelwa ukuthi ama-UV absorber kanye ne-HALS kuphazamisa ukwelashwa, futhi ngenxa yalokho, ukuxhumanisa ifilimu ephilisiwe kuphansi kunokwesistimu engenazo lezi ezimbili.”
Amafomula Ezinga Elilandelayo III
I-Next Level Formulations III iveze uJoe Lichtenhan we-Hybrid Plastics Inc., owahlanganisa "Izithasiselo ze-POSS for Dispersion and Viscosity Control," ukubukeka njengezithasiselo ze-POSS, nokuthi zingabhekwa kanjani njengezithasiselo ezihlakaniphile ze-hybrid zezinhlelo zokumboza.
ULichtenhan walandelwa yiYang ka-Evonik, owesibili owabekwa “Ukusetshenziswa Kwezithasiselo Ze-Silica Kuyinki Yokuphrinta Ye-UV.”
“Ezindleleni zokulungisa i-UV/EB, i-silica ephathwe ebusweni iyona ekhethwayo njengoba ukuzinza okuvelele kungaba lula ukukufeza ngenkathi kugcinwa i-viscosity enhle yezinhlelo zokuphrinta,” kuphawula uYang.
“Izinketho Zokumboza Okungalapheki Kwe-UV Zokusetshenziswa Kwezimoto Zangaphakathi,” nguKristy Wagner, iRed Spot Paint, kwaba ngokulandelayo.
“Izimbozo ezicacile nezinombala ezilaphekayo ze-UV zikhombisile ukuthi azigcini nje ngokuhlangabezana kodwa zidlula nezindinganiso eziqinile ze-OEM zamanje zezinhlelo zokusebenza zangaphakathi kwezimoto,” kuphawula uWagner.
UMike Idacavage, we-Radical Curing LLC, uvale nge-“Low Viscosity Urethane Oligomers ezisebenza njenge-Reactive Diluents,” aphawule ukuthi ingasetshenziswa ku-inkjet, i-spray coating kanye nezinhlelo zokusebenza zokuphrinta ze-3D.
