Zaman fashe-fashe guda uku suna nuna sabbin fasahohin da ake bayarwa a fagen warkar da makamashi.
Ɗaya daga cikin abubuwan da suka fi dacewa na taron RadTech shine zaman kan sababbin fasaha. ARadTech 2022, Akwai lokuta uku da aka keɓe don Ƙirar Tsarin Mataki na gaba, tare da aikace-aikacen da suka fito daga marufi na abinci, suturar katako, kayan kwalliyar mota da sauransu.
Na gaba Level Formulations I
Bruce Fillipo na Ashland ya jagoranci Tsarin Tsarin Mataki na gaba na zama na gaba tare da "Tasirin Monomer akan Rufin Fiber Na gani," duban yadda polyfunctionals zai iya yin tasiri ga fiber na gani.
"Za mu iya samun kaddarorin monomer na aiki tare tare da polyfunctionals - danne danko da ingantacciyar narkewa," in ji Filippo. "Ingantacciyar tsari mai kama da juna yana sauƙaƙe haɗin kai na polyacrylates.
"Vinyl pyrrolidone ya auna mafi kyawun kaddarorin da aka ba da su ga tsarin fiber na gani na farko, gami da ingantaccen dankon danko, haɓakar haɓakawa da ƙarfi mai ƙarfi, kuma mafi girma fiye da daidaitaccen maganin warkewa vs sauran acrylates monofunctional da aka kimanta, ”in ji Fillipo. "Kaddarorin da aka yi niyya a cikin suturar fiber na gani sun yi kama da sauran aikace-aikacen da za a iya warkewa ta UV kamar tawada da kayan kwalliya na musamman."
Marcus Hutchins na Allnex ya biyo baya tare da "Samun Rufin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙira ta Oligomer Design da Fasaha." Hutchins sun tattauna hanyoyin zuwa 100% UV coatings tare da matting jamiái, misali ga itace.
Hutchins ya kara da cewa "Zaɓuɓɓuka don ƙarin rage mai sheki sun haɗa da resins tare da ƙananan ayyuka da haɓaka matting wakilai," in ji Hutchins. "Rage sheki na iya haifar da alamar aure. Kuna iya haifar da sakamako mai laushi ta hanyar maganin excimer. Saitin kayan aiki shine mabuɗin don tabbatar da ƙasa mai santsi ba tare da lahani ba.
Hutchins ya kara da cewa "Ƙananan ƙarancin matte da kayan aiki masu girma sun zama gaskiya." "Kayan da za a iya warkewa na UV na iya yin matte da kyau ta hanyar ƙirar ƙwayoyin cuta da fasaha, rage adadin matting ɗin da ake buƙata da haɓaka ƙonawa da juriya."
Richard Plenderleith na Sartomer sannan yayi magana game da "Dabarun Don Rage Ƙirar Ƙaura a Zane-zane." Plenderleith ya yi nuni da cewa kusan kashi 70% na marufi na kayan abinci ne.
Plenderleith ya kara da cewa daidaitattun tawada masu UV ba su dace da marufi na abinci kai tsaye ba, yayin da ana buƙatar ƙananan tawada UV na ƙaura don marufi na abinci kai tsaye.
Plenderleith ya ce "Zaɓin ingantaccen kayan albarkatun ƙasa shine mabuɗin don rage haɗarin ƙaura." “Batutuwa na iya faruwa daga gurɓacewar naɗa yayin bugu, fitilun UV da ba sa warkewa gabaɗaya, ko ƙaura daga ƙaura akan ajiya. Tsarin UV wani ɓangare ne na haɓaka masana'antar tattara kayan abinci saboda fasaha ce mara ƙarfi. "
Plenderleith ya nuna cewa buƙatun buƙatun abinci suna ƙara tsauri.
"Muna ganin motsi mai ƙarfi zuwa UV LED, da kuma haɓaka ingantattun mafita waɗanda ke cika buƙatun warkar da LED shine mabuɗin," in ji shi. "Haɓaka sake kunnawa yayin rage ƙaura da haɗari yana buƙatar mu muyi aiki akan duka masu daukar hoto da acrylates."
Camila Baroni na IGM Resins sun rufe Tsarin Tsarin Mataki na gaba na I tare da "Tasirin Haɗin Haɗin Aminofunctional Materials tare da Nau'in I Photoinitiators."
"Daga bayanan da aka nuna ya zuwa yanzu, yana kama da wasu daga cikin amines acrylated sune masu hana iskar oxygen kuma suna da damar zama masu haɗin gwiwa a gaban nau'in 1 photoinitiators," in ji Baroni. "Mafi yawan amsa amines sun haifar da tasirin launin rawaya maras so na fim ɗin da aka warke. Mun yi tsammanin za a iya rage launin rawaya ta hanyar daidaita abun ciki na acrylated amine. "
Na gaba Level Formulations II
Na gaba Level Formulations II fara da "Ƙananan Barbashi Sizes Pack a Punch: Additive Zaɓuɓɓuka don inganta Surface Performance na UV Coatings Amfani Cross-Linkable, Nanoparticle Dispersions ko Micronized Wax Zabuka," gabatar da Brent Laurenti na BYK Amurka. Laurenti ya tattauna abubuwan da suka hada da UV, SiO2 nanomaterials, additives da fasahar kakin zuma mara amfani da PTFE.
Laurenti ya ruwaito "Waɗanda ba su da PTFE suna ba mu kyakkyawan aiki a wasu aikace-aikacen, kuma suna da 100% biodegradable," in ji Laurenti. "Yana iya shiga kusan kowane tsarin sutura."
Na gaba shi ne Tony Wang na Allnex, wanda yayi magana game da "Masu haɓaka LED don Inganta Cure Surface ta LED don Aikace-aikacen Litho ko Flexo."
Wang ya lura cewa "hawan iskar oxygen yana kashewa ko kuma yana lalata polymerization mai tsattsauran ra'ayi." "Ya fi tsanani a cikin sirara ko ƙarancin ɗanɗano, kamar marufi da tawada. Wannan zai iya haifar da tacky surface. Maganin saman ya fi ƙalubale don maganin LED saboda ƙarancin ƙarfi da kulle ɗan gajeren zango. ”
Daga nan Ki Yang sannan ya tattauna "Inganta makamashi mai da wuya a substrate - daga bangare mai wahala."
"PDMS (polydimethylsilozanes) sune nau'in siloxanes mafi sauƙi, kuma suna samar da ƙananan tashin hankali kuma yana da kwanciyar hankali," Yang ya lura. “Yana ba da kyawawan kaddarorin kyalli. Mun inganta daidaituwa ta hanyar gyare-gyaren kwayoyin halitta, wanda ke sarrafa hydrophobicity da hydrophilicity. Ana iya keɓance kaddarorin da ake so ta hanyar bambancin tsari. Mun gano cewa mafi girma polarity inganta solubility a UV matrix. TEGO Glide yana taimakawa sarrafa kaddarorin siloxanes na organomodified, yayin da Tego RAD yana inganta zamewa da saki. "
Jason Ghaderi na IGM Resins ya rufe Formulations Level II II tare da jawabinsa akan "Urethane Acrylate Oligomers: Sensitivity of Cured Films to UV Light and Danshi tare da kuma ba tare da UV Absorbers."
"Dukkan dabarun da suka danganci UA oligomers ba su nuna launin rawaya ga ido tsirara ba kuma kusan babu launin rawaya ko canza launin kamar yadda aka auna ta hanyar spectrophotometer," in ji Ghaderi. "Urethane acrylate oligomers masu laushi sun nuna ƙarancin ƙarfi da ƙarancin ƙarfi yayin da suke nunawa a cikin tsayin daka. Ayyukan oligomers na Semi-hard ya kasance a tsakiya, yayin da oligomers masu wuya suka haifar da ƙarfin ƙarfi mai ƙarfi da modulus tare da ƙarancin elongation. An lura cewa masu ɗaukar UV da HALS suna tsoma baki tare da maganin, kuma a sakamakon haka, haɗin gwiwar fim ɗin da aka warke ya yi ƙasa da na tsarin da ya rasa waɗannan biyun. "
Na gaba Level Formulations III
Na gaba Level Formulations III featured Joe Lichtenhan na Hybrid Plastics Inc., wanda ya rufe "POSS Additives for Dispersion da danko Control," a matsayin POSS additives, da kuma yadda za a iya la'akari da kaifin baki matasan additives ga coatings tsarin.
Evonik's Yang ya biyo bayan Lichtenhan, wanda gabatarwa na biyu shine "Amfani da Abubuwan Silica Additives a cikin Tawada UV Printing."
"A cikin UV / EB curing formulations, da surface bi da silica ne fĩfĩta samfurin tun da fice kwanciyar hankali zai iya zama da sauki a cimma yayin da rike da kyau danko ga bugu aikace-aikace," Yang ya lura.
"Zaɓuɓɓukan Rufe UV don Aikace-aikacen Mota na Cikin Gida," na Kristy Wagner, Red Spot Paint, ya kasance na gaba.
Wagner ya lura cewa "UV mai iya warkewa bayyananne kuma masu launi sun nuna cewa ba kawai sun hadu ba amma sun wuce ƙayyadaddun ƙayyadaddun bayanan OEM na yanzu don aikace-aikacen kera motoci na ciki," Wagner ya lura.
Mike Idacavage, Radical Curing LLC, an rufe shi da "Ƙananan Dankowa Urethane Oligomers wanda ke Aiki azaman Diluents na Reactive," wanda ya lura ana iya amfani da shi a cikin inkjet, feshin feshi da aikace-aikacen bugu na 3D.
