E toru ngā wāhanga whakawātea e whakaatu ana i ngā hangarau hou e tukuna ana i roto i te ao whakaora pūngao.
Ko tētahi o ngā kaupapa matua o ngā huihuinga a RadTech ko ngā wānanga mō ngā hangarau hou.RadTech 2022, e toru ngā wāhanga i whakatapua ki ngā Whakatakotoranga Taumata Panuku, me ngā tono mai i te takai kai, ngā paninga rakau, ngā paninga motuka me te maha atu.
Ngā Whakatakotoranga Taumata Panuku I
Nā Bruce Fillipo o Ashland i ārahi te wāhanga Next Level Formulations I me te kupu "Monomer Impact on Optical Fiber Coatings," he tirohanga ki te pānga o ngā polyfunctionalities ki ngā muka whatu.
"Ka taea e tātou te whiwhi i ngā āhuatanga o te monomer mahi tahi me ngā mahi maha – te pehi i te matotoru me te whakapai ake i te wairewa," te kī a Filippo. "Mā te whakapai ake i te ōritetanga o te hanganga ka āwhina i te hononga ōrite o ngā polyacrylates."
"I inehia e te vinyl pyrrolidone ngā āhuatanga whānui pai rawa atu i tukuna ki te hanganga muka whatu tuatahi, tae atu ki te pehi matotoru pai rawa atu, te roa me te kaha kume pai ake, me te tere whakaora nui ake, rite rānei ki ērā atu acrylate mahi kotahi kua arotakengia," te tāpiri a Fillipo. "He rite ngā āhuatanga e arohia ana ki ngā paninga muka whatu ki ērā atu tono whakaora UV pērā i te waituhi me ngā paninga motuhake."
I whai mai a Marcus Hutchins o Allnex me te tuhinga “Te Whakatutuki i ngā Paninga Kanapa Tino Iti mā te Hoahoa me te Hangarau Oligomer.” I matapakihia e Hutchins ngā huarahi ki ngā paninga UV 100% me ngā mea whāriki, hei tauira mō te rakau.
"Ko ētahi o ngā kōwhiringa mō te whakaiti i te kanapa ko ngā kapia he iti ake te mahi me te whakawhanake i ngā mea whakawhāiti," te tāpiri a Hutchins. "Mā te whakaiti i te kanapa ka puta he tohu kino. Ka taea e koe te hanga i tētahi pānga kita mā te whakamaroke excimer. Ko te whakarite taputapu te mea nui hei whakarite i tētahi mata maeneene, kāore he hapa."
"Kei te tino kitea ngā whakaotinga iti-matte me ngā paninga mahi-teitei," te tāpiri a Hutchins. "Ka taea e ngā rauemi ka taea te whakaora i te UV te matte mā te hoahoa me te hangarau ngota, ka whakaiti i te nui o ngā mea whakakī e hiahiatia ana, ka whakapai ake hoki i te ātete ki te kanapa me te paru."
I kōrero a Richard Plenderleith o Sartomer mō ngā "Rautaki ki te Whakaiti i te Pūmanawa Hekenga i roto i ngā Toi Whakairoiro." I tohu a Plenderleith e 70% o ngā takai he mea hanga ki ngā takai kai.
I tāpiri atu a Plenderleith, kāore e pai ngā waituhi UV paerewa mō ngā takai kai tika, engari e hiahiatia ana ngā waituhi UV iti te hekenga mō ngā takai kai kore tika.
"Ko te whiriwhiri i ngā rauemi mata kua arotauhia te mea nui hei whakaiti i ngā tūponotanga hekenga," te kī a Plenderleith. "Ka puta pea ngā raruraru mai i te poke o te rōra i te wā e tā ana, te kore e maroke o ngā rama UV i te wā katoa, te tīmatanga rānei o te hekenga i te wā e rongoatia ana. Ko ngā pūnaha UV he wāhanga o te tipu o te umanga takai kai nā te mea he hangarau kore-whakarewa."
I kī a Plenderleith kei te kaha haere ngā whakaritenga mō te takai kai.
"E kite ana mātou i tētahi nekehanga kaha ki te UV LED, ā, ko te whakawhanake i ngā otinga whai hua e tutuki ai ngā whakaritenga whakamaroke LED te mea nui," tāna tāpiri. "Ko te whakapai ake i te tauhohenga me te whakaiti i te hekenga me ngā tūponotanga me mahi mātou i ngā photointiators me ngā acrylates."
Nā Camila Baroni o IGM Resins i kati te Next Level Formulations I me te kīanga "Te Pānga Tahi o te Whakakotahi i ngā Rauemi Aminofunctional me ngā Kaiwhakaahua Momo I."
"Mai i ngā raraunga kua whakaaturia tae noa mai ki tēnei wā, te āhua nei he pai ngā aukati hāora o ētahi o ngā amine kua whakakārikitia, ā, he kaha anō hoki hei kaiwhakakotahi i te aroaro o ngā kaiwhakaoho whakaahua momo 1," te kī a Baroni. "Nā ngā amine tino tauhohe i hua ake ai te pānga kōwhai kore e hiahiatia o te kiriata kua rongoatia. Kua whakaarohia e mātou ka taea te whakaiti i te kōwhai mā te whakatikatika pai i te ihirangi amine kua whakakārikitia."
Ngā Whakatakotoranga Taumata Panuku II
I tīmata a Next Level Formulations II me te "Small Particle Sizes Pack a Punch: Additive Options to Improve Surface Performance of UV Coatings Utilizing Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options," i tukuna e Brent Laurenti o BYK USA. I kōrero a Laurenti mō ngā tāpiringa UV crosslinking, ngā nanomaterials SiO2, ngā tāpiringa me te hangarau ware pi kore-PTFE.
"Kei te pai ake te mahi whakaōrite a ngā ware pi kore-PTFE i ētahi whakamahinga, ā, he pirau 100%," te pūrongo a Laurenti. "Ka taea te whakamahi ki te nuinga o ngā momo paninga."
Ko Tony Wang o Allnex te kaikōrero i muri mai, nāna i kōrero mō "Ngā Whakakaha LED hei Whakapai ake i te Whakaora Mata mā te LED mō ngā Taupānga Litho, Flexo rānei."
"Ka tinei, ka whakakore rānei te aukati hāora i te whakapūhuitanga matū," te kī a Wang. "He kino ake tēnei i roto i ngā paninga angiangi, iti rānei te matotoru, pērā i ngā paninga takai me ngā waituhi. Ka taea e tēnei te hanga i tētahi mata piri. He uaua ake te whakamaroke mata mō te whakamaroke LED nā te iti o te kaha me te raka o te roanga ngaru poto."
Kātahi ka kōrero a Kai Yang o Evonik mō te kaupapa “Te Whakatairanga i te Piritanga Pūngao ka Taea te Whakaora ki te Papa Uaua – Mai i te Āhua Tāpiri.”
"Ko te PDMS (polydimethylsilozanes) te momo siloxanes māmā rawa atu, ā, he iti rawa te taumahatanga o te mata, ā, he tino pumau," te kitenga a Yang. "He pai ngā āhuatanga reti. I whakapai ake mātou i te hototahitanga mā te whakarerekētanga rauropi, e whakahaere ana i tōna hydrophobicity me tōna hydrophilicity. Ka taea te whakarite i ngā āhuatanga e hiahiatia ana mā te rerekētanga hanganga. I kitea e mātou ko te polarity teitei ake ka whakapai ake i te wairewatanga i roto i te matrix UV. Ka āwhina a TEGO Glide ki te whakahaere i ngā āhuatanga o ngā siloxanes kua whakarerekētia, ko Tego RAD ia ka whakapai ake i te paheke me te tukunga."
Nā Jason Ghaderi o IGM Resins i kati te Next Level Formulations II me tana kauhau mō "Urethane Acrylate Oligomers: Te aro o ngā kiriata kua whakamaroketia ki te mārama UV me te makuku me te kore he UV Absorbers."
"Ko ngā tātai katoa i runga i ngā oligomer UA kāore i whakaatu i te kōwhai ki te kanohi tahanga, ā, kāore rawa he kōwhai, he rerekētanga rānei i te inenga e te inenga," te kī a Ghaderi. "Ko ngā oligomer urethane acrylate ngohengohe i whakaatu i te kaha kume iti me te modulus i te mea e whakaatu ana i te roa teitei. Ko te mahi a ngā oligomer haurua-mārō i waenganui, ko ngā oligomer mārō i hua ake he kaha kume teitei me te modulus me te roa iti. E kitea ana ko ngā ngongo UV me ngā HALS e whakararuraru ana i te whakaora, ā, ko te mutunga, he iti ake te hononga whakawhiti o te kiriata whakaora i tērā o te pūnaha kāore i a rātou ēnei e rua."
Ngā Whakatakotoranga Taumata Panuku III
I roto i te Next Level Formulations III, i whakaatuhia a Joe Lichtenhan o Hybrid Plastics Inc., nāna i kōrero mō "POSS Additives for Dispersion and Viscosity Control," he tirohanga hei tāpiringa POSS, me pēhea te whakaaro he tāpiringa ranu atamai mō ngā pūnaha paninga.
I whai mai a Yang a Evonik i Lichtenhan, ko tana whakaaturanga tuarua ko "Te Whakamahinga o ngā Tāpiri Silica i roto i ngā Waituhi Tā UV."
"I roto i ngā whakatakotoranga whakamaroke UV/EB, ko te silica i tukatukahia ki te mata te hua e pai ana, nā te mea he māmā ake te whakatutuki i te pumau tino pai me te pupuri tonu i te matotoru pai mō ngā tono tā," te kī a Yang.
Ko te tuhinga i muri mai ko "Ngā Kōwhiringa Paninga UV Whakaora mō ngā Mahi o Roto o ngā Waka," nā Kristy Wagner, Red Spot Paint.
"Kua whakaatuhia e ngā paninga mārama me ngā paninga tae ka taea te whakaora i te kiri UV, ehara i te mea ka tutuki noa i a rātou ngā whakaritenga pakari a te OEM mō ngā tono waka o roto, engari ka hipa atu hoki i a rātou," te kī a Wagner.
I kati a Mike Idacavage, Radical Curing LLC, me ngā kupu "Ngā Oligomer Urethane Matao Iti e Mahi Ana hei Kaiwhakarewa Tauhohe," e ai ki tāna ka taea te whakamahi i tēnei tuhinga i roto i ngā tono inkjet, paninga rehu me te tā 3D.
