Hōʻike ʻia ʻekolu mau wā hoʻomaha i nā ʻenehana hou loa i hāʻawi ʻia i ke kahua hoʻōla ikehu.
ʻO kekahi o nā mea koʻikoʻi o nā hālāwai kūkā o RadTech ʻo ia nā kau ma nā ʻenehana hou. Ma kaʻO RadTech 2022, he 'ekolu mau kau i ho'ola'a 'ia no ka Next Level Formulations, me nā noi mai ka ho'opili 'ai mea'ai, ka uhi lā'au, nā ka'a ka'a a me nā mea hou aku.

Ua alakaʻi ʻo Bruce Fillipo o Ashland i ka hui Next Level Formulations I me "Monomer Impact on Optical Fiber Coatings," e nānā i ka hopena o nā polyfunctional i nā fiber optical.
"Hiki iā mākou ke loaʻa i nā waiwai monomer synergistic monofunctional me nā polyfunctionals - ka hoʻopau ʻana i ka viscosity a me ka hoʻomaikaʻi ʻana i ka solubility," wahi a Filippo. "ʻO ka hoʻonui ʻana i ka homogeneity e hoʻomaʻamaʻa i ka crosslinking homogeneous o polyacrylates.
"Ua ana ʻo Vinyl pyrrolidone i nā waiwai holoʻokoʻa maikaʻi loa i hāʻawi ʻia i ka hoʻokumu ʻana o ka fiber optical mua, me ka hoʻopau ʻana i ka viscosity maikaʻi, ka elongation kiʻekiʻe a me ka ikaika tensile, a ʻoi aku ka nui o ka lāʻau lapaʻau ma mua o nā acrylates monofunctional i loiloi ʻia," wahi a Fillipo. "ʻO nā waiwai i manaʻo ʻia i loko o nā uhi fiber optical e like me nā noi hoʻōla UV ʻē aʻe e like me nā inika a me nā uhi kūikawā."
Ua ukali ʻo Marcus Hutchins o Allnex me ka "Achieving Ultra-Low Gloss Coatings Through Oligomer Design and Technology." Kūkākūkā ʻo Hutchins i nā ala e hiki ai i ka 100% UV coatings me nā mea moena, no ka laʻana no ka lāʻau.
"ʻO nā koho no ka hōʻemi hou ʻana i ka nani e komo pū me nā resins me ka haʻahaʻa haʻahaʻa a me ka hoʻomohala ʻana i nā mea matting," i hoʻohui ʻia ʻo Hutchins. "ʻO ka hoʻohaʻahaʻa ʻana i ka ʻālohilohi hiki ke alakaʻi i nā hōʻailona marring. Hiki iā ʻoe ke hana i kahi hopena wrinkle ma o ka excimer curing. ʻO ka hoʻonohonoho ʻana i nā mea hana he kī ia e hōʻoia i ka ʻili maʻemaʻe me ka ʻole o nā hemahema.
"ʻO ka hoʻopau matte haʻahaʻa a me nā pale hana kiʻekiʻe e lilo i mea ʻoiaʻiʻo," i hoʻohui ʻia ʻo Hutchins. "Hiki i nā mea hiki ke mālama ʻia ka UV ma o ka hoʻolālā mole a me ka ʻenehana, e hōʻemi ana i ka nui o nā mea matting e pono ai a me ka hoʻomaikaʻi ʻana i ka wela a me ka pale ʻana."
Ua kamaʻilio ʻo Richard Plenderleith o Sartomer e pili ana i ka "Strategies Toward Reduced Migration Potential in Graphic Arts." Ua kuhikuhi ʻo Plenderleith e pili ana i ka 70% o ka ʻeke no ka ʻeke meaʻai.
Ua hoʻohui ʻo Plenderleith, ʻaʻole kūpono nā inika UV maʻamau no ka hoʻopili ʻana i ka meaʻai pololei, ʻoiai ʻo nā inika UV neʻe haʻahaʻa e koi ʻia no ka ʻeke meaʻai ʻole.
"ʻO ke koho ʻana i nā mea maka i hoʻopaʻa ʻia he kī nui e hōʻemi i ka pilikia o ka neʻe ʻana," wahi a Plenderleith. "Hiki nā pilikia mai ka ʻōwili ʻia ʻana i ka wā paʻi ʻana, ʻaʻole hoʻōla nā kukui UV a i ʻole ka neʻe ʻana i ka neʻe ʻana ma ka waiho ʻana. ʻO nā ʻōnaehana UV kahi ʻāpana o ka ulu ʻana o ka ʻoihana ʻai meaʻai no ka mea he ʻenehana manuahi ʻole.
Ua kuhikuhi ʻo Plenderleith e ʻoi aku ka paʻakikī o nā koi ʻana i nā meaʻai.
"Ke ʻike nei mākou i kahi neʻe ikaika i ka UV LED, a ʻo ka hoʻomohala ʻana i nā hopena kūpono e hoʻokō ai i nā koi curing LED ke kī," i hoʻohui ai ʻo ia. "ʻO ka hoʻomaikaʻi ʻana i ka reactivity ʻoiai e hōʻemi ana i ka neʻe ʻana a me nā pōʻino pono mākou e hana ma nā photointiators a me nā acrylates."
Ua pani ʻia ʻo Camila Baroni o IGM Resins i ka Next Level Formulations I me "The Synergistic Effect of Combining Aminofunctional Materials with Type I Photoinitiators."
"Mai ka ʻikepili i hōʻike ʻia a hiki i kēia manawa, ʻike ʻia kekahi o nā amine acrylated he mau mea hoʻopiʻi oxygen maikaʻi a loaʻa iā ia ka mea hiki ke hana synergists i mua o ke ʻano 1 photoinitiators," wahi a Baroni. "ʻO nā amine reactive i alakaʻi i ka hopena melemele makemake ʻole o ka kiʻiʻoniʻoni hoʻōla. Ua manaʻo mākou e hiki ke hōʻemi ʻia ka melemele ma o ka hoʻoponopono maikaʻi ʻana i ka ʻike amine acrylated.
Nā Papa Hana Hou II
Ua hoʻomaka nā Formulations II aʻe me "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 hōʻike ʻia e Brent Laurenti o BYK USA. Ua kūkākūkā ʻo Laurenti i nā mea hoʻohui hoʻohui UV crosslinking, SiO2 nanomaterials, additives a me ka ʻenehana wax PTFE-free.
"Ke hāʻawi nei nā waxes PTFE-free iā mākou i ka hana hoʻohālikelike ʻoi aku ka maikaʻi ma kekahi mau noi, a he 100% biodegradable lākou," i hōʻike ai ʻo Laurenti. "Hiki iā ia ke komo i loko o nā ʻano hoʻohālikelike ʻia."
Ma hope aʻe ʻo Tony Wang o Allnex, nāna i kamaʻilio e pili ana i "LED Boosters e hoʻomaikaʻi i ka Surface Cure e LED no Litho a i ʻole Flexo Applications."
"Hoʻopiʻi ʻo Oxygen inhibition a i ʻole scavenges radical polymerization," wahi a Wang. "ʻOi aku ka paʻakikī i nā ʻāpana viscosity lahilahi a haʻahaʻa paha, e like me ka uhi ʻana a me nā inika. Hiki i kēia ke hana i kahi ʻili ʻili. ʻOi aku ka paʻakikī o ka lāʻau lapaʻau no ka lāʻau LED ma muli o ka haʻahaʻa haʻahaʻa a me ka laka o ka nalu pōkole.
Ua kūkākūkā ʻo Kai Yang o Evonik i ka "Hoʻolaha ʻana i ka hoʻopili ʻana i ka ikehu Curable Adhesion i ka substrate paʻakikī - mai kahi ʻano hoʻohui."
"ʻO PDMS (polydimethylsilozanes) ka papa maʻalahi o nā siloxanes, a hāʻawi i ka haʻahaʻa haʻahaʻa o ka ʻili a paʻa loa," i ʻike ai ʻo Yang. Hāʻawi ia i nā waiwai lele maikaʻi. Ua hoʻomaikaʻi mākou i ka hoʻohālikelike ʻana ma o ka hoʻololi kūlohelohe, nāna e hoʻomalu i kona hydrophobicity a me ka hydrophilicity. Hiki ke hoʻololi ʻia nā waiwai i makemake ʻia e ka hoʻololi ʻana o ke ʻano. Ua ʻike mākou ua hoʻomaikaʻi ka polarity kiʻekiʻe i ka solubility i ka matrix UV. Kōkua ʻo TEGO Glide i ka mālama ʻana i nā waiwai o nā siloxanes organomodified, ʻoiai ʻo Tego RAD e hoʻomaikaʻi i ka paheʻe a hoʻokuʻu.
Ua pani ʻo Jason Ghaderi o IGM Resins i ka Next Level Formulations II me kāna kamaʻilio ma "Urethane Acrylate Oligomers: Sensitivity of Cured Films to UV Light and Moisture me a me ka ʻole o nā UV Absorbers."
"ʻAʻole i hōʻike ʻia nā ʻōkuhi āpau e pili ana i ka UA oligomers i ka melemele i ka maka ʻōlohelohe a aneane ʻaʻohe melemele a i ʻole ka ʻulaʻula e like me ke ana ʻana e ka spectrophotometer," wahi a Ghaderi. "Ua hōʻike ka soft urethane acrylate oligomers i ka ikaika tensile haʻahaʻa a me ka modulus i ka wā e hōʻike ana i ka elongation kiʻekiʻe. ʻO ka hana oligomers Semi-paʻakikī i waena, akā ʻo nā oligomers paʻakikī i hopena i ka ikaika tensile kiʻekiʻe a me ka modulus me ka elongation haʻahaʻa. Ua ʻike ʻia ua hoʻopilikia nā UV absorbers a me HALS i ka lāʻau, a ʻo ka hopena, ʻoi aku ka haʻahaʻa o ka crosslinking o nā kiʻiʻoniʻoni i hoʻōla ʻia ma mua o ka ʻōnaehana i nele i kēia mau mea ʻelua.
Nā Papa Hana Hou III
Next Level Formulations III ua hōʻike ʻia ʻo Joe Lichtenhan o Hybrid Plastics Inc., nāna i uhi i ka "POSS Additives for Dispersion and Viscosity Control," he ʻano like me POSS additives, a pehea lākou e manaʻo ʻia ai nā mea hoʻohui hybrid akamai no nā ʻōnaehana pale.
Ua ukali ʻia ʻo Lichtenhan e Evonik's Yang, nona ka lua o ka hōʻike ʻana ʻo "The Use of Silica Additives in UV Printing Inks."
"Ma nā hana hoʻoponopono UV / EB, ʻo ka silica i mālama ʻia i ka ʻili ka mea i makemake ʻia no ka mea ʻoi aku ka maʻalahi o ka hoʻokō ʻana me ka mālama ʻana i ka viscosity maikaʻi no ka paʻi ʻana i nā noi," wahi a Yang.
"Nā koho UV Curable Coating no nā noi kaʻa o loko," na Kristy Wagner, Pena ʻulaʻula.
"Ua hōʻike ʻia nā uhi uhi ʻulaʻula a me ka UV curable ʻaʻole lākou e hui wale akā ma mua o nā kikoʻī koʻikoʻi o OEM o kēia manawa no nā noi kaʻa o loko," i ʻike ai ʻo Wagner.
ʻO Mike Idacavage, Radical Curing LLC, i pani ʻia me "Low Viscosity Urethane Oligomers that Function as Reactive Diluents," āna i ʻike ai hiki ke hoʻohana ʻia i ka inkjet, spray coating a me nā noi paʻi 3D.
