ʻEkolu mau hālāwai hoʻomaha e hōʻike ana i nā ʻenehana hou loa e hāʻawi ʻia ana ma ke kahua hoʻōla ikehu.
ʻO kekahi o nā mea koʻikoʻi o nā ʻaha kūkā o RadTech nā hālāwai e pili ana i nā ʻenehana hou. MaʻO RadTech 2022, he ʻekolu mau hālāwai i hoʻolaʻa ʻia no nā Formulations Pae Aʻe, me nā noi e kū ana mai ka ʻōpala meaʻai, nā uhi lāʻau, nā uhi kaʻa a me nā mea hou aku.
Nā Hoʻohālikelike Pae Aʻe I
Ua alakaʻi ʻo Bruce Fillipo o Ashland i ka hālāwai Next Level Formulations I me ka "Monomer Impact on Optical Fiber Coatings," kahi nānā ʻana i ka hopena o nā polyfunctionals i nā fiber optical.
"Hiki iā mākou ke loaʻa nā waiwai o ka monomer monofunctional synergistic me nā polyfunctionals - ka hoʻopau ʻana i ka viscosity a me ka hoʻomaikaʻi ʻana i ka solubility," wahi a Filippo. "ʻO ka homogeneity formulation i hoʻomaikaʻi ʻia e hoʻomaʻamaʻa i ka homogeneous crosslinking o nā polyacrylates."
"Ua ana ʻo Vinyl pyrrolidone i nā waiwai maikaʻi loa i hāʻawi ʻia i kahi ʻano fiber optical mua, me ka hoʻopau ʻana i ka viscosity maikaʻi loa, ka elongation kiʻekiʻe a me ka ikaika tensile, a me ka nui o ka hoʻōla ʻana ma mua o a like paha me nā acrylates monofunctional ʻē aʻe i loiloi ʻia," i hoʻohui ʻia ʻo Fillipo. "ʻO nā waiwai i kuhikuhi ʻia i nā uhi fiber optical ua like ia me nā noi UV ʻē aʻe e hiki ke hoʻōla ʻia e like me nā ʻīnika a me nā uhi kūikawā."
Ua ukali ʻo Marcus Hutchins o Allnex me ka "Achieving Ultra-Low Gloss Coatings Through Oligomer Design and Technology." Ua kūkākūkā ʻo Hutchins i nā ala i nā uhi UV 100% me nā mea moena, no ka laʻana no ka lāʻau.
"ʻO nā koho no ka hoʻēmi ʻana i ka ʻōlinolino hou aʻe e komo pū me nā resins me ka hana haʻahaʻa a me ka hoʻomohala ʻana i nā mea hana moena," wahi a Hutchins. "ʻO ka hoʻohaʻahaʻa ʻana i ka ʻōlinolino hiki ke alakaʻi i nā māka marring. Hiki iā ʻoe ke hana i kahi hopena wrinkle ma o ka excimer curing. ʻO ka hoʻonohonoho ʻana i nā lako ke kī i ka hōʻoia ʻana i kahi ʻili laumania me ka ʻole o nā kīnā.
"Ke lilo nei nā hoʻopau haʻahaʻa matte a me nā uhi hana kiʻekiʻe i mea maoli," wahi a Hutchins. "Hiki i nā mea hiki ke ho'ōla ʻia e ka UV ke matte maikaʻi ma o ka hoʻolālā molekala a me ka ʻenehana, e hōʻemi ana i ka nui o nā mea hana moena e pono ai a hoʻomaikaʻi i ke kūpaʻa ʻana i ka burnishing a me ka stain."
A laila ua kamaʻilio ʻo Richard Plenderleith o Sartomer e pili ana i nā "Strategies Toward Reduced Migration Potential in Graphic Arts." Ua kuhikuhi ʻo Plenderleith ma kahi o 70% o nā ʻōpala no ka ʻōpala meaʻai.
Ua hoʻohui ʻo Plenderleith ʻaʻole kūpono nā ʻīnika UV maʻamau no ka hoʻopili ʻana i nā meaʻai pololei, ʻoiai e pono nā ʻīnika UV haʻahaʻa no ka hoʻopili ʻana i nā meaʻai ʻaʻole pololei.
"ʻO ke koho ʻana i nā mea maka i hoʻomaikaʻi ʻia ke kī e hōʻemi i nā pilikia o ka neʻe ʻana," wahi a Plenderleith. "Hiki ke loaʻa nā pilikia mai ka haumia o ka ʻōwili i ka wā o ka paʻi ʻana, nā kukui UV ʻaʻole i hoʻōla pono ʻia, a i ʻole ka neʻe ʻana i ka wā e mālama ʻia ai. ʻO nā ʻōnaehana UV kekahi ʻāpana o ka ulu ʻana o ka ʻoihana ʻōpala meaʻai no ka mea he ʻenehana ia me ka ʻole o ka solvent."
Ua kuhikuhi ʻo Plenderleith e lilo ana i mea paʻakikī ke koi ʻia nā koi o ka hoʻopili ʻana i ka meaʻai.
"ʻIke mākou i kahi neʻe ikaika i ka UV LED, a ʻo ka hoʻomohala ʻana i nā hopena kūpono e hoʻokō ana i nā koi hoʻōla LED ke kī," i hoʻohui ai ʻo ia. "ʻO ka hoʻomaikaʻi ʻana i ka reactivity me ka hōʻemi ʻana i ka neʻe ʻana a me nā pōpilikia e pono ai mākou e hana ma nā photointiators a me nā acrylates."
Ua pani ʻo Camila Baroni o IGM Resins i ka Next Level Formulations I me "The Synergistic Effect of Combinating Aminofunctional Materials with Type I Photoinitiators."
"Mai ka ʻikepili i hōʻike ʻia a hiki i kēia manawa, me he mea lā he mau mea hoʻopale oxygen maikaʻi kekahi o nā amine acrylated a he hiki ke lilo i synergists i ke alo o nā photoinitiators type 1," wahi a Baroni. "ʻO nā amines reactive loa i alakaʻi i ka hopena melemele makemake ʻole ʻia o ke kiʻiʻoniʻoni i hoʻōla ʻia. Ua manaʻo mākou e hiki ke hoʻemi ʻia ka melemele ma o ka hoʻoponopono maikaʻi ʻana i ka ʻike amine acrylated."
Nā Hoʻohālikelike Pae Aʻe II
Ua hoʻomaka ʻo Next Level Formulations II me ka "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 UV crosslinking, SiO2 nanomaterials, nā mea hoʻohui a me ka ʻenehana wax PTFE-free.
"Ke hāʻawi mai nei nā waxes PTFE-free iā mākou i ka hana hoʻohālikelike maikaʻi aʻe i kekahi mau noi, a he 100% biodegradable lākou," i hōʻike ʻia e Laurenti. "Hiki iā ia ke komo i loko o aneane nā ʻano hana uhi."
ʻO ka mea aʻe ʻo Tony Wang o Allnex, nāna i kamaʻilio e pili ana i nā "LED Boosters to Improve Surface Cure by LED for Litho or Flexo Applications."
"Hoʻopau a hoʻopau paha ka pale ʻana o ka oxygen i ka polymerization radical," wahi a Wang. "ʻOi aku ka ʻino i nā uhi lahilahi a haʻahaʻa paha, e like me nā uhi ʻōpala a me nā ʻīnika. Hiki i kēia ke hana i kahi ʻili tacky. ʻOi aku ka paʻakikī o ka hoʻōla ʻana i ka ʻili no ka hoʻōla LED ma muli o ka ikaika haʻahaʻa a me ka laka o ka nalu pōkole."
A laila ua kūkākūkā ʻo Kai Yang o Evonik i ka "Hoʻolaha ʻana i ka hoʻopili ʻana o ka ikehu hiki ke hoʻōla ʻia i ka substrate paʻakikī - Mai kahi ʻano hoʻohui."
"ʻO PDMS (polydimethylsilozanes) ka papa maʻalahi loa o nā siloxanes, a hāʻawi i ka haʻahaʻa loa o ka ʻili a paʻa loa," i ʻike ai ʻo Yang. "Hāʻawi ia i nā waiwai gliding maikaʻi. Ua hoʻomaikaʻi mākou i ka hoʻohālikelike ʻana ma o ka hoʻololi organik, ka mea e kāohi ana i kona hydrophobicity a me ka hydrophilicity. Hiki ke hoʻopilikino ʻia nā waiwai i makemake ʻia e ka loli ʻana o ke ʻano. Ua ʻike mākou ʻoi aku ka maikaʻi o ka polarity i ka solubility i ka matrix UV. Kōkua ʻo TEGO Glide i ka hoʻokele ʻana i nā waiwai o nā siloxanes organomodified, ʻoiai ʻo Tego RAD e hoʻomaikaʻi ana i ka paheʻe a me ka hoʻokuʻu ʻana."
Ua pani ʻo Jason Ghaderi o IGM Resins i ka Next Level Formulations II me kāna haʻiʻōlelo ma "Urethane Acrylate Oligomers: Sensitivity of Cured Films to UV Light and Moisture me a me ka ʻole o UV Absorbers."
"ʻAʻole i hōʻike nā ʻano hana a pau i hoʻokumu ʻia ma nā oligomers UA i ka melemele i ka maka ʻōlohelohe a ʻaneʻane ʻaʻohe melemele a i ʻole ka hoʻololi ʻana e like me ke ana ʻia e ka spectrophotometer," wahi a Ghaderi. "Ua hōʻike nā oligomers urethane acrylate palupalu i ka ikaika tensile haʻahaʻa a me ka modulus i ka wā e hōʻike ana i ka elongation kiʻekiʻe. Aia ka hana oligomers semi-hard ma waena, ʻoiai 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 mea hoʻomoʻa UV a me HALS i ka hoʻōla ʻana, a ma muli o ia mea, ʻoi aku ka haʻahaʻa o ka crosslinking o ka ʻili i hoʻōla ʻia ma mua o ka ʻōnaehana i nele i kēia mau mea ʻelua."
Nā Hoʻohālikelike Pae Aʻe III
Ua hōʻike ʻo Next Level Formulations III iā Joe Lichtenhan o Hybrid Plastics Inc., nāna i uhi i ka "POSS Additives for Dispersion and Viscosity Control," he ʻano e like me nā mea hoʻohui POSS, a pehea e hiki ai ke manaʻo ʻia he mau mea hoʻohui hybrid akamai no nā ʻōnaehana uhi.
Ua ukali ʻia ʻo Lichtenhan e Evonik's Yang, nona ka hōʻike ʻelua ʻo "The Use of Silica Additives in UV Printing Inks."
"I nā ʻano hana hoʻōla UV/EB, ʻo ka silica i mālama ʻia ma ka ʻili ka huahana makemake ʻia no ka mea hiki ke maʻalahi ka hoʻokō ʻana i ke kūpaʻa koʻikoʻi me ka mālama ʻana i ka viscosity maikaʻi no nā noi paʻi," wahi a Yang.
ʻO ka mea aʻe, "Nā Koho Uhi Hiki ke Hoʻōla ʻia e nā UV no nā Hana Kaʻa o loko," na Kristy Wagner, Red Spot Paint.
"Ua hōʻike nā uhi ʻālohilohi a me nā pigmented hiki ke ho'ōla ʻia mai ka UV ʻaʻole wale lākou e hoʻokō akā ʻoi aku hoʻi ma mua o nā kikoʻī koʻikoʻi o ka OEM o kēia manawa no nā noi kaʻa o loko," i ʻōlelo ai ʻo Wagner.
Ua pani ʻo Mike Idacavage, Radical Curing LLC, me nā "Low Viscosity Urethane Oligomers that Function as Reactive Diluents," āna i ʻōlelo ai e hiki ke hoʻohana ʻia i nā noi inkjet, spray coating a me ka paʻi 3D.
