E tolu fa'asalalauga e fa'aalia ai tekinolosi aupito lata mai o lo'o ofoina atu i le fa'amalologa malosi.
O se tasi o mea taua o fonotaga a RadTech o sauniga i luga o tekinolosi fou. IRadTech 2022, e tolu sauniga na faʻapitoa i le Next Level Formulations, faʻatasi ai ma talosaga e amata mai i le afifiina o meaʻai, faʻapipiʻi laupapa, faʻapipiʻi taʻavale ma isi mea.
Laasaga e sosoo ai Formulations I
Bruce Fillipo o Ashland na taʻitaʻia le Next Level Formulations I session ma le "Monomer Impact on Optical Fiber Coatings," o se vaʻaiga i le auala e mafai ai e polyfunctional ona aʻafia ai alava mata.
“E mafai ona matou maua se mea fa'ameamea e tasi fa'atasi fa'atasi ma polyfunctional - e taofiofia le viscosity ma fa'aleleia atili le soluble," o le fa'aaliga lea a Filippo. "O le faʻaleleia o le faʻaogaina o le homogeneity e faʻafaigofieina le tutusa o le fesoʻotaʻiga o polyacrylates.
"Vinyl pyrrolidone na fuaina le tele o meatotino tuʻufaʻatasia e tuʻuina atu i se faʻauluina fiber opitika muamua, e aofia ai le taofiofia o le viscosity sili ona lelei, faʻalautele maualuga ma le malosi faʻamalosi, ma sili atu pe tutusa fua faʻamalolo ma isi acrylates monofunctional iloiloga," faʻaopoopo Fillipo. "O meatotino o loʻo faʻatatau i faʻapipiʻi fiber opitika e tutusa ma isi mea e mafai ona togafitia ai le UV e pei o vaitusi ma faʻapitoa faʻapitoa."
Na soso'o ai Marcus Hutchins o Allnex ma le "Ausia le Uila'i Maualalo Uila'i Uila e ala ile Oligomer Design and Technology." Na talanoaina e Hutchins auala i le 100% UV faʻapipiʻi faʻatasi ma mea faʻapipiʻi, mo se faʻataʻitaʻiga mo laupapa.
"O filifiliga mo le faʻaitiitia o le iila e aofia ai resini e maualalo le faʻaogaina ma le atinaʻeina o mea faʻapipiʻi," faʻaopoopo Hutchins. “O le fa'aitiitia o le iila e mafai ona o'o atu ai i fa'ailoga fa'aleaga. E mafai ona e faia se maanuminumi e ala i le fa'amalolo o le excimer. O le fa'atulagaina o meafaigaluega o le ki lea i le fa'amautinoaina o se mea lamolemole e aunoa ma se fa'aletonu.
"O faʻamaʻi matte maualalo ma faʻaofuofu maualuga-faʻatinoina ua avea ma mea moni," faʻaopoopo Hutchins. "O mea e mafai ona faʻaogaina UV e mafai ona faʻafefeteina lelei e ala i le mamanu mole mole ma tekinolosi, faʻaitiitia le aofaʻi o mea faʻapipiʻi e manaʻomia ma faʻaleleia le mumu ma le pisia."
Ona talanoa lea o Richard Plenderleith o Sartomer e uiga i "Taiala agai i le faaitiitia o le gafatia o femalagaiga i Ata Ata." Na faailoa mai e Plenderleith e tusa ma le 70% o afifi e mo le afifiina o meaai.
Fai mai Plenderleith o vaitusi UV masani e le talafeagai mo le afifiina o meaai tuusao, ae o vaitusi UV feoaʻi maualalo e manaʻomia mo le afifiina o meaʻai.
"O le filifilia o mea mataʻina lelei o le ki lea e faʻaitiitia ai lamatiaga o femalagaiga," o le tala lea a Plenderleith. “O fa'afitauli e mafai ona tupu mai le fa'aleagaina o ta'avale a'o lomitusi, lamepa UV e le o malolo i le taimi atoa, po'o le tu'u ese o femalagaiga i luga o le teuina. O faiga o le UV o se vaega o le tuputupu a'e o le gaosiga o mea'ai ona o se tekinolosi e leai se solvent."
Na fa'ailoa e Plenderleith o mea e mana'omia mo le afifiina o mea'ai o lo'o fa'atupula'ia.
"O loʻo matou vaʻai i se gaioiga malosi i le UV LED, ma o le atinaʻeina o fofo lelei e faʻamalieina ai manaʻoga faʻamalolo o le LED o le ki," o lana faʻaopoopo mai lea. "O le faʻaleleia atili o le gaioiga aʻo faʻaitiitia le femalagaaʻi ma lamatiaga e manaʻomia ai ona tatou galulue i luga o photointiators ma acrylates."
Na tapunia e Camila Baroni o le IGM Resins le Next Level Formulations I ma le "The Synergistic Effect of Combining Aminofunctional Materials with Type I Photoinitiators."
"Mai faʻamatalaga o loʻo faʻaalia i le taimi nei, e foliga mai o nisi o amine acrylated o ni faʻamaʻi lelei o le okesene ma e iai le gafatia e avea ma synergists i le i ai o le ituaiga 1 photoinitiators," o le tala lea a Baroni. "O amine sili ona gaoioi na taitai atu ai i aafiaga samasama le manaomia o le ata ua fofoina. Matou te manatu o le samasama e mafai ona faʻaitiitia e ala i le faʻaogaina lelei o mea amine acrylated."
Fuafuaga Laasaga Sosoo II
Na amata le Fa'asologa o Laasaga II i le "Small Particle Sizes Pack a Punch: Additive Options to Improve Surface Performance of UV Coatings Utilizing Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options," na tuuina atu e Brent Laurenti o le BYK USA. Na talanoaina e Laurenti mea faʻapipiʻi fesoʻotaʻiga a le UV, SiO2 nanomaterials, faʻaopoopoga ma le PTFE-free wax technology.
"O waxes e leai se PTFE ua maua ai e i matou le faʻatulagaina lelei o faʻatinoga i nisi o talosaga, ma e 100% e mafai ona faʻaleagaina," o le lipoti lea a Laurenti. "E mafai ona alu i le toetoe lava o soʻo se mea faʻapipiʻiina."
Na sosoo ai ma Tony Wang o Allnex, o le na talanoa e uiga i le "LED Boosters e Faʻaleleia le Faʻaleleia o le Vaʻaia e le LED mo Litho poʻo Flexo Applications."
"O le faʻasaina o le okesene e tineia pe faʻafefe ai le polymerization faʻamalosi," o le tala lea a Wang. "E sili atu ona ogaoga i paʻu manifinifi poʻo le maualalo o le viscosity coatings, e pei o afifi afifi ma vaitusi. E mafai ona fausia ai se tacky luga. O le fofo i luga e sili atu ona luitauina mo LED fofo ona o le maualalo o le malosi ma loka o le galu puupuu.
Ona talanoaina lea e Kai Yang o Evonik "Faʻalauiloaina o le Malosiaga e mafai ona faʻapipiʻi ai le faʻapipiʻi faigata i luga ole laiga - Mai se Itu Faʻaopoopo."
"PDMS (polydimethylsilozanes) o le vasega sili ona faigofie o siloxanes, ma e maua ai le maualalo o le vevesi i luga ole laiga ma e matua mautu," o le matau lea a Yang. "O loʻo ofoina mai ai mea faʻalelei lelei. Matou te faʻaleleia le fesoʻotaʻiga e ala i suiga faʻaletino, lea e pulea ai lona hydrophobicity ma le hydrophilicity. O mea e manaʻomia e mafai ona faʻafetaui i suiga faʻavae. Na matou iloa o le maualuga o le polarity e faʻaleleia ai le solubility i le UV matrix. TEGO Glide fesoasoani i le puleaina o meatotino o siloxanes organomodified, aʻo Tego RAD faʻaleleia le paʻu ma le faʻamalolo.
Na tapunia e Jason Ghaderi o le IGM Resins le Next Level Formulations II i lana lauga i luga o le "Urethane Acrylate Oligomers: Maaleale o Ata Vaʻaia i le UV Light ma le Susū ma e aunoa ma le UV Absorbers."
"O fua faʻatatau uma e faʻavae i luga ole UA oligomers na faʻaalia le leai o se samasama ile mata le lava ma toetoe a leai se samasama poʻo se lanu e pei ona fuaina e le spectrophotometer," o le tala lea a Ghaderi. "Oligomers urethane acrylate vaivai na faʻaalia ai le maualalo o le malosi ma le modulus aʻo faʻaalia i le maualuga.
Fuafuaga Laasaga Sosoo III
O le Next Level Formulations III na fa'aalia ai Joe Lichtenhan o Hybrid Plastics Inc., o ia na ufiufi "POSS Additives for Dispersion and Viscosity Control," o se foliga o POSS additives, ma le auala e mafai ai ona manatu o latou mea faʻapipiʻi faʻapipiʻi atamai mo faiga faʻapipiʻi.
Na sosoo ai ma Lichtenhan e le Evonik's Yang, o lana folasaga lona lua "O le Faʻaaogaina o Silica Additives i UV Printing Inks."
"I le UV / EB curing formulations, o le silica e togafitia i luga o le mea e sili ona lelei ona o le mautu tulaga ese e mafai ona faigofie ona ausia aʻo tumau pea le viscosity lelei mo le lolomiina o talosaga," o le tala lea a Yang.
“UV Curable Coating Options for Interior Automotive Applications,” saunia e Kristy Wagner, Red Spot Paint, na sosoo ai.
“UV e mafai ona togafitia ma paʻu paʻu ua faʻaalia e le gata ina latou fetaui ae sili atu i le taimi nei o faʻamatalaga faʻamaonia a le OEM mo mea tau taʻavale i totonu," o le tala lea a Wagner.
Mike Idacavage, Radical Curing LLC, tapunia i le "Low Viscosity Urethane Oligomers that Function as Reactive Diluents," lea na ia taʻua e mafai ona faʻaaogaina i inkjet, spray coating ma 3D lomitusi talosaga.
