Ibiganiro bitatu by'ingenzi bigaragaza ikoranabuhanga rigezweho ritangwa mu rwego rwo kuvura ingufu.
Kimwe mu bintu by'ingenzi mu nama za RadTech ni ibiganiro ku ikoranabuhanga rishya.RadTech 2022, habayeho ibiganiro bitatu byagenewe Next Level Formulations, birimo gupakira ibiryo, gusiga irangi ku biti, gusiga irangi ku modoka n'ibindi.
Uburyo bwo gushushanya ku rwego rukurikira I
Bruce Fillipo wo muri Ashland yayoboye ikiganiro cya Next Level Formulations I gifite umutwe ugira uti “Impact Monomer on Optical Fiber Coatings,” isuzuma uburyo polyfunctionals zishobora kugira ingaruka ku migozi y’urumuri.
Filippo yagize ati: “Twashoboraga kubona imiterere ya monomer ikora neza hamwe n’imikorere ya polyfunctional – kugabanya ubushyuhe no kunoza uburyo bwo gushonga.” “Uburyo bwiza bwo guhuza imiterere y’ibinyabutabire byoroshya guhuza polyacrylates mu buryo bumwe.
Fillipo yongeyeho ati: “Vinyl pyrrolidone yapimye imiterere myiza muri rusange itangwa n’uburyo bwa fibre optique, harimo kugabanya ubukana bwiza, kurekura cyane no gukomera, hamwe n’igipimo cyo kuvura kiri hejuru cyangwa kingana ugereranije n’izindi acrylate zikoreshwa mu buryo bumwe.” “Imiterere ikoreshwa mu gusiga fibre optique isa n’izindi porogaramu zishobora kuvurwa n’imirasire y’urumuri nka wino n’imyambaro yihariye.”
Marcus Hutchins wo muri Allnex yakurikijeho "Kugera ku irangi rinini cyane binyuze mu gishushanyo n'ikoranabuhanga rya Oligomer." Hutchins yaganiriye ku nzira zo gusiga irangi rya UV 100% akoresheje ibikoresho bifasha mu gusiga, urugero nk'ibiti.
Hutchins yongeyeho ati: “Amahitamo yo kugabanya ubushyuhe arimo resins zifite imikorere mike no gukora ibikoresho byo gupfuka.” “Kugabanya ubushyuhe bishobora gutera ibimenyetso byo kwangirika. Ushobora gukora ingaruka zo kwangirika binyuze mu gusukura. Gushyiraho ibikoresho ni ingenzi kugira ngo ubuso bube bwiza nta nenge.
Hutchins yongeyeho ati: “Irangi rito ridafite matte n'amabara meza arimo kuba impamo. Ibikoresho bishobora kuvurwa na UV bishobora kugira matte neza binyuze mu gushushanya na ikoranabuhanga rya molekile, bikagabanya ingano y'ibikoresho bikenera mu matela kandi bikongera ubushobozi bwo gutwika no kurwanya ibara.”
Hanyuma Richard Plenderleith wo muri Sartomer yavuze ku “Ingamba zo kugabanya ubushobozi bwo kwimuka mu buhanzi bushingiye ku mashusho.” Plenderleith yagaragaje ko hafi 70% by'ibipfunyika ari ibyo gupfunyika ibiryo.
Plenderleith yongeyeho ko wino isanzwe ya UV idakwiye gukoreshwa mu gupfunyika ibiryo mu buryo butaziguye, mu gihe wino ya UV idasaba kwimuka cyane mu gupfunyika ibiryo mu buryo butaziguye.
Plenderleith yagize ati: “Guhitamo ibikoresho fatizo byiza ni ingenzi mu kugabanya ibyago byo kwimuka.” “Ibibazo bishobora guterwa no kwanduzwa n’imizingo mu gihe cyo gucapa, amatara ya UV adakira neza, cyangwa se kwimuka mu gihe cyo kubika. Sisitemu za UV ni bimwe mu bigize iterambere ry’inganda zipfunyika ibiribwa kuko ari ikoranabuhanga ridafite solvent.”
Plenderleith yagaragaje ko ibisabwa mu gupfunyika ibiryo birimo kugenda birushaho gukomera.
Yongeyeho ati: “Tubona ko hari intambwe ikomeye iterwa na LED ya UV, kandi iterambere ry’ibisubizo binoze kuzuza ibisabwa mu gupima LED ni ingenzi.” “Kunoza uburyo bwo gukora neza mu gihe tugabanya kwimuka no guteza ibyago bisaba gukora kuri fotointiators na acrylate.”
Camila Baroni wo muri IGM Resins yashoje Next Level Formulations I akoresheje "Ingaruka zo guhuza ibikoresho bikoresha Aminofunctional na Type I Photoinitiators."
Baroni yagize ati: “Ukurikije amakuru yagaragajwe kugeza ubu, bisa nkaho zimwe muri amine zirimo acrylate ari nziza mu gukumira ogisijeni kandi zishobora gukorana neza mu gihe hari abatera fotokopi bo mu bwoko bwa 1. Amine zikunze kugira ingaruka mbi cyane zatumye firime ivurwa ihinduka umuhondo. Twatekereje ko umuhondo ushobora kugabanuka binyuze mu kuvugurura ingano y’amine zirimo acrylate.”
Uburyo bwo gusesengura urwego rukurikira II
Isomo rya kabiri rya “Small Particle Sizes Pack a Punch: Additive Options to Anour Outstanding of UV Coatings Using Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options,” ryatanzwe na Brent Laurenti wo muri BYK USA. Laurenti yavuze ku nyongeramusaruro za UV crosslinking, SiO2 nanomaterials, inyongeramusaruro n'ikoranabuhanga rya PTFE-free wax.
Laurenti yagize ati: “Ibishishwa bidafite PTFE biduha ubushobozi bwo kugabanya ingano y’ibishishwa mu buryo bwiza muri bimwe mu bikorwa, kandi bishobora kubora 100%. Bishobora gukoreshwa mu buryo ubwo aribwo bwose bwo gusiga.”
Uwakurikiyeho ni Tony Wang wo muri Allnex, wavuze ku “Ibikoresho bya LED byo kunoza uburyo bwo kuvura ubuso hakoreshejwe LED kuri Litho cyangwa Flexo.”
“Kubuza umwuka wa ogisijeni kuzimya cyangwa gukuraho polymerization ikomeye,” Wang yagize ati: “Irushaho kuba mbi mu mabara yoroheje cyangwa make, nko mu mabara yo gupfunyika no mu mabara y’urumuri. Ibi bishobora gutuma habaho ubuso butoshye. Kuvura ubuso biragoye cyane mu kuvura LED kubera imbaraga nke no gufungana kw’uburebure bw’urumuri.”
Hanyuma, Kai Yang wo muri Evonik yavuze ku “Guteza imbere ingufu zivurwa zifata ku gice kigoye – Biturutse ku ngingo y’inyongera.”
“PDMS (polydimethylsilozanes) ni ubwoko bworoshye bwa siloxanes, kandi itanga ubushyuhe buke cyane ku buso kandi irahamye cyane,” Yang yavuze. “Itanga imiterere myiza yo kuzunguruka. Twanogeje imikoranire binyuze mu guhindura imiterere y’ibinyabuzima, bigenzura imiterere yayo yo kutagira amazi n’ubushyuhe bwayo. Imiterere yifuzwa ishobora guhindurwa hakoreshejwe impinduka z’imiterere. Twasanze polarity iri hejuru yongera ubushobozi bwo gushonga muri matrix ya UV. TEGO Glide ifasha kugenzura imiterere ya siloxanes za organomedified, mu gihe Tego RAD irushaho kunoza kunyerera no kurekura.”
Jason Ghaderi wo muri IGM Resins yasoje Next Level Formulations II mu kiganiro cye ku “Urethane Acrylate Oligomers: Ubushobozi bwo kwanduza filime zavuwe ku rumuri rwa UV n’ubushuhe burimo cyangwa budafite UV Absorbers.”
“Fomula zose zishingiye kuri UA oligomers nta muhondo zagaragaje ku maso kandi nta muhondo cyangwa ibara ryahindutse nk'uko byapimwe na spectrophotometer,” Ghaderi yagize ati: “Oligomers zoroshye za urethane acrylate zagaragaje imbaraga nke zo gukurura no gukoresha modulus mu gihe zigaragaza uburebure bwinshi. Imikorere ya oligomers ingana n'iy'imbaraga yari hagati, mu gihe oligomers zikomeye zatumye imbaraga nyinshi zo gukurura no gukoresha modulus zifite uburebure buke. Byagaragaye ko UV absorbers na HALS bibangamira uburyo bwo kuvura, bityo bigatuma guhuza filime yakize biri hasi ugereranyije n'uburyo budafite ibi byombi.”
Uburyo bwo gusesengura urwego rukurikira III
Next Level Formulations III yagaragaje Joe Lichtenhan wo muri Hybrid Plastics Inc., wavuze ku "POSS Additives for Dispersion and Viscosity Control," isura nk'inyongera za POSS, n'uburyo zishobora gufatwa nk'inyongera zigezweho zo mu bwoko bwa "coatings".
Lichtenhan yakurikiwe na Yang wa Evonik, ikiganiro cye cya kabiri cyari “Ikoreshwa ry’inyongera za Silika mu imashini zicapa UV.”
Yang yagize ati: “Mu buryo bwo gusiga UV/EB, silica yavuwe ku buso ni yo ikundwa cyane kuko guhagarara neza bishobora koroha kugerwaho mu gihe hagumana ubukana bwiza bwo gucapa.”
“Amahitamo yo gusiga UV ivurwa mu bijyanye no gukoresha imodoka imbere mu modoka,” byanditswe na Kristy Wagner, Red Spot Paint, ni yo yakurikiyeho.
Wagner yagize ati: “Irangi ry’urumuri rw’imirasire y’izuba rivurwa kandi ridafite ibara ryerekanye ko ritujuje gusa amabwiriza akomeye ya OEM ku bijyanye n’imikorere y’imodoka imbere mu modoka.”
Mike Idacavage, Radical Curing LLC, yashoje akoresheje "Low Viscosity Urethane Oligomers zikora nk'ibinyabutabire bitanga umusaruro," yavuze ko zishobora gukoreshwa mu inkjet, spray coating na 3D printing.
