Zvikamu zvitatu zvekutanga zvinoratidza matekinoroji matsva ari kupihwa mumunda wekugadzirisa simba.
Chimwe chezvinhu zvinonyanya kukosha pamisangano yeRadTech imisangano pamusoro pematekinoroji matsva.RadTech 2022, paive nezvikamu zvitatu zvakatsaurirwa kuNext Level Formulations, nekushandiswa kwacho kunosanganisira kurongedza chikafu, kuputira huni, kuputira mota nezvimwe.
Mafomula Edanho Rinotevera I
Bruce Fillipo weAshland akatungamira chikamu cheNext Level Formulations I ne "Monomer Impact on Optical Fiber Coatings," kutarisa kuti polyfunctionals inogona sei kukanganisa fibers dze optical.
"Tinogona kuwana hunhu hwemonomer inoshanda pamwe chete ine mapolyfunctional - kudzvinyirira viscosity uye kunatsiridza kunyunguduka," Filippo akadaro. "Kugadzirwa kwakagadziridzwa kunoita kuti polyacrylates ibatane zvakanaka.
"Vinyl pyrrolidone yakayera hunhu hwakanakisa hwese hunopihwa kune iyo yekutanga fiber ye optical, kusanganisira kudzvinyirira kwakanaka kwe viscosity, kureba kwepamusoro uye simba rekusunga, uye chiyero chikuru chekuporesa kupfuura kana chakaenzana kana tichienzanisa nemamwe ma acrylates e monofunctional akaongororwa," akawedzera Fillipo. "Hunhu hwakanangana ne optical fiber coatings hwakafanana nedzimwe UV applications dzinogona kurapwa dzakadai se inks uye specialty coatings."
Marcus Hutchins weAllnex akateverwa ne "Kuwana Mapendi Akajeka Akanyanya Kupenya Kuburikidza neOligomer Design and Technology." Hutchins vakakurukura nzira dzekushandisa mapendi eUV 100% ne matting agents, semuenzaniso ehuni.
"Sarudzo dzekuwedzera kuderedza kupenya dzinosanganisira maresini ane mashandiro mashoma uye kugadzira matting agents," Hutchins akawedzera. "Kuderedza kupenya kunogona kukonzera mavanga ekuora. Unogona kugadzira makwinya kuburikidza ne excimer curing. Kugadzira michina kwakakosha kuti uve nechokwadi chekuti pamusoro payo pakachena pasina zvikanganiso.
"Kupedzwa kwemavara asina kusimba uye machira anoshanda zvakanyanya kuri kuitika," Hutchins akawedzera. "Zvinhu zvinorapika zveUV zvinogona kupenya kuburikidza nekugadzirwa kwemamorekuru netekinoroji, zvichideredza huwandu hwezvinhu zvinodiwa pamadziro uye zvichivandudza kupenya uye kuramba mavara."
Richard Plenderleith weSartomer akabva ataura nezve "Maitiro Ekuderedza Kutama Kwevanhu muGraphic Arts." Plenderleith akataura kuti inenge 70% yekurongedza ndeyekurongedza chikafu.
Plenderleith akawedzera kuti inki dzeUV dzakajairwa hadzina kukodzera kurongedza chikafu zvakananga, nepo inki dzeUV dzisingafambi zvakanyanya dzichidiwa pakurongedza chikafu zvisina kunanga.
"Kusarudzwa kwezvinhu zvakagadzirwa zvakanaka kwakakosha kuderedza njodzi dzekutama," akadaro Plenderleith. "Matambudziko anogona kuitika kubva pakusvibiswa kwemupumburu panguva yekudhinda, marambi eUV asingapenye mukati mese, kana kudzima kutamiswa kwemupumburu mushure mekuchengetwa. Masisitimu eUV chikamu chekukura kweindasitiri yekurongedza chikafu sezvo iri tekinoroji isina zvinonyungudutsa."
Plenderleith akataura kuti zvinodiwa pakurongedza chikafu zviri kuramba zvichiwedzera kuoma.
"Tinoona kufamba kwakasimba kuchiedza cheUV LED, uye kugadzirwa kwemhinduro dzinoshanda dzinozadzisa zvinodiwa neLED kuporesa kwakakosha," akawedzera. "Kuvandudza reactivity uku tichideredza kufamba uye njodzi zvinoda kuti tishande pa photointiators ne acrylates."
Camila Baroni weIGM Resins akavhara Next Level Formulations I ne "The Synergistic Effect of Combination Aminofunctional Materials with Type I Photoinitiators."
"Kubva padata rakaratidzwa kusvika pari zvino, zvinoita sekunge mamwe emamine ane acrylated anodzivirira okisijeni zvakanaka uye anogona kushanda pamwe chete kana paine ma photoinitiators erudzi rwekutanga," akadaro Baroni. "Mamine anonyanya kushanda akakonzera mhedzisiro ye yellowing isingadiwe yefirimu rakaporeswa. Taifunga kuti yellowing inogona kuderedzwa nekugadziriswa kwehuwandu hweamine ane acrylated."
Mafomuro Edanho Rinotevera II
Next Level Formulations II yakatanga ne "Small Particle Sizes Pack a Punch: Additive Options to Improve Surface Performance of UV Coatings Using Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options," yakaunzwa naBrent Laurenti weBYK USA. Laurenti akakurukura nezveUV crosslinking additives, SiO2 nanomaterials, additives uye PTFE-free wax technology.
"Wakisi isina PTFE iri kutipa mashandiro ari nani ekuenzanisa mune mamwe mashandisirwo, uye inogona kuora 100%," akadaro Laurenti. "Inogona kushandiswa mumhando ipi zvayo yekupenda."
Akatevera aive Tony Wang weAllnex, uyo akataura nezve "LED Boosters yekuvandudza Surface Cure ne LED yeLitho kana Flexo Applications."
"Kudziviswa kweokisijeni kunodzima kana kubvisa radical polymerization," akadaro Wang. "Inonyanya kuoma kana yakatetepa kana yakaderera viscosity coatings, senge packing coatings ne inks. Izvi zvinogona kugadzira pamusoro unonamira. Kurapa pamusoro kunonetsa zvikuru pakurapa LED nekuda kwekushomeka kwesimba uye kukiya kwe shorty wavelength."
Kai Yang waEvonik akazokurukura nezve "Kukurudzira Simba Rinorapika Kunamatira Kunzvimbo Yakaoma - Kubva Pakuwedzera."
"PDMS (polydimethylsilozanes) ndiyo mhando iri nyore ye siloxanes, uye inopa kushushikana kwakaderera uye yakagadzikana zvikuru," akadaro Yang. "Inopa hunhu hwakanaka hwekutsvedza. Takavandudza kuenderana kwayo nekuchinja kwe organic, iyo inodzora hydrophobicity yayo uye hydrophilicity. Hunhu hwaunoda hunogona kugadziriswa nekuchinja kwechimiro. Takaona kuti polarity yakakwira inovandudza kunyungudika mu UV matrix. TEGO Glide inobatsira kudzora hunhu hwe organomodified siloxanes, nepo Tego RAD ichivandudza kutsvedza nekubuda."
Jason Ghaderi weIGM Resins akapedzisa Next Level Formulations II nehurukuro yake pamusoro pe "Urethane Acrylate Oligomers: Kunzwa Kwemafirimu Akacheneswa kuUV Light uye Moisture ine uye isina UV Absorbers."
"Mafomula ese akavakirwa paUA oligomers haana kuratidza kutsvuka kweyero mumaziso uye haana kutsvuka kweyero kana kusviba kweruvara sezvakayerwa nespectrophotometer," akadaro Ghaderi. "Masoft urethane acrylate oligomers akaratidza kusimba kwakaderera kwekudhonza uye modulus uku achiratidza kurefu kwakakwirira. Kushanda kwemasemi-hard oligomers kwaive pakati, nepo mahard oligomers akaita kuti kusimba kwakakwira kwekudhonza uye modulus kuve kurefu kwakaderera. Zvinoonekwa kuti UV absorbers neHALS zvinokanganisa mushonga, uye nekuda kweizvozvo, kubatanidza kwefirimu rakacheneswa kwakaderera pane kwesystem isina izvi zviviri."
Mafomuro Edanho Rinotevera III
Next Level Formulations III yaisanganisira Joe Lichtenhan weHybrid Plastics Inc., uyo akataura nezve "POSS Additives for Dispersion and Viscosity Control," chitarisiko chePOSS additives, uye kuti dzinogona sei kunzi additives dzakangwara dzema coatings systems.
Lichtenhan akateverwa naEvonik's Yang, uyo hurukuro yake yechipiri yaive "Kushandiswa kweSilica Additives muUV Printing Inks."
"MumaUV/EB curazing formulations, silica yakacheneswa pamusoro ndiyo chinhu chinodiwa sezvo kugadzikana kwakanyanya kunogona kuve nyore kuwana uku uchichengetedza viscosity yakanaka yekushandisa pakudhinda," Yang akadaro.
"Sarudzo dzeUV Inorapika dzekushandisa mota dzemukati," rakanyorwa naKristy Wagner, Red Spot Paint, ndiro rakatevera.
"Machira eUV anorapika uye ane ruvara anoratidza kuti haangogumiri pamatanho ekushandisa mota asi anopfuura zvinodiwa neOEM pakushandisa mota dzemukati," akadaro Wagner.
Mike Idacavage, weRadical Curing LLC, akapedzisa ne "Low Viscosity Urethane Oligomers dzinoshanda seReactive Diluents," dzaakataura kuti dzinogona kushandiswa mu inkjet, spray coating uye 3D printing applications.
