Otu n'ime ihe pụta ìhè nke ọgbakọ RadTech bụ nnọkọ na teknụzụ ọhụrụ. NaRadTech 2022, E nwere nnọkọ atọ a raara nye na nhazi ọkwa ọzọ, na ngwa sitere na nkwakọ ngwaahịa nri, mkpuchi osisi, mkpuchi ụgbọ ala na ihe ndị ọzọ.
Nhazi ọkwa ọkwa I
Bruce Fillipo nke Ashland wepụrụ usoro nhazi ọkwa ọzọ nke m na "Mmetụta Monomer na mkpuchi eriri anya," lelee ka polyfunctionals nwere ike isi metụta eriri anya.
Filippo kwuru, "Anyị nwere ike nweta ihe eji arụ ọrụ monomer na-arụkọ ọrụ ọnụ yana polyfunctional - mbelata viscosity na mma solubility," Filippo kwuru. “Mkpụrụedemede emelitere homogeneity na-eme ka njikọ njikọta nke polyacrylates dị n'otu.
"Vinyl pyrrolidone tụrụ ndị kasị mma n'ozuzu Njirimara kenyere a isi ngwa anya eriri usoro, gụnyere magburu onwe viscosity suppression, elu elongation na tensile ike, na ukwuu karịa ma ọ bụ nhata ọgwụgwọ ọnụego vs. ndị ọzọ enyocha monofunctional acrylates," kwukwara Fillipo. Ngwongwo ndị ezubere iche na mkpuchi eriri anya yiri ngwa ndị ọzọ nwere ike ịgwọ UV dị ka ink na mkpuchi ọpụrụiche.
Marcus Hutchins nke Allnex sochiri "Enweta mkpuchi mkpuchi Ultra-Low Gloss Site na Oligomer Design and Technology." Hutchins kwurịtara ụzọ 100% mkpuchi UV na ndị na-emepụta matting, dịka ọmụmaatụ maka osisi.
"Nhọrọ maka mbelata gloss ọzọ gụnyere resins nwere obere ọrụ yana ndị na-emepe emepe matting," Hutchins kwukwara. "Iwetu ihe na-egbuke egbuke nwere ike iduga n'ọgba aghara. Ị nwere ike ịmepụta mmetụta wrinkle site na ọgwụgwọ excimer. Nhazi ngwá ọrụ bụ isi ihe na-eme ka ihu dị mma na-enweghị ntụpọ.
"Mmecha matte dị ala na mkpuchi dị elu na-aghọ ihe dị adị," Hutchins kwukwara. "Ihe ndị a na-agwọta UV nwere ike matte nke ọma site na imewe na teknụzụ molecule, na-ebelata ọnụ ọgụgụ nke ihe ndị na-emepụta matting dị mkpa ma na-eme ka ọkụ na nkwụsị nkwụsị."
Richard Plenderleith nke Sartomer kwuziri okwu banyere "Ụzọ Maka Mbelata Mbugharị Mbugharị na Arts eserese." Plenderleith rụtụrụ aka na ihe dịka 70% nke nkwakọ ngwaahịa bụ maka nkwakọ nri.
Plenderleith gbakwụnyere na ink UV ọkọlọtọ adabaghị maka nkwakọ nri ozugbo, ebe achọrọ ink UV dị ala maka nkwakọ nri na-apụtaghị ìhè.
Plenderleith kwuru, "Nhọrọ nke akụrụngwa kachasị mma bụ isi ihe iji belata ihe egwu mbata. "Ihe nwere ike ime site na mmetọ mpịakọta n'oge a na-ebipụta akwụkwọ, UV oriọna na-adịghị agwọta oge niile, ma ọ bụ na-apụ apụ na nchekwa. Sistemu UV bụ akụkụ nke ụlọ ọrụ nkwakọ ngwaahịa nri dịka ọ bụ nkà na ụzụ na-enweghị ihe mgbaze."
Plenderleith rụtụrụ aka na ihe ndị chọrọ nkwakọ ngwaahịa nri na-esiwanye ike.
Ọ gbakwụnyere, "Anyị na-ahụ mmegharị siri ike na UV LED, yana mmepe nke ngwọta dị mma na-emezu ihe achọrọ ọgwụgwọ LED bụ isi." "Mmelite mmeghachi omume ka anyị na-ebelata mbugharị na ihe egwu chọrọ ka anyị rụọ ọrụ na fotointiators na acrylates."
Camila Baroni nke IGM Resins mechiri Nhazi Ọkwa na-esote I na "Mmetụta Mmekọrịta nke ijikọta ihe Aminofunctional na Ụdị I Photoinitiators."
"Site na data egosiri ugbu a, ọ dị ka ụfọdụ n'ime acrylated amines bụ ezigbo ikuku oxygen ma nwee ike dị ka synergists na ọnụnọ nke ụdị 1 photoinitiators," Baroni kwuru. "Amine kachasị na-emeghachi omume mere ka ihe nkiri ahụ gwọọ ọrịa na-acha odo odo na-achọghị. Anyị echewo na enwere ike ibelata odo site na ngbanwe nke ọdịnaya acrylated acrylated."

Na-esote ọkwa Formulations II malitere na "Obere urughuru Sizes Pack a Punch: Mgbakwunye Nhọrọ iji melite elu arụmọrụ nke UV mkpuchi iji Cross-Linkable, Nanoparticle Dispersions ma ọ bụ Micronized Wax Nhọrọ," nke Brent Laurenti nke BYK USA gosipụtara. Laurenti tụlere ihe mgbakwunye UV crosslinking, SiO2 nanomaterials, mgbakwunye na teknụzụ wax na-enweghị PTFE.
"Waks na-enweghị PTFE na-enye anyị arụmọrụ ọkwa dị mma na ngwa ụfọdụ, na ha bụ 100% biodegradable," Laurenti kọrọ. "Ọ nwere ike ịbanye n'ihe fọrọ nke nta ka ọ bụrụ usoro mkpuchi ọ bụla."
Onye na-esote bụ Tony Wang nke Allnex, onye kwuru maka "LED Boosters to Melite Surface Cure by LED for Litho or Flexo Application."
"Mgbochi oxygen na-emenyụ ma ọ bụ na-ewepụ polymerization radical," Wang kwuru. "Ọ na-akawanye njọ na mkpuchi dị nro ma ọ bụ obere viscosity, dị ka mkpuchi mkpuchi na inks. Nke a nwere ike ịmepụta elu dị egwu. Ngwọta elu na-esiwanye ike maka ọgwụgwọ LED n'ihi obere ike na mkpọchi nke mkpụmkpụ wavelength."
Evonik's Kai Yang tụlekwara "Ịkwalite ike na-edozi ike ka ọ bụrụ mkpụrụ siri ike - Site na akụkụ mgbakwunye."
"PDMS (polydimethylsilozanes) bụ klas kachasị mfe nke siloxanes, ma na-enye esemokwu elu dị ala ma kwụsie ike," Yang kwuru. "Ọ na-enye ihe ndị dị mma na-egbuke egbuke. Anyị kwalitere ndakọrịta site na mgbanwe organic, nke na-achịkwa hydrophobicity na hydrophilicity. A na-ahazi ihe ndị a na-achọsi ike site na nhazi nhazi.
Jason Ghaderi nke IGM Resins mechiri ọkwa na-esote ọkwa II n'okwu ya na "Urethane Acrylate Oligomers: Mmetụta nke ihe nkiri gwọọ ya na ọkụ UV na mmiri na enweghị UV Absorbers."
"Ụdị usoro niile dabere na UA oligomers egosighi ọdo edo na anya gba ọtọ na ọ fọrọ nke nta ka ọ bụrụ enweghị odo ma ọ bụ ngbanwe dị ka spectrophotometer tụrụ atụ," Ghaderi kwuru. "Urethane acrylate oligomers Soft urethane gosipụtara ike ike na modulus dị ala mgbe ha na-egosipụta na elu elongation. Semi-hard oligomers arụmọrụ dị n'etiti, ebe ndị oligomers siri ike rụpụtara ike dị elu na modul na elongation dị ala.
Usoro Ọkwa na-esote III
Ụdị ọkwa nke ọzọ nke atọ gosipụtara Joe Lichtenhan nke Hybrid Plastics Inc., bụ onye kpuchiri "Ihe mgbakwunye POSS maka mgbasa na njikwa viscosity," anya dị ka ihe mgbakwunye POSS, yana otu esi ewere ha dị ka ihe mgbakwunye ngwakọ smart maka usoro mkpuchi.
Evonik's Yang sochiri Lichtenhan, onye ihe ngosi ya nke abụọ bụ “Ojiji nke Silica Additives na UV Printing Ink.”
"N'ime usoro ọgwụgwọ UV / EB, silica a na-emeso elu bụ ngwaahịa kachasị amasị ebe ọ bụ na nkwụsi ike pụtara ìhè nwere ike ịdị mfe iji nweta ma na-ejigide viscosity dị mma maka ngwa obibi akwụkwọ," Yang kwuru.
"Nhọrọ mkpuchi mkpuchi UV maka ngwa ime ụlọ," nke Kristy Wagner, Red Spot Paint, na-esote.
Wagner kwuru, "UV nwere ike gwọọ doro anya na mkpuchi pigmented egosila na ọ bụghị naanị na ha na-ezute mana gafere nkọwa siri ike nke OEM ugbu a maka ngwa ụgbọ ala ime ụlọ," Wagner kwuru.
Mike Idacavage, Radical Curing LLC, mechiri "Low viscosity Urethane Oligomers nke na-arụ ọrụ dị ka Reactive Diluents," nke o kwuru na enwere ike iji inkjet, mkpuchi ịgba na ngwa mbipụta 3D.
