Di-diluent tse arabelang (di-monomer)—tseo hangata di sebetsang mmoho le di-oligomer tse fodiswang ke UV—ke diketane tse kgutshwane, tse sebetsang ka bongata tse fetohang ka potlako marangrang a thata, a tshwarellang tlasa lesedi la ultraviolet (UV) kapa kganya ya dielektrone (EB). Hobane ke metsi a nang le viscosity e laolwang le dibaka tse ngata tse arabelang, di o dumella ho lokisa lebelo la pholiso, ho thatafala, ho tenyetseha, ho kgomarela le ho hanyetsa dikhemikhale ha o ntse o boloka VOC e le tlase.

Diluents tse arabelang ke eng?

Di-diluent tse arabelang di dula pakeng tsa dimolekhule tse nyane le di-polymer tse telele. Ditsamaisong tsa UV/EB di sebetsa e le di-reducer tsa viscosity (di fokotsa viscosity ha di ntse di arabela filiming) le di-crosslinkers (di phahamisa bongata ba marang-rang bakeng sa tshebetso). Malapa a tloaelehileng a mantlha a kenyelletsa di- le di-acrylate tse kang HDDA le TMPTA.

Mokhoa oa ho phekola UV/EB

Li-photoinitiator (UV) kapa matla a EB a tobileng li hlahisa li-radical tse bulang litlamo tse habeli tsa acrylate ho li-monomers le li-oligomers tsa hau. Liketane lia hola 'me lia hokahana ka har'a li-millisecond ho isa metsotsoana, li hlahisa filimi e tiileng e nang le thepa e reriloeng. Ha ho hlokahale ho baka, ho kenya matla a tlase, ho fetisa matla a mangata.

Litheko tse kholo tsa thepa

Ho tsikinyeha ha ho bapisoa le lintho tse tiileng: Li-monomer tse nang le ho tsikinyeha ho tlase (mohlala, HDDA) li eketsa lintho tse tiileng le ho phalla ntle le ho eketsa solvent.

● Lebelo la ho folisa khahlanong le taolo: Li-acrylate hangata li folisa ka potlako haholo, li fa li-formulator taolo e tiileng holim'a lebelo la mola.

● Botenya ba Crosslink khahlanong le ho tiea: TMPTA e sebetsang ka mekhahlelo e meraro e khanna ho tiea/ho hanyetsa lik'hemik'hale empa e ka phahamisa ho robeha le ho fokotseha ha matla; mesebetsi e sebetsang ka mekhahlelo e 'meli (HDDA) e thusa ho leka-lekanya le ho fana ka ho tenyetseha.

● Ho khomarela le ho ba mosehla: HDDA ke mokhoa o motle oa ho khomarela litšepe/polastiki le ho ba mosehla o fokolang; ho kopanya ka maano ho thusa ho etsa liphetho tse loketseng.

Ho khetha oligomer e nepahetseng

● HDDA (1,6-hexanediol diacrylate): e fola kapele haholo, e na le viscosity e tlase, e khomarela polasetiki/litšepe ka matla, e ba mosehla hanyane; e leka-lekanya lebelo le ho sebetsa habonolo.

● TMPTA (trimethylolpropane triacrylate): crosslinker e sebetsang ka mekhahlelo e meraro bakeng sa ho thatafala ho hoholo, ho hanyetsa solvent, le lebelo la mola—e sebelisoa ka bohlale ho laola ho robeha ha bonolo.

Lisebelisoa tsa mantlha(le mokhoa oa ho li sebelisa)

Likoahelo le enke tsa khatiso Sebelisa metsoako ea monomer ho fihlela lipheo tsa viscosity, throughput, le ho tšoarella ha tšebeliso ea qetellong.

● Sephetho se reriloeng: ka potlako pheko, ho beoa ha bonolo, ho thatafala ho hoholo/ho hanyetsa lik'hemik'hale, VOC e tlase.

● Likhetho tse tloaelehileng: HDDA bakeng sa lebelo/ho khomarela le bosehla bo tlase; TMPTA ho sutumelletsa ho thatafala/ho hanyetsa solvent.

● Ho qoela ka botebo: Sekoahelo sa Li-Coatings & Printa Inks

Likhomaretsi le li-sealant

Letsetsa nako ea ho lokisa, matla, le ts'ebetso ea mocheso/lik'hemik'hale.

● Sephetho se reriloeng: sete e potlakileng, litlamo tse matla holim'a litšepe/PC/ABS, tšebeletso e tšoarellang.

● Likhetho tse tloaelehileng: HDDA bakeng sa ho phunya le sesebelisoa se potlakileng se nang le ho khomarela ho matla ha substrate; TMPTA ha o hloka matla a botala a potlakileng le ho tiea ho hoholo ha ho qetela.

● Ho qoela ka botebo: Sehokelo sa Likhomaretsi le Li-Sealant

Li-resin tsa khatiso ea 3D le photolithography (SLA/DLP)

● Sephetho se reriloeng: litšobotsi tse ntle, ho fokotseha ho ka lebelloang, ho thatafala ho lokisitsoeng/HDT.

● Likhetho tse tloaelehileng: HDDA ho fokotsa ho teteana le ho ntlafatsa botšepehi ba khatiso; TMPTA ho eketsa botsitso ba litekanyo (motsoako ho laola ho tetebela ha letlalo).

● Ho teba ka botebo: Setsi sa Khatiso ea 3D le Photolithography

Polokeho le ho latela melao
