Ama-diluent asebenzayo (ama-monomer)—avame ukusebenza kanye nama-oligomer alaphekayo e-UV—amaketanga amafushane, asebenza ngezindlela eziningi aguquka ngokushesha abe amanethiwekhi aqinile, aqinile ngaphansi kokukhanya kwe-ultraviolet (UV) noma i-electron beam (EB). Ngenxa yokuthi ayiziketshezi ezine-viscosity elawulwayo kanye nezindawo eziningi ezisabelayo, akuvumela ukuthi ulungise isivinini sokwelapha, ubulukhuni, ukuguquguquka, ukunamathela, kanye nokumelana namakhemikhali ngenkathi ugcina i-VOC iphansi.

Ziyini izidakamizwa zokunciphisa ukusabela?

Ama-diluent asebenzayo ahlala phakathi kwama-molecule amancane nama-polymer amade. Ezinhlelweni ze-UV/EB asebenza njengokunciphisa i-viscosity (ukwehlisa i-viscosity ngenkathi esasabela efilimini) kanye nama-crosslinkers (ukuphakamisa ubuningi benethiwekhi ukuze kusebenze). Imindeni ejwayelekile eyinhloko ifaka phakathi ama-di- nama-tri-acrylates njenge-HDDA kanye ne-TMPTA.

Indlela ukwelapha kwe-UV/EB okusebenza ngayo

Ama-Photoinitiators (UV) noma amandla e-EB aqondile akhiqiza ama-radical avula izibopho eziphindwe kabili ze-acrylate kuma-monomers akho nama-oligomers. Amaketanga ayakhula futhi axhumane ngaphakathi kwama-millisecond kuya kumasekhondi, akhiphe ifilimu eqinile enezakhiwo eziqondiwe. Akukho bhaka elidingekayo, ukufaka amandla aphansi, ukuphuma okuphezulu.

Ukuhwebelana okukhulu kwezindlu

Ukuqina vs. okuqinile: Ama-monomer ane-viscosity ephansi (isb., i-HDDA) andisa okuqinile futhi ageleze ngaphandle kokwengeza i-solvent.

● Isivinini sokwelapha vs. ukulawula: Ama-acrylates ngokuvamile aphulukisa ngokushesha okukhulu, enikeza abakhiqizi ukulawula okuqinile isivinini somugqa.

● Ubuningi be-Crosslink vs. ukuqina: I-TMPTA esebenza kathathu iqhuba ukuqina/ukumelana namakhemikhali kodwa ingakhuphula ukuphuka nokushwabana; imisebenzi ehlukahlukene (i-HDDA) isiza ukulinganisela nokunikeza ukuguquguquka.

● Ukunamathela kanye nokuba phuzi: I-HDDA iyindlela engcono kakhulu yokunamathela ezinsimbini/epulasitikini kanye nokuba phuzi okuphansi; ukuxuba ngamasu kusiza ukwenza imiphumela ibe ngcono.

Ukukhetha i-oligomer efanele

● I-HDDA (1,6-hexanediol diacrylate): iphola ngokushesha kakhulu, i-viscosity ephansi, inamathela ngokuqinile kumapulasitiki/izinsimbi, iphuzi eliphansi; ilinganisela isivinini kanye nokucutshungulwa.

● I-TMPTA (i-trimethylolpropane triacrylate): i-crosslinker esebenza nge-tri-functional yokuqina okuphezulu, ukumelana nesinyibilikisi, kanye nesivinini somugqa—sebenzisa ngokuhlakanipha ukuphatha ukuqhekeka.

Izinhlelo zokusebenza eziyinhloko(nokuthi ungawasebenzisa kanjani)

Ukumboza noyinki wokuphrinta Sebenzisa izingxube ze-monomer ukuze ufinyelele imigomo ye-viscosity, i-throughput, kanye nokuqina kokusetshenziswa kokugcina.

● Umphumela oqondiwe: okusheshayo ukwelapha, ukubekwa phansi okubushelelezi, ubulukhuni obuphezulu/ukumelana namakhemikhali, i-VOC ephansi.

● Ama-pick ajwayelekile: I-HDDA yesivinini/ukunamathela kanye nokuba phuzi okuphansi; I-TMPTA yokucindezela ukuqina/ukumelana nesinyibilikisi.

● Ukucwila okujulile: Ihabhu le-Coatings & Printing Inks

Izinamathiseli kanye nezinamathiseli

Shayela isikhathi sokufakwa, amandla, kanye nokusebenza kwezinga lokushisa/amakhemikhali.

● Umphumela oqondiwe: isethi esheshayo, izibopho eziqinile ezinsimbini/kwi-PC/ABS, isevisi eqinile.

● Ama-pick ajwayelekile: I-HDDA yokugoqa kanye ne-fixture esheshayo enokunamathela okuqinile kwe-substrate; i-TMPTA uma udinga amandla aluhlaza ngokushesha kanye nokuqina okuphezulu kokugcina.

● Ukucwila ngokujulile: Isikhungo Sokunamathisela Nama-Sealant

Ama-resin okunyathelisa nge-3D kanye ne-photolithography (i-SLA/DLP)

Isixazululo sebhalansi, amandla aluhlaza, kanye nobuchwepheshe bokugcina.

● Umphumela oqondiwe: izici ezinhle, ukuncishiswa okubikezelwayo, ukuqina okulungisiwe/i-HDT.

● Ukukhetha okujwayelekile: I-HDDA yokunciphisa ukujiya nokuthuthukisa ukuthembeka kokuphrinta; I-TMPTA yokwandisa ukuzinza kobukhulu (inhlanganisela yokulawula ukuqhekeka).

● Ukucwila okujulile: Isikhungo sokuphrinta se-3D kanye ne-Photolithography

Ukuphepha nokuthobela imithetho

Zombili ziyizinto zokwenza isikhumba/ukuphefumula zizizwe zikhululekile; sebenzisa amagilavu, izibuko zokubona, kanye nokufaka umoya. Qinisekisa ukuthi ilebula kanye nokuhambisana kokubhaliswa kwemakethe yakho futhi ugcine i-QC eqinile (ukuthamba, inani le-asidi, i-monomer eseleyo, umbala, ingxenye yejeli).
