Ii-diluents ezisebenzayo (ii-monomers)—ezihlala zisebenza kunye nee-oligomers ezinyangekayo ze-UV—ziitsheyini ezimfutshane, ezisebenzayo ezininzi eziguquka ngokukhawuleza zibe ziinethiwekhi eziqinileyo nezihlala ixesha elide phantsi kokukhanya kwe-ultraviolet (UV) okanye i-electron beam (EB). Ngenxa yokuba zilulwelo olune-viscosity elawulwayo kunye neendawo ezininzi ezisebenzayo, zikuvumela ukuba ulungise isantya sokuphilisa, ubulukhuni, ukuguquguquka, ukunamathela, kunye nokumelana neekhemikhali ngelixa ugcina i-VOC iphantsi.

Zithini ii-reactive diluents?

Ii-diluents ezisebenzayo zihlala phakathi kwee-molecules ezincinci kunye nee-polymers ezinde. Kwiinkqubo ze-UV/EB zisebenza njengezinciphisi ze-viscosity (zehlisa i-viscosity ngelixa zisasabela kwifilimu) kunye nee-crosslinkers (ziphakamisa uxinano lwenethiwekhi ukuze isebenze). Iintsapho eziqhelekileyo ze-core ziquka ii-di- kunye nee-tri-acrylates ezifana ne-HDDA kunye ne-TMPTA.

Indlela esebenza ngayo i-UV/EB yokunyanga

Ii-Photoinitiators (UV) okanye amandla e-EB ngqo avelisa ii-radicals ezivula ii-acrylate double bonds kwii-monomers zakho kunye nee-oligomers. Iitsheyini ziyakhula kwaye ziqhagamshelane ngaphakathi kwee-milliseconds ukuya kwimizuzwana, zivelisa ifilimu eqinileyo eneempawu ezijoliswe kuyo. Akukho mfuneko yokubhaka, igalelo lamandla aphantsi, i-throughput ephezulu.

Ukutshintshiselana okukhulu kwepropathi

Ukuxinana xa kuthelekiswa nezinto eziqinileyo: Iimonomers ezixineneyo (umz., i-HDDA) zonyusa izinto eziqinileyo kwaye zihambe ngaphandle kokongeza isinyibilikisi.

● Isantya sokunyanga ngokuchasene nolawulo: Ii-acrylates zihlala zinyanga ngokukhawuleza kakhulu, zinika ii-formulators ulawulo oluqinileyo kwisantya somgca.

● Uxinano lwe-Crosslink vs. ukuqina: I-TMPTA esebenza ngeendlela ezintathu iqhuba ubulukhuni/ukumelana neekhemikhali kodwa inokunyusa ubulukhuni kunye nokuncipha; ii-di-functionals (HDDA) zinceda ukulinganisela kunye nokubonelela ngokuguquguquka.

● Ukuncamathela kunye nokutyheli: I-HDDA yindlela efanelekileyo yokuncamathela kwisinyithi/iplastiki kunye nokutyheli okuncinci; ukudibanisa ngobuchule kunceda ekulungiseleleni iziphumo.

Ukukhetha i-oligomer efanelekileyo

● I-HDDA (1,6-hexanediol diacrylate): iyakhawuleza ukuphiliswa, i-viscosity ephantsi, inamathela kakhulu kwiiplastiki/iintsimbi, i-tyheli ephantsi; ilungelelanisa isantya kunye nokuqhubekeka kokusebenza.

● I-TMPTA (i-trimethylolpropane triacrylate): i-crosslinker esebenza ngeendlela ezintathu yokuqina okuphezulu, ukumelana nesinyibilikisi, kunye nesantya somgca—isetyenziswe ngobuchule ukulawula ukubuthathaka.

Izicelo eziphambili(kunye nendlela yokuzisebenzisa)

Iingubo kunye nee-inki zokuprinta Sebenzisa imixube ye-monomer ukuze ufikelele kwiithagethi ze-viscosity, i-output, kunye nokuqina kokusetyenziswa.

● Isiphumo esijoliswe kuso: ngokukhawuleza ukuphilisa, ukubekwa kakuhle, ubunzima obuphezulu/ukuxhathisa iikhemikhali, i-VOC ephantsi.

● Iinketho eziqhelekileyo: I-HDDA yesantya/ukunamathela kunye nokutyheli okuphantsi; I-TMPTA yokutyhala ubulukhuni/ukuxhathisa isinyibilikisi.

● Ukuntywila nzulu: Iingubo kunye ne-Printing Inks hub

Izinto zokuncamathelisa kunye nezitywini

Cofa ixesha lokufakelwa, amandla, kunye nokusebenza kobushushu/iikhemikhali.

● Isiphumo esijoliswe kuso: iseti ekhawulezileyo, iibhondi eziqinileyo kwiintsimbi/PC/ABS, inkonzo ehlala ixesha elide.

● Iipiki eziqhelekileyo: I-HDDA yokutshixa kunye nesixhobo esikhawulezayo esinamatheliso aqinileyo e-substrate; i-TMPTA xa ufuna amandla aluhlaza okomzuzwana kunye nobunzima obuphezulu bokugqibela.

● Ukuntywila nzulu: Izincamathelisi kunye neSealants hub

Iiresini ze-3D-printing kunye ne-photolithography (SLA/DLP)

Isisombululo sebhalansi, amandla aluhlaza, kunye neendlela zokugqibela.

● Isiphumo esijoliswe kuso: iimpawu ezintle, ukuncitshiswa okuqikelelweyo, ukuqina okulungisiweyo/i-HDT.

● Iinketho eziqhelekileyo: I-HDDA yokunciphisa i-viscosity kunye nokuphucula ukuthembeka kokuprinta; I-TMPTA yokwandisa uzinzo olunemilinganiselo (umxube wokulawula ukuqhekeka).

● Ukuntywila nzulu: Isikhungo sokuPrinta se-3D kunye nePhotolithography

Ukhuseleko kunye nokuthobela imithetho

Zombini zizinto ezithintela ulusu/ukuphefumla; sebenzisa iiglavu, iiglasi zokukhusela umoya, kunye nokungenisa umoya. Qinisekisa ukuba iilebheli kunye nokuhambelana kobhaliso kwimarike yakho kwaye ugcine i-QC eqinileyo (ukuqaqamba, ixabiso le-asidi, i-residual monomer, umbala, i-gel fraction).
