Ukupakishwa kwe-SIUMAI kuprintwe ngeUV inkikuwo wonke umzi-mveliso wethu.Sihlala sifumana imibuzo kubathengi Yintoni i-inki yesintu?Yintoni i-inki ye-UV?Yintoni umahluko phakathi kwabo?Ngokwembono yomthengi, sizimisele ngakumbi ukukhetha inkqubo yoshicilelo enengqiqo enesiphumo esingcono kunye neendleko eziphantsi.

*Umahluko phakathi kwe-inki yemveli kunye ne-UV inki

Ngamafutshane, umahluko omkhulu phakathi kwee-inki ezimbini ukwindlela yokomisa kunye nendlela yokushicilela.Ushicilelo lwe-inki lwemveli luya kutshiza umaleko womgubo ephepheni emva kokushicilela, ukuze xa iphepha kunye nephepha zidityanisiwe, kukho umaleko we-diaphragm phakathi ukukhusela i-inki ukuba ibambelele kwaye Yenza i-inki yome ngokukhawuleza.Iinki zemveli zithatha ixesha elithile ukuze zome emva kokushicilela.Ukuba lo maleko womgubo awutshizwanga, i-inki ekwiphepha iya kuthandeka ukunamathelana kwaye yonakalise lonke ushicilelo.

* Umahluko kuluhlu loshicilelo

Ukuba iprintwe kwaye itshizwe ngeenkqubo eziqhelekileyo, kuya kuthatha malunga nosuku ukuba yome ngokupheleleyo.Ngokuqinisekileyo, amanye amaphepha aya kuba nexesha elifutshane lokumisa.Iinki zemveli zinokuprintwa kuphela ephepheni, kodwa azinakuprintwa kwiplastiki okanye kwezinye izinto.Ngokuchaseneyo, ii-inks ze-UV zinezixhobo ezininzi zokuprinta, ngoko ke ixabiso le-inks ze-UV liphezulu.

*Umgaqo kunye nokusetyenziswa kokomisa inki ye-UV

I-inki yokushicilela ye-UV yongezwa kunye ne-reactant edibana nokukhanya kwe-ultraviolet.Ngethuba lenkqubo yokushicilela, inyathelo lokukhanyisa ukukhanya kwe-ultraviolet kuya kongezwa, ukwenzela ukuba inkino yomiswe ngokukhawuleza, kwaye inyathelo elilandelayo lokucubungula okanye ukuthunyelwa lingenziwa ngokukhawuleza emva kokuprintwa.Umphezulu oshicilelweyo uya kuba mde kakhulu.Iinki ze-UV zineempawu zokuncamathela ezigqwesileyo phantse kuwo nawuphi na umphezulu wezinto eziphathekayo, njengepolyethylene, ivinyl, isitayile, ipholycarbonate, iglasi, intsimbi, njl. Ukongeza, ukuba ufuna ukuprinta kwiphepha elinombala okanye izinto, okoko nje ukongeza umaleko i-inki emhlophe kumphezulu, akukho mfuneko yakukhathazeka ukuba umbala wokushicilela uya kungqubana nombala wezinto eziphathekayo.

Xa i-inki ye-UV ishicilelwe, i-inki ibambelela kumphezulu we-substrate, kwaye amandla e-photoinitiator avuyiswa yi-irradiation ye-ultraviolet, kunye ne-polymerization reaction yenzeke kunye ne-oligomer kunye ne-monomer ngephanyazo ukunyanga i-conjunctiva.I-inki enyangekayo ye-UV ayinayo i-volatile organic compounds (VOC3), ngoko ayibangeli ungcoliseko emoyeni kunye nomonakalo kumzimba womntu.Iyoma kuphela xa ibonakaliswe kukukhanya kwe-UV, kwaye i-perfor mance ihlala izinzile nasemva kokugcinwa kwexesha elide kumthombo we-inki.

I-inki ye-UV inesantya sokumisa ngokukhawuleza kwaye inokomiswa ngokukhawuleza emva kokushicilela.Akunakunciphisa kuphela umjikelezo wemveliso, ukuphucula ukusebenza kakuhle kwemveliso, ukugcina amandla kunye nokusebenza kakuhle, kodwa kwakhona ukukhansela isixhobo sokutshiza umgubo womatshini wokushicilela we-offset, ophucula kakhulu indawo yokusebenza.Ngenxa yokuba i-inki ye-UV yoma ngokukhawuleza, ayiyi kungena kwi-substrate, kwaye ayiyi kuchaphazela umgangatho wendalo we-substrate, ilungele ngakumbi ukuprintwa kombala weemveliso zokupakisha.
