iindaba

Kwintsimi yoshicilelo, i-inki esetyenziselwa ukushicilela nayo ibonise iimfuno ezihambelanayo, i-inki ye-UV yokunyanga ngokukhawuleza, ukhuseleko lokusingqongileyo kunye nezinye iingenelo zoshicilelo.I-inki yokuprinta ye-UV kulo lonke ushicilelo lwe-offset, i-letterpress, ushicilelo lwegravure, ushicilelo lwesikrini kunye noshicilelo lwe-inkjet kunye nezinye iindawo zokuprinta, eli nqaku labelana ngolwazi olunxulumene ne-Ink ye-UV, umxholo wereferensi yabahlobo:

Ingcaciso

I-UV: Ifutshane kwisibane se-ultraviolet.I-Ultraviolet (UV) ayibonakali ngeliso lenyama.Licandelo lemitha yemitha yombane ngaphandle kokukhanya okumfusa okubonakalayo.Ubude bobude bukuluhlu lwe-10 ~ 400nm

I-inki ye-UV: I-inki ye-UV, ibhekiselele kwi-inki yokukhanya kwe-UV ngoko nangoko

Iimpawu

1, isantya sokumisa siyakhawuleza, gcina ixesha, phantsi kokukhanya kwe-UV, kufuneka imizuzwana embalwa ukuya kwimizuzwana embalwa inokunyangwa.

2, izixhobo zibandakanya indawo encinci, ukusebenza kokuhamba kokushicilela, ukonga abasebenzi, iinzuzo zoqoqosho.

3, kunayo nayiphi na i-inki ngaphandle kokuba ngumphunga wendalo wokomisa i-inki, inokonga amandla.

4, kwimeko yobunzima befilimu eyomileyo efanayo, ukonga ngakumbi kwe-inki.

5, ayiyi kugquma, ukuba nje ungaqhagamshelani nemitha ye-ultraviolet ayiyi kumisa ngokuqinileyo kwi-inki.

I-6, uzinzo oluhle lombala.

7, ukukhanya okuphezulu.

I-8, amasuntswana e-inki amancinci, angaprinta iipateni ezilungileyo.

I-9, indawo yokushicilela umoya omtsha, ivumba elincinci, akukho VOC.

Izithako eziphambili

Amacandelo aphambili e-inki ye-UV abandakanya i-pigment, i-oligomer, i-monomer (i-diluent esebenzayo), i-photoinitiator kunye neentlobo ezahlukeneyo zokuncedisa.Phakathi kwabo, i-resin kunye ne-diluent esebenzayo idlala indima yokulungisa i-pigment kunye nokubonelela ngeempawu zokwenza ifilimu;Ii-pigments zinika i-inki umbala ophakathi kunye namandla okugubungela kwi-substrate;I-Photoinitiator iyadingeka ukuze ikwazi ukufunxa iifotoni phantsi kokuphazamiseka kwee-pigments ukuqalisa i-polymerization.

1, IiCompounds zeMonomolecular (diluent esebenzayo)

Le yikhompawundi elula enobunzima obuncinci bemolekyuli, inokunciphisa i-viscosity, idlale indima yokusasaza, inokusasaza ii-pigments, inyibilikise i-resin, imisele isantya sokunyanga kunye nokuncamathela kwe-inki, kwaye ithathe inxaxheba kwi-resin ye-UV ephilisa i-crosslinking reaction.

2, izongezo

Kubandakanya i-pigments, i-lubricants, i-ejenti yokuqina, i-agent, i-ejenti yokuqinisa, njl. Ichaphazela i-ink gloss, i-viscosity, ukuthamba, umbala, ubukhulu befilimu, isantya sokuphilisa, ukufaneleka kokushicilela kunye nezinye iimpawu.

I-3, i-Resin eLizileyo eKhanyayo yi-UV Ink yokuDibanisa iMaterial

Isantya sokunyanga i-UV, isilungiseleli seglosi, ukuncamathela, ukuxhathisa ukungqubana kunye nezinye iipropathi, i-inki eyahlukileyo ineentlobo ezahlukeneyo zeresin exutyiweyo.

4, Umqalisi wokukhanya

Umqalisi wokukhanya njengebhulorho phakathi kokusabela kweekhemikhali, luhlobo oluthile lokukhanya okukhanya lusebenza kakhulu, emva kokufunxa iifotoni zivelisa ii-radicals zasimahla, amandla okudluliselwa kweradical yasimahla kwezinye iipolymer ezithatha i-photosensitive, ukuvelisa i-chain reaction, i-molecule enye, i-additive, i-resin eqinile yokukhanya. kunye, yenza i-inki yokunyanga ukuphendula, kwaye emva kokukhululwa kwamandla ngokwayo ayibandakanyekanga kwi-crosslinking reaction.

Umgaqo wokuqinisa

Ngaphantsi kwemisebe yokukhanya kwe-ultraviolet, ukufunxwa kokukhanya kokukhanya ukuvelisa i-radicals yasimahla, umsebenzi we-radical wasimahla kwisantya esiphezulu, ungquzulwano lwenzeka kunye ne-resin kunye nekhompawundi yemolekyuli enye, ukuhanjiswa kwamandla kwi-resin kunye neekhompawundi zemolekyuli enye, i-resin kunye ne-molecular compound enye. emva kokufunxa i-excitation yamandla equlethe i-athom ye-unsaturated double bond i-polymerized monomer polymer kunye ne-radicals, oko kukuthi, i-resin kunye ne-molecule enye yeekhompawundi, Bavula ibhondi ephindwe kabini kwaye baqale ukusabela okuxhamlayo, unyango oludibanisa umnqamlezo, apho i-photoinitiator ilahlekelwa amandla kwaye ibuyele. kwimo yayo yokuqala.

Izinto Ezichaphazelayo

I-inki yokunyanga ye-UV kufuneka ibe nesibane se-UV ukunyanga, kungenjalo ayinakusetyenziswa.Ekusetyenzisweni kwe-inki ye-UV, ingxaki yokuqala yokubambelela kukuba i-inki ye-UV ayinayo ukunyanga okunzulu.Ngokubhekiselele kwisixhobo esiqinileyo sokukhanya, isizathu sisenokuba kukungaphumeleli kwezixhobo zokunyanga ze-UV, oko kukuthi, ububanzi be-wavelength yezixhobo zokunyanga ze-UV azihambelani nokukhanya kwe-inki eqinileyo ye-UV, okanye ukukhanya okuqinileyo akwanelanga, okanye isantya esiluqilima esikhanyayo akwanelanga. kufanelekile.

1, ukukhanya okuqinileyo kwe-inki ye-UV ukukhanya okuqinileyo kobuntununtunu bobume bobude phakathi kwe-180-420NM.

2, amandla esibane se-UV kufuneka ahlangabezane neemfuno zobuchwepheshe zokunyanga inki.

3, isantya soshicilelo ngokukhawuleza kakhulu sikwachaphazela isantya sokuphilisa se-inki.

I-4, impembelelo yobunzima be-inki, i-inki ingqindilili kakhulu iya kuchaphazela umphumo wokuphilisa, zonke izinto ezichaphazela ubukhulu befilimu yokushicilela ziya kuchaphazela umphumo wokuphilisa.

I-5, impembelelo yemozulu: ubushushu obuphezulu, i-viscosity ye-inki ye-UV iba phantsi, emva kokushicilela, kulula ukuvelisa i-paste version phenomenon.Ubushushu obuphantsi, i-viscosity ephezulu, ichaphazela i-thixotropy ye-inki, ubushushu be-workshop ayinakuba phezulu kakhulu, ebusika kwindawo yokugcina umoya kufuneka ibekwe kwindawo yokushisa, kwaye ifanele ithobe isantya sokunyanga.

I-6, impembelelo ye-pigment kwi-inki ye-UV: ngenxa yee-pigments ezahlukeneyo ekufakweni kokukhanya, ukubonakaliswa kunye nomxholo we-pigment ye-inki ngokubanzi, umhlophe, omnyama, oluhlaza okwesibhakabhaka kunzima ukunyanga, obomvu, omthubi, ioli ekhanyayo, ioli ecacileyo kulula ukuyinyanga. .
