Ushicilelo lweUV yindlela eyodwa yeushicilelo lwedijithaliusebenzisa ukukhanya kwe-ultraviolet (UV) ukomisa okanye ukunyanga i-inki, izinto zokuncamathelisa okanye izaleko phantse nje ukuba ibetheke ephepheni, okanye i-aluminium, ibhodi yogwebu okanye i-acrylic - enyanisweni, ukuba ingena kumshicileli, ubuchule bunokusetyenziswa printa phantse kuyo yonke into.
Ubuchwephesha bokunyanga kwe-UV - inkqubo ye-photochemical yokomisa - yaziswa ekuqaleni njengendlela yokomisa ngokukhawuleza i-gel izikhonkwane ze-nail polishes ezisetyenziswa kwi-manicure, kodwa isanda kwamkelwa lishishini lokushicilela apho lisetyenziselwa ukuprinta kuyo nayiphi na into evela kwiimpawu kunye neencwadana. kwiibhotile zebhiya.Inkqubo iyafana noshicilelo lwemveli, umahluko kuphela inki ezisetyenzisiweyo kunye nenkqubo yokomisa - kunye neemveliso eziphezulu eziveliswe.
Kushicilelo lwemveli, ii-inki zokunyibilikisa zisetyenziswa;ezi zinokujika zibe ngumphunga kwaye zikhuphe iikhompawundi eziguquguqukayo eziphilayo (VOCs) ezinobungozi kokusingqongileyo.Indlela iphinda ivelise - kwaye isebenzise - ubushushu kunye nevumba elikhaphayo.Ngaphaya koko, ifuna umgubo wokutshiza owongezelelweyo ukunceda ngenkqubo yokucima i-inki kunye nokomisa, okunokuthatha iintsuku ezininzi.Ii-inki zifakwe kwindawo yokushicilela, ukuze imibala ibonakale ihlanjiwe kwaye iphelile.Inkqubo yoshicilelo inqunyelwe ikakhulu kumaphepha kunye namakhadi, ngoko ayinakusetyenziswa kwizinto ezifana neplastiki, iglasi, isinyithi, i-foil okanye i-acrylic efana noshicilelo lwe-UV.
Kushicilelo lwe-UV, i-mercury/quartz okanye izibane ze-LED zisetyenziselwa ukunyanga endaweni yobushushu;ukukhanya kwe-UV eyilwe ngokukodwa okuphakamileyo kulandele ngokusondeleyo njengoko i-inki ekhethekileyo isasazwa kwindawo yokushicilela, iyomisa ngokukhawuleza ukuba ifakwe.Ngenxa yokuba i-inki iguquka ukusuka kwinto eqinileyo okanye incama iye kulwelo ngokukhawuleza, akukho thuba lokuba iguquke ibe ngumphunga kwaye ke akukho VOCs, imisi eyityhefu okanye i-ozone ikhutshwa, nto leyo eyenza ukuba itekhnoloji ihambelane nokusingqongileyo phantse ibe ngunothi wekhabhoni.
I-inki, i-adhesive okanye i-coating iqulethe umxube we-monomers zamanzi, ii-oligomers - iipolymers ezibandakanya iiyunithi ezimbalwa eziphindaphindiweyo - kunye ne-photoinitiators.Ngethuba lenkqubo yokuphilisa, ukukhanya okuphezulu kwi-ultraviolet inxalenye ye-spectrum, kunye ne-wavelength phakathi kwe-200 kunye ne-400 nm, ifunxwa yi-photoinitiator ehamba kwi-chemical reaction - i-chemical cross link - kwaye ibangela ukuba inki, i-coating okanye i-adhesive. qina ngoko nangoko.
Kulula ukubona ukuba kutheni ushicilelo lwe-UV lugqithise amanzi emveli kunye neendlela zokomisa ze-solvent-based kunye nokuba kutheni kulindeleke ukuba kuqhubeke ukukhula ekuthandeni.Akunjalo kuphela indlela yokukhawulezisa imveliso - oku kuthetha ukuba kuninzi kwenziwa ngexesha elincinci - amazinga okulahlwa ayancitshiswa njengoko umgangatho uphezulu.Amathontsi amanzi e-inki ayapheliswa, ngoko ke akukho kuxutywa okanye ukuhlambalaza, kwaye njengoko ukomisa kusondele ngokukhawuleza, akukho mpuphu kwaye ngenxa yoko akukho lahleko yobunzima bokugquma okanye umthamo.Iinkcukacha eziphucukileyo zinokwenzeka, kwaye imibala ibukhali kwaye icace ngakumbi njengoko kungekho kufunxeka kwindawo yoshicilelo: ukukhetha ushicilelo lwe-UV kuneendlela zoshicilelo zesintu kunokuba ngumahluko phakathi kokuvelisa imveliso yodidi oluphezulu, kunye nento eziva ingaphantsi kakhulu.
Ii-inki zikwaphuculwe iimpawu zomzimba, ukugqiba kweglosi ephuculweyo, ukukrwela ngcono, iikhemikhali, ukunyibilika kunye nokuqina kokuqina, ukunwebeka okungcono kunye nemveliso yokugqiba ikwaxhamla kumandla aphuculweyo.Zikwahlala ixesha elide kwaye zixhathisa imozulu, kwaye zinika ukomelela okwandisiweyo ekuphelelweni kuzenza zilungele imiqondiso yangaphandle.Inkqubo iphinda ingabizi kakhulu - iimveliso ezininzi zinokuprintwa ngexesha elincinci, kumgangatho ongcono kunye nokukhatywa okumbalwa.Ukunqongophala kwee-VOC ezikhutshwayo phantse kuthetha ukuba akukho monakalo omncinane kwindalo esingqongileyo kwaye umsebenzi uzinzile.
