Ukuphrinta kwe-UV kuyindlela eyingqayizivele yeukuphrinta kwedijithalikusetshenziswa ukukhanya kwe-ultraviolet (UV) ukomisa noma ukwelapha uyinki, izinto ezinamathelayo noma okokunamathisela cishe ngokushesha nje lapho ishaya ephepheni, noma i-aluminium, ibhodi legwebu noma i-acrylic - empeleni, inqobo nje uma ingena kuphrinta, le ndlela ingasetshenziswa phrinta cishe noma yini.
Inqubo yokwelapha nge-UV - inqubo ye-photochemical yokomisa - ekuqaleni yethulwa njengendlela yokomisa ngokushesha i-gel nail polishes esetshenziswa ekuzilungiseni izinwele, kodwa isanda kwamukelwa yimboni yokunyathelisa lapho isetshenziselwa ukuphrinta kunoma yini evela ezimpawu nezincwajana. emabhodleleni kabhiya.Inqubo iyafana nokuphrinta kwendabuko, umehluko kuphela yiyinki esetshenzisiwe kanye nenqubo yokomisa - kanye nemikhiqizo ephakeme ekhiqizwayo.
Ekunyatheliseni kwendabuko, kusetshenziswa oyinki be-solvent;lezi zingahwamuka futhi zikhiphe izinhlanganisela eziphilayo ezishintshashintshayo (VOCs) eziyingozi emvelweni.Indlela iphinde ikhiqize - futhi isebenzise - ukushisa kanye nephunga elihambisanayo.Ngaphezu kwalokho, kudinga izimpushana zesifutho ezengeziwe ukusiza ngenqubo yokususa uyinki nokomisa, okungathatha izinsuku ezimbalwa.Oyinki bamuncwa endaweni yokuphrinta, ngakho imibala ingabonakala igezekile futhi isifiphele.Inqubo yokunyathelisa ilinganiselwe kakhulu ezintweni zephepha nezamakhadi, ngakho-ke ayikwazi ukusetshenziswa ezintweni ezifana nepulasitiki, ingilazi, insimbi, i-foil noma i-acrylic efana nokuphrinta kwe-UV.
Ekuphrinteni kwe-UV, i-mercury/quartz noma izibani ze-LED zisetshenziselwa ukwelapha esikhundleni sokushisa;ukukhanya kwe-UV okunamandla aphezulu okuklanywe ngokukhethekile kulandele eduze njengoba uyinki okhethekile usatshalaliswa endaweni yokunyathelisa, yomiswe ngokushesha ngemva kokuba ifakwe.Ngenxa yokuthi uyinki uyashintsha usuke ekubeni oqinile noma unamathisele uye ekubeni oketshezi ngokushesha, alikho ithuba lokuthi uhwamuke ngakho awekho ama-VOC, intuthu enobuthi noma i-ozone ekhishwayo, okwenza ubuchwepheshe buhambisane nemvelo cishe cishe ne-zero carbon footprint.
Uyinki, into enamathelayo noma enamathelayo iqukethe ingxube yama-monomers awuketshezi, ama-oligomers - ama-polymers ahlanganisa amayunithi ambalwa aphindayo - nama-photoinitiators.Ngesikhathi senqubo yokwelapha, ukukhanya okunamandla aphezulu engxenyeni ye-ultraviolet ye-spectrum, enobude obuphakathi kuka-200 no-400 nm, kudonswa i-photoinitiator ebhekana nokusabela kwamakhemikhali - ukuxhumanisa kwamakhemikhali - futhi kubangela uyinki, ukunamathela noma ukunamathela qina khona manjalo.
Kulula ukubona ukuthi kungani ukuphrinta kwe-UV kudlule emanzini endabuko kanye nezindlela zokumisa ezishisayo ezisekelwe ku-solvent nokuthi kungani kulindeleke ukuthi kuqhubeke ukukhula ekudumeni.Indlela ayisheshi nje kuphela ukukhiqiza - okusho ukuthi okuningi kwenziwa ngesikhathi esincane - amazinga okunqatshwa ayancishiswa njengoba ikhwalithi iphezulu.Amaconsi kayinki amanzi ayasuswa, ngakho-ke akukho ukuhlikihla noma ukuhlambalaza, futhi njengoba ukomisa cishe kuseduze, akukho ukuhwamuka futhi ngakho-ke akukho ukulahlekelwa kokuqina noma ivolumu.Imininingwane emihle ingenzeka, futhi imibala ibukhali futhi icace kakhulu njengoba kungekho ukumuncwa endaweni yokuphrinta: ukukhetha ukuphrinta kwe-UV kunezindlela zokuphrinta ezijwayelekile kungaba umehluko phakathi kokukhiqiza umkhiqizo owubukhazikhazi, kanye nento ezizwa ingcono kakhulu.
Oyinki babuye babe nezakhiwo ezithuthukisiwe zomzimba, isicwebezelisi esithuthukisiwe, ukuklwebheka okungcono, amakhemikhali, ukumelana ne-solvent nobulukhuni, ukunwebeka okungcono kanye nomkhiqizo wokuqeda nawo uyazuza emandleni athuthukisiwe.Zihlala isikhathi eside futhi zimelana nesimo sezulu, futhi zinikeza ukumelana okwenyukayo kokufiphala okuzenza zilungele izimpawu zangaphandle.Inqubo nayo ibiza kakhulu - imikhiqizo eminingi ingaphrintwa ngesikhathi esincane, ngekhwalithi engcono futhi ngokunqatshwa okumbalwa.Ukuntuleka kwama-VOC akhishwa cishe kusho ukuthi kunomonakalo omncane endaweni ezungezile futhi umkhuba uzinzile.
