Ukuphrinta kwe-UV kuyindlela ehlukileukuphrinta kwedijithalikusetshenziswa ukukhanya kwe-ultraviolet (UV) ukuze komise noma kupholise uyinki, izinamathiseli noma izembozo cishe ngokushesha nje lapho ifika ephepheni, noma i-aluminium, ibhodi le-foam noma i-acrylic - empeleni, uma nje ingena kuphrinta, le ndlela ingasetshenziswa ukuphrinta cishe kunoma yini.
Indlela yokwelapha nge-UV – inqubo yokomisa esebenzisa i-photochemical – yaqalwa njengendlela yokomisa ngokushesha ama-gel nail polishes asetshenziswa ekwenzeni i-manicure, kodwa muva nje yamukelwa imboni yokunyathelisa lapho isetshenziswa khona ukunyathelisa kunoma yini kusukela ezimpawini nasezincwajana kuya emabhodleleni kabhiya. Le nqubo ifana nokunyathelisa kwendabuko, umehluko kuphela uyinki esetshenziswayo kanye nenqubo yokomisa – kanye nemikhiqizo emihle kakhulu ekhiqizwayo.
Ekunyatheliseni okuvamile, kusetshenziswa uyinki we-solvent; lokhu kungahwamuka futhi kukhiphe ama-volatile organic compounds (ama-VOC) ayingozi emvelweni. Le ndlela ikhiqiza futhi - futhi isebenzisa - ukushisa kanye nephunga elihambisana nayo. Ngaphezu kwalokho, idinga ama-spray powder engeziwe ukusiza ngenqubo yokususa uyinki nokomisa, okungathatha izinsuku eziningana. Uyinki umuncwa endaweni yokunyathelisa, ngakho imibala ingabonakala ihlanziwe futhi ifiphele. Inqubo yokunyathelisa inqunyelwe kakhulu ephepheni nasemakhadini, ngakho-ke ayikwazi ukusetshenziswa ezintweni ezifana nepulasitiki, ingilazi, insimbi, i-foil noma i-acrylic njengokunyathelisa kwe-UV.
Ekuphrinteni kwe-UV, izibani ze-mercury/quartz noma ze-LED zisetshenziselwa ukupholisa esikhundleni sokushisa; ukukhanya kwe-UV okuklanywe ngokukhethekile kulandela eduze njengoba uyinki okhethekile usatshalaliswa endaweni yokuphrinta, uyomisa ngokushesha nje lapho usetshenziswa. Ngenxa yokuthi uyinki uguquka kusuka ekubeni yinto eqinile noma enamathelayo ibe uketshezi cishe ngokushesha, awekho amathuba okuba uphele futhi ngakho-ke awekho ama-VOC, umusi onobuthi noma i-ozone ekhishwayo, okwenza ubuchwepheshe bube nobungane nemvelo cishe ngaphandle kwe-carbon footprint.
Uyinki, ingcina noma i-coating iqukethe ingxube yama-monomers ewuketshezi, ama-oligomers – ama-polymer aqukethe amayunithi ambalwa aphindaphindayo – kanye nama-photoinitiators. Ngesikhathi senqubo yokwelapha, ukukhanya okunamandla aphezulu engxenyeni ye-ultraviolet ye-spectrum, enobude be-wavelength obuphakathi kuka-200 no-400 nm, kumuncwa yi-photoinitiator edlula ekusabela kwamakhemikhali – ukuxhumanisa kwamakhemikhali – futhi ibangele ukuthi uyinki, i-coating noma i-coating iqine ngokushesha.
Kulula ukubona ukuthi kungani ukuphrinta kwe-UV kudlule izindlela zokomisa ezisebenzisa amanzi kanye ne-solvent nokuthi kungani kulindeleke ukuthi kuqhubeke nokukhula ngokuthandwa. Le ndlela ayisheshisi nje kuphela ukukhiqizwa - okusho ukuthi kwenziwa okuningi ngesikhathi esincane - amazinga okwenqatshwa ayancishiswa njengoba ikhwalithi iphezulu. Amaconsi amanzi kayinki ayasuswa, ngakho-ke akukho ukukhuhla noma ukufiphala, futhi njengoba ukomisa kucishe kube ngokushesha, akukho ukuhwamuka ngakho-ke akukho ukulahleka kobukhulu noma ivolumu yokumboza. Imininingwane emihle kakhulu ingenzeka, futhi imibala ibukhali futhi icacile njengoba kungekho ukumuncwa endaweni yokunyathelisa: ukukhetha ukuphrinta kwe-UV kunezindlela zokunyathelisa zendabuko kungaba umehluko phakathi kokukhiqiza umkhiqizo wobukhazikhazi, nokuthile okuzizwa kungaphansi kakhulu.
Oyinki nabo banezakhiwo ezibonakalayo ezithuthukisiwe, ukugqama okuthuthukisiwe, ukuklwebheka okungcono, ukumelana namakhemikhali, ukuncibilikisa kanye nokuqina, ukunwebeka okungcono kanti umkhiqizo wokugcina nawo uyazuza ngamandla athuthukisiwe. Futhi ahlala isikhathi eside futhi amelana nesimo sezulu, futhi anikeza ukumelana okukhulu nokufiphala okwenza kube kuhle kakhulu ezimpawini zangaphandle. Le nqubo nayo ingabizi kakhulu - imikhiqizo eminingi ingaphrintwa ngesikhathi esincane, ngekhwalithi engcono kanye nokunqatshwa okuncane. Ukuntuleka kwama-VOC akhishwayo cishe kusho ukuthi kunomonakalo omncane emvelweni futhi lo mkhuba uyaqhubeka.
phila okwengeziwe:
