Itekhnoloji yokunyanga ye-UV iye yaliguqula ishishini loshicilelo, ibonelela ngamaxesha akhawulezayo okunyanga, ukwanda kwemveliso kunye nokunciphisa ukusetyenziswa kwamandla.Nangona kunjalo, ubukho beoksijini ngexesha lenkqubo yokunyanga bunokuba nempembelelo enkulu ekusebenzeni kwe-UV yokunyanga ii-inki.
Ukuvinjelwa kwe-oksijeni kwenzeka xa iimolekyuli ze-oksijini ziphazamisa i-polymerization ye-radical yamahhala, okubangelwa ukunyanga okungaphelelanga kunye nokusebenza kwe-inki ephazamisayo.Lo mcimbi uvakaliswa ngokukodwa kwii-inki ezibhityileyo kwaye zinendawo ephezulu yokulinganisa umthamo.
Xa ii-inki ezinyangekayo ze-UV zibonakaliswe kumoya okhoyo, iimolekyuli ze-oksijini ezinyityilisiweyo kwi-inki ye-inki kunye ne-oxygen esasazwe emoyeni inokuphazamisa inkqubo ye-polymerization.I-concentration ephantsi ye-oksijini enyibilikisiweyo isetyenziswe lula yi-reactive radicals yamahhala, ekhokelela kwixesha lokungeniswa kwe-polymerization.Ngakolunye uhlangothi, i-oksijini ehlala isasazeka kwi-inki evela kwindawo yangaphandle iba yimbangela ephambili yokuthintela.
Imiphumo ye-oxygen inhibition ingabandakanya ixesha elide lokunyanga, ukunamathela komphezulu kunye nokwakhiwa kwezakhiwo ze-oxidized kwi-inkinki.Ezi ziphumo zinokunciphisa ubunzima, i-gloss kunye nokuxhatshazwa kwe-scratch ye-inki ephilileyo kwaye ichaphazela ukuzinza kwayo kwexesha elide.
Ukoyisa le mingeni, abaphandi kunyeAbavelisi be-UV LEDbaye baphonononga izicwangciso ezahlukeneyo.
Eyokuqala kukutshintsha indlela yokusabela.Ngokuphucula inkqubo ye-photoinitiator, inhibition ye-oksijini yendawo ye-inki ephilileyo inokucinezelwa ngokufanelekileyo.
Ukwandisa i-concentration of photoinitiators yenye indlela yokunciphisa imiphumo yokuthintela i-oxygen.Ngokongeza ii-photoinitiators ezininzi, ukubunjwa kwe-inki kuba nzima ngakumbi kwi-oxygen inhibition.Oku kubangela ubulukhuni be-inki ephezulu, ukunamathela okungcono kunye neglosi ephezulu emva kokunyanga.
Ukongeza, ukonyusa ukuqina kwesixhobo sokunyanga i-UV kwisixhobo sokunyanga kunceda ukunciphisa iziphumo ezibi zokuthintela ioksijini.Ngokwandisa amandla omthombo wokukhanya kwe-UV, inkqubo yokunyanga iba yinto esebenzayo kwaye ihlawulela ukuphinda kusebenze okucuthiweyo okubangelwa kukuphazamiseka kwe-oksijini.Eli nyathelo kufuneka lilinganiswe ngononophelo ukuze kuqinisekiswe unyango olululo ngaphandle kokonakalisa i-substrate okanye kubangele ezinye iziphumo ezibi.
Okokugqibela, inhibition yeoksijini inokuncitshiswa ngokongeza enye okanye ngaphezulu kwe-oxygen scavenger kwisixhobo sokushicilela.Ezi scavengers zisabela nge-oxygen ukunciphisa ukugxila kwayo, kunye nokudityaniswa kokuqina okuphezuluInkqubo yokunyanga ye-UV ye-LEDkunye ne-oxygen scavenger inokunciphisa impembelelo ye-oksijini kwinkqubo yokunyanga.Ngolu phuculo, abavelisi banokufezekisa ukusebenza kakuhle kokunyanga kwaye banqobe imingeni yokuthintela i-oxygen.
