Zotsatira za Kuletsa kwa Oxygen pa Magwiridwe a UV LED Kuchiritsa

Ukadaulo wamachiritso a UV wasintha ntchito yosindikiza, kupereka nthawi yochiritsa mwachangu, kuchuluka kwa zokolola komanso kuchepetsa kugwiritsa ntchito mphamvu.Komabe, kupezeka kwa okosijeni panthawi yochiritsa kumatha kukhudza kwambiri magwiridwe antchito a inki ya UV.

Kuletsa kwa okosijeni kumachitika pamene mamolekyu a okosijeni amasokoneza ma polymerization aulere, zomwe zimapangitsa kuchiritsa kosakwanira komanso kusokoneza ntchito ya inki.Chodabwitsa ichi chimatchulidwa makamaka mu inki zomwe zimakhala zoonda komanso zokhala ndi malo okwera pamwamba pa chiwerengero cha voliyumu.

Ma inki ochiritsika a UV akakhala ndi mpweya wozungulira, mamolekyu a okosijeni omwe amasungunuka mu inki komanso mpweya wotuluka mumlengalenga amatha kusokoneza momwe ma polymerization amagwirira ntchito.Mpweya wochepa wa okosijeni wosungunuka umadyedwa mosavuta ndi ma free radicals oyambira, zomwe zimapangitsa kuti pakhale nthawi yoyambitsa ma polymerization.Kumbali inayi, mpweya womwe umafalikira nthawi zonse mu inki kuchokera ku chilengedwe chakunja umakhala chifukwa chachikulu cholepheretsa.

Zotsatira za kuletsa kwa okosijeni zimatha kuphatikizira nthawi yayitali yochiritsa, kumamatira pamwamba komanso kupanga mapangidwe a okosijeni pamtunda wa inki.Zotsatirazi zimatha kuchepetsa kuuma, gloss ndi kukanika kukanika kwa inki yochiritsidwa ndikukhudza kukhazikika kwake kwanthawi yayitali.

Pofuna kuthana ndi mavutowa, ofufuza ndiOpanga ma LED a UVafufuza njira zosiyanasiyana.

Choyamba ndikusintha momwe zimakhalira.Mwa kuwongolera dongosolo la photoinitiator, kuletsa kwa oxygen pamtunda wa inki yochiritsidwa kumatha kuponderezedwa bwino.

Kuchulukitsa kuchuluka kwa ma photoinitiators ndi njira ina yochepetsera zotsatira za kuletsa kwa okosijeni.Powonjezera ma photoinitiators, mapangidwe a inki amakhala osagwirizana kwambiri ndi kuletsa kwa okosijeni.Izi zimabweretsa kulimba kwa inki, kumamatira bwino komanso kuwunikira kwambiri pambuyo pochiritsa.

Kuphatikiza apo, kukulitsa mphamvu ya zida zochiritsira za UV pazida zochiritsira kumathandizira kuchepetsa zotsatira zoyipa za kuletsa kwa okosijeni.Powonjezera mphamvu ya gwero la kuwala kwa UV, njira yochiritsira imakhala yogwira mtima kwambiri ndikulipiritsa kuchepa kwa reactivity chifukwa cha kusokoneza kwa okosijeni.Gawoli liyenera kuwunikiridwa mosamala kuti lichiritsidwe bwino popanda kuwononga gawo lapansi kapena kuyambitsa zovuta zina. 

Pomaliza, kuletsa kwa okosijeni kumatha kuchepetsedwa powonjezera chophatikizira chimodzi kapena zingapo za okosijeni ku zida zosindikizira.Ma scavenger awa amachitira ndi okosijeni kuti achepetse ndende yake, komanso kuphatikiza kwamphamvu kwambiriNjira yochiritsira ya UV ya LEDndi mpweya wa okosijeni ukhoza kuchepetsa mphamvu ya okosijeni pa njira yochiritsira.Ndizitukukozi, opanga amatha kupeza ntchito yabwino yochizira ndikugonjetsa zovuta za kulepheretsa mpweya.
