Izikhanyisi ze-Optical, ezaziwa ngokubaizikhanyisi ze-optical(OBAs), ziikhompawundi ezisetyenziselwa ukuphucula inkangeleko yezinto ngokwandisa ubumhlophe bazo kunye nokukhanya kwazo. Zisetyenziswa kakhulu kumashishini ahlukeneyo, kuquka amalaphu, amaphepha, izicoci kunye neeplastiki. Kweli nqaku, siza kuhlola ukuba ziintoni izikhanyisi ze-optical, indlela ezisebenza ngayo, kunye nokusetyenziswa kwazo ezahlukeneyo.

Izikhanyisi ze-Optical zisebenza ngokufunxa ukukhanya kwe-ultraviolet (UV) kwaye ziphinde zikhuphe njengokukhanya okubonakalayo kwi-blue-violet spectrum. Le nto ibizwa ngokuba yi-fluorescence. Ngokuguqula imisebe ye-UV ibe kukukhanya okubonakalayo, izikhanyisi ze-optical ziphucula ukuqaqamba kunye neempawu ze-fluorescent zezinto, zizenze zibonakale zikhanya kwaye zimhlophe ngakumbi.

Ukusetyenziswa okuqhelekileyo kwezikhanyisi ze-optical kukwishishini lempahla. Kwimpahla, izikhanyisi ze-optical zongezwa kwimpahla kunye neefayibha ukuphucula imbonakalo yazo. Xa impahla okanye amalaphu aphathwe ngezikhanyisi ze-optical evezwa elangeni okanye ekukhanyeni okwenziweyo, afunxa imisebe ye-UV ekhoyo kwaye akhuphe ukukhanya okubonakalayo, okwenza impahla ibonakale imhlophe kwaye ikhanya ngakumbi. Esi siphumo sithandeka ngakumbi kwimpahla emhlophe okanye enemibala ekhanyayo, siphucula ucoceko kunye nobutsha bayo.

Elinye ishishini elisebenzisa kakhulu izikhanyisi ze-optical yishishini lephepha. Izikhanyisi ze-optical zongezwa ngexesha lenkqubo yokwenziwa kwephepha ukuze kwandiswe ukukhanya kwalo kwaye lenze libonakale limhlophe ngakumbi. Ngokwandisa ubumhlophe bephepha,izikhanyisi ze-opticalzinceda ekuveliseni iiprinti kunye nemifanekiso esemgangathweni ophezulu. Zikwanceda ekunciphiseni ubungakanani beinki efunekayo ekuprinteni, nto leyo ekhokelela ekongeni iindleko kwiinkampani zokushicilela kunye nabathengi.

Izikhanyisi ze-optical zikwafumaneka kakhulu kwiisepha zokuhlamba impahla. Zongezwa kwiifomyula zesepha ukuze zenze ezimhlophe zibonakale zimhlophe kwaye imibala iqaqambe ngakumbi. Xa impahla ihlanjwa ngeesepha ezinezikhanyisi ze-optical, ezi zinto zifakwa kumphezulu welaphu, zifunxa imisebe ye-ultraviolet kwaye zikhuphe ukukhanya okuluhlaza okwesibhakabhaka, zigqume umbala otyheli kwaye zonyusa ukukhanya kwempahla iyonke. Oku kugcina impahla icocekile kwaye intsha, nokuba sele ihlanjwe kaninzi.

Ukwengeza,izikhanyisi ze-opticalzikwasetyenziswa nakwimveliso yeplastiki. Zongezwa kwiplastiki ngexesha lenkqubo yokuvelisa ukuphucula inkangeleko yayo nokuyenza ibonakale inomtsalane ngakumbi. Iimveliso zeplastiki ezifana neebhotile, izikhongozeli kunye nezinto zokupakisha eziphathwe ngee-optical brighteners zibonakala zikhanya kwaye zinomtsalane ngakumbi kwiishelufu zevenkile. Ukusebenzisa ii-optical brighteners kwiplastiki kunokunceda ukufihla naziphi na iziphene okanye ukutyheli okunokuvela ngokuhamba kwexesha ngenxa yokuvezwa lilanga okanye izinto ezingqongileyo.

Ngamafutshane, izikhanyisi ze-optical ziikhompawundi ezisetyenziswa kakhulu kumashishini ahlukeneyo ukuphucula ubumhlophe kunye nokukhanya kwezinto. Ngokufunxa ukukhanya kwe-ultraviolet kunye nokuyiphinda ikhuphe njengokukhanya okubonakalayo, izikhanyisi ze-optical zinceda ukuphucula ukubonakala kwempahla, iphepha, isepha kunye neeplastiki. Zibalulekile ekufezekiseni iimpawu zobuhle kunye nokubona ezifunekayo kwezi zinto. Nokuba zenza amalaphu abonakale ecocekile, imifanekiso yamaphepha ibonakale ibukhali, okanye iiplastiki zibonakale zinomtsalane ngakumbi, izikhanyisi ze-optical zidlala indima ebalulekileyo ekuphuculeni amava okubona ngokubanzi.
