Siyazi ukuthi izingubo ezindala ezimhlophe nezinto eziphrintiwe, isitashi esikhuntile, nezinhlamvu ngokuvamile zikhipha ukukhanya okuphuzi, okwenza abantu bazizwe 'bephuzi'.Uma inani elifanele le-ejenti emhlophe ye-fluorescent lengezwa ngalesi sikhathi, leziama-fluorescent whitening agentsizokhipha ukukhanya okuluhlaza okwesibhakabhaka noma okunsomi okwesibhakabhaka ngemva kokumunca imisebe ye-ultraviolet engabonakali, yenze umbala ohambisanayo nokukhanya okuphuzi okuthwalwa into ngokwayo, ngaleyo ndlela iqede into yokuqala “ephuzi” futhi yenze izingubo nezinto eziphrintiwe ekuqaleni ezazibukeka ziyisidala. avele amhlophe njengokusha (qaphela: ukwengeza izikhanyisi ze-fluorescent kusitashi esikhuntile futhi okusanhlamvu akukho emthethweni!).Lesi yisimiso sokwenza mhlophe kwama-agent amhlophe e-fluorescent.Kalula nje, i-agent emhlophe ye-fluorescentI-CBS-Xisebenzisa umbala obonakalayo ukwenza mhlophe, kukhanye, noma kukhanye izinto ezimhlophe noma ezinemibala ekhanyayo.Ayihlanganisi noma yikuphi ukusabela kwamakhemikhali ngento, kodwa incike kuphela esenzweni sokubona ukukhulisa ubumhlophe bento.Ngakho-ke, i-ejenti emhlophe ye-fluorescent ye-CBS-X yaziwa nangokuthi "i-agent emhlophe yokubona" noma "udayi omhlophe".
Ingabe ubukhona be-fluorescence busho ukungezwa kwe-agent emhlophe ye-fluorescent CBS-X?
Njengoba kushiwo ngenhla, i-fluorescence phenomenon isenzakalo esibonakalayo esingase sivele ezintweni ezivamile ze-fluorescent, ezifana ne-fluorescein kuma-fireflies;Kungase futhi kube nezinto ezihlukahlukene ze-fluorescent ezisuselwe ekubunjweni kokwenziwa, okufana noyinki we-fluorescent, ama-fluorescent coatings, amapeni e-fluorescent, amapulasitiki e-fluorescent, nezinye izinto okusolakala ukuthi ziyizinto ezisebenza ngokukhanya okukhanyayo, kanye nama-ejenti amhlophe e-fluorescent.I-Fluorescent whitening agents iwuhlobo olukhethekile kuphela lwento ye-fluorescent enemiphumela emhlophe nekhanyayo phakathi kwezinto ezihlukahlukene eziyinkimbinkimbi ze-fluorescent.Ngakho-ke, uma sikhuluma ngokuqinile, izinto ze-fluorescent azilingani nezikhanyisi ze-fluorescent, futhi ukubuka izenzakalo ze-fluorescence akusho ngempela ukungezwa kwezibani ze-fluorescent !!!
Isenzakalo se-fluorescence ≠ ukuba khona kweumenzeli omhlophe we-fluorescent CBS-X
Izibani ezikhanyayo ze-fluorescent zikhiqiza izenzakalo ze-fluorescence (ngamaza amaza athile)
Njengezithako zokudla, izinhlobonhlobo zezikhanyisi ze-fluorescent ziyinkimbinkimbi.Ngokusetshenziswa, ihlukaniswe izikhanyisi ze-fluorescent zokwenza iphepha, amapulasitiki nezinto zokwakha, izindwangu, okokuhlanza, oyinki, okunamathelayo nokunye ukusetshenziswa.
Ngokokuhlukaniswa kwezakhiwo ze-ionic, izikhanyisi ze-fluorescent zingaphinde zihlukaniswe zibe izikhanyisi ezingezona i-ionic, izikhanyisi ze-anionic, izikhanyisi ze-cationic, nezikhanyisi ze-amphoteric.
Ngokwesakhiwo samakhemikhali, ingahlukaniswa izigaba ezinhlanu: uhlobo lwe-stilbene, uhlobo lwe-coumarin, uhlobo lwe-pyrazoline, uhlobo lwe-benzoxazole, nohlobo lwe-phthalimide imide.
Ngokuvumelana ne-solubility yamanzi, ingahlukaniswa izigaba ezimbili: inyibiliki yamanzi kanye ne-insoluble.Ama-ejenti amhlophe e-fluorescent ancibilikayo emanzini asetshenziselwa ikakhulukazi ukwenza amaphepha abe mhlophe, okokuhlanganisa, okokuhlanza izingubo, nezindwangu zikakotini, kuyilapho ama-ejenti amhlophe e-fluorescent angancibiliki esetshenziselwa imikhiqizo yokwenza mhlophe njengemicu yamakhemikhali namapulasitiki.
Njengamanje, kukhona cishe ukumiswa kwamakhemikhali ayi-15 kanye nezikhanyisi ze-fluorescent ezingaphezu kuka-400.Ngemva kweminyaka yokukhuculula isihlabathi, ezinye seziphelile, futhi manje kunenqwaba yezinhlobo ezivame ukusetshenziswa ezisakhiqizwa futhi zisetshenziswe emhlabeni.
