Impushana ye-UV fluorescent, eyaziwa nangokuthi i-ultraviolet photoluminescent pigment, i-pigment ye-fluorescent eyenziwe nge-calcining metal (zinc, cadmium) sulfide noma ama- earth oxides angavamile anamanani omkhondo wezinto eziphuma emanzini. Okumhlophe okungenambala noma okukhanyayo kubhekisela ekukhanyeni okubonakalayo (400-800nm) okuvela ngemibala ehlukahlukene kuye ngohlobo nokuqukethwe kwezinsimbi nezicupha kumbala ongaphansi kokukhanya kwe-ultraviolet (200-400nm) kwemisebe. Ngokuya ngamaza ahlukene omthombo wokukhanya ovusa amadlingozi, ingahlukaniswa ibe igagasi elifushane le-ultraviolet excited fluorescent pigments (excitation wavelength engu-254nm) kanye ne-wave long ultraviolet excited pigments fluorescent (excitation waveleng of 365nm). Lolu chungechunge lwemikhiqizo lubonakala lumhlophe noma lucishe lukhanye ngaphansi kwemithombo yokukhanya ebonakalayo, futhi lubonisa umbala we-fluorescent owodwa noma ngaphezulu ngaphansi kwemithombo yokukhanya ehlukene yamaza amaza (254nm, 365nm, 850nm). Izimpushana ze-fluorescent zihlanganisa imiphumela ekhethekile efana ne-organic, inorganic, kanye ne-afterglow, enemibala egqamile nekhanyayo. Imikhiqizo yochungechunge lwe-UV anti-counterfeiting fluorescent powder inemibala ehlukahlukene, ehlanganisa obomvu, onsomi, oluhlaza ophuzi, oluhlaza okwesibhakabhaka, oluhlaza okotshani, ophuzi, omhlophe, oluhlaza okwesibhakabhaka, owolintshi, nomnyama. Inhlanganisela yemibala eyahlukahlukene, ukuhluka okungapheli, impushana ye-fluorescent ephikisana nomgunyathi.Inorganic fluorescent powder:

A. Umbala we-fluorescent uyakhanya futhi unamandla okuvala amahle (ngaphandle kwesidingo sama-opaque agents).
B. Izinhlayiya zilungile futhi ziyindilinga, zihlakazeka kalula, ezinobubanzi obungaba ngu-1-10u ku-98%.
C. Ukumelana nokushisa okuhle: Ukushisa okuphezulu kokumelana ngu-600amp # 176C, kulungele ukucutshungulwa okuhlukahlukene kwezinga lokushisa eliphezulu. Ukumelana okuhle kwe-solvent, ukumelana ne-asidi, ukumelana ne-alkali, nokuzinza okuphezulu.
D. Akukho ukushintsha kombala, akukho ukungcola.
E. Ayinabuthi, ayichithi i-formalin uma ifudunyezwa, ingasetshenziselwa ukufaka imibala kwamathoyizi neziqukathi zokudla.
F. Umzimba wombala ngeke ugcwale, ongagcina izinqubo zokuhlanza lapho ushintsha isikhunta ngaphakathi komshini womjovo.

I-organic fluorescent powder:

A. Umbala we-fluorescent uyagqama futhi awunawo amandla okuvala, nesilinganiso sokukhanya sokungena esingaphezu kuka-90%. I-solubility enhle, zonke izinhlobo zezincibilikisi ezinamafutha zingancibilika, kodwa ukuncibilika kuhlukile, ngakho-ke kudinga ukukhethwa ngokuvumelana nezidingo ezahlukene uma usebenzisa.
B. Okuyingxenye yochungechunge lukadayi, kufanele kuqashelwe izinkinga zokushintsha umbala.
D. Ngenxa yokungazweli kahle kwesimo sezulu, ezinye iziqinisi kudingeka zengezwe ngesikhathi sokusetshenziswa.
E Ukumelana nokushisa: Ukushisa okuphezulu kokumelana ngu-200amp # 176C, kulungele ukucubungula izinga lokushisa eliphezulu ngaphakathi kwe-200amp # 176C

Indawo Yesicelo

1. Ingasetshenziselwa ukudweba ezindaweni zokuzijabulisa, ukudweba ngaphansi kokukhanya kwe-UV. 2. Khiqiza uyinki omelene nomgunyathi, upende omelene nomgunyathi, kanye nezindwangu zokulwa nomgunyathi
3. Yenza ukuhlolwa kwekhwalithi yomkhiqizo
4. Ubuchwepheshe bokulwa nomgunyathi obuyi-long wave fluorescence buwubuchwepheshe obuthuthukisiwe bokulwa nomgunyathi okwamanje obusetshenziswa ezikweletini nasezindaweni zemali, obunokucasha okuhle kanye nezisetshenziswa zokuhlonza ezidumile uma kuqhathaniswa (izitholi zemali zivame ukusetshenziswa ezitolo ezinkulu nasemabhange ukuze zihlonzwe). Ubuchwepheshe bokulwa nokukhwabanisa kwegagasi elifushane busebenzisa amathuluzi akhethekile ukuze kukhonjwe, ngaleyo ndlela kube nokusebenza okuqinile kokulwa nomgunyathi nokufihla. I-Fluorescent engabonakali ye-ultraviolet excitation phosphor. Le phosphor ibonisa i-fluorescence ekhazimulayo ngaphansi kwemisebe ye-ultraviolet futhi isetshenziselwa kakhulu ukulwa nokukhwabanisa. Inezici zokuqukethwe okuphezulu kwezobuchwepheshe kanye nokufihla umbala omuhle.
