izindaba

Lapho ingaphansi kokukhanya okubonakalayo, i-UV fluorescent powder imhlophe noma icishe ikhanye, ijatshuliswe ngamaza ahlukene (254nm, 365 nm) ikhombisa umbala owodwa noma ngaphezulu we-fluorescent,Okuyinhloko

umsebenzi ukuvimbela abanye ekwenzeni umgunyathi.Iwuhlobo lwe-pigment enobuchwepheshe obuphezulu, nombala omuhle ofihliwe..

Sikhiqiza izinhlobo ezimbili: i-organic phosphors & ne-inorganic phosphors

I-organic phosphors: Ebomvu, ephuzi-luhlaza, ephuzi, eluhlaza okwesibhakabhaka.

B ama-phosphor angaphili: Obomvu, ophuzi-luhlaza, oluhlaza okotshani, oluhlaza okwesibhakabhaka, omhlophe, onsomi.

Indlela yokuphrinta ye-UV fluorescent security pigments

Ukuphrinta kwe-Offset, ukuphrinta kwesikrini, ukuphrinta kwe-intaglio nokuphrinta kwe-flexographic.

Ukusetshenziswa kwe-UV fluorescent security pigments

I-UV fluorescent security pigments Ingangezwa ngokuqondile kuyinki, upende, ukwakha umphumela wokuphepha we-fluorescent, isilinganiso esiphakanyisiwe sika-1% kuya ku-10%, singangezwa ngokuqondile ezintweni zepulasitiki.

ngokukhipha umjovo, isilinganiso esiphakanyisiwe sika-0.1% kuya ku-3%.

1.ingasetshenziswa kumapulasitiki ahlukahlukene afana ne-PE, PS, PP, ABS, acrylic, urea, melamine, polyester I-resin enombala we-fluorescent.

I-2.Ink: yokumelana okuhle kwe-solvent futhi akukho ukushintsha kombala kokuphrinta komkhiqizo oqediwe akungcolisi.

I-3.Paint: ukumelana nomsebenzi we-optical kunamandla aphindwe kathathu kunezinye izinhlobo, i-fluorescence ekhanyayo ehlala isikhathi eside ingasetshenziswa ekukhangiseni nasekuvikelekeni kokunyathelisa okugcwele kwesixwayiso.
