ʻO ka pauka fluorescent UV, i ʻike ʻia hoʻi ʻo ultraviolet photoluminescent pigment, he puaʻa fluorescent i hana ʻia e ka calcining metala (zinc, cadmium) sulfides a i ʻole nā ​​mea ʻona honua ʻokoʻa me ka nui o nā surfactants. ʻO ke kala ʻole a i ʻole ke keʻokeʻo māmā e pili ana i ke kukui ʻike ʻia (400-800nm) i ʻike ʻia i nā kala like ʻole ma muli o ke ʻano a me ka ʻike o nā metala a me nā mea hoʻoulu i ka puaʻa ma lalo o ke kukui ultraviolet (200-400nm) irradiation. E like me nā hawewe ʻokoʻa o ke kumu kukui hoʻohiwahiwa, hiki ke hoʻokaʻawale ʻia i loko o ka nalu pōkole ultraviolet excited fluorescent pigments (excitation wavelength o 254nm) a me ka nalu lōʻihi ultraviolet excited fluorescent pigments (excitation wavelength o 365nm). ʻIke ʻia kēia ʻano huahana keʻokeʻo a ʻaneʻane ʻālohilohi paha ma lalo o nā kumu kukui ʻike ʻia, a hōʻike i hoʻokahi a ʻoi aku paha nā kala fluorescent ma lalo o nā kumu kukui lōʻihi hawewe like ʻole (254nm, 365nm, 850nm). Hoʻokomo ʻia ka pauda fluorescent i nā hopena kūikawā e like me ka organik, inorganic, a me ka afterglow, me nā waihoʻoluʻu ʻālohilohi. He ʻano kala like ʻole ka UV anti-counterfeiting fluorescent powder series, me ka ʻulaʻula, poni, melemele ʻōmaʻomaʻo, uliuli, ʻōmaʻomaʻo, melemele, keʻokeʻo, uliuli-'ōmaʻomaʻo, ʻalani, a ʻeleʻele. Hoʻohui kala like ʻole, hoʻololi pau ʻole, anti-counterfeiting fluorescent powder.ʻO ka pauka fluorescent inorganic:

A. He ʻālohilohi ke kala fluorescent a he mana uhi maikaʻi kona (me ka ʻole o ka pono o nā mea opaque).
B. He maikai a spherical na mea liilii, hiki ke hoolahaia, me ke anawaena o 1-10u no 98%.
C. ʻO ke kūpaʻa wela maikaʻi: ʻO 600amp # 176C ka palena kiʻekiʻe loa, kūpono no nā ʻano hana wela kiʻekiʻe. ʻO ke kūpaʻa o ka solvent maikaʻi, ka pale ʻana i ka waikawa, ke kūpaʻa alkali, a me ke kūpaʻa kiʻekiʻe.
D. ʻAʻohe hoʻololi kala, ʻaʻohe haumia.
E. ʻAʻole ʻawaʻawa, ʻaʻole e kahe ka formalin i ka wā e wela ai, hiki ke hoʻohana ʻia no ke kala ʻana i nā mea pāʻani a me nā ipu meaʻai.
F. ʻAʻole e kahe ke kino kala, hiki ke mālama i nā kaʻina hana hoʻomaʻemaʻe i ka wā e hoʻololi ai i ka ʻōpala i loko o ka mīkini injection.

ʻO ka pauka fluorescent organik:

A. ʻO ka'ōniʻoniʻo he'ālohilohi a nele i ka mana uhi, me ka māmā o ke komoʻana ma luna o 90%. Hiki ke hoʻoheheʻe maikaʻi, hiki ke hoʻoheheʻe nā ʻano mea ʻaila a pau, akā ʻokoʻa ka solubility, no laila pono e koho ʻia e like me nā pono like ʻole i ka wā e hoʻohana ai.
B. No ka moʻo kala, pono e nānā i nā pilikia hoʻololi kala.
D. Ma muli o ka maikaʻi ʻole o ka wā, pono e hoʻohui ʻia nā stabilizer ʻē aʻe i ka wā e hoʻohana ai.
E Heat resistance: ʻO ka wela wela loa he 200amp # 176C, kūpono no ka hana wela wela i loko o 200amp # 176C

Wahi noi

1. Hiki ke hoʻohana ʻia no ke kaha kiʻi ʻana i nā wahi hoʻokipa, e kiʻi ana ma lalo o ke kukui UV. 2. E hana i ka inika kūʻē i ka hoʻopunipuni, ka pena kūʻē i ka hoʻopunipuni, a me nā pale pale hoʻopunipuni.
3. E ho'āʻo i ka maikaʻi o ka huahana
4. Long wave fluorescence anti-counterfeiting technology is a advanced anti-counterfeiting technology i kēia manawa i hoʻohana ʻia i nā bila a me nā kālā, me ka hūnā maikaʻi a me nā mea ʻike kaulana loa (ua hoʻohana pinepine ʻia nā mea ʻike kālā ma nā hale kūʻai a me nā panakō no ka ʻike). Hoʻohana ka ʻenehana anti-counterfeiting hawewe pōkole i nā mea hana kūikawā no ka ʻike ʻana, no laila e ʻoi aku ka ikaika o ka anti-counterfeiting a me ka hana huna. Fluorescent ikeike ole ultraviolet excitation phosphor. Hōʻike kēia phosphor i ka fluorescence nani ma lalo o ka ultraviolet irradiation a hoʻohana nui ʻia no ka anti-counterfeiting. Loaʻa iā ia nā hiʻohiʻona o ka ʻenehana kiʻekiʻe a me ka hūnā kala maikaʻi.
