xov xwm

UV fluorescent hmoov, tseem hu ua ultraviolet photoluminescent pigment, yog fluorescent pigment ua los ntawm calcining hlau (zinc, cadmium) sulfides los yog tsis tshua muaj ntiaj teb oxides nrog cov kab ntawm surfactants. Tsis muaj xim lossis lub teeb dawb yog hais txog lub teeb pom kev (400-800nm) uas tshwm nyob rau hauv ntau xim nyob ntawm seb hom thiab cov ntsiab lus ntawm cov hlau thiab activators nyob rau hauv cov xim nyob rau hauv ultraviolet lub teeb (200-400nm) irradiation. Raws li qhov sib txawv wavelengths ntawm excitation lub teeb qhov chaw, nws yuav muab faib ua luv luv yoj ultraviolet zoo siab fluorescent pigments (excitation wavelength ntawm 254nm) thiab ntev yoj ultraviolet zoo siab fluorescent pigments (excitation wavelength ntawm 365nm). Cov khoom lag luam no tshwm sim dawb lossis ze li pob tshab hauv qhov pom lub teeb pom kev, thiab nthuav tawm ib lossis ntau xim fluorescent nyob rau hauv qhov sib txawv wavelength lub teeb (254nm, 365nm, 850nm). Cov hmoov fluorescent muaj cov teebmeem tshwj xeeb xws li cov organic, inorganic, thiab tom qab, nrog cov xim ci thiab ci. Cov khoom siv UV tiv thaiv fluorescent hmoov series muaj ntau yam xim, xws li liab, ntshav, daj, ntsuab, xiav, ntsuab, daj, dawb, xiav-ntsuab, txiv kab ntxwv, thiab dub. Ntau yam xim sib xyaw ua ke, kev hloov pauv tsis kawg, tiv thaiv cov khoom cuav fluorescent hmoov.Inorganic fluorescent hmoov:

A. Cov xim fluorescent yog ci thiab muaj lub zog npog zoo (tsis tas yuav muaj cov tshuaj opaque).
B. Cov khoom yog zoo thiab kheej kheej, yooj yim dispersed, nrog ib txoj kab uas hla ntawm 1-10u rau 98%.
C. Kev ua haujlwm kub zoo: Qhov siab tshaj plaws tiv taus kub yog 600amp # 176C, haum rau ntau yam kev ua haujlwm kub. Cov kuab tshuaj zoo, acid tsis kam, alkali tsis kam, thiab siab stability.
D. Tsis muaj xim hloov, tsis muaj kuab paug.
E. Tsis muaj tshuaj lom, tsis txeej formalin thaum tshav kub, tuaj yeem siv rau xim cov khoom ua si thiab ntim khoom noj.
F. Lub cev xim yuav tsis dhau, uas tuaj yeem txuag cov txheej txheem ntxuav thaum hloov pwm hauv lub tshuab txhaj tshuaj.

Organic fluorescent hmoov:

A. Cov xim fluorescent yog ci thiab tsis muaj lub zog npog, nrog lub teeb nkag mus rau ntau dua 90%. Zoo solubility, txhua yam oily cov kuab tshuaj muaj peev xwm yaj, tab sis lub solubility yog txawv, yog li nws yuav tsum tau xaiv raws li cov kev xav tau sib txawv thaum siv.
B. Raws li cov dye series, xim yuav tsum tau them rau xim hloov teeb meem.
D. Vim huab cua tsis zoo, lwm yam stabilizers yuav tsum tau ntxiv thaum siv.
E Thaum tshav kub kub tsis kam: Qhov siab tshaj plaws tiv taus kub yog 200amp # 176C, haum rau kev ua haujlwm kub hauv 200amp # 176C

Daim ntawv thov cheeb tsam

1. tuaj yeem siv rau kev kos duab hauv cov chaw lom zem, kos duab hauv qab UV teeb pom kev zoo. 2. Tsim cov tshuaj tiv thaiv cuav, tshuaj tiv thaiv cuav, thiab cov tshuaj tiv thaiv cuav
3. Ua cov khoom kuaj zoo
4. Ntev yoj fluorescence anti-counterfeiting thev naus laus zis yog cov cuab yeej tiv thaiv kev ua lag luam siab tshaj tam sim no siv rau hauv cov nqi thiab cov txiaj ntsig, nrog kev zais zoo thiab cov cuab yeej txheeb xyuas cov npe nrov (cov khoom siv nyiaj feem ntau siv hauv khw muag khoom thiab tsev txhab nyiaj rau kev txheeb xyuas). Kev siv hluav taws xob luv luv los tiv thaiv kev ua txhaum cai siv cov cuab yeej tshwj xeeb rau kev txheeb xyuas, yog li muaj zog tiv thaiv kev ua txhaum cai thiab zais kev ua haujlwm. Fluorescent invisible ultraviolet excitation phosphor. Cov phosphor no nthuav tawm dazzling fluorescence nyob rau hauv ultraviolet irradiation thiab yog dav siv rau kev tiv thaiv cuav. Nws muaj cov yam ntxwv ntawm cov ntsiab lus thev naus laus zis siab thiab zoo xim zais.
