Fluorescent pigments muab txoj hauv kev zoo thiab muaj txiaj ntsig los txhim kho qhov pom kev pom thiab kev ua haujlwm ntawm koj cov khoom. Txawm li cas los xij, kev ua tiav qhov kev ua tau zoo yuav tsum tau ua tib zoo sim thiab ua kom zoo dua hauv koj cov txheej txheem tsim khoom tshwj xeeb. Raws li ib tugFluorescent Pigment Supplier, peb nkag siab qhov tseem ceeb ntawm cov txiaj ntsig zoo ib yam thiab txhim khu kev qha. Qhov blog no muab cov lus qhia ua tau zoo rau kev sim thiab ua kom zoo rau koj qhov kev ua tau zoo ntawm fluorescent Pigment, kom ntseeg tau qhov txiaj ntsig zoo tshaj plaws rau koj daim ntawv thov.

Kauj ruam-by-step qhia rau ntsuas Fluorescence siv thiab wavelength raug (nrog rau 980nm)

Kev ntsuas qhov fluorescence kom raug thiab qhov tseeb wavelength yog qhov tseem ceeb rau kev tswj kom zoo. Rau cov xim zoo li IR980nm, uas tawm hauv cov spectrum infrared, cov cuab yeej tshwj xeeb yog tsim nyog. Pib los ntawm kev npaj cov qauv tswj ntawm koj cov pigment dispersed nyob rau hauv lub npaj nruab nrab (resin, hnyav, thiab lwm yam). Siv lub spectrofluorometer kom zoo siab rau cov qauv nrog ib lub wavelength tshwj xeeb thiab ntsuas lub teeb tawm. Lub spectrofluorometer yuav muab cov ntaub ntawv ntawm qhov siv thiab lub wavelength ntawm emission fluorescence. Xyuas kom koj lub ntsuas ntsuas raug ntsuas kom raug thiab siv qhov chaw zoo sib xws rau txhua qhov ntsuas. Rau IR980nm, paub meej tias koj lub tshuab ntes tau rhiab hauv 980nm ntau yam. Sib piv koj cov kev ntsuas tawm tsam tus neeg muab khoom pigment qhov tshwj xeeb los txheeb xyuas cov xim ua haujlwm thiab txheeb xyuas qhov sib txawv. Kev ntsuas qhov sib npaug thiab raug yog qhov tseem ceeb rau kev txheeb xyuas qhov sib txawv ntawm batch-rau-batch thiab ua kom cov khoom sib xws.

Troubleshooting Common Issues: Dispersion Challenges in Water-Based vs. Solvent-Based Systems

Kev faib tawm kom raug yog qhov tseem ceeb rau kev ua tiav cov xim sib xws thiab pom cov fluorescence. Txawm li cas los xij, dispersion tuaj yeem nyuaj, tshwj xeeb tshaj yog thaum ua haujlwm nrog ntau lub hauv paus. Cov txheej txheem dej feem ntau xav tau kev siv cov surfactants lossis dispersants los tiv thaiv cov xim agglomeration. Cov kuab tshuaj raws li cov txheej txheem yuav ntsib cov teeb meem vim cov xim polarity txawv. Yog tias koj saib streaking, daws teeb meem, los yog txo cov fluorescence siv, nws yuav yog vim tsis zoo dispersion. Kev sim nrog cov dispersants sib txawv los yog kho cov txheej txheem sib xyaw kom txhim kho cov xim sib txawv. Xav txog cov xim ntawm qhov chaw kho mob - qee cov xim yog kho tshwj xeeb rau kev sib raug zoo nrog cov dej los yog cov kuab tshuaj raws li cov txheej txheem. Yog tias koj ntsib teeb meem cuam tshuam tsis tu ncua, sab laj nrog kojFluorescent Pigmenttus neeg muag khoom rau cov lus pom zoo.
