tshuaj ua kom ci ntsa iab
cov yam ntxwv tshuaj lom neeg
Raws li lawv cov qauv tshuaj lom neeg, lawv tuaj yeem muab faib ua tsib pawg:
1, hom stilbene: siv rau paj rwb fiber thiab qee cov khoom siv hluavtaws, ntawv ua, xab npum thiab lwm yam lag luam, nrog xiav fluorescence;
2, hom coumarin: nrog cov qauv coumarin yooj yim, siv rau celluloid, PVC yas, nrog lub zog xiav fluorescence;
3, hom pyrazoline: siv rau cov ntaub plaub, polyamide, acrylic fiber thiab lwm yam fibers, nrog xim ntsuab fluorescent;
4, benzoxy nitrogen hom: siv rau acrylic fibers thiab polyvinyl chloride, polystyrene thiab lwm yam yas, nrog rau liab fluorescence;
5, hom benzoimide siv rau polyester, acrylic, nylon thiab lwm yam fibers, nrog xiav fluorescence.
Kev taw qhia txog khoom thiab nta
Cov tshuaj ci ntsa iab fluorescent (fluorescent brightener) yog cov xim fluorescent, lossis cov xim dawb, uas kuj yog ib lo lus dav dav rau ib pawg ntawm cov tshuaj sib xyaw. Nws cov yam ntxwv yog tias nws tuaj yeem ua rau lub teeb ci ntsa iab los tsim cov fluorescence, yog li cov khoom siv uas muaj kuab paug muaj cov nyhuv zoo ib yam li cov fluorite glitter, yog li qhov muag liab qab tuaj yeem pom cov khoom siv dawb heev.
siv
Thawj qhov kev piav qhia txog kev siv fluorescence tau los txog rau xyoo 1852, thaum Stokes tau hais txog qhov uas tau los ua lub npe hu ua Stokes' Law. Xyoo 1921 Lagorio tau pom tias lub zog fluorescence pom uas cov xim fluorescent tso tawm qis dua lub zog pom uas lawv nqus tau. Vim li no, nws tau txiav txim siab tias cov xim fluorescent muaj peev xwm hloov lub teeb ultraviolet uas tsis pom mus rau hauv fluorescence pom. Nws kuj pom tias qhov dawb ntawm cov fibers ntuj tuaj yeem txhim kho los ntawm kev kho lawv nrog cov kua dej ntawm cov tshuaj fluorescent. Xyoo 1929, Krais siv Lagorio txoj cai los ua pov thawj tias cov xim daj rayon tau muab tso rau hauv cov kua ntawm 6, 7-dihydroxycoumarin glycosyl. Tom qab ziab, nws tau pom tias qhov dawb ntawm rayon tau txhim kho zoo heev.
Kev loj hlob sai ntawm cov tshuaj fluorescent brighteners tau ua rau qee tus neeg suav lawv nrog kev tshwm sim ntawm cov xim reactive thiab cov xim organic DPP ua peb qhov kev ua tiav loj hauv kev lag luam xim thaum xyoo pua 20th.
Muaj ntau lub lag luam tau pib siv cov tshuaj fluorescent brighteners, xws li ntawv, yas, tawv, thiab lwm yam. Tib lub sijhawm, hauv ntau lub teb high-tech kuj siv cov tshuaj fluorescent whitening agent, xws li: fluorescence detection, dye laser, anti-cuav printing, thiab lwm yam., thiab txawm tias cov duab thaij duab siab nrog cov zaj duab xis rhiab heev los txhim kho qhov rhiab heev ntawm cov duab latex, kuj tseem yuav siv cov tshuaj fluorescent whitening agent.
pob khoom thiab kev thauj mus los
B. Cov khoom no siv tau,,25KG, 200KG, 1000KGBAERRLS。
C. Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag hauv tsev. Yuav tsum kaw cov thawv kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum tau kaw zoo thaum lub sijhawm thauj mus los kom tiv thaiv cov dej noo, alkali thiab acid muaj zog, nag thiab lwm yam tsis huv los ntawm kev sib tov.
