Cov Kab Mob Siv Tshuaj

Ultraviolet absorber yog ib hom teeb txawb, tuaj yeem nqus lub teeb pom kev zoo thiab qhov chaw ua kom zoo nkauj hauv ultraviolet ib feem, tab sis nws tus kheej tsis hloov.
Vim tias lub hnub ci ntsa iab muaj cov teeb meem loj ntawm ultraviolet teeb ua teeb meem los ntawm cov tshuaj lom neeg liab, cov xim molecules thaum kawg li decompose thiab ploj mus.
Muaj ob txoj hauv kev rau lub cev thiab tshuaj lom neeg los tiv thaiv cov xim puas tsuaj los ntawm cov teeb meem UV teeb meem.
Ntawm no yog qhia luv luv rau cov qauv tshuaj, uas yog, kev nqus UV los tiv thaiv cov khoom tiv thaiv zoo, lossis kom tsis muaj zog ntawm cov xim kev puas tsuaj.
UV nqus yuav tsum muaj cov xwm txheej hauv qab no
(1) muaj peev xwm nqus cov teeb civ ultraviolet (tshwj xeeb tshaj yog nthwv dej ntawm 290-400nm); (2) Zoo thermal stability, txawm nyob hauv kev ua yuav tsis hloov vim kub, qhov hluav taws kub me; Tshuaj lom neeg zoo, tsis muaj kev phiv nrog nrog cov khoom siv hauv cov khoom; (4) Kev ua txhaum txoj kev ua tsis zoo, tuaj yeem yog covyees dispersed nyob rau hauv cov khoom, tsis muaj te, tsis muaj exudation; (5) Cov duab thaij duab ruaj khov ntawm nqus nws tus kheej yog qhov zoo, tsis decompose, tsis hloov xim; ⑥ Tsis muaj xim, tsis muaj tshuaj lom, tsw ntxhiab; ⑦ Kuj yuav ua tau huv; ⑧ Pheej Yig Thiab Tau yooj yim Kom Tau; 9. Insoluble lossis insoluble hauv dej.
UV nqus tau tuaj yeem faib ua cov pab pawg hauv qab no raws li lawv cov tshuaj lom neeg tshuaj lom neeg, cov tshuaj pleev roj ntsha, hloov acrylonitrile, triazines thiab blocked amines.

Khoom Taw Qhia thiab Nta

Ultraviolet nqus tau yog qhov dav tshaj plaws ib qho ntawm lub teeb crylizer, raws li cov qauv siv tshuaj ntsuab, rau cov khoom siv ntawm bentry thiab lwm yam ntawm benzophenone thiab benzotriazole. Tus Quencher feem ntau yog hlau nyuaj, feem ntau yog cov txiaj ntsig ntawm lub teeb thiab cov khoom siv hluav taws xob hauv lub teeb, thiab nws tus kheej tsis hloov.
Vim tias lub hnub ci ntsa iab muaj cov teeb meem loj ntawm ultraviolet teeb ua teeb meem los ntawm cov tshuaj lom neeg liab, cov xim molecules thaum kawg li decompose thiab ploj mus.
Muaj ob txoj hauv kev rau lub cev thiab tshuaj lom neeg los tiv thaiv cov xim puas tsuaj los ntawm cov teeb meem UV teeb meem.
Nov yog qhia luv luv rau cov qauv tshuaj, uas yog, kev siv UV

kev siv

Nws tuaj yeem nqus cov teeb ci ntsa iab nrog lub nthwv dej 270-380 NM, tsuas yog siv rau cov khoom siv polyvinylene, polymy cob, thiab lwm yam nws haum rau cov ntaub ntawv sau xws li cov xim yeeb yaj kiab, cov duab xim, ntawv xim, ntawv xim thiab polymer, thiab lwm yam. Rau kev nqus tau zoo, kev ua tau zoo tsim ultraviolet aborber

Pob Thiab Thauj

B. Cov khoom lag luam no tuaj yeem siv ,, 25kg, baerls.
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
