Siv
- UVINUL 5050 H feem ntau yog siv los ua lub teeb stabilizer rau cov khoom siv polymers thiab txheej txheej.
- Nws tuaj yeem nqus tau cov kab hluav taws xob ultraviolet zoo thiab txo qis qhov degradation ntawm cov ntaub ntawv polymer nyob rau hauv tshav ntuj thiab lwm yam ultraviolet rays.
- Nws tuaj yeem siv dav hauv cov ntaub ntawv uas xav tau huab cua tiv thaiv, xws li rooj tog sab nraum zoov, tsheb sab hauv, thiab vaj tsev.
Kev tshuaj xyuas
Cov tsos mob thiab cov khoom tshuaj xyuas: Nws yuav tsum yog lub teeb daj.
Melting point kev txiav txim: Nws yog txiav txim los ntawm ib tug melting point ntsuas, thiab nws melting point ntawm 95.00-125.00 degree.
Purity detection: Koj tuaj yeem xaiv siab -kev ua haujlwm ua kua chromatography lossis roj chromatography, yaj cov qauv nrog cov kuab tshuaj sib xws, sib piv nrog tus qauv, thiab txiav txim siab qhov purity.
Kev txheeb xyuas cov ntsiab lus dej: Siv Karl Fischer txoj kev, yaj cov qauv hauv cov kuab tshuaj tshwj xeeb, ntxiv cov reagent, thiab suav cov dej ntsiab lus raws li cov ntim ntim.
Kev kuaj pom kev ruaj ntseg: Los ntawm kev ntsuas thermal stability, cov qauv muab tso rau ntawm qhov sib txawv ntawm qhov kub thiab txias los soj ntsuam cov kev hloov pauv hauv qhov tsos, thiab lwm yam; lub teeb stability test exposes tus qauv rau lub teeb los xyuas cov kev hloov ntawm cov xim, thiab lwm yam.
