Taw qhia
Pigment yellow 14, tseem hu ua barium dichromate daj, yog cov xim daj daj. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm Yellow 14:
Zoo:
- Cov tsos mob: daj 14 yog daj hmoov.
- Cov qauv tshuaj: Nws yog cov xim tsis muaj zog nrog cov qauv tshuaj ntawm BaCrO4.
- Durability: Yellow 14 muaj qhov ua tau zoo thiab tsis yooj yim cuam tshuam los ntawm lub teeb, kub thiab tshuaj lom neeg.
- Spectral zog: Yellow 14 muaj peev xwm nqus tau ultraviolet thiab xiav-violet lub teeb, xav txog lub teeb daj.
Siv:
- Yellow 14 yog dav siv nyob rau hauv coatings, xim, yas, roj hmab, ceramics thiab lwm yam lag luam los muab cov xim daj.
- Nws kuj yog feem ntau siv hauv kev kos duab thiab kos duab ua xim pab.
Txoj kev:
- Kev npaj ntawm daj 14 feem ntau yog tau los ntawm reacting barium dichromate nrog rau cov ntsev barium sib raug. Cov kauj ruam tshwj xeeb suav nrog kev sib xyaw ob, ua kom sov rau qhov kub thiab txias rau ib lub sijhawm, tom qab ntawd txias thiab lim lawv kom tsim cov xim daj daj, thiab thaum kawg ziab.
Cov ntaub ntawv kev nyab xeeb:
- Yellow 14 yog cov xim muaj kev nyab xeeb, tab sis tseem muaj qee qhov kev tiv thaiv kev nyab xeeb kom paub txog:
- Tsis txhob nqus los yog nkag mus rau hauv cov hmoov daj 14 kom tsis txhob ua xua ntawm lub ntsws thiab daim tawv nqaij.
