Taw qhia

Pigment Liab 149 yog cov organic pigment nrog cov tshuaj npe ntawm 2-(4-nitrophenyl) acetic acid-3-amino4,5-dihydroxyphenylhydrazine. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov xim:

Zoo:

- Pigment Liab 149 tshwm raws li cov hmoov liab liab.

- Nws muaj lub teeb pom kev zoo thiab huab cua tsis kam, thiab tsis yooj yim corroded los ntawm acids, alkalis thiab cov kuab tshuaj.

- Pigment Liab 149 muaj lub siab chromaticity, ci thiab ruaj khov xim.

Siv:

- Pigment Liab 149 feem ntau yog siv los ua cov xim liab hauv kev lag luam xws li xim, txheej, yas, roj hmab thiab textiles.

- Nws tuaj yeem siv los npaj cov pigments thiab inks, nrog rau hauv cov teb xws li dyes, inks, thiab xim offset printing.

Txoj kev:

- Kev npaj cov xim liab 149 feem ntau yog los ntawm cov tshuaj tiv thaiv ntawm aniline nrog nitrobenzene kom tau nitroso tebchaw, thiab tom qab ntawd cov tshuaj tiv thaiv ntawm o-phenylenediamine nrog nitroso tebchaw kom tau cov xim liab 149.

Cov ntaub ntawv kev nyab xeeb:

- Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, qhov ncauj qhov ntswg, thiab tsom iav thaum siv.

- Tsis txhob muab pov tseg ncaj qha rau hauv ib puag ncig thiab tuav thiab khaws cia kom zoo.

- Thaum siv Pigment Red 149, nws yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam rau kev ua haujlwm kom muaj kev nyab xeeb thiab kev noj qab haus huv.
