Taw qhia
Pigment Liab 185 yog cov organic hluavtaws pigment, tseem hu ua ci liab xim G, thiab nws cov tshuaj npe yog diaminaphthalene sulfinate sodium ntsev. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb ntawm Pigment Red 185:
Zoo:
- Pigment Liab 185 yog cov hmoov liab nrog cov khoom dyeing zoo thiab cov xim ci.
- Nws muaj qhov zoo lightfastness, kub tsis kam thiab acid thiab alkali tsis kam, thiab tsis yooj yim rau ploj.
Siv:
- Pigment Liab 185 feem ntau yog siv hauv kev lag luam dyeing thiab hauv kev tsim cov inks.
- Nws tuaj yeem siv rau textile dyeing, pigment printing, xim ntawm cov xim thiab cov khoom yas.
Txoj kev:
- Txoj kev npaj ntawm cov xim liab 185 feem ntau yog los ntawm nitrification cov tshuaj tiv thaiv ntawm naphthol, uas txo nitronaphthalene rau diaminophanephthalene, thiab ces reacts nrog chloric acid kom tau sodium ntsev ntawm diaminaphthalene sulfinate.
Cov ntaub ntawv kev nyab xeeb:
- Tsis txhob nqus pa, noj, lossis tiv nrog daim tawv nqaij. Nyob rau hauv rooj plaub ntawm kev sib chwv, yaug tam sim ntawd nrog dej ntau thiab nrhiav kev kho mob.
- Hnav hnab looj tes, tsom iav, thiab daim npog qhov ncauj thaum siv.
- Tsis txhob sib cuag nrog cov kua qaub, alkalis thiab lwm yam tshuaj.
- Khaws rau hauv qhov chaw qhuav, qhov cua, kom deb ntawm cov hluav taws kub thiab cov khoom siv hluav taws xob.
