Mawu Oyamba
Pigment Red 185 ndi organic synthetic pigment, yomwe imadziwikanso kuti red red pigment G, ndipo dzina lake lamankhwala ndi diaminaphthalene sulfinate sodium mchere. Zotsatirazi ndikuwulula za katundu, ntchito, njira zopangira ndi chidziwitso cha chitetezo cha Pigment Red 185:
Ubwino:
- Pigment Red 185 ndi ufa wofiira wokhala ndi zida zabwino zodaya komanso mitundu yowala.
- Ili ndi kuwala kwabwino, kukana kutentha ndi asidi ndi alkali kukana, ndipo sikophweka kuzimiririka.
Gwiritsani ntchito:
- Pigment Red 185 imagwiritsidwa ntchito kwambiri popanga utoto komanso kupanga inki.
- Itha kugwiritsidwa ntchito popaka utoto, kusindikiza pigment, utoto wa utoto ndi zinthu zapulasitiki.
Njira:
- Kukonzekera njira ya pigment wofiira 185 makamaka kudzera nitrification anachita naphthol, amene amachepetsa nitronaphthalene kuti diaminophanephthalene, ndiyeno amachitira ndi chloric asidi kupeza sodium mchere wa diaminaphthalene sulfinate.
Zambiri Zachitetezo:
- Pewani kutulutsa mpweya, kumeza, kapena kukhudza khungu. Mukakhudzana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
- Valani magolovesi oteteza, magalasi, ndi chigoba mukamagwiritsa ntchito.
- Pewani kukhudzana ndi asidi amphamvu, alkalis ndi mankhwala ena.
- Sungani pamalo owuma, opanda mpweya, kutali ndi moto ndi zinthu zomwe zimatha kuyaka.
