Za Sulfur Blue 7

Nambala ya CAS:1327-57-7

Katundu: bluish-wofiirira ufa.Insoluble m'madzi, sungunuka mu sodium sulfide solution ndi greenish-gray.Ndi mtundu wa bluish-purple mu concentrated sulfuric acid ndipo umachepetsedwa kukhala buluu wakuda.Utoto umakhala wowala wachikasu wowala wa azitona mu njira ya ufa wa inshuwaransi yamchere, ndipo mtundu woyambirira ukhoza kubwezeretsedwanso pambuyo pa okosijeni;Kwathunthu chinazimiririka mu sodium hypochlorite njira;Amasanduka wofiirira wakuda pa sulfuric acid

Njira yopanga: nitrosation wa phenol sodium nitrite ndi sulfuric acid kupanga p-nitrosyphenol, condensation ndi o-toluidine kusungunuka mu sulfuric acid, kuchepetsa ndi vulcanization ndi sodium polysulfide ndi nambala inayake sulfure kunyezimira, ndiyeno kupyolera mpweya makutidwe ndi okosijeni, ndipo potsiriza kupyolera kusefera. , kuyanika, kuphwanya ndi mankhwala ovomerezeka kuti apange mankhwala.Zopangira zopangira (kg / t) O-toluidine (99%) 165-210 phenol (za mafakitale) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 koloko phulusa (makampani) 920-1120 sulfuric acid ( 100%) 900-1160 sulfure (99%) 430 sodium sulfide (63.5%) 480-620 Yuan ufa 10

Ntchito: Ndi yoyenera kupaka thonje, hemp, viscose ndi nsalu zake, komanso ingagwiritsidwe ntchito popaka vinylon.Izi zimapakidwa utoto wamtundu wa navy buluu, mtundu wake ndi wowala kwambiri.Dyeing ndondomeko bata ndi osauka, zosavuta oxidize zana wofiira m'mphepete, yopingasa, wofiira banga ndi zolakwika zina, makamaka Sulfur blue BRN, Sulfur blue 7 n'zosavuta kudziwa.Kugwiritsa ntchito utoto wa pad kungachepetse m'mphepete mwake, erythema ndi zolakwika zina.Chifukwa chiwerengero cha magulu a sodium polysulfide omwe amagwiritsidwa ntchito popanga mankhwalawa ndi osiyana, utoto wamalonda uli ndi mitundu yosiyanasiyana.Kuwala kwa buluu kumatchedwa Sulfur blue 7, kuwala kofiira kwa buluu kumatchedwaSulfur Blue 7, ndipo kuwala kofiira kumatchedwa Sulfur blue 7, yomwe iyenera kutsatiridwa pamene ikugwiritsidwa ntchito.Sulfur blue 7 ikhoza kupangidwa pogwiritsa ntchito o-nitroethylbenzene, mankhwala opangidwa popanga chloramphenicol, m'malo mwa o-toluidine.

Kampani yathu imapanga makamakaSulfure wakuda, Sulfur Black Madzi, Sulfur Blue 7.Kutumiza kosatha ku Bangladesh.India.Pakistan.Egypt, ndi Iran.Zonse zoperekedwa ndi khalidwe ndizokhazikika kwambiri.Chofunika kwambiri ndi phindu la mtengo
