Nhamba yeCAS:1327-57-7
Zvivakwa: bluish-yepepuru poda.Isinganyunguriki mumvura, soluble in sodium sulfide solution is greenish-gray.Iyo ine bluish-yepepuru muconcentrated sulfuric acid uye inonatswa kune yakasviba yebhuruu precipitate.Iyo dhayi inova yakareruka yero mwenje yemuorivhi ruvara mune alkaline inishuwarenzi poda mhinduro, uye iyo yepakutanga ruvara inogona kudzoserwa mushure meoxidation;Yakapera zvachose mu sodium hypochlorite solution;Inoshanduka yepepuru yakasviba pane concentrated sulfuric acid
Nzira yekugadzira: nitrosation ye phenol sodium nitrite uye sulfuric acid kugadzira p-nitrosyphenol, condensation ne o-toluidine yakanyungudutswa mu sulfuric acid, kuderedza uye vulcanization ne sodium polysulfide ine imwe sarufa inoratidza nhamba, uyezve kuburikidza negasi oxidation, uye pakupedzisira kuburikidza nekusefa. , kuomesa, kupwanya uye kurapa kwakagadziriswa kugadzira zvigadzirwa.Raw material kushandiswa (kg/t) O-toluidine (99%) 165-210 phenol (industrial) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 soda ash (industrial) 920-1120 sulfuric acid ( 100%) 900-1160 sarufa (99%) 430 sodium sulfide (63.5%) 480-620 Yuan powder 10
Zvishandiso: Yakakodzera kudhaya donje, hemp, viscose nemachira ayo, uye inogona zvakare kushandiswa kudhaya vinylon.Ichi chigadzirwa chakadhayiwa navy bhuruu main color dhayi, ruvara rwakanyanya kupenya.Dyeing process kugadzikana kwakashata, nyore kuoxidize zana dzvuku mupendero, yakachinjika, dzvuku gwapa uye kumwe kukanganisa, kunyanya Sulfur yebhuruu BRN, Sulfur yebhuruu 7 iri nyore kubata.Kushandiswa kwepedhi dyeing kunogona kuderedza mutsvuku mutsvuku, erythema uye zvimwe zvikanganiso.Nekuti huwandu hwemabheti e sodium polysulfide inoshandiswa mukugadzirwa kwechigadzirwa ichi yakasiyana, dhayi dzekutengesa dzine mavara akasiyana.Chiedza chebhuruu chinonzi Sulfur bhuruu 7, mwenje mutsvuku webhuruu unonziSulfur Blue 7, uye chiedza chitsvuku chinonzi Sulfur blue 7, iyo inofanira kubhadharwa kana yashandiswa.Sulfur yebhuruu 7 inogona kugadzirwa nekushandisa o-nitroethylbenzene, ne-chigadzirwa mukugadzirwa kwe chloramphenicol, panzvimbo ye o-toluidine.
Kambani yedu inonyanya kugadziraSulfur dema, Sulfur Black Liquid, Sulfur Blue 7.Perennial export to Bangladesh.India.Pakisitani.Egypt, uye Iran.Zvose zvinopiwa uye hutano zvakanyanya kugadzikana.Kunyanya kukosha ndeye mutengo mukana
