NezveSulfur Blue 7

Nhamba yeCAS:1327-57-7

Hunhu: upfu hwebhuruu-pepuru. Husinganyungudike mumvura, hunonyungudika mu sodium sulfide solution, hwakaita segirini-grey. Hunonyungudika-pepuru mu sulfuric acid yakasanganiswa uye hunonyungudika kuita bhuruu rakasviba. Dhayi inova ruvara rweyero rwechiedza rwemuorivhi mu alkaline insurance powder solution, uye ruvara rwepakutanga runogona kudzoreredzwa mushure mekuoxidation; Hunonyangarika zvachose mu sodium hypochlorite solution; Hunoshanduka kuva dema repepuru pa sulfuric acid yakasanganiswa

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 nhamba yakati ye sulfur reflection, uyezve kuburikidza ne gas oxidation, uye pakupedzisira kuburikidza nekusefa, kuomesa, kupwanya uye kugadzirisa kwakajairika kugadzira zvigadzirwa. Kushandiswa kwezvinhu zvisina kucheneswa (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

Mashandisirwo: Yakakodzera kudhaya donje, hemp, viscose nemachira ayo, uye inogona kushandiswawo kudhaya vinylon. Chigadzirwa ichi chakadhayiwa neruvara rwebhuruu, ruvara rwacho rwakajeka. Kugadzikana kwemaitiro ekudhaya kwakashata, zviri nyore kuoxidanisa mupendero mutsvuku zana, wakatambanuka, nzvimbo tsvuku nezvimwe zvikanganiso, kunyanya Sulphur blue BRN, Sulphur blue 7 iri nyore kuibata. Kushandiswa kwepad dyeing kunogona kuderedza mupendero mutsvuku, erythema nezvimwe zvikanganiso. Nekuti huwandu hwemabhechi e sodium polysulfide anoshandiswa mukugadzira chigadzirwa ichi hwakasiyana, madhayi ekutengeserana ane mavara akasiyana. Mwenje webhuruu unonzi Sulphur blue 7, mwenje mutsvuku webhuruu unonziBhuruu reSulfur 7, uye mwenje mutsvuku unonzi Sulphur blue 7, unofanirwa kutariswa kana ukashandiswa. Sulphur blue 7 inogona kugadzirwa nekushandisa o-nitroethylbenzene, chinhu chinobva mukugadzirwa kwechloramphenicol, panzvimbo peo-toluidine.

Kambani yedu inonyanya kugadziraNhema yesarufa, Mvura Nhema yeSulfur, Bhuruu reSulfur 7.Kutengeswa kwezvinhu kuBangladesh kwenguva refu. India. Pakistan. Egypt, neIran. Kuwanikwa kwezvinhu uye mhando yazvo zvakagadzikana zvikuru. Chinonyanya kukosha inyaya yemutengo.
