Ibyerekeye Sulfur Blue 7

Nimero ya CAS:1327-57-7

Imiterere: ifu y'ubururu n'umuhengeri. Idashonga mu mazi, ishonga mu gisubizo cya sodium sulfide iba ifite ibara ry'icyatsi kibisi n'umukara. Iba ifite ibara ry'ubururu n'umuhengeri muri aside sulfurike yijimye kandi ikavangwa n'ubururu bwijimye. Ibara rihinduka ibara ry'umuhondo woroshye mu gisubizo cya alkaline, kandi ibara ry'umwimerere rishobora kugaruka nyuma yo gushonga; Irashira burundu mu gisubizo cya sodium hypochlorite; Ihinduka umuhengeri wijimye ku gisubizo cya sodium sulfurike yijimye

Uburyo bwo gukora: Gutera nitrosation ya phenol sodium nitrite na aside sulfurike kugira ngo hakorwe p-nitrosyphenol, gushonga hamwe na o-toluidine ishongeshejwe muri aside sulfurike, kugabanya no gukurura hamwe na sodium polysulfide hamwe n'umubare runaka wa sulfur reflection, hanyuma binyuze muri oxidation ya gaze, hanyuma binyuze mu kuyungurura, kumisha, gusya no gutunganya ibintu bisanzwe kugira ngo hakorwe ibicuruzwa. Ikoreshwa ry'ibikoresho fatizo (kg/t) O-toluidine (99%) 165-210 phenol (inganda) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 soda ivu (inganda) 920-1120 aside sulfurike (100%) 900-1160 sulfur (99%) 430 sodium sulfide (63.5%) 480-620 Yuan ifu 10

Ikoreshwa: Ikwiriye gusiga irangi ipamba, hemp, viscose n'imyenda yayo, kandi ishobora no gukoreshwa mu gusiga irangi vinylon. Iki gicuruzwa gikozwe mu irangi ry'ubururu butukura, ibara rirabagirana cyane. Uburyo bwo gusiga irangi ntibuhamye, byoroshye gusiga irangi ry'umutuku ijana, ritambitse, ahantu hatukura n'ibindi bidafite ubuziranenge, cyane cyane ubururu bwa Sulfur BRN, ubururu bwa Sulfur 7 biroroshye kubimenya. Gukoresha irangi rya pad bishobora kugabanya irangi ry'umutuku, erythema n'ibindi bidafite ubuziranenge. Kubera ko umubare w'amabara ya sodium polysulfide akoreshwa mu gukora iki gicuruzwa utandukanye, amarangi yo kugurisha afite amabara atandukanye. Itara ry'ubururu ryitwa Sulfur blue 7, itara ry'ubururu ryitwaUbururu bwa Sulfure 7, kandi itara ritukura ryitwa Sulfur blue 7, rigomba kwitabwaho iyo rikoreshejwe. Sulfur blue 7 ishobora gukorwa hakoreshejwe o-nitroethylbenzene, umusaruro ukomoka ku ikorwa rya chloramphenicol, aho gukoresha o-toluidine.

Isosiyete yacu ikora cyane cyaneUmukara wa sulfure, Amazi y'umukara ya Sulfure, Ubururu bwa Sulfure 7.Kohereza ibicuruzwa muri Bangladesh igihe cyose. Ubuhinde. Pakisitani. Misiri, na Irani. Itangwa ry'ibicuruzwa n'ubwiza bwabyo birahamye cyane. Icy'ingenzi kurushaho ni inyungu ku giciro
