Hais txog Sulfur Blue 7

CAS nr:1327-57-7 ib

Khoom: xiav-ntsuab hmoov.Insoluble hauv dej, soluble hauv sodium sulfide tov yog greenish-grey.Nws yog xiav-ntsuab nyob rau hauv concentrated sulfuric acid thiab yog diluted mus rau ib tug tsaus xiav precipitate.Cov dye ua lub teeb daj lub teeb txiv ntseej xim hauv cov tshuaj tiv thaiv alkaline hmoov, thiab cov xim qub tuaj yeem rov qab los tom qab oxidation;Ua tiav faded nyob rau hauv sodium hypochlorite tov;Nws hloov ntshav tsaus rau ntawm cov concentrated sulfuric acid

Cov txheej txheem ntau lawm: nitrosation ntawm phenol sodium nitrite thiab sulfuric acid los tsim p-nitrosyphenol, condensation nrog o-toluidine yaj nyob rau hauv sulfuric acid, txo thiab vulcanization nrog sodium polysulfide nrog ib co sulfur reflection tooj, thiab ces los ntawm cov roj oxidation, thiab thaum kawg los ntawm pom. , ziab, crushing thiab standardized kev kho mob los tsim cov khoom.Cov khoom siv raw (kg / t) O-toluidine (99%) 165-210 phenol (industrial) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 soda tshauv (industrial) 920-1120 sulfuric acid ( 100%) 900-1160 sulfur (99%) 430 sodium sulfide (63.5%) 480-620 Yuan hmoov 10

Kev Siv: Nws yog tsim rau dyeing paj rwb, hemp, viscose thiab nws cov ntaub, thiab tuaj yeem siv rau dyeing vinylon.Cov khoom no yog dyed navy xiav lub ntsiab xim dye, xim yog ci dua.Dyeing txheej txheem stability tsis zoo, yooj yim rau oxidize ib puas liab ntug, kab rov tav, liab chaw thiab lwm yam tsis xws luag, tshwj xeeb tshaj yog sulfur xiav BRN, Sulfur xiav 7 yog yooj yim rau tswv.Kev siv pad dyeing tuaj yeem txo cov ntug liab, erythema thiab lwm yam tsis xws luag.Vim hais tias tus naj npawb ntawm cov khoom siv ntawm sodium polysulfide siv los tsim cov khoom no txawv, cov khoom lag luam dyes muaj xim sib txawv.Lub teeb xiav hu ua Sulfur xiav 7, lub teeb xiav xiav hu uaSulfur Blue 7, thiab lub teeb liab hu ua Sulfur xiav 7, uas yuav tsum tau them sai sai rau thaum thov.Sulfur xiav 7 tuaj yeem tsim los ntawm kev siv o-nitroethylbenzene, ib qho khoom los ntawm kev tsim cov tshuaj chloramphenicol, tsis yog o-toluidine.

Peb lub tuam txhab tsuas yog tsimSulfur dub, Sulfur Black Liquid, Sulfur Blue 7. Perennial export rau Bangladesh.Is Nrias teb.Pakistan.Egypt, thiab Iran.Ob qhov khoom thiab qhov zoo yog qhov ruaj khov.Qhov tseem ceeb tshaj yog tus nqi kom zoo dua
