Cov tsos ntawmsulfur dubyog dub flaky siv lead ua, thiab qhov saum npoo ntawm cov siv lead ua muaj qhov sib txawv ntawm lub teeb (hloov nrog kev hloov ntawm lub zog). Cov tshuaj aqueous yog cov kua dub, thiab cov sulfur dub yuav tsum tau yaj los ntawm cov tshuaj sodium sulfide.
Tus pro Sulfur dub siv lead ua yog cov xim hluavtaws uas muaj nyob hauv tsev neeg leej faj dye. Nws yog feem ntau siv hauv kev lag luam textile rau dyeing paj rwb fibers vim nws muab cov xim dub sib sib zog nqus. Sulfide Black Crystal paub txog nws cov xim zoo nkauj ceev ceev, uas txhais tau tias nws yuav tsis ploj txawm tias tom qab rov ntxuav dua lossis raug tshav ntuj. Nws kuj yog tus nqi-zoo thiab dav muaj nyob rau hauv kev ua lag luam.
Cov txheej txheem duction ntawm sulfur dub yog raws li 2,4-dinitrochlorobenzene, uas yog hydrolyzed nyob rau hauv alkaline tej yam kev mob kom tau 2,4-dinitrophenol sodium ntsev, uas yog ces ntxiv rau sodium polysulfide tov rau vulcanization. Tom qab oxidation, pom, cov khoom tiav yog qhuav.
Sulfur dub yog tsuas yog siv rau dyeing paj rwb, hemp, viscose thiab nws blended fabrics. Feem ntau ntawm cov denim fabrics (dub) nrov nyob rau hauv tsev thiab txawv teb chaws yog ua los ntawm woven dub warp yarn thiab dawb yarn. Sulfur dub muaj ntau yam disulfide bonds tom qab raug txo los ntawm sodium sulfide, thiab nws yog ib qho yooj yim rau oxidized kom txo tau lub zog ntawm dyed fabrics, uas yog, brittleness. Txhawm rau tiv thaiv kev puas tsuaj brittle, koj yuav tsum tau xyuam xim rau cov ntsiab lus no:
1 、 Tswj tus nqi ntawm sulfur dub. Qhov ntau npaum li cas ntawm cov sulfur dub, qhov yuav ua rau muaj kev puas tsuaj ntau dua.
2 、 Ntxuav kom huv si kom txo cov xim ntab ntawm cov khoom thauj.
3 、 Siv Taikoo Roj cov khoom ntxiv los tiv thaiv embrittlement.
4 、 Souring nrog dej tshiab ua ntej dyeing. Cov xov paj embrittlement nrog cov dej kuaj tom qab dyeing muaj qhov zoo ntawm embrittlement dua li lye.
5 、 Qhuav nyob rau lub sijhawm tom qab dyeing kom txo cov ntsiab lus ntawm cov khoom siv los tiv thaiv brittle los ntawm kev ntub dej.
