Qhov tsos ntawmdub sulfuryog cov siv lead ua xim dub, thiab qhov saum npoo ntawm cov siv lead muaj ntau qib sib txawv ntawm lub teeb (hloov pauv nrog qhov hloov pauv ntawm lub zog). Cov kua dej yog cov kua dub, thiab cov sulfur dub yuav tsum tau yaj los ntawm cov kua sodium sulfide.
Cov tshuaj siv lead ua dub pro Sulfur yog cov xim pleev xim uas yog los ntawm tsev neeg cov xim pleev xim sulfur. Nws feem ntau siv rau hauv kev lag luam textile rau kev zas xim paj rwb vim nws muab cov xim dub tob. Sulfide Black Crystal paub txog nws cov xim zoo heev, uas txhais tau tias nws yuav tsis ploj txawm tias tom qab ntxuav ntau zaus lossis raug tshav ntuj. Nws kuj tseem pheej yig thiab muaj ntau 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 mob kom tau txais 2,4-dinitrophenol sodium ntsev, uas yog tom qab ntawd ntxiv rau sodium polysulfide kua rau vulcanization. Tom qab oxidation, filtration, Cov khoom tiav lawm yog qhuav.
Cov xim dub sulfur feem ntau yog siv rau kev zas xim paj rwb, hemp, viscose thiab nws cov ntaub sib xyaw. Feem ntau ntawm cov ntaub denim (dub) nrov hauv tsev thiab txawv teb chaws yog ua los ntawm cov xov dub warp thiab cov xov dawb. Cov xim dub sulfur muaj ntau cov disulfide bonds tom qab raug txo los ntawm sodium sulfide, thiab nws yooj yim rau oxidized kom txo lub zog ntawm cov ntaub dyed, uas yog, brittleness. Yuav kom tiv thaiv kev puas tsuaj brittle, koj yuav tsum tau them sai sai rau cov ntsiab lus no:
1. Tswj kom tsis txhob muaj cov sulfur dub ntau dhau. Yog muaj sulfur dub ntau dhau, ces yuav ua rau cov khoom puas tsuaj ntau dua.
2, Ntxuav kom huv si kom txo cov xim ntab ntawm cov khoom thauj.
3, Siv cov tshuaj ntxiv rau Taikoo Oil kom tiv thaiv kev tawg.
4. Ua ntej zas xim, siv dej tshiab los ntxuav cov xov paj. Cov xov paj uas tau muab dej sim rau tom qab zas xim lawm yuav tawg yooj yim dua li lye.
5. Qhuav raws sijhawm tom qab zas xim kom txo cov ntsiab lus ntawm cov khoom siv tiv thaiv kev tawg vim yog kev sib sau ua ke ntawm cov dej noo.
