Sulfur Dub Hoobkas Muag

Sulfur Black yog ib qho ntawm feem ntau siv dyes hauv kev lag luam textile, feem ntau rau dyeing cellulose fibers. Ntawm no yog ib qho kev qhia txog kev paub txog cov khoom lag luam, suav nrog cov ntsiab lus yooj yim, hom loj, cov yam ntxwv tseem ceeb, thiab cov ntsiab lus tseem ceeb.

1. Cov ntsiab lus tseem ceeb thiab cov khoom siv tshuaj

Sulfur Black (CI Sulfur Black 1, CAS: 1326-82-}5) yog ib hom tshuaj molecular uas feem ntau muaj cov sulfur. Nws cov tsos yog feem ntau dub flaky solids los yog hmoov. Nws yog insoluble nyob rau hauv dej thiab cawv tab sis soluble nyob rau hauv cov kev daws ntawm sodium sulfide, tsim ib tug dub-ntsuab leuco compound. Nws yog tsim los ntawm hydrolyzing 2,4-dinitrochlorobenzene thiab tom qab ntawd muab nws rau cov tshuaj tiv thaiv sulfuration nrog sodium polysulfide.

2. Yam khoom tseem ceeb

Raws li daim ntawv thiab solubility, Sulfur Black feem ntau muab faib ua pawg hauv qab no:

Conventional Sulfur Black (xws li, BR 200%) Nws zoo nkaus li ci dub flakes lossis granules. Nws yog soluble hauv sodium sulfide tov. Hom tshuaj no yuav tsum tau txo nrog sodium sulfide rau dyeing thiab siv rau xim paj rwb, linen, thiab viscose.

Dej-Soluble Sulfur Black (S-BR) Nws zoo nkaus li zoo li dub granules lossis hmoov. Nws yog yooj yim soluble nyob rau hauv dej. Nws muaj kev yooj yim vim nws yuav tsum tsis muaj tus neeg sawv cev txo qis thiab tsim nyog rau tawv dyeing.

Liquid Sulfur Black Nws zoo nkaus li cov kua dub. Nws yog npaj siv. Hom no yog ib puag ncig tus phooj ywg, muaj tsawg dua impurities, muaj kev nqus siab, thiab tshem tawm qhov xav tau rau cov khoom siv zas xim nrog sodium sulfide.

3. Cov yam ntxwv tseem ceeb thiab kev ceev faj

Tendering Effect (Fiber Damage): Pa Sulfur Black muaj cov tsis ruaj khov polysulfide bonds hauv nws cov qauv molecular. Nyob rau hauv ib qho chaw ntub thiab kub, nws yooj yim oxidizes tsim sulfuric acid, uas tuaj yeem ua rau cov cellulose fibers ua nkig thiab tsis muaj zog. Yog li ntawd, kev ntxuav huv huv tom qab dyeing thiab tiv thaiv kev sib tw (siv cov tshuaj xws li urea lossis sodium acetate) yog qhov tsim nyog, lossis ib tus tuaj yeem xaiv ncaj qha los tiv thaiv - kev sib tw Sulfur Black.

Xim Shade Variations: Nyob ntawm cov txheej txheem tsim khoom (xws li sulfuration kub thiab sodium polysulfide piv), Sulfur Black tuaj yeem pom cov xim sib txawv, suav nrog xiav ntxoov ntxoo (BN), blueish - ntxoov ntxoo liab (BRN), thiab xim liab (RN).

Xim Fastness: Sulfur Black feem ntau qhia tau hais tias lub teeb nrawm nrawm (mus txog qib 5-6) thiab ntxuav ceev ceev ntawm cov ntaub paj rwb. Txawm li cas los xij, nws qhov ntub dej nrawm nrawm yog qhov qis (feem ntau yog qib 1-2).

4. Cov Ntsiab Lus Zoo

Raws li kev lag luam tus qauv HG/T3427-2001, cov ntsiab lus tseem ceeb rau qib qib Sulfur Black (xws li, BR 200%) yog raws li hauv qab no.

Cov tsos mob yuav tsum yog ci dub flakes los yog granules. Lub zog yog 100% ntawm tus qauv qauv, nrog cov lus qhia tshwj xeeb xws li 200% lossis 240% qhia txog lub zog sib txheeb. Cov dej noo yuav tsum tsawg dua lossis sib npaug li 6%. Insolubles hauv sodium sulfide tov yuav tsum tsawg dua los yog sib npaug ntawm 0.3% mus rau 0.5%. Cov ntsiab lus sulfur dawb yuav tsum tsawg dua lossis sib npaug li 0.5%.

5. Daim ntawv thov teb

Textile Dyeing: Nws yog tsuas yog siv rau dyeing paj rwb, linen, viscose, thiab vinylon / paj rwb blends. Nws yog tshwj xeeb tshaj yog haum rau dyeing sib sib zog nqus ntxoov xws li dub thiab xiav.

Lwm Cov Kev Siv: Dej-soluble Sulfur Black kuj tseem siv tau rau cov tawv dyeing thiab xim ntawv.
