Sulfur Dub: Tus Neeg Ua Haujlwm Ntawm Kev Lag Luam Dye Thiab Nws Pom Zoo Ntawm Tuam Tshoj INTERDYE 2026

Taw qhia: Huab tais ntawm Sulfur Dyes

Hauv kev lag luam dyeing thoob ntiaj teb, tsis muaj lwm cov xim sib xyaw ua ke muaj peev xwm, qhov tob ntawm qhov ntxoov ntxoo, thiab ntim ntau lawm zoo li Sulfur Black. Raws li feem ntau tsim thiab siv sulfur dye nyob rau hauv lub ntiaj teb no, nws muaj kwv yees li ntawm 75% mus rau 85% ntawm tag nrho cov sulfur dye ntau lawm. Paub hais tias yog Sulfur Black, Sulfur Yuan, los yog Sulfur Qing, cov xim no yog cov pob txha ntawm tsaus nti -cov xim cellulosic textiles, tshwj xeeb tshaj yog rau paj rwb, viscose, linen, thiab lawv cov khoom sib xyaw. Nws qhov tseem ceeb yog xws li tias nws tsim cov khoom lag luam tseem ceeb rau yuav luag txhua lub chaw tsim khoom loj dyeing ntawm CHINA INTERDYE 2026 hauv Shanghai.

Chemical Identity and Historical Context

Sulfur Black tsis yog ib qho tshuaj sib xyaw ua ke tab sis yog chav kawm ntawm cov heterocyclic polymers uas muaj cov tshuaj disulfide (S-S) thiab polysulfide bonds. Chemically, nws feem ntau yog tsim los ntawm cov tshuaj tiv thaiv ntawm 2,4-dinitrochlorobenzene los yog 2,4-dinitrophenol nrog sodium polysulfide (Na₂Sₓ), ua raws li huab cua oxidation.

Keeb kwm ntawm Sulfur Black hnub rov qab mus rau 1893, thaum R. Vidal thawj zaug ua ke cov xim dub los ntawm fusing p-aminophenol nrog sodium sulfide thiab sulfur . Qhov kev tawg no tau ua raws li kev tsim cov tshuaj zawv plaub hau hauv xyoo 1873. Tau ntau xyoo, Sulfur Black tseem tseem tsis tau muaj vim tias nws muaj qhov tshwj xeeb tus nqi: tus nqi qis heev, siab tinctorial zog, thiab zoo heev ntxuav ceev ceev. Tsis zoo li lwm cov xim dub uas yuav ua rau muaj kev txhawj xeeb txog kev mob carcinogenic, Sulfur Black tau pom dav tias tsis yog-carcinogenic, ua rau nws muaj kev nyab xeeb rau cov neeg ua haujlwm thiab kawg- cov neeg siv .

Cov khoom sib txawv thiab qib kev lag luam

Sulfur Black yog kev lag luam muaj nyob rau hauv ntau hom kom haum rau ntau hom kev thov thiab khoom siv. Ntawm CHINA INTERDYE 2026, cov neeg tuaj saib tuaj yeem cia siab tias yuav pom cov qauv hauv qab no ntawm cov khoom:

1. Powdered Sulfur Black (Conventional): Daim ntawv ib txwm muaj, nrog cov qauv dav dav ntawm D-S-S-D. Nws yog insoluble nyob rau hauv dej thiab yuav tsum tau dissolution nyob rau hauv ib tug sodium sulfide (Na₂S) tov los hloov nws mus rau hauv dej - soluble leuco daim ntawv ua ntej dyeing . Ib qho kev lag luam qib yog Sulfur Black BR ​​200% (Double Sulfur Black), uas yog cov khoom lag luam txheem nrog 100% lub zog txheeb ze rau tus qauv, zoo li ci dub flakes lossis granules. Cov qib tshwj xeeb no muaj qhov zoo tshaj plaws dyeing qhov tob, nrog rau 6% qhov tob (owf) ua tiav cov qauv xim dub.

2. Dej-Soluble Sulfur Black : Niaj hnub nimno versions nrog ib tug qauv ntawm D-SSO₃Na. Cov no yog sulfur-thiosulfates uas yaj ncaj qha hauv dej yam tsis tas yuav tsum tau ua ntej- txo, muab cov khoom zoo dua qub thiab tsis muaj plua plav.

3. Liquid Sulfur Black (Pre-txo): Formulated as D-SNa, cov kua no muaj ib tug txo tus neeg sawv cev (sodium sulfide) thiab npaj txhij siv ncaj qha rau hauv da dej zas xim. Lawv tshem tawm cov teeb meem plua plav cuam tshuam nrog cov hmoov thiab txhim kho batch-rau-batch sib xws .

4. Eco-Tus phooj ywg Sulfur Dub : Ib qho kev hloov tshiab tseem ceeb rau xyoo 2026 kev ua lag luam. Cov qib no muaj qis qis ntawm cov sulfur dawb thiab polysulfides. Lawv tau tsim los siv nrog binary txo cov tshuab (piv txwv li, qabzib thiab sodium hydrosulfite) es tsis txhob hnyav sodium sulfide, txo qis cov tshuaj sulfide cov ntsiab lus hauv cov dej khib nyiab.

Dyeing Mechanism: Ib Txoj Kev Redox

Sulfur Black ua raws li cov txheej txheem thov tshwj xeeb zoo ib yam li vat dyes, muaj plaub theem tseem ceeb:

1. Txo (Dissolution): Lub insoluble Sulfur Black yog kho nrog ib tug txo tus neeg sawv cev (ib txwm sodium sulfide) thiab alkali. Tus neeg sawv cev txo qis cleaves disulfide bonds, hloov cov dye rau hauv daim ntawv leuco (sodium ntsev ntawm thiol), uas yog dej -soluble thiab muaj affinity siab rau cellulose fibers.

2. Exhaustion (Adsorption): Cov leuco daim ntawv ntawm Sulfur Black yog absorbed los ntawm cov dye da dej mus rau hauv lub amorphous cheeb tsam ntawm cov paj rwb fiber. Lub affinity yog tsav los ntawm muaj zog van der Waals rog thiab hydrogen bonding, yooj yim los ntawm qhov loj molecular loj ntawm cov xim txo.

3. Oxidation (Fixation): Tom qab cov xim tau diffused rau hauv cov fiber ntau, nws yuav tsum tau re-oxidized. Daim ntawv leuco tau hloov rov qab mus rau hauv daim ntawv tsis sib xws, xim (re-ua S-S bonds). Qhov no feem ntau ua tiav tsuas yog los ntawm huab cua (cua oxidation) lossis siv cov tshuaj oxidizing me me. Cov kauj ruam no kaw cov zas xim hauv cov fiber ntau, kom ntseeg tau tias ntxuav ceev ceev.

4. Tshaj tawm -Kev Kho Mob : Ib kauj ruam kawg tseem ceeb. Cov tshuaj sulfur residual nyob rau hauv cov ntaub yuav maj mam oxidize nyob rau hauv cov huab cua los tsim sulfuric acid, uas hydrolyzes thiab tsis muaj zog (nkoos) paj rwb lub sij hawm. Tom qab- kev kho mob suav nrog kev ntxuav kom huv thiab siv cov tshuaj tiv thaiv- cov tshuaj tiv thaiv kab mob xws li urea, trisodium phosphate, lossis sodium acetate kom tsis txhob muaj cov kua qaub.

Cov yam ntxwv ua tau zoo thiab ceev ceev Properties

Sulfur Black yog xaiv rau kev ua haujlwm tshwj xeeb. Raws li cov ntaub ntawv qhia txog cov qib zoo li Sulfur Black BR ​​200%, cov khoom ceev ceev ntawm paj rwb yog qhov tseem ceeb:

· Lub Teeb Ceev (Xenon): 6 (ntawm qhov ntsuas ntawm 1-8, zoo heev).

· Ntxuav ceev (95 degree): 3-4 rau kev hloov xim, 4-5 rau staining (zoo rau zoo heev).

· Rubbing Fastness: Qhuav yog feem ntau 4-5 (zoo heev), tab sis ntub dej yog 2-3 (nruab nrab). Qhov no yog qhov paub txog kev txwv ntawm cov pa Sulfur Black vim qhov loj me me ntawm cov oxidized dye rau ntawm fiber ntau.

· Ua pa nrawm: 4-5 (zoo heev).

Txawm li cas los xij, kev lag luam paub txog nws qhov tsis muaj zog. Piv nrog rau cov dyes reactive dyes, Sulfur Black muaj duller ntxoov (feem ntau yog ib tug ntsuab -xiav los yog reddish-dub cam khwb cia) thiab qis ntub dej ceev ceev .

Environmental Challenges thiab Innovations ntawm CHINA INTERDYE 2026

Qhov kev sib tw thawj zaug ntsib ib txwm Sulfur Black yog nws ib puag ncig hneev taw. Cov pa dyeing yuav tsum tau siv ntau ntawm sodium sulfide (Na₂S). Tshaj sulfide hauv cov dej khib nyiab ua rau muaj kuab lom heev hydrogen sulfide (H₂S) gas, uas yog corrosive, malodorous, thiab muaj kev phom sij rau cov dej hauv dej thiab tib neeg kev noj qab haus huv. Kev kho cov sulfide no - nplua nuj effluent yog kim.

CHINA INTERDYE 2026 yog thawj qhov chaw uas cov kev daws teeb meem rau cov teeb meem no tau nthuav tawm. Raws li cov yeeb yam lub ntsiab lus ntawm "Green Development," cov neeg tuaj koom yuav tsom mus rau:

· Sulfide-dawb lossis qis-sulfide Sulfur Black : Cov khoom ua ntej-txo nrog kev nyab xeeb chemistry.

· Lwm Txoj Kev Txo Cov Txheej Txheem: Ua qauv qhia kev siv eco-cov neeg ua haujlwm txo qis zoo li qabzib ua ke nrog sodium hydrosulfite los hloov sodium sulfide nkaus, tso cai rau "Green Sulfur Black" dyeing .

· Advanced Post-Cov Tshuaj Kho Mob: Tshiab los tiv thaiv- cov tshuaj tiv thaiv brittleness thiab ntxuav- tawm cov pab cuam uas txo cov dej haus.

Sulfur Black ntawm Exhibition: Yuav Nrhiav Dab Tsi

Rau ib tus kws tshaj lij tuaj xyuas CHINA INTERDYE 2026, ntu Sulfur Black yuav tau tsom mus rau hauv Dyestuffs Hall .

Cov neeg tuaj saib yuav tsum nrhiav:

· High ntub-cov qib: Hloov Cov Sulfur Blacks uas ua tiav ntub dej nrawm ntawm 3 lossis siab dua.

· Eco- daim ntawv pov thawj daim ntawv pov thawj: Cov khoom ua raws li ZDHC (Zero Discharge of Hazardous Chemicals) thiab cov qauv bluesign.

· Digital integration: Liquid Sulfur Black formulations designs for automated dispensing systems in modern textile mills.

Xaus

Sulfur Black tseem yog cov khoom lag luam uas tsis tuaj yeem hloov pauv hauv cov khoom lag luam khoom lag luam. Nws cov nqi sib piv tsis sib xws-kev ua tau zoo thiab qhov sib sib zog nqus dub ntxoov ntxoo tsav lub ntiaj teb xav tau loj heev. Txawm li cas los xij, yav tom ntej ntawm Sulfur Black, raws li yuav pom tseeb ntawm CHINA INTERDYE 2026, nyob rau hauv ntsuab chemistry. Kev hloov pauv los ntawm kev txo qis sodium sulfide mus rau eco-tus phooj ywg, qis- sulfur, thiab cov ntaub ntawv ua kua tsis yog ib qho qauv xwb tab sis qhov tsim nyog tau tsav los ntawm kev tswj hwm thiab koom nrog cov hom phiaj kev ruaj ntseg. Rau txhua lub tshuab textile uas tsim cov xim tsaus, cov kev tsim kho tshiab hauv Sulfur Black tau nthuav tawm hauv Shanghai thaum Lub Plaub Hlis 2026 yuav yog tus yuam sij rau kev tswj hwm cov txiaj ntsig thiab kev ua raws li ib puag ncig.
