Kev Siv Khoom Siv Ntawm Sulfur Black

Kev lag luam siv Sulfur Black yog qhov dav, feem ntau yog tsom rau hauv kev lag luam textile, tab sis nws kuj txuas mus rau thaj chaw xws li tawv thiab ntawv tsim.

Main Industrial Application Areas

1. Textile Industry (Core Application) Qhov no yog daim ntawv thov ntim loj tshaj plaws rau Sulfur Black, feem ntau yog siv rau dyeing cellulose fibers:

· Paj Rwb: Siv rau dyeing yarn, knitted fabric, thiab woven fabric (xws li corduroy thiab poplin). Nws yog ib qho tseem ceeb tshwj xeeb rau kev tsim denim, qhov twg Sulfur Black yog qhov thib ob tseem ceeb tshaj plaws dye tom qab indigo rau kev tsim cov ris tsho dub thiab cov ris tsho ua haujlwm.

· Linen: Siv rau hauv dyeing linen lossis ramie fabrics.

· Viscose: Siv rau dyeing rayon fabrics kom ua tau ib tug tob, dav hlau -dub ntxoov ntxoo.

· Vinylon: Ua hauj lwm hauv dyeing vinylon fibers, feem ntau ua ke nrog lwm cov dyes xws li Sulfur Black CLG kom ua tiav cov xim dub ntshiab.

2. Tawv Kev Lag Luam Dej-soluble Sulfur Black yog dav siv rau tawv dyeing, tshwj xeeb tshaj yog rau chrome- tanned tawv. Nws imparts ib tug uniform, sib sib zog nqus dub xim rau tawv thiab muab zoo lub teeb ceev ceev.

3. Kev Lag Luam Ntawv Siv hauv kev tsim cov ntawv tshwj xeeb xim, ntim ntawv, lossis cov ntawv ntawv. Sulfur Black muab cov xim dub muaj zog thiab kav ntev rau daim ntawv.

Cov yam ntxwv ntawm daim ntawv thov los ntawm Cov Khoom Siv

Cov ntaub ntawv sib txawv ntawm Sulfur Black yog haum rau ntau yam khoom siv thiab cov txheej txheem:

· Tsis tu ncua hmoov/Flake

· Cov yam ntxwv: Insoluble nyob rau hauv dej, yuav tsum tau dissolution nrog ib tug txo tus neeg sawv cev zoo li sodium sulfide.

· Daim ntawv thov: Tsim nyog rau cov tsoos pa dyeing thiab jig dyeing txheej txheem. Piv txwv li, dyeing paj rwb xov hauv dyeing da dej los yog dyeing paj rwb ntaub ntawm jiggers. Qhov no yog daim ntawv feem ntau tsoos thiab siv dav.

· Solubilized hmoov

· Cov yam ntxwv: Soluble hauv dej ncaj qha, siv tau yooj yim, thiab muaj kev nkag tau zoo.

· Daim ntawv thov: Zoo tagnrho rau cov ntaub qhwv tsis tu ncua-dyeing txheej txheem rau loj- nplai, siab- ua tau zoo dyeing ntawm paj rwb thiab viscose fabrics. Daim ntawv no kuj yog qhov kev xaiv zoo tshaj plaws rau tawv thiab ntawv dyeing.

· Liquid Sulfur Black (Pre-txo)

· Cov yam ntxwv: Muab raws li kev npaj ua ntej-rau- siv cov kua, ua ntej- txo qis, nrog purity siab, ob peb impurities, zoo stability, thiab tsawg tsawg.

· Daim ntawv thov: Sawv cev rau niaj hnub, eco- kev coj tus phooj ywg. Nws yog tshwj xeeb tshaj yog haum rau slasher dyeing ntawm denim warp yarns thiab kuj yog dav siv rau dyeing knitted fabrics thiab pob dyeing. Nws tsim cov dej khib nyiab tsawg dua thiab muab cov xim nrawm dua.

Cov Ntsiab Cai Tswj Cov Ntsiab Lus

Tsis hais txog ntawm daim ntawv, Sulfur Black dyeing ua raws cov txheej txheem ntawm Kev Txo → Absorption → Oxidation → Tom qab kho.

· Txo thiab nqus tau: Cov dye yog hloov mus rau hauv daim ntawv leuco (uas muaj affinity rau fiber ntau) los ntawm ib tug txo tus neeg sawv cev thiab yog absorbed los ntawm cellulose. Cov ntaub ntawv ua kua muaj kev tswj xyuas zoo dua ntawm cov txheej txheem no vim lawv qhov ruaj khov.

· Oxidation rau Color Development: Lub absorbed dye yog oxidized los ntawm huab cua los yog ib tug oxidizing neeg sawv cev, converting nws rov qab mus rau nws insoluble daim ntawv thiab xauv cov xim rau hauv fiber.

· Kev Tiv Thaiv Kev Tiv Thaiv: Cov sulfur hauv cov xim tuaj yeem oxidize thaum lub sij hawm cia, tsim sulfuric acid uas tuaj yeem ua rau cov fibers tsis muaj zog. Kev ntsuas kev lag luam yog qhov tseem ceeb:

· Thorough Washing: To remove residual sulfur and alkali from the fiber.

· Anti-Tendering Aftertreatment: Kho cov ntaub nrog anti-tendering agents xws li urea, sodium acetate, los yog trisodium phosphate.

· Siv Tsis yog-Kev sib tw hom: ncaj qha siv tshwj xeeb stabilized Non-tendering Sulfur Black dyes los daws qhov teeb meem.

· Kev txiav txim siab ib puag ncig: Cov txheej txheem ib txwm siv sodium sulfide ua kom muaj -sulfur wastewater. Yog li ntawd, cov ntawv thov kev lag luam tau nce zuj zus mus rau cov kua Sulfur Black thiab eco- tus phooj ywg txo cov neeg ua haujlwm zoo li qabzib kom txo tau cov khoom ib puag ncig.
