Sulfur Dub: CIsulfur Black 1 CAS.1326-82-5 Chaw tsim tshuaj paus

Sulfur Black (CI Sulfur Black 1) yog qhov tseem ceeb tshaj plaws thiab dav siv cov tshuaj zawv plaub hau, suav txog kwv yees li 75-85% ntawm cov tshuaj zawv plaub hau thoob ntiaj teb. Nws zoo nkaus li cov hmoov dub los yog flake khoom, insoluble nyob rau hauv dej tab sis soluble nyob rau hauv sodium sulfide tov, qhov uas nws ua ib tug greenish - xim dub.

Cov yam ntxwv tseem ceeb

· Tus nqi qis - cov xim dub uas pheej yig tshaj plaws muaj

· Zoo ceev ceev - zoo ntxuav ceev ceev thiab lub teeb ceev ceev

· Ntau lawm ntim - dominates dub dye lag luam rau cellulosic fibers

Dyeing txheej txheem

Cov txheej txheem dyeing muaj peb kauj ruam tseem ceeb:

1. Kev txo qis: Cov dye txo qis siv sodium sulfide los ua dej -soluble leuco form

2. Dyeing: Daim ntawv leuco yog absorbed los ntawm paj rwb los yog lwm yam cellulosic fibers

3. Oxidation: Cov ntaub dyed raug rau huab cua lossis oxidizing cov neeg ua haujlwm, rov ua kom cov xim tsis zoo thiab nthuav tawm cov xim dub kawg.

Kev Sib Tw Loj: Fiber Tendering

Qhov teeb meem tseem ceeb tshaj plaws ntawm Sulfur Black yog fiber ntau tendering (lub zog poob). Cov tshuaj sulfur residual nyob rau hauv cov ntaub dyed maj mam oxidize lub sij hawm los tsim sulfuric acid, uas degrades thiab tsis muaj zog cellulose fibers. Txhawm rau tiv thaiv qhov no, dyed fabrics yuav tsum yog:

· Ua kom huv si tom qab dyeing

· Kho nrog cov tshuaj tiv thaiv -tendering agents xws li urea lossis sodium acetate

Kev txhawj xeeb txog ib puag ncig thiab kev nyab xeeb

Tsob Ntoo Sulfur Black dyeing yuav tsum muaj ntau tshaj sodium sulfide, tsim cov dej khib nyiab nrog cov ntsiab lus sulfur siab uas nyuaj rau kev kho thiab tuaj yeem tso cov pa roj hydrogen sulfide. Thaum cov xim nws tus kheej raug suav hais tias tsis yog - lom rau tib neeg, nws cov khoom tsim thiab siv ua rau muaj kev txhawj xeeb txog ib puag ncig.

Kev Txhim Kho Niaj Hnub No: Kua Sulfur Dub

Txhawm rau daws cov teeb meem no, ua ntej- txo cov kua Sulfur Black tau raug tsim. Daim ntawv no:

· Tsis muaj impurities

· Tshem tawm qhov xav tau ntxiv sodium sulfide thaum lub sijhawm ua haujlwm

· Txo cov dej khib nyiab ntau heev

· Txhim kho qhov nrawm nrawm ntawm kwv yees li 0.5 qib

Liquid Sulfur Black yog tam sim no dav siv rau denim yarn, knitted fabric, thiab pob dyeing nyob rau hauv ntau lub teb chaws muaj.

Daim ntawv thov

Sulfur Black feem ntau yog siv rau dyeing paj rwb textiles, nrog rau linen, viscose, thiab blended fabrics. Nws kuj yog siv rau hauv tawv thiab daim ntawv dyeing, qhov twg qhov sib sib zog nqus dub ntxoov yuav tsum tau ntawm tus nqi qis.
