Sulfur Black: Tus Ua Haujlwm Ntawm Cov Dyes Dub

Sulfur Dub: Tus Ua Haujlwm ntawm Cov Dyes Dub

Sulfur Black yog cov tshuaj zawv plaub hau uas siv ntau tshaj plaws, suav txog 75-85% ntawm tag nrho cov tshuaj zawv plaub hau thoob ntiaj teb. Nws yog cov hmoov dub los yog cov flake dub uas tsis muaj dej txaus tab sis soluble hauv sodium sulfide tov, ua rau ntsuab - xim dub. Nws cov qauv tshuaj muaj cov disulfide thiab polysulfide bonds, muab nws cov yam ntxwv dyeing zog.

Daim ntawv thov

Sulfur Dub feem ntau yog siv rau dyeing paj rwb textiles, nrog rau linen, viscose, thiab blended fabrics. Nws kuj yog siv rau hauv tawv thiab ntawv dyeing. Paub txog nws tus nqi qis, zoo heev ntxuav ceev ceev, thiab zoo lub teeb ceev ceev, nws yog txaus siab rau kev tsim cov duab sib sib zog nqus dub ntxoov hauv kev lag luam.

Dyeing Txheej Txheem & Kev Sib Tw

Cov txheej txheem dyeing suav nrog txo qis, dyeing, oxidation, thiab tom qab- kho:

· Txo: Sulfur Black yog txo nrog sodium sulfide los ua dej -soluble leuco daim ntawv uas muaj affinity rau cellulose fibers.

· Oxidation: Tom qab dyeing, cov ntaub yog oxidized los kho cov insoluble dye, nthuav tawm cov xim dub kawg.

Txawm li cas los xij, qhov kev sib tw tseem ceeb yog kev sib tw fiber ntau (tsis muaj zog). Residual sulfur compounds nyob rau hauv cov ntaub dyed tuaj yeem oxidize lub sij hawm los tsim sulfuric acid, uas degrades cellulose fibers. Txhawm rau tiv thaiv qhov no, cov ntaub yuav tsum tau muab ntxuav kom huv thiab kho nrog cov tshuaj tiv thaiv - cov tshuaj tiv thaiv xws li urea lossis sodium acetate tom qab dyeing.

Environmental & Safety Kev txhawj xeeb

Tsob Ntoo Sulfur Black dyeing yuav tsum muaj ntau tshaj sodium sulfide, ua cov dej khib nyiab nrog cov ntsiab lus sulfur uas nyuaj rau kev kho thiab tuaj yeem tso cov pa roj hydrogen sulfide. Thaum cov xim nws tus kheej raug suav tias tsis yog - lom rau tib neeg, nws 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, cov kua (ua ntej- txo) Sulfur Black tau tsim. Daim ntawv no tsis muaj impurities, tshem tawm qhov xav tau ntawm sodium sulfide thaum lub sij hawm ua, txo cov dej khib nyiab, thiab txhim kho qhov nrawm nrawm ntawm kwv yees li 0.5 qib. Nws tau txais ntau dua nyob rau hauv Western industrial lub teb chaws thiab yog dav siv rau denim yarn, knitted fabric, thiab pob dyeing.
