Sib txawv zog ntawm sulfur dub

Lub zog lossis concentration ntawm Sulfur Black dye yog ib qho tseem ceeb tshaj plaws hauv kev txiav txim siab qhov kawg ntawm dyeing paj rwb. Nws ncaj qha cuam tshuam tsis tsuas yog qhov tob ntawm qhov ntxoov ntxoo dub xwb tab sis kuj yog lub cev ntawm cov ntaub thiab kev ruaj ntseg ntawm cov txheej txheem dyeing. Nrhiav qhov sib npaug yog qhov tseem ceeb rau kev ua tiav qhov sib sib zog nqus dub thaum tswj kom zoo.

Qhov cuam tshuam tam sim ntawd ntawm kev ua kom muaj zog dye yog nyob ntawm qhov tob ntawm cov xim, feem ntau ntsuas raws li tus nqi K / S. Qhov ntau dua ntawm cov dyeing nyob rau hauv da dej ua rau ib tug tob thiab ntau saturated dub ntawm cov fiber. Piv txwv li, kev tshawb fawb optimizing Sulfur Black BR ​​tau qhia tias nyob rau hauv ib tug ntau dua concentration, xws li 60 grams ib liter nrog rau qhov tseeb txo tus neeg sawv cev, tus nqi K/S ntawm paj rwb xov paj tuaj yeem ncav cuag siab txog 46.88, qhia tias lub dav hlau puv thiab khaus heev -dub ntxoov ntxoo. Txawm li cas los xij, qhov kev sib raug zoo no tsis yog linear indefinitely, thiab tus nqi ntawm qhov tob nce slows down ntawm high concentrations.

Qhov cuam tshuam ntawm cov xim ceev ceev yog qhov nyuaj, tshwj xeeb tshaj yog hais txog kev nrawm nrawm. Thaum lub sij hawm ntxuav ceev thiab lub teeb nrawm ntawm Sulfur Black feem ntau yog qhov zoo ntawm cov qauv, xws li 6% qhov tob ntawm qhov ntxoov ntxoo, nws cov ntub dej ntub nrawm yog qhov paub tsis muaj zog. Thaum cov dye concentration yog siab dhau lawm, ntau tshaj ntawm cov khoom dye tseem tso rau ntawm qhov chaw fiber ntau es tsis yog tag nrho absorbed thiab bonded. Qhov zas xim saum npoo no tau yooj yim rub tawm, tshwj xeeb tshaj yog thaum cov ntaub ntub dej, ua rau tsis zoo ntub ntub nrawm. Ntawm tus txheej txheem 6% qhov tob, ntub dej nrawm yog feem ntau ntsuas qis, nyob ib ncig ntawm 1 txog 2, thiab txawm tias nrog cov txheej txheem optimization, nws yog ib qho nyuaj rau nce nws loj. Qhuav ceev ceev tsis tshua muaj kev cuam tshuam loj heev tab sis kuj tuaj yeem txo qis ntawm ntau qhov ntau.

Ib qho kev pheej hmoo tseem ceeb cuam tshuam nrog kev muaj siab ntawm Sulfur Black yog fiber ntau tendering, los yog poob ntawm lub zog ntawm cov ntaub. Sulfur Black muaj polysulfide bonds. Yog tias cov xim dye concentration siab dhau lawm, nws nyuaj rau ntxuav tawm tag nrho cov seem sulfur los ntawm fiber ntau. Nyob rau hauv cov huab cua sov thiab noo noo, cov residues tuaj yeem oxidize los ua sulfuric acid, uas degrades cov cellulose polymer chains, ua rau cov paj rwb ua nkig thiab tsis muaj zog. Yog li ntawd, ntau dua dye concentrations xav tau kev ntxuav ntau dua thiab ua haujlwm zoo dua los tiv thaiv - kev sib tw tom qab - kev kho mob kom tsis txhob muaj cov acidic residues thiab tiv thaiv cov ntaub ntev - lub sij hawm durability.

Los ntawm kev lag luam thiab cov txheej txheem kev pom, kev siv cov xim ntau dhau yog qhov tsis muaj txiaj ntsig thiab teeb meem. Cov dye exhaustion tus nqi tsis yog ib puas feem pua, yog li ib feem tseem ceeb ntawm cov dye ntau dhau mus rau hauv cov dej khib nyiab. Qhov no tsis yog tsuas yog khib nyiab kim heev tab sis kuj ua rau cov khoom siv tshuaj lom neeg ntau ntxiv, xws li Chemical Oxygen Demand, hauv cov dej phwj tuaj, ua rau kev kho mob nyuaj thiab kim. Tsis tas li ntawd, cov concentrations siab heev tuaj yeem ua rau muaj kev pheej hmoo ntawm dyeing unlevel dyeing thiab bronzy tsos ntawm cov ntaub.

Niaj hnub nimno siab -lub zog ua kua Sulfur Black formulations muaj qee qhov zoo hauv qhov no. Vim tias lawv zoo ib yam thiab muaj qhov nqus tau zoo dua piv rau cov ntaub ntawv hmoov, feem ntau lawv tuaj yeem ua tiav qhov xav tau sib sib zog nqus dub nrog tsawg dua cov tshuaj lom neeg thiab cov khoom ua kom zoo dua qub, thaum tseem ua rau muaj kev pheej hmoo tsawg dua rau kev nrawm nrawm.

Hauv kev xaus, kev ua kom lub zog ntawm Sulfur Black yog qhov cuab yeej tseem ceeb rau kev ua tiav cov xim dub, tab sis nws yuav tsum tau ua tib zoo tswj. Qhov zoo tshaj plaws concentration yog ib txwm muaj kev sib haum xeeb ntawm qhov xav pom qhov tob, qhov pom zoo ntawm cov ntaub ntub dej nrawm nrawm, thiab qhov tsim nyog ntawm kev khaws cov fiber ntau lub zog los ntawm kev ntxuav kom zoo thiab tiv thaiv - kev sib tw.
