Kua Sulfur Dub

Sulfur dub yog lub siab molecular compound nrog ntau cov sulfur.Nws cov qauv muaj cov disulfide bonds thiab polysulfide bonds, thiab nws tsis ruaj khov heev.Tshwj xeeb, polysulfide bonds tuaj yeem oxidized rau hauv sulfur oxides los ntawm cov pa oxygen hauv huab cua hauv qee qhov kub thiab av noo, thiab ntxiv cuam tshuam nrog cov dej molecules hauv huab cua los tsim sulfuric acid, kom cov xov paj txo qis, cov fiber ntau yog nkig, thiab nyob rau hauv loj heev, cov fiber yog kiag li nkig rau hauv hmoov.Yog li ntawd, txhawm rau txo lossis tiv thaiv fiber ntau embrittlement ntawm cov xov paj dyed nrog dub sulfide dye, cov ntsiab lus hauv qab no yuav tsum tau them rau:

 

1. Tus naj npawb ntawm sulfur dub dye yuav tsum raug txwv, thiab tus nqi ntawm mercerized tshwj xeeb xim dye yuav tsum tsis pub tshaj 700g / hnab.Vim tias qhov ntau npaum li cas ntawm cov dyes, muaj feem ntau ntawm brittleness, thiab cov xim ceev yuav txo, yog li nws nyuaj rau ntxuav.

 

2. Tom qab dyeing, nws yuav tsum tau ntxuav tag nrho kom tsis txhob ntxuav tsis huv.Cov xim ntab ntawm cov xov paj yog yooj yim rau decompose rau hauv sulfuric acid thaum lub sij hawm cia thiab ua rau fiber ntau embrittlement.

 

3. Tom qab dyeing, urea, soda tshauv, sodium acetate, thiab lwm yam yuav tsum tau siv los tiv thaiv embrittlement kev kho mob.

 

4. Cov xov paj yog boiled nrog dej huv ua ntej dyeing, thiab brittleness ntawm cov xov paj boiled nrog dej huv tom qab dyeing yog zoo dua li uas boiled nrog lye.

 

5. Tom qab dyeing, cov xov paj yuav tsum tau qhuav rau lub sijhawm.Vim hais tias cov xov paj ntub yog ib qho yooj yim kom sov thaum lub sij hawm stacking txheej txheem, cov ntsiab lus ntawm cov xov paj los tiv thaiv embrittlement tus neeg sawv cev yog txo, thiab tus nqi pH yog txo, uas yog unfavorable rau anti embrittlement.Tom qab cov xov paj qhuav, nws yuav tsum tau txias txias kom txo qhov kub ntawm cov xov paj mus rau chav sov ua ntej ntim.Vim tias nws tsis txias tom qab ziab thiab ntim tam sim ntawd, cov cua sov tsis yooj yim rau dissipated, uas ua rau kom lub zog ntawm cov xim decomposition thiab acid tiam, thiab ua rau kom muaj fiber ntau embrittlement.

 

6. Anti brittle dub sulfide dye yog xaiv.Formaldehyde thiab chloroacetic acid tau ntxiv rau cov xim no thaum nws tsim.methyl chloride sulfur los tiv thaiv nkig dub ua los ntawm cov xim no tuaj yeem ua kom yooj yim oxidized sulfur atoms rau hauv cov txheej txheem ruaj khov, thiaj li tiv thaiv oxidation ntawm sulfur atoms rau hauv cov kua qaub thiab ua rau cov fiber ntau nkig.

 

Tus nqi nqus ntawmkua sulfur dubyog siab tshaj ntawm cov hmoov, thiab cov dej phwj tuaj tsis muaj sediment impurities, uas zoo heev txo tus nqi ntawm cov dej phwj kho mob thiab yog ib tug kuj ntau environmentally phooj ywg.Ntau cov ntaub ntawv qhia tau hais tias qhov qhuav thiab ntub dej nrawm nrawm ntawm cov kua sulfur dub yog 0.5 qib siab dua li cov hmoov.Cov kua sulfur dub tau tag nrho oxidized thaum lub sij hawm tsim khoom, thiab yuav tsis oxidized thaum thauj / cia.Ordinary sulfur dub yuav tsum tau kho nrog alkali sulfide.Alkali sulfide yog cov metabolite ntawm mirabilite, thiab qhov zoo residual tsis sib npaug, uas qhia ntau tus impurities, thaum lub impurity ntawm cov kua sulfur dub yog yuav luag 0, uas yog ruaj khov dua hmoov sulfur dub, thiab qhov tshwm sim ntawm cov ntaub dyeing yuam kev. qis.

 

Ib puag ncig tus phooj ywg kua sulfur dub yog tsuas yog siv nyob rau hauv denim xov dyeing, embryo daim ntaub dyeing, knitting dyeing, pob dyeing, thiab lwm yam. piv nrog rau lwm yam paj rwb dyes xws li reactive dyes thiab Shilin, nws muaj cov yam ntxwv ntawm tus nqi qis thiab luv luv khiav, thiab tau nce txais los ntawm kev luam ntawv thiab dyeing manufacturers.

 

Piv nrog cov hmoov sulfur dub, kua sulfur dub muaj cov hauv qab no zoo:

 

1. Nws yog ib qho yooj yim rau siv (raws li cov txheej txheem kev ua haujlwm ntawm cov dyes ncaj qha) thiab tuaj yeem ua tiav xim tom qab ntxuav;

 

2. Nws yog qhov yooj yim los kho lub teeb xim, uas tuaj yeem hloov kho los ntawm cov kua vulcanization lossis cov xim ncaj qha;

 

3. Tsis txhob siv alkali sulfide rau txiav;

 

4. Kev tiv thaiv ib puag ncig, ntxhiab tsw me me thiab dej khib nyiab;

 

5. Direct pad dyeing, dip dyeing thiab jigging;

 

6. Noj ntau npaum li koj xav tau raws li qhov kev siv tiag tiag.Cov khoom seem tuaj yeem raug kaw thiab muab tso rau hauv kev siv tom qab lub sijhawm.Nws zam cov khoom pov tseg ntawm cov khoom seem ntawm cov hmoov sulfur dyes vim qhib ntau dhau;

 

7. Lub teeb xim ntawm hmoov sulfur dyes yog qhov ruaj khov, thiab lub tog raj kheej sib txawv yog qhov hnyav, thaum cov kua sulfur dyes tsis muaj qhov tshwm sim no.
