Tsis txhob hnov ​​​​qab txog kev cuam tshuam ntawm dej zoo ntawm textile printing thiab dyeing!

Hauv kev luam ntawv thiab dyeing factories, vim muaj cov dej sib txawv, cov dej zoo kuj txawv. Feem ntau, cov chaw luam ntawv thiab dyeing feem ntau siv cov dej saum npoo av, dej hauv av lossis dej kais dej.

Cov dej tsis muaj dej tsis zoo muaj ntau yam tshuaj lom neeg, xws li calcium, magnesium, hlau, sodium, carbonate, sulfate thiab chloride, uas yuav muaj kev cuam tshuam zoo rautextiledyeing.

Qhov zoo ntawm textile printing thiab dyeing muaj tej yam yuav tsum tau ntawm dej zoo. Cov dej tawv yuav cuam tshuam rau cov nyhuv bleaching thiab ua rau cov dyeing tsis sib xws, txhais tes tsis zoo thiab yellowing ntawm cov ntaub. Tab sis ntxiv dej softener yuav ua rau kom ntau npaum li cas ntawm caustic soda thiab lwm yam additives.

Cov calcium thiab magnesium, uas yog insoluble nyob rau hauv dej, yuav tso rau ntawm ntaub thiab tsim incrustation nyob rau hauv alkali tov rau txuas mus rau cov cuab yeej hindering ntau lawm. Thaum cov hlau thiab manganese ntsev nyob rau hauv dej tshaj tus qauv, nws yog ib qho yooj yim los tsim xeb me ntsis thiab catalyze lub oxidation ntawm paj rwb fibers thaum boiling thiab scouring. Thaum siv cov oxidizing tus neeg sawv cev hauv cov txheej txheem bleaching, hlau thiab manganese ntsev kuj tseem yuav ua rau lub decomposition ntawm bleaching agent.

Thaum twgdyeingNrog reactive dyes, lub zog ntawm hardness ntawm dej tsis tseem ceeb. Tab sis thaum dyeing nylon nrog acid dyes, lub zog ntawm lub hardness ntawm dej tsis tseem ceeb. Cov dej tawv dhau lawm yuav tsis tsuas yog ua rau cov xim thiab ci ntsa iab ntawm cov ntaub tsis zoo, tab sis CI hauv dej kuj muaj txiaj ntsig zoo rau kev dyeing.

Cov khib nyiab tshem tawm hauv cov dej tawv yuav cuam tshuam rau cov xim dawb ntawm cov tshuaj dawb. Thaum dyeing cheese, nws yog ib qho yooj yim los txo qhov ci ntsa iab ntawm sab hauv thiab sab nrauv ntawm cov xov paj cheese. Tus nqi pH dej siab yuav cuam tshuam rau qib khoom ntawm cov ntaub hauv cov xim lub teeb. Qhov ntawd yog vim tias nyob rau hauv alkali mob, cov dyes ntxiv yuav raug kho, ua rau tsis zoo sib xws thiab dyeing chaw.

Yog tias tus nqi pH ntawm cov dej siab dhau lawm, nws yuav ua rau cov dyes hydrolyze hauv cov txheej txheem soaping, uas yuav ua rau cov khoom tsis zoo. Thiab txawm nyob rau hauv cov txheej txheem softening, nws yuav ua rau daim ntaub pH tshaj tus qauv.

Cov hlau ions ntau dhau yuav ua rau xim xim, dyeing me ntsis thiab bleak xim ntxoov ntxoo. Ntau tshaj manganese ion yog qhov laj thawj tseem ceeb ntawm yellowing ntawm bleached fabrics.

Cov dej tawv yuav cuam tshuam qhov ci ntawm cov xim thiab yuav ua rau fouling ntawm tshav kub exchangers. Nws muaj kev siv zog siab. Dab tsi ntxiv, calcium thiab magnesium ions thiab sodium carbonate yuav tsim cov sediment insoluble, uas yuav ua rau alkali me ntsis.
