Daim ntawv thov

Thaum dyeing paj rwb nrog dyes ncaj qha, sulfide dyes, vat dyes, thiab indocyanin dyes, sodium sulfate yuav siv tau raws li ib tug dye promoter. Sodium sulfate rau luam ntawv thiab dyeing yog yooj yim soluble nyob rau hauv lub formulated dye tov, tab sis nws tsis yooj yim rau dye paj rwb fibers. Vim qhov nyuaj ntawm absorbing cov dye tag nrho, muaj ntau cov residual dyes nyob rau hauv dej. Ntxiv sodium sulfate tuaj yeem txo qhov solubility ntawm dyes hauv dej, yog li ua kom cov xim muaj zog ntawm cov dyes. Nyob rau hauv txoj kev no, tus nqi ntawm cov dye siv yuav txo tau thaum cov xim ntawm cov khoom dyed tob.

1. Tus nqi ntawm sodium sulfate rau kev luam ntawv thiab dyeing nyob ntawm lub zog xim ntawm cov dyes siv thiab qhov tob ntawm cov xim uas xav tau. Nws yuav tsum tsis txhob ntxiv ntau dhau los yog sai heev; Txwv tsis pub, cov dyes nyob rau hauv cov tshuaj dye yuav precipitate, ua rau stains ntawm daim ntaub nto.

2. Thaum lub sij hawm yob dyeing ntawm paj rwb ntaub, sodium sulfate feem ntau yog ntxiv nyob rau hauv batch nyob rau hauv peb mus rau plaub kis. Vim yog cov tshuaj pleev xim tuab ua ntej dyeing, yog ntxiv sai sai, cov dye yuav dye cov fiber ntau sai heev, ua rau tsis sib xws. Yog li ntawd, nws raug nquahu kom zas xim rau ib lub sijhawm ua ntej nws ntxiv.

3. Ua ntej siv, sodium sulfate yuav tsum tau diluted kom huv si nrog dej thiab lim ua ntej muab ntxiv rau hauv da dej dyeing. Nws tseem yog ib qho tsim nyog yuav tsum tau do cov dye da dej thaum maj mam ntxiv nws los tiv thaiv cov dye da dej hauv zos los ntawm salting tawm vim yog kev sib cuag nrog ntau tus dye promoter.

4. Sodium sulfate thiab ntsev feem ntau yog siv los ua cov tshuaj pleev xim. Kev xyaum tau ua pov thawj tias nyob rau hauv dyeing ncaj qha thiab do-frying dyeing, siv sodium sulfate raws li ib tug dye promoter tuaj yeem tau txais cov xim ci. Cov nyhuv ntawm kev siv ntsev yog qhov tsis zoo, uas cuam tshuam nrog kev ua kom huv ntawm ntsev. Ntxiv nrog rau muaj ntau cov calcium thiab magnesium plasma, cov ntsev dav dav kuj muaj cov hlau ions. Qee cov dyes uas cuam tshuam zoo heev los ntawm cov hlau ions (xws li Direct Turquoise Blue GL, thiab lwm yam) tuaj yeem ua rau cov xim tsis zoo thaum siv ntsev ua cov tshuaj pleev xim.

5. Qee tus neeg kuj ntseeg tias ntsev yog pheej yig dua thiab siv tau los hloov cov sodium sulfate. Txawm li cas los xij, thaum dyeing lub teeb xim, siv sodium sulfate zoo dua ntsev, thaum thaum dyeing tsaus xim, siv ntsev zoo dua. Txhua yam uas tsim nyog yuav tsum tau sim ua ntej thov.

6. Kev sib raug zoo ntawm sodium sulfate thiab ntsev noj yog kwv yees li hauv qab no: 6 qhov chaw anhydrous Na2SO4=5 ntu NaCl 12 qhov chaw hydrate Na2SO4 "10H20=5 ntu NaCl.
