Yuanming hmoov tseem hu ua Glauber's ntsev, thiab nws lub npe scientific yog sodium sulfate.Qhov no yog ib qho ntsev inorganic uas yog ze heev rau cov khoom siv ntawm cov ntsev ntsev.

1. Siv los ua cov dyeing ncaj qha thiab lwm cov neeg ua haujlwm nrawm rau paj rwb dyeing

Thaum dyeing paj rwb nrog dyes ncaj qha, sulfur dyes, vat dyes thiab Yindioxin dyes, sodium sulfate yuav siv tau raws li ib tug dye-promoting tus neeg sawv cev.

Cov dyes no yooj yim rau yaj hauv cov tshuaj dyeing npaj, tab sis tsis yooj yim rau dye paj rwb fibers.Vim tias cov dyeing tsis yooj yim kom dhau, muaj ntau cov dye seem nyob rau hauv ko taw dej.

Qhov sib ntxiv ntawm sodium sulfate tuaj yeem txo qhov solubility ntawm cov xim hauv dej, yog li ua kom cov xim muaj zog ntawm cov xim.Nyob rau hauv txoj kev no, tus nqi ntawm cov xim tuaj yeem txo, thiab cov xim dyed yuav tob zuj zus.

1. Tus nqi ntawm sodium sulfate

Nws nyob ntawm lub zog xim ntawm cov xim uas siv thiab qhov tob ntawm qhov xav tau xim.Tsis txhob ntxiv ntau dhau los yog nrawm dhau, txwv tsis pub cov xim hauv cov tshuaj zas xim yuav ua rau nag thiab ua rau cov xim zas xim rau ntawm daim ntaub.

2. Thaum dyeing paj rwb ntaub

Yuanming hmoov feem ntau ntxiv rau hauv batch hauv 3rd mus rau 4th qib.Vim tias cov tshuaj zas xim yog tuab heev ua ntej dyeing, yog tias nws ntxiv sai, cov dye yuav dye rau ntawm fiber ntau sai heev thiab nws yooj yim los tsim unevenness, yog li dye nws rau ib pliag thiab ces ntxiv.Tsim nyog.

3. Sodium sulfate ua ntej siv

Yuanming hmoov yuav tsum tau tob tob nrog dej ua ntej siv, thiab lim ua ntej muab ntxiv rau hauv da dej dyeing.Nws yog ib qho tsim nyog yuav tsum tau do lub dyeing da dej thiab maj mam ntxiv nws los tiv thaiv ib nrab dyeing da dej los ntawm kev sib cuag nrog ib tug loj npaum li cas ntawm accelerant thiab ua rau cov dyeing rau ntsev.Txheeb xyuas lub luag haujlwm.

4. Sodium sulfate thiab ntsev feem ntau yog siv dye accelerators

Kev xyaum tau ua pov thawj tias hauv kev dyeing ncaj qha, siv sodium sulfate ua tus dye accelerator tuaj yeem tau txais cov xim ci.Cov nyhuv ntawm kev siv lub rooj ntsev yog qhov tsis zoo, uas cuam tshuam nrog kev purity ntawm lub rooj ntsev.Ntxiv nrog rau ntau cov calcium thiab magnesium ions, kev lag luam ntsev kuj muaj hlau ions.Qee cov dyes uas cuam tshuam zoo heev los ntawm cov hlau ions (xws li ncaj qha turquoise xiav GL, thiab lwm yam) siv ntsev ua cov dye accelerant, uas yuav ua rau cov xim grey.

5. Qee tus neeg xav tias tus nqi ntawm lub rooj ntsev yog pheej yig dua

Qee tus neeg xav tias tus nqi ntawm lub rooj ntsev yog pheej yig dua, thiab lub rooj ntsev tuaj yeem siv los hloov Yuanming hmoov.Txawm li cas los xij, nws yog qhov zoo dua los siv Yuanming hmoov rau lub teeb xim dua li cov lus ntsev, thiab rau cov xim tsaus, cov lus ntsev zoo dua.Txawm hais tias tsim nyog, nws yuav tsum tau siv tom qab kev sim.

6. Kev sib raug zoo ntawm sodium sulfate thiab tus nqi ntawm ntsev

Kev sib raug zoo ntawm sodium sulfate thiab ntsev noj yog kwv yees li hauv qab no:

6 qhov chaw anhydrous Na2SO4 = 5 qhov chaw NaCl

12 qhov chaw hydrate Na2SO4 · 10H20 = 5 qhov chaw NaCl

2. Siv raws li ib tug retarder rau ncaj dyeing thiab txhob lo lo ntxhuav dyeing

Daim ntawv thov ntawm cov dyes ncaj qha rau ntawm cov protein fibers feem ntau yog txhob lo lo ntxhuav dyeing, thiab dyeing ceev tau zoo dua li cov kua qaub dyes.Qee cov dyes ncaj qha kuj muaj qhov tso tawm tau zoo heev, yog li lawv feem ntau siv rau cov xim hauv av hauv cov ntaub lo lo ntxhuav luam ntawv.

Direct dyeing ntawm txhob lo lo ntxhuav kuj feem ntau ntxiv me me ntawm sodium sulfate, tab sis lub luag hauj lwm ntawm sodium sulfate yog txawv ntawm cov paj rwb dyeing.Nws tsuas yog ua raws li tus neeg sawv cev dyeing qeeb.

Nco tseg:
1. Dyeing silk nrog dyes ncaj qha.Tom qab sodium sulfate ntxiv, cov nyhuv qeeb-dyeing tshwm sim raws li hauv qab no:

Cov dye ncaj qha R SO3Na dissociates rau hauv sodium ion Na + thiab pigment anion R SO3- nyob rau hauv dej, raws li qhia nyob rau hauv cov nram qab no mis: RSO3Na (interconversion xub nyob rau hauv lub parentheses) Na + R SO3- yuanming hmoov Na2SO4 dissociates rau hauv sodium ion Na + thiab sulfate ion SO4- nyob rau hauv dej -, cov mis hauv qab no: Na2SO4 (interconversion xub nyob rau hauv parentheses) 2Na + RSO4- Nyob rau hauv lub dyeing da dej, lub dye anion R SO3- tuaj yeem ncaj qha dye silk.Thaum ntxiv sodium sulfate, nws yuav dissociate los tsim sodium ion Na +, Lub dissociation ntawm cov xim yog cuam tshuam los ntawm sodium ions;uas yog hais tias, vim hais tias ntawm qhov sib npaug ntawm kev sib raug zoo ntawm cov tshuaj tiv thaiv tom qab ion, nws cuam tshuam los ntawm Na + ntau ion txhaum, uas txo cov dissociation ntawm cov xim, yog li cov dyeing ntawm txhob lo lo ntxhuav yog qeeb.Dyeing nyhuv.

2. Rau cov ntaub dyed nrog dyes ncaj qha, feem ntau siv kho tus neeg saib xyuas Y lossis kho tus neeg sawv cev M (kwv yees li 3 ~ 5g / l, 30% acetic acid 1 ~ 2g / l, kub 60 ℃) rau 30 feeb los txhim kho cov khoom tiav xim ceev. .

4. Siv los ua cov xim av tiv thaiv rau scouring ntawm cov luam tawm thiab dyed silk fabrics

Thaum scouring luam ntawv los yog dyeing silk fabrics, cov dyeing tej zaum yuav tev tawm, thiaj li hais tias nws yuav stain lub av xim los yog lwm yam ntaub ntawv synchronized.Yog hais tias sodium sulfate ntxiv, qhov solubility ntawm cov dye yuav raug txo kom tsawg, yog li tsis muaj kev phom sij ntawm tev tawm cov dye thiab paug cov xim av.Up.
