Lub luag haujlwm ntawm glacial acetic acid hauv kev ntxuav thiab textile dyeing

Lub luag haujlwm ntawm glacial acetic acid hauv kev lag luam ntxhua khaub ncaws

1. Kev ua haujlwm ntawm cov kua qaub hauv kev tshem tawm cov xim av
Acetic acid ua ib yam kua txiv hmab txiv ntoo organic, nws tuaj yeem yaj cov tannic acid, kua txiv hmab txiv ntoo acid thiab lwm yam organic acid yam ntxwv, cov nyom stains, kua txiv hmab txiv ntoo stains (xws li txiv hmab txiv ntoo hws, kua txiv qaub, kua txiv lws suav, kua dej qab zib, thiab lwm yam), cov tshuaj stains, roj chili thiab lwm yam stains, cov stains no muaj cov khoom xyaw organic vinegar, acetic acid ua ib qho tshuaj tshem tawm cov stains, tuaj yeem tshem tawm cov khoom xyaw organic acid hauv cov stains, zoo li cov khoom xyaw pigment hauv cov stains, Tom qab ntawd nrog kev kho oxidative bleaching, txhua yam tuaj yeem tshem tawm. Ntxiv mus, thaum ntxuav khaub ncaws hnyav, feem ntau vim tias kev yaug tsis txaus, cov khaub ncaws yuav qhuav lossis nplhaib tom qab ziab. Yog tias nws tsis loj heev, nws tuaj yeem txau nrog dej uas muaj acetic acid lossis so nrog phuam nrog dej acetic acid kom tshem tawm cov ziab thiab nplhaib stains.

2. Tshem tawm cov alkali seem
Acetic acid nws tus kheej yog weakly acidic thiab tuaj yeem neutralized nrog cov hauv paus.
(1) Hauv kev tshem tawm cov xim pleev xim, kev siv cov khoom no tuaj yeem tshem tawm cov xim pleev xim alkaline, xws li cov xim pleev xim kas fes, cov xim pleev xim tshuaj yej, thiab qee cov xim pleev xim tshuaj.
(2) Kev ua kom tsis muaj zog ntawm acetic acid thiab alkali kuj tseem tuaj yeem kho qhov xim ntawm cov khaub ncaws uas tshwm sim los ntawm kev cuam tshuam ntawm alkali.
(3) Kev siv cov kua qaub tsis muaj zog ntawm acetic acid kuj tseem tuaj yeem ua kom cov tshuaj dawb ntawm qee cov tshuaj dawb txo qis hauv cov txheej txheem dawb, vim tias qee cov tshuaj dawb txo qis tuaj yeem ua kom cov khoom lwj sai dua nyob rau hauv cov xwm txheej vinegar thiab tso cov tshuaj dawb, yog li ntawd, kho qhov PH ntawm cov tshuaj dawb nrog acetic acid tuaj yeem ua kom cov txheej txheem dawb sai dua.
(4) Cov kua qaub ntawm acetic acid yog siv los kho cov kua qaub thiab alkali ntawm cov ntaub khaub ncaws, thiab cov ntaub khaub ncaws raug kho nrog kua qaub, uas tuaj yeem kho qhov mos ntawm cov ntaub khaub ncaws.
(5) Cov ntaub plaub mos mos, thaum lub sijhawm ironing, vim tias qhov kub ntawm ironing siab dhau, ua rau cov plaub mos mos puas tsuaj, ua rau muaj teeb meem, nrog rau dilute acetic acid tuaj yeem rov qab kho cov ntaub plaub mos mos, yog li ntawd, acetic acid kuj tseem siv tau los daws qhov teeb meem los ntawm ironing.

3. xim tawv kom tiv thaiv kev ploj mus
Muaj tej khaub ncaws uas ploj tag lawm, cov khaub ncaws twb muab tso rau hauv lub tshuab ntxuav khaub ncaws lawm, yuav muaj ntau yam xim yuav yaj, ua rau nyuaj rau ntxuav ntxiv. Acetic acid siv tau los kho cov xim kom zoo nkauj. Ua ntej tshaj plaws, tsis txhob tsum ntxuav, thiab ntxuav khaub ncaws sai li sai tau. Tom qab muab cov khaub ncaws tawm, tsis txhob nchuav cov dej uas muaj xim tawm, tam sim ntawd ntxiv cov kua qaub glacial acetic acid kom txaus, tom qab do cov khaub ncaws rov qab rau hauv dej, tsau rau 10-20 feeb, thiab feem ntau tig thaum lub sijhawm tsau kom tiv thaiv tsis sib npaug. Tom qab kho, cov xim hauv dej "nqa rov qab" rau cov khaub ncaws. Tom qab ntawd, txuas ntxiv yaug nrog dej uas muaj acetic acid, ua kom qhuav thiab qhuav. Qhov no tsis tsuas yog tiv thaiv kev ploj ntawm cov khaub ncaws xwb, tab sis kuj ua rau cov xim khaub ncaws zoo nkauj li tshiab. Tshwj xeeb tshaj yog rau cov ntaub txhob lo lo ntxhuav, kua qaub ice acetic acid siv los kho cov xim, tiv thaiv cov fiber ntawm cov txhob lo lo ntxhuav, txo nws qhov ploj, thiab ntev lub neej hnav.

Lub luag haujlwm ntawm glacial acetic acid hauv textile printing thiab dyeing
1. Hauv cov txheej txheem dyeing, glacial acetic acid tuaj yeem ua lub luag haujlwm hauv kev kho cov xim zas. Thaum lub sijhawm txheej txheem dyeing, cov xim zas yuav tsum tau ua tshuaj lom neeg nrog cov tshuaj fiber kom ruaj khov rau cov fiber. Ua tus neeg sawv cev neutralizing, glacial acetic acid tuaj yeem kho qhov pH ntawm cov xim zas thiab fiber, yog li nws nyob rau hauv qhov xwm txheej zoo.
2. glacial acetic acid kuj tseem tuaj yeem tsim ib qho kev sib xyaw ua ke nrog cov xim, ua rau lub zog khi ntawm cov xim molecules thiab cov fiber molecules, yog li txhim kho qhov ruaj khov thiab ua haujlwm ntev ntawm cov xim.
3. Hauv kev ua tiav cov ntaub, ntxiv cov kua qaub glacial acetic acid kom tsim tau ntau cov ester bonds ntawm cov fiber molecules, yog li txhim kho qhov tsis kam ntawm wrinkle thiab ntxuav tau ntawm cov ntaub.

Daim ntawv thov ntawm glacial acetic acid hauv kev lag luam textile printing thiab dyeing
1. Kev zas xim paj rwb
Thaum lub sijhawm zas xim paj rwb, glacial acetic acid yog siv los ua tus pab cuam los pab cov xim nkag mus rau hauv cov paj rwb zoo dua thiab txhim kho cov nyhuv zas xim. Tsis tas li ntawd, nws kuj tseem siv tau los kho qhov pH ntawm cov kua xim kom txhawb kev sib xyaw ua ke ntawm cov xim thiab paj rwb.
2. Kev zas xim plaub yaj
Cov xov paj rwb muaj ib txheej roj ntawm qhov chaw, uas nyuaj rau cov xim nkag mus. Hauv qhov no, glacial acetic acid yog siv los ua tus neeg sawv cev pabcuam kom tshem tawm cov roj ntawm qhov chaw ntawm cov xov paj rwb thiab txhim kho qhov permeability thiab dyeing effect ntawm cov xim.
3. Kev zas xim Polyester
Polyester yog ib hom fiber ua los ntawm cov khoom siv uas tsis muaj dej thiab nyuaj rau cov xim nkag mus. Yuav kom txhim kho cov nyhuv ntawm polyester, glacial acetic acid yog siv los ua ib qho khoom ntxiv los pab cov xim nkag mus rau hauv cov fiber zoo dua.
4. Kev zas xim txhob lo lo ntxhuav
Txhob lo lo ntxhuav yog ib daim ntaub mos mos uas rhiab heev rau qhov hloov pauv ntawm qhov kub thiab pH. Hauv cov txheej txheem ntawm kev zas xim txhob lo lo ntxhuav, glacial acetic acid yog siv los ua tus pab tswj qhov kub thiab pH ntawm cov tshuaj zas xim kom ntseeg tau tias cov nyhuv zas xim thiab zoo.
5. Cov txheej txheem luam ntawv
Hauv cov txheej txheem luam ntawv, glacial acetic acid yog siv los ua tus neeg sawv cev pabcuam ntawm cov kua qaub luam ntawv los txhim kho cov nyhuv luam ntawv thiab kev ua haujlwm raug. Tsis tas li ntawd, nws kuj tseem siv tau los kho tus nqi pH ntawm cov ntawv luam ntawv los txhawb kev sib xyaw ua ke ntawm cov ntawv luam ntawv thiab cov fiber.
