Lub luag haujlwm ntawm glacial acetic acid hauv kev lag luam ntxhua khaub ncaws
1. Acid dissolving muaj nuj nqi hauv stain tshem tawm
Acetic acid raws li cov organic vinegar, nws muaj peev xwm yaj tannic acid, txiv hmab txiv ntoo acid thiab lwm yam organic acid yam ntxwv, nyom stains, kua txiv stains (xws li txiv hmab txiv ntoo hws, kua txiv hmab txiv ntoo, kua txiv lws suav, kua txiv hmab txiv ntoo, thiab lwm yam), tshuaj stains, kua txob. roj thiab lwm yam stains, cov stains no muaj cov organic vinegar cov khoom xyaw, acetic acid ua cov stain remover, tuaj yeem tshem tawm cov organic acid cov khoom xyaw hauv cov stains, xws li cov khoom xyaw xim hauv cov stains, Tom qab ntawd nrog kev kho oxidative bleaching, tag nrho cov tuaj yeem raug tshem tawm.Tsis tas li ntawd, thaum ntxhua khaub ncaws hnyav, feem ntau vim tias cov dej yaug tsis huv txaus, cov khaub ncaws yuav qhuav los yog nplhaib tom qab ziab.Yog tias nws tsis loj heev, nws tuaj yeem txau nrog dej uas muaj acetic acid los yog so nrog cov phuam da dej acetic acid kom tshem tawm cov ziab thiab cov nplhaib stains.
2. Neutralize residual alkali
Acetic acid nws tus kheej tsis muaj zog acidic thiab tuaj yeem nruab nrab nrog cov hauv paus.
(1) Hauv kev tshem tawm cov tshuaj lom neeg, kev siv cov cuab yeej no tuaj yeem tshem tawm cov alkaline stains, xws li kas fes stains, tshuaj yej stains, thiab qee cov tshuaj stains.
(2) Qhov nruab nrab ntawm acetic acid thiab alkali tuaj yeem rov ua kom cov khaub ncaws tsis zoo los ntawm kev cuam tshuam ntawm alkali.
(3) Kev siv cov kua qaub tsis muaj zog ntawm acetic acid kuj tuaj yeem ua kom cov tshuaj bleaching ntawm qee qhov txo cov tshuaj bleach hauv cov txheej txheem bleaching, vim hais tias qee qhov txo cov tshuaj dawb tuaj yeem ua kom cov decomposition nyob rau hauv cov kua txiv hmab txiv ntoo thiab tso cov tshuaj bleaching, yog li ntawd, kho tus nqi PH. ntawm cov tshuaj bleaching nrog acetic acid tuaj yeem ua kom cov txheej txheem bleaching.
(4) Cov kua qaub ntawm acetic acid yog siv los kho cov kua qaub thiab alkali ntawm cov khaub ncaws hnav, thiab cov khoom siv hauv khaub ncaws raug kho nrog cov kua qaub, uas tuaj yeem kho lub xeev mos ntawm cov khoom siv khaub ncaws.
(5) Wool fiber ntaub, nyob rau hauv cov txheej txheem ironing, vim lub ironing kub yog siab dhau lawm, ua rau kev puas tsuaj rau cov ntaub plaub fiber ntau, ua rau lub teeb tshwm sim, nrog dilute acetic acid tuaj yeem kho cov ntaub so ntswg fiber ntau, yog li ntawd, acetic acid kuj tuaj yeem ua tau siv los daws qhov teeb meem tshwm sim los ntawm ironing.
3. khoom xim kom tsis txhob fading
Qee cov khaub ncaws tau ploj mus, cov khaub ncaws tau muab tso rau hauv cov tshuaj ntxuav tes, ntau cov dyes yuav yaj, nws nyuaj rau kev ntxuav txuas ntxiv.Acetic acid tuaj yeem siv rau kev kho mob dye lifting.Ua ntej tshaj plaws, tsis txhob tso tseg kev ntxhua khaub ncaws, thiab ua kom tiav cov khaub ncaws ntxhua kom sai li sai tau.Tom qab tshem tawm cov khaub ncaws, tsis txhob nchuav cov dej uas muaj cov zas, tam sim ntawd ntxiv ib qho nyiaj ntawm glacial acetic acid, tam sim ntawd tom qab nplawm cov khaub ncaws rov qab rau hauv dej, soak rau 10-20 feeb, thiab feem ntau tig thaum lub sij hawm soaking. tiv thaiv tsis sib xws.Tom qab kev kho mob, cov xim nyob rau hauv dej yog "tso rov qab" rau cov khaub ncaws.Tom qab ntawd, txuas ntxiv yaug nrog dej uas muaj acetic acid, lub cev qhuav dej thiab qhuav.Qhov no tuaj yeem tsis tsuas yog ua kom tsis txhob muaj cov khaub ncaws fading, tab sis kuj ua rau cov khaub ncaws xim zoo nkauj li tshiab.Tshwj xeeb tshaj yog rau cov ntaub lo lo ntxhuav, cov dej khov acetic acid yog siv los kho cov xim, tiv thaiv cov kab lo lo ntxhuav fiber ntau, txo nws cov fading, thiab txuas ntxiv lub neej hnav.
Lub luag haujlwm ntawm glacial acetic acid hauv textile printing thiab dyeing
1. nyob rau hauv cov txheej txheem dyeing, glacial acetic acid tuaj yeem ua lub luag haujlwm hauv kev kho cov dyeing.Thaum lub sij hawm dyeing txheej txheem, cov dyeing yuav tsum tau chemically react nrog cov fiber ntau molecules thiaj li yuav ruaj khov rau cov fiber.Raws li tus neeg sawv cev nruab nrab, glacial acetic acid tuaj yeem kho tus nqi pH ntawm cov xim thiab fiber ntau, kom nws nyob rau hauv cov tshuaj tiv thaiv zoo.
2. glacial acetic acid kuj tuaj yeem tsim ib qho chaw ruaj khov nrog cov dyes, ua rau muaj kev sib khi ntawm cov xim molecules thiab fiber ntau molecules, yog li txhim kho qhov ruaj khov thiab ruaj khov ntawm dyeing.
3. Hauv textile xov, ntxiv qhov tsim nyog ntawm glacial acetic acid tuaj yeem tsim ntau ester bonds ntawm fiber ntau molecules, yog li txhim kho qhov wrinkle tsis kam thiab washable kuj ntawm textiles.
Daim ntawv thov ntawm glacial acetic acid nyob rau hauv textile printing thiab dyeing kev lag luam
1. Paj rwb dyeing
Nyob rau hauv cov txheej txheem ntawm paj rwb dyeing, glacial acetic acid yog siv los ua tus pab los pab cov dyeing nkag mus rau hauv paj rwb fiber zoo dua thiab txhim kho cov nyhuv dyeing.Tsis tas li ntawd, nws tseem tuaj yeem siv los kho tus nqi pH ntawm cov tshuaj zas xim los txhawb kev sib xyaw ntawm cov xim thiab paj rwb fiber ntau.
2. ntaub plaub dyeing
Wool fibers muaj ib txheej roj rau ntawm qhov chaw, uas nyuaj rau dyes nkag mus.Hauv qhov no, glacial acetic acid yog siv los ua tus neeg sawv cev pabcuam kom tshem tawm cov roj ntawm cov ntaub plaub fiber ntau thiab txhim kho permeability thiab dyeing nyhuv ntawm cov xim.
3. Polyester dyeing
Polyester yog cov khoom siv hluavtaws uas yog hydrophobic thiab nyuaj rau nkag los ntawm dyes.Txhawm rau txhim kho cov nyhuv dyeing ntawm polyester, glacial acetic acid yog siv los ua ib qho ntxiv los pab cov dyeing nkag mus rau hauv cov fiber ntau zoo dua.
4. Silk dyeing
Silk yog ib qho khoom siv me me uas muaj kev nkag siab zoo rau kev hloov pauv hauv qhov kub thiab txias.Nyob rau hauv tus txheej txheem ntawm txhob lo lo ntxhuav dyeing, glacial acetic acid yog siv los ua tus pab tswj qhov kub thiab pH tus nqi ntawm cov tshuaj dyeing kom paub meej cov nyhuv dyeing thiab zoo.
5. txheej txheem luam ntawv
Nyob rau hauv cov txheej txheem luam ntawv, glacial acetic acid yog siv los ua tus neeg sawv cev ntawm cov kua qaub luam ntawv los txhim kho cov nyhuv luam ntawv thiab precision.Tsis tas li ntawd, nws tseem tuaj yeem siv los kho tus nqi pH ntawm cov ntawv luam tawm los txhawb kev sib xyaw ntawm cov ntawv luam tawm thiab cov fiber ntau.
