Indima ye-glacial acetic acid ekuhlanzeni nasekudayini izindwangu
Indima ye-glacial acetic acid embonini yokuwasha
1. Umsebenzi wokuncibilikisa i-asidi ekususweni kwamabala
I-Acetic acid njengeviniga ephilayo, ingancibilikisa i-tannic acid, i-fruit acid nezinye izici ze-organic acid, amabala otshani, amabala ejusi (njengejusi lezithelo, ijusi le-melon, ijusi likatamatisi, ijusi lesiphuzo esibandayo, njll.), amabala emithi, uwoyela we-chili kanye namanye amabala, la mabala aqukethe izithako zeviniga ephilayo, i-acetic acid njengesisusi samabala, ingasusa izithako ze-organic acid emabala, njengoba izithako ze-pigment emabala, Ngemuva kwalokho ngokwelashwa kwe-oxidative bleaching, konke kungasuswa. Ngaphezu kwalokho, lapho ugeza izingubo ezisindayo, ngokuvamile ngenxa yokuthi ukuhlanza akukanele ngokwanele, izingubo zizoma noma zikhale ngemva kokomiswa. Uma kungekubi kakhulu, ingafuthwa ngamanzi aqukethe i-acetic acid noma isulwe ngethawula ngamanzi e-acetic acid ukususa amabala okomisa kanye namabala endandatho.
2. Nciphisa i-alkali esele
I-Acetic acid ngokwayo ayina-asidi eningi futhi ingasuswa ngezisekelo.
(1) Ekususweni kwamabala amakhemikhali, ukusetshenziswa kwalesi sici kungasusa amabala e-alkaline, njenge-coffee stains, amabala etiye, kanye namabala athile ezidakamizwa.
(2) Ukungaguquguquki kwe-acetic acid kanye ne-alkali kungabuyisela nokushintsha kombala kwezingubo okubangelwa yithonya le-alkali.
(3) Ukusetshenziswa kwe-asidi ebuthakathaka ye-acetic acid kungasheshisa ukusabela kokumhlophe kwe-bleach ethile yokunciphisa enkambisweni yokumhlophe, ngoba i-bleach ethile yokunciphisa ingasheshisa ukubola ngaphansi kwezimo zeviniga futhi ikhulule i-bleaching factor, ngakho-ke, ukulungisa inani le-PH lesisombululo sokumhlophe nge-acetic acid kungasheshisa inqubo yokumhlophe.
(4) I-asidi ye-acetic acid isetshenziselwa ukulungisa i-asidi ne-alkali yendwangu yezingubo, futhi impahla yezingubo iphathwa nge-asidi, engabuyisela isimo esithambile sempahla yezingubo.
(5) Indwangu yefayibha yoboya, enkambisweni yoku-ayina, ngenxa yokushisa koku-ayina okuphezulu kakhulu, okuholela ekulimaleni kwefayibha yoboya, okuholela ekulimaleni kwento ekhanyayo, nge-acetic acid encibilikisiwe ingabuyisela izicubu zefayibha yoboya, ngakho-ke, i-acetic acid ingasetshenziswa futhi ukubhekana nento ekhanyayo ebangelwa uku-ayina.
3. umbala oqinile ukuvimbela ukufiphala
Ezinye izingubo ziphelelwe amandla kakhulu, izingubo zisanda kufakwa emshinini wokuwasha, inani elikhulu lamadayi lizoncibilika, kunzima ukuqhubeka nokuwasha. I-Acetic acid ingasetshenziswa ekwelapheni ukuphakamisa udayi. Okokuqala, ungayeki ukuwasha, bese uqedela ukuwasha izingubo ngokushesha okukhulu. Ngemva kokukhipha izingubo, ungathululi amanzi aqukethe udayi, engeza ngokushesha inani elifanele le-glacial acetic acid, ngokushesha ngemva kokuxubha izingubo zibuyele emanzini, zicwilise imizuzu eyi-10-20, bese uvame ukujika ngesikhathi sokucwilisa ukuze uvimbele ukungalingani. Ngemva kokwelashwa, udayi osemanzini "uyaphakanyiswa" ezingutsheni. Ngemva kwalokho, qhubeka ugeza ngamanzi aqukethe i-acetic acid, ukuphelelwa amanzi emzimbeni bese womile. Lokhu ngeke nje kumise ukufiphala kwezingubo ngempumelelo, kodwa futhi kwenze umbala wezingubo ube muhle njengomusha. Ikakhulukazi ezindwangu zesilika, i-ice acetic acid isetshenziselwa ukulungisa umbala, ukuvikela i-fiber ebusweni besilika, ukunciphisa ukufiphala kwayo, nokwandisa isikhathi sokugqokwa.
Indima ye-glacial acetic acid ekunyatheliseni nasekudayeni izindwangu
1. enkambisweni yokudaya, i-glacial acetic acid ingadlala indima ekulungiseni udayi. Ngesikhathi senqubo yokudaya, udayi udinga ukusabela ngamakhemikhali nama-molecule e-fiber ukuze unamathele ngokuqinile ku-fiber. Njenge-ejenti yokudaya, i-glacial acetic acid ingalungisa inani le-pH phakathi kodayi ne-fiber, ukuze ibe sesimweni esihle sokusabela.
2. i-glacial acetic acid ingakha futhi inkimbinkimbi ezinzile enamadayi, ikhulise amandla okubopha ama-molecule edayi nama-molecule e-fiber, ngaleyo ndlela ithuthukise ukuqina nokuqina kokudayi.
3. Ekuqedeni indwangu, ukwengeza inani elifanele le-glacial acetic acid kungakha izibopho eziningi ze-ester phakathi kwama-molecule e-fiber, ngaleyo ndlela kuthuthukiswe ukumelana kwemibimbi kanye nokumelana nokugezwa kwezindwangu.
Icala lokusetshenziswa kwe-glacial acetic acid embonini yokunyathelisa nokufaka udayi yendwangu
1. Ukudaya ukotini
Enkambisweni yokudaya ikotini, i-glacial acetic acid isetshenziswa njengomsizi ukusiza idayi ingene kwi-fibre yekotini kangcono futhi ithuthukise umphumela wokudaya. Ngaphezu kwalokho, ingasetshenziswa futhi ukulungisa inani le-pH lesisombululo sedayi ukukhuthaza inhlanganisela yedayi ne-fibre yekotini.
2. Ukudaya uboya
Imicu yoboya inengqimba yamafutha ebusweni, okunzima ukuthi amadayi angene. Kulesi simo, i-glacial acetic acid isetshenziswa njenge-ejenti ewusizo ukususa amafutha ebusweni be-fiber yoboya futhi kuthuthukiswe ukungena kanye nomphumela wokudaya wedayi.
3. Ukudaya i-polyester
I-Polyester iyi-fiber yokwenziwa engangeni manzi futhi kunzima ukuyifaka ngamadayi. Ukuze kuthuthukiswe umphumela wokudaya we-polyester, i-glacial acetic acid isetshenziswa njengesithasiselo ukusiza idayi ingene kangcono ku-fiber.
4. Ukudaya usilika
Isilika iyindwangu ethambile ezwela kakhulu ekushintsheni kwezinga lokushisa kanye ne-pH. Enkambisweni yokudaya isilika, i-glacial acetic acid isetshenziswa njengomsizi wokulawula izinga lokushisa kanye nenani le-pH lesisombululo sokudaya ukuqinisekisa umphumela kanye nekhwalithi yokudaya.
5. Inqubo yokuphrinta
Enkambisweni yokunyathelisa, i-glacial acetic acid isetshenziswa njenge-ejenti esekelayo ye-acid printing paste ukuthuthukisa umphumela wokunyathelisa kanye nokunemba. Ngaphezu kwalokho, ingasetshenziswa futhi ukulungisa inani le-pH le-printing paste ukukhuthaza inhlanganisela ye-printing paste kanye ne-fiber.
