46509 Impuphu Ehlakazayo
Izici & Izinzuzo
- Ukuzinza okuhle kakhulu nokuhlakazeka. Ingasetshenziswa njenge-colloid evikelayo ohlelweni lokudaya.
- Izinzile ku-asidi, i-alkali, i-electrolyte namanzi aqinile.
- I-solute kalula emanzini. Igwebu eliphansi.
- Kulula ukuyisebenzisa.

Izimiso zokudaya
Inhloso yokudaya ukukhiqiza umbala ofanayo we-substrate ngokuvamile ukuze uhambisane nombala okhethwe kusengaphambili. Umbala kufanele ufane kuyo yonke i-substrate futhi ube nomthunzi oqinile ngaphandle kokungalingani noma ukushintsha komthunzi phezu kwayo yonke i-substrate. Kunezici eziningi ezizothonya ukubukeka komthunzi wokugcina, okuhlanganisa: ukuthungwa kwe-substrate, ukwakhiwa kwe-substrate (kokubili amakhemikhali nangokwenyama), ukwelashwa kwangaphambili okufakwa ku-substrate ngaphambi kokudaya kanye nokwelashwa ngemuva kokusetshenziswa ngemuva kokudaya. inqubo. Ukusetshenziswa kombala kungafinyelelwa ngezindlela eziningi, kodwa izindlela ezintathu ezivame kakhulu ukudaya okuphumayo (i-batch), okuqhubekayo (i-padding) nokuphrinta.
Odayi be-Vat
Lawa madayi empeleni awancibiliki emanzini futhi aqukethe okungenani amaqembu amabili e-carbonyl (C=O) avumela odayi ukuthi baguqulwe ngendlela yokunciphisa ngaphansi kwezimo ze-alkaline babe 'inhlanganisela ye-leuco' encibilika emanzini. Kuleli fomu lapho udayi uthathwa yi-cellulose; kulandela ukukhishwa kwe-oxidation okwalandela isakhi se-leuco sivuselela isimo somzali, udayi we-vat ongancibiliki, ngaphakathi kwefayibha.
Udayi we-vat wemvelo obaluleke kakhulu i-Indigo noma i-Indigotin etholakala njenge-glucoside yayo, i-Indican, ezinhlotsheni ezihlukahlukene ze-indigo plant indigofera. Odayi be-Vat basetshenziswa lapho ukukhanya okuphakeme kakhulu nokushesha okumanzi kuyadingeka.
Okuphuma ku-indigo, ikakhulukazi ama-halogenated (ikakhulukazi ama-substituents e-bromo) ahlinzeka ngamanye amakilasi odayi we-vat afaka: i-indigoid ne-thioindigoid, i-anthraquinone (i-indanthrone, i-flavanthrone, i-pyranthone, i-acylaminoanthraquinone, i-anthramide, i-dibenzathrone ne-carbazole).
