Indlela yokusebenza ye-starch ether odakeni

Isitashi i-ether wuhlobo lwe-cellulose ether evame ukusetshenziswa njengesengezo odakeni ukuze kuthuthukiswe ukusebenza kwayo.Umsebenzi oyinhloko we-starch ether odakeni ukuthuthukisa ukusebenza kwayo, ukugcinwa kwamanzi, kanye nezakhiwo zokunamathela.Indlela yokusebenza ye-starch ether odakeni ingachazwa kanje:

1. Ukuthuthukiswa kokusebenza: I-ether yesitashi ingathuthukisa ukusebenza kodaka ngokunciphisa i-viscosity yengxube.Lokhu kufezwa ngokukhanyiswa kwama-molecule e-starch ether phezu kwezinhlayiya zikasimende, okunciphisa amashaji azo e-electrostatic futhi kwandise ukuhamba kwawo.Lokhu kunciphisa ukungqubuzana phakathi kwezinhlayiya, kuzivumela ukuthi zihambe ngokukhululeka futhi kalula.Ngenxa yalokho, udaka luba uketshezi oluthe xaxa futhi kube lula ukusebenza ngalo.
2. Ukugcinwa kwamanzi: I-ether yesitashi ingathuthukisa ukugcinwa kwamanzi odongeni ngokwenza ifilimu evikelayo ezungeze izinhlayiya zikasimende.Le filimu ivimbela amanzi engxube ukuthi ahwamuke ngokushesha, okuvumela udaka ukuthi luhlale lusebenza isikhathi eside.Lokhu kubaluleke kakhulu ezimeni ezishisayo nezomile, lapho izinga lokuhwamuka kwamanzi odaka liphezulu.
3. Ukunamathela: I-ether yesitashi ingathuthukisa ukunamathela kodaka ku-substrate ngokwandisa ukubambelela kwayo.Lokhu kufezwa ngokwakhiwa kwezibopho ze-hydrogen phakathi kwama-molecule e-starch ether kanye ne-substrate surface, okwandisa amandla okunamathela okuhlangene.Lokhu kuthuthukisa amandla esibopho esiphelele phakathi kodaka ne-substrate, kunciphisa ubungozi bokuhlukaniswa noma ukwehluleka.

Kafushane, indlela yokusebenza ye-starch ether odakeni isekelwe ekhonweni layo lokuthuthukisa ukusebenza, ukugcinwa kwamanzi, kanye nezakhiwo zokunamathela zengxube.I-starch ether ifinyelela lokhu ngokunciphisa i-viscosity yengxube, yenza ifilimu evikelayo ezungeze izinhlayiya zikasimende, nokwandisa ukuqina kodaka.Ukusetshenziswa kwe-starch ether odakeni kungathuthukisa ukusebenza okuphelele nokuqina kwengxube, okuholela kunqubo yokwakha esebenza kahle futhi ephumelelayo.
