Ukusetshenziswa Kwesitashi Ether Emikhiqizweni Esekelwe Usimende

Isitashi ether wuhlobo lwe-Hydroxypropyl starch ether esetshenziswa kakhulu njengesengezo emikhiqizweni esekwe usimende njengodaka, ukhonkolo, nama-grouts.Umsebenzi oyinhloko we-starch ether kule mikhiqizo ukuthuthukisa ukusebenza kwayo, ukugcinwa kwamanzi, kanye nezakhiwo zokunamathela.Ukusetshenziswa kwe-starch ether emikhiqizweni esekwe kusimende kungachazwa kanje:

1. Ukuthuthukiswa kokusebenza: Isitashi se-ether singathuthukisa ukusebenza kwemikhiqizo esekwe kusimende ngokunciphisa ukubukeka kwayo.Lokhu kufezwa ngokukhanyiswa kwama-molecule e-starch ether phezu kwezinhlayiya zikasimende, okunciphisa amashaji azo e-electrostatic futhi kwandise ukuhamba kwawo.Lokhu kuvumela izinhlayiya zikasimende ukuthi zihambe ngokukhululeka, okuholela ekubeni kube noketshezi oluthe xaxa futhi kube lula ukusebenza ngengxube.
2. Ukugcinwa kwamanzi: I-ether yesitashi ingathuthukisa ukugcinwa kwamanzi kwemikhiqizo esekwe usimende ngokwenza ifilimu evikelayo ezungeze izinhlayiya zikasimende.Le filimu ivimbela amanzi engxube ukuthi ahwamuke ngokushesha, okuvumela umkhiqizo osekelwe kusimende ukuthi uhlale usebenza isikhathi eside.Lokhu kubaluleke kakhulu ezimeni ezishisayo nezomile, lapho izinga lokuhwamuka kwamanzi aphuma kumkhiqizo osekelwe usimende liphezulu.
3. Ukunamathela: I-ether yesitashi ingathuthukisa ukunamathela kwemikhiqizo esekwe kusimende ku-substrate ngokwandisa ukuqina 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 komkhiqizo osekelwe kusimende kanye ne-substrate, kunciphisa ubungozi bokuhlukaniswa noma ukwehluleka.
4. Ukumelana nokuqhekeka: Isitashi i-ether ingathuthukisa ukumelana nokuqhekeka kwemikhiqizo esekwe kusimende ngokuthuthukisa amandla ayo okuqina.Lokhu kufezwa ngokwakhiwa kwenethiwekhi enezinhlangothi ezintathu zama-molecule e-starch ether enhlanganisweni, esebenza njengokuqinisa futhi esiza ukusabalalisa izingcindezi eziqinile ngokulinganayo.Lokhu kungathuthukisa ukuqina okuphelele nokuhlala isikhathi eside komkhiqizo osekelwe kusimende.

Kafushane, ukusetshenziswa kwe-starch ether emikhiqizweni esekwe usimende kungathuthukisa ukusebenza kwayo, ukugcinwa kwamanzi, ukunamathela, kanye nezakhiwo zokumelana nokuqhekeka.I-starch ether ifinyelela lokhu ngokunciphisa i-viscosity yengxube, yenza ifilimu evikelayo ezungeze izinhlayiya zikasimende, ikhulise ukuqina kwengxube, futhi ithuthukise amandla okuqina omkhiqizo.Ukusetshenziswa kwe-starch ether emikhiqizweni esekwe kusimende kungathuthukisa ukusebenza okuphelele nokuqina kwengxube, okuholela kunqubo yokwakha esebenza kahle futhi ephumelelayo.
