Isiphi isici se-viscosity sesisombululo samanzi se-hydroxypropyl methyl cellulose?
I-Hydroxypropyl methyl cellulose inethuba elibanzi embonini yezokwakha, futhi izakhiwo zayo ezinhle kakhulu zokujiya nokugcina amanzi zenza ukusetshenziswa kwayo embonini yezokwakha kunganakwa.Kodwa kungakanani esikwaziyo ngobuhle bayo?Manje ake sikhulume ngezakhiwo ze-viscosity ze-hydroxypropyl methyl cellulose isixazululo samanzi.
I-Hydroxypropyl methyl cellulose isixazululo esimanzi isingeniso esilula: Isifinyezo sesiNgisi esithi HPMC non-ionic, i-cellulose ether encibilikayo emanzini, ukubukeka kwempushana emhlophe noma ekhanyayo ephuzi noma impahla eyimbudumbudu.Amakhemikhali awo angenakunambitheka, angenaphunga, angenabuthi, futhi azinzile omkhiqizo emanzini ukuze akhe uketshezi lwe-viscous olubushelelezi olubonakala kancane.
Yiziphi izici ezithinta i-viscosity yesisombululo samanzi se-hydroxypropyl methyl cellulose?
1.Ubudlelwano ne-polymer: i-viscosity ye-hydroxypropyl methyl cellulose isixazululo samanzi ilingana ne-polymer noma isisindo samangqamuzana, futhi iyanda ngokuthuthuka kwe-polymerization degree.Lo mphumela usobala kakhulu esimweni se-polymerization ephansi kunesimo se-polymerization ephezulu.
2.Ubudlelwano phakathi kwe-viscosity nokugxilisa ingqondo: i-viscosity ye-hydroxypropyl methyl cellulose kusisombululo samanzi iyanda ngokugxila kwesisombululo esinamanzi, futhi ngisho noshintsho oluncane lokuhlushwa lungabangela ushintsho olukhulu ku-viscosity.
3.Ubudlelwano phakathi kwe-viscosity ne-shear rate: Ukuhlola kubonisa ukuthi i-hydroxypropyl methyl cellulose ayinalo ushintsho olubalulekile ngezinga eliphansi lokugunda, futhi i-viscosity iyancipha ngokunyuka kwezinga lokugunda.
4.Ubudlelwano phakathi kwe-viscosity nezinga lokushisa: i-hydroxypropyl methyl cellulose ithintwa kakhulu izinga lokushisa, futhi i-viscosity iyancipha ngokunyuka kwezinga lokushisa.
5.Ezinye izici: i-viscosity ye-hydroxypropyl methyl cellulose kanye nezithasiselo ezihlukahlukene, izixazululo, amanani we-PH nawo anomthelela.
Uma senza into yokuhlolwa kwelebhu okudingeka siyazi mayelana nesici se-viscosity ye-hydroxypropyl methyl cellulose isixazululo samanzi?
