IHydroxypropyl methyl cellulose ether yokwakha

Izici zomkhiqizo we-hydroxypropyl methylcellulose yokwakha

Incibilika emanzini nakwezinye izincibilikisi eziphilayo. Ingancibilika emanzini abandayo. Ukugxila kwayo okuphezulu kuncike kuphela ku-viscosity. I-solubility iyashintsha nge-viscosity. I-viscosity ephansi, i-solubility enkulu.

I-hydroxypropyl methylcellulose ethile engamelana nosawoti iyi-ether engeyona ionic cellulose, futhi ayiyona i-polyelectrolyte, ngakho-ke izinzile kusisombululo samanzi lapho kukhona usawoti wensimbi noma ama-electrolyte aphilayo, kodwa ukwengezwa ngokweqile kwama-electrolyte kungabangela ukugeleza kwemvula kanye nemvula. .

Umsebenzi ongaphezulu Ngenxa yokuthi isixazululo esinamanzi sinomsebenzi ongaphezulu, singasetshenziswa njengesivikelo se-colloidal, i-emulsifier ne-dispersant. Lapho isixazululo esinamanzi se-hydroxypropyl methylcellulose yokwakha sishiselwa ezingeni lokushisa elithile, siba yi-opaque, ama-gel, kanye nemvula, kodwa lapho sipholile ngokuqhubekayo, sibuyela esimweni sokuqala sesixazululo, futhi le jeli kanye nemvula kwenzeka. kumafutha abo, ama-agent amisiwe, ama-colloid okuzivikela, ama-emulsifiers, njll.

Ukumelana nesikhutha Inekhono elihle lokulwa nesikhutha kanye nokuzinza okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside.

Ukuzinza kwe-PH, i-viscosity ye-hydroxypropyl methylcellulose isixazululo samanzi sokwakha ayithintwa neze i-asidi noma i-alkali, futhi inani le-pH alizinzile kububanzi obungu-3.0 ukuya ku-11.0.

Ukugcinwa komumo Njengoba isixazululo esinamanzi esigxile kakhulu se-hydroxypropyl methylcellulose yokwakha sinezakhiwo ezikhethekile ze-viscoelastic uma kuqhathaniswa nezixazululo ezinamanzi zamanye ama-polymers, ukungezwa kwaso kungathuthukisa ikhono lokugcina ukuma kwemikhiqizo ye-ceramic ekhishwe.

Ukugcinwa kwamanzi I-Hydroxypropyl methylcellulose yokwakha iwuhlobo lwe-ejenti yokugcina amanzi esebenza kahle kakhulu ngenxa ye-hydrophilicity yayo ephezulu kanye ne-viscosity ephezulu yesisombululo sayo esinamanzi. Ezinye izakhiwo I-Thickener, i-ejenti eyenza ifilimu, i-binder, i-lubricant, i-ejenti elengayo, i-colloid evikelayo, i-emulsifier, njll.
