Izici zomkhiqizo we-hydroxypropyl methylcellulose yokwakha

I-Soluble emanzini kanye nezinye izincibilikisi eziphilayo zingancibilika emanzini abandayo, ukugxila kwayo okuphezulu kunqunywa kuphela i-viscosity, ukuncibilika kuyashintsha nge-viscosity, i-viscosity ephansi, i-solubility enkulu.

Ukumelana nosawoti: I-Hydroxypropyl methylcellulose yokwakha i-ether ye-cellulose engeyona i-ionic futhi ayiyona i-polyelectrolyte, ngakho-ke izinzile kusisombululo samanzi lapho usawoti wensimbi noma ama-electrolyte ephilayo ekhona, kodwa ukwengezwa ngokweqile kwama-electrolyte kungabangela ukujiya kweGlue kanye nemvula.

Umsebenzi ongaphezulu: ngenxa yomsebenzi osebenzayo ongaphezulu wesisombululo esinamanzi, singasetshenziswa njenge-ejenti yokuvikela ye-colloidal, i-emulsifier ne-dispersant.

Lapho ishiselwa ezingeni elithile lokushisa, isixazululo esinamanzi se-hydroxypropyl methylcellulose sesakhiwo sejeli esishisayo siba yi-opaque, ama-gel, kanye nemvula, kodwa lapho sipholiswa ngokuqhubekayo, sibuyela esimweni sokuqala sesisombululo, futhi lokhu kufiphala kwenzeka. Izinga lokushisa leglue kanye nemvula ikakhulukazi lincike ezintweni zokugcoba, ama-agent amisiwe, ama-colloid avikelayo, ama-emulsifiers, njll.

Izici Zomkhiqizo

I-Anti-mildew: Inekhono elihle lokunqanda isikhutha 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 Ngenxa yokuthi isixazululo esinamanzi esigxile kakhulu se-hydroxypropyl methylcellulose yokwakha sinezakhiwo ezikhethekile ze-viscoelastic uma kuqhathaniswa nezixazululo ezinamanzi zamanye ama-polymers, ukungezwa kwaso kungathuthukisa ikhono lokulondoloza ukwakheka kwemikhiqizo ye-ceramic ekhishwe.

Ukugcinwa kwamanzi: i-hydroxypropyl methylcellulose yokwakha ine-hydrophilicity kanye ne-viscosity ephezulu yesisombululo sayo esinamanzi, okuyi-ejenti yokugcina amanzi esebenza kahle kakhulu.

Ezinye izakhiwo: i-thickener, i-ejenti eyenza ifilimu, i-binder, i-lubricant, i-ejenti yokumisa okwesikhashana, i-colloid evikelayo, i-emulsifier, njll.
