Hydroxethyl Cellulose (HEC) ichinyima mvura pamusoro pehuremu hwakajeka idzo dzine methyl cellulose celler Kuti uisezve chikonzero chekushamisika kwakanyanya kwehyoko, kudzikisira kwemvura kwechiitiko.
Muchidzidzo ichi, her samples yakaongororwa nhamba yeMalol yeHydroxyl Substitutions (MS) yeGlucose Pyran unit kubva pa1.3 kusvika 3.6 kusvika 3.6. Zvese Hec Sampuli dzakanyungudika mumvura mukati meiyo tembiricha yakaongororwa uye yakaratidza kuti hapana turbidity mapoinzi. Iyo NH Kukosha kweHEC samples ine ms 1,3 ndeye 14 pa 20 ° C, uye inoderera zvishoma nezvishoma ne tembiricha ichikwira, uye inodonhedza kusvika pagumi kusvika pamakumi manomwe kusvika 70 ° C. Iyo PH Kukosha kweHEC sampuli iri pachena yakakura kupfuura iyo shoma yekukoshesesa nh kukosha kwe approx. 5 Cellulose etile ana mc uye hpmc inofanira kunyungudutswa mumvura, kunyangwe mune yakanyanya kupisa.
Hec mamorekuru, zvisinei, anokanda mvura-inoyerera pamusoro pekudziya kwakakura. Iyo tembiricha yakatsvuka yeNH yeHec samples uye triglycol (modhi mishonga yehec stils) ndeyenyama uye yakafanana neyavo.
