1. Kupisa kwejeli (0.2% mhinduro) 50-90°C.
2. Inonyungudika mumvura uye yakawanda polar c uye chikamu chakakodzera cheethanol/mvura, propanol/mvura, dichloroethane, nezvimwewo, isinganyungudike mu ether, acetone, absolute ethanol, uye inokura kuita clear kana turbid zvishoma mumvura inotonhora colloidal solution. Mvura ine activity pamusoro, yakajeka uye inoshanda zvakatsiga.
3. HPMC ine hunhu hwekupisa. Mvura inogadzirwa nechinhu ichi inopiswa kuti igadzire gel uye inonaya, yozonyunguduka mushure mekutonhora. Tembiricha yekupisa yemhando dzakasiyana inosiyana. Kunyunguduka kunosiyana zvichienderana nekunyunguduka. Kunyunguduka kushoma, ndiko kunyunguduka kukuru. Mhando dzakasiyana dzeHPMC dzine musiyano muhunhu hwadzo, uye kunyunguduka kweHPMC mumvura hakukanganisike ne pH value.
4. Saizi yezvikamu: 100 mesh pass rate yakakura kupfuura 98.5%. Kuwanda kwehuwandu: 0.25-0.70g/ (kazhinji inenge 0.4g/), dhiravhiti chaiyo 1.26-1.31. Tembiricha yekuchinja ruvara: 180-200°C, tembiricha yecarbonization: 280-300°C. Kukosha kwemethoxyl kunobva pa19.0% kusvika 30.0%, uye kukosha kwehydroxypropyl kunobva pa4% kusvika 12%. Viscosity (22°C, 2%) 5～200000mPa .s. Tembiricha yeGel (0.2%) 50-90°C
5. HPMC ine hunhu hwekukwanisa kukora, kuburitsa munyu, kugadzikana kwePH, kuchengetedza mvura, kugadzikana kwemativi, hunhu hwakanaka hwekugadzira firimu, kusimba kwema enzyme akasiyana-siyana, kupararira uye kubatana.
