Inogona hpmc uye cmc musanganiswa
Methyl cellulosechena kana chena kunge fibrous kana granular poda; Isina kusimba, isina kunaka. Ichi chigadzirwa mumvura kuzvimba kwemvura mune yakajeka kana zvishoma turbid colodal solution; Insoluble muMhedziso ethanol, chloroform kana dietthyl ether. Yakakurumidza kuparadzirwa uye yakazvimba mumvura inopisa pa80-90 ℃, uye nekukurumidza yakadzikira mushure mekutonhora. Mhinduro yemvura yakagadzikana kwazvo pamhepo tembiricha, uye inogona kuseka tembiricha yakakwira, uye iyo gel inogona kuchinja nemhinduro nekushisa.
Iyo ine yakanyanya kunyorova, kupararira, kuderedza, kurerutsa, kudzvanywa, kudzokorora kwemvura uye kuumbwa kwefirimu, pamwe nekukanyiwa kwemafuta. Iyo firimu ine kunaka kwakanyanya, kuchinjika uye kujeka. Nekuti is is is is-ionic, inogona kuwirirana nemunyu, uye mhinduro yakagadzikana muhuwandu hwePH2 - 12. Sodium carboxy iyi chigadzirwa ndiyo sodium munyu we cellulose carboxymeyment, NdezveAnanic Cellalose ether, chena kana Milky White Fibrouts poda kana Chikamu, density 0.5-0 G / Cubic Centraimeter, Cubic Asina kukwana, isina kana hygrapic. Easy kuparadzira mumvura mumvura inojekesa emagetsi emagetsi, isingaenzaniswi mu ethanol uye mamwe organic sol.
Kana iyo pH yemhinduro mhinduro ndeye 6.5 - 8.5, viscosity yekutsvedza inodyira zvakanyanya kana pH iri> 10, uye kugadzirwa kwakanaka kana kugadzikana kwekunzwa, iyo viscosity inosimuka nekukurumidza pazasi 20 ℃, inoshanduka zvishoma pa45 ℃, uye iyo colloid Denaturation uye viscosity uye zvivakwa zvinodzikira zvakanyanya kana ichipiswa kwenguva yakareba kupfuura 80 ℃. Zvinyoro-nyoro mumvura, mhinduro inoonekera; Iyo yakagadzikana kwazvo muAlkaline Solution, uye nyore kuHydrolyze mune iyo acid. Kana iyo PH kukosha iri 2-3, kunyorova kuchaitika, uye kunyorova kuchaitika zvakare mune yakakwana yesimbi simbi. HydroxyPropyl methyl methyl cellelose, zvakare seydroxyprusyl metdroxproproproproproproproproproproclose cellyl
Kunyudzwa mumvura uye yakawanda polar c uye yakakodzera chikamu che ethanol / mvura, mvura, inokanganisa mumvura inotonhora mune yakajeka kana zvishoma turbided courlidal solution. Iyo mhinduro yemvura ine nzvimbo yemusoro, yakakwira transparency uye yakagadzikana kuita.Hpcine nzvimbo yeiyo inopisa gel. Mushure mekupiswa, iyo yekugadzirisa mhedzisiro mhinduro inoumba maGel chairo, uye wozonyungudika mushure mekutonhora. Tembiricha yegwenzi redzidziso dzakasiyana dzakasiyana.
