Mamorekuru: C2H6O2 xCH4O x PhEur 2002 anotsanangura hydroxyethylmethylcellulose se cellulose ine chikamu cheO-methylated, chikamu cheO-hydroxymethylated. Tsanangudzo dzakasiyana dzinoratidzwa maererano nekuoneka kwe viscosity mu mPas ye 2% w/v aqueous solution pa20°C.
Kurema kwemamorekuru: PhEur 2002 inotsanangura hydroxyethylmethylcellulose se cellulose ine chikamu cheO-methylated, chikamu cheO-hydroxymethylated. Tsanangudzo dzakasiyana dzinoratidzwa maererano nekuoneka kwe viscosity mu mPas ye 2% w/v aqueous solution pa 20°C.

Hunhu hukuru hwehydroxyethyl methyl cellulose (HEMC) ndehwekuti:

1. Kunyungudika: inonyungudika mumvura uye mune zvimwe zvinonyungudika zve organic, HEMC inogona kunyungudika mumvura inotonhora, huwandu hwayo hwepamusoro hunongoonekwa nekunyungudika, kunyungudika kunosiyana nekunyungudika, kunyungudika kwakaderera, kunyungudika kukuru.

2. Kusagona munyu: Zvigadzirwa zveHEMC hazvina maether e-cellulose uye hazvisi mapolyelectrolyte, saka kana paine munyu wesimbi kana ma electrolyte eorganic, zvinogadzikana mumvura, asi kuwedzera ma electrolyte zvakanyanya kunogona kukonzera gelation uye kunaya kwemvura.

3. Kushanda pamusoro: Sezvo mvura ine basa rekushanda pamusoro, inogona kushandiswa semushonga unodzivirira colloid, emulsifier uye dispersant.

4. Thermal gel: Kana mhinduro yemvura yeHEMC chigadzirwa ichipiswa kusvika patembiricha yakati, inova isina kujeka, majeli, uye inoita precipitate, asi kana ichitonhodzwa nguva dzose, inodzokera kumamiriro ekutanga emhinduro, uye gel iyi nemvura zvinoitika. Tembiricha yacho inonyanya kutsamira pamafuta ayo, zvinobatsira pakumisa, macolloid ekudzivirira, emulsifiers, nezvimwewo.

5. Kusashanda zvakanaka kwemetabolism uye kunhuhwirira kushoma uye kunhuhwirira: HEMC inoshandiswa zvakanyanya mukudya nemumishonga nekuti haina kugayiwa uye ine kunhuhwirira kushoma uye kunhuhwirira kushoma.

6. Mushonga wekuuraya fungus: HEMC ine kugona kwakanaka kwekuuraya fungus uye kugara zvakanaka kweganda panguva yekuchengetwa kwenguva refu.

7. Kugadzikana kwePH: Kusimba kweHEMCMvura inobuda muchigadzirwa hainyanyi kukanganiswa neasidhi kana alkali, uye pH yakagadzikana pakati pe3.0-11.0.

Mashandisirwo: Hydroxyethyl methyl cellulose inogona kushandiswa semushonga unodzivirira colloid, emulsifier uye dispersant nekuda kwebasa remvura rinoita pamusoro pemvura. Muenzaniso wekushandiswa kwayo ndewekuti: Mhedzisiro yehydroxyethyl methyl cellulose pahunhu hwesimende. Hydroxyethyl methylcellulose ipfu chena isina hwema, isina kunaka, isina chepfu inonyunguduka mumvura inotonhora kuti igadzire mhinduro yakajeka, ine viscous. Ine hunhu hwekukora, kusunga, kuparadzira, emulsifying, kugadzira firimu, kumisa, kunyudza, gelling, surface-active, kuchengetedza hunyoro uye kuchengetedza colloids. Nekuda kwebasa remvura rinoita pamusoro pemvura, inogona kushandiswa semushonga unodzivirira colloid, emulsifier uye dispersant. Hydroxyethyl methyl cellulose aqueous solution ine hydrophilicity yakanaka uye inoshanda zvakanyanya kuchengetedza mvura.
