Focus on Cellulose ethers

Hydroxyethyl methyl cellulose zvivakwa

Chikamu 11 (1-6)

01
Solubility:
Inonyungudika mumvura uye mamwe organic solvents. Inogona kunyungudutswa mumvura inotonhora. Kunyanya kusungirirwa kwayo kunongogadziriswa ne viscosity. Iyo solubility inoshanduka ne viscosity. Iyo yakaderera viscosity, iyo yakakura solubility.

02
Kuramba munyu:
Chigadzirwa chacho i-non-ionic cellulose ether uye haisi polyelectrolyte, saka inenge yakagadzikana mumushonga wemvura muhupo hwesimbi yemunyu kana organic electrolytes, asi kuwedzera kwakanyanya kwe electrolytes kunogona kukonzera gelation uye kunaya kwemvura.

03
Chiitiko chepamusoro:
Nekuda kweiyo yepamusoro inoshanda basa reiyo aqueous solution, inogona kushandiswa se colloid inodzivirira agent, emulsifier uye dispersant.

04
Thermal Gel:
Kana chigadzirwa chine aqueous solution chikapiswa kune imwe tembiricha, chinova opaque, gels, uye kuita mvura, asi kana chikaramba chichitonhodzwa, chinodzokera kune yekutanga mhinduro mamiriro, uye tembiricha iyo iyo gelation uye kunaya kwemvura kunoitika zvakanyanya zvinoenderana. pamafuta avo. , kumisa rubatsiro, inodzivirira colloid, emulsifier, nezvimwe.

05
metabolism:
Metabolically inert uye yakaderera kunhuhwirira uye kunhuhwirira, ivo vanoshandiswa zvakanyanya mukudya nemushonga nekuti ivo havana metabolized uye vane kunhuhwirira kwakaderera uye hwema.

06
Meldew resistance:
Iyo ine yakanaka antifungal kugona uye yakanaka viscosity kugadzikana panguva yekuchengetedza kwenguva refu.
