Menene hydroxyethyl methyl cellulose (HEMC)?

 Hydroxyethyl methylcellulose(HEMCkuma an san shi da methylhydroxyethyl cellulose (MHEC). Fari ne, fari mai launin toka, ko fari mai rawaya.

Halayen HEMC

HEMCyana da ayyuka daban-daban. Sun hada da:

1. Bayyanar

 HEMCzai iya zama fari, rawaya mai haske, farar rawaya, ko fari mai launin toka.

2. Solubility

HEMCyana narkewa cikin ruwa (sanyi ko zafi). Ko da yakeHEMCba a iya narkewa a cikin mafi yawan kaushi na halitta, yana narkewa a cikin kaushi na kwayoyin halitta da tsarin ruwa mai narkewa.

Babban maida hankalinsa ya dogara da danko, kuma solubility ya bambanta da danko. Ƙananan danko, mafi girma da solubility, kuma akasin haka.

3. Zaman lafiyar pH

 HEMCyana da tsayayye a cikin kewayon 3.0-11.0 kuma dankowar sa kusan ba ya shafa, amma wuce wannan kewayon zai rage danko.

4. Metabolism

 HEMCwani sinadari ne da ba ya da kuzari wanda ake amfani da shi sosai a abinci da magunguna saboda rashin iya jurewa metabolism.

5. Ayyukan saman

Saboda aikin da yake aiki a saman a cikin mafita mai ruwa, ana iya amfani dashi azaman mai watsawa, mai karewa, da emulsifier.

6. Juriya na naman gwari

A cikin dogon lokaci ajiya,HEMCyana da kyau danko kwanciyar hankali, saboda haka yana da kyau mold juriya.

Its anti mold ikon ya fi na hydroxyethyl cellulose.

7. Riƙe ruwa

 HEMCya zama wakili mai tasiri mai tasiri na ruwa saboda yawan danko a cikin maganin ruwa.

Ƙarfin ajiyar ruwa ya fi na methyl cellulose girma.

8. Toka abun ciki
