Menene Abubuwan Sinadarai na Hypromellose?

Hydroxypropyl Methylcellulose (HPMC), kuma aka sani da Hypromellose, polymer roba ce da aka samu daga cellulose. Abubuwan sinadaransa sun haɗa da:

1. Solubility: HPMC yana narkewa cikin ruwa kuma yana samar da ingantaccen bayani idan an gauraye shi da ruwa. Solubility na HPMC ya dogara da matakin maye gurbinsa (DS) da darajar danko.
2. Dankowa: Ana samun HPMC a cikin nau'o'in danko daban-daban, kama daga ƙasa zuwa babban danko. Dankowar HPMC ya dogara da nauyin kwayoyin sa, matakin maye gurbinsa, da maida hankali.
3. Kwanciyar hankali: HPMC yana da ƙarfi a ƙarƙashin yanayin al'ada na zazzabi da pH. Yana da juriya ga lalata ƙwayoyin cuta kuma baya rubewa cikin sauƙi.
4. Abubuwan thermal: HPMC yana da kwanciyar hankali mai kyau kuma yana iya jure yanayin zafi har zuwa 200 ° C ba tare da rubewa ba.
5. Ayyukan sararin sama: HPMC yana da aikin saman saboda yanayin polar sa, wanda ya sa ya zama mai amfani azaman mai watsawa da emulsifier a aikace-aikace daban-daban.
6. Hygroscopicity: HPMC hygroscopic ne, ma'ana yana da halin sha danshi daga muhalli. Wannan kadarorin yana sa ya zama mai amfani azaman wakili mai riƙe ruwa a aikace-aikace daban-daban.
7. Sinadarin sake kunnawa: HPMC ba ta da ƙarfi kuma baya aiki da wasu sinadarai. Duk da haka, yana iya samar da haɗin gwiwar hydrogen tare da wasu kwayoyin polar, wanda ya sa ya zama mai amfani a matsayin mai kauri, mai ɗaure, da tsohon fim a aikace-aikace daban-daban.

A takaice,HPMCyana da kaddarorin sinadarai da yawa waɗanda suka mai da shi polymer mai amfani da yawa a masana'antu daban-daban, gami da magunguna, abinci, kayan kwalliya, da gini. Solubility, danko, kwanciyar hankali, thermal Properties, surface aiki, hygroscopicity, da sinadaran reactivity sa shi dace da fadi da kewayon aikace-aikace.
