Hydroxypropyl methylcellulose, 28-30% methoxyl, 7-12% hydroxypropyl
Takaddun bayanai "28-30% methoxyl" da "7-12% hydroxypropyl" suna nufin matakin maye gurbin.Hydroxypropyl Methylcellulose(HPMC). Waɗannan dabi'u suna nuna iyakar abin da aka gyara sinadarai na asali na cellulose tare da ƙungiyoyin methoxyl da hydroxypropyl.
- 28-30% Methoxyl:
- Wannan yana nuna cewa, a matsakaita, 28-30% na asali na ƙungiyoyin hydroxyl a kan kwayoyin cellulose an maye gurbinsu da ƙungiyoyin metoxyl. An gabatar da ƙungiyoyin methoxyl (-OCH3) don ƙara yawan hydrophobicity na polymer.
- 7-12% Hydroxypropyl:
- Wannan yana nuna cewa, a matsakaita, kashi 7-12% na asalin ƙungiyoyin hydroxyl a kan ƙwayoyin cellulose an maye gurbinsu da ƙungiyoyin hydroxypropyl. Ƙungiyoyin Hydroxypropyl (-OCH2CHOHCH3) an gabatar da su don haɓaka solubility na ruwa da kuma gyara wasu kayan jiki da sinadarai na polymer.
Matsayin maye gurbin yana rinjayar kaddarorin HPMC da aikinsa a aikace-aikace daban-daban. Misali:
- Babban abun ciki na methoxyl gabaɗaya yana ƙara haɓakar hydrophobicity na polymer, yana shafar narkewar ruwa da sauran kaddarorinsa.
- Babban abun ciki na hydroxypropyl na iya haɓaka solubility na ruwa da abubuwan ƙirƙirar fim na HPMC.
Waɗannan ƙayyadaddun bayanai suna da mahimmanci wajen daidaita HPMC don biyan takamaiman buƙatu a masana'antu daban-daban. Misali, a cikin masana'antar harhada magunguna, zaɓin darajar HPMC tare da takamaiman digiri na canji na iya shafar bayanan bayanan sakin ƙwayoyi a cikin ƙirar kwamfutar hannu. A cikin masana'antar gine-gine, zai iya tasiri tasirin riƙewar ruwa da abubuwan mannewa na samfuran tushen ciminti.
Masana'antun suna samar da nau'o'i daban-daban na HPMC tare da digiri daban-daban na maye gurbin don biyan buƙatun daban-daban na aikace-aikace daban-daban. Lokacin amfani da HPMC a cikin ƙira, yana da mahimmanci ga masu ƙira suyi la'akari da takamaiman matakin HPMC wanda ya dace da kaddarorin da ake so da halayen aiki don aikace-aikacen da aka yi niyya.
