HPMC INGREDIENT
Hydroxypropyl Methylcellulose (HPMC) shine ether cellulose wanda aka samo daga cellulose na halitta, da farko itace ko auduga, ta hanyar tsarin sinadarai. Ga bayyani na sinadarai da kaddarorin HPMC:
- Cellulose: Cellulose shine babban sinadari a cikin HPMC. Polysaccharide ne da ke faruwa a zahiri wanda ya ƙunshi maimaita raka'o'in glucose da aka haɗa tare cikin dogayen sarƙoƙi. Cellulose yana aiki azaman kashin bayan HPMC kuma yana ba da daidaiton tsari.
- Methylation: Kashin baya na cellulose yana canzawa ta hanyar sinadarai ta hanyar tsarin da ake kira methylation, inda ake amsa methyl chloride tare da cellulose a gaban alkali don gabatar da ƙungiyoyin methyl (-CH3) akan sarkar cellulose. Wannan tsari na methylation yana da mahimmanci don haɓaka solubility na ruwa da sauran kaddarorin cellulose.
- Hydroxypropylation: Bugu da ƙari ga methylation, ƙungiyoyin hydroxypropyl (-CH2CHOHCH3) kuma za a iya gabatar da su akan sarkar cellulose ta hanyar hydroxypropylation. Wannan yana ƙara canza kaddarorin cellulose, inganta riƙe ruwa, ikon yin fim, da sauran halaye.
- Etherification: Gabatarwar ƙungiyoyin methyl da hydroxypropyl akan sarkar cellulose ana kiranta etherification. Etherification yana canza tsarin sinadarai na cellulose, yana haifar da samuwar HPMC tare da kaddarorin musamman masu dacewa da aikace-aikace daban-daban.
- Abubuwan Jiki: HPMC yawanci fari ne zuwa fari, mara wari, da foda mara ɗanɗano. Yana da narkewa a cikin ruwan sanyi kuma yana samar da mafita mai tsabta ko ɗan turbid dangane da maida hankali da matsayi. HPMC yana nuna kyakkyawan riƙewar ruwa, kauri, ƙirƙirar fim, da kaddarorin ayyuka na saman, yana mai da shi mahimmanci a cikin masana'antu da yawa, gami da gini, magunguna, abinci, da kayan kwalliya.
Gabaɗaya, manyan abubuwan da ke cikin HPMC sune cellulose, methyl chloride (na methylation), da propylene oxide (na hydroxypropylation), tare da masu haɓaka alkali da sauran abubuwan da ake amfani da su a cikin tsarin masana'antu. Waɗannan sinadarai suna fuskantar halayen sinadarai don samar da HPMC tare da ƙayyadaddun kaddarorin da aka keɓe don biyan buƙatun aikace-aikace daban-daban.
