Bambanci tsakanin HPMC vs methylcellulose

HPMC (Hydroxypropyl methylcellulose) da methylcellulose duka ana amfani da su a cikin abinci, magunguna, da masana'antar kulawa ta sirri azaman masu kauri, masu ƙarfi, emulsifiers, da wakilai masu ɗaure. Yayin da suke raba wasu kamanceceniya, akwai wasu bambance-bambance tsakanin HPMC da methylcellulose:

1. Tsarin sinadaran: Dukansu HPMC da methylcellulose an samo su ne daga cellulose, polysaccharide da ke faruwa ta halitta. HPMC shine cellulose da aka gyara, inda aka maye gurbin wasu ƙungiyoyin hydroxyl akan kwayoyin halitta na cellulose da ƙungiyoyin hydroxypropyl. Methylcellulose kuma shine cellulose da aka gyara, inda aka maye gurbin wasu ƙungiyoyin hydroxyl akan kwayoyin cellulose da ƙungiyoyin methyl.
2. Solubility: HPMC ya fi soluble a cikin ruwa fiye da methylcellulose, wanda ya sa ya fi sauƙi narke da amfani da shi a cikin tsari.
3. Danko: HPMC yana da danko mafi girma fiye da methylcellulose, wanda ke nufin yana da mafi kyawun kaddarorin kauri kuma yana iya haifar da daidaito mai kauri a cikin abubuwan da aka tsara.
4. Gelation: Methylcellulose yana da ikon samar da gel lokacin zafi sannan kuma a sanyaya, yayin da HPMC ba shi da wannan kayan.
5. Farashin: HPMC gabaɗaya ya fi methylcellulose tsada.

Gabaɗaya, zaɓi tsakanin HPMC da methylcellulose zai dogara ne akan takamaiman aikace-aikacen da kaddarorin da ake so na ƙirar. Ana iya fifita HPMC don narkewar sa da daidaito mai kauri, yayin da methylcellulose na iya fi son ikonsa na samar da gels.
