Menene maki daban-daban na HPMC?

HPMC, ko hydroxypropyl methylcellulose, wani nau'i ne na asalin cellulose wanda aka saba amfani dashi azaman wakili mai kauri, emulsifier, da stabilizer a cikin samfura iri-iri. Fari ne mara wari mara dandano wanda ake narkewa a cikin ruwan sanyi kuma ba a iya narkewa a cikin ruwan zafi.

Ana samun HPMC a nau'o'in maki iri-iri, kowanne yana da kayan aikinsa na musamman da aikace-aikace. Makin HPMC sun dogara ne akan matakin maye gurbin (DS) na ƙungiyoyin hydroxypropyl, wanda shine ma'auni na adadin ƙungiyoyin hydroxypropyl a kowace naúrar anhydroglucose. Mafi girman DS, yawancin ƙungiyoyin hydroxypropyl suna nan kuma mafi yawan hydrophilic HPMC shine.

An raba maki na HPMC zuwa manyan rukunai guda uku: ƙananan DS, matsakaici DS, da babban DS.

Ana amfani da ƙananan DS HPMC a aikace-aikace inda ake buƙatar ƙarancin danko da ƙarancin gel. Ana amfani da wannan darajar sau da yawa a cikin aikace-aikacen abinci da abin sha, kamar ice cream, biredi, da gravies. Hakanan ana amfani dashi a aikace-aikacen magunguna, kamar allunan da capsules.

Ana amfani da matsakaicin DS HPMC a aikace-aikace inda ake son ƙarin danko da ƙarfin gel. Ana yawan amfani da wannan maki a cikin aikace-aikacen abinci da abin sha, kamar jams da jelly, da kuma a aikace-aikacen magunguna, kamar man shafawa da man shafawa.

Ana amfani da High DS HPMC a aikace-aikace inda ake son babban danko da ƙarfin gel. Ana amfani da wannan matakin sau da yawa a cikin aikace-aikacen abinci da abin sha, kamar cuku da yogurt, da kuma a aikace-aikacen magunguna, kamar suppositories da pessaries.

Baya ga manyan nau'ikan nau'ikan HPMC guda uku, akwai kuma rukuni-rukuni da yawa. Waɗannan rukunoni sun dogara ne akan matakin maye gurbin, girman barbashi, da nau'in ƙungiyar hydroxypropyl.

Matsakaicin juzu'in maye gurbin sun dogara ne akan matakin maye gurbin ƙungiyoyin hydroxypropyl. Waɗannan rukunin ƙananan ƙananan DS ne (0.5-1.5), matsakaici DS (1.5-2.5), da kuma DS masu girma (2.5-3.5).

Rukunin girman girman barbashi sun dogara ne akan girman ɓangarorin. Waɗannan ƙananan rukunoni suna da kyau (ƙasa da microns 10), matsakaici (10-20 microns), da ƙaƙƙarfan (fiye da 20 microns).

Nau'in rukunin ƙungiyoyin hydroxypropyl sun dogara ne akan nau'in ƙungiyar hydroxypropyl da ke cikin HPMC. Waɗannan ƙananan rukunin sune hydroxypropyl methylcellulose (HPMC), hydroxypropyl ethylcellulose (HPEC), da hydroxypropyl cellulose (HPC).

HPMC wani sinadari ne mai iya aiki da shi sosai a cikin samfura iri-iri. Daban-daban maki na HPMC sun dogara ne a kan matakin maye gurbin, girman barbashi, da nau'in rukunin hydroxypropyl, kuma kowane aji yana da nasa musamman kaddarorin da aikace-aikace.
