Kodi magiredi osiyanasiyana a HPMC ndi ati?

HPMC, kapena hydroxypropyl methylcellulose, ndi mtundu wa cellulose yochokera kuzinthu zomwe zimagwiritsidwa ntchito ngati thickening agent, emulsifier, ndi stabilizer muzinthu zosiyanasiyana. Ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umasungunuka m'madzi ozizira komanso osasungunuka m'madzi otentha.

HPMC imapezeka m'makalasi osiyanasiyana, iliyonse ili ndi katundu wake ndi ntchito zake. Magiredi a HPMC amachokera ku degree of substitution (DS) yamagulu a hydroxypropyl, womwe ndi muyeso wamagulu a hydroxypropyl pa unit anhydroglucose. DS ikakwera, magulu a hydroxypropyl amakhalapo ndipo HPMC imakhala ya hydrophilic.

Makalasi a HPMC agawidwa m'magulu atatu: otsika DS, sing'anga DS, ndi DS wapamwamba.

Low DS HPMC amagwiritsidwa ntchito m'mapulogalamu omwe amafunikira kukhuthala kochepa komanso mphamvu ya gel otsika. Gululi limagwiritsidwa ntchito nthawi zambiri pazakudya ndi zakumwa, monga ayisikilimu, sauces, ndi gravies. Amagwiritsidwanso ntchito pazamankhwala, monga mapiritsi ndi makapisozi.

Medium DS HPMC imagwiritsidwa ntchito pamapulogalamu omwe amafunidwa kukhuthala kwakukulu ndi mphamvu ya gel. Gululi limagwiritsidwa ntchito nthawi zambiri pazakudya ndi zakumwa, monga jamu ndi ma jellies, komanso pazamankhwala, monga mafuta odzola ndi zonona.

High DS HPMC imagwiritsidwa ntchito pamapulogalamu omwe amafunidwa kukhuthala kwambiri komanso mphamvu ya gel. Gululi nthawi zambiri limagwiritsidwa ntchito pazakudya ndi zakumwa, monga tchizi ndi yogati, komanso pazamankhwala, monga ma suppositories ndi pessaries.

Kuphatikiza pa magulu atatu akuluakulu a HPMC, palinso magawo angapo. Ma subcategories awa amatengera kuchuluka kwa m'malo, kukula kwa tinthu, ndi mtundu wa gulu la hydroxypropyl.

Kuchuluka kwa magawo olowa m'malo kumatengera kuchuluka kwa m'malo mwa magulu a hydroxypropyl. Magawo awa ndi otsika DS (0.5-1.5), sing'anga DS (1.5-2.5), ndi DS wapamwamba (2.5-3.5).

The tinthu kukula subcategories zachokera kukula kwa particles. Magawo ang'onoang'ono awa ndi abwino (osakwana ma microns 10), sing'anga (10-20 microns), ndi coarse (ma microns 20).

Mtundu wamagulu amagulu a hydroxypropyl amatengera mtundu wa gulu la hydroxypropyl lomwe lili mu HPMC. Maguluwa ndi hydroxypropyl methylcellulose (HPMC), hydroxypropyl ethylcellulose (HPEC), ndi hydroxypropyl cellulose (HPC).

HPMC ndi yosunthika komanso yogwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana. Magiredi osiyanasiyana a HPMC amatengera kuchuluka kwa m'malo, kukula kwa tinthu, ndi mtundu wa gulu la hydroxypropyl, ndipo giredi iliyonse ili ndi katundu wake ndi ntchito zake.
