Limaraka tse fapaneng tsa HPMC ke life?

HPMC, kapa hydroxypropyl methylcellulose, ke mofuta oa selulose e tsoang ho selulose eo hangata e sebelisoang e le sekontiri, emulsifier, le stabilizer lihlahisoa tse fapaneng.Ke phofo e tšoeu, e sa nkhang hamonate, e sa latsoeheng e qhibilihang metsing a batang 'me e sa qhibilihe metsing a chesang.

HPMC e fumaneha ka limaraka tse fapaneng, e 'ngoe le e 'ngoe e na le thepa ea eona e ikhethang le lits'ebetso.Likarolo tsa HPMC li ipapisitse le tekanyo ea ho fetola (DS) ea lihlopha tsa hydroxypropyl, e leng tekanyo ea palo ea lihlopha tsa hydroxypropyl ho yuniti ea anhydroglucose.Ha DS e phahame, ho na le lihlopha tse ngata tsa hydroxypropyl 'me HPMC e ba le hydrophilic haholoanyane.

Limaraka tsa HPMC li arotsoe ka mekhahlelo e meraro: DS e tlase, DS e mahareng, le DS e phahameng.

Low DS HPMC hangata e sebelisoa lits'ebetsong moo ho batloang viscosity e tlase le matla a tlase a gel.Sehlopha sena se atisa ho sebelisoa ha ho sebelisoa lijo le lino, tse kang ice cream, li-sauces le li-gravies.E boetse e sebelisoa lits'ebetsong tsa meriana, joalo ka matlapa le li-capsules.

Medium DS HPMC e sebelisoa lits'ebetsong moo ho batloang viscosity e phahameng le matla a gel.Kereiti ena hangata e sebelisoa lits'ebetsong tsa lijo le lino, joalo ka jam le jellies, hammoho le lits'ebetsong tsa meriana, joalo ka litlolo le litlolo.

High DS HPMC e sebelisoa lits'ebetsong moo ho batloang viscosity e phahameng haholo le matla a gel.Kereiti ena hangata e sebelisoa lits'ebetsong tsa lijo le lino, joalo ka chisi le yogurt, hammoho le lits'ebetsong tsa meriana, joalo ka li-suppositories le pessaries.

Ntle le mekhahlelo e meraro ea mantlha ea HPMC, ho boetse ho na le likaroloana tse 'maloa.Likaroloana tsena li ipapisitse le boemo ba phalliso, boholo ba likaroloana, le mofuta oa sehlopha sa hydroxypropyl.

Tekanyo ea li-substitute subcategories e ipapisitse le boemo ba ho nka sebaka sa lihlopha tsa hydroxypropyl.Likaroloana tsena ke DS e tlase (0.5-1.5), DS e mahareng (1.5-2.5), le DS e phahameng (2.5-3.5).

The particle size subcategories e ipapisitse le boholo ba likaroloana.Likaroloana tsena li ntle (ka tlase ho li-microns tse 10), tse mahareng (10-20 microns), le mahoashe (li-microns tse fetang 20).

Mofuta oa likaroloana tsa sehlopha sa hydroxypropyl o ipapisitse le mofuta oa sehlopha sa hydroxypropyl se teng ho HPMC.Likaroloana tsena ke hydroxypropyl methylcellulose (HPMC), hydroxypropyl ethylcellulose (HPEC), le hydroxypropyl cellulose (HPC).

HPMC ke motsoako o sebetsang ka bongata le o sebelisoang haholo lihlahisoa tse fapaneng.Mephato e fapaneng ea HPMC e ipapisitse le boemo ba phapanyetso, boholo ba likaroloana, le mofuta oa sehlopha sa hydroxypropyl, 'me sehlopha ka seng se na le thepa le lits'ebetso tse ikhethang.
