Hydroxypropyl Methyl Cellulose HPMC Transparency

Ponaletso e phahameng le tshebetso e tsitsitseng.

HPMC e na le thepa ea gelation ea mocheso. Sehlahisoa tharollo ea aqueous e futhumetse ho etsa gel le precipitates, ebe e qhibiliha ka mor'a ho pholile. Mocheso oa gelation oa litlhaloso tse fapaneng o fapane. Sollubility e fapana ho ea ka viscosity. The viscosity e ka tlaase, e kholoanyane ea ho qhibiliha. Litlhaloso tse fapaneng tsa HPMC li na le phapang e itseng linthong tsa tsona, 'me ho qhibiliha ha HPMC metsing ha ho amehe ke boleng ba pH.

Boholo ba likaroloana: Sekhahla sa ho feta sa 100 mesh se seholo ho feta 98.5%.

Boima ba bongata: 0.25-0.70g/ (hangata hoo e ka bang 0.4g/), matla a khoheli a itseng 1.26-1.31.

Mocheso oa mocheso: 200-200 ° C,

Mocheso oa carbonization: 280-300°C.

Methoxy boleng 19.0% ho 30.0%,

Hydroxypropyl boleng ba 4% ho isa ho 12%.

Viscosity (22℃, 2%) 5～200000mPa.s.

Thempereichara ea gel (0.2%) ke 50-90°C.

HPMC e na le litšoaneleho tsa bokhoni ba ho tenya, ho tsoa letsoai, botsitso ba PH, ho boloka metsi, botsitso ba mahlakore, thepa e babatsehang ea ho etsa filimi le mefuta e mengata ea ho hanyetsa li-enzyme, ho arohana le ho kopana.
