IHydroxypropyl Methyl Cellulose HPMC Transparency

Ukucaca okuphezulu nokusebenza okuzinzile.

I-HPMC inendawo ye-thermal gelation.Isixazululo se-aqueous somkhiqizo siyashiswa ukuze senze ijeli futhi sikhuphuke, bese siyancibilika ngemva kokupholisa.Izinga lokushisa le-gelation lokucaciswa okuhlukile lihlukile.I-Solubility iyahlukahluka ngokuya nge-viscosity.I-viscosity ephansi, i-solubility enkulu.Ukucaciswa okuhlukile kwe-HPMC kunomehluko othile ezimpahleni zayo, futhi ukuhlakazwa kwe-HPMC emanzini akuthintwa inani le-pH.

Usayizi we-particle: Izinga lokuphasa le-100 mesh likhulu kuno-98.5%.

Ukuminyana kwenqwaba: 0.25-0.70g/ (imvamisa cishe ngo-0.4g/), amandla adonsela phansi athile 1.26-1.31.

Ukushisa kombala: 200-200 ° C,

Ukushisa kwe-Carbonization: 280-300°C.

Inani le-Methoxy 19.0% kuya ku-30.0%,

Inani le-Hydroxypropyl 4% kuya ku-12%.

I-Viscosity (22℃, 2%) 5～200000mPa.s.

Izinga lokushisa lejeli (0.2%) lingu-50-90°C.

I-HPMC inezici zekhono lokuqina, ukukhipha usawoti, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, indawo enhle kakhulu yokwenza ifilimu kanye nohlu olubanzi lokumelana nama-enzyme, ukuhlakazeka nokuhlangana.
