Hydroxypropyl Methyl Cellulose HPMC Transparency

Kuwonekera kwapamwamba komanso magwiridwe antchito okhazikika.

HPMC ali ndi katundu wa matenthedwe gelation.The mankhwala amadzimadzi njira ndi mkangano kupanga gel osakaniza ndi precipitates, ndiyeno dissolves pambuyo kuzirala.Kutentha kwa gelation kwazinthu zosiyanasiyana kumasiyana.Kusungunuka kumasiyanasiyana ndi kukhuthala.M'munsi mamasukidwe akayendedwe, kwambiri solubility.Mafotokozedwe osiyanasiyana a HPMC ali ndi kusiyana kwina kwa katundu wawo, ndipo kusungunuka kwa HPMC m'madzi sikukhudzidwa ndi pH mtengo.

Kukula kwa tinthu: 100 mesh pass rate ndi yayikulu kuposa 98.5%.

Kachulukidwe kachulukidwe: 0.25-0.70g/ (nthawi zambiri pafupifupi 0.4g/), mphamvu yokoka yeniyeni 1.26-1.31.

Kutentha kwa kutentha: 200-200 ° C,

Kutentha kwa carbonation: 280-300 ° C.

Mtengo wa Methoxy 19.0% mpaka 30.0%,

Mtengo wa Hydroxypropyl 4% mpaka 12%.

Viscosity (22 ℃, 2%) 5 ~ 200000mPa.s.

Kutentha kwa gel (0.2%) ndi 50-90 ° C.

HPMC ali ndi makhalidwe thickening luso, kukhetsa mchere, PH bata, kusunga madzi, dimensional bata, kwambiri mafilimu kupanga katundu ndi osiyanasiyana enzyme kukana, dispersibility ndi cohesiveness.
