Hydroxypropyl Methyl Cellulose HPMC Puataata

He maamaa teitei me te mahi pumau.

Kei a HPMC te taonga o te waiariki waiariki. Ka whakamahana te wairewa wai hua ki te hanga i te reera ka heke, ka memeha i muri i te whakamatao. He rereke te pāmahana o te reera o nga whakaritenga rereke. He rereke te wairewa ki te pokey. Ko te iti o te pokey, ka nui ake te whakarewatanga. Ko nga korero rereke o te HPMC he rereke nga ahuatanga, a ko te whakakorenga o te HPMC i roto i te wai kaore e pa ki te uara pH.

Te rahi o te matūriki: 100 te reeti whakawhiti mata he nui ake i te 98.5%.

Kiato rahi: 0.25-0.70g/ (te nuinga o te 0.4g/), te taumaha motuhake 1.26-1.31.

Te wera o te tae: 200-200°C,

Te pāmahana waro: 280-300°C.

Uara Methoxy 19.0% ki te 30.0%,

Hydroxypropyl uara 4% ki te 12%.

Viscosity (22℃, 2%) 5～200000mPa.s.

Ko te pāmahana reera (0.2%) he 50-90°C.

Kei a HPMC nga ahuatanga o te kaha ki te whakapakeke, te tote tote, te pumau o te PH, te pupuri i te wai, te pumau o te rahi, te tino pai o te hanga kiriata me te whānuitanga o te aukati i te whaariki, te whakamararatanga me te whakakotahitanga.
