1. Te mahana o te ra (0.2% otinga) 50-90°C.
2. Ka whakarewahia i roto i te wai me te nuinga o te polar c me te wahanga tika o te waiwaro/wai, propanol/wai, dichloroethane, me etahi atu, kare e rewa i roto i te etera, te acetone, te waihano tino, ka pupuhi ki roto ki te wai maataa, paku pakupaku ranei i roto i te wai matao wairewa colloidal.Ko te wairewa wai he mahi mata, he tino marama me te mahi pumau.
3. Kei a HPMC te taonga o te waiariki.Ka whakamahanahia 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.
4. Te rahi o te matūriki: 100 te reiti 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: 180-200°C, te whakamahana waro: 280-300°C.Ko te uara methoxyl mai i te 19.0% ki te 30.0%, me te uara hydroxypropyl mai i te 4% ki te 12%.Viscosity (22°C, 2%) 5～200000mPa .s.Te mahana o te ra (0.2%) 50-90°C
5. Ko te HPMC nga ahuatanga o te kaha ki te whakapaoho, te tote tote, te pumau o te PH, te pupuri wai, te pumau o te rahi, te tino pai o te hanga kiriata, te whanuitanga o te aukati i te whana, te whakamararatanga me te whakakotahitanga.
