Hydroxypropyl methylcellulose (HPMC) tikanga whakakore:

Ina whakapirihia nga hua o te hydroxypropyl methylcellulose (HPMC) ki te wai, ka whakakotahi, ka memeha, engari he tino puhoi, he uaua hoki tenei whakakorenga. E toru nga tikanga whakakore i raro nei, a ka taea e nga kaiwhakamahi te whiriwhiri i te tikanga tino watea kia rite ki ta raatau whakamahinga:

1. Tikanga wai wera: I te mea karekau te hydroxypropyl methylcellulose (HPMC) e memeha ki te wai wera, ko te wahanga tuatahi o te hydroxypropyl methylcellulose (HPMC) ka taea te marara ki te wai wera, katahi ka whakamataohia, e toru He tikanga angamaheni e whakaahuatia ana hei e whai ake nei:

1). Kuhua te nui o te wai wera ki roto i te ipu ka whakamahana ki te 70°C. Āta tāpirihia te hydroxypropyl methylcellulose (HPMC) i raro i te whakaoho puhoi, ka timata te hydroxypropyl methylcellulose (HPMC) ki te rewa i runga i te mata o te wai, katahi ka hanga he slurry, whakamatao i te slurry i raro i te whakaoho.

2). Whakawerahia te 1/3, te 2/3 ranei (te nui e hiahiatia ana) o te wai i roto i te ipu ka whakamahana ki te 70°C. E ai ki te tikanga o 1), whakamararatia hydroxypropyl methylcellulose (HPMC) ki te whakarite slurry wai wera; Kātahi ka tāpirihia te toenga o te wai matao, te wai tio rānei ki roto i te ipu, kātahi ka tāpirihia te slurry wai wera hydroxypropyl methylcellulose (HPMC) kua whakahuahia ake nei ki te wai matao, ka whakaoho, ka whakamataohia te ranunga.

3). Tuhia he 1/3, 2/3 ranei o te nui o te wai e hiahiatia ana ki roto i te ipu ka whakamahana ki te 70°C. E ai ki te tikanga o te 1), whakamararatia te hydroxypropyl methylcellulose (HPMC) ki te whakarite i te slurry wai wera; Ko te toenga o te wai matao, wai tio ranei ka tapirihia ki te wai wera ka whakamataohia te ranunga i muri i te whakaoho.

2. Te tikanga whakaranu paura: ko nga matūriki paura hydroxypropyl methylcellulose (HPMC) me te rite, nui ake ranei o etahi atu mea paura ka tino marara ma te whakamaroke maroke, katahi ka rewa ki te wai, katahi ka rewa te hydroxypropyl methylcellulose Base cellulose (HPMC) kaore he agglomeration. . 3. Tikanga makuku whakarewa pararopi: i mua i te marara, i te makuku hydroxypropyl methylcellulose (HPMC) me nga whakarewa pararopi penei i te waihano, te ethylene glycol, te hinu ranei, katahi ka memeha ki te wai. I tenei wa, ka taea hoki te rewa te hydroxypropyl methylcellulose ( HPMC).
