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, ka taea te marara tuatahi o te hydroxypropyl methylcellulose (HPMC) ki te wai wera, katahi ka whakamatao, 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).
