Me pehea te tautuhi i te kounga HPMC?

 te hydroxypropyl methyl cellulose (HPMC) he kakara, he koretake, he paura ma-paitini. I muri i te rewa tino ki te wai, ka hangaia e te hydroxyproprose te cellulise maramarama.

 nga rauemi matua o te hydroxypropyl methyl cellulose (HPMC): Ko te miro, te methyl chloride, me etahi atu taonga mata, me te waikawa, toluene, isopropanol, etc.

Te whakataurite o nga painga me nga ngoikoretanga o te hydroxypropyl methyl cellulose:
1.Puhia te hydroxypropyl methyl cellulose hpmc he wewete i te ahua me te tino nui o te 0.3-0.4 / ml.
Ko te HPMC kua mate he tino pai te ahua o te HPMC me te tino taumaha, he rereke te rereke mai i te hua pono o te ahua.
2.Puhia te hydroxypropyl methyl cellulose hpmc selllose home roauous he maamaa, he maama te maramatanga o te wai, te utu pupuri i te wai> 97%.
Ko te otinga o te HPMC kua moe he paru te paru, ko te utu pupuri i te wai he uaua ki te eke ki te 80%.
3.Ko te HPMC kaua e hongi i te haukini, te māngaro me te waipiro.
Ka taea e te HPMC te tino hongi i nga momo otaota katoa, ahakoa he koretake, ka nui te taumaha.
4.Pure hydroxypropyll methyl cellulose hpmc paura HPMC parddder i raro i te whaikorero me te karaihe whakanui ranei.
Ka taea te kite i te HPMC kua whakapaehia hei karaihe, he tioata ranei i raro i te karaihe, i te karaihe whakanui ranei.

Mai i nga waahanga hei tautuhi i nga painga me nga ngoikoretanga o te hydroxypropyl cellulose?
1.Whaka tohu
Ahakoa kaore e taea e te ma te whakatau mehemea he ngawari te whakamahi a te HPMC, a ki te taapiri i nga kaihoko whitening i te wa o te mahinga whakaputa, ka pa ki tona kounga. Heoi, ko te nuinga o nga hua pai he ma pai.

2.NENENENES
Ko te pai o te HPMC e 80 nga taara me te 100, me te kai, me te pai rawa atu, ko te korero, ko te pai ake.
3.TransmitTance
Whakanohia te CelluxyPropyl methyl cellulose (HPMC) ki te wai hei hanga i te kolloid marama, me te tirotiro i tana whakawhiti marama. Ko te teitei o te whakawhiti maama, ko te pai ake, e whakaatu ana i nga mea iti ake i roto i a ia. Ko te ahua o nga kaiwhakanao poutū he pai, ahakoa he kino ake te kino o nga kaiwhakaora whakapae.

Tangahanga 4.Protia
Ko te nui ake o te kaha motuhake, ko te mea nui ake te nui ake. He nui te motuhake, na te mea he nui te kiko o te roopu hydroxypropyl i roto, ko te kiko o te roopu hydroxypropyl, he pai ake te pupuri wai.
