▲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
Waihohydroxypropyl methyl cellulose (HPMC)ki roto i te wai hei hanga i te kohinga marama, me te tirotiro i tana whakawhiti maama. 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.
