He aha te nui o to mohio mo Hydroxypropyl methyl cellulose?

Ko te Hydroxypropyl methylcellulose (HPMC) he ether cellulose i ahu mai i te cellulose taiao.He polymer waihanga, wai-wairewa, kore-katote e whakamahia ana i roto i nga momo ahumahi penei i te hangahanga, te rongoa, te kai, te whakapaipai, me nga kakano.

Ka puta te HPMC ma te whakarereke matū i te cellulose me te propylene oxide me te methyl chloride hei whakauru i nga roopu hydroxypropyl me te methyl ki roto i te ngota ngota cellulose.Ko te tohu whakakapinga (DS) o HPMC e pa ana ki te maha o nga roopu hydroxypropyl me te methyl mo ia wae anhydroglucose (AGU) o te cellulose.

He maha nga taonga a HPMC e whai hua ana ki nga momo tono.He wairewa i roto i te wai, ka hanga he otinga maamaa, he pai te pumau o te waiariki.He pumau ano i raro i nga ahuatanga o te pāmahana me te pH, kaore e ngawari te pirau.Ko te HPMC he hygroscopic, ko te tikanga ka taea e ia te tango me te pupuri i te makuku.Kaore he paitini, kaore i te whakapataritari, me te kore-allergenic, e noho haumaru ana mo te whakamahi i nga tono maha.

I roto i te ahumahi hangahanga, ka whakamahia te HPMC hei pupuhi, hei here, hei pupuri i te wai i roto i nga hua o te ciment, te whakapiri tile, te raima, me etahi atu mea hanga.I roto i te ahumahi ho'oraa, ka whakamahia te HPMC hei here, te whakakore, me te kiriata-o mua i roto i te papa me te hanganga capsule.I roto i te ahumahi kai, ka whakamahia te HPMC hei whakakaha, whakaehunga me te whakapumau i roto i nga momo hua.I roto i nga mea whakapaipai, ka whakamahia te HPMC hei whakamaroke, kiriata-mua, me te emulsifier i roto i nga kirīmi, hinu, me etahi atu hanganga.

I roto i te katoa, ko te HPMC he polymer whaihua me te whai hua he maha nga tono i roto i nga momo ahumahi na ona ahuatanga ahurei.
