He aha te Hydroxypropyl methylcellulose?

1. Kupu Whakataki

Ko te Hydroxypropyl methylcellulose (HPMC) he polymer wairewa-wairewa e whakamahia nuitia ana i ahu mai i te cellulose. Ko te paura kore-katote, te kakara, te reka, te ma ki te ma-ma te paura e whakamahia nuitia ana i roto i nga umanga kai, rongoa, me nga umanga whakapaipai. He maha nga momo tono a HPMC, tae atu ki te whakapakeke, te whakaemulsifying, te whakatarewa, te whakapumau, me te hanga kiriata. Ka whakamahia ano hoki hei here, hei whakahinuhinu, hei whakakore i roto i te hanga papa me nga capsules.

2. Raw Materials

Ko te rauemi mata matua e whakamahia ana ki te whakaputa HPMC ko te cellulose, he polysaccharide i tito i nga waeine huka. Ka taea te tiki mai i te cellulose mai i nga momo puna, tae atu ki te penupenu rakau, te miro, me etahi atu muka tipu. Ka tukuna te cellulose ki tetahi tukanga matū hei whakaputa i te hydroxypropyl methylcellulose.

3. Tukanga Hangahanga

Ko te tukanga hangahanga o te HPMC he maha nga waahanga. Tuatahi, ka tukuna te cellulose ki te kawakore, penei i te konutai hydroxide, hei hanga i te cellulose alkali. Ka tauhohehia tenei cellulose alkali ki te methyl chloride me te propylene oxide ki te hanga hydroxypropyl methylcellulose. Ka purea te hydroxypropyl methylcellulose ka whakamaroke kia puta he paura ma.

4. Mana Kounga

Ko te mana o te kounga he waahanga nui o te mahi hangahanga o te HPMC. Ko te kounga o te hua ka whakatauhia e te ma o te cellulose, te tohu o te whakakapi o te roopu hydroxypropyl, me te tohu o te whakakapi o te roopu methyl. Ko te ma o te cellulose ka whakatauhia ma te whakamatautau i te viscosity o te otinga, ko te tohu o te whakakapinga ka whakatauhia ma te whakamatautau i te tohu o te hydrolysis o te hydroxypropyl methylcellulose.

5. Whakapaipai

Ko te HPMC te nuinga o te waa ki roto i nga peeke, i nga pahu ranei. Ko nga peke he mea hanga ki te polyethylene, ki te polypropylene ranei, i te nuinga o te waa ka mahia nga pahu ki te maitai, ki te kirihou ranei. Me kowhiria nga mea whakangao hei whakarite kia tiakina te hua mai i te makuku me etahi atu mea taiao.

6. Rokiroki

Me penapena te HPMC ki te waahi makariri, maroke, kia matara atu i te ra me etahi atu puna wera. Me tiaki hoki te hua mai i te makuku me etahi atu mea taiao.

7. Whakamutunga

Ko te HPMC he polymer wairewa-wairewa e whakamahia nuitia ana i ahu mai i te cellulose. Ka whakamahia i roto i nga momo ahumahi, tae atu ki te kai, te rongoa, me te ahumahi whakapaipai. Ko te tukanga hangahanga o te HPMC he maha nga waahanga, tae atu ki te maimoatanga o te cellulose me te alkali, te tauhohenga o te cellulose alkali me te methyl chloride me te propylene oxide, me te purenga me te whakamaroke o te hydroxypropyl methylcellulose. Ko te mana o te kounga tetahi waahanga nui o te mahi whakangao, me penapena te hua ki te waahi makariri, maroke, kia matara atu i te ra me etahi atu puna wera.
