Kusiyana pakati peHPS neHPMC
Hydroxypropyl starch(HPS) uyeHydroxypropyl methyl cellulose(HPMC) maviri anowanzo shandiswa mapolysaccharides mune akasiyana maindasitiri ekushandisa, kusanganisira mishonga, chikafu, uye kuvaka. Zvisinei nekufanana kwadzo, HPS neHPMC vane misiyano yakasiyana mune zvemuviri nemakemikari zvimiro, pamwe nemabasa avo ekushanda. Muchikamu chino, tichaongorora mutsauko uripo pakati peHPS neHPMC maererano nechimiro chavo chemakemikari, zvivakwa, uye mashandisirwo.
Mushonga Wemakemikari
HPS inobuda sitachi inowanikwa nekugadzirisa makemikari starch yechisikigo nemapoka ehydroxypropyl. Mapoka ehydroxypropyl anonamirwa kumapoka ehydroxyl pane starch molecule, zvichikonzera starch yakagadziridzwa ine solubility yakagadziridzwa uye kugadzikana. HPMC, kune rumwe rutivi, inotorwa neselulosi iyo inowanikwa nemakemikari ekugadzirisa cellulose ine hydroxypropyl uye methyl mapoka. Iwo mapoka ehydroxypropyl akasungirirwa kumapoka ehydroxyl pane cellulose molecule, nepo mapoka emethyl akasungirirwa kune anhydroglucose unit.
Properties
HPS uye HPMC vane akasiyana emuviri uye makemikari zvimiro zvinoita kuti ive yakakodzera kune akasiyana maapplication. Zvimiro zveHPS zvinosanganisira:
- Solubility: HPS inonyungudika mumvura uye inogona kugadzira mhinduro dzakajeka pakudzika kwakadzika.
- Viscosity: HPS ine viscosity yakaderera kana ichienzaniswa neHPMC nemamwe mapolysaccharides.
- Kugadzikana: HPS yakagadzikana pane dzakasiyana siyana tembiricha uye pH nhanho uye inoshingirira kune ma enzymes uye zvimwe zvinoparadza.
- Gelation: HPS inogona kuumba gels inodzoreredza inodzoreredza pamatunhu akakwira, izvo zvinoita kuti ive yakakodzera kune dzakasiyana siyana chikafu uye mishonga yekushandisa.
Zvimiro zveHPMC zvinosanganisira:
- Solubility: HPMC inonyungudika mumvura uye inoumba mhinduro dzakajeka pane dzakaderera.
- Viscosity: HPMC ine yakakwira viscosity uye inogona kugadzira viscous mhinduro kunyangwe panguva yakaderera.
- Kugadzikana: HPMC yakagadzikana pane dzakasiyana siyana tembiricha uye pH mazinga uye inoshingirira kune maenzayimu uye zvimwe zvinoparadza.
- Kugona kugadzira firimu: HPMC inogona kugadzira mafirimu akatetepa, anochinjika ayo anobatsira mumishonga yakasiyana-siyana yemishonga uye yekuzora.
Applications
HPS neHPMC vane maapplication akasiyana nekuda kwezvivakwa zvavo zvakasiyana. Zvikumbiro zveHPS zvinosanganisira:
- Zvokudya: HPS inoshandiswa seyakakora uye inodzikamisa muzvigadzirwa zvekudya zvakasiyana-siyana, zvakadai sesoso, muto, uye marokwe.
- Pharmaceutical: HPS inoshandiswa sebhainda uye disintegrant mumapiritsi nemakapisi uye semotokari yekuendesa zvinodhaka.
- Kuvaka: HPS inoshandiswa seyakakora uye bhainda muzvigadzirwa-samende, sedhaka nekongiri.
Zvikumbiro zveHPMC zvinosanganisira:
- Chikafu: HPMC inoshandiswa seyakakora uye inodzikamisa mune dzakasiyana siyana zvigadzirwa zvekudya, senge ice cream, yogati, uye zvakabikwa zvinhu.
- Pharmaceutical: HPMC inoshandiswa sebinder, disintegrant, uye firimu-forming agent mumapiritsi uye capsules uye semotokari yekuendesa zvinodhaka.
- Kuzvichengeta Pamunhu: HPMC inoshandiswa muzvigadzirwa zvakasiyana-siyana zvekuchengeta munhu, senge lotions, shampoos, uye zvekuzora, semukobvu nekudzikamisa.
- Kuvaka: HPMC inoshandiswa seyakakora uye bhainda mune simende-yakagadzirwa zvigadzirwa, sedhaka nekongiri, uye sechinhu chinonamira pazvinhu zvekuvaka.
Mhedziso
Mukupedzisa, HPS uye HPMC mapolysaccharides maviri anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana. HPS inotorwa starch ine yakadzikira viscosity, inodzoreredzwa nemafuta, uye yakagadzikana pakusiyana kwetembiricha uye pH mazinga. HPMC, kune rumwe rutivi, ndeye cellulose yakabva kune yakakwira viscosity, inogona kuumba akatetepa, anochinjika mafirimu, uye zvakare yakagadzikana pahupamhi hwetembiricha uye pH mazinga. Misiyano iri pakati pemakomboni maviri aya inoita kuti ikwane kune akasiyana mashandisirwo mumaindasitiri akasiyana, kusanganisira chikafu, mishonga yemishonga, kuchengetwa kwemunhu, uye kuvaka.
Panyaya yechimiro chavo chemakemikari, HPS isitashi yakagadziridzwa ine hydroxypropyl mapoka, nepo HPMC iri yakagadziridzwa cellulose ine ese hydroxypropyl uye methyl mapoka. Musiyano uyu muchimiro chemakemikari unobatsira kune akasiyana emuviri uye makemikari zvimiro zveaya macomputer, akadai solubility, viscosity, kugadzikana, uye gelation kana firimu-kugadzira kugona.
Iko kushandiswa kweHPS neHPMC kwakasiyanawo nekuda kwezvivakwa zvavo zvakasiyana. HPS inowanzoshandiswa seyakakora uye kudzikamisa muzvigadzirwa zvekudya, binder uye disintegrant mumishonga yemishonga, uye thickener uye binder mune zvekuvaka. Zvichakadaro, HPMC inoshandiswa zvakanyanya seyakakora uye inodzikamisa muzvigadzirwa zvechikafu, binder, disintegrant, uye firimu-inogadzira mumiriri mumishonga, thickener uye stabilizer muzvigadzirwa zvekuchengeta munhu, uye thickener, binder, uye coating agent mune zvekuvaka.
Muchidimbu, HPS neHPMC maviri anowanzo shandiswa polysaccharides ane akasiyana makemikari zvimiro, zvemuviri uye makemikari zvimiro, uye mashandisiro mumaindasitiri akasiyana. Kunzwisisa mutsauko uripo pakati pemakomponi maviri aya kwakakosha pakusarudza zvinhu zvakakodzera zvekushandisa chaiko uye kugadzirisa mashandiro avo mumaindasitiri akasiyana siyana.
