Ndeupi musiyano uripo pakati peHPMC E neK?

HPMC (Hydroxypropyl Methylcellulose) imhando ye cellulose ether inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira mishonga, chikafu, zvizorwa, uye kuvaka. HPMC isiri-ionic, mvura-inonyungudika polima yakabva muselulosi, uye inowanikwa mumhando mbiri: HPMC E uye HPMC K.

HPMC E igiredhi yakaderera-viscosity yeHPMC, uye inoshandiswa zvakanyanya mumishonga yemishonga. Inoshandiswa sebhainda, disintegrant, uye kumisa mumiriri mumapiritsi, capsules, uye granules. Iyo inoshandiswa zvakare seyakakora mumiriri mumasyrups, makirimu, uye ekuzora. HPMC E igiredhi yakaderera-viscosity, zvichireva kuti ine yakaderera viscosity kana yakanyungudika mumvura. Izvi zvinoita kuti ive yakakodzera kushandiswa mumishonga yemishonga, sezvo iri nyore kusanganisa uye kuparadzira mumvura.

HPMC K igiredhi repamusoro-viscosity reHPMC, uye rinoshandiswa zvakanyanya mukuvaka uye kugadzira chikafu. Inoshandiswa sechibhainda, chikobvu, uye chinomisikidza muzvinhu zvekuvakisa, sematairi anonamira, magiroti, uye plasters. Inoshandiswawo seyakakora muzvigadzirwa zvekudya, senge jamu, jellies, uye sosi. HPMC K igiredhi repamusoro-viscosity, zvichireva kuti ine viscosity yakakwirira kana yakanyungudika mumvura. Izvi zvinoita kuti ive yakakodzera kushandiswa mukuvaka uye chikafu chekudya, sezvo ichikwanisa kupa gobvu, viscous kuenderana.

Musiyano mukuru pakati peHPMC E uye HPMC K ndiyo viscosity. HPMC E igiredhi yakaderera-viscosity, zvichireva kuti ine yakaderera viscosity kana yakanyungudika mumvura. Izvi zvinoita kuti zvive zvakanaka kushandiswa mumishonga yemishonga, sezvo zviri nyore kusanganisa uye kuparadzira mumvura. HPMC K igiredhi repamusoro-viscosity, zvichireva kuti ine viscosity yakakwirira kana yakanyungudika mumvura. Izvi zvinoita kuti ive yakakodzera kushandiswa mukuvaka uye chikafu chekudya, sezvo ichikwanisa kupa gobvu, viscous kuenderana.

Kuwedzera kune viscosity, HPMC E uye HPMC K inosiyanawo maererano nechimiro chavo chemakemikari. HPMC E ine yakaderera molecular uremu pane HPMC K, izvo zvinopa yakaderera viscosity. HPMC K ine huremu hwemamorekuru hwepamusoro, hunoipa huremu hwepamusoro.

Chekupedzisira, HPMC E uye HPMC K zvakare akasiyana maererano nekunyungudika kwavo. HPMC E inonyungudika mumvura inotonhora, ukuwo HPMC K inonyungudika mumvura inopisa. Izvi zvinoita kuti HPMC E ive yakakodzera kushandiswa mumishonga yemishonga, sezvo inogona kusanganiswa nyore nyore uye yakaparadzirwa mumvura inotonhora. HPMC K yakanakira kushandiswa mukuvaka uye kudya kwekudya, sezvo inogona kusanganiswa nyore nyore uye yakaparadzirwa mumvura inopisa.

Mukupedzisa, musiyano mukuru pakati peHPMC E uye HPMC K ndiyo viscosity. HPMC E igiredhi yakaderera-viscosity, nepo HPMC K iri giredhi repamusoro-viscosity. Mukuwedzera, HPMC E ine yakaderera molecular uremu pane HPMC K, uye inonyungudika mumvura inotonhora, nepo HPMC K inonyungudika mumvura inopisa. Misiyano iyi inoita kuti HPMC E uye HPMC K zvive zvakanaka kuti zvishandiswe mumashandisirwo akasiyana.
