Musiyano Pakati peEHEC neHPMC

EHEC neHPMC maviri anowanzo shandiswa marudzi emapolima ane akasiyana makemikari zvimiro uye zvimiro.EHEC inomirira ethyl hydroxyethyl cellulose, ukuwo HPMC ichimirira hydroxypropyl methylcellulose.Muchikamu chino, tichakurukura kusiyana kweEHEC neHPMC maererano nemakemikari avo, zvivakwa, kushandiswa, uye kuchengeteka.

1. Kemikari Yakarongeka

EHEC ipolmer inonyungudika mumvura inotorwa kubva muselulosi.Iyo yakagadziridzwa cellulose ether ine ese ethyl uye hydroxyethyl mapoka akabatanidzwa kune cellulose musana.The degree of substitution (DS) yeEHEC inoreva nhamba ye ethyl uye hydroxyethyl mapoka aripo pane anhydroglucose unit (AGU) ye cellulose musana.Iyo DS yeEHEC inogona kubva pa0.2 kusvika 2.5, ine yakakwirira DS kukosha inoratidza dhigirii repamusoro rekutsiva.

HPMC, kune rumwe rutivi, zvakare iri mumvura-inonyungudika polima iyo inotorwa kubva ku cellulose.Iyo yakagadziridzwa cellulose ether ine ese ari maviri hydroxypropyl uye methyl mapoka akabatanidzwa kune cellulose musana.Iyo dhigirii yekutsiva yeHPMC inoreva huwandu hwehydroxypropyl uye methyl mapoka aripo paAGU ye cellulose musana.Iyo DS yeHPMC inogona kubva pa0.1 kusvika 3.0, ine yakakwirira DS kukosha inoratidza dhigirii repamusoro rekutsiva.

2. Properties

EHEC neHPMC vane zvivakwa zvakasiyana zvinoita kuti ive yakakodzera kune akasiyana mafomu.Zvimwe zvezvinhu zvakakosha zveEHEC neHPMC zvakanyorwa pazasi:

a.Solubility: EHEC haina kunyungudika mumvura kupfuura HPMC, uye kunyungudika kwayo kunoderera sezvo dhigirii rekutsinhanisa rinowedzera.HPMC, kune rumwe rutivi, inonyungudika zvakanyanya mumvura.

b.Rheology: EHEC ndeye pseudoplastic material, zvinoreva kuti inoratidza shear kuonda maitiro.Izvi zvinoreva kuti viscosity yeEHEC inoderera sezvo shear rate inowedzera.HPMC, kune rumwe rutivi, iNewtonian material, zvinoreva kuti viscosity yayo inoramba iripo pasinei neshear rate.

c.Mafirimu ekugadzira zvinhu: EHEC ine maitiro akanaka ekugadzira firimu, iyo inoita kuti ive yakakodzera kushandiswa mukuputira uye mafirimu.HPMC zvakare ine mafirimu-ekugadzira zvimiro, asi iwo mafirimu anogona kunge asina brittle uye ari nyore kupaza.

d.Kugadzikana: EHEC yakagadzikana pamusoro pehupamhi hwepH uye tembiricha mamiriro.HPMC zvakare yakagadzikana pamusoro pehupamhi pH renji, asi kugadzikana kwayo kunogona kukanganiswa nekupisa kwakanyanya.

3. Uses

EHEC uye HPMC inoshandiswa mumhando dzakasiyana-siyana dzekushandisa mumaindasitiri ezvekudya, emishonga, uye ega ega.Zvimwe zvekushandisa zvakakosha zveEHEC neHPMC zvakanyorwa pazasi:

a.Indasitiri yechikafu: EHEC inowanzoshandiswa seyakakora, stabilizer, uye emulsifier muzvigadzirwa zvekudya zvakaita sesosi, madhirezi, uye zvinhu zvakabikwa.HPMC inoshandiswawo seyakakora uye inodzikamisa muzvigadzirwa zvekudya, asi inonyanya kushandiswa sechinhu chinoputira chezvigadzirwa zvema confectionery senge gummy candies nemachokoreti.

b.Indasitiri yemishonga: EHEC inoshandiswa sebhainda, disintegrant, uye piritsi rekuvhara mumiriri mukugadzirwa kwemishonga.HPMC inoshandiswawo sebhainda, disintegrant, uye piritsi rekuvhara mumiriri mukugadzira mishonga, asi inonyanya kushandiswa seyakagadziriswa-inoburitsa mumiriri.

4. Safety

EHEC neHPMC zvinowanzoonekwa zvakachengeteka kushandiswa mukudya uye mishonga yemishonga.Nekudaro, sekunge chero chinhu chemakemikari, panogona kunge paine njodzi dzine chekuita nekushandiswa kwavo.
