Musiyano Pakati peCMC neHPMC

Carboxymethyl cellulose (CMC) uye hydroxypropyl methylcellulose (HPMC) marudzi maviri ezvinobva muselulosi anoshandiswa zvakanyanya mumaindasitiri ezvekudya, emishonga, uye ega ega. Nepo ese ari maviri achishandiswa seakobvu, anosimbisa, uye emulsifiers, kune mimwe misiyano yakakosha pakati peCMC neHPMC inoita kuti ive yakakodzera kune akasiyana maapplication. Muchikamu chino, tichakurukura mutsauko uripo pakati peCMC neHPMC maererano nechimiro chavo chemakemikari, zvivakwa, mashandisiro, uye chengetedzo.

1. Mushonga Wemakemikari

CMC ipolymer inonyungudika nemvura inotorwa kubva ku cellulose, inova polima yechisikigo inowanikwa mumadziro esero rezvirimwa. Chimiro chemakemikari cheCMC chinoratidzwa nemapoka e-carboxymethyl (-CH2-COOH) akasungirirwa kumusana we cellulose. Iyo dhigirii yekutsiva (DS) yeCMC inoreva huwandu hwemapoka ecarboxymethyl aripo pane anhydroglucose unit (AGU) ye cellulose musana. Iyo DS yeCMC inogona kubva pa0.2 kusvika 1.5, ine yakakwirira DS kukosha inoratidza dhigirii repamusoro rekutsiva.

HPMC zvakare iri mumvura-soluble polymer iyo inotorwa kubva ku cellulose. Nekudaro, kusiyana neCMC, HPMC inogadziridzwa nehydroxypropyl uye methyl mapoka. Mapoka ehydroxypropyl (-OCH2CHOHCH3) akasungirirwa kumapoka ehydroxyl paseri peselulosi, nepo mapoka emethyl (-CH3) akasungirirwa kumapoka ehydroxypropyl. Iyo dhigirii yekutsiva yeHPMC inoreva huwandu hwehydroxypropyl uye methyl mapoka aripo paAGU yecellulose musana. Iyo DS yeHPMC inogona kubva pa0.1 kusvika 3.0, ine yakakwirira DS kukosha inoratidza dhigirii repamusoro rekutsiva.

2. Properties

CMC neHPMC vane zvivakwa zvakasiyana zvinoita kuti ive yakakodzera kune akasiyana maapplication. Zvimwe zvezvinhu zvakakosha zveCMC neHPMC zvakanyorwa pazasi:

a. Solubility: CMC inonyungudika zvakanyanya mumvura uye inoumba zvakajeka, zvinotapira mhinduro. HPMC zvakare yakanyungudika zvakanyanya mumvura, asi mhinduro dzinogona kunge dziine turbid zvichienderana nehuwandu hwekutsiva.

b. Rheology: CMC ndeye pseudoplastic zvinhu, zvinoreva kuti inoratidza kuveura kutetepa maitiro. Izvi zvinoreva kuti viscosity yeCMC inodzikira sezvo shear rate inowedzera. HPMC, kune rumwe rutivi, iNewtonian material, zvinoreva kuti viscosity yayo inoramba iripo pasinei neshear rate.

c. Mafirimu-ekugadzira zvimiro: CMC ine yakanaka yekugadzira firimu zvimiro, izvo zvinoita kuti ive yakakodzera kushandiswa mukukoira uye mafirimu. HPMC zvakare ine mafirimu-ekugadzira zvimiro, asi iwo mafirimu anogona kunge asina brittle uye ari nyore kupaza.

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

3. Uses

CMC uye HPMC inoshandiswa mumhando dzakasiyana dzekushandisa mumaindasitiri ezvekudya, emishonga, uye ega ega. Mamwe makiyi ekushandisa kweCMC neHPMC akanyorwa pazasi:

a. Indasitiri yechikafu: CMC inowanzoshandiswa seyakakora, inosimbisa, uye emulsifier muzvigadzirwa zvekudya zvakaita seaizikirimu, mapfekero esaladhi, 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: CMC inoshandiswa sebhainda, disintegrant, uye piritsi rekuvhara mumiriri mukugadzira mishonga. HPMC inoshandiswawo sebhainda, disintegrant, uye piritsi rekuvhara mumiriri mukugadzira mishonga.
