Musiyano pakati peHPMC neMHEC

HPMC (Hydroxypropyl Methylcellulose) uye MHEC (Methylhydroxyethylcellulose) ndiwo marudzi maviri ezvinobuda muselulosi anoshandiswa mukushandiswa kwakasiyana-siyana. Ose ari maviri mapolymers-akavakirwa zvinhu zvinoshandiswa kukora, kusunga, uye kudzikamisa zvigadzirwa. Ose ari maviri anoshandiswa zvakanyanya mumaindasitiri ezvekudya, emishonga, uye zvekuzora.

Musiyano mukuru pakati peHPMC neMhec imhando yecellulose inoshandiswa kugadzira. HPMC inogadzirwa kubva kuhydroxypropyl methylcellulose, uku Mhec ichigadzirwa kubva kumethylhydroxyethylcellulose. HPMC imhando yakanatswa zvakanyanya ye cellulose, nepo Mhec iri fomu rakanatswa.

HPMC ivhu chena, risinganhuhwi, uye risingaravi rinonyungudika mumvura inotonhora. Inoshandiswa seyakakora mumiriri, emulsifier, stabilizer, uye inomisa mumiriri mune zvakasiyana zvigadzirwa. Inoshandiswawo kuwedzera viscosity yemhinduro uye kuvandudza magadzirirwo ezvigadzirwa. Inowanzoshandiswa muzvigadzirwa zvekudya zvakadai seaizikirimu, sosi, uye mapfekero.

Ukuwo Mhec ihupfu huchena, husinganhuhwi, uye husina kunaka hunonyungudika mumvura inopisa kana inotonhora. Inoshandiswa seyakakora mumiriri, emulsifier, stabilizer, uye inomisa mumiriri mune zvakasiyana zvigadzirwa. Inoshandiswawo kuwedzera viscosity yemhinduro uye kuvandudza magadzirirwo ezvigadzirwa. Inowanzoshandiswa muzvigadzirwa zvekudya zvakadai seaizikirimu, sosi, uye mapfekero.

Panyaya yekushanda, HPMC inowanzoonekwa seine simba kupfuura Mhec. Yakagadzikana uye ine viscosity yakakwirira kupfuura Mhec. Iyo zvakare inopokana nekuchinja kwekushisa uye pH. Pamusoro pezvo, HPMC ine hupenyu hwakareba kupfuura Mhec.

Panyaya yemutengo, HPMC inowanzo dhura kupfuura Mhec. Izvi zvinodaro nekuti HPMC imhando yakanatswa zvakanyanya ye cellulose uye saka inodhura kugadzira.

Pakazere, HPMC neMhec ese ari maviri anoshandiswa zvakanyanya mumaindasitiri ezvekudya, emishonga, uye zvekuzora. Iwo ese ari maviri anoshandiswa seanokora maajenti, emulsifiers, stabilizers, uye ekumisa maajenti mune zvakasiyana zvigadzirwa. HPMC inowanzonzi inoshanda kudarika Mhec, asi zvakare inodhura.
