Yambitsitsani:
HydroxypropylmethylElose (HPMC) ndi Hydroxyellulose (Hec) amagwiritsidwa ntchito zowonjezera pachakudya, zodzikongoletsera ndi mafakitale. Ma cellulose awa ali ndi chiyembekezo chothandiza kugwiritsa ntchito chifukwa cha kukhazikika kwawo kwa madzi apadera, kukhazikika kwamphamvu, ndi luso labwino kwambiri.
Kapangidwe ka 1.Chemical:
HPMC ndi polty wopanga kuchokera ku cellulose. Amapangidwa ndi kusinthana kwachilengedwe kwa cellulose powonjezera propylene oxide ndi methyl chloride. Hec nawonso mtundu wa cellulose, koma limapangidwa ndi cellulose wachilengedwe ndi ethylene oxide ndipo kenako amachiza ndi alkali.
2. Solubility:
Onse a HPMC ndi Hec ndi osungunuka madzi ndipo amatha kusungunuka m'madzi ozizira. Koma kusungunuka kwa Hec ndi kotsika kuposa HPMC. Izi zikutanthauza kuti HPMC ili ndi nthawi yopuma bwino ndipo itha kugwiritsidwa ntchito mosavuta pakupanga.
3. Makutu:
HPMC ndi HeC ili ndi mawonekedwe osiyanasiyana chifukwa cha zida zawo zamankhwala. Hec ali ndi kulemera kwambiri kwa zolemera komanso kapangidwe ka deper kuposa hpmc, yomwe imapereka mamasukidwe apamwamba. Chifukwa chake, hec nthawi zambiri imagwiritsidwa ntchito ngati thicker mu kapangidwe kake kamene kamafunikira mamasukidwe kwambiri, pomwe HPMC imagwiritsidwa ntchito popanga mapangidwe otsika.
4. Magwiridwe antchito afilimu:
Onse a HPMC ndi HeC ali ndi mphamvu zabwino kwambiri. Koma HPMC ili ndi kutentha kotsika ka mafilimu, komwe kumatanthauza kugwiritsidwa ntchito pa kutentha kochepa. Izi zimapangitsa kuti HPMC ikhale yoyenera kugwiritsa ntchito kapangidwe kake komwe kumafuna nthawi yopuma mwachangu komanso kutsatira bwino.
5. Kukhazikika:
HPMC ndi Hec ndizokhazikika pansi pa pH ndi kutentha. Komabe, Hec imakhudzidwa kwambiri ndi kusintha kwa pH kuposa hpmc. Izi zikutanthauza kuti Hec iyenera kugwiritsidwa ntchito ngati mitundu ya mankhunje 5 mpaka 10, pomwe HPMC itha kugwiritsidwa ntchito mu mtundu wa ph.
6. Ntchito:
Makhalidwe osiyanasiyana a hpmc ndi hec amawapangitsa kukhala oyenera mapulogalamu osiyanasiyana. Hec imagwiritsidwa ntchito ngati wothandizira wokulirapo ku zodzikongoletsera ndi ma prermacemical. Amagwiritsidwanso ntchito ngati chomangira ndi othandizira makanema pa piritsi. HPMC imagwiritsidwa ntchito ngati thicker, okhazikika, ndi othandizira mafilimu mu chakudya, mankhwala, komanso ma cosmekiti. Amagwiritsidwanso ntchito ngati wothandizirana ndi zakudya.
Pomaliza:
HPMC ndi Hec ndi zonse zochokera ku cellulose zomwe zimakhala ndi zida zapadera pazomwe zimayenera kugwiritsa ntchito njira zosiyanasiyana. Kuzindikira kusiyana pakati pa zowonjezera ziwirizi kungakuthandizeni kusankha yoyenera kwa chinsinsi chanu. Ponseponse, HPMC ndi Hec ndi zowonjezera zabwino komanso zowonjezera zomwe zimapereka maubwino ambiri pazakudya, zodzikongoletsera ndi mafakitale.
