Ubwino wa HPMC ya mtundu wa mankhwala

HPMC hydroxypropyl methylcellulosechakhala chimodzi mwa zinthu zazikulu kwambiri zogwiritsira ntchito mankhwala m'dziko muno komanso kunja, chifukwa HPMC ili ndi ubwino womwe zinthu zina zogwiritsira ntchito mankhwala zilibe.

1. Kusungunuka kwa madzi

Imasungunuka m'madzi ozizira pansi pa 40 ℃ kapena 70% ethanol, ndipo kwenikweni siisungunuka m'madzi otentha pamwamba pa 60 ℃, koma imatha kusungunuka ndi gel.

2. Mankhwala osagwira ntchito

HPMC ndi mtundu wa ether ya cellulose yosakhala ionic. Yankho lake silikhala ndi mphamvu ya ionic ndipo siligwirizana ndi mchere wachitsulo kapena mankhwala a ionic organic. Chifukwa chake, zinthu zina zowonjezerera sizigwirizana nayo panthawi yokonzekera.

3. Kukhazikika

Ndi yokhazikika bwino ku asidi ndi alkali, ndipo imatha kusungidwa kwa nthawi yayitali pakati pa pH 3 ~ 11, ndipo kukhuthala kwake sikusintha kwenikweni. Yankho lamadzi la HPMC limakhala ndi mphamvu yotsutsana ndi chimfine ndipo limatha kusunga kukhuthala kwabwino pakusungidwa kwa nthawi yayitali. Zosakaniza zamankhwala zomwe zimagwiritsa ntchitoHPMCali ndi kukhazikika kwabwino kuposa omwe amagwiritsa ntchito zinthu zowonjezerera zachilengedwe (monga dextrin, starch, ndi zina zotero).

4. Kusintha kwa kukhuthala

Ma viscosity derivatives osiyanasiyana a HPMC amatha kusakanikirana mosiyanasiyana, ndipo viscosity yake imatha kusintha malinga ndi lamulo linalake, ndipo ili ndi ubale wabwino wa mzere, kotero imatha kusankhidwa malinga ndi kufunikira. 2.5 Kusakhazikika kwa kagayidwe kachakudya HPMC siimayamwa kapena kusinthidwa m'thupi, ndipo sipereka ma calories, kotero ndi chowonjezera chotetezeka cha mankhwala.

5. Chitetezo

Kawirikawiri amaonedwa kutiHPMCsi poizoni komanso siwopseza.

HPMC ya mankhwala ndi chinthu chofunikira kwambiri popanga mankhwala opangidwa nthawi zonse komanso olamulidwa. Ndi chinthu chowonjezera mankhwala chomwe chimathandizidwa ndi boma pa kafukufuku ndi chitukuko, ndipo chikugwirizana ndi njira yopangira yomwe ikuthandizidwa ndi mfundo za mafakitale za dzikolo. HPMC ya mankhwala ndi chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga makapisozi a zomera za HPMC, chomwe chimapanga zoposa 90% ya zinthu zopangira makapisozi a zomera za HPMC. Makapisozi a zomera opangidwa ali ndi ubwino wa chitetezo ndi ukhondo, kugwiritsidwa ntchito kwakukulu, palibe chiopsezo cha kuyanjana, komanso kukhazikika kwakukulu, zomwe zikugwirizana ndi zomwe ogula amayembekezera. Zofunikira za chitetezo ndi ukhondo wa chakudya ndi mankhwala ndi chimodzi mwazowonjezera zofunika komanso zinthu zabwino kwambiri zosinthira makapisozi a gelatin a nyama.
