HPMC hydroxypropyl methylcelluloserave rimwe remapiritsi makuru emishonga munyika nekunze kwenyika, nekuti HPMC ine zvakanakira zvisina mamwe mapiritsi.
1. Kunyungudika kwemvura
Inonyungudika mumvura inotonhora iri pasi pe40 ℃ kana 70% ethanol, uye hainyungudike mumvura inopisa iri pamusoro pe60 ℃, asi inogona kusanganiswa nejeli.
2. Kusashanda kwemakemikari
HPMC imhando ye non-ionic cellulose ether. Mushonga wayo hauna ionic charge uye hausangani nemetal salts kana ionic organic compounds. Saka, zvimwe zvinhu zvinobatsira hazvisangani nayo panguva yekugadzirira.
3. Kugadzikana
Haina kugadzikana zvakanyanya kune acid nealkali, uye inogona kuchengetwa kwenguva yakareba pakati pe pH 3 ~ 11, uye viscosity yayo haina shanduko yakajeka. Mhinduro yemvura yeHPMC ine simba rekudzivirira ganda uye inogona kuchengetedza kugadzikana kwakanaka kwe viscosity panguva yekuchengetwa kwenguva refu. Mishonga inoshandisaHPMCdzine kugadzikana kwemhando yepamusoro pane dzinoshandisa zvinhu zvechinyakare (zvakaita se dextrin, starch, nezvimwewo).
4. Kugadziriswa kwe viscosity
Zvibereko zvakasiyana zveHPMC zvinogona kusanganiswa muzvikamu zvakasiyana, uye viscosity yayo inogona kuchinja zvichienderana nemutemo wakati, uye ine hukama hwakanaka hwemutsara, saka inogona kusarudzwa zvichienderana nekudiwa. 2.5 Kusagadzikana kwemetabolism HPMC hainyudzwe kana kugayiwa mumuviri, uye haipe macalorie, saka chinhu chakachengeteka chemishonga. .
5. Kuchengetedzwa
Zvinowanzoonekwa kutiHPMChaisi chinhu chine chepfu uye hachitsamwisi.
HPMC yemhando yemishonga chinhu chakakosha pakugadzira mishonga inoburitswa kwenguva refu uye inodzorwa. Imushonga unobatsira pakutsvaga nekusimudzira mishonga unotsigirwa nehurumende, uye unoenderana negwara rekusimudzira rinotsigirwa nemutemo wenyika weindasitiri. HPMC yemhando yemishonga ndiyo chinhu chikuru chekugadzira makapisi eHPMC, ichitora anopfuura 90% yezvinhu zveHPMC. Makapisi emiti anogadzirwa ane zvakanakira zvekuchengetedza uye hutsanana, kushanda zvakanyanya, hapana njodzi yekubatana, uye kugadzikana kwakanyanya, izvo zvinoenderana nezvinodiwa nevatengi. Zvinodiwa zvekuchengetedza uye hutsanana hwechikafu nemishonga ndeimwe yemishonga yakakosha uye zvigadzirwa zvakanaka zvekutsiva makapisi egelatin emhuka.
