Musiyano pakati peHPMC vs methylcellulose

HPMC (Hydroxypropyl methylcellulose) uye methylcellulose ese ari maviri anowanzo shandiswa mumaindasitiri ezvekudya, emishonga, uye ega ega seanokora, anosimbisa, emulsifiers, uye anosunga maajenti. Kunyange vachigovana zvimwe zvakafanana, pane mimwe misiyano pakati peHPMC nemethylcellulose:

1. Chimiro chemakemikari: Zvose HPMC uye methylcellulose zvakatorwa kubva ku cellulose, polysaccharide inowanzoitika. HPMC is a modified cellulose, uko mamwe emapoka ehydroxyl ari pa cellulose morekuru akatsiviwa nemapoka ehydroxypropyl. Methylcellulose zvakare yakagadziridzwa cellulose, uko mamwe emapoka ehydroxyl ari pa cellulose morekuru akatsiviwa nemapoka emethyl.
2. Solubility: HPMC inonyanya kunyungudika mumvura kupfuura methylcellulose, izvo zvinoita kuti zvive nyore kunyunguduka uye kushandisa mukuumbwa.
3. Viscosity: HPMC ine viscosity yakakwirira kupfuura methylcellulose, zvinoreva kuti ine zviri nani kukora zvivakwa uye inogona kugadzira kusimba kwakakura mukuumbwa.
4. Gelation: Methylcellulose inokwanisa kugadzira gel kana ichipisa uye yatonhodzwa, nepo HPMC isina iyi pfuma.
5. Mutengo: HPMC inowanzodhura kupfuura methylcellulose.

Pakazere, sarudzo pakati peHPMC nemethylcellulose inotsamira pane chaiyo application uye inodiwa zvimiro zvekugadzira. HPMC inogona kusarudzwa nekuda kwekunyungudika kwayo uye kusimba kwayo, nepo methylcellulose inogona kufarirwa pakugona kwayo kugadzira gels.
