Kodi ndi chiyani chomwe chimapangidwa ndi mankhwala a HPMC HyPromelwese?

HyPromellose, omwe amadziwikanso kuti hydroxypropyl meth methylcellulose (hpmc), ndi polty yopangidwa kuchokera ku cellulose. Amagwiritsidwa ntchito kwambiri mu mankhwala opangira mankhwala, chakudya ndi zodzikongoletsera monga kukula, emulsifier ndi binder. HPMC ndi chinthu chopanda poizoni ndi biodegrargrad, ndikupangitsa kukhala kotetezeka komanso kwachilengedwe.

1. Madzi osungunuka

HPMC imasungunuka m'madzi ndipo imapanga yankho lomveka bwino kapena pang'ono. Kusungunuka kwa HPMC kumadalira pa kalasi yake ya ma vidiyo, kulemera kwa maselo ndi kuchuluka kwa zolowa m'malo mwake. Makina apamwamba kwambiri komanso maselo olemera olemera amasungunuka kuposa magiredi otsika. Mlingo wa kuloweza kumatsimikizira kuchuluka kwa hydroxypyll ndi methyl magulu omwe amaphatikizidwa ndi msana wa HPMC Celluse. Kukwera kwambiri kwa cholowa m'malo, kutsitsa kwamadzi.

2. Kutengeka kwa mankhwala

HPMC imakhazikika mokhazikika ndipo sizikugwirizana ndi mankhwala okhazikika komanso ogwiritsa ntchito. Imalimbana ndi alkalis, ma acid acid ndi okhazikika ambiri. Komabe, HPMC imakhudzana ndi acid a acid ndi othandizira oxidi, omwe amachititsa kuwonongeka kwake ndikuwonongeka. Chifukwa chake, tikulimbikitsidwa kupewa kutulutsa HPMC ku Acid acid kapena othandizira oxidi.

HPMC ili ndi katundu wabwino kwambiri wamafilimu ndipo ndi woyenera piritsi lokutidwa ndi piritsi, kumasulidwa ndi kuwunika. Kanemayo wopangidwa ndi HPMC imasinthasintha, yowoneka bwino komanso yosalala. Kanemayo amalepheretsanso kuwonongeka kwa chophika cha piritsi kapena kapisozi.

Kutengera ndi kalasi yake, hpmc imapezeka kwambiri potenthedwa ndi madzi pamwamba pa kutentha kwina. Kutentha kwa mpweya kumayambira 50 ° C mpaka 90 ° C. Gel opangidwa ndi HPMC yasintha, kutanthauza kuti imasungunuka kubwerera kumadzi ozizira. Katunduyu amapangitsa kuti HPMC yoyenera igwiritsidwe ntchito pakutulutsa kovomerezeka, chifukwa mankhwalawa amatha kumasulidwa pamtunda wapadera.

5. Zachidziwikire zolengedwa

HPMC imawonetsa machitidwe a pseudoplastic, kutanthauza kuti ma viscction ake amachepetsa ndikuwonjezeka. Katunduyu amapangitsa kuti HPMC yoyenera igwiritsidwe ntchito ngati thickir ndi kusungunuka mu chakudya komanso kapangidwe ka zodzikongoletsera. HPMC imagwiritsidwanso ntchito ngati kuyimilira chifukwa cha machitidwe ake a thixotropic, zomwe zikutanthauza kuti ma viscy amachepetsa pansi pa kupsinjika kosalekeza.

HPMC ndi chinthu chosiyanasiyana komanso chotetezeka ndi zinthu zabwino zamankhwala. Kusungunuka kwamadzi, kukhazikika kwamadzi, kukhazikitsidwa kwamafilimu, katundu wa mawonekedwe a filimu, majerekalogication ndi nkhanza zanyengo zimapangitsa kuti ikhale chisankho chotchuka mu mafakitale osiyanasiyana. HPMC ilinso biodegradle komanso yosangalatsa, ndikupangitsa kuti ikhale chisankho chokhazikika.
