Misiyano pakati pehydroxyprusterl starch uye hydroxyprusll methyl cellulose

Hydroxyprusyl Starch uye HydroxyPropyl Methyl Celler CellerPolose. Nepo vachigovana zvakafanana, ivo vane mutsauko wakasiyana maererano nemakemikari chimiro, zvivakwa, uye zvinoshandiswa. Heano mutsauko mukuru pakati pehydroxypruppropyl starch uye hpmc:

Chemical dhizaini:

1. Hydroxyprupropyl starch:
   • Hydroxyprusyl starch in starch yakagadziriswa nekuburitsa hydroxypropropyl mapoka pane iyo starch morekuru.
   • Starch ndeye polysaccharide yakaumbwa neye glucose zvikamu zvakabatana pamwe neGlycosicIC zvisungo. Hydroxypruslation inosanganisira kutsiva kwehydroxyl (-OOOH) mapoka mune starch morekuru ne hydroxyprupyl (-ch2chohch3) mapoka.
2. Hydroxyprupyl methyl cellulose (HPMC):
   • HPMC chinhu chakagadziridzwa cellulose ether chakawanikwa nekuunza zvese hydroxypruppropyl uye methyl mapoka kune iyo cellulose molecule.
   • Cellulose is a polysaccharide yakaumbwa neyechikamu chakabatanidzwa pamwechete ne β (1 → 4) Glycosiic Zvisungo. Hydroxyprospropylation inozivisa hydroxyprupyl (-ch2chohch3) mapoka, nepo methylation inosuma methyl (-ch3) mapoka kune cellulose backbone.

Zvivakwa:

1. Solubility:
   • Hydroxyprupropyl starch inowanzo nyura mumvura inopisa asi inogona kuratidza kushoma solubility mumvura inotonhora.
   • HPMC inonyungudika mumvura inotonhora uye inopisa, inogadzira yakajeka, viscous mhinduro. Iyo solubility yeHPMC inoenderana neiyo degree rekutsiva (DS) uye iyo molecular uremu hwe polymer.
2. Viscosity:
   • Hydroxyprupyl Starch inogona kuratidza zvivakwa-zvinowedzera-zvinowedzera zvivakwa, asi viscosity yayo kazhinji yakaderera ichienzaniswa neHPMC.
   • HPMC inozivikanwa nekuda kwayo kwakanyanya kunaka uye viscossity-inogadzirisa zvinhu. Iyo viscosity yeHPMC Solutions inogona kugadziridzwa nekusiyana polymer yekusimbisa, DS, uye molecular uremu.

Zvishandiso:

1. Chikafu neMishonga:
   • Hydroxyprosyl starch inowanzo shandiswa seanotenderedza, stabilizer, uye ganda mumiririri mune zvigadzirwa zvekudya senge soups, sosi, uye madhayeti. Inogona zvakare kushandiswa mumishonga yemishonga.
   • HPMC inozoshandiswa zvakanyanya mune chikafu, mishonga yemishonga, uye macometicals, uye macometics seanoti, emulsifier, stabilizer, firimu raimbova, uye rakadzorwa-kuburitswa. Zvinowanzowanikwa mune zvigadzirwa zvakaita semapiritsi, mafuta, uye zvinhu zvekutarisira pachako.
2. Kuvaka uye Zvivakwa zvekuvaka:
   • HPMC inoshandiswa zvakanyanya muindasitiri yekuvaka seyakawedzera muzvikamu zveSementi-based sile adhesives, mota, inopa, uye mapuranga, uye plasters. Inopa kuchengetwa kwemvura, kushanda, kuderedza, uye nekuvandudza kuita mune izvi zvekushandisa.

Mhedziso:

Nepo mese hydroxypruppropyl starch uye hpmc yakagadziridzwa polysacchararides ine zvakafanana masangano, ivo vane zvikamu zvemakemikari zvemakemikari, zvivakwa, uye zvinoshandiswa. Hydroxyprupyl starch inonyanya kushandiswa mune zvekudya uye pharmaceutical application, nepo Hpmc ichizotarisisa pakudya, mishonga, cosmeticals, cosmetics, uye zvigadzirwa zvekuvaka, uye zvekuvaka, uye zvekuvakira zvinhu. Iyo sarudzo pakati pehydroxyprusterl starch uye hpmc zvinoenderana nezvinodiwa chaizvo zvekushandisa chinangwa.
