Ndeupi musiyano uripo pakati peHEC neMHEC?

HEC neMHEC marudzi maviri e-cellulose-based polymers zvinhu zvinoshandiswa mune zvakasiyana-siyana zvekushandisa, zvinosanganisira semakobvu, stabilizers, uye emulsifiers muzvigadzirwa zvekudya, pamwe chete nemishonga yemishonga uye cosmetic. Musiyano mukuru pakati pezviviri ndewekuti HEC ihydroxyethyl cellulose, nepo MHEC iri methyl hydroxyethyl cellulose.

HEC ipolymer inonyungudika mumvura inotorwa kubva ku cellulose, polysaccharide inowanzoitika inowanikwa mumiti. Inoumbwa nemutsara weketani yemamorekuru eglucose neboka rehydroxyethyl rakasungirirwa kumagumo emorekuru rimwe nerimwe. HEC cellulose inoshandiswa seyakakora, stabilizer, uye emulsifier muzvigadzirwa zvechikafu, pamwe nemishonga uye zvizorwa. Inoshandiswawo mukugadzira mapepa uye kudhinda, pamwe nekugadzira zvinonamira uye machira.

MHEC inzira yakagadziridzwa yeHEC cellulose umo boka re hydroxyethyl rinotsiviwa neboka re methyl. Uku kugadziridzwa kunowedzera hydrophobicity yepolymer, ichiita kuti ive yakasimba kune inonyungudika mvura. MHEC inoshandiswa mumhando dzakasiyana siyana dzekushandisa, kusanganisira seyakakora, stabilizer, uye emulsifier muzvigadzirwa zvechikafu, pamwe nemishonga uye zvizorwa zvigadzirwa. Inoshandiswawo mukugadzira mapepa uye kudhinda, pamwe nekugadzira zvinonamira uye machira.

Muchidimbu, musiyano mukuru pakati peHEC cellulose neMHEC ndeyekuti HEC ihydroxyethyl cellulose, nepo MHEC iri methyl hydroxyethyl cellulose. Zvese zviri zviviri zvinoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira semakobvu, anosimbisa, uye emulsifiers muzvigadzirwa zvechikafu, pamwe nemishonga uye zvizorwa zvigadzirwa.
