Ni irihe tandukaniro riri hagati ya HPMC na HEMC?
HPMC (Hydroxypropyl Methylcellulose) na HEMC (Hydroxyethyl Methylcellulose) byombi bikomoka kuri selile ikoreshwa nkibibyimbye, ibifunga, hamwe na emulisiferi mubicuruzwa bitandukanye. Byombi bikomoka kuri selile, polyisikaride isanzwe iboneka mu bimera.
Itandukaniro nyamukuru hagati ya HPMC na HEMC ni ubwoko bwa hydroxypropyl na hydroxyethyl matsinda afatanye na molekile ya selile. HPMC ifite hydroxypropyl matsinda ifatanye na molekile ya selile, mugihe HEMC ifite hydroxyethyl matsinda. Iri tandukaniro muburyo bwa hydroxypropyl na hydroxyethyl matsinda bigira ingaruka kumiterere yibikomoka kuri selile ebyiri.
HPMC irashonga cyane mumazi akonje kurusha HEMC, kandi irwanya ihindagurika ryubushyuhe. Ifite ubukonje burenze HEMC, kandi irwanya aside na alkali. Irwanya kandi kwangirika kwa mikorobe. HPMC ikoreshwa mubicuruzwa bitandukanye, birimo ibiryo, imiti, hamwe no kwisiga.
HEMC ntishobora gushonga mumazi akonje kurusha HPMC, kandi ntishobora kwihanganira ihindagurika ryubushyuhe. Ifite ubukonje buke ugereranije na HPMC, kandi ntishobora kurwanya aside na alkali. Ntabwo irwanya kandi kwangirika kwa mikorobe. HEMC ikoreshwa mubicuruzwa bitandukanye, birimo ibiryo, imiti, no kwisiga.
Muri make, HPMC na HEMC byombi bikomoka kuri selile ikoreshwa nkibibyimbye, binders, na emulisiferi mubicuruzwa bitandukanye. Itandukaniro nyamukuru hagati yibi byombi ni ubwoko bwa hydroxypropyl na hydroxyethyl matsinda ifatanye na molekile ya selile. HPMC ifite hydroxypropyl matsinda ifatanye na molekile ya selile, mugihe HEMC ifite hydroxyethyl matsinda. Iri tandukaniro muburyo bwa hydroxypropyl na hydroxyethyl matsinda bigira ingaruka kumiterere yibikomoka kuri selile ebyiri.
