Ni irihe tandukaniro riri hagati ya HEC na MHEC?

HEC na MHEC ni ubwoko bubiri bwibikoresho bya polimeri bishingiye kuri selile bikoreshwa mubikorwa bitandukanye, birimo kubyimbye, stabilisateur, na emulisiferi mubicuruzwa byibiribwa, ndetse no mubikoresho bya farumasi no kwisiga. Itandukaniro nyamukuru hagati yibi byombi nuko HEC ari hydroxyethyl selulose, naho MHEC ni methyl hydroxyethyl selile.

HEC ni polymer yamazi ashonga ikomoka kuri selile, mubisanzwe polysaccharide iboneka mubihingwa. Igizwe numurongo umwe wa molekile ya glucose hamwe na hydroxyethyl itsinda ryometse kumpera ya buri molekile. HEC selulose ikoreshwa nkibyimbye, stabilisateur, na emulisiferi mubicuruzwa byibiribwa, ndetse no mubikoresho bya farumasi no kwisiga. Irakoreshwa kandi mugukora impapuro no gucapa, ndetse no mugukora ibifatika hamwe.

MHEC ni uburyo bwahinduwe bwa selile ya HEC aho hydroxyethyl itsinda ryasimbujwe itsinda rya methyl. Ihinduka ryongera hydrophobicity ya polymer, bigatuma irwanya ibintu byoroshye amazi. MHEC ikoreshwa mubikorwa bitandukanye, harimo nkibibyimbye, stabilisateur, na emulisiferi mubicuruzwa byibiribwa, ndetse no mubikoresho bya farumasi no kwisiga. Irakoreshwa kandi mu gukora impapuro no gucapa, ndetse no mu gukora ibifatika no gutwikira.

Muri make, itandukaniro nyamukuru hagati ya selile ya HEC na MHEC nuko HEC ari hydroxyethyl selulose, naho MHEC ni methyl hydroxyethyl selile. Ibikoresho byombi bikoreshwa mubikorwa bitandukanye, harimo kubyimbye, stabilisateur, na emulisiferi mubicuruzwa byibiribwa, ndetse no mubikoresho bya farumasi no kwisiga.
