Hydroxypropyl methyl cellulose VS methyl cellulose

1. hydroxypropyl methyl celluloseỌ bụrụ na mmiri oyi agbaze, mmiri ọkụ ga-enwe nsogbu. Mana okpomọkụ ya na-agbaze n'ime mmiri ọkụ dị elu karịa nke methyl cellulose. A na-emekwa ka methyl cellulose na-agbaze n'ime mmiri oyi ka mma nke ukwuu.

2. Ọbara hydroxypropyl methyl cellulose nwere njikọ na ibu molekul ya, ibu molekul buru ibu bụkwa viscosity dị elu. Okpomọkụ ga-emetụtakwa viscosity ya, okpomọkụ na-abawanye, viscosity na-ebelata. Agbanyeghị, viscosity nke okpomọkụ dị elu dị ala karịa nke methyl cellulose. Ngwọta ahụ kwụsiri ike mgbe echekwara ya na okpomọkụ ụlọ.

3. Hydroxypropyl methyl cellulose kwụsiri ike na acid na alkali, mmiri mmiri ya na-adịkwa mma nke ukwuu n'ogo pH = 2 ~ 12. Caustic soda na mmiri lime enweghị mmetụta dị ukwuu na ihe onwunwe ya, mana alkali nwere ike ime ka ọsọ mgbaze ya dịkwuo ngwa ngwa ma melite viscosity nke pin ahụ. Hydroxypropyl methyl cellulose nwere nkwụsi ike na nnu izugbe, mana mgbe njupụta nke mmiri nnu dị elu, viscosity nke mmiri hydroxypropyl methyl cellulose na-abawanye.

4. Njide mmiri nke hydroxypropyl methyl cellulose dabere na ọnụọgụ mgbakwunye ya, viscosity, wdg. Ọnụego nchekwa mmiri n'okpuru otu ọnụọgụ mgbakwunye ahụ dị elu karịa nke methyl cellulose.

5. Nrapado nke hydroxypropyl methyl cellulose na owuwu ngwa agha dị elu karịa nke methyl cellulose.

6. hydroxypropyl methyl cellulosenwere nguzogide enzyme ka mma karịa methyl cellulose, ohere nke mmebi enzymatic na mmiri dị ala karịa methyl cellulose.
