Ni irihe tandukaniro riri hagati ya CMC na MC?

CMC na MC byombi bikomoka kuri selile bikoreshwa cyane mubyimbye, guhambira, hamwe na stabilisateur mubikorwa bitandukanye, harimo ibiryo, imiti, ninganda zita kubantu. Ariko, hariho itandukaniro hagati yibi byombi bikwiye kwitonderwa.

CMC, cyangwa Carboxymethyl Cellulose, ni polymer-amazi ashonga ikomoka kuri selile. Yakozwe mugukora selile hamwe na sodium chloroacetate no guhindura amwe mumatsinda ya hydroxyl kuri selile mumatsinda ya carboxymethyl. CMC ikoreshwa cyane mubicuruzwa byibiribwa, nkibicuruzwa bitetse, ibikomoka ku mata, hamwe nisosi, ndetse no mubicuruzwa byita ku muntu na farumasi.

MC, cyangwa Methyl Cellulose, nayo ni polymer-eruble polymer ikomoka kuri selile. Yakozwe mugukora selile hamwe na methyl chloride no guhindura amwe mumatsinda ya hydroxyl kuri selile mumatsinda ya methyl ether. MC ikoreshwa nkibibyimbye, binder, na emulifisiyeri mubikorwa bitandukanye, harimo mubicuruzwa byibiribwa, nk'isosi, imyambarire, hamwe nubutayu bwakonje, no mubikoresho bya farumasi nibicuruzwa byawe bwite.

Itandukaniro rimwe ryingenzi hagati ya CMC na MC nibiranga gukemura. CMC iroroshye gushonga mumazi kuruta MC, kandi irashobora gukora igisubizo gisobanutse neza, kiboneka mumitekerereze mike. MC kurundi ruhande, mubisanzwe bisaba kwibanda cyane hamwe na / cyangwa gushyushya gushonga byuzuye mumazi, kandi ibisubizo byayo birashobora kuba byinshi cyangwa ibicu.

Irindi tandukaniro ni imyitwarire yabo mubihe bitandukanye bya pH. CMC ihagaze neza mubihe bya acide kandi irashobora kwihanganira urwego rugari rwa pH kurenza MC, rushobora kumeneka no gutakaza imiterere yabubyimbye mubidukikije.

Byombi CMC na MC nibikomoka kuri selile ya selile ifite ibintu byinshi byingirakamaro mubikorwa bitandukanye. Guhitamo uwo ukoresha bizaterwa nibisabwa byihariye bya porogaramu n'ibiranga imikorere yifuzwa.
