Ni irihe tandukaniro riri hagati ya hydroxyyerlceellylcellse na cmc?

Hydroxyyeryl selile (HEC) na Carboxymethyl selile (CMC) ni kose ibikomokaho, bikoreshwa mubyimbye, bigakoreshwa no guhagarara, ariko porogaramu zabo ziratandukanye. bitandukanye.

Hydroxyyeryl selile iraboneka mu gufata sodium hydroxide na etyl hydroxide. Ifite ikibazo cyo kwikunda hamwe nibintu byimitungo kandi bikoreshwa cyane mubikota, kwisiga hamwe nimyiteguro ya farumasi. Ikintu nyamukuru ni uguhaza kwayo gukomeye guhinduka nubushobozi bwayo bwo gukomeza guhagarara muri rusange ph.

Ku rundi ruhande Carboxymethylcellse, kurundi ruhande, bikozwe mu gufata ikarigo hamwe na aside ya chloroacetike kandi irimo amatsinda ya carboxyl, ayitanga visoxy, akayitanga visone nyinshi nubushobozi bwo gukora geles. CMC ikunze gukoreshwa mumirima y'ibiryo, imiti, no kwisiga, cyane cyane nkumubyimba na stilizer mubiryo.

Hec na CMC bafite itandukaniro rikomeye mumiterere yimiti, kwikekura, viscosiya nibisabwa. Nibihe bikoresho byo guhitamo biterwa no gukoresha ibikenewe nibisabwa.
