Kodi pali kusiyana kotani pakati pa HEC ndi MHEC?

HEC ndi MHEC ndi mitundu iwiri ya ma polima opangidwa ndi cellulose omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo thickeners, stabilizers, ndi emulsifiers mu zakudya, komanso mankhwala ndi zodzoladzola. Kusiyana kwakukulu pakati pa awiriwa ndikuti HEC ndi hydroxyethyl cellulose, pamene MHEC ndi methyl hydroxyethyl cellulose.

HEC ndi polima yosungunuka m'madzi yomwe imachokera ku cellulose, polysaccharide yopezeka mwachilengedwe yomwe imapezeka muzomera. Amapangidwa ndi mzere wozungulira wa mamolekyu a shuga okhala ndi gulu la hydroxyethyl lomwe limamangiriridwa kumapeto kwa molekyulu iliyonse. HEC cellulose imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier muzakudya, komanso muzamankhwala ndi zodzikongoletsera. Amagwiritsidwanso ntchito popanga mapepala ndi kusindikiza, komanso popanga zomatira ndi zokutira.

MHEC ndi mawonekedwe osinthidwa a HEC cellulose momwe gulu la hydroxyethyl limasinthidwa ndi gulu la methyl. Kusintha kumeneku kumawonjezera hydrophobicity ya polima, ndikupangitsa kuti ikhale yosamva zinthu zosungunuka m'madzi. MHEC imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza monga thickener, stabilizer, ndi emulsifier muzakudya, komanso muzamankhwala ndi zodzoladzola. Amagwiritsidwanso ntchito popanga mapepala ndi kusindikiza, komanso popanga zomatira ndi zokutira.

Mwachidule, kusiyana kwakukulu pakati pa HEC cellulose ndi MHEC ndikuti HEC ndi hydroxyethyl cellulose, pamene MHEC ndi methyl hydroxyethyl cellulose. Zipangizo zonse ziwirizi zimagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza monga zokhuthala, zokhazikika, ndi zopangira ma emulsifiers muzakudya, komanso muzamankhwala ndi zodzikongoletsera.
