Kedu ihe dị iche n'etiti HEC na MHEC?

HEC na MHEC bụ ụdị abụọ nke ihe ndị na-emepụta ihe na-emepụta cellulose nke a na-eji eme ihe n'ụdị dị iche iche, gụnyere dị ka ndị na-ekpo ọkụ, ndị na-eme ka ọkpụkpụ, na emulsifiers na ngwaahịa nri, yana na ngwaahịa ọgwụ na ihe ịchọ mma. Isi ihe dị iche n'etiti abụọ ahụ bụ na HEC bụ hydroxyethyl cellulose, ebe MHEC bụ methyl hydroxyethyl cellulose.

HEC bụ polymer soluble mmiri nke sitere na cellulose, polysaccharide sitere n'okike dị na osisi. Ihe mejupụtara ya bụ eriri ahịrị ahịrị nke molekul glucose nwere otu hydroxyethyl jikọtara na njedebe nke molekul ọ bụla. A na-eji HEC cellulose eme ihe dị ka onye na-agba ume, stabilizer, na emulsifier na ngwaahịa nri, yana na ngwaahịa ọgwụ na ihe ịchọ mma. A na-ejikwa ya na-ede akwụkwọ na ibipụta akwụkwọ, yana n'ịmepụta ihe nkedo na mkpuchi.

MHEC bụ ụdị mgbanwe HEC cellulose nke a na-eji otu methyl dochie otu hydroxyethyl. Mgbanwe a na-abawanye hydrophobicity nke polymer, na-eme ka ọ bụrụ ihe na-eguzogide ọgwụ na-edozi mmiri. A na-eji MHEC eme ihe n'ụdị dị iche iche, gụnyere dị ka onye na-agba agba, stabilizer, na emulsifier na ngwaahịa nri, yana na ngwaahịa ọgwụ na ihe ịchọ mma. A na-ejikwa ya na-ede akwụkwọ na ibipụta akwụkwọ, yana n'ịmepụta ihe nkedo na mkpuchi.

Na nchịkọta, isi ihe dị iche n'etiti HEC cellulose na MHEC bụ na HEC bụ hydroxyethyl cellulose, ebe MHEC bụ methyl hydroxyethyl cellulose. A na-eji ihe abụọ ahụ eme ihe n'ụdị ngwa dị iche iche, gụnyere dị ka ndị na-agba agba, stabilizers, na emulsifiers na ngwaahịa nri, nakwa dị ka ọgwụ na ihe ịchọ mma.
