Kedu ihe dị iche n'etiti HPMC na HEMC?

HPMC (Hydroxypropyl Methylcellulose) na HEMC (Hydroxyethyl Methylcellulose) bụ ma ihe nrụpụta cellulose nke a na-eji dị ka thickeners, binders, na emulsifiers na ngwaahịa dị iche iche. Ha abụọ sitere na cellulose, polysaccharide sitere n'okike dị na osisi.

Isi ihe dị iche n'etiti HPMC na HEMC bụ ụdị hydroxypropyl na hydroxyethyl dị iche iche na-ejikọta na cellulose molecule. HPMC nwere otu hydroxypropyl jikọtara na molekul cellulose, ebe HEMC nwere otu hydroxyethyl jikọtara. Ọdịiche a dị n'ụdị hydroxypropyl na otu hydroxyethyl na-emetụta njirimara nke usoro cellulose abụọ.

HPMC na-agbaze na mmiri oyi karịa HEMC, ọ na-eguzogidekwa mgbanwe okpomọkụ. Ọ nwere viscosity dị elu karịa HEMC, ọ na-eguzogidekwa acid na alkali. Ọ na-eguzogidekwa mmebi microbial. A na-eji HPMC n'ụdị ngwaahịa dị iche iche, gụnyere nri, ọgwụ na ihe ịchọ mma.

HEMC dị obere soluble na mmiri oyi karịa HPMC, ọ naghịkwa eguzogide mgbanwe okpomọkụ. Ọ nwere viscosity dị ala karịa HPMC, ọ naghịkwa eguzogide acid na alkali. Ọ dịkwa obere eguzogide mmebi microbial. A na-eji HEMC na ngwaahịa dị iche iche, gụnyere nri, ọgwụ na ihe ịchọ mma.

Na nchịkọta, HPMC na HEMC bụ ma cellulose mmepụta nke na-eji dị ka thickeners, binders, na emulsifiers n'ụdị dị iche iche nke ngwaahịa. Isi ihe dị iche n'etiti ha abụọ bụ ụdị hydroxypropyl na hydroxyethyl dị iche iche na-ejikọta na cellulose molecule. HPMC nwere otu hydroxypropyl jikọtara na molekul cellulose, ebe HEMC nwere otu hydroxyethyl jikọtara. Ọdịiche a dị n'ụdị hydroxypropyl na otu hydroxyethyl na-emetụta njirimara nke usoro cellulose abụọ.
