Hydroxypropyl methyl cellulose

Hydroxypropyl methyl cellulose (HPMC) bụ eriri polymer eke sitere na usoro nhazi kemịkal na nkwadebe nke ether cellulose na-abụghị ionic.
DB usoro HPMC bụ a gbanwetụrụ cellulose ether ngwaahịa nke bụ ihe soluble na mmiri na mepụtara pụrụ iche maka imeziwanye arụmọrụ nke akọrọ agwakọta ngwa agha mgbe elu ọgwụgwọ.

Njirimara ngwaahịa: ☆ Mmụba agụụ mmiri

Viscosity nke ngwọta metụtara okpomọkụ. Ka okpomọkụ nke ngwọta na-abawanye, viscosity na-amalite ibelata ruo mgbe e guzobere gel, na mmụba na okpomọkụ ga-eme ka ọkpụkpụ. Usoro a nwere ike ịtụgharị.

Mmekọrịta dị n'etiti viscosity na njide mmiri, nke dị elu nke viscosity, ka mma na-ejigide mmiri. N'ikwu okwu n'ozuzu, a na-agbanwe ike mmiri nke cellulose dị ka ọnọdụ okpomọkụ si dị, na mmụba nke okpomọkụ ga-eduga ná mbelata nke ikike ijide mmiri.
