5. Tolite na-etolite HPMC
Site na itinye oge nke hpmc molekuly na ịzụlite usoro ọgwụgwọ HPMC ọhụrụ, enwere ike ịzikwuo arụmọrụ viscosict. Dịka ọmụmaatụ, zụlite Hpmc derivatives na ike nguzogide siri ike na nguzogide electrolyte nwere ike iji mezuo mkpa nke usoro nhicha ngwaahịa dị mgbagwoju anya. Na mgbakwunye, mmepe nke gburugburu ebe obibi na biodegradideble hpmc merivatives ga-enyere aka mee ka arụmọrụ gburugburu nke ihicha nhicha ma soro usoro nke kemịkalụ dị ugbu a.
Dị ka onye na-ahụ maka ihe dị mkpa dị mkpa na viscositser, HPMC nwere atụmanya ngwa dị na ngwaahịa nhicha. Agbanyeghị, n'ihi ezi uche dị na ihe ndị metụtara gburugburu ebe obibi dị ka okpomọkụ na ike ionic, ihe ịma aka dị na njikwa viscosity HPMC ka dị. Site na iji usoro nke hpmc, na-eji usoro ihe omimi, na-agbakwunye solings, na-agbakwunye solings ma ọ bụ kwụrụ ọtọ, na nchịkwa nzọpụta nke Hpmc na ngwaahịa ọcha nwere ike ime ka ọ dị mma. N'otu oge ahụ, na mmepe nke usoro dị ọcha hpmc ọhụrụ, njikwa viscosise ngwaahịa n'ọdịnihu ga-arụ ọrụ nke ọma ma kwụsie ike, na-emewanye arụmọrụ na ahụmịhe nke ngwaahịa nhicha.
