Hydroxypropyl Methyl Cellulose (HPMC) Solubility na mmanya Isopropyl: Ntuziaka zuru oke
Hydroxypropyl Methyl Cellulose (HPMC) bụ polymer vasatail nke a na-ejikarị n'ụlọ ọrụ dị iche iche maka ihe ndị pụrụ iche.N'isiokwu a, anyị na-enyocha solubility nke HPMC na mmanya isopropyl (IPA), na-amụba àgwà ya na ihe mgbaze a na-emekarị.
Ịghọta HPMC:
HPMC bụ cellulose ether nke sitere na cellulose eke sitere na usoro mgbanwe kemịkalụ.A na-amata ya nke ọma maka ihe ndị na-agbaze mmiri na ihe nkiri, na-eme ka ọ bụrụ nhọrọ kachasị mma na ụlọ ọrụ dịka.ihe owuwu, ọgwụ, namkpuchis.
