Kedu ihe eji eme hypromellose?
Hypromellose, nke a makwaara dị ka hydroxypropyl methylcellulose (HPMC), bụ polymer synthetic nke sitere na cellulose. A na-eme ya site na imezi cellulose eke eke enwetara site na osisi pulp ma ọ bụ eriri owu site na usoro a maara dị ka etherification n'ụzọ kemịkal. N'ime usoro a, a na-emeso eriri cellulose na ngwakọta nke propylene oxide na methyl chloride, nke na-eduga na mgbakwunye nke hydroxypropyl na methyl na molecules cellulose.
Ngwaahịa a na-esi na ya pụta bụ polymer na-agbaze mmiri nke a na-eji na ngwa dị iche iche, gụnyere ọgwụ, ihe ịchọ mma, ngwaahịa nri, na ihe mgbakwunye nri. Hypromellose dị n'ọkwa dị iche iche, na-enwekwa ịdị arọ molekụla dị iche iche na ogo nnọchi anya, dabere n'iji ya eme ihe.
N'ozuzu, a na-ewere hypromellose dị ka ihe dị mma ma na-anabata nke ọma mgbe ejiri ya dịka ntụziaka. A na-ejikarị ya eme ihe dị ka onye na-ekpuchi ihe, onye na-eme ka ọ dị arọ, na onye na-eme ka ọ dị ike n'ọtụtụ ngwaahịa ma jiri ya kpọrọ ihe maka ike ya iji meziwanye nkwụsi ike ngwaahịa, ịbawanye viscosity, na ịkwalite arụmọrụ ngwaahịa.
