HPMC Hypromellose

Hydroxypropyl Methylcellulose(HPMC), bụ ngwakọta kemịkalụ na-agbanwe agbanwe nwere usoro [C6H7O2 (OH) 3-mn (OCH3) m (OCH2CH (OH) CH3) n] x, ebe m na-anọchi anya ogo nke nnọchi methoxy yana n na-anọchi anya ogo hydroxypropoxy. nnọchi. A na-enweta ya site na cellulose, polymer eke sitere na mgbidi cell nke osisi. HPMC enweghị isi, enweghị ụtọ, na anaghị egbu egbu. Ọ nwere ihe dị iche iche physicochemical dị ka solubility na mmiri, thermal gelation properties, na ike ịmepụta ihe nkiri, na-eme ka a na-eji ya eme ihe n'ọtụtụ ụlọ ọrụ.

N'ime ụlọ ọrụ ọgwụ, a na-eji HPMC eme ihe n'ọtụtụ ebe dị ka ihe na-akpali akpali-ihe emepụtara n'akụkụ ihe na-arụ ọrụ nke ọgwụ, maka ebumnuche nke nkwụsi ike ogologo oge, na-ebuli usoro siri ike nke nwere ihe ndị nwere ike na-arụ ọrụ na obere obere (nke a na-ezokarị aka na ya). dị ka ihe ndochi, diluent, ma ọ bụ ihe na-ebu), ma ọ bụ iji kwalite absorption ma ọ bụ solubility. Capsules HPMC bụ ihe ọzọ na capsules gelatin maka ndị anaghị eri anụ, a na-ejikwa ya na usoro mwepụta a na-achịkwa, na-enye ohere maka mwepụta ọgwụ ngwa ngwa ka oge na-aga. Ihe ngwọta HPMC nwekwara ike ije ozi dị ka viscolyzers iji mee ka viscosity nke ngwọta anya, melite bioadherence, na ịgbatị oge obibi ọgwụ n'elu anya.

N'ime ụlọ ọrụ nri, a na-amata HPMC dị ka ihe mgbakwunye nri dị nchebe (E464) ma na-arụ ọrụ dị iche iche dị ka emulsifier, onye na-eme ka ọ dị arọ, na stabilizer. A na-eji ya na-emepụta ihe oriri dị iche iche iji meziwanye udidi, na-ejigide mmiri, na ịmepụta ihe nkiri oriri. Ngwongwo gelation thermal nke HPMC bara uru karịsịa na ngwa chọrọ gelling na okpomọkụ dị iche iche, dị ka nri anaghị eri anụ na nri anụ anaghị eri anụ ebe ọ nwere ike dochie gelatin. HPMC na-enyekwa aka na ndụ nchekwa na ịdị mma nke ngwaahịa esitere, sauces na desserts site na ịchịkwa crystallization na mmiri mmiri.

Ụlọ ọrụ ihe owuwu na-erite uru site na HPMC n'ichepụta ihe ụlọ. Ngwa ya gụnyere ime ihe dị ka onye na-ekekọta ihe na-ejigide mmiri na ngwa agha, plasta, na mkpuchi, na-eme ka arụ ọrụ dịkwuo mma, ibelata ojiji mmiri, na ịgbatị oge oghe - oge a na-eji ihe eji eme ihe. HPMC na-akwalite njirimara nke usoro simenti dabeere, na-enye mma mmachi, mgbasa, na iguzogide sagging.

N'ime ihe ịchọ mma na ụlọ ọrụ nlekọta onwe onye, ​​HPMC na-eje ozi dị ka onye na-emepụta ihe nkiri, emulsifier, na rheology modifier na ngwaahịa dị ka lotions, creams, na gels ntutu.
