Hydroxypropyl methylcellulose (HPMC) bụ ether cellulose na-abụghị ionic nke a na-ejikarị eme ihe n'ụdị ncha, ọkachasị n'ịkwalite arụmọrụ ncha.
1. Mmetụta dị arọ
HPMC na-enwe mmetụta dị nro nke ọma. Ịtinye HPMC na usoro ncha nwere ike ime ka viscosity nke ncha na-etolite ma mepụta usoro colloidal kwụsiri ike. Mmetụta a na-ebuwanye ibu nwere ike ọ bụghị nanị imeziwanye ọdịdị na mmetụta nke nchacha ahụ, kamakwa igbochi ihe ndị na-arụ ọrụ na-eme ka ọ ghara imebi ma ọ bụ na-asọpụta, si otú ahụ na-edobe ịdị n'otu na nkwụsi ike nke nchacha.
2. Nkwụsi ike nkwusioru
HPMC nwere ike imeziwanye nkwụsi ike nkwusioru nke ihe nchacha. Usoro nchacha na-enwekarị ụmụ irighiri ihe, dị ka enzymes, ihe ịcha ọcha, wdg, nke na-adịkarị mfe ịgbaze n'oge nchekwa. HPMC nwere ike n'ụzọ dị irè gbochie sedimentation nke ahụ site na ịba ụba viscosity nke usoro na akpụ a netwọk Ọdịdị, si otú huu nkwụsi ike nke ncha n'oge nchekwa na ojiji, na n'ịhụ na edo nkesa na-aga n'ihu ọrụ nke nọ n'ọrụ Efrata.
3. Solubilization na dispersibility
HPMC nwere ezigbo solubilization na dispersibility, nke nwere ike inyere mmiri na-adịghị edozi ihe na-arụ ọrụ na-eme ka ọ dị mma na-agbasasị na usoro ncha. Dịka ọmụmaatụ, ihe ndị na-esi ísì ụtọ na ihe ndị na-edozi ahụ dị n'ime ụfọdụ ncha nwere ike igosi adịghị ike na mmiri n'ihi adịghị ike ha. Mmetụta solubilization nke HPMC nwere ike ime ka ihe ndị a na-adịghị edozi ahụ gbasasịa nke ọma, si otú ahụ na-emeziwanye mmetụta nke ncha.
4. Lubricating na mmetụta nchebe
HPMC nwere mmetụta mmanụ mmanye ụfọdụ, nke nwere ike ibelata esemokwu n'etiti eriri akwa n'oge ịsacha ma zere mmebi akwa. Tụkwasị na nke ahụ, HPMC nwekwara ike ịmepụta ihe nkiri nchebe n'elu ákwà ahụ, belata nkwụsị na ịda mbà n'obi n'oge ịsacha, na ịgbatị ndụ ọrụ nke ákwà ahụ. N'otu oge ahụ, ihe nkiri nchebe a nwekwara ike ịrụ ọrụ mgbochi na-adịghị mma, na-egbochi ntụpọ ka ọ ghara ịbanye na akwa a na-asacha ọzọ.
5. Mgbochi nrụpụta mmetụta
N'oge usoro ịsa ahụ, ngwakọta nke unyi na nchacha nwere ike ịdoghachi na akwa ákwà, na-eme ka ọ ghara ịsa ahụ adịghị mma. HPMC nwere ike ịmepụta sistemu colloidal kwụsiri ike na ncha iji gbochie nchịkọta na redeposition nke unyi, si otú ahụ na-emeziwanye mmetụta nhicha nke ncha. Mmetụta mgbochi a na-eme ka ọ dị mkpa maka ịnọgide na-adị ọcha nke akwa ákwà, karịsịa mgbe ọtụtụ ịsachara.
6. Okpomọkụ na nnabata pH
HPMC na-egosi nkwụsi ike dị mma n'okpuru ọnọdụ okpomọkụ dị iche iche na pH, karịsịa n'okpuru ọnọdụ alkaline, arụmọrụ ya ka dị mma. Nke a na-enye HPMC ohere ịrụ ọrụ na gburugburu ebe ịsa ahụ dị iche iche, na-emetụtaghị ọnọdụ okpomọkụ na pH, si otú ahụ na-eme ka ọ dị irè nke ncha. Karịsịa na ngalaba ịsacha ụlọ ọrụ mmepụta ihe, nkwụsi ike a nke HPMC na-eme ka ọ bụrụ ihe mgbakwunye dị mma.
7. Biodegradaability na gburugburu ebe obibi enyi
HPMC nwere ezi biodegradability na ọ dịghị njọ na gburugburu ebe obibi, nke na-eme ka ọ na-amụba uru na nke oge a ncha usoro. N'ihe gbasara ihe nchebe gburugburu ebe obibi na-esiwanye ike, HPMC, dị ka ihe mgbakwunye enyi na gburugburu ebe obibi, nwere ike ibelata mmetụta ọjọọ na gburugburu ebe obibi ma mezuo ihe achọrọ maka mmepe na-adịgide adịgide.
8. Mmetụta mmekọrịta
HPMC nwere ike imekọrịta ya na mgbakwunye ndị ọzọ iji kwalite arụmọrụ ncha nke ncha. Dịka ọmụmaatụ, enwere ike iji HPMC yana nkwadebe enzyme iji kwalite ọrụ na nkwụsi ike nke enzymes ma melite mmetụta mwepụ nke ntụpọ isi ike. Na mgbakwunye, HPMC nwekwara ike melite arụmọrụ nke surfactants, na-eme ka ha nwee ike ịrụ ọrụ nke ọma na mmetọ.
HPMC nwere uru dị ukwuu n'ịkwalite arụmọrụ nke ncha. Ọ na-eme ka arụmọrụ nke ndị na-asa ákwà na-eme ka ọ dịkwuo mma site na ịgbatị, na-eme ka ihe kwụsịtụrụ, ịgbasa na ịgbasa, mmanụ mma na ichekwa, mgbochi nkwụghachi, na nkwụsi ike n'okpuru ọnọdụ dị iche iche. N'otu oge ahụ, ịdị mma gburugburu ebe obibi nke HPMC na biodegradaability na-emekwa ka ọ bụrụ nhọrọ dị mma na nhazi ncha ọgbara ọhụrụ. Site na mmepe na-aga n'ihu nke ahịa ncha na-abawanye ụba nke ndị na-azụ ahịa maka ngwaahịa dị elu na nke na-emetụta gburugburu ebe obibi, atụmanya ngwa nke HPMC na nchacha ga-abawanye.
