Hydroxypropyl methylcellulose (HPMC) bụ ihe dị mkpa mmiri-soluble nonionic cellulose ether na ezi ndim, gelling, bonding, film-akpụ, lubricating, emulsifying na suspending ọrụ, n'ihi ya, ọ na-ọtụtụ ebe na-ewu ụlọ, pharmaceuticals, nri, ntecha na ndị ọzọ ubi. .
Usoro siri ike nke hydroxypropyl methylcellulose
The ndim mmetụta nke HPMC tumadi si ya molekụla Ọdịdị. Chain molekụla HPMC nwere hydroxyl na methyl dị iche iche, nke nwere ike ịmepụta njikọ hydrogen na ụmụ irighiri mmiri, si otú a na-egbochi mmegharị n'etiti ụmụ irighiri mmiri na ịbawanye viscosity nke ngwọta. Mgbe HPMC gbazere n'ime mmiri, yinye molekụla ya na-apụta na mmiri ma na-emekọrịta ihe na mkpụrụ ndụ mmiri iji mepụta usoro netwọkụ, si otú ahụ na-abawanye viscosity nke ngwọta. The thickening ike nke HPMC na-emetụtakwa ihe ndị dị ka ogo nke nnọchi ya, molekụla arọ na itinye uche.
Ngwa nke hydroxypropyl methylcellulose n'ime ihe owuwu ụlọ
N'ihe owuwu ụlọ, a na-ejikarị HPMC eme ihe na ngwaahịa ndị dị ka ngwa ngwa ciment, ihe ndị dabeere na gypsum na mkpuchi dị ka ihe na-ekpuchi mmiri na mmiri. Mmetụta ya na-eme ka ọ sie ike nwere ike imeziwanye arụmọrụ ihe owuwu nke ihe ma mee ka arụ ọrụ mgbochi ya dịkwuo elu, si otú a na-eme ka usoro ihe owuwu ahụ dịkwuo mma. Dịka ọmụmaatụ, na ciment mortar, mgbakwunye nke HPMC nwere ike ime ka viscosity nke ngwa agha ahụ dịkwuo elu ma gbochie ngwa agha ahụ ka ọ ghara ịda mbà mgbe a na-arụ ya n'elu elu kwụ ọtọ. Ọ nwekwara ike melite njigide mmiri nke ngwa agha ahụ ma gbochie ngwa agha ahụ ka ọ ghara ihichapụ ngwa ngwa, si otú ahụ na-eme ka ike na ịdịte aka nke ngwa agha ahụ dịkwuo mma.
Ngwa nke Hydroxypropyl Methylcellulose n'ọhịa ọgwụ
N'ebe a na-emepụta ọgwụ, a na-eji HPMC eme ihe na mbadamba nkume, capsules, gels, ophthalmic preparations na ọgwụ ndị ọzọ dị ka thickener, ihe nkiri mbụ na nrapado. Ya ezi ndim mmetụta nwere ike melite rheological Njirimara nke ọgwụ ma melite nkwụsi ike na bioavailability nke ọgwụ. Dịka ọmụmaatụ, na nkwadebe ophthalmic, HPMC nwere ike iji dị ka mmanu na thickener, na ezigbo mmetụta ya nwere ike ịgbatị oge obibi nke ọgwụ ahụ n'elu anya anya, si otú ahụ na-eme ka ọ dị mma nke ọgwụ ahụ.
Ngwa nke Hydroxypropyl Methylcellulose na nri
N'ụlọ ọrụ nri, a na-ejikarị HPMC eme ihe na nri dị ka ngwaahịa mmiri ara ehi, jelii, ihe ọ beụ ,ụ na ngwaahịa esiri esi dị ka thickener, emulsifier na stabilizer. Mmetụta ya siri ike nwere ike melite uto na udidi nke nri, ma mee ka viscosity na nkwụsi ike nke nri dịkwuo elu. Dịka ọmụmaatụ, na ngwaahịa mmiri ara ehi, HPMC nwere ike ịbawanye viscosity nke ngwaahịa ma gbochie mmiri ozuzo whey, si otú ahụ meziwanye uto na nkwụsi ike nke ngwaahịa ahụ.
Ngwa nke Hydroxypropyl Methylcellulose na ịchọ mma
N'ihe gbasara ịchọ mma, a na-eji HPMC eme ihe na ngwaahịa ndị dị ka lotions, creams, shampoos na conditioners dị ka thickener, emulsifier na stabilizer. Mmetụta ya siri ike nwere ike melite udidi na nkwụsi ike nke ihe ịchọ mma, ma melite mmetụta ojiji na ahụmịhe nke ndị ahịa. Dịka ọmụmaatụ, na lotions na creams, mgbakwunye HPMC nwere ike ime ka viscosity nke ngwaahịa ahụ dịkwuo elu, na-eme ka ọ dị mfe itinye na ịmịnye ya, ma na-eme ka mmetụta dị nro nke ngwaahịa ahụ dịkwuo mma.
A na-eji Hydroxypropyl Methylcellulose mee ihe n'ọtụtụ ebe n'ime ihe owuwu ụlọ, ọgwụ, nri na ihe ịchọ mma n'ihi njirimara ya dị oke mma. Usoro ya na-eme ka ọ sie ike bụ iji mee ka viscosity nke ngwọta ya dịkwuo elu site n'ịme njikọ hydrogen na ụmụ irighiri mmiri, na-egbochi mmegharị nke mkpụrụ ndụ mmiri. Ugbo dị iche iche nwere ngwa dị iche iche chọrọ maka HPMC, mana ọrụ ya bụ ịkwalite viscosity na nkwụsi ike nke ngwaahịa ahụ. Site na mmepe nke sayensị na teknụzụ yana mmepe teknụzụ ngwa na-aga n'ihu, atụmanya ngwa nke HPMC ga-abawanye.
