Hydroxypropyl methylcellulose (HPMC) bụ cellulose ether nke a na-ejikarị eme ihe maka ihe na-eme ka ọ dị mma.A na-arụ ya n'ọrụ n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ihe owuwu, ụlọ ọgwụ, nri na nlekọta onwe onye.N'ime akwụkwọ a, anyị na-elekwasị anya na mmetụta nke HPMC siri ike ma nyochaa ihe ndị na-emetụta àgwà ya.
Usoro ịgbado ọkụ nke HPMC bụ:
A na-ekwu na ọ bụ nrụpụta nke HPMC na usoro ihe omimi ya pụrụ iche.Molecule HPMC nwere ọkpụkpụ azụ nke ụdọ cellulose nwere hydroxypropyl na methyl dị iche iche jikọtara ya.Mgbe HPMC na-agbasasị na mmiri ma ọ bụ ihe mgbaze ndị ọzọ, agbụ cellulose na-amịkọrọ mmiri ma zaa, na-eme ka e guzobe usoro netwọk 3D.Netwọk a na-ejide ihe mgbaze ma na-abawanye viscosity ma ọ bụ mgbasa nke ngwọta.
Ihe na-emetụta mmetụta nke thickening:
Ntụkwasị: Ntụkwasị nke HPMC na a usoro na-ekere òkè dị ịrịba ama na ya ndim mmetụta.Ka ntinye uche na-abawanye, ọtụtụ ụmụ irighiri ihe HPMC na-emekọrịta ihe, na-eduga n'inwe viscosity na ndi siri ike.
Arọ molekụla: Arọ molekụla nke HPMC na-emetụta njirimara ya.Ibu arọ molekụla dị elu HPMC na-egosipụtakarị mmetụta dị ike karịa ka akara ule dị ala.
Okpomọkụ: The okpomọkụ nwere ike imetụta ndị ndim omume nke HPMC.. N'ozuzu, ịba ụba okpomọkụ na-ebelata viscosity na ndim mmetụta nke HPMC ngwọta.
The pH: The pH nke ngwọta nwekwara ike imetụta ndim mmetụta nke HPMC.
Shear Rate: The shiee ọnụego, ma ọ bụ ọnụego nke ngwọta na-edo onwe ya n'ibu nrụgide, nwere ike imetụta ndị thickening omume nke HPMC. Ọnụọgụ shea, dị ka n'oge mkpali ma ọ bụ ngwa, viscosity nwere ike ibelata n'ihi shiee na-agbaji ihe owuwu nke HPMC hibere.
Ngwa nke HPMC gbara ọkpụrụkpụ:
Mmetụta siri ike nke HPMC na-eme ka ọ bụrụ ihe mgbakwunye bara uru n'ọtụtụ ngwa.Ụfọdụ ngwa a na-ahụkarị gụnyere:
Ihe owuwu: A na-eji HPMC na ihe simenti dị ka ngwa agha na nrapado tile iji meziwanye ọrụ ha, njide mmiri na nguzogide sag.
Pharmaceuticals: A na-eji HPMC n'ọrụ dị ka onye na-agba ume na nkwusioru ọnụ, ngwọta anya na gels dị n'elu, na-enye nkwụsi ike achọrọ na nkwalite nnyefe ọgwụ.
Nri na ihe ọṅụṅụ: A na-eji HPMC n'ụdị nri dị iche iche dị ka sauces, uwe na desserts iji kwalite udidi, nkwụsi ike na mmetụta ọnụ.
Nlekọta onwe onye na ihe ịchọ mma: HPMC na-achọta ngwa na ngwaahịa nlekọta onwe onye, gụnyere ude, lotions na usoro nlekọta ntutu isi, dị ka ihe na-agba agba, stabilizer na onye na-emepụta ihe nkiri.
Hydroxypropyl methylcellulose (HPMC) na-egosiputa ihe njiri mara nke ọma n'ihi usoro ihe omimi ya pụrụ iche na mmekọrịta ya na mmiri.Ịghọta ihe ndị na-emetụta mmetụta dị arọ nke HPMC, dị ka itinye uche, ịdị arọ molecular, okpomọkụ, pH, na shear rate, dị oké mkpa iji mepụta ngwaahịa na viscosity na nkwụsi ike nke achọrọ. ụdị ọrụ dịgasị iche iche, na-enye arụmọrụ emelitere yana njirimara ngwaahịa dị mma.
