Hydroxypropyl Methylcellulose (HPMC) bụ polymer multifunctional nke a na-ejikarị eme ihe na ọgwụ, nri, ịchọ mma na ụlọ ọrụ ihe owuwu. Ọ nwere ọmarịcha ịgba, imepụta ihe nkiri, nkwụsi ike na mma mmanye ma na-arụ ọrụ dị mkpa n'ọtụtụ usoro ngwaahịa. Viscosity nke HPMC bụ otu n'ime ihe ndị dị mkpa ma nwee mmetụta dị ukwuu na arụmọrụ ngwaahịa na ngwa.
1. Mmetụta dị arọ
A na-ekpebi viscosity nke HPMC tumadi site na ibu molekụla ya na ogo nke nnọchi (ụdị na ogo nke nnọchi). High viscosity HPMC nwere ike budata dịkwuo viscosity nke ngwọta, si otú na-egwu a ndim ọrụ na ọtụtụ formulations. Dịka ọmụmaatụ, n'ụlọ ọrụ nri, a na-ejikarị HPMC eme ihe dị ka ihe na-esi ísì ụtọ na ngwaahịa mmiri ara ehi, ihe ọṅụṅụ, sauces na ngwaahịa achịcha iji meziwanye uto na nkwụsi ike nke ngwaahịa ahụ. HPMC nwere viscosity dị elu nwere ike igbochi stratification mmiri nke ọma ma melite ngbanwe ngwaahịa.
2. Ntọhapụ a na-achịkwa
N'ime ụlọ ọrụ na-emepụta ọgwụ, a na-ejikarị HPMC eme ihe n'ụdị ọgwụ ntọhapụ a na-achịkwa. HPMC nwere viscosity dị elu nwere ike ịmepụta gel viscosity dị elu na mmiri, nke ji nwayọọ nwayọọ na-agbaze n'ime ahụ ma jiri nwayọọ nwayọọ na-ahapụ ọgwụ ọjọọ, na-enyere aka nweta ntọhapụ ọgwụ na-adịte aka. Dịka ọmụmaatụ, na mbadamba mbadamba na capsules agbatịpụrụ, viscosity nke HPMC nwere mmetụta kpọmkwem na ọnụego mwepụta ọgwụ. Ịhọrọ HPMC na viscosity kwesịrị ekwesị nwere ike ịhazigharị profaịlụ ntọhapụ ọgwụ dịka ọ dị mkpa, melite mmetụta ọgwụgwọ yana belata mmetụta.
3. Ihe na-emepụta ihe nkiri
HPMC nwere ọmarịcha ihe na-emepụta ihe nkiri, nke dị mkpa karịsịa n'ọtụtụ ngwa. HPMC dị elu nwere ike ịmepụta ihe nkiri siri ike na nke edo ma na-ejikarị dị ka ihe mkpuchi maka mbadamba ọgwụ iji chebe ihe ndị na-emepụta ọgwụ site na mmetụta nke ìhè, mmiri na oxygen na ịgbatị ndụ shelf nke ngwaahịa ahụ. Na mgbakwunye, na ihe ịchọ mma, HPMC nwere viscosity dị elu nwere ike iji ngwaahịa dị ka ihe mkpuchi ihu, gels na lotions iji nye mkpuchi dị mma na mmetụta moisturize.
4. Nkwụsi ike
HPMC nwere ezigbo nkwụsi ike kemịkalụ yana nkwụsi ike ọkụ na ngwọta mmiri. High viscosity HPMC nwere ike melite anụ ahụ kwụsie ike nke ngwaahịa na-egbochi urughuru mmezi na stratification. N'ime emulsions, nkwusioru na ngwọta colloidal, mmetụta na-agbapụta nke HPMC nwere ike melite nkwụsi ike nke usoro ahụ ma hụ na ngwaahịa ahụ na-anọgide na-edozi n'oge nchekwa na ojiji.
5. mmanu mmanu
High viscosity HPMC nwere ezigbo mmanu mmanu, nke dịkwa oke mkpa na ọtụtụ ụlọ ọrụ ngwa. Dịka ọmụmaatụ, na ụlọ ọrụ ihe owuwu ụlọ, a na-ejikarị HPMC eme ihe na ciment mortar na gypsum ngwaahịa dị ka mmanu na thickener iji melite arụmọrụ ihe owuwu na ike ọrụ nke ngwaahịa ahụ. Na mgbakwunye, na nhazi nri, HPMC viscosity dị elu nwere ike melite extensibility na viscoelasticity nke mgwakota agwa ma welie uto na udidi nke nri.
6. Nhọrọ viscosity
Na ngwa bara uru, ọ dị oke mkpa ịhọrọ HPMC na viscosity kwesịrị ekwesị. Viscosity nke dị oke elu nwere ike ime ka ngwọta ahụ sie ike ijikwa na njikwa, ebe viscosity nke dị oke ala nwere ike ọ gaghị enye mmetụta zuru oke na nkwụsịtụ. Ya mere, na ngwaahịa usoro imewe, ọ na-adịkarị mkpa ịhọrọ HPMC na kwesịrị ekwesị viscosity dị ka kpọmkwem ngwa chọrọ, na ebuli usoro site nnwale iji nweta kacha mma.
The viscosity nke HPMC nwere ịrịba mmetụta na ya ọrụ na arụmọrụ dị iche iche ngwaahịa formulations. Site n'ịhọrọ na ịhazigharị viscosity nke HPMC, ọtụtụ ọrụ dị ka ndina, ntọhapụ a na-achịkwa, mmepụta ihe nkiri, nkwụsi ike na mmanye nke ngwaahịa nwere ike nweta iji gboo mkpa nke ụlọ ọrụ na ngwa dị iche iche. N'ime ngwa bara uru, nghọta miri emi nke njirimara viscosity nke HPMC na nhọrọ ezi uche dị na ya na njikarịcha dabere na usoro achọrọ ga-enyere aka melite ogo ngwaahịa na asọmpi.
