Hydroxypropyl methylcellulose (HPMC) inoshandiswa zvakanyanya cellulose ether inozivikanwa nekunaka kwayo kukora zvinhu.Inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira ekuvaka, emishonga, chikafu uye kutarisirwa kwevanhu.Mubepa rino, isu tinotarisa pakukora kweHPMC uye nekuongorora zvinhu zvinokanganisa maitiro ayo ekukora.
Iyo yekukora meshini yeHPMC ndeye:
Iko kukora mhedzisiro yeHPMC kunonzi kune yakasarudzika mamorekuru chimiro.Iyo HPMC morekuru ine musana wemaketani e cellulose ane hydroxypropyl uye methyl mapoka akasungirirwa.Kana HPMC yakapararira mumvura kana zvimwe zvinonyungudutsa, maketani e cellulose anotora mvura nekuzvimba, zvichikonzera kuumbwa kweiyo 3D network chimiro.Iyi network inobata iyo solvent uye inowedzera viscosity kana kupararira kwemhinduro.
Zvinhu zvinokanganisa mhedzisiro yekukora:
Concentration: Iko kusungirirwa kweHPMC mukuumbwa kunoita basa rakakosha mukukora kwayo.Sezvo kusungirirwa kunowedzera, mamwe mamorekuru eHPMC anopindirana, zvichikonzera kukwidziridzwa viscosity uye kukora.
Molecular uremu: Iyo molecular huremu hweHPMC inokanganisa kukora kwayo.Huremu hwemamorekuru huremu HPMC kazhinji inoratidza huremu hwakasimba kana uchienzaniswa neakadzika mamorekuru uremu mamakisi.
Tembiricha: Kupisa kunogona kukanganisa maitiro ekukora eHPMC.
Iyo pH: Iyo pH yemushonga inogona kukanganisa kukora kweHPMC
Shear Rate: Kuveura kweshear, kana chiyero icho chigadziriswa chinokonzerwa ne mechanical stress, chinogona kukanganisa maitiro ekukora eHPMC. shear rates, senge panguva yekukurudzira kana kushandiswa, viscosity inogona kuderera nekuda kwekugera kuputsa chimiro chakaumbwa neHPMC.
Zvishandiso zveiyo Thickened HPMC:
Iko kukora mhedzisiro yeHPMC inoita kuti ive yakakosha yekuwedzera mune akawanda maapplication.Mamwe maapplication akajairika anosanganisira:
Kuvaka: HPMC inoshandiswa mune zvakasimirirwa zvinhu zvakaita sedhaka uye mataira anonamira kuti avandudze kushanda kwawo, kuchengetedza mvura uye sag kuramba.
Pharmaceuticals: HPMC inoshandiswa seyakakora mumuromo kumiswa, ophthalmic mhinduro uye topical gels, ichipa kuenderana kunodiwa uye kunatsiridza kuendesa zvinodhaka.
Chikafu & Zvinwiwa: HPMC inoshandiswa mune zvakasiyana siyana zvechikafu zvigadzirwa senge sosi, mapfekero uye madhiri ekuwedzera magadzirirwo, kugadzikana uye muromo kunzwa.
Kuzvichengeta Pachedu uye Zvekuzora: HPMC inowana zvikumbiro muzvigadzirwa zvekuchengetedza munhu, zvinosanganisira makirimu, mafuta ekuzora uye magadzirirwo ekuchengeta bvudzi, seanokora, anosimbisa uye anogadzira firimu.
Hydroxypropyl methylcellulose (HPMC) inoratidzira yakakosha kukora zvivakwa nekuda kweiyo yakasarudzika mamorekuru chimiro uye kudyidzana nemvura.Kunzwisisa zvinhu zvinopesvedzera kukora kweHPMC, senge kumisikidza, kurema kwema molecular, tembiricha, pH, uye shear rate, kwakakosha pakugadzira zvigadzirwa zvine viscosity inodiwa uye kuenderana.. akasiyana maindasitiri, achipa yakawedzera mashandiro uye hunhu hwechigadzirwa hwakagadziridzwa.
