Hydroxypropylmethylcellulose (HPMC) ipolymer inonyungudika mumvura inotorwa kubva muselulosi yechisikigo uye inoshandiswa zvakanyanya mumaindasitiri mazhinji nekuda kwekugona kwayo kuburitsa huwandu hwemaviscosity mune aqueous mhinduro. HPMC ine dzakasiyana siyana dzekushandisa mumishonga, chikafu uye cosmetic maindasitiri. Viscosity ndiyo yakakosha hunhu hweHPMC mhinduro inokanganisa mashandiro avo mumashandisirwo aya.
Zvinhu zvinokanganisa viscosity:
1. Kuisa pfungwa: Iko kusungirirwa kweHPMC mumhinduro kunoenderana zvakananga ne viscosity yemhinduro. Sezvo huwandu hweHPMC hunowedzera, viscosity yemushonga inowedzera sezvo macheni epolymer anowedzera kubatwa. Nekudaro, yakanyanya kuwanda inogona kukonzera yakaoma uye gel-senge mhinduro, iyo inogona kunge isingafadzi kune mamwe maapplication.
2. Molecular weight: The molecular weight of HPMC chinhu chinokosha chinokanganisa viscosity yemhinduro. Sezvo huremu hwemamorekuru hweHPMC huchiwedzera, viscosity yemhinduro inowedzerawo nekuda kwekuwedzera kubatwa kwemaketani epolymer. HPMC ine huremu hwepamusoro-soro ine cheni dzakareba, zvichiita kuti pave nemhinduro yakawanda ye viscous.
3. Tembiricha: Iyo viscosity yeHPMC mhinduro inokanganisawo tembiricha. Sezvo tembiricha yemhinduro inowedzera, viscosity yemushonga inoderera. Kudzikira kweviscosity kunokonzerwa nekudzikira kwemasimba epakati pakati pemaketani epolymer, zvichikonzera kusapindirana uye kuwedzera kwemvura.
4. pH kukosha: Iyo pH kukosha kwemhinduro ichakanganisawo viscosity yeHPMC mhinduro. pH kukosha kunze kweiyo 5.5-8 renji inogona kukonzera kudzikira kweviscosity nekuda kwekuchinja mukunyungudika uye kuchaja kweHPMC polymer.
5. Salinity: Iyo salinity kana ionic simba remhinduro inokanganisawo viscosity yeHPMC mhinduro. Kuwedzera munyu kunokanganisa kupindirana kweHPMC polymer cheni, zvichikonzera kudzikira kwemhinduro viscosity.
6. Mamiriro ekuveura: Mamiriro ekuveura iyo iyo HPMC mhinduro inoratidzwa ichakanganisawo viscosity yemhinduro. Mamiriro ekucheka anogona kukonzera kuderera kwechinguva muviscosity, senge panguva yekusanganiswa kana kupomba kwemhinduro. Kamwe mamiriro ekuveura akabviswa, viscosity inokurumidza kudzokera kune yakadzikama.
mukupedzisa:
Iko viscosity yeHPMC aqueous solutions inobatwa nemhando dzakasiyana-siyana dzinoda kutariswa paunenge uchigadzira chigadzirwa. Concentration, molecular weight, tembiricha, pH, salinity, uye shear mamiriro ndiwo akanyanya kukosha anokanganisa viscosity yeHPMC mhinduro. Kunzwisisa zvinhu izvi kunogona kubatsira vagadziri kukwidziridza viscosity yeHPMC mhinduro kune chaiwo maapplication. Viscosity chimiro chakakosha cheHPMC mhinduro sezvo ichigona kuona mashandiro uye kugadzikana kweHPMC-yakavakirwa zvigadzirwa.
