Lub rheology thiab compatibility ntawm hydroxypropyl methylcellulose (HPMC) thiab hydroxypropyl starch (HPS) complexes plays lub luag hauj lwm tseem ceeb nyob rau hauv ntau yam industries, xws li tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, thiab kev tsim kho.Nkag siab txog kev sib cuam tshuam ntawm ob lub polymers no yog qhov tseem ceeb rau kev ua kom zoo dua lawv cov kev ua tau zoo thiab tsim cov khoom tshiab.Daim ntawv no yog tsom mus tshawb txog cov khoom rheological thiab kev sib raug zoo ntawm HPMC/HPS complex.
Rheological Properties:
Rheology yog kev kawm txog cov ntaub ntawv deform thiab ntws raws li kev cuam tshuam ntawm sab nraud quab yuam.Nyob rau hauv cov ntaub ntawv ntawm HPMC / HPS complex, rheological zog txiav txim lub viscosity, gelation cwj pwm, thiab tag nrho cov ndlwg zog ntawm lub polymer sib tov.Cov cwj pwm rheological ntawm cov complex tuaj yeem cuam tshuam los ntawm cov khoom xws li polymer concentration, molecular hnyav, kub, thiab shear npaum li cas.
Compatibility ntawm HPMC thiab HPS:
Kev sib raug zoo ntawm HPMC thiab HPS yog qhov tseem ceeb los xyuas kom muaj kev ruaj ntseg complexes nrog cov khoom tsim nyog.Compatibility yog hais txog lub peev xwm ntawm ob los yog ntau tshaj polymers sib tov thiab tsim ib homogeneous system yam tsis muaj theem sib cais los yog poob ntawm kev ua tau zoo..
Cov yam ntxwv cuam tshuam rau rheology thiab compatibility:
Polymer ratio: Qhov piv ntawm HPMC rau HPS hauv ib qho nyuaj tuaj yeem cuam tshuam rau nws cov khoom rheological thiab kev sib raug zoo ..
Molecular hnyav: Qhov hnyav molecular ntawm HPMC thiab HPS cuam tshuam rau rheology thiab compatibility ntawm complex.
Kub: Qhov kub ntawm lub complex yog npaj thiab kuaj cuam tshuam rau nws tus cwj pwm rheological.
Shear Rate: Tus nqi shear siv thaum kuaj lossis ua tiav tuaj yeem cuam tshuam cov khoom rheological ntawm HPMC / HPS complex.Ntau dua shear tus nqi tuaj yeem ua rau tus cwj pwm shear-thinning, qhov twg cov viscosity txo qis nrog nce shear npaum li cas.
Daim ntawv thov:
Lub rheology thiab compatibility ntawm HPMC / HPS complex muaj qhov cuam tshuam rau ntau yam kev lag luam. Raws li ib tug thickening neeg sawv cev, stabilizer, los yog emulsifier.Hauv kev tsim cov ntaub ntawv, cov complexes tuaj yeem txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov cemented systems.
Rheology thiab compatibility ntawm HPMC / HPS complexes yog ib qho tseem ceeb rau optimizing lawv kev ua tau zoo rau ntau yam kev siv.. To taub cov teebmeem ntawm yam xws li polymer ratio, molecular yuag, kub thiab shear tus nqi yog ib qho tseem ceeb rau tsim formulations uas xav tau rheological zog.. Kev tshawb fawb ntxiv. thiab kev loj hlob hauv cheeb tsam no tuaj yeem ua rau kev tsim cov khoom tshiab nrog kev ua haujlwm zoo dua qub thiab txhim kho kev ua haujlwm hauv ntau qhov kev lag luam.
