Qhov sib txawv tseem ceeb ntawm thixotropic thiab pseudoplastic yog qhov viscosity ntawm thixotropic kua txo qis thaum siv lub zog thaum lub viscosity ntawm cov kua pseudoplastic nce thaum siv lub zog.
Cov kua dej yog cov kua lossis cov roj gaseous uas muaj viscosity. Peb tuaj yeem faib cov kua dej ua ob hom raws li viscosity li thixotropic thiab rheopectic kua. Ob qho no yog cov kua dej uas tsis yog Newtonian. Ntxiv rau qhov ntawd, muaj ob hom kua dej li Bingham thiab pseudoplastic kua, raws li cov khoom. Txawm li cas los xij, kab lus no feem ntau tsom rau qhov sib txawv ntawm thixotropic thiab pseudoplastic kua.
Thixotropic yog dab tsi?
Thixotropic kua yog kua lossis roj uas nws viscosity txo qis thaum siv kev ntxhov siab nyob rau lub sijhawm paub. Yog li, nws tuaj yeem txhais tau tias yog lub sijhawm nyob ntawm tus cwj pwm pseudoplastic. Hauv qhov sib piv, tus cwj pwm ntawm cov kua dej rheopectic tuaj yeem piav qhia raws li tus cwj pwm dilatant raws sijhawm. Tsis tas li ntawd, cov kua dej thixotropic qhia txog tus cwj pwm tsis zoo-linear kev ntxhov siab thiab. Yog li ntawd, ntev lub kua mus nyob rau hauv shear kev nyuaj siab, txo lub viscosity ntawm cov kua yuav ua. Hauv lwm lo lus, cov kua dej no siv sijhawm kom tau txais nws cov viscosity equilibrium thaum muaj kev hloov pauv ntawm tus nqi txiav tawm.
Qee yam piv txwv ntawm cov kua dej thixotropic suav nrog cytoplasm ntawm cov hlwb, cov kua dej synovial, qee hom zib ntab, qee hom av nplaum, cov nplaum nplaum hauv cov khoom siv hluav taws xob, xov-xauv kua, gelatin, xanthan gum, thiab lwm yam.
YPseudoplastic yog dab tsi?
Pseduoplastic kua yog kua lossis roj uas nws viscosity nce thaum siv lub zog. Cov kua dej sib txawv rau pseudoplastic yog Bingham kua. Nws yog cov kua dej nyob ntawm lub sijhawm vim tias qhov kev ntxhov siab shear siv rau cov kua dej thaum lub sijhawm tshwj xeeb raug coj los txiav txim qhov kev hloov pauv hauv viscosity.
Daim duab 01: Ketchup yog ib qho piv txwv ntawm Pseudoplastic Fluid
Ib qho piv txwv ntawm cov tshuaj pseudoplastic yog kev ncua ntawm pob kws hauv dej. Ntawm no, qhov concentration ntawm cornstarch yuav tsum sib npaug zos rau cov concentration ntawm dej. Thaum tsis muaj zog siv, qhov kev ncua no coj zoo li dej. Tab sis, thaum shear stress yog siv rau ntawm cov kua, nws solidifies. Lwm cov piv txwv xws li xim thiab ketchup.
Qhov txawv ntawm Thixotropic thiab Pseudoplastic yog dab tsi?
Thixotropic thiab pseudoplastic yog ob hom kua dej uas tuaj yeem cais raws li tus cwj pwm ntawm cov kua dej thaum siv lub zog. Qhov sib txawv tseem ceeb ntawm thixotropic thiab pseudoplastic yog qhov viscosity ntawm thixotropic kua txo qis thaum siv lub zog, qhov viscosity ntawm cov kua pseudoplastic nce thaum siv lub zog.
Qee yam piv txwv ntawm cov kua dej thixotropic muaj xws li cytoplasm ntawm cov hlwb, cov kua dej synovial, qee hom zib ntab, qee hom av nplaum, cov nplaum nplaum hauv cov khoom siv hluav taws xob, xov-xauv kua, gelatin, xanthan gum, thiab lwm yam. Pseudoplastic kua muaj xws li ketchup, xim, pob kws nyob rau hauv dej ncua kev kawm ntawv, thiab lwm yam
Cov lus hauv qab no qhia txog qhov sib txawv ntawm thixotropic thiab pseudoplastic kua.
Summary – Thixotropic vs Pseudoplastic
Nyob rau hauv luv luv, thixotropic thiab pseudoplastic yog ob hom kua uas tuaj yeem categorized raws li tus cwj pwm ntawm cov kua dej thaum siv lub zog. Qhov sib txawv tseem ceeb ntawm thixotropic thiab pseudoplastic yog qhov viscosity ntawm thixotropic kua txo qis thaum siv lub zog, qhov viscosity ntawm cov kua pseudoplastic nce thaum siv lub zog.
