Hauv rheology, shear thinning yog qhov tsis yog-Newtonian tus cwj pwm ntawm cov kua dej uas nws cov viscosity txo qis hauv cov txheej txheem shear. Nws yog qee zaum suav hais tias yog ib qho piv txwv rau tus cwj pwm pseudoplastic, thiab feem ntau txhais tau tias tsis suav nrog cov teebmeem ntawm lub sijhawm, xws li thixotropy.
Yuav ua li cas thaum shear thinning?
Shear thinning yog qhov tshwm sim ntawm qee qhov tsis yog-Newtonian cov kua dej uas cov kua viscosity txo qis nrog nce kev ntxhov siab. Shear thickening yog qhov opposite phenomenon.
piv txwv ntawm shear thinning yog dab tsi?
Shear thinning fluids, tseem hu ua pseudo-plastics, yog ubiquitous nyob rau hauv industrial thiab lom cov txheej txheem. Cov piv txwv xws li ketchup, xim thiab ntshav. Tsis yog-Newtonian tus cwj pwm ntawm cov kua dej tuaj yeem tshwm sim los ntawm ntau yam, tag nrho cov ntawm lawv muaj feem xyuam rau cov txheej txheem reorganization ntawm cov kua molecules vim ntws.
Yuav ua li cas koj thiaj paub tias shear thinning?
Shear thinning Performance index tuaj yeem xam los ntawm faib pom meej viscosity ntawm qhov qis tshaj plaws los ntawm tus nqi ntawm qhov pom tseeb viscosity ntawm qhov ceev tshaj plaws(feem ntau ntawm 2 thiab 20 lossis 5 thiab 50 rpm). Qhov txiaj ntsig piv tau yog qhov ntsuas ntawm shear thinning.
Vim li cas xim shear thinning?
Cov xim yog cov khoom sib cais uas feem ntau pom cov cwj pwm ua kom nyias nyias. Shear thinning tshwm sim vim qhov kev taw qhia shear-induced thiab disaggregation ntawm cov khoom nyob rau hauv cov kev taw qhia ntws.
