Cov kev ntsuas rheological yog viscosity (cp), torque%, shear stress (dyne/cm2) thiab shear rate (s- 1).
Dab tsi yog qhov txawv ntawm rheology thiab viscosity?
Qhov sib txawv tseem ceeb ntawm rheology thiab viscosity yog qhov rheology yog kev kawm txog qhov ntws ntawm cov teeb meem, whereas viscosity yog ib qho kev ntsuas ntawm nws qhov tsis kam mus deformation. Rheology yog ib ceg ntawm physics los yog lub cev chemistry, thaum viscosity yog ib qho kev ntsuas ntau uas muaj txiaj ntsig zoo hauv chemistry.
Dab tsi yog cov khoom rheological?
Rheology cov khoom yog kev tshwm sim ntawm tus nqi thiab qhov xwm txheej ntawm deformation uas tshwm sim thaum cov khoom raug ntxhov siabCov kev txwv no tuaj yeem siv los kwv yees seb cov kua dej yuav coj li cas hauv cov txheej txheem thiab txiav txim siab lub zog xav tau rau kev thauj cov kua los ntawm ib qho mus rau lwm qhov hauv kev cog qoob loo.
Kev sib raug zoo ntawm rheology thiab viscosity yog dab tsi?
6.1 Taw qhia. Rheology txhais tau tias yog kev kawm txog kev deformation thiab ntws ntawm cov kua dej. Nws yog ib qho tseem ceeb ntawm cov khoom siv molten polymer; Nws hais txog qhov viscosity nrog qhov kub thiab txias, thiab yog li txuas rau polymer txheej txheem.
piv txwv ntawm cov khoom rheological yog dab tsi?
Piv txwv ntawm cov khoom muaj xws li elasticity, poisson ratio thiab so lub sij hawm so thiab shear modulus.
Muaj peb hom moduli yuav raug xam rau Hookan cov khib nyiab nyob ntawm txoj kev siv lub zog:
- Modulus ntawm elasticity (E)
- Modulus ntawm rigidity (G)
- Modulus of bulkiness (K)
