Blister ntim tshuab blister PVC non-Newtonian pseudo kua

Lub polyvinyl chloride yaj yog ib qho uas tsis yog-Newtonian pseudo-kua kua. Qhov loj dua tus nqi shear, qhov me dua qhov pom tseeb viscosity, thiab qhov kev hloov pauv yog qhov rhiab heev. Thaum qhov kub nce, qhov viscosity tsis txo qis ntau. Txawm hais tias cov yas qis dua qhov kub ntawm qhov decomposition, nws yuav ua rau kub thiab oxidative degradation vim qhov kub thiab txias rau lub sijhawm ntev, uas yuav cuam tshuam rau nws cov kev ua tau zoo. Yog li ntawd, txhawm rau txhim kho qhov fluidity ntawm polyvinyl chloride yaj, lub ntsiab kev txiav txim siab yuav tsum tau nce tus nqi shear (nce lub siab). Qhov tseeb, ua kom lub zog sab nraud pab txhawb kev txav ntawm macromolecules, uas txo Tf thiab ua kom cov macromolecules ntws ntawm qhov kub thiab txias.
