| There are various types of products of polymer latex, they play an important role in national economy. Polymer latex with core-shell structure has various function because of the difference between components of core and shell of particles.This paper researches viscosity of polymer emulsion with core -shell structure based on the theory of viscous fluid mechanics, deduces the relation between viscosity and other parameter which effect the viscosity, gives simulation curves, and then compares the outcome with experiment.This article also discusses sound-absorbing property of polymer material with spherical hollow structure by effective parameter method according to the characteristic of sound-wave in reflecting or refraction. It will obtain the relationship between sound-absorbing coefficient and the effective parameters, and draw the relationship figures with MatLab.The results indicate viscosity coefficient of polymer emulsion... |
