Study of the Bubble Break-up in Polymer Melt Flow Field
In recent years much research work has been reported about the deformation of a dispersed single droplet under the simple shearing flow field or Newton flow field. This investigation has a great significance upon the dispersion or mixing of the multiphase polymer blends. Similar to this, the dynamics of bubble shape and breakup of bubble under polymer melts field is also well worth studying since its importance upon the dispersion and mixing of the multiphase polymer blends. To obtain the rules of breakup of bubble when the gas is into the polymer melt flow field, a series of experiments were carry out observations the CO2 gas and the polymer melts in elongation flow field, through changing the experiments condition such as temperature, gas injection pressures and so on. It was found that the state of bubble breakup for the different experiment conditions was changed greatly. Therefore several different bubble break-up processes were characterized.
