英语翻译
A large amount of theoretical and experimental research has been
conducted on extrusion processes involving gas-liquid mass transfer.
The emphasis has been put on the extruder die end and beyond where gas
bubble nucleation and growth occur.Little or no attention has been paid
to studying the gas dissolution process that takes place in the extruder
after gas is injected in the melt.Abetter understanding of the main mechanisms
for gas dissolution will provide guidance to proper process
control,design and optimization.This is especially important when inert
gases,which generally have very low solubility in polymers,are used as
blowing agents,since the use of these gases requires much higher extrusion
and die pressure,which,in turn,do not favor foaming efficiency.
