Vibration force field was introduced into processing of plastics in tri-screw dynamic mixing extruders,so as to intensifying mixability and dispersion.
Methods of enhancing dispersing mixability in dynamic molding process,the structure of the dynamic mixing extruder and its operation principles were introduced.
The dynamic rheological behavior and non-isothermal cold crystallization of poly(ethylene terephthalate)(PET)were studied to reflect the disentanglement effect of the pulsatile extrusion flow field.
通过分析 PET 熔体的动态流变参数和结晶动力学过程的变化,间接证实动态挤出聚合物熔体分子的解缠结作用。
Unique straight or spiral grooved feed bush with force cooling system and unique screw ensure high plastification in low temperature, high speed extrusion of material.
Here PMN's that are marginated along the venule wall (arrow) are squeezing through the basement membrane (the process of diapedesis) and spilling out into extravascular space.
