利用扫描电子显微镜研究了PVC用抗冲击改性剂的喷雾干燥粒子实际形态，提出了提高表观密度的基本思路。
The real morphology of the modifiers were studied by SEM. The methods and ideas for improving the apparent density of modifiers for the PVC were put forward.
此外，颗粒整形后的再生骨料的表观密度、水率也略有所提高。
In addition? The recycled fine aggregate after particle shaping its apparent density and water absorption have been improved slightly.
而较低的温度下，表观密度随螺杆转速的提高而增大。
While at lower temperature, apparent density increases with the increasing of screw revolution speed.
