The results show that by lowering the fusant temperature and raising the cross airblasting speed properly, we can keep the degree of profile at a reasonable scope.
结果表明，适当降低熔体温度和提高侧吹风速度，可以提高丝条异形度的保持率。

Combining the chemical cleaning and airblasting method, this paper introduces a new method of removing the deposit resulting from the shift gas and catalyst powder, etc.
The results show that the apparent density of hard elastic polypropylene increases with a lower melt temperature, or a higher draft ratio, or a higher airblasting speed.
