Bricks show no loss of useful mechanical properties even when 20-30% of their content is slag. Nor do they leak.
即便当渣含量达20% - 30%时,制成砖并未显示出有用力学性能的损失,同样也没有产生裂纹。

The effect of grafting on the crystallization and dynamic mechanical properties of PP have also been investigated by the determination of the crystallization rate and dynamic mechanicalloss.
通过测定结晶速率和动态力学损耗的方法研究了接枝对聚丙烯的结晶行为和动态力学性质的影响。
