The application of polypropylene membrane in MBR could resolve the problems of short life span and low strength that arc usually possessed by other material of membrane.
Considering the membrane effect of plates, the design of profiled steel sheets allows local buckling of plates, and can utilize post - buckling strength.
由于板件的薄膜效应,压型钢板的设计不仅答应板件出现局部屈曲,而且还可以利用屈曲后强度。

The reinforced microfiltration membrane was prepared by changing the kind and content of plasticiser and, then the appearance, strength and flow of the membrane were lion investigated.
