提高金属纤维毡过滤精度的方法研究

A Method for Increasing the Fiber Felt Accuracy

研究采用纤维增粗法来提高纤维毡精度。用不锈钢纤维毡作为基体,分别采用电镀、化学镀和原位水热法提高纤维的丝径,以提高过滤精度。利用扫描电镜观察了处理后的形貌,并测试了透气量和泡点压力,结果表明,3种方法均可以有效提高纤维毡的过滤精度。

Propose methods of fiber enlargement for increasing the fiber felt accuracy. The electroplating, electroless plating, and situ hydrothermal methods are respectively used to improve the wire diameter in order to improve the filtering precision of the fiber. These prepared membranes are characterized by means of SEM, permeation volume and filtration accuracy is also tested. The results show that the three methods can effectively improve the filtering accuracy of fiber felt.
