旋转圆筒型过滤膜在精密平衡过滤难分离物质时，由于高速旋转的过滤膜对附着在过滤膜表面的滤饼层产生很大的扫流力，过滤时不断扫流过滤膜表面生成的滤饼，使过滤能够保持连续稳定的过滤速度。本研究通过难过滤性物质ＰＭＭＡ液浆和Ｏ／Ｗ乳浊液的高速连续稳定的精密平衡过滤，对旋转精密平衡过滤的特性和操作参数进行了有益的探讨。 Rotating cylindrical filter membrane in the precise balance of filtration difficult to separate substances, due to the high-speed rotation of the filter membrane attached to the surface of the filter cake filter layer has a great sweeping force, the filter constantly swept the surface of the filter membrane filter Cake, so that filtration can maintain a continuous and stable filtration rate. In this study, through the high-speed continuous and stable precision balance filtration of the non-filterable PMMA liquid and O / W emulsion, the characteristics and operational parameters of the rotating precision balance filtration were discussed.
