Filtration cannot be ignored. The type and usage of filter aids and Baishi should be adjusted according to different passes, different products, and different machines to make the filtration work periodic and regular.

General principles:
a) The cold rolling mill uses coarser filter aids to ensure flow, and the foil rolling mill uses finer filter aids to ensure filtration accuracy:
6) In the two passes after cold rolling and the two passes before foil rolling, due to the large amount of aluminum powder produced and the slightly larger amount of clay used, the filtration cycle should be shortened appropriately. C) A monitoring filter must be used, and the filter core is generally used 3m ~5m is enough. Under normal production conditions, replace it every three months.
