Cleaning filter components |
摘要 |
A method of cleaning a filter component comprises subjecting the component to an atmosphere of superheated steam at a pressure of a least 0.5 bar in a vessel and subsequently decompressing the vessel to achieve a pressure reduction of at least 0.5 bar in at most 5 seconds. The method is particularly useful for the cleaning of filter components that have been used for the filtration of molten polymer (e.g. polyester) and which are at least partially blocked by solidified polymer.
