Title:
METHOD TO FORM A DUST COLLECTING LAYER ON A POROUS BODY WITHOUT USING A BINDER
Document Type and Number:
WIPO Patent Application WO/2024/048781
Kind Code:
A1
Abstract:
To provide a manufacturing method of a filter element in which fine particles constituting a dust-collecting layer are not peeled off and high performance is maintained over a long period of time even when the filter element is scaled up. A layer of fine particles containing low melting point fine particles and small diameter fine particles is deposited and formed on the surface of a filter element material while sucking the filter element material, and the layer of the fine particles is heated by a heating means exemplified by an infrared heater and an oven to sinter the fine particles to form a dust-collecting layer.
