MANUFACTURING METHOD OF FILTER MEDIA AVAILABLE AT MEDIUM AND HIGH TEMPERATURE EASILY CONTROLLING PORE SIZE

摘要

The present invention relates to a manufacturing method of filter media for treating medium and high temperature exhaust gas through optimization of an operating condition for foam formation by using a fluoride resin. The manufacturing method of the present invention is able to easily manufacture foams having a foam size distribution property specialized in a range of 10-40μm on average according to the operating condition for foam formation, contrary to the conventional inventions to minimize the foam size. Pores having various sizes are formed on the surface of filter media through foam coating, which can be applied to various applied fields in a medium and high temperature region.
