product name: water-and-oil-repellent-needle filter felt

During the running of dedusting bags, the gas includes
moist, hygroscopic and deliquescent powders. It will create
the water or oil membrane on the surface of powder to
increase the cohesion, but it will make the dust removal
more difficult. Especially under the high temperature, it
will directly affect the normal work by dewfall due to the
outer cool air. Considering this, ordinary felt has to
adapt the special treatment to improve the working
efficiency. In recent years, our company treats the
polyester felt, polypropylene felt, anti-static felt, and
Aramid felt with the active fluoride.
