Needle punched felt are mainly used for liquid filtration,
air filtration and dust collection. Compared with ordinary
fi lter material,needle-punched felt has many advantages as
following:1.High hole rate and good air permeability can
increase the loading ability of the equipment and reduce loss
and energy consumption. 2.High efficiency of cleaning and
low density of gas. Gas density can be greatly lower than the
country standard stipulation.3.After Heating, singeing and
coating treatment, the surface should be smooth, diffi cult
to stop up and out of shape, easily-dedusting and long
using-life usually 1 to 5 times longer than mechanical fi lter
cloth. 4.Exten-sive use and good chemical stability. It can
fi lter normal atmospheric tem-perature or high-temperature
gas including corroding gas mixed with acid and alkali,
water, oil. Needle-punching felt is widely used in metallurgy,
chemical industry, building Materials, smelting, generating
electricity, pottery, machinery, mine, petroleum, dyestuffs,
food, grain processing, etc. It is an ideal medium to separate
liquid from solid and ideal material to purify and fi lter gas.
