Description

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.
