Description

Nonwovening filter cloth Needle punched felt are mainly used for liquid filtration , air filtration and dust collection , compared with ordinary filter 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 , difficult to stop up and out of shape , easily -dedusting and long using -life usually 1 to 5 times longer than mechanical filter cloth , ***** use and good chemical stability , it can filter normal atmospheric temperature 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 , ***** is an idear medium to separate liquid from solid and ideal material to purify and filter gas .
