Product Description

 Shanghai BG group have selected inspec fibers polyamide fibers from Austria lenzing company, guided by the foreign professional company and then we produced the p*4 high temperature resistant needle punched filter felt-one new type of high temperature resistance. We are the first enterprise for its volume production at home. It has three remarkable features:

1. Remarkable high temperature resistance:

2. Favorable chemical resistance: It has been proved that p*4 filter bag has the excellent filter value for the acid waste gas, alkali powder and dust in the past waste incineration more than *0 years.

3. The efficiency of low back wash pressure and high elasticity mud cake release. The feature of p*4 fiber is much remarkable because of the fine fiber and the fiber surface area increases to the max even due to the irregular fiber cross section, which supplies more microspores resulting in the better filter efficiency than the depth filtration. The dusts only rest on the filter felt surface not penetrating in it, so the efficiency of low back wash pressure and mud cake release could be improved, which has excellent superfine particle collecting efficiency and small operating pressure difference. There is much experience for using p*4 filter material in the gypsum plant, cement plant, waste incinerator, liquid bed boiler, coal-fired boiler etc.
