Performance parameter table of P84 needle filter felt

Details of the introduction

The P84 needle punched felt produced by our company is made of polyimide fiber P84 produced by Austria Lenzing Inspec Fiber company, similar products and French Kernel Kernel fiber. P84 fiber filter material has no melting point temperature, and it is naturally golden yellow. Fiber filter P84 polyimide fiber filter is not hygroscopic (at 65% relative humidity conditions, water quantity is about 3%).
The material has excellent high temperature resistance, chemical corrosion resistance and wear resistance. It is a kind of high temperature resistant synthetic fiber, which is not resistant to hydrolysis. It has a trifoliate cross section. With the increase of the surface area of the single fiber, the effectively trapped particles are non thermoplastic fibers, and the glass fiber has a stronger wear ability than the pulsing ash. Glass fiber can be replaced under the condition of wear resistance.
P84 dusting bag has always been a member of high price dusting bag in high temperature dust collection bag, but the use of P84 dust bag will get good dust removal effect. It is often used under the harsh conditions of high temperature corrosion.
Processing postprocessing: high temperature setting, singeing and calendering, water and oil repellent, anti-static, PTFE coating, emulsion, surface coating
The characteristics of the filter product: flame retardant, high temperature resistance, corrosion resistance, non hydrolysis, good wear resistance, long service life and so on.

 

Attention point

1. before entering the filter bag, the best desulphurization treatment is carried out.
The content of 2. nitrogen and oxygen compounds NOx < 600mg/Nm3;
3. the content of sulphur oxide SOx < 600mg/Nm3;
4. oxygen content O2 < 22%, water content H2O < 35%.
Bag style: external interface, one round flange
Bag: hot melt, seam
Bag tail: the bottom of the circle, the bottom of the ellipse, the bottom of the new bag
* style sizes can be customized in accordance with needs

 

Application areas:

P84 is mainly used for flue gas purification such as asphalt mixing, cement kiln, drying, combustion, smelting, various industrial kilns, coal-fired boilers and garbage incineration, and is widely used in high emission concentration process.
