Production Technology of PTFE Membrane Filter Bags

PTFE micro-pore membrane material short for Micro-pore Membrane Poly tetra fluoroethylene material takes Poly tetra fluoroethylene(PTFE)  as its raw materials.PTFE is puffing into one multipore membrane,then coated on bases of varied textile or paper to get new filter material. PTFE has features of smooth surface,chemical-resistance. When it is coated one ordinary filter material surface,it realizes functions of one-time dust layer: surface filter is achieved by blocking all dust on its membrane surface. Thus it has incomparable advantages over traditional filter materials.

In addition, due to its high peel strength,high air permeability,low resistance,concentrated ,uniform and well-distributed pores,PTFE membrane materials frequently used as filter bags or pleated-like filter cartridges from bag filters,blocking effectively and rapidly fine dust powder at high efficiency. It is also one kind new economical and effective filter material in terms of industry dust filter and material recovery.

Following are advantages in use of PTFE filter bags:

PTFE membrane filter bags meets local new environment control standards and growing demands of people upon environment; secondly well control of dioxin to keep its density below 1ng-TEQ/N,even below 0.1ng-TEQ/N among  Yangtze River Delta region,the developed areas. Lastly it assures safe and reliable operation of related systems.

According to a survey,service condition of filter bags is facing serious challenges among current over 50 garbage power plants:frequent filter bags damage,low resistance,oxidation etc. Though varied cases for above phenomenons,PTFE membrane filter bags may help to reduce bags replacement frequency and consumption cost due to its reliable and safe performance.
