Heat Setting

Basically all needle felts at Shandong Aobo are heat-set.
The residual shrinkage is reduced to a minimum by means of an optimum combination of the decisive quality factors , such as temperature, dwell time and cooling phase.

The controlled process management during the cooling phase ensures that the filter bags will have excellent form stability even under most difficult conditions.

Quality-determining parameters

  • Temperature
  • Reaction time
  • Cooling time

Thermal surface treatment

The surface of any needle felt influences the structure of the filter cake, its cleanability as well as pressure drop and the emission.

- Singed

Three different kinds of treatment are possible:

  • smooth for adhesive and moist dust
  • medium for universal treatments
  • rough low agglomeration or fine dust

- Calendering

Through calendering a more compact fiber structure is achieved. This allows a more surface-active separation of dust with lower emission.


Protective Impregnation

- hydrophobic, oleophobic

This treatment makes it more difficult for moisture to penetrate into the needle felt. Thus the risk of excessive dust deposits and caking is reduced.

- Protection against acids and hydrolysis

Special impregnation based on TEFLON®. This treatment coats the fiber surface, thus providing it with the anti-adhesive character of a PTFE finish.

An oil- and water-repelling effect is produced, and the fibers are effectively protected against acid and hydrolysis attack.

- Active finish, hydrophobic

Special water-repellent treatment providing a high cleaning and separation efficiency.


Coatings

Through the filter-active coating dust is already separated on the surface. In addition the anti-adhesive surface reduces the adhesive forces between the filter medium and dust cake.


Advantages

  • Optimised cleaning
  • Increased service life
  • High separation efficiency
  • PTFE-Coating, hydrophobic and oleophobic fibers, protection against acids and hydrolysis
  • Primary finish membrane, microporous foam coating, high separation efficiency, easy dust release, hydrophobic and oleophobic
