Description

Fiberglass needle-punched filter felt is a filter material with reasonable structure and good performance. Fiberglass has outstanding dimensional stability, high tensile strength at break , corrosion resistance, smooth surface, good water-repellent, breathable, easy cleaning, chemical stability. Fiberglass is used as raw material, and the carded chopped fiberglass is needle-punched. The fibers between the fiberglass and between the fiberglass and the base cloth are entangled with each other by mechanical methods to make a non-woven filter material.

Advantages of Fiberglass Needle-Punched Filter Felt

  • Temperature resistance: Glass fiber has high temperature resistance, so it can maintain stable performance in high temperature environment and is suitable for high temperature working conditions.
  • Chemically inert: It is inert to many chemical substances and not susceptible to corrosion, so it is suitable for handling various chemical liquids and gases.
  • Mechanical strength: Needle-punching process can form a strong mechanical connection between the fiber layers of the glass fiber felt, which improves the mechanical strength and durability of the filter felt.
  • Microfiltration: The diameter of the glass fiber is finer, which can produce a filter mat with a denser fiber structure, thereby achieving a more efficient microfiltration effect.
  • Adsorption performance: Due to the microstructure of the fiber surface, it has a certain adsorption capacity and can be used in some occasions that need to remove suspended particles and particles.
