Polyester normal temperature needle felt is a fine fiber cloth in which fibers are staggered and the gaps are evenly distributed by non-woven needle punching process. The surfaces of needle felts produced from polyester staple fibers and polyester twisted yarns are hot-rolled, singed or coated. After the post-treatment, the surface of the filter is smooth and smooth, and it is not easily blocked by dust. The filter has a large voidage, good air permeability, a wide range of uses, strong chemical stability, and can not only filter the normal temperature gas but also filter the acid and alkali. The corrosive gas, and can filter water, oil, is the normal temperature conditions, liquid-solid separation and other fields ideal filter material.
Advantages
Polyester acupuncture filter felt has the characteristics of high porosity, good air permeability, moderate acid and alkalinity, and excellent abrasion resistance. It is the largest used in felt filter media. A variety of species.
Performance
- Polyester needled felt is made of fine and short fibers with staggered arrangement and uniform pore distribution. The porosity is up to 70%, which is twice that of woven filter fabric.
- High dust removal efficiency and low gas emission concentration.
- Polyester needle felt surface after hot rolling and singeing or coating finishing, smooth, not easy to plug, no deformation, easy cleaning, long service life.
- Anti-static needle felt has anti-corrosion blast furnace gas and cement mill dust bag electrostatic discharge electrostatic discharge, the function of deriving static electricity.
Field of Application
Polyester acupuncture filter felts are used in many industries such as metallurgy, chemical engineering, building materials, machinery, petroleum, pharmaceuticals, food processing, etc., in process applications, material recovery, air purification, dust control, and liquid filtration.
