Properties and applications of polyester three-anti-needle felt

Polyester three-anti-needle felt, refers to the waterproof, oil-proof and anti-static polyester filter bag. In the production places of metallurgy, chemical industry, etc., there is large dust and contains moisture static characteristics, if you use ordinary polyester filter bags, during the dust removal process,the dust will pass through the surface of the filter bag, and adhere to the bag surface or even block the micropores of the filter bag, greatly reducing the work efficiency and the service life of the dust filter bag. After the filter material surface is treated with PTFE coating, the wear resistance, folding resistance, corrosion resistance of the filter cloth will be well improved.

The polyester three-anti-needle filter bag is characterized in that the fiber fineness is less than 10 micrometers, and the single fibers are randomly distributed to each other.

Friction charge density/(μC/㎡): <7

Friction potential/V: <500

Half-value period/s: <1

Surface resistance/Ω: <10¹⁰

Volume resistance/Ω: <10⁹

When the dust from the feed inlet enters the filter bag through the the dust collection pipe, the surface layer of the dust in the filter bag is empty and discharged to the outside of the filter bag, and the dust stays in the dust filter bag. The dust in the bag is cleaned to ensure no pollution.
