Is the polyester needle punched felt dust removal bag corrosion-resistant

In industrial production, the emission of various acidic and alkaline corrosive gases and liquids is a common phenomenon, which puts forward high requirements for the corrosion resistance performance of dust removal bags. As a widely used dust removal material, the corrosion resistance of polyester needle punched felt dust removal bags has attracted much attention. This article will delve into the corrosion resistance of polyester needle punched felt dust removal bags, helping customers better understand their application scope and limitations.
1、 Material characteristics of polyester needle punched felt dust removal bag
Polyester needle punched felt dust removal bag is a felt like filter material made mainly of polyester fiber and processed through needle punching technology. This dust removal bag has a relatively tight fiber structure and high strength, and can withstand certain pressure and friction. However, the acid and alkali corrosion resistance of polyester fibers themselves is relatively weak. Therefore, specific analysis is needed for the corrosion resistance of polyester needle punched felt dust removal bags.
2、 Corrosion resistance of polyester needle punched felt dust removal bag
Acid alkali corrosion: The polyester needle punched felt dust removal bag has a certain tolerance in acidic and alkaline environments. However, the different acidity and alkalinity have different effects on its corrosion resistance. In acidic environments, the corrosion resistance of polyester needle punched felt dust removal bags is relatively good, while in alkaline environments, their corrosion resistance is relatively weak.
Oxidizing agent corrosion: The polyester needle punched felt dust removal bag has certain stability against certain oxidizing agents and is not prone to oxidation reactions. However, certain strong oxidants may cause damage to polyester fibers, affecting their structure and properties.
Solvent corrosion: Some organic solvents may cause certain swelling effects on polyester needle punched felt dust removal bags, affecting their filtration performance and service life. Especially in high temperature and concentrated solvent environments, the corrosion resistance of polyester needle punched felt dust removal bags may be greatly affected.
