The performance of dust removal filter bags is closely tied to their materials, which vary in temperature resistance, chemical resistance, and abrasion resistance. Key materials include:
- Polyester fiber filter bags: Offer good acid and alkali resistance and abrasion resistance, suitable for general industrial applications like machining and construction materials, with low cost and easy maintenance.
- Polypropylene fiber filter bags: Excel in corrosion resistance, ideal for harsh chemical environments in industries such as chemicals and pharmaceuticals.
- Glass fiber filter bags: Feature exceptional high-temperature resistance (up to 200°C+), widely used in steel, power generation, and waste incineration for treating high-temperature flue gas.
- Metamax (aramid) filter bags: Provide both high-temperature resistance (continuous use at 204°C) and flexibility, suitable for demanding scenarios like asphalt mixing and smelting, with significantly longer service life than standard materials.
Beyond materials, filter bags can be tailored for different filtration precision levels, from micrometers to nanometers, ensuring effective capture of particles of varying sizes. In industry, they are widely applied in steel, cement, chemicals, power generation, and environmental sectors like waste incineration and wastewater treatment, enabling green production by reducing dust emissions.
For example, high-temperature glass fiber bags handle cement kiln flue gas, while polypropylene bags withstand corrosive gases in chemical plants. Choosing the right material and specifications not only enhances dust removal efficiency but also extends equipment lifespan and reduces maintenance costs, making it a critical step in optimizing industrial dust control systems.
