What excellent performance characteristics does basalt needle punched filter felt have to meet the needs of diverse applications?

1. Excellent high temperature resistance:
Basalt fiber itself has the characteristics of high temperature resistance, and the use temperature of basalt needle punched filter felt can reach 300℃. This enables basalt needle punched filter felt to maintain good filtration performance in high temperature environment and is suitable for various high temperature gas filtration occasions.
2. Good mechanical properties:
The tensile test results of the product show that the tensile force of Warp/Radial and Weft/Zonal is not less than 1800 (N/5 x 20cm). This shows that basalt needle punched filter felt has high tensile strength and can withstand certain mechanical loads to ensure stability and durability during the filtration process.
3. Acid and alkali corrosion resistance:
Basalt fiber has acid and alkali resistance, so basalt needle punched filter felt also inherits this advantage. In acid and alkali environments, it can still maintain good filtration efficiency and physical properties, and is suitable for the filtration of various corrosive gases.
4. High filtration efficiency:
The filtration efficiency of basalt needle-punched filter felt is as high as 99.9%, which means that it can effectively intercept tiny particles in the air and ensure the quality of the filtered gas. This is especially important for occasions that require high-precision filtration, such as electronics, pharmaceuticals, food and other industries.
5. Stable structure and moderate thickness:
The weight per unit area of ​​basalt needle-punched filter felt is 900/950g/m², and the thickness is between 2.4~3.0 mm. This design of stable structure and moderate thickness makes the product have good air permeability and filtration effect, while ensuring that it is not easy to deform or break during use.
6. Wide range of applications:
Basalt needle-punched filter felt is also widely used in fire retardant, composite reinforced substrate, high temperature resistance, ablation resistance and other fields due to its high temperature resistance and acid and alkali corrosion resistance. This further proves its superiority and practicality as a high-performance filter material.
