Basalt filter cloth is an excellent material for filtration applications, known for its high temperature resistance, durability and chemical stability. The fine weave of basalt fiber provides effective filtration, trapping small particles while allowing air or liquid to pass through. It is often used in industrial environments where traditional materials do not perform well. It not only has perfect high temperature resistance, but also can be completely degraded, and is an environmentally friendly industrial material. Filmedia® focuses on filtration solutions, we are a professional manufacturer of various filtration products.

Description

Basalt Fiber Cloth with Excellent Functional Properties

  • High strength: Basalt fiber cloth has high strength and can meet the needs of a variety of structural materials.
  • High temperature resistance: Basalt fiber cloth has excellent high temperature resistance, short-term temperature resistance can reach more than 1000℃, and can be used for a long time in a temperature environment of 760℃. It is an ideal material to replace asbestos and glass fiber cloth.
  • Flame retardant: Basalt fiber cloth has permanent flame retardancy, is not easy to burn, and does not produce harmful gases during combustion.
  • Insulation: Basalt fiber cloth has good electrical insulation properties and is suitable for electrical insulation.
  • Weather resistance: Basalt fiber cloth can maintain stable performance even in a strong ultraviolet environment.

Types of Basalt Filter Cloth

Compared with glass fiber, basalt fiber fabric is a material with higher tensile strength. Although its weaving property is slightly worse than that of carbon fiber, it is still a good alternative due to its low price and environmental protection. The structure of basalt filter cloth fiber fabric mainly depends on its weaving method. Common weaving structures include:

Plain weave
It is interwoven with one warp yarn and one weft yarn. The fibers cross more and constrain each other, making the fabric stronger and more wear-resistant.
Twill weave
It is woven by one warp yarn through two weft yarns, which has a three-dimensional sense and is often used for decorative products.
Satin weave
One warp yarn passes through three or more weft yarns, with a higher density, but the strength is slightly lower than plain weave and twill.

Applications

  • Dust Filtration: Basalt filter cloth is commonly used in dust collection systems, particularly in industries like cement, steel, and power generation, where fine particulate matter needs to be captured efficiently.
  • Air and Gas Filtration: Suitable for air filtration systems, especially in high-temperature environments.
  • Liquid Filtration: Used in certain liquid filtration processes, especially where high resistance to chemicals and temperature is required.
  • Industrial Exhaust Systems: Ideal for filtering flue gases and exhaust from industrial processes.
