China Good Quality Basalt Fiber Roving 180tex 1200tex 2400tex 4800tex
Product Description
Basalt fiber, made from basalt rock, is able to withstand temperatures up to 1800F/982C. Basalt fiber products are made of 100% continuous-filament, manufactured in thicknesses to suit a broad range of applications including:
• Versatile way to protect structural steel from fire and heat devastation
• Engine exhaust systems
• Hot section heat shields
• Industrial and domestic furnaces
• Turbines
• A safe asbestos replacement
• High sound absorption for noise abatement
• Fire protection/containment in refineries and oil rigs
• Refrigeration insulation Basalt mat/felt provides very low thermal conductivity and can withstand continuous working temperatures in excess of 1500F/816C, making it a flexible material that ensures exceptional high-temperature performance
With excellent drapeability, basalt fiber products conform to irregular surfaces to meet a variety of design needs, while its chemical properties make it highly durable and safe.
• Non-respirable, 13 micron filament diameter
• Meets chemical acceptability of NRC Guide 1.36, section C
• Very high alkali and acid resistance (surpassing most mineral and synthetic fibers)
• Negligible moisture absorption (less than 1% at 65% relative air humidity)environmental
• Remarkable immunity to nuclear radiation, UV light and biologic contamination
Using a natural volcanic basalt rock as raw material, basalt roving is produced by melting the rock in a furnace at 1450-1500 degrees C. The molten material is then forced through platinum/rhodium crucible bushings to create fibers (roving). This technology, named continuous spinning, results in continuous fibers.
From there the basalt roving continuous fibers can be made into many different products
Basalt Chopped Fiber for reinforcement in various applications
Basalt Fabrics for the textile industry
Basalt Rebar and Basalt Mesh for the construction industry.
Features of basalt yarn:
Consistent Linear density
Good sizing protection and low fuzz
High tensile strength
Good thermo-stability
