Basalt fiber is a kind of glass fiber. It is a continuous fiber made of platinum-rhodium alloy wire-drawing leak plate at high speed. Basalt fiber is a new kind of inorganic environmental friendly green high-performance fiber material. It is made of oxides such as silica, alumina, calcium oxide, iron oxide and titanium dioxide. After melting at high temperature, the basalt material is rapidly drawn through a leaky plate. Basalt continuous fibers not only have good stability, but also have many excellent properties such as electrical insulation, corrosion resistance, combustion resistance and high temperature resistance.
Material | Basalt | Type | chopped |
Diameter | 8-31μm | Density | 2.7g/cm³ |
Melting Point | 1600℃ | Heat resistance | 650℃ max |
Acid &Alkali Resistance | Strong | Water absorbency : | No |
Tensile Strength | 1250Mpa MIN | Elastic Modulus | 45Gpa Min |
Crack Elongation: | <3.8% | Length | 3mm-60mm |
1. High temperature resistance, low temperature resistance (-269-650 C)
When mixing with asphalt at high temperature, the material performance will not be thermal degradation, nor will it react with asphalt chemically or dissolve, effectively changing the low temperature hardening and high temperature softening of asphalt.
2. Waterproof erosion performance is superior, water absorption rate is low, moisture absorption rate is less than 0.1%, and its absorption capacity does not change with time.
3. Modulus of Elasticity (93-110 GPa)
4. High tensile strength (2800-3800 MPa), 2-2.5 times the tensile strength of metal, and stable tensile strength at 100-250 (?)
6. Chemical stability, wear resistance, chemical corrosion resistance, excellent aging resistance.
7. Cement concrete and asphalt or concrete have good surface affinity. Basalt fiber is made of natural volcanic rock directly. When mixed with cement and concrete, it has good dispersion, strong binding force, and the coefficient of thermal expansion and cold contraction is the same.
Basalt fibers mixed with cement concrete and mortar have stable volume, good workability, good durability, excellent reinforcing and toughening, anti-seepage and anti-cracking, anti-impact and prolonging the service life of buildings. They can be widely used in the field of national defense and transportation engineering infrastructure, petrochemical industry, fire protection, environmental protection, automobile, ship manufacturing and other fields, and can be used in buildings and bridges. Expressways, high-speed railways, urban viaducts, airstrips, harbour terminals, metro tunnels and other construction areas.
