HL-XWY basalt fiber chopped strand is a new type of inorganic environmentally friendly green high-performance fiber material. It is a basalt ore composed of oxides such as silica, alumina, calcium oxide, magnesium oxide, iron oxide and titanium dioxide at 1500℃. It is made by drawing after high temperature melting, and uses basalt ore as raw material. Basalt fiber chopped strands not only have high strength, but also have excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. When mixed into cement concrete and asphalt mixtures, they have strong crack resistance and crack resistance, and enhance toughness. .

Product specifications

Chemical composition of basalt fiber chopped strands

Technical index of basalt fiber chopped strand

Characteristics of basalt fiber chopped strands:

1. High temperature resistance, low temperature resistance (-269~650℃)

When mixed with asphalt at high temperature, the performance of the material will not be thermally degraded, nor will it undergo chemical or dissolution reaction with asphalt, effectively changing the low-temperature hardening and high-temperature softening of asphalt.

2. Excellent waterproof and erosion performance, low water absorption rate, moisture absorption rate less than 0.1%, and its absorption capacity does not change with time.

3. Elastic modulus (93~110GPa)

4. High tensile strength (2800~3800MPa), the tensile strength is 2~2.5 times that of metal, and the tensile strength remains stable at 100~250℃.

5. High sound absorption coefficient (0.9~0.99), low thermal conductivity (0.03~0.038w/m.K)

6. Stable chemical properties, wear resistance, chemical corrosion resistance, and excellent anti-aging.

7. It has good surface affinity with cement concrete and asphalt or concrete. Basalt fiber chopped strands are directly drawn from natural volcanic rock. When mixed with cement and concrete, they have good dispersibility, strong binding force, and consistent thermal expansion and contraction coefficients. .

Application scope:

Basalt fiber chopped strands are stable in volume after being mixed with cement concrete and mortar, and have good workability and durability. They have excellent reinforcement and toughness, anti-seepage and crack resistance, impact resistance, and extend the service life of buildings. It can be widely used Used in the field of national defense and transportation engineering infrastructure, petrochemicals, fire protection, environmental protection, automobiles, shipbuilding and other fields. It can be used in houses, bridges, highways, high-speed railways, urban elevated roads, airstrips, seaports, subway tunnels, etc. Construction sector.
