  • Basalt fiber geogrid:

    Basalt fiber yarns that are alkali-resistant, acid-resistant, and corrosion-resistant are selected as raw materials, and are woven into base materials by foreign advanced warp knitting machines. Make full use of the strength of the yarn in the fabric to make it have good tensile strength, tear resistance and creep resistance, and it is a plane network reinforced geotechnical material that is coated with modified asphalt or PVC latex.

    Characteristics of basalt fiber geogrid:

    Basalt fiber has the advantages of high temperature resistance, freeze-thaw resistance (-260~650°C), consistent thermal expansion coefficient with asphalt concrete, high tensile strength, UV protection, good chemical stability, and anti-aging, so it can be used for road reinforcement. Resist cracks, ruts and other road diseases, and end the problem that asphalt pavement is difficult to strengthen.

    The ratio of the elastic modulus of basalt fiber asphalt concrete to the elastic modulus of asphalt concrete at room temperature is as high as 24:1. It has a high resistance to deformation, and the elongation at break is about 3.1%. Since the mixing temperature of asphalt mixture is as high as 190°C, high temperature-resistant basalt fiber is a new material that can replace polyester fiber and lignin fiber. It not only meets the high temperature resistance requirements of asphalt mixing construction up to 190 ℃, but also is an excellent building material for strengthening the anti-seepage and anti-crack of cement concrete.

    Application fields of basalt fiber geogrid:

    1. Strengthen the soft foundation of high-grade, heavy-duty roads and dams, and isolate different foundation soil materials.  

    2. Reinforcement of various foundations.

    3. Strengthening and repairing of construction projects. the

    4. Suitable for cold areas such as the north where the temperature is low and the freezing season is long

    What are the advantages of basalt fiber geogrid compared with other material fibers (glass fiber, polyester fiber):

    (1) High tensile strength and low elongation.

    (2) Stable physical and chemical properties, can well resist biological erosion and climate change

    (3) No long-term creep.

    (4) Good thermal stability: the melting point of basalt fiber is above 1500°C, and the long-term use temperature is between -260 and 650°C, which ensures the stability of basalt fiber geogrid under high temperature during paving operations.

    (5) Anti-fatigue cracking.

    (6) High temperature rutting resistance.

    (7) Resistance to low temperature shrinkage cracking.

    (8) Compatibility with asphalt mixture.

    Raw material - basalt fiber introduction:

    The basalt continuous fiber material is known as "the new material of the 21st century". The basalt ore is used as the raw material, and the ore is crushed and put into the furnace. Crude fiber, and then the crude fiber is drawn into continuous fibers of various specifications by a wire drawing machine, and is infiltrated with different sizing agents according to subsequent uses, and processed to form products. the

    Compared with other high-performance fibers such as glass fiber, carbon fiber, and aramid fiber, basalt fiber not only has good mechanical properties, but also has many excellent functions, such as good high temperature resistance, and can work continuously in the range of -260 ~ 700 ° C; Alkali, strong UV resistance, low moisture absorption, better environmental resistance; good insulation performance, good high temperature filterability, radiation resistance, etc. Therefore, basalt fiber is a low-cost substitute for carbon fiber, and it is the fourth largest high-tech fiber after carbon fiber, aramid fiber, and high molecular weight polyethylene fiber.
