FRP Anchor Application?

FRP anchors are formed by extrusion, pulling and high temperature curing of glass fiber yarn, resin, curing agent, etc. The glass fiber generally accounts for the total weight of the rod body, so the main performance of the FRP anchor is mainly determined by the glass fiber. Since glass fiber is an elastic material with brittle characteristics, the resin selected for glass fiber anchor is generally thermosetting resin, so the elongation of glass fiber anchor is very small.

Because the glass fiber is unidirectionally arranged in the glass fiber anchor, its tensile strength is relatively high, but its shear, torsion and bending strength are low. The shape of the anchor body is full thread, and the thread is left-handed or right-handed. It has high tensile strength, easy cutting, no damage to picks, no sparks, high coal mining efficiency, light weight, high corrosion resistance, flame retardant, antistatic properties, long-term support, and is a composite replacement for metal anchors. Reinforced material new products.

(1) The shearer will generate sparks when it encounters the steel anchor rod during the coal cutting process, and there is a hidden danger of coal dust stability; the glass fiber reinforced plastic anchor rod has the characteristics of explosion-proof and anti-static, and no sparks will be generated during cutting, which is very conducive to the stability of the roadway Construction, especially suitable for high-concentration areas; where can fiberglass anchors be used?

(2) The cut waste steel bar anchors are mixed into the coal, and it is easy to hurt and damage the equipment. FRP anchor is an easy-to-cut composite material that protects the cutter head of the shearer;

(3) The FRP anchor has high bearing capacity, strong tensile capacity, and the strength of the rod body is better than that of threaded steel of equal diameter, which can be used as a long-term support;

(4) FRP anchors have excellent properties such as convenient cutting, anti-static, corrosion resistance, etc., and can replace steel anchors and become an ideal material for coal support.

According to the characteristics of FRP anchors, it can also be used for coal mine roadway protection, underground engineering such as mines and railways, tunnel anchor support, railway, highway and other slope anchor support, mine roadway and underground engineering surrounding rock support. It can ensure the stability of mine roadway and surrounding rock of underground engineering.
