Item specifice

Bolt support in coal mines in recent years, railway, highway, water conservancy and urban construction engineering project, at the same time, the rapid development in the glass fiber reinforced plastic (GRP) anchor applied correspondingly, GRP anchor of safety and operability are far more than the metal bolt now used by coal mining, and is gradually replacing the traditional metal bolt, is the new alternative metal bolt supporting materials. Its advantages:

1, high strength, easy cutting rod body: the tensile strength of glass fiber reinforced plastic anchor rod is better than that of ordinary steel, higher than 20% of the steel bar, the same specification and good fatigue resistance performance, light weight, only for the same volume of steel 1/4. Its material is a composite material, easy cutting, can protect the coal winning machine cutting head;

2, safety performance is good, explosion-proof anti-static: thermal conductivity, conductive, flame retardant, antistatic, collision won't produce sparks, through the formula change and metal for tunnel safety construction is very good, especially suitable for gas concentration area;

3, Gao Jiangnai corrosion, high bearing capacity, tensile resistance is strong, the diameter of the rod body strength is better than that of rebar bolts, as a support for a long time, can resist erosion of chloride ions and low PH solution, especially the resistance to corrosion of carbon compounds and chlorine compounds is better.

4, material binding force strong: closer to the cement thermal expansion coefficient compared with steel, so the rod body with concrete grip of stronger;

Light 5, can design sex is strong, easy to operate, stable modulus of elasticity, thermal stress under the size stability, heat bending shape can be arbitrary shape, and weight is only 1/4 of coequal norms metal bolt, can be used in tight Spaces such as tunnels and mines is convenient, make it easier for the construction, reduce labor intensity;

6, construction is convenient, can produce all kinds of different cross section according to the requirement of the user and the length of the standard and non-standard, non-metallic drawstring tie available at the scene, the operation is simple.

Glass reinforced plastic anchor rod production equipment, our company is using the company independent research and development, after more than 10 years of market recognition, production research and development department improve MYC - 1200 pultrusion equipment, with completely independent intellectual property rights, more than 20 supporting patent technology, is a domestic initiative.

So far, our company has formed glass reinforced plastic anchor rod of raw materials, production equipment, glass fiber reinforced plastic anchor rod products production and sales of the whole industry chain, pultrusion technology, production, processing and application of full thread glass reinforced plastic anchor rod, the glass fiber content as high as 80%, at the same time because of pultrusion technology of prestressed effect, can greatly improve the strength of glass fiber reinforced plastic anchor rod body, tensile strength can be big, to ultra high strength bolt corresponding technical indicators. And can be installed directly nut, because the rod surface area significantly increase can significantly increase the anchorage rod body strength and tensile strength; Tray, nut supporting with tray, nut of invention patent.
