FRP Bolt: GFRP Bars

Product Description:

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:

FRP Bolt Glass  reinforced  plastic  anchor  rod

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.

FRP Bolt Glass  reinforced  plastic  anchor  rodFRP Bolt Glass  reinforced  plastic  anchor  rod

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.

Q:Plastic or better glass fiber reinforced plastic better?
Plastic steel profiles referred to as plastic, the main chemical composition is PVC, so also known as PVC profiles. It is a new type of building material which is widely used. Because of its physical properties such as rigidity, elasticity, corrosion resistance and excellent aging resistance, it is usually used as a good substitute for nonferrous metals such as copper, zinc and aluminum.In housing construction is mainly used for the application of push and pull, flat open doors and windows, rails, pipes and ceiling materials, through the process of the new protection board is also widely used in automobile engine, not only light weight, excellent properties and good toughness, stiffness.
Q:What does M23 grade of glass fiber reinforced plastic section mean?
The basic components of the FRP profiles for resin and glass fiber (including cloth, mat etc.), which is based on the fiber (including glass fiber, carbon fiber, organic fiber and other metal and non metal fiber) as reinforcing material, resin (mainly epoxy resin. Polyester resin, phenolic resin) as crosslinking agent, auxiliary and other supporting materials (mainly accessories: release agent, curing agent, catalyst, sealing mould agent, light stabilizer, UV clean water, gel coat) composites. It has a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, small specific gravity, low moisture absorption, small elongation and good insulation.
Q:Is the test standard for FRP pultruded profiles and FRP gratings the same?
Not the same. You can consult Hao Hao testing company (national level)
Q:FRP pultrusion process?
Pultruded glass steel is mainly using unsaturated polyester resin, Yuezhanla extrusion molding process more than 90% in addition to the amount of resin, epoxy resin, vinyl resin, thermosetting resin, propionic acid modified phenolic resin, flame retardant resin etc..
Q:Will the FRP section crack for a long time?
Under normal circumstances, glass fiber reinforced plastic profiles will not appear cracking phenomenon, if there is cracking phenomenon, may be the following reasons:1, the placement method is incorrect, such as irregular, non closed section of a large number of stacked2 、 the resin content in the profile is low, filling is more (see if the section color is whiter, and more powder fall off at the same time)
Q:How to install GRP mark pile
The possibility of theft (because of the pultruded glass steel material is square or triangle pipe is hollow know who stole 1. useless also know this thing is not plastic can not sell 2. take home cushion not after all not solid no component)
Q:What are the circumstances in which the pultrusion should be performed?
(1) the tensile strength of high strength extruded profiles for 150 ~ 300MPa, the bending strength reached 200 ~ 300MPa, the 1000h accelerated the bending strength after aging the retention rate of up to 78%.(2) the deformation rate is low. The length of the glass reinforced plastic pultruded section is accelerated by 1000h and the width change rate is +0.03%. The width change rate is -0.07%.. Therefore, the geometry and size of the product made of this pultruded section can be stable for a long time
Q:The manufacturing process of FRP products?
1, hand paste production method; 2, spray forming method; 3, fiber winding process; 4, molding process and molding process; 5, pultrusion method.
Q:What are pultrusion materials used for?
Various sections of Glass Fiber Reinforced Plastic Pultruded sections can be produced with different sections of the die. The profile has the characteristics of high strength, corrosion resistance and light weight
Q:Do you have any high temperature resistant resin made of pultruded glass fiber reinforced plastic?
Process formula of high temperature epoxy resin pultrusion adhesive
