Fiberglass reinforced plastic (FRP) characteristic and function marker posts are commonly used in the installation of field lines in power, mobile, telecommunications, railways, highways, mines, gas pipelines, oil pipelines and other departments to serve as a warning. These units can help in line construction and maintenance, and can work effectively in a short time. Performance characteristics of glass fiber reinforced plastic marker posts: 1. Material of glass fiber reinforced plastic marker posts: molded high-strength glass fiber composite (recycled and useless). 2. The text on the surface of the FRP marker post product is processed with special silk screen and concave shape, and is colored and solidified once. 3. Glass fiber reinforced plastic marker posts have bright colors and good strength, and their service life can reach more than 30 years. 4. Glass fiber reinforced plastic marker posts are truly maintenance free. Unlike cement, stone and other materials, they need to be painted and sprayed regularly every year, saving maintenance labor costs. The text on the product surface is hard and durable. It can also be customized one by one according to the stake number, mileage, path direction arrow, maintenance telephone and other information provided by the user unit.
Differences between GRP marker posts and other marker posts:
: The materials are different (the GRP marker post is made of square or triangular tubes extruded by pulling, which are processed and printed or engraved with a engraving machine and then covered). Concrete (that is, it is OK to use concrete for direct brushing)
Second: the life of the font (because the FRP marker post material needs polishing and polishing before printing, so the printed font can stay longer than the concrete one)
Third: the possibility of theft (because the FRP is made of pultruded square tubes or triangular tubes that are hollow). The FRP marker posts are solid, strong in impact resistance, and have a service life of 30-50 years.
The pile body color is common and white. Compared with the cement marker post, the reinforcement embedded in the cement marker post is easy to be stolen, and the FRP material has no recycling value, so it can prevent theft
Glass fiber reinforced plastic marker post is pressed at high temperature. Impact resistance, abrasion resistance, high temperature resistance, corrosion resistance, resistance to water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compounds, asphalt, suitable for various acid-base soils. The service life is up to 30 years. The content adopts screen printing technology, with good warning effect and no need for maintenance. Light weight, convenient for transportation and installation. No recycling value, natural anti-theft.
Resin Gaza marker post: made of resin Gaza. High temperature die is formed once, which is impact resistant, abrasion resistant, high temperature resistant, corrosion resistant, and has a service life of up to 50 years. The surface is etched, and the font and pattern are clear and beautiful. Anti theft. It is a product that takes into account the advantages of fiberglass marker posts and cement marker posts.
(1) The insulation material and insulation resistance can prevent electric leakage, maintain good dielectric performance at high frequencies, do not reflect, do not block the transmission of microwave, and do not rust. Long term use is safe
(2) Good corrosion resistance, resistance to water, gasoline, alcohol, asphalt, suitable for various acid-base soils, rain proof, the product itself has good performance, and the surface of the product has a protective layer of UV resistance, dual protection makes the product have higher performance.
(3) The marker post has strong impact resistance, no deformation upon impact, high tensile strength, bending strength and impact toughness, with a specific gravity between 1.9-2.0, which can completely meet the requirements of outdoor use safety, and has good impact resistance. Our series of marker posts are impact resistant, wear resistant and high temperature resistant Corrosion resistance, so the service life is up to 30 years.
(4) The marker post has no harmful substances and is currently a domestic material.
The glass fiber reinforced plastic material adopts Huang color for the pile body and red color for the hat! Other colors can also be allocated to customers according to their requirements
Maintenance method of glass fiber reinforced plastic (GRP) marking steel - the maintenance method is the marking used on cable and gas pipeline equipment, which mainly serves as a reminder. Due to its use environment, the product has a beautiful appearance, can be made into various colors, with clear font and pattern, and also plays a role in beautification. The product is made of new unsaturated resin material by high temperature pressing. In the process of processing, all processes can achieve the goal. Therefore, the quality of the product is fundamentally achievable, and the impact resistance and wear resistance are high. The outdoor installation effect is good, which is more suitable for outdoor wind and rain. Sign post GRP railway is an effective replacement product of cement warning post

Working principle of molded FRP marker post
According to the test of the Ministry of Communications on the adhesion of reflective film to the sign base plate, 5 minutes after the test, the stripping length of the reflective film is 3-4 mm, which is much smaller than the standard requirement of 20 mm. Molded FRP is formed under high temperature and pressure, with good mechanical strength and uniform force in transverse and longitudinal directions. The strength is above 80Mpa. The aging of GRP materials in the atmosphere is mainly caused by the mechanical effects of the sun, high temperature, humid air and wind and rain, which causes the resin on the surface of GRP to fall off, expose white filaments, and lose weight. At the same time, ultraviolet light irradiation degrades and oxidizes the active substances, making the color of GRP yellow. For the above phenomenon, add anti-aging agent. Only a small amount of styrene gas. The chopped strand mat or glass fiber coarse fiber is laid on the PE film evenly coated with resin paste in advance, and then covered with another layer of PE film coated with resin paste, forming a "sandwich" structure. When passing through the impregnation area, the resin paste and glass fiber (or felt) shall be fully kneaded, and then collected into rolls for necessary aging treatment. After the finished sheet is free from sticking, it can be cut to a certain size as required, the PE film on both sides can be removed, and it can be stacked in the metal die for heating and pressure forming as required. At present, sheet molding compounds are mainly formed by pressing metal against mold, and the process is very simple.
