Features FRP pultruded profiles: 1. High strength: and the strength of steel similar to ordinary plastic four times the service life of 20 years 2. corrosion-resistant, maintenance-free: no rust, do not do paint every year, almost no maintenance fees. 3. The color variety, color and soft: and plastic like, you can have a variety of colors, easy to urban color design, no reflective stainless steel contamination. 4. Light: the proportion was only 1/4 of steel, easy installation and construction. 5. Security: FRP pultruded grating due to the sale of non-recyclable, reducing the possibility of theft criminals. Features and Performance 1. Good dimensional stability thermosetting resin matrix crosslinked network structure formed body is heated in the process occurs, the article is dimensionally stable under normal good, after the occurrence of shrinkage after molding is small. Products under long term continuous loading minimal changes its shape and size, i.e., creep is small. Creep performance depends on the size of its load, the temperature level and duration of load factors of time. At a fixed load and temperature conditions, creep after prolonged loading thermosetting plastics smaller than thermoplastics. 2. The superior heat resistance, high temperature properties of thermosetting resin matrix composites can not be cured and then soften, heat resistance, and its products fairly stable, with a load of 1.86MPa, generally heat distortion temperature within 150 ~ 260 ℃, The fiber-reinforced thermosetting plastics belong to excellent insulating material, whose thermal conductivity is generally 0.35 ~ 0.47W / (mK), only the metal of 1/100 to 1/1000, it can be used as good heat insulation material and moment resistance high-temperature materials, thermal deformation temperature of the material up to 350 ℃, can be used at room temperature and high temperature structural materials. Glass / phenolic rocket, missile engines excellent insulation. 3. The composite material is excellent in electrical properties of excellent electrically insulating material, mica filler terms of more excellent articles made their electrical properties, can be used to manufacture the arc resistance, resistance, voltage, excellent in specific inductive electrical components. Since the composite material has excellent electrical properties, and its products do not exist electrochemical corrosion and stray current corrosion, can be widely used in the manufacture instruments, motors and electrical insulating parts, in order to improve the reliability of electrical equipment and extend the life . In addition, the role of good products at high frequency and microwave dielectric properties of permeability has been used to produce a variety of high-frequency dielectric radome and other products. The excellent corrosion resistance resin matrix composites and electrochemical corrosion mechanism different from ordinary steel, it is not conductive, dielectric solution does not dissolve the ion, and thus the air, water and general concentration of acid, alkali, salt and other media have good chemical stability, especially in the non-oxidizing acid and fairly wide ph range of medium has good stability. Therefore, it is widely used in the manufacture of corrosion-resistant products, in order to deal with some of the media can not be used for stainless steel (such as hydrochloric acid, chlorine, carbon dioxide, sulfuric acid, sodium hypochlorite, and sulfur dioxide) corrosion, has played a good role. 5. FRP pultruded profiles good surface properties of the composite material is in contact with the chemical media generally have little surface corrosion generated few scaling, so commonly used manufacturing fluid conduit in its pipeline little resistance, low friction coefficient, saving a lot of momentum. Because composites are generally not as easy as the metal to form metal ion contamination media, so this is also widely used in the food and pharmaceutical industries composite products reason. In addition, the composite material has a high friction (pv) limits under water lubrication conditions, the friction coefficient is very small, about 0.01 to 0.03, it is also the preferred material wearable products. FRP pultruded profiles is fully impregnated resin mixture of continuous glass fiber, glass fiber roving, continuous mat, carpet surface materials such as reinforced by mold and heat cured in the mold cavity, tension in the traction mechanism Under continuous pull of unlimited length profiles. Pultruded profiles can be designed with a high resistance, various - pultruded profiles shaped by a combination of appropriate connection can be made a variety of FRP products in widely different fields should, as with the structure of its manufacturing platform , guardrail, ladder, grill, tents stents and other products, as a result of lightweight, high-strength, corrosion resistance, excellent performance and features, and is widely used in chemical corrosion, oil, non-ferrous metallurgy, electrical insulation, sports and tourism. FRP pultruded profiles, there are many, fiberglass pipe, fiberglass pipe, rectangular pipe fiberglass, fiberglass rod, glass and steel I-beam. The basic components of the FRP profiles for a resin and glass fiber (including cloth, felt, etc.), which is based fibers (including glass fibers, carbon fibers, organic fibers and other metals, non-metallic fiber) as a reinforcing material, resin (mainly epoxy polyester resins, phenolic resins) as crosslinking agent and other auxiliary materials supplemented (the main materials: mold release agents, curing agents, catalysts, closed mold release agents, UV light stabilizers, mold clean water, plastic clothing, etc. ) composite made of. It has a high temperature, corrosion resistance, high strength, low specific gravity, low moisture absorption, good extension and a series of small and excellent insulation properties.
