The relationship between FRP pultruded profile and FRP guardrail

图片
FRP pultruded profiles   are generally made of polyester resin, surface mat, continuous mat and glass fiber, etc., which are cured at high temperature through a pultrusion process with constant cross-section structural profiles. There are many types of FRP pultruded profiles , such as FRP pultruded round tubes, FRP pultruded square tubes, FRP pultruded rectangular tubes, FRP pultruded round bars, FRP pultruded I-beams. The pultrusion process is a special process in the FRP forming process. It is suitable for the production of FRP pultruded profiles with various cross-sectional shapes. It is to impregnate untwisted glass fiber roving and other continuous reinforcement materials with resin, and then maintain a certain It is a composite material production process of forming a pultrusion product by forming a molding die with a cross-sectional shape and making it solidify in the die and then continuously exit the die   The glass fiber reinforced plastic square tube or round tube ...

Crack Resistance Of FRP Grating

图片
FRP grating is widely used, you can often see in daily life, many customers in the choice of FRP grating, will ask how the crack resistance of FRP grating, the next by FRP grating factory for you to carry on a professional explanation: FRP grating is different from wooden plate and metal plate. FRP grating has strong ductility. It is not prone to rupture or deformation when subjected to sufficient high operating pressure. The ductility is strong, so the relative anti-cracking fiber working ability is high. Although the anti-cracking fiber working ability does not significantly improve the overall bearing capacity of the plate, the relative reliability is much higher. FRP grating is a kind of unsaturated aliphatic polyester resin with glass fiber reinforced plastic anti-corrosion chemical fiber, after production and processing and make it a more Spaces of plate tectonics, because among them with glass fiber, thus has very good corrosion resistance, also prompted in some often very easy ...

The advantages of FRP grating plate in sewage tank

图片
The  FRP grating  plate in sewage tank is a kind of unsaturated polyester resin (including benzene, benzene, vinyl, and phenolic resin, etc.) as the matrix, with glass fiber roving as the skeleton in a customized mold through a special process with a certain opening rate of the plate material. Scope of application of FRP grating plate: Granary slope passages, tank top, the power plant water treatment workshop, drain cover plate, well cover, sewage treatment plant, car wash glass fiber reinforced plastic grille, washing drainage board, ski resorts, FRP FRP stand sidewalks, fence, along with the metro lines FRP plank road maintenance, yacht dock, landscape bridge deck, glass fiber reinforced plastic cable support, found board, municipal construction, afforestation trees grille, industry Plant operation platform, lawn isolation belt, lawn isolation belt, boat deck. Performance of  fiberglass grating plate  in the sewage tank 1.wear-resistant skid performance is outstand...

Characteristics and application of FRP grating

The main advantages of FRP grating cover plate are as follows: 1, FRP grating cover plate corrosion resistance Different resin properties give different corrosion resistance of FRP, so that it can be used for a long time in the corrosive environment of different acid, alkali, salt, organic solvent, gas and liquid medium. 2, light and high strength The perfect combination of alkali-free glass fiber yarn and resin gives the product unique characteristics of light weight and high strength, the proportion of the product is 1/4 of steel, suitable for various bearing structures in corrosive environment. 3, glass fiber reinforced plastic grille cover plate aging resistance The product is made of high quality matrix resin and anti-aging additive, so that the product has durable anti-aging performance, can maintain long-term light and sustained high strength, and the service life is more than 20 years. 4. Designability In addition to the flexible design properties of FRP, the color of the produ...

How to identify the raw materials of FRP pultrusion profiles

图片
The raw material of FRP pultrusion profiles is generally resin and FRP fiber, and then it is a colorless and transparent material, which should have low viscosity and low heat release performance. Some of the characteristics of FRP pultrusion profiles are indispensable. The FRP profiles produced are smooth and smooth, with good gloss, high strength, and toughness. If the use of inferior resin will be completely opposite inferior resin turbidities, high viscosity, high heat release, high shrinkage, relatively slow curing, compatibility is poor, the production of FRP profiles with pores, easy to fracture, poor strength and toughness. The second is the comparison of finished products. Good FRP profile products have no obvious cracks, fewer pores, bright and pure color, good transparency, a certain toughness and strength, good surface finish, long service life; The appearance of inferior FRP products has cracks, more pores, color impure gloss is not enough. Its service life is also short. ...

The Differences between Fiberglass and Carbon Fiber

  Fiberglass : It is a kind of inorganic nonmetallic material with excellent properties. Glass balls or waste glass as raw materials after high melting, drawing, winding, weaving, and other processes, the final formation of glass fiber, glass fiber diameter from a few microns to more than 20 meters between microns, equivalent to a hair 1/5 to 1/10 diameter, a bundle of fiber are composed of hundreds of monofilament. Characteristics of glass fiber: It is generally considered that glass is a brittle hard object and is not suitable for structural use. However, if it is drawn into silk, the strength will be greatly increased and has softness, so it can become an excellent structural material after changing shape with resin. As the diameter of glass fiber decreases, its strength increases. These characteristics make the use of glass fiber far more extensive than other types of fiber. Glass fiber has the following characteristics: High tensile strength; High elastic coefficient; High imp...

Chemical Factory Fiberglass Grating

  More and more factories have realized the advantages of  FRP grating   application, especially in chemical plants. Because of the special corrosive environment of chemical plants, the corrosion resistance of factory components is required to be high. In this paper, we understand the three reasons for chemical plants to choose fiberglass grille.   Many chemical plants use fiberglass grille as the pavement material to make the operating platform, because of its lightweight, compared with steel, three-quarters of the weight, so the installation does not need to use lifting equipment, as the operating platform supported on the equipment is more suitable.  Fiberglass grating cutting is very convenient, the use of an arc cutting saw can be very convenient to open the hole to meet the requirements of installation equipment, and will not cause the change of mechanical properties of the grid due to the opening, not to cause the scattered grid.  For mobile operatin...
