FRP grating is a new type of material encouraged by the state. FRP grating colors include: yellow, green, gray, red, blue, black, natural. The FRP grating is made of a molding process and has a number of regularly distributed rectangular and square-spaced FRP sheets with two-way homogenous mechanical characteristics. Can be widely used in petroleum, chemical electronics, power, paper, printing and dyeing, electroplating, marine exploration, sewage treatment and other industries, such as work platforms, equipment platforms, drilling platforms, walkways, etc., is an ideal product in a corrosive environment, but also suitable for Civil building facilities. This series of products are: crescent face, sand face, double plane, flat grille and so on. Its performance characteristics are: corrosion resistance: it has excellent corrosion resistance of many gas and liquid media such as acid resistance, alkali resistance, organic solvent resistance and salt resistance, and has incomparable superiority in anticorrosion field.
According to the requirements of actual use, it is economical to choose the use of o-benzene type, meta-benzene type, vinyl type resin as the base material. It is light and high: the density of FRP grating is not more than 2, only 1/4 of steel, 2/3 of aluminum, its strength is 10 times that of rigid PVC, and its absolute strength exceeds that of aluminum and ordinary steel. Level, anti-aging: service life is more than 50 years; flame retardant: ordinary flame retardant grille flame propagation rate (ASTM E-84) does not exceed 25, high flame retardant vinyl grille flame propagation rate does not exceed 10, oxygen The index is not less than 28 (GB 8924); it has excellent electrical insulation in terms of safety, no breakdown at 10KV, no electromagnetic, and can be used on magnetic sensitive equipment. The special structure of FRP grating also has anti-skid and anti-skid resistance. Characteristics such as fatigue.
Glass fiber reinforced plastic grille, also known as FRP grating, originated in the United States in the 1970s. It is made of glass fiber as a reinforcing material, unsaturated polyester resin as a matrix, and molded by glass fiber interlaced woven resin. The article consists of a number of symmetrical lattices with bidirectional isotropic features in the longitudinal and transverse directions. The characteristics of the FRP molded grid are as follows: the glass fiber interlaced and the resin are fully impregnated to maximize the corrosion resistance of the grid; the overall structure of the grid distributes the load on the longitudinal and transverse grids; The load is dispersed on the adjacent longitudinal and transverse grid bars, which contributes to the uniform force of the grid and the supporting structure; the resin-specific luster surface and the inclined grid surface make the grid self-cleaning; the pure resin concave surface makes the grid With anti-slip properties, the sanding surface has better anti-slip effect.
