The FRP grille products produced by the FRP grille manufacturers are new products made of resin and glass fiber composites. The main feature is strong hardness, at the same time preparing pressure resistance, and stable function during the application. The FRP grille device is used. No special maintenance is required for hours and hours, which is more convenient for customers. FRP grille technology: FRP grille is a kind of simple process. It uses extrusion equipment. It has a wide range of materials. It can use fiber, braid or felt. Its component can be glass fiber, and Aramid fiber, carbon fiber or other fiber materials.The FRP grille uses pultruded "I" and "T" shaped profiles as load-bearing strips, solid pipes or rods as connecting rods, and boards with open space made by a certain installation process. The pultrusion process of glass fiber reinforced plastic grid manufacturers is based on the untwisted glass fiber roving, glass fiber felt and other reinforced materials. Under the traction of the pultrusion molding machine, the resin is impregnated through the resin bath, and then the glass fiber reinforced plastic profile is produced by the molding die. Molding. During the pultrusion of FRP grid manufacturers' products, the fibers first pass through a thermoforming die of the same size as the FRP product, and then enter a drawing mechanism.Between the creel and the forming die, a rubber groove is set, in which a resin made in advance is placed, and the fibers are impregnated with the resin to be arranged by a guide device, and then enter the forming die.The guide device is provided with a round hole or slit to remove excess resin stuck on the fiber.The temperature distribution of the molding die is carefully designed to ensure that the resin has completed the curing process when the pultrusion material leaves the rear port of the FRP pultrusion die.An air cooling section is provided in front of the drawing mechanism and the cutting machine to cool the pultruded products with a relatively high temperature. The glass fiber reinforced plastic grid injection pultrusion process has the following two advantages: one is that the resin component is more accurate and can be continuously measured by a metering pump to prevent errors caused by manual mixing; the other is that the resin impregnation tank changes from an open form The fully enclosed form greatly reduces the possibility of resin splashing, and then improves the operating environment of the pultrusion process.
