AI Technical Summary
Technical Problem
FRP fence pultrusion is prone to peeling and cracking during the process of pultrusion, which affects its appearance and performance.
Method used
A process is adopted, including setting up a high-power heater in the preheating zone of the heating and curing device to increase the temperature, using a semiconductor refrigeration sheet to quickly cool down the heat dissipation zone, adjusting the traction speed of the traction device to extend the resin curing time, and performing line shutdown cleaning on the production line.
Benefits of technology
It effectively reduces the risk of peeling and cracking, improves the corrosion and impact resistance of fiberglass fences, thereby extending its service life.

Abstract
The invention relates to the technical field of glass fiber reinforced plastic fence pultrusion processes, and discloses a glass fiber reinforced plastic fence pultrusion process capable of reducing peeling and cracking, and used equipment mainly comprises a material conveying device, a resin dipping tank, a pre-forming device, a heating curing device, a traction device and a cutting device. Impregnating in a resin impregnating tank, continuously transferring by using a preforming device so as to ensure the relative positions of the resin impregnating tank and the preforming device, curing by using a heating curing device, pulling the cured glass fiber reinforced plastic fence, and cutting the glass fiber reinforced plastic fence section according to the required length; through the process, when cured resin particles are prevented from being discharged from the mold, cracking and stripping caused by overheating are reduced, and the problem of stripping or falling off is solved.
