Problems solved by technology

[0002] At present, the conductive FRP anode tube is mainly produced by hand lay-up process, which has a low degree of mechanization, a long production cycle, and cannot be mass-produced. The labor intensity of the workers is high, and the product quality is determined by the degree of worker training. The quality stability is poor and there is a lot of waste.
Another production process of conductive glass fiber reinforced plastic anode tube - pultrusion process, through the continuous traction of the traction device, the fiber material impregnated with resin is first preformed in the mold, and then heated and cured. It is an automatic production process. High production efficiency, continuous batch production, stable product quality, no waste, but this process has strict requirements on the performance of raw materials, and the carbon fiber felt in the prior art is not suitable for the pultrusion process due to its low strength, which restricts the conductive FRP Development of Anode Tube Pultrusion Technology
