Problems solved by technology

[0002] With the rapid development of my country's electric power field, there are various pipe materials currently used in electric power protection, and electric power protection tubes are important components in the electric power field. PET, PVC, PE, PP and other materials, among which, PET materials are widely used due to their good wear resistance, strong plasticity, good solvent resistance, good surface scratch resistance, good crack resistance, and good mechanical and physical properties. , but the melt strength, dimensional stability, barrier properties, heat resistance and other properties of PET materials are still insufficient; in addition, most of the current power protection pipes are pipe materials of various colors, and it is difficult to know the inside and outside of the pipe in real time through the pipe in practical applications. In the case of wire and cable, the practicability is low
