When the PP power pipe is used for construction, a large amount of excavation is not needed, molded roads, railways, buildings, riverbeds and the like are not needed to be destroyed, construction projects such as pipelines and cables can be directly carried out in the special sections, and compared with a traditional pipeline laying mode, the PP power pipe is more environment-friendly.
PP resin has better mechanical property, but has lower rigidity and modulus, especially lower heat distortion temperature, and the weak points are difficult to meet the requirements of engineering materials. Therefore, the reinforcing, toughening and high-temperature-resistant modification of the PP material can be realized by adding fillers such as inorganic particles and glass fibers or blending the fillers with high-temperature-resistant engineering plastics such as PPO (polyphenylene oxide) and epoxy resin.
The MPP power pipe has the following distinct features: the electric insulation performance and the low-temperature impact performance are excellent; the tensile and compressive properties of the composite material are higher than those of HDPE; the material is light, smooth and low in friction resistance, and can be butt-jointed by hot-melt welding; the external temperature for long-term use is-5 to 70 ℃. The power tube made of the common PP material produced by the prior art is brittle, the bending modulus and the tensile strength of the material are small, the heat deformation temperature of pure PP resin is about 110 ℃, and the pure PP resin can actually resist about 100 ℃ for a long time, so that the application and the popularization of the PP power tube are limited by the defects.
