AI Technical Summary
Existing PE pipes have insufficient flame retardant and antistatic properties under high temperature and high pressure, and the preparation method has problems such as uneven mixing, low density, and poor pipe dimensional accuracy.
The flexible hydrogen transport PE composite pipe adopts a three-layer structure design. The inner lining layer and outer protective layer are made of high-density polyethylene, antistatic agent and flame retardant, and the reinforcement layer is carbon fiber. Through carbon fiber pretreatment, filler pulping and co-extrusion molding process, a core-shell structure and carbon fiber mesh reinforcement layer are formed to improve compatibility and dispersion uniformity.
While improving the flame retardant and antistatic properties, it also enhances the mechanical properties of the pipe, ensures the density and dimensional accuracy of the pipe, reduces costs, and adapts to complex use environments.
