AI Technical Summary

Technical Problem

Existing technologies struggle to achieve a synergistic improvement in high thermal conductivity and strong corrosion resistance of polymer composite pipes under high temperature, high humidity, and highly corrosive media, and it is difficult to maintain good processability and mechanical strength under ultra-high filling conditions.

Method used

Using polyphenylene sulfide as the matrix and composite graphite filler as the thermally conductive reinforcing phase, and introducing corrosion-resistant modifiers, lubricants, and processing aids, a three-dimensional continuous thermally conductive network and corrosion-resistant barrier are constructed through specific surface modification, melt blending, and extrusion molding processes. Combined with gradient cooling and plasma treatment, polymer composite pipes with high thermal conductivity and strong corrosion resistance are prepared.

Benefits of technology

It maintains high thermal conductivity (≥15 W/(m·K) and high strength (tensile strength ≥18 MPa) in strong acid environments, and operates stably for a long time under complex flue gas conditions, reducing the coefficient of friction and the adhesion rate of ash and dirt, making it suitable for deep waste heat recovery systems.
