Adhesives performance of 3-layer PE pipe coatings: Effects of MAH loading, PE particles size, coating interval time and service temperature

Ultrastrong bonding, on-demand debonding, and easy re-bonding of non-sticking materials enabled by reversibly interlocked macromolecular networks-based Janus-like adhesive

“…Integrating hydrophobic and hydrophilic materials by means of adhesion is highly desired for a vast range of applications, such as polytetrafluoroethylene-coated metal non-stick pans, 1 polyethylene-lined steel pipelines, 2 composite building panels made by sandwiching polyethylene between aluminum sheets, 3 and polyolefin roofing membrane attached to gypsum board. 4–6 As single-component adhesives are not suitable for these purposes, hybrid adhesives mostly consisting of copolymers have to be introduced in the form of a layered assembly with the aid of surface treatment to satisfy the distinct requirements of the chemically divergent adherends (also called substrates).…”

Producing Microlayer Pipes and Tubes through Multiplication Coextrusion and Unique Annular Die: Simulation and Experiment

“…Tubular structures with multilayer annular structures (MAS) have been widely used in many applications, for example, as multilayered bubbles in blown films, , as a multilayered coating on wires and cables, as multilayered parisons for blown molding, and as multilayered tubes and pipes. , MAS is currently produced by a multimanifold die, in which the individual layer forms in separate manifolds and then joins together before the exit of the die . So, designing and manufacturing a multimanifold MAS die becomes rapidly complex with each added layer, putting a limit on the layering capabilities, and thus the typical MAS only includes 2–12 layers .…”

Effects of stray AC on corrosion of 3-layer polyethylene coated X70 pipeline steel and cathodic delamination of coating with defects in 3.5 wt-% NaCl solution

“…In order to protect the pipelines against corrosion to avoid any production failures, the coating system is widely used. 3-layer polyethylene (3PE) pipeline coating system, as one of the most used pipeline coating systems, can provide excellent corrosion protection [19]. However, the coating itself is affected by electrical interference, which may affect its performance [20].…”
