description A non-corona hot ion stream injection and polarization method for treating the polyethylene outer sleeve of directly buried anticorrosion insulating tube features that before the hard foam plastics of polyurethane is foamed, the internal surface of polyethylene sleeve is heated uniformly in moving mode while hot ions stream is injected, and then it is quickly cooled for solidification. Its advantages are low cost and simple apparatus. The treated sleeve has high adhesion to hard foam plastics of polyurethane (360 KPa or more), high quality and long service life.
