| titleOfInvention | Die for extrusion and inner coating method thereof |
| abstract | Provided are a die for extrusion molding and an inner coating method thereof for forming a crosslinked polyethylene pipe. The die for extrusion molding according to the present invention includes an outer shell tube 21 and an endothelial tube 22 that are separable from each other, and the inner tube 22 also includes a flange 221 and a pipe 222 that are separable from each other. By this structure, when the coating layer formed on the inner surface of the endothelial tube is damaged by the molding operation, the endothelial tube 22 can be separated for regeneration thereof, thereby facilitating the removal of the damaged coating layer and the formation of a new coating layer. When the inner diameter is expanded beyond the allowable range by repeated formation and removal of the coating layer on the inner surface, only the pipe 222 can be replaced to save the cost for the extrusion. In addition, the die for extrusion molding according to the present invention has a fluororesin coating layer formed by coating and sintering by using an fluororesin powder on the inner surface of the endothelial tube by electrostatic coating, and the coating layer has excellent durability. |
