Production method of plastic pipe in layers |
| abstract |
The object of the invention is a method to produce plastic pipe where a pipe of two or more layers is extruded and where at least one layer has additive that by heat treatment releases free radicals. Immediately after the extrusion, the pipe is heat treated by leading it either through a hot salt bath or an infra-red radiation so that the mentioned additive decomposes. Now, the layer(s) having additive get cross-linked and additionally the crosslinked layer(s) fix with chemical bonds to at least one other layer. n With this method it is possible to produce a plastic pipe where there is no need to use a separate adhesion plastic layer to fix to each other layers that reject each other. |
