| 摘要 |
The present invention relates to a method for manufacturing a pressure container comprising an inner liner layer of polymer material, such as polyolephines or a similar material, and an outer, fibre-reinforced and pressure supporting layer, characterized by treatment of the outer side of the inner liner layer so as to increase the wetting and adhesive properties of the polymer material, employing an adhesive at the outer side of the inner liner layer and/or in direct contact between the outer side of the inner liner layer and the inner side of the outer fibre-reinforced, pressure supporting layer, and winding of the outer, fibre-reinforced and pressure supporting layer onto the inner liner layer. In a preferred embodiment the treatment of the outer side of the inner liner layer comprises flaming, but also corona-discharging, possibly in combination with ozone treatment, or a corresponding method for improving the wetting and adhesive properties of the polymer material can also be employed.
