Processing method of steel wire reinforced polytetrafluoroethylene spiral tube component

Abstract

The invention relates to a polytetrafluoroethylene spiral tube component, in particular to a steel wire reinforced polytetrafluoroethylene spiral tube component and a processing method thereof. The polytetrafluoroethylene spiral tube component is formed by assembling stainless metal connecting pieces at two ends of a sinusoidal spiral tube, and wrapping a reinforced jacket of stainless steel wireat the outer layer. The preparation method comprises the following steps: the polytetrafluoroethylene resin is pushed, pressed and sintered into polytetrafluoroethylene straight blank tubes, and thenthe polytetrafluoroethylene straight blank tubes are prepared into the polytetrafluoroethylene spiral tube component through forming, end recovery, nesting cutting, wrapping the reinforced jacket of stainless steel wire and head assembly. The prepared polytetrafluoroethylene spiral tube component is characterized by high-temperature resistance and low-temperature resistance, corrosion resistance,ageing resistance, light weight, excellent bending performance and the like, and is an ideal protective tube for wires and cables used for aero-spacecrafts and aircrafts.

Description

Processing method of steel wire reinforced polytetrafluoroethylene spiral pipe assembly technical field The invention relates to a polytetrafluoroethylene spiral pipe assembly, in particular to a processing method for a steel wire reinforced polytetrafluoroethylene spiral pipe assembly. Background technique At present, metal pipe assemblies, polytetrafluoroethylene or other engineering plastic hose assemblies have been used for connecting and protecting pipelines of lines such as electric wires and cables. As a protective pipeline for aerospace and aviation aircraft wires and cables, it should have the characteristics of high and low temperature resistance, corrosion resistance, aging resistance, light weight and excellent bending performance. Although the metal tube assembly has the characteristics of high and low temperature resistance, its shortcomings of heavy weight and non-distortion performance make its application limited. Similarly, PTFE hose assemblies have the d...

Problems solved by technology

Although the metal tube assembly has the characteristics of high and low temperature resistance, its shortcomings of heavy weight and non-distortion performance make its application limited. Similarly, PTFE hose assemblies have the disadvantages of heavy weight and poor bending performance.

Other engineering plastics, such as polyvinyl chloride, polyethylene and other hose components, are also subject to considerable restrictions in the aerospace field due to their poor performance in temperature resistance and aging resistance.
