Description

Technical Field

[0001] The invention relates to the technical field of nondestructive material testing, and in particular to an online testing device for a double-layer translucent conduit used in an aviation oil pressure system. Background Art

[0002] Aviation oil pressure systems and aviation hydraulic systems usually use polytetrafluoroethylene conduits as fluid transmission pipelines. Polytetrafluoroethylene is a polymer material with excellent performance. It is widely used as high and low temperature resistant, corrosion resistant materials, insulation materials, anti-stick coatings, etc. in machinery, aerospace and other industries. Polytetrafluoroethylene extrusion molding technology, also known as paste extrusion molding, is one of the important methods of polytetrafluoroethylene molding. Its basic principle is to mix polytetrafluoroethylene dispersion resin with organic additives to form a paste, and then use a push press to push the paste into shape, and then go through drying, sintering and other process steps to finally obtain a product of the desired shape.

[0003] In the fields of medicine, chemical industry, aerospace, etc., the requirements for tubular materials such as catheters are not limited to basic properties such as corrosion resistance and high temperature resistance, but also require good biocompatibility, flexibility, and specific mechanical strength. It is in this context that the push-molding technology of polytetrafluoroethylene double-layer catheters came into being. Through push-molding technology, polytetrafluoroethylene catheters with double-layer structures can be prepared. This kind of catheter not only inherits the excellent properties of polytetrafluoroethylene, but also through the design of double-layer structure, it can further improve its mechanical strength, flexibility, conductivity and biocompatibility.

[0004] During the push-molding process of the polytetrafluoroethylene double-layer catheter, because its production process involves multiple links and real-time control of multiple parameters, it is very easy to produce small, imperceptible inclusions, bubbles, uneven thickness and other defects between layers. Such defects will cause the performance of polytetrafluoroethylene double-layer catheter products to drop significantly in special usage scenarios, resulting in irreparable losses. At present, the online detection methods for such production defects are very limited. The detection methods of most polytetrafluoroethylene double-layer catheter product manufacturers still remain at the stage of manual visual detection, with slow detection speed and high missed detection rate. Therefore, the present invention proposes an online detection device for double-layer translucent catheters for aviation oil pressure systems. The detection device has the characteristics of non-destructive testing and will not cause any damage to the material. In addition, it can provide high-resolution detection results, can accurately identify tiny defects, and generate real-time images, which are convenient for rapid analysis and decision-making. Summary of the invention
