Method for producing DTX carbon fibre cable protecting and leading pipes

Abstract

The invention relates to a preparation method for a DTX carbon fiber protect lead tubular product. The product uses HDPE high density polyene and modification carbon elements as raw materials. The mould extrusion forming and the unique rotational forming technique are used for setting and producing the protect lead tube which takes on helix tube shape. As the invention uses the rotational technique, the cast has thin walls, saves materials and has light weight, and is convenient for transportation and construction. The helix shape is used in the method, which increases ring stiffness and has strong rigidity. Tough elasticity, namely, deflexion, effectively undertakes loading and is not out of shape. The ring extrusion technique is used in the method, which causes that the tubular product has excellent bending property, can bend at will, can avoid barriers, and is suitable for different topography and landform, constructed in an optimizing and reelability way. In addition, as the tubular product has longer length, has few adapters, thus saving a large number of labor power, physical resources, and financial resources. The tubular product has strong quake-proof capability, corrosion-resistance, high pressure-proof performance, good flame retarding effect and is convenient for installation and construction.

Description

Technical field: [0001] The invention belongs to the technical field of materials, and in particular relates to a method for preparing a DTX carbon fiber cable protective pipe material. This product is mainly used in the protection of optical cables, cables, and cable jackets, and is widely used in the expansion and transformation of power grids such as communications, electric power, urban construction, municipal, industrial and civil buildings, highways, and railways. Background technique: [0002] As we all know, the optical and cable jacket protection tubes currently used in the market are all made of CPVC, VPVC and glass steel pipes. These pipes are large in size, heavy in material, not easy to install and use, and because the pipes are hard and brittle, they are easy to break and have a short service life. Due to the rigidity, a bedding layer must be laid during construction, and laying the bedding into a horizontal surface not only wastes a lot of manpower, material r...

[0002] As we all know, the optical and cable jacket protection tubes currently used in the market are all made of CPVC, VPVC and glass steel pipes. These pipes are large in size, heavy in material, not easy to install and use, and because the pipes are hard and brittle, they are easy to break and have a short service life. Due to the rigidity, a bedding layer must be laid during construction, and laying the bedding into a horizontal surface not only wastes a lot of manpower, material resources, and financial resources, but also has a large contact surface with the cable when the cable is threaded, the frictional resistance is large, the cable skin is easily damaged, and its insulation performance is poor. Poor, no longer meet the needs of social development
