A production process of prestressed plastic steel PE composite pipe

Abstract

The invention belongs to the technical field of PE composite pipe production and relates to a production process of prestressed plastic steel PE composite pipe. The steps are: immerse and pass the fiber into the thermosetting resin mixture, pultrude and heat, solidify into plastic steel wire under tension, and roll it into a coil for later use; weave the plastic steel wire into a net with a braiding machine on the surface of the base pipe; Glue is dispensed at the nodes of the mesh; a PE layer is extruded outside the plastic steel wire mesh that has been dispensed to make a composite pipe. The invention prepares the PE composite pipe by replacing the traditional steel wire with the extruded glass steel wire or carbon fiber steel wire, which has the advantage of not rusting. The coefficient is close. After the production of the pipe, it will not be delaminated due to the tension of thermal expansion and cold contraction, and will not form stress on the structure of the pipe. It can be fixed at the intersection of weaving with a glue dispenser to ensure uniform distribution and ensure the quality and stability of the pipe. sex.

Description

Technical field [0001] The invention belongs to the technical field of PE composite pipe production and relates to a process for producing a prestressed plastic steel PE composite pipe. Background technique [0002] As a chemical building material, plastic pipe has the characteristics of low energy consumption, corrosion resistance, environmental friendliness and long service life. In order to improve the strength of plastic pipes and make them have high-strength and high-compression functions, composite pipe structures are usually used, that is, the inner and outer layers are made of polymer materials, and the middle layer is made of functional materials. The middle layer is generally made of metal mesh material. However, due to the prolonged use time of this kind of plastic pipe with a metal structure, it is inevitable that there will be water seepage inside the pipe, which will cause corrosion of the metal. The withstand voltage performance will have an impact. On the other ...

Problems solved by technology

[0003] The present invention proposes a new type of prestressed plastic steel PE composite pipe production process in view of the problems of the steel wire layer being easy to rust in the traditional PE pipe production process and the unstable pipe properties caused by the non-standard weaving of the steel wire mesh skeleton.
