Embodiment 1

[0025] The steel mesh skeleton composite pipe manufacturing process provided by the invention comprises the following steps:

[0026] (1) Feeding: Add 2% black master particles to the main material of granular polyethylene to make the inner and outer polyethylene pipe raw materials of the steel mesh skeleton composite pipe, and put the raw materials into the inner polyethylene pipe screw extruder respectively and the hopper of the outer polyethylene pipe extruder;

[0027] (2) Extrusion molding of the inner layer polyethylene pipe: the inner layer polyethylene pipe screw extruder extrudes polyethylene into the inner layer polyethylene pipe mold to form the inner layer polyethylene pipe blank; the inner layer polyethylene pipe screw extrusion The machine is integrated with the inner polyethylene pipe mold;

[0028] (3) Vacuum sizing and cooling: quickly spray water vapor to the hole of the inner polyethylene pipe blank, so that the inner wall of the tube hole is rapidly cooled...

Abstract

The invention provides a manufacture process of a steel wire mesh framework composite pipe. A steel wire mesh framework layer is formed by adopting bare steel wires through weaving, the steel wire mesh framework layer and a polyethylene base body material are melted together by using resin in a molten state in a process of producing the composite pipe without causing quality hidden dangers such as spinning, and an inner-layer polyethylene pipe extruding machine and an outer-layer polyethylene pipe extruding machine and a mould are integrated, thus the production efficiency is greatly increased and the production cost is lowered.

Description

technical field [0001] The invention relates to a manufacturing process of a polyethylene pipe, in particular to a manufacturing process of a polyethylene composite pipe with a steel mesh skeleton. Background technique [0002] Plastic pipe is a high-tech composite chemical building material. It is widely used in water supply and drainage and gas pipelines because of its advantages such as small water loss, energy saving, material saving, environmental protection, and convenient completion. Steel mesh skeleton plastic composite pipe is a high-end product among plastic pipes. It uses high-strength copper-plated steel wire to wind and weave reticular structure formed by left and right as the skeleton, and high-density plastic as the matrix material. [0003] At present, the steel wire mesh of the steel mesh skeleton plastic composite pipe is mostly produced with steel wires that have been pre-coated with resin, which requires a separate steel wire lamination production line; i...
