Embodiment 1

[0032] The technical solution of the present invention is as follows: a novel steel mesh plastic composite pipe processing technology, including the following steps.

[0033] 1. Make use of the wire distribution rack to evenly distribute the multiple steel wires 4 in 360°.

[0034] 2. Coat the surface of each steel wire 4 with a layer of hot melt adhesive 3 by using a plastic extruder and a plastic-coating mold.

[0035] 3. Use a tractor to bring the steel wire 4 coated with the hot melt adhesive 3 into the extrusion die of the inner plastic layer 2 and distribute it evenly.

[0036] 4. Use a plastic extruder to extrude plastic into the mold of the inner plastic layer 2 to cover the steel wire 4, and form a ring-shaped inner plastic layer 2. While forming the inner plastic layer 2, use another plastic extruder The machine extrudes one deck of hot melt adhesive 2 6 and is coated on the outer wall of the inner plastic layer 2 .

[0037] 5. Use a cooling water tank for plastic ...

Embodiment 2

[0044] Before step one, the outer surfaces of the steel wires 4 and the steel wires of the steel mesh layer 5 are embossed with patterns. Other schemes are the same as in Embodiment 1.

Embodiment 3

[0046] In step 2, the steel wires 4 pass through the steel wire plastic-coating mold, and at the same time, all the steel wires are coated with hot melt adhesive 1-3. Other schemes are the same as in Embodiment 1.

Abstract

The invention relates to a plastic pipe processing technology, in particular to a novel steel net and plastic composite pipe processing technology. The novel steel net and plastic composite pipe processing technology comprises the steps of wire dividing, rubber coating, extrusion of an inner plastic layer, extrusion of hot melt adhesive, winding of a steel wire net layer, extrusion of a hot melt adhesive layer, extrusion of an outer plastic layer and the like. Due to the fact that the axial steel wire structure and the circumferential-direction steel wire net structure are adopted at the same time, the rigidity strength of a pipe is improved, and the pipe is not prone to bent deformation and more applicable to the using condition of aerial installation.

Description

technical field [0001] The invention relates to a plastic pipe processing technology, in particular to a novel steel mesh plastic composite pipe processing technology. Background technique [0002] Steel-plastic composite pressure pipes are widely used in municipal buried water supply, building buried water supply, buried fire water supply, industrial sewage discharge (pressure pipe), industrial acid-base solution and powder or slurry transportation. There are two types of composite pipes in the domestic market: steel skeleton polyethylene plastic composite pipe and steel mesh skeleton plastic composite pipe. [0003] The existing steel skeleton plastic polyethylene composite pipe (the structure is as described in the patent No. CN98119383.8, named "Reticular Steel Skeleton - Manufacturing Method and Device of Reticular Steel Skeleton of Plastic Composite Pipe" Chinese Invention Patent) during the production process , it is usually necessary to make the steel wire into a me...
