Embodiment 1

[0171] A method for manufacturing a steel wire cable with a polyurea protective coating, which is to firstly produce a steel wire with a polyurea protective coating, and then pass the steel wire with a polyurea protective coating through a polyurea material filling process through wire separation, and then fill the steel wire with a polyurea protective coating. Each steel wire with polyurea protective coating is filled with polyurea material 32, and then undergoes agglomeration step to form a steel wire assembly composed of n steel wires with polyurea protective coating, forming a steel wire with polyurea protective coating Steel wire cables Iae and IIae with polyurea protective coating composed of and filled with polyurea material 32 between the steel wires with polyurea protective coating;

[0172] Its specific steps include: A, making steel wire with polyurea protective coating; B, splitting C, polyurea material filling process: filling polyurea material 32 between the steel...

Embodiment 2

[0203] Steel wires with polyurea protective coating are filled with polyurea materials between the steel wires with polyurea protective coating inside the steel wire assembly. There is a polyurea protective coating II on the periphery of the steel wire assembly with polyurea protective coating. The production method of steel wire cable with protective coating:

[0204] A steel wire assembly made of n steel wires with a polyurea protective coating made in Example 1, and a steel wire assembly with a polyurea protective coating filled with polyurea material between each steel wire with a polyurea protective coating Steel cables Iae and IIae go through E: polyurea material coating process II, that is, through one of the following methods:

[0205] ① Extrusion coating: polyurea material hot-extruded by steel wire cable Ⅰae or Ⅱae through extrusion equipment;

[0206] ② Spraying: heat and pressurize the equipment, the raw materials are mixed at the nozzle, and then the polyurea mat...

Embodiment 3

[0225]The steel wire assembly of the steel wire cable with a polyurea protective coating has a wrapping tape outside the body, and the outer layer of the wrapping tape is coated with a polyurea protective coating. The production of a steel wire cable with a polyurea protective coating method:

[0226] The steel wire cables Iae and IIae with a polyurea protective coating produced in Example 1 and the steel wire cables Ibe and IIbe with a polyurea protective coating produced in Example 2 were subjected to F: wrapping forming step, wrapped The upper wrapping tape 5 constitutes a steel wire cable Iaeo, IIaeo, Ibeo or IIbeo with a polyurea protective coating (see Figure 4-1 to Figure 4-4 ).

[0227] Then wrap the steel wire assembly with a polyurea protective coating steel wire cable Ⅰaeo, Ⅱaeo, Ⅰbeo or Ⅱbeo with a wrapping tape, and then go through G: polyurea material coating process III, that is, through one of the following methods:

[0228] ①Extrusion coating: the polyurea ...

Abstract

The invention relates to a manufacturing method for a steel wire inhaul cable with a polyurea protective coating. The manufacturing method includes the steps that steel wires with polyurea protective coatings are manufactured, the steel wires with the polyurea protective coatings pass through the polyurea material filling process through wire dividing, after the positions between the steel wires with the polyurea protective coatings are filled with polyurea materials, a steel wire combination with the polyurea protective coating is formed through the step of coalescence, the positions between the steel wires, with the polyurea protective coatings, of the steel wire combination are filled with the polyurea materials to form steel wire inhaul cable bodies Iae and IIae with the polyurea protective coatings; the steel wire inhaul cable bodies which are of two structures and are provided with the polyurea protective coatings serve as basic structures, and the steel wire inhaul cable which has multiple protection layers and is provided with the polyurea protective coating is formed through one or more of the wrapping and packaging molding process, the PE sleeve extrusion molding processes I and II and polyurea material coating processes II, III, IV and the like. The manufacturing method is economical and practical, and the manufactured steel wire inhaul cable with the polyurea protective coating is compact in structure and antiseptic, reduces shocks, and is good in skid resistance and abrasive resistance.

Description

technical field [0001] The invention relates to a manufacturing method of a steel wire cable, in particular to a manufacturing method of a steel wire cable with a protective coating. Background technique [0002] The prestressed steel wire cable is a key stress-bearing part in the bridge structure, which requires high corrosion resistance and durability; at present, the bridge steel wire cable used for prestressing usually refers to the national standard GB / T18365-2001 "Hot extrusion of cable-stayed bridges". Ethylene high-strength steel wire cable technical conditions" for production and manufacturing. [0003] The corrosion of prestressed steel wire is stress corrosion under the combined action of stress and corrosion (belonging to the category of galvanic corrosion). corrosion. The anti-corrosion plated (coated) steel of prestressed steel wire is always served under the condition of corrosive medium. According to the type of protective layer, it can be divided into non-...
