Embodiment 1

[0142]A method for manufacturing a steel wire cable with a polyurea protective coating, which comprises the steps of dividing and merging the steel wires with the polyurea protective coating to form a steel wire composed of n steel wires with the polyurea protective coating The combination, thereby forming a steel wire cable Ia with a polyurea protective coating or a steel wire cable IIa with a polyurea protective coating;

[0143] The specific steps include:

[0144] A. Making a steel wire with a polyurea protective coating: make a steel wire 41 with a polyurea protective coating consisting of a single smooth steel wire 1 and a polyurea protective coating I31a coated on the outer periphery of the single smooth steel wire 1 or It is a steel wire 42 with a polyurea protective coating with a composite protective coating composed of a single smooth steel wire 1 and a composite protective coating outside the single smooth steel wire;

[0145] B. Wire splitting: Pull the steel wir...

Embodiment 2

[0170] The production method of a steel wire cable with a polyurea protective coating consisting of a polyurea protective coating II on the periphery of a steel wire assembly composed of a steel wire with a polyurea protective coating:

[0171] The steel wire assembly composed of n steel wires constitutes a steel wire cable Ia with a polyurea protective coating or a steel wire cable IIa with a polyurea protective coating and then passes through D: Polyurea material coating process II, that is: through the following One of the ways:

[0172] ①Extrusion coating: Polyurea material hot-extruded by wire cable Ia or IIa through extrusion equipment;

[0173] ②Spraying: The equipment is heated and pressurized, the raw materials are mixed at the nozzle, and the polyurea material is sprayed onto the steel wire cable Ia or IIa by the spray gun;

[0174] ③Immersion and painting: The steel wire cable Ia or IIa is soaked in the polyurea coating through the traction equipment, and is formed...

Embodiment 3

[0192] The steel wire assembly of the steel wire cable with polyurea protective coating has a wrapping tape outside the body, and the outer layer of the wrapping tape is coated with a layer of polyurea protective coating. The production method of the steel wire cable with polyurea protective coating:

[0193] The steel wire cables Ib or IIb with polyurea protective coating produced in Example 2 go through the F: wrapping forming step, and wrap a wrapping tape 5 to form steel wire cables Ibo and IIbo with polyurea protective coating ( see Figure 4-1 ~ Figure 4-2 ).

[0194] Then the steel wire assembly is wrapped with a wrapping tape with polyurea protective coating steel wire cables Ibo and IIbo, and then go through G: polyurea material coating process III, that is, through one of the following methods:

[0195] ① Extrusion coating: the polyurea material that is hot-extruded from steel wire cables Ⅰb or Ⅱb with polyurea protective coating through extrusion equipment;

Abstract

The invention relates to a manufacturing method for a steel wire inhaul cable with polyurea protective coatings. The manufacturing method includes the steps that after steel wires are pretreated and dried, the single bright steel wire or a coating or clad layer attached to the single bright steel wire is coated with a polyurea material in manners of extrusion coating, spraying, soaking extraction coating and machine brushing, and the steel wires with the polyurea protective coatings are formed; a steel wire combination composed of the steel wires with the polyurea protective coatings is formed by the steel wires with the polyurea protective coatings through the steps of coiling, wire dividing and coalescence, and the steel wire inhaul cable Ia or IIa with the polyurea protective coatings is accordingly formed; on the basis of the steel wire inhaul cable of the two structures, the steel wire inhaul cable which has multiple protection layers and is provided with the polyurea protective coatings is formed through one or more of the wrapping and packaging molding working procedure, PE sleeve extrusion molding working procedures I and II, polyurea material coating working procedures II, III, IV and the like. The steel wire inhaul cable which is manufactured with the method and provided with the polyurea protective coatings 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-...
