Description
Technical field
The present invention relates to a kind of wire digging line, particularly a kind of wire digging line with protective coating.
Background technology
Compressor wire drag-line is the stressed member of a kind of key in bridge construction, requires to have higher anti-corrosive durability; Current prestressing force bridge wire digging line is manufactured with reference to standard GB/T/T18365-2001 " cable stayed bridge hot extruded polyethylene high tensile steel wire drag-line technical condition " usually.
The corrosion of compressor wire is the stress corrosion (belonging to couple corrosion category) under stress and corrosion compound action, and be characterized in first forming crackle in metal inside, internal fissure just forms stress after occurring and concentrates, and accelerates the development of crackle, and then produces heavy corrosion.Anticorrosion plating (painting) the layer steel of compressor wire are always on active service under the condition of corrosive medium, by the kind of topping, can be divided into on-metallic protective coating (being called coating), chemical coating and coat of metal (being called coating) three class.1, the nonmetallic coating of nonmetal protective coating prestressing steel mainly contains plastics, epoxy resin and anticorrosion grease three kinds at present; but the anti-aging problem of nonmetallic coating not yet solves; and its mechanical property is much lower compared with the coat of metal, therefore, range of application is restricted.2, chemical coating is by chemical method, forms topping in metal surface, and as the passivation of zinc layers, the oxidation of aluminium lamination, the phosphatization etc. of iron-based, such topping is not often as single steel topping, but annexs with the coat of metal and use.3, metal coating coating is in couple corrosion, and first the metal being in anode is dissolved, and plates with the metal sprinkled compared with ironwork for this reason, as zinc, aluminium etc., in the environment of corrosive medium, making zinc first be protected iron-based by dissolving, being called that anode coating is protected in Steel Wire Surface.Because zinc-plated (or Zn-Al alloy) exists " hydrogen embrittlement " phenomenon, reduce the strength grade of steel wire, always controversial.Therefore compressor wire anticorrosion is the significant problem to closing bridge engineering quality life-span, must strengthen practicable anti-corrosion measure, the massive losses brought to reduce compressor wire to lose efficacy in advance because corrosion causes for prestressing force steel wire.
Polyurea materials reacts by isocyanate component and amino-compound component a kind of elastomer substances generated, and is divided into pure polyureas and half polyureas, and the most basic characteristic of polyureas is exactly anticorrosion, waterproof, wear-resisting etc., is mostly used in space industry at present.

The material of described polyurea protection coating is pure polyureas or half polyurea materials.
Owing to taking above technical scheme, the wire digging line of the band polyurea protection coating of the present invention has following characteristics and beneficial effect:
1. greatly can improve anticorrosion, the damping of wire digging line, cling property, postpone drag-line application life.
The steel wire combination body be made up of the steel wire of band polyurea protection coating due to the band polyurea protection coating wire digging line of the present invention forms, the steel wire of described band polyurea protection coating is made up of single bright steel wire and the protective coating be coated in outside single bright steel wire, protective coating outside the steel wire of this band polyurea protection coating can be the polyurea protection coating being coated in single bright steel wire periphery or the epoxy coating be attached with in the periphery of single bright steel wire, galvanizing coating, plastic coating, anticorrosion grease coating, the surface attachment coating of oiliness wax or the coat of metal or coating and be coated in the compound protective coating that the polyurea protection coating on surface attachment coating or coating formed jointly, because polyurea materials has excellent abrasion resistance, impact resistance and damping property, be coated on the Steel Wire Surface of wire digging line matrix, its coating is continuous, fine and close, can accomplish without seam, free of pinholes, moisture content in isolated air and the infiltration of oxygen, the epoxy coating that steel wire and Steel Wire Surface are attached with can be protected, plastic coating or anticorrosion grease coating not easily aging, the easy loss of galvanizing coating can be slowed down, be subject to the impact of the local defects such as pin hole, greatly improve the antiseptic power of such wire digging line, and increase its anti-wear performance, extend the application life of wire digging line, secondly, the wire digging line of the band polyurea protection coating of the present invention, is also included in wire digging line I b, II b of band polyurea protection coating of I a, II a steel wire combination external Zhou Youyi polyurea protection coating II formation, outer wire digging line I ac, II ac, I bc or II bc being coated with the band polyurea protection coating of polyurea protection coating III of the band that is wrapped that polyurea protection coating III forms is coated with at the be wrapped skin of band of wire digging line I a, II a, I b, II b steel wire combination body, and the wire digging line of above-mentioned various band polyurea protection coating skin or have an individual layer or double-deck HDPE sheath, or be also coated with at the skin of individual layer or double-deck HDPE sheath the wire digging line with the band polyurea protection coating of multiple protective that one deck polyurea protection coating IV forms, because polyurea materials has excellent tensile strength, the characteristic such as ageing-resistant, wear-resistant, the damage caused because constructing operation is improper in the manufacturing and installation process can be reduced, not easily produce cracking, obscission because polyurea coating has, greatly improve the antiseptic power of wire digging line, increase the service life.
2. between compact conformation, steel wire, frictional force is large, strengthens its cling property, and fatigue resistance improves.
All apply in the steel wire outmost surface of the band polyurea protection coating wire digging line of the present invention and gap or be filled with polyurea materials, because polyurea materials has the physical property of high abrasion, therefore, polyurea coating need not be very thick, when they are formed presstressed reinforcing steel, can in regular hexagon or the arrangement of unfilled corner Hexagonal close or the arrangement of other forms between each steel wire, compact conformation, the frictional force of wire digging line can be strengthened, strengthen its cling property; When it applies to cable saddle structure, be more conducive to using under the operating mode of Sarasota both sides by out-of-balance force at drag-line.
3. the present invention can improve the performance of existing coating or coating wire, thus also greatly improves the antiseptic power of wire digging line, and increases its abrasion resistance, extends the application life of wire digging line.
