It can be used in the fields of advanced construction, vehicle bundle, traction and strapping, for shipping, marine oil exploration, aircraft maneuvering and marine fishing, trawl, fixing nets, coil nets and other fishery aspects.
The rope core of galvanized steel wire rope formerly used in sisal and jute manufacture, but because these materials are easy to absorb acid, alkali, seawater and other corrosive substances at work, resulting in the early corrosion of the inner layer steel wire broken wire, has been converted to polypropylene as the core.
The twist of galvanized steel wire rope is the same as that of ordinary round strand wire rope, but according to the working conditions of wire rope, there are different requirements for the thickness of zinc layer of raw steel wire: diameter 0. $number. 0mm Farragut and I galvanized steel wire rope, the thickness of the coating can be divided into 3 groups: The thin coating group of zinc on the 15~135g/m2, used for mild corrosion conditions; The zinc content in the middle coating group was 60~200g/m2, which was used for medium corrosion condition, and the zinc content in the thick galvanizing group was 75~260g/m2 For severe corrosion conditions. In order to ensure the quality of steel wire rope, the surface of galvanized layer should be smooth, complete, uniform and firm. When galvanized steel wire is spirally wound in diameter of steel wire diameter of 5 times times or 10 times times the core bar, the zinc layer should not fall off or crack. The corrosion resistance of galvanized layer should be tested accordingly.
