Embodiment 1

[0032] A new type of high-strength synthetic fiber rope, including strands and a covering body 6 wrapped around the strands. The strands include a central strand 1, and the periphery of the central strand is provided with a first strand layer composed of six first strands 2. The first strands 2 are all tangent to the central strand 1 and adjacent to the second strand. One strand 2 is in tangential contact, and the periphery of the first strand layer is provided with a second strand layer consisting of six second strands 3 and six third strands 4, and the second strand 3 is connected to the third strand. The strands 4 are arranged in a staggered manner, and the adjacent second strands 3 and the third strands 4 are in tangential contact, the second strands 3 and the third strands 4 are both tangent to the first strands 2, and the second strands 3. Different from the diameter of the third strand 4, the outer periphery of the second strand layer is provided with an outer strand la...

Embodiment 2

[0038] The difference from Example 1 is that the material used for the strands is a mixture of carbon fiber, aramid fiber and PBO fiber. The fibers of the strands are treated with a repairing agent, the microscopic defects of the fibers are repaired, dried and solidified, and then shaped and twisted to form strands.

[0039] The repairing method is as follows: the repairing agent is driven by pressurized nitrogen to form an aerosol, and is sprayed into the pulled synthetic fiber rope in the form of aerosol at a temperature of 60°C to 80°C, and the pulling speed of the synthetic fiber is 10 meters / second, and then continue to pull and cure through multi-stage heating. The multi-stage heating curing is specifically: the temperature of the first stage is 80°C-100°C, the temperature of the second stage is 100°C-120°C, and the temperature of the third stage is 120°C-160°C.

[0040] The restoration agent is carborane polyester and CeO 2A mixture of which CeO 2 The weight ratio ...

Embodiment 3

[0043] The difference from Example 1 is that the materials used for the strands are carbon fiber and aramid fiber. The fiber strands of the strands are treated with a repairing agent to repair the microscopic defects of the strands, then dry and solidify, and then are reshaped and twisted to form strands.

[0044] The repairing method is as follows: the repairing agent is driven by pressurized nitrogen to form an aerosol, and is sprayed into the pulled synthetic fiber rope in the form of aerosol at a temperature of 60°C to 80°C, and the pulling speed of the synthetic fiber is 5 meters / second, and then continue to pull and cure through multi-stage temperature rise. The multi-stage heating curing is specifically: the temperature of the first stage is 80°C-100°C, the temperature of the second stage is 100°C-120°C, and the temperature of the third stage is 120°C-160°C.

Abstract

The invention relates to a method for repairing defects in the microstructure of synthetic fibers, a high-strength synthetic fiber rope, and a method for repairing the microstructure of synthetic fiber ropes. The temperature condition is sprayed into the pulled synthetic fiber rope, and the synthetic fiber rope is pulled at a speed of 0.1 to 10 m / s, and then cured by multi-stage heating; it is characterized in that: the repair agent is composed of carborane polyester and carbon dioxide Cerium is mixed, and the weight ratio of cerium dioxide in the restoration agent is 0.1-0.5%. The strands of the high-strength synthetic fiber rope are processed by the aforementioned treatment methods. The advantage lies in that the internal microstructure of the synthetic fiber rope can be significantly improved, and the strength performance is greatly improved.

Description

technical field [0001] The invention relates to a method for repairing fibers and a fiber rope, in particular to a method for repairing defects in the microstructure of synthetic fibers and a high-strength synthetic fiber rope. Background technique [0002] The ultimate tensile strength of the steel wire rope is only 1670MPa, and the tensile strength of the existing synthetic fiber rope is equivalent to that of the steel wire rope, and the tensile strength is insufficient in environments such as hoisting and strong impact. The ropes used in marine engineering machinery are in a high-salt corrosion environment, and the steel wire ropes are extremely susceptible to corrosion and shorten their service life, so they are frequently replaced. Due to the heavy dust in coal mines and other environments, the steel wire ropes used for friction lifting in mines need to be lubricated with lubricating oil, which makes them easily stained with dust, forming blockages, increasing the frict...
