Wear-resistant Mooring Rope
Mooring Ropes:
The ropes used to fasten ships to docks, pontoons, other vessels or for towing are collectively called ship mooring ropes, referred to as mooring ropes, also known as mooring ropes.
As the main component of mooring equipment, there are currently two main types:
fiber rope
wire rope
The most commonly used mooring ropes on ships are chemical fiber ropes.
We mainly use synthetic fibers such as
nylon
polypropylene
polyester, etc.
In addition to light specific gravity, high strength, good impact resistance and abrasion resistance, synthetic fiber cables have the advantages of corrosion resistance, mildew resistance, and insect resistance.
For example
The strength and abrasion resistance of nylon cables are several times higher than those of hemp and cotton cables.
The specific gravity of polypropylene cables is smaller than water and can float on the water, making it easy and safe to operate.

Multiple testing, safe and worry-free
1. Strength test:
Strength test is generally carried out through tensile test. Secure the cable sample to the device and gradually increase the tension until the rope breaks. The tensile strength of the rope is calculated based on the tensile force and the length change before and after breaking.
2. Elongation at break test:
Elongation at break refers to the elongation performance of the rope during the stretching process. Elongation at break testing is usually performed during strength testing, and the elongation at break is calculated based on the change in length before and after breaking.
3. Wear resistance test:
Marine cables are often used in heavy loads and high friction environments, and wear resistance is one of their important properties. The wear resistance test mainly uses the rotational friction method. The rope is wound around a metal cylinder, a certain force and speed are applied, and the wear in the actual environment is simulated through rotational friction. After the test, observe the degree of wear on the surface of the rope and evaluate its wear resistance.
4. Corrosion resistance test:
Marine cables are often exposed to corrosive media such as seawater, acid and alkali solutions in harsh environments such as marine engineering. Corrosion resistance is an important indicator. The corrosion resistance test mainly evaluates the corrosion resistance of the rope by placing it in a corrosive medium for observation.
5. Other test methods:
In addition to the above conventional tests, other tests were also conducted according to the needs of specific application scenarios, such as UV resistance, thermal stability, anti-static performance, melt index, moisture content, etc.
