Performance and maintenance of high molecular polyethylene cable

Main properties of high molecular polyethylene rope: 

Passed the 640kv/5min power frequency withstand voltage test (electricity). It is light in weight and floats on the water surface, which is about 87.5% lighter than a steel cable of the same diameter. The highest strength in the world, about 1.5 times higher than the strength of the steel wire rope of the same diameter. Different durability, seawater resistance, chemical resistance, UV radiation and repeated temperature differences, the quality of use is unchanged. The operator is convenient, fast, and safe to use, and the operation is short, such as the army's ability to maneuver quickly in certain situations.

Types and maintenance methods of polymer polyethylene ropes:

Ropes are still relatively common in life, but many people are not very clear about some small uses of ropes. There are actually many types of ropes, which are distinguished according to their uses:

1. Static rope, also known as white rope, is used for rappelling cave exploration. Although the elasticity is ultra-low, it has strong wear resistance.

2. Power ropes are also called flower ropes and braided ropes. They are used as a necessary item for sports climbing or pioneer climbing. They have high-quality elasticity, but are expensive. ).

3. The power rope (with waterproof treatment) is mainly used for water sports such as river tracing and ice climbing due to its special waterproof treatment, with a diameter of about 10mm-11mm.

4. Marine ropes, used for boat mooring. In addition to light specific gravity, high strength, and good impact resistance and wear resistance for ship ropes, nylon ropes have the advantages of corrosion resistance, mildew resistance, and insect resistance. For example, the strength and wear fastness of nylon cables are several times higher than those of hemp and cotton cables. According to the processing structure, chemical fiber cables are divided into two types: 3-strand, multi-strand twisted cables and 8-strand, multi-strand twisted cables. The diameter of 3-strand cables is generally 4 to 50 mm, and the diameter of 8-strand cables is generally 35 to 120 mm. In addition to being used for ship moorings, chemical fiber cables are also widely used in square rope nets such as transportation, industry, mining, sports and fishing.

Due to the inconvenient storage of the rope, it is not a popular rope appliance; the rope avoids the wrong use methods such as sunlight, acid solution (non-neutral detergent), abuse (bringing SM or stepping on the rope), etc. In the laundry bag, throw it into the washing machine, put in neutral detergent, wash it, and then dry in the shade. When collecting the rope, carefully verify the skin and twist of the rope. If the skin is broken or sprayed, cut it and use it for other purposes. When cutting the rope, stick the tape to both ends of the cutting point, and then fuse the rope end with fire after cutting.
