1. The main performance of high molecular polyethylene cable: Passed 640kv/5min power frequency withstand voltage test (electric power). Light weight, floating on the water, about 87.5% lighter than steel wire ropes of the same diameter. The highest strength in the world, about 1.5 times stronger than steel wire ropes of the same diameter. Different durability, sea water resistance, chemical resistance, ultraviolet radiation and temperature difference repeated, the quality of use remains unchanged. The operation of the stone throwing net is convenient, fast, safe to use, and the operation is short, such as the ability of the army to move quickly under certain circumstances. 2. Types and maintenance methods of high molecular polyethylene ropes: Ropes are still relatively common in life, but many people are not very clear about the small uses of ropes. There are actually many types of ropes, which are distinguished by purpose: 1. Static rope, also known as white rope, is used for rappelling cave exploration. Although it has ultra-low elasticity, it has strong abrasion resistance. 2. Power ropes are also called flower ropes and braided ropes. They are used as necessary items for sports climbing or pioneer climbing. They have high-quality elasticity, but they are expensive. Generally, the diameter is 10mm-11mm (9mm is optional for mountaineering. ). 3. Power rope (with waterproof treatment) is mainly used for water-based sports such as river tracing and ice climbing due to its special waterproof treatment. The diameter is about 10mm-11mm. 4. Marine ropes, used for mooring boats. In addition to light specific gravity, high strength, good impact resistance and abrasion resistance, the ship rope has the advantages of corrosion resistance, mildew resistance, and insect resistance. For example, the strength and abrasion fastness of nylon cables are several times higher than that of hemp and cotton cables. The specific gravity of polypropylene cables is less than water and can float on the water surface, which is convenient and safe to operate. According to the processing structure, chemical fiber ropes are divided into two types: 3-strand and multi-strand twisted rope and 8-strand and multi-strand braided twisted rope. The 3-strand rope generally has a diameter of 4-50 mm, and the 8-strand rope generally has a diameter of 35-120 mm. In addition to being used for ship mooring, chemical fiber ropes are also widely used for square rope nets in transportation, industry, mining, sports and fishery. Because the storage of the rope is inconvenient, it is not a popular rope appliance; the rope should be used to avoid incorrect use methods such as sunlight, acid solution (non-neutral detergent), abuse (using SM or stepping on the rope), etc., generally put the rope In the laundry bag, throw it into the washing machine, put in a neutral detergent, wash it, and then dry it in the shade. When storing the rope, you must carefully verify the skin and twist of the rope. If the skin is broken or sprayed, cut and use it for other purposes. When cutting the rope, stick the tape to the ends of the cutting point. After cutting, use fire to fuse the ends of the rope. Shengrui.
