If we want to know the application of polymer polyethylene, we must first know its properties and advantages, which can make it more widely used and have more powerful applications.
Polyethylene rope is a high-grade fiber, and Dinima, the Netherlands, is a representative at present. Undeniably, the strength of China-made high-molecular polyethylene is still about 10% lower than that of it, but it has an advantage in cost performance and sales volume. Because the strength difference of 10% can be remedied by slightly increasing the diameter. However, domestic polymer R&D companies and institutions are constantly improving, and their strength is always improving, and they will always surpass that of foreign countries. Only competition can make raw material suppliers constantly improve their quality.
The ratio of polyethylene to water is 0.97:1, which can float on the water surface, with an elongation of only 4% and a melting point of 150. It is important to have UV resistance and acid and alkali resistance.
These characteristics can reflect that it can be used in some environments with strong acid and alkali corrosiveness such as sunlight, seawater, etc. More importantly, its strength under the same diameter is more than 6 times that of other common materials, and its weight is also light. If the same strength is required, the diameter of the high-molecular polyethylene rope can be made small, and its weight is several times lighter, so it is easy to operate and suitable for use in important fields such as large ships and warships. For example, nylon is 72mm*220, with a strength of 102 tons and a weight of 702KG. If we need to reach the level of 102 tons, we only need to choose the diameter of 44mm to choose the high-molecular polyethylene, and the weight of 220m is only 215KG. By comparison, we can clearly see the great advantages of polymer polyethylene rope!
Known uses,
First of all, polypropylene filament, polyester, nylon and other materials can be strongly replaced where they are applied, such as mooring lines, towing lines, super-large ship ropes and warships.
Secondly, replace steel wire ropes, such as winch ropes for vehicles, electric traction ropes and nets for mariculture and fishery, which can be used.
After that, I want to highlight his strength, lightness, acid and alkali resistance and anti-aging, so as to make sure that he will occupy a dominant position in these fields in the future.
In the future, the application of polymer polyethylene will occupy a dominant position, and people will definitely not choose ordinary cables with heavy and low strength. With the competition among raw material suppliers, the price of raw materials will inevitably drop, which will be closer to the people, and polymer polyethylene ropes will become mainstream products!
