If we want to know the use of high molecular polyethylene, we must first know its properties and advantages, which can make it more widely used and have more powerful uses.
The high-molecular polyethylene rope is a high-quality fiber. The current Dutch Dyneema is a representative. It is undeniable that the domestic-made high-molecular polyethylene still has a gap of about 10% with it in terms of strength, but in terms of cost performance, And the advantage in sales, because a 10% difference in strength can be remedied by a slight increase in diameter. However, domestic polymer research and development companies and institutions are constantly improving, and the strength has been improving, and there will always be more than foreign countries. Only competition will enable raw material suppliers to continuously improve their quality.
The proportion of high molecular polyethylene and water is 0.97:1, it can float on the water surface, the elongation is only 4%, the melting point: 150, and it is important to have UV resistance, 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 and seawater. More importantly, its strength is more than 6 times that of other ordinary materials under the same diameter, and its weight is also light. If Under the same strength requirements, the high-molecular polyethylene rope can be made smaller in diameter and several times lighter in weight, which is easy to operate and suitable for important fields such as large ships and warships. For example, nylon is 72mm*220 meters, the strength is 102 tons, and the weight is 702KG. If we need to reach the level of 102 tons, we only need to choose a diameter of 44mm for high molecular polyethylene, and the weight of 220 meters is only 215KG. By comparison, we can clearly see the great advantages of high molecular polyethylene rope!
currently known uses,
First of all, polypropylene filament, polyester, and nylon can be strongly replaced wherever they are applied, such as mooring cables, towing cables, ropes for super-large ships, and warships.
Secondly, replace the steel wire rope, such as winch rope for vehicles, electric traction rope, net for marine aquaculture and fishery, all can be used.
After that, I want to highlight his high strength, lightness, acid and alkali resistance, and anti-aging, to determine that he will occupy a dominant position in these fields in the future.
In the future, the application of high-molecular polyethylene will dominate. People will definitely not choose heavy and low-strength ordinary cables. With the competition among raw material suppliers, the price of raw materials will inevitably drop, and it will be more close to the people. Vinyl rope will become a mainstream product!
