The high-performance ropes used to lift the Hong Kong-Zhuhai-Macao Bridge are made of ultra-high molecular weight polyethylene fibers that have been successfully developed by YZHX Special Fiber Technology Group in more than ten years.
This ultra-high molecular weight polyethylene fiber is only 1/10 of the thickness of the hair, but after being made into a cable, it is stronger than the steel cable, and each fiber can bear a weight of 35kg. Ultra-high molecular weight polyethylene fiber, carbon fiber, and aramid fiber are called three high-performance fibers. They are the fibers with the highest strength ratio in the world. They are widely used in defense military and civil industries, and are a strategy for strengthening the country and the army. Supplies. The sling used in the Hong Kong-Zhuhai-Macao Bridge is composed of more than 100,000 such wires.
