Xuzhou Zhongwang Cable New Materials Research Institute is composed of the main research unit of the National Science and Technology Progress Award, the East China Sea Institute of the Chinese Academy of Fishery Sciences, Donghua University and other professional institutes; United Aquaculture Group has successfully applied and tested large-scale deep-sea aquaculture cages for many years; The long-term service performance such as wind and wave resistance, flow resistance, water exchange level, cyclic loading fatigue performance, creep, etc. has reached the international leading level. Manufacturing deep sea net cages using HDPE and other polymer alloy materials with single strand twisting/weaving, resulting in an average weight reduction of 50% compared to netting or warp knitting; After the frontal impact test of a 15 level typhoon, there was no damage. Ultra high molecular weight polyethylene with internationally leading levels of fatigue resistance, twisted/woven without knots, has an average weight reduction of 100% compared to warp knitting or with knots; Research on innovative resin coating protection technology has improved the anti algae fouling, wear resistance, and aging longevity performance of net cages.
