Jiangsu Zhongwang Cable Composite New Materials Co., Ltd. has a Zhongwang Cable New Materials Research Institute. Designed and managed by a team led by the main research unit of the National Science and Technology Progress Award and the professional college; We have invested heavily in the research and industrialization of deep-sea high-performance aquaculture, fishing, sports, military, nuclear power, and other medium and heavy-duty (400D>100 shares) twisted/woven knotless nets; To become the largest and technologically leading twisting/weaving net research and development, production, and sales factory in China. Through years of technological research and development, we have broken through the conventional width of 100 mesh for twisted/woven mesh without knots, and become the only medium and heavy-duty mesh in China with a width of 200 mesh. This can significantly reduce the amount of mesh splicing and connection deformation, and improve the safety of mesh equipment in long-term service. According to the safety requirements of different occasions such as fishing with twisted/woven nets, we have successfully developed and produced internationally leading products for medium and heavy-duty three strand twisted/woven nets. United Aquaculture Group has successfully applied and tested large-scale deep-sea aquaculture cages for many years; The long-term service performance of wind and wave resistance, water exchange level, cyclic loading fatigue performance, creep, etc. has reached the international leading level. Using HDPE and other polymer alloy materials for single strand twisting/weaving to manufacture deep sea net cages, the average weight of the net is reduced by 50% compared to those with knots 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; There is also an innovative resin coating protection technology that improves the anti algae fouling, wear resistance, and aging longevity performance of the net cage.
