Feasibility report research: analysis of the development prospects and status quo of the poly V-belt industry in 2022

The cast polyurethane V-belt is a V-belt made of polyester cord as the belt core and cast and vulcanized with polynitrophenol rubber. Its manufacturing methods include atmospheric pressure casting, casting molding and centrifugal casting. This kind of tape has the characteristics of high hardness, good elasticity, excellent wear resistance, high mechanical strength, large friction coefficient, high transmission power and thin belt body, stable operation, radiation resistance and other characteristics. V-belts with internal and external teeth and V-belts with internal and external teeth are widely used in high-speed power transmission of various machines.

The domestic V-belt tensile body was first made of cotton cord fabric, and in the 1970s, most manufacturers switched to rayon. Next, vinyl cord fabric was used, and some special V-belts used glass fiber and steel wire as the tensile body. With the development of my country's machinery industry, The tensile body material of the V-belt can no longer meet its requirements, and there is a certain gap compared with the international advanced level. For this reason, the Rubber Division of the Ministry of Chemical Industry requires the polyester of the V-belt skeleton material in the "Eighth Five-Year Plan" plan, which is widely accepted by the international market. level.

With the implementation of the regional development strategy, my country's regional economic aggregates continue to rise, the economic structure continues to be optimized, and the overall regional development gap is narrowing. In the practice of promoting the supply-side structural reform, the state has played an active role in the overall development of the western region, the revitalization of the northeast, the rise of the central region, and the development of the eastern region, based on leveraging the comparative advantages of various regions and narrowing the regional development gap.

It can be seen from the data that the proportion of legal entities in the eastern region has decreased slightly, and that of legal entities in the central and western regions has increased slightly. Behind the exploration of this phenomenon is the implementation of the national regional development strategy and the intuitive embodiment of promoting regional development coordination. It is also the enhancement of the attractiveness of various elements in the central and western regions, which provides a guide for the future development of local urban industrial clusters.
