Nebike Sports. The sports wooden floor of the gymnasium has three characteristics: sports function, protection function and technical performance, and the effect evaluation and related indicators of the floor structure composed of wooden surface board, wooden keel and elastic pad, etc. Test methods are specified in detail.
1. Sports functionality means that the floor can ensure that all technical indicators of sports can achieve the best performance. Motor function is often evaluated by ball rebound rate, standard vertical deformation, and relative vertical deformation rate.
2. The protection function is usually measured by impact absorption rate, standard vertical deformation and relative vertical deformation rate. The shock absorption rate refers to the change of the rebound force of the detected surface relative to the rebound force of a solid ground (concrete ground). Sports wood flooring requires that the impact absorption rate should be greater than or equal to 53% to ensure that athletes will not be injured during exercise. When the wood material is directly used as the floor material, due to its good elasticity and plasticity, it can ensure the movement function and the protection function at the same time under the structural conditions of the appropriate keel and elastic pad.

3. The explanation of the technical performance in the sports floor is the performance of the sports wooden floor that can carry and use sports equipment or non-sports equipment on it under the premise of maintaining the sports function and protection function for a long time. In other words, it means that the load-bearing load and firming service life of the floor must meet the requirements of competition and training. PVC sports floor is a kind of sports floor specially developed for sports venues using polyvinyl chloride materials. Specifically, it uses polyvinyl chloride and its copolymer resin as the main raw material, and adds fillers, plasticizers, stabilizers, colorants and other auxiliary materials. , on a sheet-like continuous substrate, produced by a coating process or by a calendering, extrusion or extrusion process. Generally, it is formed by stacking a multi-layer structure, generally including a wear-resistant layer (including UV treatment), a glass fiber layer, an elastic foam layer, and a base layer. PVC sports flooring is widely used, and various international competitions such as the Olympic Games specify the use of PVC sports flooring. It can be seen that the market prospect of this PVC sports flooring is very broad.
