1.？ Comfort issues:

Enyoo professional PVC? When the plastic sports floor is hit, its surface can be moderately deformed, just like a sealed mattress with air inside. When you fall or slip, the cushioning effect provided by closed foam backing technology can minimize sports injuries.

2.？ The question of tremor:

Tremor refers to the range of floor deformation caused by impact. The larger the tremor range, the easier it is to cause fractures. There are two kinds of tremors: point tremors and area tremors.

3.？ Problems of vibration absorption:

What is the influence of the impulse formed in the process of exercise? PVC？ Plastic sports floor will produce vibration on the surface, and the floor structure must have vibration absorption function, that is to say, the floor should have the performance of absorbing impact energy. PVC？ The impact resistance of plastic raised floor is much smaller than that of hard floor, such as cement floor. That is, athletes jump up and fall back? PVC？ At least the floor? 53? What is the impact of more than%? PVC？ Absorbed by the floor, it plays a role in protecting athletes' ankles, meniscus, spinal cord and brain, so that people will not be hurt during sports. Its protection function also takes into account a person's presence? PVC？ When the plastic sports floor moves, it shall not affect the adjacent people. This is Germany? DIN？ The concepts of vibration absorption, vibration deformation and extension deformation described in the standard.

4.？ The problem of friction coefficient:

Research shows that? 12? % of basketball players were injured in the process of in-situ rotation. The friction coefficient of the moving floor indicates whether the floor is too friction (which will reduce the flexibility of rotation) or too slippery (which will increase the risk of slipping). Considering the athlete's activity ability and safety, what is the friction coefficient? 0.4-0.7? Between should be the best value. Enyoo professional PVC? The friction coefficient of plastic sports floor is 0.57, and the friction force is sufficient and moderate, which can ensure the stability of sports, and at the same time maintain the consistency and regularity of friction performance in all directions of sports, and ensure that flexible movement and in-situ rotation are not hindered.

5.？ The elasticity of the ball;

The test of ball elasticity is to take basketball from? 6.6? Feet? The height of the ball falling on the sports floor is used to test the rebound height of basketball. This data is expressed as a percentage, taking the rebound height of basketball on the concrete floor as a comparison standard, reflecting the difference in rebound height. According to the rules of indoor ball games, it is required to use the ground for sports competition or training, such as the take-off action and ball rebound of ball games such as basketball. The rebound comparison coefficient of ground balls in the competition venue should be greater than or equal to? 90? %。 Major? Enyoo professional PVC? Plastic sports floor has outstanding and stable ball rebound performance, and the floor has no elastic dead point, and its rebound comparison coefficient can reach the highest? 98? %。

6.？ Motion energy regression problem;

What does this mean? PVC？ The sports energy returned by the plastic sports floor can improve the sports efficiency.

7.？ The problem of rolling load:

The bearing, consolidation and service life of professional sports floor must meet the requirements of competition and training. For example, when the movable basketball stand and related sports facilities move on the floor, the surface layer and structure of the floor will not be damaged. This is Germany? DIN？ Rolling load standards and concepts described in the standard.

Second,? PVC？ Comparison between sports floor and solid wood sports floor

1.？ PVC？ Sports floor has a wider range of applications:

PVC？ Sports floor is the best choice for all ball sports venues, including basketball, in international official competitions. Generally, internationally recognized badminton, table tennis, volleyball, handball and other sports venues are adopted? PVC？ Sports floor. Compared with solid wood sports floor, PVC? The sports floor has better safety, shock absorption and resilience. The application scope of solid wood sports floor is relatively narrow.

In addition, the installation of solid wood sports floor is more complicated, and it can not meet the needs of customers to do mobile venues. And then what? PVC？ The sports floor is easy to install, and the movable sports floor can also meet the special needs of customers as a mobile venue.

2.？ PVC？ The sports performance of the sports floor is excellent:

PVC？ Compared with solid wood sports floor, sports floor has superior sports performance, which is mainly reflected in the following aspects:

. ? comfortable

Generally speaking, the comfort of sports floor is:? PVC？ Plastic sports floor-acrylic (polyurethane) sports floor-rubber floor-solid wood sports floor.

. ? Tremor-point tremor and area tremor

Regional tremor refers to the range of floor deformation caused by impact. The greater the tremor, the easier it is to cause fractures. The tremor of solid wood sports floor is a typical regional tremor. ? PVC？ Because of the closed honeycomb structure, the sports floor has a small tremor range and belongs to point tremor, which protects the athlete's body to the maximum extent.
