Professional and technical characteristics of PVC table tennis floor

1. Comfort issues:

The surface of the professional PVC plastic sports floor can be moderately deformed when it is impacted, just like a sealed mattress with air inside. When you fall or slip, the cushioning effect provided by the closed foam back layer technology can maximize the impact. Reduce sports injuries.

2. The problem of tremor:

Tremor refers to the range of the floor that is deformed by impact. The larger the range of tremor, the easier it is to cause fractures. There are two types of tremors: point tremors and regional tremors.

3. The problem of vibration absorption:

The impulse formed by people during exercise will cause vibration on the surface of the PVC table tennis flooring. The structure of the floor must have the function of shock absorption, which means that the floor should have the performance of absorbing impact energy. The impact force is much smaller than the movement on hard ground, such as on concrete ground. That is, when the athlete jumps up and falls back to the floor, at least 53% of the impact should be absorbed by the floor, so as to protect the athlete's ankle joint, meniscus, spinal cord, and brain, so that people will not be affected during exercise. harm. Its protective function also considers that a person cannot affect adjacent persons when moving on the PVC plastic sports floor. This is the concept of shock absorption, shock deformation and extension deformation described in the German DIN standard.

4. The problem of friction coefficient:

Research has shown that 12% of basketball player injuries occur while spinning in place. The coefficient of friction of a sports floor indicates whether the floor is too frictional (which reduces flexibility in turning) or too slippery (which increases the risk of slipping). Considering the athlete's mobility and safety, the friction coefficient between 0.4-0.7 should be the optimal value. The friction coefficient of the PVC plastic sports floor is generally maintained between this coefficient. The friction coefficient of the professional PVC plastic sports floor is 0.57. It has sufficient and moderate friction, which can ensure the stability of movement and can move in all directions. To maintain the consistency and regularity of friction performance, to ensure flexible movement and in-situ rotation without any hindrance.

5. The problem of ball resilience:

The ball rebound test is to drop the basketball from a height of 6.6 feet to the sports floor to test the rebound height of the basketball. This data is expressed as a percentage, and the rebound height of the basketball on the concrete floor is used as the comparison standard to reflect the difference in rebound height. The rules of indoor ball games require the use of the ground for sports competitions or training, such as the take-off action of basketball and other ball sports and the rebound of the sphere. PVC plastic sports floor has excellent and stable ball rebound performance, there is no elastic dead center on the floor, and its rebound comparison coefficient can reach up to 98%.

6. The problem of sports energy return:

This refers to the sports energy returned by the PVC plastic sports floor when the athlete is exercising to improve the sports performance.

7. Problems with rolling loads:

The load-bearing load, firmness and service life of professional sports floors must meet the requirements of competition and training. For example, when movable basketball racks and related sports facilities are moved on the floor, the surface and structure of the floor must not be damaged. This is the German DIN standard. Rolling load criteria and concepts described.
