Several technical issues related to pvc multi-layer composite sports flooring comfort issues:
The surface of the professional pvc sports floor can be moderately deformed when impacted, like a mattress with air inside. When you are wrestling or slipping, the cushioning effect provided by the closed foam back layer technology can minimize the damage. .
Tremor problem:
Tremor is the extent to which the floor is deformed by impact. The larger the tremor area, the more likely it is to cause a fracture. There are two kinds of tremors: point tremors and regional tremors.
Vibration absorption problem:
The impulse that people form during exercise will produce vibration on the surface of pvc sports floor. The structure of the floor must have the function of shock absorption, which means that the floor should have the ability to absorb impact energy. The athletes are affected by the pvc sports floor. The impact force is much smaller than on a hard surface such as a concrete floor. In other words, when an athlete jumps up and down to the pvc floor, at least 53% of the impact must be absorbed by the pvc floor, thereby protecting the athlete's ankle, meniscus, spinal cord, and brain. Will not be hurt. Its protection function also considers that a person cannot influence neighboring people when pvc flooring is exercised. This is the concept of shock absorption, vibration deformation and extension deformation described in the German DIN standard.
The friction coefficient problem:
Studies have shown that 12% of basketball player injuries occur during the rotation of the place. The coefficient of friction of the sports floor indicates whether the floor is too strong (this will reduce the flexibility of rotation) or too slippery (this will increase the risk of slipping). Taking into account the athlete's ability to move and safety, the friction coefficient should be the best value between 0.4-0.7. The coefficient of friction of the professional pvc flooring is generally maintained between this coefficient, it has sufficient and moderate friction, can guarantee the stability of the movement, and can maintain the consistency and regularity of friction performance in each moving direction. Guaranteed flexible movement and rotation in place without any obstacles.
Ball rebound problem:
The resilience test is to drop the basketball from a height of 6.6 feet to the sports floor and test the rebound height of the basketball. This data is expressed as a percentage. The rebound height of basketball on the concrete floor is the comparative standard, reflecting the difference in rebound height. Indoor rules for ball games require that, with the help of ground sports competitions or training, such as basketball and other ball movements and the rebound of the ball, the sphere's rebound coefficient on the ground of the court should be greater than or equal to 90%. The professional pvc sports floor has outstanding and stable ball resilience, there is no elastic dead point on the floor, and its rebound coefficient is up to 98%.
Movement energy return problem:
This refers to the exercise energy returned by the pvc sports floor when the athlete is in motion to improve exercise performance.
Rolling load problem:
The load-bearing load, firmness and service life of professional sports flooring must meet the requirements of competition and training. If the movable basketball stands and related sports facilities move on the floor, the surface layer and structure of the floor cannot be damaged. This is the German DIN standard. The described rolling load standards and concepts.
Plastic floor knowledge points
At present, PVC multi-layer composite plastic flooring (not artificial leather) has been used in the world to replace most of the traditional materials on the paved gym floor. Pvc multi-layer composite plastic flooring is not aging for a hundred years (so far no global natural retirement records, improper paving, except second flush). Anti-scratch performance reaches En660 standard Group T, absorbing walking noise comparable to carpets, technical performance over solid wood sports flooring and acrylic indoor sports venues, flame retardant, moisture, non-slip (water is not slippery), expansion coefficient is very low It is completely environmentally friendly and non-toxic. Resist all chemical contamination (strong corrosive contamination must be immediately removed), antistatic. Termite and other daily hazards cannot damage the floor (except improper paving). It is more convenient to remove and upgrade without special maintenance.
