1. Comfort issues:
The surface of a professional pvc sport floor is moderately deformed when impacted, like a sealed mattress with air. When you wrestle or slip, the cushioning effect of the closed foam back layer technology can be minimized. Sports injury.
2. 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.
3. Problems with vibration absorption:
The impulse that people form during exercise will produce vibrations on the surface of pvc sports floor. The structure of the floor must have the function of shock absorption, which means 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 hard ground, such as on concrete ground. That is, when an athlete jumps up and falls to the floor, at least 53% of the impact must be absorbed by the floor, thereby protecting the athlete's ankle, meniscus, spinal cord, and brain, so that the athlete will not be affected during exercise. hurt. Its protection function also considers that a person can not influence the neighboring person when he moves on the pvc sports floor. This is the concept of shock absorption, vibration deformation and extension deformation described in the German DIN standard.
4. The problem of friction coefficient:
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 mobility and safety, the friction coefficient should be between 0.4 and 0.7. The friction coefficient of pvc sports floor is generally maintained between this coefficient. The coefficient of friction of professional pvc sports floor is 0.57. It has sufficient and moderate friction to ensure the stability of the movement while maintaining the movement direction. The consistency and regularity of the frictional performance ensures that the flexible movement and the rotation in place are not hindered.
5. Resilience of the ball:
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 use of the ground for sports competitions or training, such as basketball and other ball movements of the take-off movement and the rebound of the ball, the requirements for the rebound of the sphere on the ground of the court should be greater than or equal to 90% of the professional Pvc sports flooring has outstanding and stable ball rebound elasticity, there is no elastic dead point on the floor, and its rebound coefficient is up to 98%.
6. Problems with returning exercise energy:
This refers to the exercise energy returned by the pvc sports floor when the athlete is in motion to improve exercise performance.
7. Rolling load issues:
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.

Indoor gardening is becoming increasingly popular among plant enthusiasts with limited space, unfavorable weather conditions, or simply a desire to nurture leafy friends all year round. While natural sunlight is always the best option for plant growth, Indoor Grow Lights have emerged as an ideal alternative in the absence of natural light. Among various types of grow lamps, LED Plant Lights have gained popularity due to their energy efficiency, adjustable light spectrum, and long lifespan. In this article, we will explore the benefits and features of LED Grow Lamps for indoor gardening, and why they are a must-have for every plant parent.
