PVC sports flooring is a kind of floor made of PVC material specially developed for sports venues. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw materials, and fillers, plasticizers, stabilizers, colorants and other accessories are added. On a sheet-like continuous substrate, it is produced by a coating process or by a calendaring, extrusion or extrusion process. It is generally formed by lamination of multi-layer structures, and generally includes a wear-resistant layer (including UV treatment), a glass fiber layer, an elastic foam layer, a base layer, and the like. In recent years, the application of PVC sports flooring has been very extensive. The Olympic Games and other international competitions have specified the use of PVC sports flooring. It can be seen that the market prospect of PVC sports flooring is very broad.

Technical Features of PVC Sports Floor

1. Comfort issues:

The surface of the professional PVC sports floor is moderately deformed when impacted, like a sealed mattress with air. When you wrestle or slip, the cushioning effect provided by 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 types of tremor: tremors and regional tremors.

3. Problems with vibration absorption:

The impulse generated by a person when exercising will cause vibration on the surface of the PVC sports floor. The structure of the floor must have the function of shock absorption. That is to say, the floor should have the ability to absorb impact energy. The athletes are opposed to 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 when the athlete is exercising, he will not be affected. hurt. Its protection function also considers that a person cannot influence the adjacent 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 a 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 coefficient of friction 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 the 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 action and the rebound of the ball, the requirements for the rebound of the ball on the ground of the competition field should be greater than or equal to 90% of the professional PVC sports flooring has outstanding and stable ball rebound performance, 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 during the athlete's movement in order 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.

Application of PVC sports floor

PVC sports flooring is widely used in various sports venues such as: badminton, table tennis, volleyball, tennis, basketball, handball, indoor soccer competitions and training venues, multi-purpose gymnasiums, gymnasiums, dance studios, schools, and union activities Room, multi-purpose hall, amusement park, kindergarten, sports shop, office, hotel, hospital, etc.

PVC sports floor application places and specifications

Table tennis sports floor

Table tennis originated in the United Kingdom. Table tennis flooring The ITTF recommends the standard color (safran), and PVC sports flooring is recommended. Because of its superior durability and wear resistance, comfortable resilience and shock absorption, stain resistance, and environmental protection are unmatched by ordinary solid wood table tennis flooring.

The use of PVC sports flooring is mainly based on the rules of motion of table tennis. The PVC sports floor has suitable friction. The friction is not good for the movement, but it will slip when it is small. The elasticity is appropriate because the table tennis moves, starts and The stops are abrupt, so this quick stop has better protection for the human knee.

Badminton floor

One of the origins of badminton is Japan. One is Britain. The Badminton Floor International Competition specifies the use of PVC sports flooring. The color is green, because the anti-slip performance and impact resistance of PVC sports flooring are better than other floors, and the stain resistance, abrasion resistance, and environmental protection of PVC sports flooring are not available on other floors. In contrast, the impact of athletes' joints can be reduced and the athletes' performance can be improved. Therefore, PVC badminton flooring is better than solid wood badminton flooring. Therefore Wanao PVC sports floor is the best choice for high-end badminton venues.

Most fine jewelry stores will not sell a Ring Box from their store. The reason is that the store's ring box and the contents of the ring box represents the store. And the store does not have any control over what ring will go inside that ring box.
This White Leatherette Ring Box is ideal for fashion and wedding jewellery. Supplied with a protective sleeve to keep the box in top condition. Dimensions: 46mm in width, 53mm in length and 40mm in depth. Please note that sizes may vary slightly
