What the new plastic table tennis is
The Paris world championships in May 2013, the international table tennis federation resolution, since July 1, 2014, including the Olympic table tennis match and world championships, World Cup and the international table tennis federation open and the finals will use safe environmental protection, in polymer as the raw material of new plastic balls.
From the processing technique, plastic table tennis adopts the "seam" processing technology, through the two hemispheres of the method of gluing, in the adhesion site to form the joint. The manufacturer tries to make plastic table tennis ball's rotation, including the drop, sound, fastness and flight path close to traditional table tennis. Because plastic table tennis also has the advantage of not flammable and explosive, reduce the enterprise cost in storage, transportation and so on.
Apart from the material, the biggest difference between the new plastic ball and the old ball is the change in the diameter. International table tennis federation rules, new ball diameter from 39.50-40.50 mm to 40.00-40.60 mm, so the size of the tiny adjustment, but enough to make the rotation of the table tennis, speed and flexibility change obviously. The international table tennis federation requires the new plastic ball to be labeled "40 +", which is distinguished from the previous "40". This means that table tennis has entered the "40 + era".
Why does the international table tennis federation change the texture of table tennis ball?
From 1891, celluloid was the material that made table tennis. Celluloid is a kind of nitrocellulose material, which is commonly known as "fake ivory". Its main components are cellulose nitrate, ethanol, camphor, etc., with strong tensile strength, and water resistance, oil resistance and acid resistance. However, its greatest drawback is that it is flammable and emits a lot of irritating toxic gases when burned. As soon as you encounter a bright fire and high heat, the celluloid ball is an air embargo. Celluloid balls produce a lot of toxic dust in the process of production, which can cause lung cancer as easily as asbestos, causing great harm to the body of the production workers. As a result, celluloid table tennis has ceased production in European countries.
How do you get ahead in the new world?
Chinese and foreign players have different adaptability to the new plastic ball. For ding ning, the most obvious characteristic of the new ball changes is that the rotation is slower and faster. Speed is not the absolute speed of the ball, but the speed of the connecting ball is faster than the previous time playing celluloid table tennis. Because the ball is now hitting the racket and there is no longer time to stay, less friction and more control. Zhang believes that the new ball has some irregularity in the service, and other things are normal.
The international table tennis federation's reform of the equipment or rules will lead to the reorganization of the original pattern. And those who quickly seize the opportunity after the reform will often create an era of their own. "Although the ping head coach liu guoliang said, the Chinese men and women players join forces with the World Cup final, the result is more normal, but look from the process, some athletes are more or less affected by the new ball, but it is not a conclusion, after all is just beginning. There is still a lot of adaptation, some adaptability, some weak, but in the end, the ability to see who is stronger is gradually becoming the dominant force.
