Because the functions of these two sides are not the same. The red side is generally served, and the black side is generally hit. <>First of all, the red board is usually used as a serve.
It has a grain side down and a smooth rubber plane. High resistance, stable hitting and easy control. It has a thicker surface and is more elastic, so it is more suitable for chipping.
The chalkboard has a rough surface and is one of the most commonly used types of erasers for straight-line fast break players, making it more suitable for hitting the ball. ITTF stipulates that the board must be black and red, which is to allow the opponent to identify which material is used, and to prevent players from repeatedly flipping the board and confusing the players. It is convenient for athletes to make judgments, increase the number of rounds of competition, and show competitiveness and fairness.
One red one. The blackboard can improve people's concentration, not be easy to get tired, and increase the fun of the game. <> red rubber is also called short-grained rubber. It is characterized by good elasticity, fast speed, stable hitting and no spin.
It is suitable for fast attacks in the near phase, especially left push and right attack. It is one of the most commonly used types of rubber for straight fast breakers, and the average person uses a red eraser for forehand rackets. <>
Vinyl is characterized by strong spin on the ball, stable hitting and easy control, and is suitable for curve ball or curve ball combined with fast attack. Due to its stable hitting and good control, it is also the first choice for beginners, and ordinary people use black rubber for their backhand. For professional players, there are a variety of reverse rubber sponge bats with different properties to choose from, such as strong stare force glue and soft and thick matching sponges, so they have good characteristics of "biting" the ball and "wrapping" the ball.
Reverse rubber sponge rubber is currently the most commonly used rubber for straight and horizontal shooters. Almost 100% of European players use this rubber, and nearly 80% of Asian players also use it. This is because this rubber takes into account the requirements of speed and spin of the ball.
When you are playing table tennis, remember to wash the brand after the game and then put on the film.

Because the table tennis racket is divided into red and black, this is used to distinguish the performance of the rubber, the difference is that the degree of friction is not the same, and the color is different.
-
In order to allow the referee to better see the athlete's score. One side is red, the other side is black, and the materials on both sides are different.
-
Because the travel land can make the color file more eye-catching, and it can also better distinguish the two colors, so the table tennis racket is like this. The difference is very big, because then you can distinguish the pros and cons.

Table tennis is China's "national sport". Although it originated in the United Kingdom, it has been popularized in China. Whether teenagers, young adults, or seniors, they love table tennis as one of the sports to exercise their bodies and relieve stress and fatigue.
A table tennis racket is one of the most basic tools for table tennis. Common table tennis rackets always have a black face and a red face, so what is the difference between these two colors?
In fact, in the earliest period, table tennis rackets were black and red, and players could paste rubber according to their preferences. However, although the color of both sides of the racket is the same after gluing, the color after glue is different, which will result in the same shot and different effects. Cai Zhenhua, the former head coach of Chinese table tennis, uses two black rubber surfaces, but one side is reversed, and the other side is reversed, which makes the return of the ball erratic.
Sometimes turning and sometimes not turning, making the opposing players dizzy.
Later, the ITTF technical manual stipulated that the color of the rubber could only be red and black, and if one rubber of the racket was red, the other rubber must be black. This is decided for the sake of the fairness of the game. We know that there are two types of rubber surfaces for rackets:
Positive glue (with bumps) and reverse glue (smooth). The balls produced by these two types of vinyl surfaces are not the same. In order to prevent players from suddenly changing (shooting) sides during the game.
This system was originally created to deal with Chinese players. There was a group of players who switched to playing. The representative figure is Cai Zhenhua, and Cai Zhenhua's horizontal plate is double-sided, one positive and one negative.
During the game, the opponent constantly rotates the racket and is unable to accurately distinguish the characteristics of the ball. As a result of the move to make China stronger, the ITTF instituted a different-coloured rule for both sides, and Cai Zhenhua was transformed from a racer to a coach because of the introduction of this rule.
As for some people who say that they have seen yellow, the reason is that our common rubber is actually divided into two layers, the bottom plate is based on yellow sponge, and the layer above the sponge is rubber. The color of the rubber is the color we see when we watch the game. For those who have a horizontal plate and one side, the rubber side is not sticky, but in order to hold the racket comfortably, a layer of sponge is attached, and that's it.

The red and black sides of the table tennis racket represent different materials, the red side is used positive glue, the black side is used reverse glue or raw rubber, and the trajectory of the ball emitted by different rubber surfaces is different.
-
Because the rules of the game require that the rubber color of the table tennis racket can only be red or black, if the forward rubber is red, the reverse rubber must be black, so the regulation is formulated for the fairness of the competition, in order to prevent players from suddenly changing sides to hit the ball in the game.

Origin and development.
Table tennis originated in England at the end of the 19th century. Originally just a mobile game, the ball was made of a light and elastic material, and the wooden board such as the lid of the cigar box was played on the table like a tennis ball, so it was called "table tennis". >>>More
