Why do table tennis rackets have front and back stickers?

Playing table tennis, in addition to the skill of the player swinging the racket, the role of the racket is also very important. For a table tennis player, the racket is like the ** in the hands of a warrior.

With the continuous development of table tennis technology in the world, the technology of various playing styles is also constantly innovating, and there are more and more types of table tennis rackets.

Once upon a time, we used wooden paddle rackets to play table tennis. Due to the lack of power and friction of the racket made of wood, the playing speed was very slow at that time, just pushing around, and when there was an occasional high ball, it could be stormed.

Later, the rubber paddle appeared, and the rubber surface was covered with small particles of soft body, and when it came into contact with the racket, it was not only a point on the ball like a wooden paddle, but a curved surface. Due to the deformation on the rubber paddle surface, the contact area is expanded, and the friction is increased, resulting in the rotation of the ball, and it is easy to create an arc when hitting the ball, which improves the playing technique.

In 1952, the sponge racket appeared, which further developed the playing technique. Because the sponge is very soft, it is full of fine pores and elastic, when hitting the ball, the ball touches the sponge, and the sponge body is concave inward under the pressure of the ball, the sponge is elastic, and the table tennis ball is also accelerated and the strength increases under the elastic action. However, the pure sponge racket, due to the lack of friction, is not easy to control the accuracy of the ball and produce the rotation of the ball, so the athlete came up with a good way - to put a piece of rubber with rubber particles no more than 2 mm thick on the sponge layer.

This auspicious has the elasticity of a sponge and the stickiness of a rubber control ball.

Why is the rubber on the racket sponge some of the front stickers (the particles are on the outside) and some are the reverse stickers (the particles are on the inside)? This involves the different characteristics of the two rackets, as well as the different requirements of players for the racket, what kind of play, what kind of racket to choose.

For example, fast-attacking athletes generally use positive adhesive combined with sponge. Because the positive rubber is stronger than the reverse rubber, its particles are outside, the contact surface between the rubber and the ball is small, the stay time is short, and the ball speed is fast, which is conducive to the characteristics of fast attack athletes to speed up the attack and the strength is heavy.

The other is a reverse rubber combined sponge, which is generally used by arc balls and chippers.

The curve ball and the chipping ball are both spin-based, the arc ball is an upward rotation, and the chipping ball is a downward rotation, and both styles of play focus on playing rotation.

The reverse rubber has the characteristics of rotation, because the reverse rubber particles are inside, its surface is rich in viscosity, when the ball is slapped, the contact area between the racket and the ball is large, and it is easy to make the friction force act on the ball, so the rotation produced by this racket is much stronger than that of the positive racket. At the same time, because there is an extra layer of rubber particles between its rubber surface and the sponge layer, there are many gaps between the rubber particle layer, when the racket is in contact with the ball, the racket is more concave inward, and the contact surface between the racket and the ball is larger, and the friction force increases, and the athlete relies on this friction to make the ball spin more violently.

Pure sponge rackets, due to the lack of friction, it is not easy to control the accuracy of the ball and produce the spin of the ball, so the athlete came up with a good way - to put a piece of rubber with rubber particles no more than 2 mm thick on the sponge layer. This auspicious has the elasticity of a sponge and the stickiness of a rubber control ball. The different characteristics of the two rackets, as well as the different requirements of the players for the racket, what kind of play, what kind of racket to choose.

The positive rubber is stronger than the reverse rubber, its particles are outside, the contact surface between the rubber and the ball is small, the stay time is short, and the ball speed is fast, which is conducive to the fast attack athlete to speed up the attack speed and the characteristics of heavy strength. The reverse rubber combined with the sponge is generally used by the arc ball and chipping players.

Also called short-grained rubber, characterized by good elasticity, fast speed, stable hitting, no turning, suitable for near the Taiwan fast attack, especially the left push and right attack type of play, is one of the most commonly used types of rubber for straight board fast attack players, in the past, Zhuang Zedong, Li Furong, Jiang Jialiang, Xie Saike and a large number of world champions have used the rubber sponge straight shot. Today's world champion Liu Guoliang also uses this type of rubber.

The positive rubber is stronger than the reverse rubber, which meets the friction required when playing.

In order to solve the problem of too little friction when playing.

Good elasticity, fast speed, stable hitting, no turning, suitable for fast attack near the table, especially the left push and right attack type of play.

In order to meet the needs of athletes to play backhand rackets.

Good elasticity, fast speed, stable hitting, no eating and turning, suitable for fast attack near the table.

In this way, the ball can be played quickly and accurately, and meet the needs of playing.

Zhengjiao is also called short-grained rubber, characterized by good elasticity, fast speed, stable hitting, no turning, suitable for fast attack near Taiwan, especially the left push and right attack type of play, is one of the most commonly used types of rubber for straight board fast attack players, in the past, Zhuang Zedong, Li Furong, Jiang Jialiang, Xie Saike and a large number of world champions have used positive rubber sponge direct shooting.

Today's world champion Liu Guoliang also uses this type of rubber.

If you feel that your wrists are flexible, but your arms and waist are not strong enough, it is best to choose a positive rubber racket with speed to win.

At present, there is a kind of medium particle rubber between short particles and long particles in the international market, which has the peculiar effect of non-spin attack, and the opponent attacks the strong volley or downspin ball, this kind of rubber is not afraid at all, and it is not spinning the ball in the past, and it is erratic, so that the opponent can not make it hard.

It's known as the "Magic Gel Skin".

Anti-glue is characterized by strong spin force, stable hitting and easy control, and is suitable for arc circle or arc circle combined with fast attack type play.

Because the shot is stable and the ball is well controlled, it is also the preferred type for beginners.

For professional players, there are a variety of anti-rubber sponge rackets with different properties to choose from, such as strong adhesive rubber and soft and thick supporting sponges, so they have good "biting" and "wrapping" characteristics.

The reverse sponge rubber is the most commonly used rubber for straight and horizontal players, almost 100% of European players use this kind of rubber, and nearly 80% of Asian players also use this kind of rubber.

Because this kind of rubber is a good balance between speed and rotation requirements.

At present, most of the world's super-first-class players use anti-adhesive rubber.

For example, Waldner, Persson, Seifer, Ma Wenge, Wang Nan, etc., who combine arc circle and fast attack play, Gai Ting, Wang Tao, Kong Linghui, Deng Yaping, Li Ju, etc., who combine arc circle play, and Ma Lin, Yan Sen, Feng Zhe, etc., who hold the racket straight, are all reverse rubber on the front or both sides.

Players who play anti-glue hope that the rubber has a high wrapping force, that is, the rubber surface must be sticky, so as to have a high friction coefficient.

In addition to professional athletes who have the conditions to play the game and change the rubber to destroy the state book, amateurs may not have this condition, so they must know how to protect the stickiness of the rubber.

The easiest way is to clean it with a soft foam sponge dipped in water after each exercise, and there are also special detergents on the market**, which will be better to use.

After cleaning, cover with polyester film, which protects against both dust and oxidation.

Summary. Increase the enjoyment of the game, a moment of black, a moment of red, not only improve people's attention, not to get tired, but also play a role in confusing the other party! Make the other person uncomfortable

The red and black sides are more eye-catching, and they are opposite to the color of the light, otherwise if there is white rubber, it will be reflective!

Why are the red and black rubber of some table tennis rackets upside down?

Table tennis rackets are black and red (there is no rule as to which side is black and which side is red) is regulated by the ITTF.

Increase the enjoyment of the game, teasing friends black for a while, red for a while, which can not only improve people's attention and not get tired, but also play a role in confusing each other! Let the other party not adapt to the "red" and "black" two-sided cracks are more eye-catching, and the color of the light is opposite, otherwise if there is white rubber, it will be reflective!

It's that he originally had a marked surface that was red, and the unmarked lead side was black, and then he is now a reverse wheel, coming over with a marked side is black, and the unmarked side is a red Huaizi chain.

There is only one auction label, which is the wrong label during production, and the prenatal inspection is released, resulting in the flow to the market.

So I'm lucky or unlucky.

Ha ha. Fortunate.

In order to meet the needs of table tennis players with different playing styles, the front and back of table tennis rackets are provided with vinyl surfaces. Generally speaking, the positive glue is the glue with the particle shot, and the reverse glue is the flat rubber, which is hit by friction, and by using the rubber with different properties, the rotation speed of the return ball is significantly different by changing the grip, so that the opponent is not adaptable, or directly scoring or controlling the opponent.

The difference between the front and back glue of the table tennis racket.

1. The direction of the rubber particles is different.

Positive glue is a table tennis racket covering, and the rubber particles are outward, also called short particle rubber. Reverse glue refers to a rubber with the rubber particles facing down and a smooth surface.

2. The characteristics are different.

The positive rubber is characterized by good elasticity, stable batting, and easy to play the role of sponge and bottom plate, which is conducive to improving the speed and power of batting. The reverse glue is characterized by strong spin force, stable hitting and easy control. Because the surface of the rubber is very soft and sticky, it is not easy to slide when the ball is in contact with the rubber surface, so it is conducive to increasing the rotation of the ball.

How to choose a table tennis racket.

1. Racket weight.

The heavy plate is conducive to borrowing, but it is not conducive to active force, and it consumes too much physical strength of the old individual. The light plate is conducive to active force, and the borrowing force is worse than the heavy beat, which is conducive to maintaining individual physical strength. Therefore, the selection of the racket should not only be conducive to active force, but also take into account the borrowing force and save effort, but also maintain physical strength, the total weight of the racket should not be too heavy, not too light, in order to hold the board does not feel laborious, do not feel the weakness of the racket shall prevail.

2. The feel of the beat.

The handle is comfortable and fits snugly – it fits into your hand. It is recommended to use a tapered handle - there will be no uncomfortable feeling such as inappropriate shooting. The board surface should not be too large or too small - too large the board surface will affect the accuracy of the racket; The board surface is too small, which is not conducive to the smoothness of the streamline of the racket.

The shape of the board surface should pay attention to the streamline - the shape of the board head is too sharp or the patter surface is too round, which is not conducive to the play of skills and tactics.

3. Rubber pasting method.

Popularize the comprehensive play method and recommend two-sided anti-glue. Double-sided reverse glue is good for mastering the rotation and other control of the ball; Positive glue is not conducive to rotation, especially the use of push gear. Raw rubber is more powerful than ordinary rubber to hit the ball, suitable for enthusiasts with a certain foundation, and raw rubber can be applied to popularize the nuclear celebration method.

Long glue is not included in the list of regular competition equipment, and it is recommended to prohibit it.

The reverse glue is the smooth side, and the positive glue is the opposite. When hitting the ball against the glue, you can turn the downspin ball into an upspin ball, and the upspin ball is fast. The anti-rubber friction is large, the elastic force is small, and the positive glue is the opposite.

Positive glue, the rubber particles are outward, that is, there are many small protrusions, and most athletes who shoot directly near the table to push left and right or attack on both sides like to use it. Since the height of the rubber particles is generally between millimeters. This kind of rubber not only has good stability when hitting the ball, but also has a large force, which is easy to play the role of sponge and bottom plate, which is conducive to improving the speed and strength of hitting the ball.

However, because the glue content of the colloid is not very large, the particles are relatively hard and lack of viscosity, so it is far inferior to the reverse glue in terms of friction ability.

The reverse glue is smooth, and the gum particles are inward, that is, towards the sponge side. This kind of rubber is very soft and sticky because the surface of the rubber is very soft, and it is not easy to slide when the ball is in contact with the rubber surface, so it is conducive to increasing the rotation of the ball.

Raw rubber, raw rubber rubber is very similar to positive rubber rubber in terms of specifications, and the height of the particles is generally between millimeters, but the rubber content of the colloid is larger than that of the positive towel rubber, so the particles are softer and more elastic. When hitting the ball, in the case of heavy hitting, the stability is better, which is conducive to eliminating the strong topspin of the curved ball, but in the case of light hitting, the stability is not as good as the positive glue, which is easy to make the ball float.

Long glue is generally used on both sides of different performance rackets to sharpen mainly athletes like to use. The colloid of this rubber is soft, and the height of the particles is between millimeters. Due to the slender size and low support force of the rubber particles, the particles are prone to tilt when subjected to incoming ball pressure.

In the case of light ball force or weak topspin, the slope of the particle is less after being forced, but its ** speed is very fast, and the ball is often ejected before the player uses the force to cut the ball, so it is more difficult to add spin. In the case of heavier incoming ball force or strong topspin, the particle has a greater inclination after being stressed, and the ** speed will be relatively slowed down, and the particle is also returning to its original state when cutting the ball hard, which plays a whipping effect on the ball, thereby increasing the rotation of the chipping ball. The performance of long glue, which is stronger and stronger and weaker and weaker with less force, is the opposite of the performance of reverse glue in chipping.

Positive glue, the glue particles are outward, that is, there are many small protrusions, this glue is fast, but the rotation is not as good as the reverse glue, and the control is not very good. The reverse glue is smooth, there are rubber particles then it is inward, that is, thinking about the sponge side, this smooth design makes the reverse glue extremely sticky, making it rotate strongly, but the speed is not as good as the positive glue. In addition, raw rubber and long rubber are also plastic particles outward.
