The characteristics of table tennis positive glue, the positive glue of table tennis What kind of gl

Zhengjiao is a table tennis term that refers to a table tennis racket.

covering, glue outwards. Also called short-grain rubber.

Features: good elasticity, stable batting. It is one of the most commonly used types of rubber for straight-board fast-break players, and is suitable for fast-break play. It is also the preferred type for beginners due to its stable hitting and good ball control.

Table tennis ball positive glue is the rubber of the racket with the rubber particles upward, the height and the diameter are equal. It is characterized by good elasticity, fast speed, stable hitting, and no turning, which is suitable for fast attack near the table, especially the left push and right attack type of play, and is one of the most commonly used rubber types for straight board fast attack players.

1. In terms of rotation, the performance of positive glue is closest to that of reverse glue, and it has a certain manufacturing rotation capacity; The manufacturing rotation capacity of raw rubber and long rubber decreased in turn. The corresponding three types of rubber are also the most popular.

2. In terms of speed, the speed of positive rubber is not as fast as that of raw rubber, but it is faster than that of long glue. The particles of the positive rubber are shorter, and the kinetic energy of the incoming ball can be returned more, that is, the speed of the ball is a little faster.

3. In terms of playing style, compared with the reverse glue, raw glue, and positive glue, the speed is fast and the rotation is weak, which is mainly used for the fast attack of the near platform or the fast play of the arc of the near middle platform, in short, it is to win with speed.

Fast speed, great power, and high hitting point, which requires a high level of pace, physical fitness, and reaction speed.

The positive rubber is characterized by strong spin force, stable hitting and easy control, and is suitable for arc circle type or arc circle combined with fast attack type play. It is also the preferred type for beginners due to its stable hitting and good ball control. For professional players, there are a variety of anti-rubber sponge rackets with different properties for late touching, such as strong adhesive rubber and soft and thick supporting sponges, so they have good characteristics of "biting" the ball and "wrapping" the ball.

Long glue is a type of glue that is covered with a thin and long rubber skin on top of a thin sponge, while the rubber sponge is rubber. Invented in the sixties. Back then, Zhang Xielin used the rubber of laughing scum Li to cut out unpredictable balls, and was known as a table tennis magician.

This is because this kind of rubber ball will produce abnormal rotation phenomenon on the paddle surface, and the typical change is: when the opponent rubs the downspin ball, when you rub it with a long rubber, the upper spin will fly back; The opponent's topspin ball, your own side pushes the block with a long rubber and then flies back with the downspin; The ball will spin more when hitting the opponent's curved ball with a chipping ball, while the ball will not spin when the ball is pulled back. These anomalous changes often make the opponent miss or return the high ball, which can often be easily won against someone who is not familiar with the performance of long rubber.

There are four types of table tennis rackets: positive rubber, reverse rubber, raw rubber and long rubber.

Positive glue: that is, the rubber particles are outward, also called short particle rubber. The biggest advantage is that you are not afraid to turn.

Features: good bounce disturbance, stable batting. It is one of the rubber commonly used by straight fast-break athletes.

Athletes using this racket: Liu Guoliang, Zhuang Zedong, Li Furong, etc.

Reverse glue: refers to the rubber with the rubber particles facing down and the surface smooth.

Features: Strong spin force, stable and easy to control. It is suitable for arc rings and arc circles combined with fast attack type hair.

Athletes who made Lu Jing use this shot: Deng Yaping, Wang Tao, Wang Nan, etc.

Raw rubber: the rubber particles are upward, and the rubber content of the rubber is higher.

Features: Easy to control the ball, there will be a significant sinking when hitting the ball, its hitting speed is the fastest of all rubber, but its stability and manufactured spin is not as good as positive rubber.

Athletes who use this racket: Tang Peng, Ai Fukuhara, etc.

Long glue: The rubber with the particles facing upwards and the height exceeding the millimeter is called long glue.

Features: The ability to actively create spin is poor, mainly relying on the opponent's strong spin or strong momentum to increase the rotation of the return ball.

Exercise practitioners who use this racket: Zhang Xielin, Lu Yuansheng, Ding Song, etc.

The rubber particles are positive glue on the top, and the rubber surface is reverse glue on the top. There is a difference between round and square heads, that is, raw rubber and long rubber. I played ball as a pair of double happiness rackets given by Uncle Six, from the stone platform, all the way into the school's sports group, one day the teacher won, the teacher caught me and said:

Boy, you're so daring、、、 come back tomorrow!

Don't think so much, what you can see in the official competition is a smooth reverse glue on the paddle surface, and the granular positive glue is rarer than the straight shot, as for the raw rubber long glue, the particle length diameter ratio is just different, the most important thing for you is to listen to Deng Yaping's explanation, don't be taken to the ditch by Yang Ying as a pig.

The difference between long glue and raw rubber is:

1. Long glue

The length of the particles of the long rubber can generally reach more than millimeters, the main feature of the long rubber rubber is that the elasticity is particularly good, which leads to the sinking of the long rubber back to the ball, erratic, often there will be abnormal rotation phenomenon, often use knock, arch and other ways to play, many people turn the long rubber into a strange glue, before Deng Yaping is a long rubber play, now the grandmother Ni Xialian is also a long glue, there are no other professional players.

The core of the long rubber style of play is to make the opponent miss. With the help of the opponent's force, the trajectory sinks or the trajectory is erratic after returning the ball, and many amateurs lose the game by making continuous mistakes against the long rubber.

2. Positive glue

The positive rubber is a short-grain rubber, the particles are outward, and the length of the rubber particles is basically equal to its diameter. The biggest advantage of positive rubber is that it is not afraid of spinning, has good elasticity and is stable in hitting. It is one of the rubber commonly used by straight fast-break athletes, and it must be fast if you want to give full play to the advantages of positive rubber.

The core tactic of the positive rubber play is to play a board, either through the serve, or through the other side of the reverse to find an opportunity to pull a board, or through various transitions, find an opportunity to play a forehand to end the battle. Liu Guoliang is a representative of this style of play, and in the later period, the International Table Tennis Federation did not allow the serve to be blocked, and used the big ball to slow down the tempo, which also led to Liu Guoliang not being in his peak when he retired.

3. Raw rubber

The content of colloidal particles in raw rubber is larger than that of positive rubber, and the colloidal particles are softer and more elastic. The characteristic of raw rubber is that the ball is out quickly, and the ball that is hit out sinks faster than the ball hit by other rubber. Due to the small friction, the ball that is returned to the past does not turn the ball, and it is a little fluttering, which is not conducive to the opponent's attack.

Raw rubber play needs to enter the most ruthless fight rotation, at present, Ito Misei is a forehand backhand rubber, generally speaking, forehand raw rubber through a large power smash to end the game, or backhand raw rubber pulled out of the return ball without turning to find a chance to smash, in addition to raw rubber is easier to control the ball than long rubber, backhand bounce is also an important means of scoring. The raw rubber players are simply decisive and take the initiative to control the pace of the game.

The difference between table tennis raw rubber and positive rubber: different particles, different characteristics, and different types of use.

1. The particles are different.

The rubber particles of the positive rubber racket are upward, and the diameter of the particles is equal to the height of the Huai Bureau particles from the rubber surface, and the particles are short and hard; The rubber particles of the raw rubber racket are upward, and the diameter of the particles is greater than the height of the particles from the rubber surface, and the particles are short and soft.

2. The characteristics are different.

The characteristics of positive rubber are good elasticity, stable hitting and fast lead spring ball speed, but the ability to create spin is weaker than that of reverse glue, and it cannot pull out a strong arc ball due to small viscosity; The characteristic of raw rubber is that the ball is slightly sinking, and it does not eat much spin, and because the raw rubber has the effect of reducing rotation, it is especially easy to control the ball.

3. Different types of use.

If you feel that your wrist movements are flexible, and the strength of your arms and waist and abdomen is not enough, then the rubber racket is the best choice; Raw rubber is suitable for players close to the table, especially when dialing the short ball in the table with the backhand.

Selection tips for table tennis

1. Appearance. The surface of the ball must be fine and non-reflective, and the waist seams of the Mori Town ball are neat and crisp.

2. Roundness. Place the ping pong ball on a smooth, flat surface and rotate and observe for violent**. It means that the roundness of the ball is not good, the stability of the ball is poor, and the landing point of the ball is not easy to control.

3. Hardness. Pinch the pre-part of the ball with your thumb and index finger to see if the softness and hardness of the two sides are consistent. If the degree of ** is the same, it means that the hardness quality of the ball is better, and the performance is better.

4. Bounce height.

The ** height of throwing the ball from a height of 305mm onto a standard table tennis table is between 235mm and 255mm. If the bounce of the ball is high or low, it means that the elasticity of the ball is uneven.
