What is long glue and short glue table tennis ?

Long glue is a kind of strange glue, there are many grains on the rubber, the grains are relatively long, and it is the longest grain in the table tennis rubber! There is no such thing as short glue in the proper noun!! The kind of rubber without grains is called reverse rubber, the one with very short grains is called positive rubber, and the rubber that is longer than the positive rubber but shorter than the long rubber is called raw rubber!

In table tennis, in general, the rubber with the particles facing upwards and the height exceeding millimeters is called long glue. The rubber particles of this rubber are very soft, the particles are elongated, and the support force is small. The ability to actively create spin is poor, and it mainly relies on the strong spin or momentum of the incoming ball to increase the spin of the return ball.

The rubber surface is divided into reverse rubber, raw rubber, positive rubber, long rubber, etc., while short glue may be some names for individuals.

Ping pong boards are divided into straight and horizontal boards. The board is composed of a base plate, two sides of the rubber surface, and two sponges. The rubber surface is divided into reverse rubber, raw rubber, positive rubber, long rubber, etc.

Sharpening and rubbing players are recommended to use one side of the reverse glue and one side of the positive glue. Fast breakers are advised to use one side of the reverse glue and the other side of the long glue. Players who draw the arc ball are advised to use double-sided reverse glue.

Long glue is a granular rubber in the longer rubber particles, like a brush, often change the rotation of the ball, the reverse rubber rubbing the past downspin long rubber knocked over into the top spin, the reverse glue pulled over the top spin long rubber to prevent it from becoming downspin. Of course, due to the difference in the length of the rubber particles or the curing treatment, the ball properties of the long rubber are also different, and the amateur world uses a lot, and the results are faster, while it is difficult to play to the top level in the major.

Table tennis long rubber is the particle upward, the height of more than a millimeter of rubber, the long rubber rubber is very soft, the particles are slender, the support force is small, but the ability to create rotation is very poor, when used mainly rely on the rotation of the ball to increase the rotation of the ball.

Long glue, as the name suggests, is a longer particle of positive adhesive rubber. The length of ordinary rubber particles is about millimeters, and the long rubber particles are generally between millimeters, and the rubber is soft, which belongs to low-viscosity rubber and is not easy to eat.

The long rubber touches the ball at the moment the rubber particles show an inverted shape, the long rubber due to the long glue front of the grain is longer, after the ball and the racket contact, the rubber particles first dump and then restore the process of the ball with obvious reverse rotation, the ball spins up, and the ball spins down; The incoming ball spins down, and the return ball spins upspin. It is extremely difficult for the other party to adapt. When the opponent's incoming ball is light or does not spin, the return ball does not turn; When the opponent has more power and spin the incoming ball, the return ball will also spin more.

Main applications of glue:

Long glue is granular glue, the friction coefficient is low, the ball is relatively heavy, can not actively create rotation, to form reverse rotation by rotation as the main form of change.

The long glue treatment topspin ball is mainly knocked, and the reverse rotation makes the return ball become a downspin, and the table or half-height should be selected to pull, and the short ball should be selected to be rubbed.

The long rubber treatment downspin ball is mainly arched, and the reverse rotation makes the return ball become topspin, and the ball will be a little back from the table forehand or backhand bounce.

The long rubber treatment does not rotate the ball to push, the return ball is a little heavy does not turn the ball, with a little friction to play the long rubber afraid of the long ball, the return ball must be long and top, especially the rubbing ball, can not give the long rubber enough power space.

The longer the ball spins, the more the ball is spinned, the more the ball is spinned, and the more your ball spins, the more the ball is spinned.

1) Advantages of long glue 1The long rubber has a spin borrowing function, and abnormal spin occurs during the hitting of the ball. For example, if the opponent comes with a topspin ball, the long rubber return ball is downspin, and if the opponent returns the ball with downspin, the long rubber will turn the ball into an upspin ball.

2.Long rubber is not easy to eat and turn, which is good for receiving the serve and attacking downspin. 3.

The unique hitting block of long rubber in defense makes the ball become a sharp downspin, and it is erratic, not going forward, so that the opponent can not borrow strength.

4.The long rubber attacks the ball and sinks, so the long rubber is suitable for attacking the ball near the table. 5.

When a long rubber player uses a chipping ball to catch the arc ball, the return ball is easy to control and the return threat is great, which is a very strong downspin. 6.When dealing with the ball in the table, the long rubber has a good swing short effect, which will make the opponent who does not understand the long rubber make inexplicable mistakes; The opponent who is familiar with the long rubber also needs a certain amount of time to adapt, so it is very beneficial to the long rubber players during the game.

7.Due to the many changes in the rotation of the long rubber return ball, the opponent should judge and adjust the action in time in the game, so that the invisible long rubber will increase the psychological pressure on the opponent. 8.

The long rubber serve also has a certain advantage. When Chang Jiao finds the spin ball, the ball floats again, but the opponent will mistake it for a running ball, resulting in eating the serve; The long rubber according to the ordinary downspin service action of the ball, the opponent will mistakenly think that it is downspin, to rub or lightly pick but the return ball will be high, the long rubber player can take the opportunity to kill a board.

9.The long rubber playing method is full of changes and is difficult to figure out. Make it difficult for opponents to adapt.

1.The disadvantage of long rubber is that it can not be as effective as the reverse glue to take the initiative to create rotation, easy to be subject to the other party, when encountering the long glue has a discipline, the first three board technology is good players, the advantages of long rubber will be difficult to get full play. 2.

Because when hitting the ball, the long rubber belongs to the granular rubber, lacks support, and the ball is easy to slide on the surface of the rubber, so it is difficult to produce strong friction, and you can only borrow the rotation of the opponent's ball if you want to produce rotation. 3.The low ball attack of Changjiao is not easy to hit the ideal flight arc, the attack speed is slow and does not rush forward, and the mid-to-far platform attack has a low hit rate, which limits its offensive ability.

Therefore, the threat of the long rubber player's attack will be lower after the opponent retreats, and even due to the sinking characteristics of his own attack, it is more conducive to the opponent to control the arc when slicing the ball. 4.In addition to the obvious opportunity ball, the force can not be too violent, in dealing with the relationship between fierceness and stability, it should be biased towards stability to avoid mistakes, and the long rubber with a strong smell is even worse.

5.When the ball that is not rotated or topspinned by the long rubber rubber, and the ball that is blocked back is not of high quality, the opponent only needs to push hard or press the racket shape to only hit without pulling, and then it can easily break through.

In terms of receiving the serve, if the opponent does not send a ball that does not rotate, the long rubber uses a light block, swing short, and rubbing the ball to receive the ball is not too turned, and the opponent sends and turns the ball downspin, and the long rubber uses the same method to receive the ball into topspin, because the spin is not strong or with topspin, so the quality of the return will be attacked if it is slightly worse. The method of pulling is more stable, but it is easy to be knocked back by the other party if you don't pay attention to the landing point. 7.

The long rubber is not easy to master, and the feel of the long rubber players is demanding.

Table tennis rubber is generally divided into 4 types, and the characteristics are as follows:

Positive rubber, also known as short-grained rubber, is characterized by good elasticity, fast speed, stable hitting, and no turning, suitable for fast attack near the platform, especially the left push and right attack type of play, which is one of the most commonly used rubber types for straight board fast attack players;

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

Raw rubber, which is a rubber with particles pointing upwards and a diameter greater than the height. It is characterized by sinking of the ball and weak spin of the ball;

Long glue, a kind of glue thin and long rubber covered with a thin sponge, was invented in China in the sixties. It is characterized by abnormal rotation of the ball on the paddle surface.

There are the following differences between long rubber and raw rubber in table tennis:

1. The rotation is different, and the manufacturing and rotation capacity of raw rubber and long rubber decreases in turn. In addition, the long rubber has the performance of reverse rotation, simply put, it is to rub out the top rotation and play the bottom rotation, while the raw rubber cannot.

2. The speed is different, the speed of raw rubber is the fastest, while the long rubber is poorer.

The reason is that the long rubber particles are long, and the field will lodging when touching the ball, and the potential energy of the incoming ball is partially converted into the potential energy required for the lodging of the rubber particles, resulting in poor elasticity of the long glue.

The particles of raw rubber are short, and the above problems are not present, but relatively speaking, natural rubber is more elastic than vulcanized rubber, and it is <>

3. The characteristics are different. The main feature of long rubber is that the ability to actively manufacture rotation is very poor, mainly relying on the strong rotation or strong momentum of the incoming ball to increase the rotation of the return ball.

The ball line cut out of this rubber skin is strange and unpredictable.

Raw rubber is particularly easy to control balls. At present, a group of cross-shot two-sided attackers, in order to obtain the change of the shot, adopt the combination of forehand backhand (arc circle) and backhand raw rubber (fast dial and swing short).

In table tennis, there is no short glue, only positive glue, reverse glue, long glue, etc.

Long rubber because the rubber particles are longer than the pin, after the ball and the racket contact, the process of dumping and then recovering the rubber particles is longer than the raw rubber and positive rubber of the short particles, so the ball hit by the long rubber falls to the opponent's table.

It has a significant sinking, which makes it extremely difficult for the opponent to adapt, and it is easy to make mistakes when returning fire. When the opponent's incoming ball is light or does not spin, the return ball does not turn; When the opponent has more power and spin the incoming ball, the return ball will also spin more.
