How to tell whether a ping-pong bat is good or bad?

Feel for yourself that the elasticity of the racket on the sea is different, which is very different. The racket with high friction is easy to rotate and the landing point is easy to control, but the speed is slow; A racket speed block with low friction, such as positive glue, makes the ball float. There are many flexible beats in the market, just to find a suitable matching point in these two aspects to adapt to different people.

The more expensive the racket, the better. The elasticity, friction and persistence time of the racket determine the individual's technical style and basic movements, which should be chosen according to one's own habits.

Wang gave me his racket. I may not be useful. I play very well with my 100 racket.

Table tennis bat consists of three parts: bottom plate, sponge and rubber. From these three aspects, we can basically grasp the overall quality of a racket.

Bottom plate: when looking at the quality of the bottom plate, first look at whether the bottom plate is flat or not. You can put the bottom plate flat on the glass plate, and gently click on the top, bottom, left and right parts with your fingers to see if the bottom plate is shaking. If the shaking is large, it means that the bottom plate is uneven and it is an unqualified product. If there is a slight shaking, it is normal. Secondly, hold the handle with one hand, bend the index finger of the other hand, and pat all parts of the bottom plate with your knuckles (with even force). If the sound is basically the same, it means that the elasticity is uniform; If the sound difference is large, the elasticity is uneven.

Sponge: First, look at whether there are obvious holes or impurities in the sponge appearance, and then press down with the middle finger. Generally, the sponge with hard touch hits the ball faster, and vice versa, but no matter whether it is soft or hard, the finger should have a certain rebound feeling when pressed. If there is no such feeling, it means that the quality of this sponge is poor.

Rubber: First of all, it depends on whether the color is pure and bright and whether the color is uniform. Secondly, check whether the pattern on the tooth particles is clear, and whether the size and row spacing of the tooth particles are uniform; Anti-sticking depends on whether the leather surface is flat or not. The most important thing is how much rubber there is, but too much rubber is not good.

Generally, it can be recognized as follows: put a ping-pong ball on the table, press the racket on the ball, and then lift it quickly. At this time, if the ball feels lifted, it means that the glue is good, so the rubber friction is large and it is easy to rotate.

Answer 2 to the question. What's the difference between K series and F series of double happiness table tennis bats? Which is better?

K series is very old, and F series is relatively new, but neither of them is professional, so it doesn't matter who looks professional at all. I have to say that the rubber of K series is not as good as that of F series. For example, the rubber of the old 4-star racket (such as 4006) is PF4, while the rubber of the old 3-star racket (such as 3006) is 65 12, while that of the F2006 and F3006. But the finished product can only be used as an introduction at most, even if you buy a 6-star or hurricane series. Don't look at retail rubber, floor, etc. (Double Happiness), these are expensive and have high coefficients, but what is used to make a brand is completely marginal waste compared with it. If you insist on buying it, I suggest buying the F series, but there is no need to buy 5 stars. In fact, 2 stars is enough to get started. If you want to play better in the future and pursue high cost performance and high configuration, you can choose to match a lens. If you think it is still useful, please use it. If you are not stingy, I hope you can add a little reward. After all, it is still difficult to connect with investigation, thinking and typing, don't you think?

Question 4: What are the positive and negative glue, long glue or short glue in the table tennis board? What is the difference?

Of course, it's very different. For example, Liu is a traditional fast-break game, but it is rarely used now. There are table tennis players in our family, but unfortunately, it is difficult to explain these problems at present.

Here is an online article.

Generally, rubber covers are divided into reverse rubber, raw rubber and positive rubber (because long rubber is cancelled, it will not be introduced here). The anti-sticking and anti-paste surface is smooth and sticky, which is suitable for arc playing; Positive glue is directly attached, with colloidal particles on the surface and no stickiness, which is suitable for fast attack and has a certain defensive effect on the arc; Raw rubber is attached, but the rubber particles are shorter than the positive rubber and have a certain viscosity, which is suitable for fast attack. Generally, a sponge with hardness of 40 ~ 50 and thickness of 1.8 ~ 2.2 mm can be selected for reverse gluing. Generally, 40 ~ 45 is suitable for fast break, and 45 ~ 50 is suitable for arc. The thicker the thickness, the stronger the speed and rotation, but the worse the control. Generally, 2.0mm is more suitable for amateurs. The hardness of the positive rubber sponge is generally 35 ~ 40, and the thickness is1.8 ~ 2.2 mm. The hardness of the raw rubber sponge is generally 35 ~ 40, and the hardness is1.5 ~1.7 mm. The choice of the general racket will coordinate its overall skills and tactics.

How to choose a good table tennis bat for yourself

Choosing a good table tennis bat for yourself is not only the wish of every athlete, but also the wish of every table tennis enthusiast. In table tennis, the techniques of fast attack and loop ball attack, which combine speed and rotation, have become the mainstream at present. This is because using the anti-sticking sponge racket to hit the ball, not only can we get the rhythm speed needed for fast attack near the table, but also we can get a faster flying speed when hitting the ball vigorously. Moreover, due to the high friction coefficient of anti-sticking, it is easy to produce strong topspin when hitting the ball, and sometimes the ball will rush forward quickly because of the strong topspin when landing on the table. Therefore, it is easier to get more winning factors by using the anti-sticking sponge racket when attacking on the stage, near the stage or leaving the stage, so most people choose to use the anti-sticking sponge racket. However, modern table tennis still contains many different styles of play, techniques and tactics, which will put forward different requirements for the performance of the racket, so it is necessary to find out different technical types and tactics.

The types of table tennis are usually divided into the following categories:

(1) Fast break near the table-this is the traditional playing style of China table tennis team in the world table tennis field for decades. Players who use this style of play usually use a positive rubber sponge or a reverse rubber sponge. World champions Liu and Deng Yaping are the best in this kind of competition.

The fast break near the table first requires a fast hitting rhythm, and strives to grasp the rising point and the highest point of the incoming ball on the table. The range of hitting action is small, and various methods such as breaking the country and exerting force are used. In order to improve the explosiveness and suddenness of small moves, players usually choose a heavier racket first. The weight of the racket bottom plate covered with sponge glue on one side should be about 95g, and the weight of the racket bottom plate covered with sponge glue on both sides should be lighter, generally below 90g.

In order to improve the speed of the ball, the near-table fast-break players require the hitting arc to be as low and flat as possible, so they usually use the technology of less friction and more hitting to make the ball leave the board faster, such as fast action, fast pull, fast break, bounce and smash. This requires that the sponge should be soft and thin, and the bottom plate should have a firm sense of impact, so players generally choose a seven-layer plate or a thick bottom plate with a thickness of more than 6.5 mm 。

In order to ensure the speed of attacking the ball near the table, fast-break players usually choose positive glue with outward particles or reverse glue with moderate surface viscosity, short particles and fast speed. Positive glue is a kind of hard rubber with outward particles, which can also rotate to some extent. Usually it should be matched with the thickness 1.8-2. 1 mm, and the hardness is about 35 degrees. Anti-adhesive should be equipped with sponge, the thickness is 1.5-2.0 mm, and the hardness is about 40 degrees.

(2) The fast break of the loop ball-this is a plum style of play that combines the rotation and speed of the loop ball, which is the mainstream play at present. World champions Kong, Wang Nan and Li Ju. All belong to this play. The athlete lifts the cotton racket with anti-sticking agent.

The fast attack of loop ball requires the unity of rotation and speed, so the "whip-drawing" attack technology combining friction with volley, such as picking, pulling, tearing, reversing, wiping and skimming, is often adopted. In order to ensure enough friction and bounce speed when hitting the ball, the ball wrench should not only have enough depth to eat the ball, but also have enough bottom strength. Therefore, athletes choose single wood with soft wood and good elasticity. The fast-break technique of loop ball uses more changing speed and rhythm in a wide game, from time to time, from time to time, from time to time, from time to time, from time to time, from time to time, from time to time, so it not only has a large moving range, but also has a larger hitting range and more independent strength, which requires the racket to be lighter to ensure that it can swing freely and feel better when hitting the ball quickly. Therefore, the straight plate is generally about 85 grams, especially the straight plate covered with sponge glue on both sides is lighter; The transverse plate should also be below 90 grams.

In order to ensure the rotation of arc tapping, anti-adhesive with good surface viscosity and slightly longer particles should be selected; In order to ensure the attack speed, we should choose hard sponge (above 45 degrees) and thick sponge (2. 1-2.2mm).

(3) Fast break combined with loop ball attack-This style of play combines fast break technology and loop ball technology and has the characteristics of two styles of play. Usually, it uses rubber sponge rackets or rubber sponge rackets, such as world champions Wang Tao and Wang Chen, and national team players such as Yan Sen and Ma Lin.

The attack mode of fast break combined with loop ball requires choosing a ball board suitable for both fast break and loop ball for the combination of fast break and loop ball. Those who use more loop balls should choose a soft and thin five-layer bottom plate, and those who use more fast-break techniques need to choose a hard and thick seven-layer bottom plate. The thickness of the bottom plate is generally about 6.5 mm, the weight of the bottom plate with sponge glue on one side of the straight plate is about 90 g, and the bottom plate with sponge glue on both sides is below 85 g; The weight of the selected transverse plate is usually between 90 and 95 grams.

You can choose a sponge with a thickness of 2. 1 mm and a hardness of about 45 degrees to swing back. Because most backhand attacks of diagonal ball are near the table, the sponge used for backhand hitting is thinner than forehand, which is more conducive to the application of fast break technology.

Some people choose to use raw rubber sponge for fast break. Raw rubber is a kind of positive rubber with soft gum, large elasticity and large particles. Used to attack the ball quickly, but the rotation is poor, so the attack arc is relatively flat (sinking), and the corresponding sponginess is 1.8-2.0 mm, and the hardness is about 35 degrees. Some people also use long glue or semi-long glue to attack. Long rubber particles will be overwhelmed by the incoming ball at the moment of hitting the ball and immediately rebound from different directions, so it is not easy to rub the incoming ball to make its own rotation, so hitting the ball often has the reverse rotation of the incoming ball. At the same time, because the particles falling in different directions are not equal and the direction of rebound force is different, the arc of returning the ball is erratic. The thickness of sponge usually used for long rubber tapping is 1.0- 1.5 mm, which has high hardness, which can not only keep a certain hitting speed, but also make the return arc drift and sink.

(4) Combination of attack and chop-Although this style of play is called combination of attack and chop, it is by no means a 50% attack and chop. Some people use serve attack and chop counter-attack as the main scoring methods, while chop is just to disturb opponents and create opportunities. Such as Ding Song, the world champion. At first, many people thought he was a defensive player, but he suffered a big loss because of the defensive ball. Some people take the change of direction as the main scoring method, and the attack is only a means to disturb the other side's war situation, such as the national player Wang Hui.

In order to ensure the rotation of cutting and arc attack, athletes who combine attack and cutting usually choose anti-adhesive with better surface viscosity and slightly longer particles. In order to ensure good control of chopping and defense, sponges with moderate thickness (1.5-2.0 mm) and hardness (about 40 degrees) are often selected.

The core of the combination of attack and cut is "change"-rotation change, attack and cut change, hitting point change and rhythm change, so the selected racket should also fully reflect and adapt to this change. Many people choose rackets with different performances on both sides, for example, one side reflects the glue to change, rotate and attack actively, and the other side chooses to use an extremely thin sponge with a thickness of less than 0.8 mm with long glue, positive glue and raw glue; Some people also use anti-arc glue. Anti-arc glue is a soft sponge with low elasticity and non-stick surface, and its thickness is about 1.5 mm, which is used to control and change the chopping.

The substrate used in combination with attack and cut is usually larger, which makes cricketers softer and control the ball for longer. It is also beneficial for the hitting power under the stage to move the hitting center forward.

(5) Children athletes and beginners should pay attention to the following points when choosing rackets.

1. Because we are in the stage of learning technology, the type of play has not yet been determined, so we should choose a bad bat with light weight, good handle and slightly lower bounce, so as to master the ball control technology as soon as possible.

2. Children should choose a special racket suitable for their strength and quality development level and hand shape. In addition to light weight, it is more important that the handle is light and thin, which is conducive to helping them develop correct grip habits.

3. Children and beginners can choose a back rubber sponge with a thickness of 1.8mm and a hardness of about 40 degrees or a front rubber sponge with a hardness below 35 degrees. Children should try to choose regular rackets such as reverse glue or positive glue at the beginning, which is conducive to comprehensive learning of technology.

There are many different brands of sponges and rubber sheets on the market now. Imported brand-name products are exquisite, but there are also many high-quality products made in China. Usually, the anti-glue made in Japan has rough surface and fast delivery speed, which is suitable for the attack and anti-pull of fast loop ball; Domestic anti-adhesive surface is sticky, which is conducive to manufacturing rotation and more suitable for pulling out strong rotating loop balls with time difference. When choosing an anti-sticking agent, we should first look at whether it has passed ITTF certification. Secondly, it is necessary to observe the viscosity of the rubber surface and whether there are impurities.

There is still a certain gap between the quality stability of domestic sponges and imported brand-name products, but many manufacturers are constantly developing new products, and this gap is shortening day by day. When choosing a sponge, in addition to choosing its thickness and hardness, we should first observe whether its foaming is uniform, whether its thickness is consistent and whether its surface is smooth. Then put the sponge on a hard surface and press it with your fingers. A good sponge should feel soft and elastic when squeezed. Put the sponge in your hand and feel its yield and activity, then knead it into a ball and suddenly let it go. Observe the expansion speed of the sponge and the wrinkles on the surface of the sponge after expansion. The sponge that bounces up should have a light specific gravity and a fast expansion speed, and almost no wrinkles can be seen on the surface.
