The differences between the positive and negative glue of a table tennis bat are as follows:
1. Appearance:
The positive glue particles are outward, and the surface of the board is particles, which are in direct contact with the ball. The anti-adhesive particles face inward, and the surface of the board is smooth, which is in direct contact with the ball.
2. The dribbling function is different:
Most players like to use the forehand grip. Because the height of rubber particles is generally .8-1 mm, this kind of rubber not only has good stability, but also has great rebound force, which is easy to play the role of sponge and bottom plate and is conducive to improving the speed and strength of hitting the ball.
However, because the content of colloid is not very large, the particles are hard and lack of viscosity, the friction ability of the glue is far less than that of the reverse glue.
generally, the reverse glue is mainly a ball with a loop. This kind of rubber is soft and sticky, so it is not easy for the incoming ball to slide when it contacts the rubber surface, which is beneficial to increase the rotation of the ball.

Maintenance method of table tennis bat
The maintenance of table tennis bat can be simply summarized into three sentences: the bottom plate is protected from moisture, the rubber is protected from aging, and the use is protected from wrestling. The specific method is: after the racket is used, wipe the stains on the rubber surface with a special sponge, and stick a special ping-pong anti-adhesive protective film after the water dries. Positive glue should be collected after the leather surface is dry. When collecting rackets, they should be placed in a ventilated and dry place, away from heat sources, to avoid sun exposure, and not to pile up heavy objects on the rackets.
1. avoid being heated. The sponge and rubber of table tennis bat are easy to age after being heated, and their viscosity and elasticity are reduced, commonly known as "dead". The board is also easy to deform after being heated, which affects the accuracy of hitting the ball. At the same time, avoid the contact between the sponge and the rubber sheet with gasoline. Once it comes into contact with gasoline, the rubber products will be deformed and deteriorated.
2. Prevent rubbing, bumping and squeezing by abnormal external force. If you hit the ball in the right way, the racket won't knock against the table. When the racket is not in use, it is best to put it in a special racket sleeve, and at the same time put a flat plate made of wood or plastic in the racket sleeve to minimize the influence of external force on the racket.
3. Keep the racket surface clean. Once there is dirt on the rubber surface, the viscosity will be greatly reduced. At this point, the positive glue racket can be gently wiped with clean cloth and water. The racket with reverse glue should be wiped clean with a professional sponge every time after the ball is played. Care must be taken to avoid scratches on the surface of the rubber. After the racket is used, use a special sponge to wipe the stains on the rubber surface, and stick a special ping-pong reverse glue protective film after it is dried.
