How long can the table tennis racket last?
The service life of table tennis bat is not necessarily, it depends on maintenance. A well-maintained racket can be used for a long time. If you don't take care of the racket, its life will be shortened.

Maintenance of table tennis racket

The maintenance of table tennis bat can be simply summarized as three sentences: the bottom plate is moisture-proof, the rubber is anti-aging and the use is anti-falling. The specific methods are as follows: wipe the sweat stains on the racket with a dry towel after use, wipe the dirt on the leather with a wringing wet towel, cover the leather with polyester paper before it is completely dried, and collect the positive glue after the leather is dried. When collecting rackets, put them in a ventilated and dry place, away from heat sources, and avoid exposure to sunlight. Do not pile up heavy objects on the rackets.

1 Avoid heating. Sponges and rubber of table tennis bats are easy to age after being heated, and their viscosity and elasticity are reduced, commonly known as "death". The board is also easy to deform after being heated, which affects the accuracy of hitting the ball. At the same time, avoid contact between sponge and rubber sheet and gasoline. Rubber products will be deformed and deteriorated once they come into contact with gasoline, so special attention should be paid to it. Because sponge is an expanding body, it should not be excessively pulled and stressed during use. When playing in a low temperature place, you should pay attention to proper heat preservation, because the bottom temperature will affect the elasticity of the sponge. People who use a single piece of rubber sheet and sponge sheet should use a fire-roasting electric perm head to iron the rubber sheet when replacing the rubber sheet, so that the glue between the rubber sheet and sponge can be fully dissolved and the sponge can be prevented from being damaged when replacing the rubber sheet. Glue can make the sponge foam and increase its elasticity, but when sticking to the bottom plate, use non-toxic special glue, which can protect both the sponge and the bottom plate.

2. Prevent friction, impact and extrusion caused by abnormal external forces. If you hit the ball correctly, the racket won't hit the table. When the racket is not in use, it is best to put it in a special racket case, and at the same time put a flat plate made of wood or plastic in the racket case 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, you can gently wipe the glue racket with a clean cloth and water. Wipe the ball with a soft cloth after the anti-adhesive racket has finished playing. Be sure to avoid scratching the rubber surface, and finally stick a layer of nylon paper or a thin soft plastic sheet on the surface. Usually, my specific methods of maintaining table tennis rackets are: wiping the sweat stains on the rackets with a dry towel or tackifier, wiping the dirt on the leather with a wringing wet towel, covering the leather with polyester paper before the leather is completely dried, and collecting positive glue after the leather is dried. When collecting rackets, put them in a ventilated and dry place, away from heat sources, and avoid exposure to sunlight. Do not pile up heavy objects on the rackets. In table tennis tools, there are many kinds of rubber covers, but they can be roughly divided into two categories, one is reverse stickers and the other is positive stickers. Reverse stickers include reverse glue and arc-proof glue, while front stickers include positive glue, raw glue and long glue. Because of the different rubber content, the reverse rubber has large friction, strong surface adsorption and adhesion, and the contact point between rubber and ball is not easy to slide, which is beneficial to increase the rotation of ball. In order to give full play to this characteristic, the most important thing when using reverse glue is to keep the rubber clean. Don't rub the eraser with greasy hands. After playing the ball every time, you can rinse the rubber with clear water and paste a layer of plastic film. If there is dirt that is difficult to remove with clean water, it can also be cleaned with detergents such as soap and dried before use.

The front rubber is low in rubber content, high in tooth hardness, low in friction, small in area and easy to slide because the rubber is in contact with the ball. Based on this feature, special attention should be paid to keeping the rubber dry when using positive glue. If you play in a wet place, you can wipe the rubber with a desiccant to reduce the humidity on the rubber surface. Generally speaking, the bottom skin of rubber is very thin. When using a sponge, don't apply too much glue to the rubber at a time to prevent the rubber from being "rolled" and causing unnecessary losses.
