The maintenance of table tennis rackets can be simply summarized in three sentences: the bottom plate prevents moisture, the rubber prevents aging, and use prevents falls. The specific method is: after using the racket, wipe the sweat stains on the racket with a dry towel. Use a wring-dried wet towel to wipe the dirt on the rubber surface. Cover the anti-glue with polyester paper before the leather surface is completely dry. It must be stored after the leather surface is dry. When storing the racket, it should be placed in a ventilated and dry place, away from heat sources, avoid sunlight exposure, and do not place heavy objects on the racket.

Rubber Maintenance

When you first learn to play, you will think that buying a good racket is the biggest investment, but as time goes by, you will know that the constant replacement of rubber will make it more durable. expensive. Therefore, how to maintain the rubber to extend its service life and how to determine when the rubber needs to be replaced have become the most concerned issues for golfers.

How long can a piece of rubber last? The answer ranges from 3 days to 3 years, depending on the amount of practice. Most top players need to change the rubber surface every 3 days to a week. But that's practicing five to eight hours a day and hitting every ball hard. If you are an ordinary practitioner, you can usually replace the rubber surface once every 1 to 3 months.

The biggest enemies of rubber are the sun and dust. Once the softer rubber surface on the inside is stained with dust or oil, the friction will weaken. People who practice more must use a soft cloth dampened with water to wipe out the dirt on the surface every two or three days. Placing rubber in a place with strong sunlight or next to a stove with a high temperature, or placed near a heater or air-conditioning outlet that blows out strong winds will also shorten its life. Therefore, the rubber must be placed in the racket box. The prepared rubber should be placed in a plastic bag to extend its service life.

The maintenance of rubber also has a lot to do with the weather. In winter, when the temperature is low, the rubber has poor elasticity; in summer or in areas with higher temperatures, the rubber has the best elasticity and tends to have strong friction, allowing the ball to fly far. In addition, when the humidity is high, there is moisture on the rubber, just like a layer of fog on the mirror. At this time, the ball is prone to slippery. During the rainy season, it is especially important to remove dirt from the rubber to avoid affecting the friction of the racket.

There are many types of rubber in table tennis tools, but they can generally be divided into two categories: reverse and front. Reverse stickers include reverse rubber and anti-arc rubber, and front stickers include positive rubber and raw rubber. Due to the different glue content, the anti-adhesive rubber has greater friction, adsorption on the surface, and strong adhesion. The rubber and the ball are not easy to slide when in contact, which is beneficial to increasing the rotation of the ball. In order to give full play to this feature, when using reverse glue, the most important thing is to keep the rubber clean. Do not wipe the rubber with oily hands. After each ball is played, the rubber can be rinsed with clean water and a protective film can be applied. If there is dirt that cannot be easily removed with clean water, you can also wash it with soap and other detergents and dry it before use.

According to rubber experts: Rubber molecules are entangled together like threads. After vulcanization, sulfur molecules and rubber molecules will be arranged in an orderly manner. The new anti-adhesive with good surface friction coefficient is mainly caused by the friction between the short ends and gaps of the linear molecular arrangement of the rubber against the ball. However, there are two main reasons why the anti-adhesive becomes non-stick. One is that dust and debris will The gaps between the anti-adhesive molecules are filled, causing physical changes to the anti-adhesive surface. Another reason is that the anti-adhesive molecules further react with chemicals in the air, causing chemical changes in the adhesive surface. According to the above principles, as long as you keep the playing environment clean and sanitary, and at the same time carefully protect your reverse rubber racket like the old American, the life of the reverse rubber racket will be longer.

After we choose a handy racket for practice, in order to avoid the discomfort caused by frequent replacement of the racket, unnecessary expenses, etc., we must maintain the racket well and use it rationally, and appropriately extend its life. Sports longevity is very important for people who want to play well.

A racket that complies with the rules and can be used in official matches consists of three parts: a base plate, a sponge, and a rubber. The following will introduce the precautions for their respective maintenance and use.

The popular trend of blades today is different from that of the 1960s, which is mainly reflected in two physical aspects. First, it is light in weight: current blades generally weigh between 90 and 100 grams; second, it is thin: in the 1960s, it was 6 to 7 mm, but now it is 5 to 6 mm. In order to pursue these two characteristics and maintain the good performance of "catching the ball, not shaking the hand, and having sufficient base strength", when selecting materials, it is necessary to use relatively light wood. During use, in addition to keeping the bottom plate in a dry place to prevent heavy pressure and breakage, special attention should be paid to the collision between the ball board and the table and the ground during the playing process. If you are feeding too many balls, you can use a spare board. When practicing, players who play the chipping style should keep a certain distance between their movements and the ground. They should also avoid the onset of bad habits such as being impatient to lose, deliberately dropping the racket, hitting the table with the racket, and hitting the backboard.

The main factors that affect the performance of sponges include thickness, hardness, elasticity, pore size, number of pores and other factors. Because the sponge is an expanding body, it cannot be pulled or pressed too much during use. When playing in a place with relatively low temperature, you must pay attention to proper insulation. The bottom temperature will affect the elasticity of the sponge. People who use a single piece of rubber and sponge board should use a fire-baked electric iron to fully melt the glue between the rubber and sponge when replacing the rubber to prevent damage to the sponge due to rubber replacement. Glue can foam the sponge and increase its elasticity, but when pasting it with the base plate, use non-toxic special glue, which can protect both the sponge and the base plate.

There are many types of rubber in table tennis tools, but they can generally be divided into two categories, one is reverse sticker and the other is front sticker. Reverse stickers include reverse rubber and anti-arc rubber, and front stickers include regular rubber, raw rubber and long rubber. Due to the different glue content, the anti-adhesive rubber has greater friction, adsorption on the surface, and strong adhesion. The contact point between the rubber and the ball is not easy to slide, which is beneficial to increasing the rotation of the ball. In order to give full play to this feature, when using reverse glue, the most important thing is to keep the rubber clean. Do not wipe the rubber with oily hands. After each game, you can rinse the rubber with clean water and put a plastic film on it. If there is dirt that is difficult to remove with clean water, you can also wash it with soap and other detergents, dry it before use.

The rubber content of the front-facing rubber is low, the tooth grain hardness is large, and the friction is small. The rubber and the ball are in contact with each other, and the area is small, making it easy to slide. Based on this characteristic, when using positive glue, special attention should be paid to keeping the rubber dry. If you play in a humid place, you can use a desiccant to wipe the rubber to reduce the humidity on the rubber surface. The backing of the front-facing rubber is generally thin. When pasting it with a sponge, do not apply too much glue to the rubber at one time to prevent unnecessary loss due to "rolling" of the rubber.
