What should I do if the table tennis racket rubber is spent

A widely used method for amateurs to self-configure quick-drying glue.

1) Tire repair glue Take water every day, about 1:4

2) Gasoline tire repair glue.

3) Cyclohexane tire repair glue.

4) Tire repair glue (raw rubber + benzene + methanol + water). Of course, the tire repair glue has not passed the ITTF certification, and it has slight toxicity, but it is cheap and sufficient, and a small can of 2 yuan (90ml) can be used about ten times. Judging from the effect of glue potting, as long as you use a large enough amount, there is such an incisive summary:

Either use butterflies, or use tire repair glue" - of course, the "butterfly" here refers to a variety of imported professional glue that can be bought, the former has a higher proportion of organic solvents, stronger volatility, and the effect of glue filling is obvious, but because the content of natural rubber is less, that is, the glue is less residue after brushing, and the adhesion is slightly worse, and the covering is easy to fall off after bonding.

5) Ethyl acetate + tire repair glue, after practice, the effect is good, and the tire repair rubber can be used to achieve the effect of fast glue.

In terms of actual use, considering health and performance, cyclohexane is currently the best solvent, with good effect and minimal toxicity, and can eliminate the trouble of removing residual glue. And Butterfly has a high-grade glue, Fair Chack, which uses cyclohexane as a solvent.

Professional glue is mainly composed of natural rubber and lipotic hydrocarbons (C7).

1) Pat Leo glue Beginners may wish to use "Pat Leo" brand glue, which is cheaper and the quality is OK.

2) Haifu glue is good, but it is too troublesome to remove glue.

3) Sanding brand non-toxic table tennis glue from the world's only table tennis professional glue production base - Belgium Lauster-Gmünt professional glue factory, green and non-toxic, can avoid a variety of diseases caused by long-term use of toxic glue, and maintain good health. Yes, it's just too expensive.

It is recommended that the landlord buy a special rubber cleaner to increase the viscosity of the rubber, and after cleaning, you can use a professional protective film to paste.

In fact, after playing, you can directly clean the surface of the racket with a small amount of water, and then paste the protective film.

It is recommended that the landlord, if you need to use the rubber for a long time, it is best to take care of it, do not tear off the rubber every time you play the ball, if you are not a professional player, there is no need to brush too many times when you are glued, which affects the life of the rubber, generally 2 times, three to four times of rubber. If the frequency of playing is not high, the rubber can be torn off after playing, and then stained before the next play, if it is frequent, it is best to dip it once every two weeks.

There are good and bad detergents, ranging from 30 to 70, not to mention those that are too advanced, the protective film is about 20, and the two tablets can be used for more than half a year.

The above personal advice.

Spend a few dollars to buy two pieces of rubber protective film (hard plastic paper is also available), clean the rubber after each game, and then paste the rubber protective film. This way, the rubber can be used for a long time.

It is recommended that you change the piece, don't feel sorry, the rubber that is spent, will give you a negative feeling when playing, causing a bad perception, once you get used to this feeling, then the action of playing will be deformed, see if you are willing to spend 300 yuan to buy the rubber to know that you are a table tennis lover, so don't be stingy with that piece of rubber, it is important to standardize the action.

Personally, I don't think it's troublesome, it's all about playing and sweating and wiping it directly, I don't remember the specific principle too clearly, probably some components in the sweat, which can recombine the chemical bonds of rubber and the like.

The only way to do this is to replace the rubber, but if you spend it, there is no viscosity, and you can't make a rotation that is too strong.

When the table tennis racket rubber is opened, you can use organic glue or inorganic glue, and generally organic glue is fine.

1. The main components of organic glue are rubber molecules and organic solvents, and the rubber molecules left after sol volatilization are cross-linked into polymers to play a role in adhesion. The proportion of organic solvents in the composition of glue is usually higher than that of rubber, and the commonly used organic solvents are cyclohexane, heptane, etc. This is also the current general glue, its market is much lower than inorganic glue, occupying a larger market.

2. The main ingredient of inorganic glue is inorganic binder, such as cyclohexane, which is often used now. The appearance of inorganic glue is colorless, tasteless, and clear as water. Inorganic glue is currently the most high, and high-grade sponges need to be used.

After applying the glue, stick it to the clean glass as soon as the glue is dry. Its purpose is to prevent the glue from volatilizing into the air and enhance the potting effect. It is colloquially known online as "Russian law".

This method is indeed more effective than ordinary methods, and it saves glue. At this time, the ball board is also coated with glue, and a thin layer is enough.

After more than ten minutes, you will find that the rubber gradually breaks away from the glass and warps. This is because the sponge expands and deforms. Try it with your hands, and if you don't stick to it, you can stick it to the bat.

Similarly, the glue on the ball board should also wait for it to dry and not stick to your hands, so that it can be glued firmly and not easy to degum.

Summary. When the rubber surface is not cleaned, its viscosity is greatly reduced, so it needs to be cleaned to maintain its stickiness. After each game, you can use a sponge dipped in water to clean the surface of the rubber, and apply a protective film when there are no water stains on the surface of the rubber.

Why is the newly bought rubber of the table tennis racket very sticky, and should it be treated?

Please wait patiently for 1-2 minutes, we are sorting out, and we will answer you immediately, and please do not end the consultation.

When the rubber surface is not cleaned, its viscosity is greatly reduced, so it needs to be cleaned to maintain its stickiness. After each game, you can use a sponge dipped in water to clean the surface of the rubber, and apply a protective film when there are no water stains on the surface of the rubber.

It is emphasized here that the rubber protective film should be attached, because the oxidation of the air and dust are also the main reasons for the loss of adhesive stickiness of the rubber. In this method, the adhesive recovery of the rubber is slightly slower, taking several hours.

If the racket is a high-end racket, it is recommended to use a professional cleaner, spray the cleaning liquid, and be sure to apply the protective film after wiping. The adhesive also recovers faster and causes minimal damage to the rubber.

In addition, the more sticky the rubber is, the better, because the stickiness is too strong, which will hinder the speed of the ball. Causes the power of the shot to decrease.
