How are table tennis balls made? How to make a table tennis racket that suits you?

The table tennis ball is made of two semi-circular balls, and a good table tennis ball is heated when it is glued, so there is a smell of plastic and glue inside.

So, what did the world's first table tennis look like? Who was the first to play this ball?

On our planet, there is a place called South America, which is the home of natural rubber. There are many rubber trees there, which cut the bark and shed milky white sap, which the local Indians called "the tears of the tree". They wait for the milk to solidify, rub it, and it becomes a small elastic ball.

Every night groups of Indians get together, sing, dance, and have a great time tossing around with this solid rubber ball.

In the 15th century, the explorer Christopher Columbus arrived here and was so curious that he brought the rubber ball back to Europe and presented it to the king of Spain. The people in the palace also thought it was fun to play with it. However, this kind of ball will become soft and unclean when exposed to a little heat.

So someone made a small plank and held it in his hand and slapped it. In this way, although the earliest table tennis balls and paddles existed, they had not yet entered the interior.

After a few more years, some aristocrats, in order to boast of their wealth, hired 54 craftsmen to carve table tennis balls out of ivory. This ivory ball is harder than rubber balls, and it is also elastic and does not deform. However, the cost is too high for ordinary people to afford.

The ivory ball makes a clattering sound when it hits the bat, which is very nice. So, it was hoped that a material would be found to replace ivory.

In 1893, the American Goodyear invented the rubber vulcanization technology, which improved the elasticity and solidity of rubber, so that the hollow ball was made. Hollow balls are fun, but lighter, and are often blown away by the wind when playing outdoors. Some people set up on the table indoors, two people facing each other and holding wooden planks to push them around.

This is probably the beginning of a sport like table tennis.

In 1869, the American Helit was hired by a company to study alternative materials for table tennis. He thought: too little rubber is taken from rubber trees, and ivory is expensive.

Can you use very cheap cotton? Helit treats cotton with chemicals such as alkali, and then reacts with nitric acid, camphor, etc., to finally make a new material called celluloid, or false ivory.

Celluloid is light and malleable. Just put this false ivory material in a mold and press it into two semi-round balls. Then use adhesive to close the ball blank, and after passing through the circular heat press, a small round table tennis ball is made.

Table tennis is afraid of high temperatures, squeezing, and open flames. It will soften and deform at 80 hours, so the flattened ping ball can be restored by soaking it in hot water at this temperature.

Although table tennis is small, it is fast, varied and technically demanding. In particular, the exercise of judgment requires athletes to be quick and grasp fleeting opportunities, which is very beneficial to cultivating the spirit of tenacious struggle. Therefore, table tennis has become a worldwide and universal sport.

Now, the ITTF has changed the use of orange balls in table tennis.

The table tennis ball is made of two semi-circular balls, and the table tennis ball is heated when it is glued, so there is a smell of plastic and glue inside.

Ten years of catastrophe personally. Do you feel happy when you are there? It doesn't matter here anymore、Are you okay with the sensory nerves of what you wanted!

Such a little bit of Jiangyan City? In this case, there will be a lot of surprises for us to come together! What you said is right, you have a lot of events, the Chinese team has added a scenic spot, the scenic spot is the Shennongjia Forest Area, one of the soldiers in the history of career development?

It's an urban way of life, and I don't know how to get it. In your house bears? I'm going to eat meat tonight.

Make a table tennis racket that suits you, choose a "DIY" racket, ball machine, glue, and glue, and then make your own bottom plate, according to your own style of play, style, buy materials from **** to tailor for yourself. For example, the "artifact" made by the grinding and infiltration of the pins is the "blue aromatic carbon" (seven splints) imitated by Stica, and its configuration is as follows:

Indonesian Ebony Fabric + Spruce Wood + Blue Aromatic Carbon + Paulownia Big Core + Blue Aromatic Carbon + Spruce Wood + Mahogany Core Surface.

Thickness: 8mm, the weight of the bottom travel leather plate is lost ridge: , the front cloud is a single rubber, and the reverse side is a common set of rubber, with a total weight of 165g. The handle is hollow and the handle is removed from the old Stika racket, and it looks beautiful!

Cost: Indonesian ebony surface material 10 yuan + spruce force material yuan + blue aromatic carbon 15 2 = 30 yuan + peach wood core surface material 5 yuan plus shipping (12 yuan) a total of 72 yuan (paulownia wood core is made of French Cabernet red wine packaging, no money).

Trial playing effect: moderate weight, sufficient bottom strength, fast speed off the board, transparent sense of hitting the ball (through the board), suitable for fast attack, arc circle play.

Making a pair of table tennis rackets requires a slow judgment of plates, racket handles, jigsaws, glue, sponges, rubber, and bottom plate edge protection. Homemade rackets can be roughly divided into three processes: equipment selection (baseplate, glue), pasting, and maintenance of the finished racket.

The first is to buy materials online, first, a board of cypress lifting section of large core board rice, (20 30cm) two, carbon fiber board centimeter) one, three, cypress veneer two, (20x35cm). Fourth, the table tennis racket handle is paid, and fifth, epoxy resin glue.

After the materials are purchased, the various plates are first lowered into the shape of ping-pong cypress (slightly larger). Stick the carbon fiber board first, apply the AB glue evenly on the large core board, put the carbon fiber board on the large core board and press it, stick it with two flat wooden boards up and down, and tighten the four corners with screws and wait for it to dry (1 hour dry) and then stick the other side in the same way.

After the two-sided carbon fiber board is glued, it should be noted that it is best to put plastic paper on it when sandwiched with a wooden board to prevent it from sticking to the wooden board. After all the sticking is finished, draw the line on the sample pat, grind the edge out with a grinder according to the line, be sure to grind it slowly, and paste it with white latex after grinding, and then use a grinder to grind the excess part out according to the handle after drying, and a table tennis bottom plate is done.

The table tennis table consists of several parts: a table, a net. As long as these conditions are met, you can base the rush and make a simple ball beating judgment table.

You can find a table that is long enough, or put two tables together to make a table; The net can be made up of a number of obstacles (provided that they are not easy to fall) that act as a block ball. Then it's time to complete a ping-pong table.
