How to identify the quality of basketball

Choosing table tennis: When purchasing, you should master the following four essentials:

Appearance: The surface of the ball must be fine and non-reflective, and the waist seam of the ball must be neat and crisp.

Bounce Height: The ** height of throwing the ball from a height of 305mm onto a standard table tennis table is between 235mm and 255mm. If the bounce of the ball is high or low, it means that the elasticity of the ball is uneven.

Roundness: Place the ping pong ball on a smooth, flat surface and rotate to see if there is any vigor**. It means that the roundness of the ball is not good, the stability of the ball is poor, and the landing point of the ball is not easy to control.

Hardness: Pinch the pre-part of the ball with your thumb and index finger to observe whether the softness and hardness on both sides are consistent. If the degree of ** is the same, it means that the hardness quality of the ball is better, and the performance is better. First, **, depending on your financial situation and how much you love basketball.

Second, the brand, the key to miscellaneous brands is to be unhappy, and the quality of the good brand workmanship is really good, I recommend buying butterflies reliable, third, buy online to buy rest assured, it is best to find a company with a physical store**, I have bought two Spalding basketballs on the Internet, mine was bought in a store called Yunjie Sports on the last day, it is a **business of Spalding manufacturers in Hefei, it is recommended that you go to see,**I don't remember, you can find it in **Soyunjie Sports to see if you can find it, for reference only.

Distinguishing the quality of basketball is mainly from the following aspects:

1。Liner, of course, you can't cut the basketball to see inside, but you can try its bounce soft and stable by slapping the basketball, and the basketball with a good liner puts the ball on the chest and falls vertically, and the height of each ** is the same.

2。Yarn wrapping, good yarn wrapping can make the bouncing of the basketball textured, the ball flight and rotation are stable and accurate when shooting, and it will make the ball firm and not easy to deform. The judging method is to press the basketball repeatedly with both hands, if it feels solid and rebounds strongly, it proves that the yarn is better.

3。Epidermis, a good epidermis should have the advantages of anti-slip, wear-resistant, sweat-absorbing, etc., and the test of anti-slip can directly feel whether the ball has a feeling of touching your hands. For the abrasion resistance test, you can use your fingernails to scrape the surface of the basketball, if there are obvious scratches, the epidermis is less abrasion resistant.

As for sweat absorption, wipe the surface of the basketball with a damp cloth, if it becomes dry sooner, it proves that sweat absorption is better.

4。Feel, feel this thing is not very easy to say, experts can feel good or bad in the hand, if you don't have experience in this area, please pay more attention to compare the weight of the basketball, and whether the texture is standardized, consistent.

Generally speaking, the real version of basketball has a fake. I just want to be a spordin. But I like the STAR brand. I've been playing for two years, and I put the ball outside the house on winter, summer, rainy and sunny days, and I didn't say that there was a bulging phenomenon, so I took it.

Let me tell my friends, people who play basketball don't care about whether the basketball is real or not, they only care about how it feels in their hands. That's all that matters. When I buy balls, I take some balls and I know which one to buy, and the one I buy is definitely the most expensive. -

1.Look at the logo on the tongue of the shoe.

2.Try on. Look at the hardness and softness of the sole.

Here's how to identify good or bad basketball:

1. Look at the surface of the basketball: There are no flaws on the surface of a good basketball.

2. The smell of basketball: The surface of a good basketball has a fragrant leather smell, and the surface of a bad basketball is a rubber smell.

3. Press the basketball: a good basketball, the surface of the basketball can't be pressed, on the contrary, the bad basketball is a pit.

4. Basketball weight: Basketballs that are too light or too heavy are not good.

5. Basketball elasticity: Let the basketball fall vertically from the top of the head, a good basketball bounce should be straight, no oblique jump, and the landing should stop in place, rather than rolling away.

In fact, the quality of basketball can be tested, and it can give you some standard data of basketball, but it is difficult for you to apply it practically. When picking a basketball, you can use the following steps: take a look: there are no flaws on the surface, and sometimes the brand-name ball bought in the supermarket is only.

Forty or fifty yuan a piece, often with surface flaws, although it does not affect the use, but it is best for personal use, and it is not appropriate to give it away. Second smell: good materials have a fragrant leather smell, and bad ones are rubber smells; Triple press:

The good ball, the lack of gas can not be pressed, on the contrary, the bad ball is full of gas, and a pit is pressed; Fourth: Balls that are too light and heavy are not good, but ordinary people can't pick them up, and they must be known by people who play often; Five bullets: let the ball fall freely from the top of the head, see if the bounce is straight, whether there is an oblique jump, on flat ground, should fall several times and then stop in place instead of rolling away.

The height is not on the waist and under the chest. P.S. The part of the basketball rules about "basketball".

3. The material, size and weight of the ball 1. The ball is round and is an approved dark orange; 2. The shell is made of leather, glue or synthetic substance; 3. The circumference shall not be less than meters (cm) and shall not be greater than meters (7 8 cm); 4. The weight shall not be less than 567 grams and shall not be more than 650 grams; 5. After inflation, make the ball fall from the height of meters (measured from the bottom of the ball) to the ground of the court, and the height of the ball shall not be lower than meters, nor higher than 0 meters (measured from the top of the ball); 6. The width of the seam or groove of the spherical surface shall not exceed meters (mm).

Resources.

The feel, the good quality ball feels very comfortable. Generally, you can look at the ball on the Internet to compare it, the kind of consumption that suits you. Then memorize the name of the ball and go to your local sporting goods store to buy it. It's Spalding in general, and I don't have much research on the rest.

A good basketball has a lot of friction on the surface, and such a basketball feels good, on the contrary, a basketball with a smooth surface is not good, and it is easy to get out of the ball.

2.Weigh the weight of the basketball.

A good basketball is a little heavier, but it doesn't feel heavy in your hand; Worse basketballs are lighter, and throwing the ball will feel light. Therefore, when buying, you should choose a heavier basketball.

Before buying a basketball, you should carefully check whether the number on the certificate matches the barcode on the ball, many inferior basketball certificates are forged and do not match the code on the ball, so you should pay special attention.

Question: How to distinguish between a basketball** and a fake?

It's the feel, the quality of the basketball When your hand touches the basketball, you know that the ball doesn't belong to you.

Feel, elasticity, glue line

Look at the leather, it's not easy to get packed

1. The structure of basketball: To buy a high-quality basketball, it is necessary to understand the structure of basketball. 1. Liner:

That is, the ball gall, which is the heart of the basketball, is in the innermost layer of the basketball, made of black rubber; 2. Winding silk: Medium and high-end basketballs must be evenly wound with a basketball-specific nylon wire on the surface of the inner tank of the ball to form a protective layer like a cocoon on the ball, but not every kind of basketball adopts this process, many low-grade basketballs are not wrapped with silk, but replaced by gauze; 3. Middle tank: the supporting structure between the inner tank and the epidermis, made of rubber; 4. Epidermis:

It is divided into three categories: rubber, synthetic leather (ultra-fine strong fiber, PU, PVC, etc.) and genuine leather; 5. Ball mouth: the inflatable "throat" of basketball, which is very important for air tightness. Second, high-quality basketball is good in ** 1, the liner:

Like Sanying, CBA brands are made of imported rubber, which is the same material as the high-end car tire liner, processed through strict patented technology, soft and stable bounce, is the inner ** of high-quality basketball delicate feel, and a good feel will of course bring good self-confidence; 2. Filament: Sanying and CBA brand basketballs only use special nylon filaments for basketball with very good flexibility, and use precision special basketball winding machines to wind them evenly, with a length of up to 2 kilometers, so that the bounce of the basketball is more textured, and the flight and rotation of the ball are more stable and accurate when shooting, and the basketball is stronger and not deformed; 3. Skin: high-quality basketballs are made of leather exclusively supplied by professional manufacturers, which can meet the requirements of different venues and the feel habits of customers.

3. How to identify all kinds of basketball 1. Identify the trademark of brand basketball; 2. Check the overall production process; 3. Check the bounce, circumference, rotation center, ball nozzle process and comprehensive feel, etc.; 4. Check whether the free ball needles and bags are complete; 5. Check whether the printing and number of the certificate are consistent with the barcode on the sphere; 6. Check whether the retailer has a designated distribution certificate issued by the brand basketball manufacturer, and Sanying Basketball and CBA brand basketball have specially made designated dealer certificates; 7. If you can't determine the authenticity, you can call the manufacturer directly. After buying a good quality basketball, you should also pay attention to the use method: 1. The air pressure of the basketball should be 7 9 pounds, otherwise it is easy to deform.

Test method: on a flat hard ground, let the basketball fall freely from a height of 180cm, ** height is normal at 125 145cm; 2. Pay attention to the selection of indoor and outdoor basketballs of different materials according to different venues; 3. After use, clean the surface of the ball (do not wipe the leather basketball with a damp cloth to prevent mold), and store it in a cool and dry place.

Fake basketball shouldn't be so fast, it means that you use too much strength.

Spalding, a good basketball, the outermost layer is very soft, but the inner layer is very hard, but the really good ball is generally indoors, and the outdoor ball is not long long. It is enough to buy a more than 100 point, but it is more useful than the more expensive indoor ball.

I think the first is branding. The best brand in global basketball is Spalding. Now**Spalding** is already very civilian, and you can buy a lot of Spotding's basketballs for 236 yuan. The cheapest price on the Internet is 236. I'm afraid the others are fake.

It is estimated that there will not be much difference in the rest of the country. Of course, there are some other basketballs that are good, but they are all more expensive. There are almost no more professional brands, except for Spalding, the common brands are Locomotive, Nike, Shanghai Lanhua, etc.

However, these brands are far behind Spalding. Now 9 out of 10 basketball enthusiasts use Spalding.

Domestic I think the kind of 75 yuan locomotive you mentioned is OK.

I also use but the counterfeit Spalding is more expensive than the genuine locomotive.

I don't know why.

Counterfeit 160 or more.

Second, texture. Generally speaking, the leather used in a good basketball directly determines what we usually call the feel of play. The texture of a good basketball should be touched, a little sticky and elastic. No slippage.

Third, energy efficiency. A good basketball is played at full capacity. You can see how well it performs by throwing the ball. Generally speaking, if you lift the ball to the back of the meter, if the ball bounces off the ground for the first time and then returns to the meter, it proves that the ball is bouncing well.

Generally speaking, a ball that meets the above three characteristics is considered a good basketball.

And then tell you how to tell the real from the fake Spalding basketball?

1. Scratch off the 16-digit unique certification code on the product certificate, send a mobile phone text message or log in** for certification. (The product certificate with the certification code will be used from August 2004 onwards).

2. Look for the spherical Spalding trademark.

3. Check the overall production process.

4. Check the bounce, circumference, rotation center, ball nozzle process and comprehensive feel, etc.

Classmates, you shouldn't be greedy for cheap when buying basketball, it is recommended that you buy Spalding's basketball - NBA exclusive, and the quality of the feel is ***.

**150 or more is basically OK, go to a bigger mall to buy, ***. I bought a 140 Spalding basketball a long time ago, and I have been playing for 3 years, and there are no quality problems so far.

Pay attention to the authenticity of the basketball, come with a counterfeit card with the ball, scratch off the coating, dial the service**, enter the anti-counterfeiting code, you can distinguish the authenticity.

Hope it helps.
