But who has bought nearly 1000 yuan of basketball? I didn't even think about it ...
So nonsense, the most basic rule for buyers to use basketball is that they can afford it. ...
Anyway, there are two kinds of basketball, indoor and outdoor.
The difference before is to look at the rubber width between two rubber skins. The wide one is indoor and the narrow one is outdoor. The most obvious feeling is that the outdoor racket is high and elastic, while the indoor racket must be inflated, otherwise it will not be shot. This is because the elasticity of wood floor is much greater than that of cement or asphalt.
So far, outdoor balls used in the past have been rare. Maybe these balls should be labeled as the 20th century and displayed on the shelves in the museum. At present, the difference between indoor balls and outdoor balls should be: more outdoor balls with concave-convex particles, hard leather and relatively low price are used. This kind of ball feels ordinary, but because of the deep particles, it can have a good friction coefficient even if it is stained with dust, but the concave and convex particles will be gradually ground down. At that time, the ball skin will be as smooth as smooth kraft paper. If the ball is of good quality, it will not shrink or deform, but will become a chicken rib. Eating is tasteless, but it's a pity to throw it away ... indoor balls are completely different. They are specially used to clean indoor venues. The skin of the ball is very flat. When clean, the friction coefficient is very large, and it feels a little sticky. My hand is only 1.75 meters high. But I can not only catch the indoor ball easily with one hand, but even catch it directly with one hand during the racket ... but only when there is no dust can I hit it twice in the ordinary outdoor court, let alone catch it easily. There may be no outdoor ball sliding with concave and convex particles, and there is no outdoor ball wear resistance ... but as long as it is indoors or in a clean outdoor venue, the feel of this ball is much better than that of the outdoor hard ball, and the texture of the ball skin is very good. It can not only reduce the possibility of finger prick, but also avoid the feeling of losing control when shooting. From the beginning of the action until the basketball leaves the fingertips, it is under precise control, and some cheap basketballs have long been out of control before that, so they have to be pushed out casually when their hands slip ... In recent years, many people have bought basketballs below Spalding 150 yuan, and I have also used a few, which are very general and feel heavy. It needs a lot of inflation. It may be a more orthodox indoor dance. After playing for several years, some of Spalding's cheap balls have blossomed, but overall, the quality is much better than other brands, but don't expect too much. Personally, I feel that this kind of ball is much worse than Spalding played in training camp before. I think star brand 4 series basketball is the most suitable for home use. Although the quality is not as good as Spalding's, it's sticky.
The cheapest 487 series is around 80 yuan, but the quality is too poor. Generally, it only takes one year, and the most comfortable layer on the ball cover is polished, which is not cost-effective. Other 467; 497; 4 1 17, etc. Although the feel is not much different before use, the service life is much longer. You can choose these balls according to different economic conditions. In addition, please remind me that most models of STAR are relatively light, so please try to choose a heavier model.
It is not recommended to buy other types of basketball unless the stadium where you usually play is very dusty.
First, the structure of basketball:
To buy high-quality basketball, it is necessary to understand the structure of basketball:
1, liner: that is, the bladder, that is, the heart of basketball, is made of black rubber at the innermost layer of basketball;
2. Wire winding: The middle and high-grade basketball must be evenly wound on the surface of the ball liner with nylon wire special for basketball, so that the ball liner forms a cocoon-like protective layer, but not every kind of basketball adopts this process, and many low-grade basketball does not wrap the wire, but uses gauze instead;
3. Intermediate bladder: the supporting structure between the inner bladder and the epidermis is made of rubber;
4. Skin: divided into three categories: rubber, synthetic leather (superfine strong fiber, PU, PVC, etc. ) and dermis;
5, the ball mouth: the "throat" of basketball inflation is very important for air tightness.
Second, what are the advantages of high-quality basketball?
1, lining: brands like Sanying and CBA all use imported rubber, which is the same as the lining of high-end automobile tires. After strict patented technology processing, the bounce is soft and stable, which is the internal source of the delicate feel of high-quality basketball. A good feel will certainly bring good confidence.
2. Winding: Sanying, CBA brand basketball only uses nylon thread special for basketball with very good flexibility, and it is evenly wound with a precise special winding machine for basketball for 2 kilometers, which makes the basketball bounce more textured, the ball flies more stably and accurately when shooting, and the basketball is more firm and not deformed;
3. Leather: High-quality basketball is made of leather specially made by professional manufacturers, which can meet the requirements of different venues and the feel habits of customers. Sanying Basketball and CBA brand basketball provide a variety of basketball series with different materials for basketball lovers to choose from.
Third, how to distinguish all kinds of basketball
1, look for the trademark of brand basketball;
2, check the overall production process;
3, check the bounce, perimeter, center of rotation, ball technology and comprehensive feel, etc.
4. Check whether the free pin and bag are complete;
5. Check whether the printing and number of the certificate are consistent with the bar code on the sphere;
6. Check whether the retailer has the designated dealer certificate issued by the brand basketball manufacturer, and both Sanying Basketball and CBA brand basketball have specially made designated dealer certificates;
7. If you are not sure of the authenticity, you can call the manufacturer directly.
Fourth, how to use basketball correctly
Buy a good quality basketball, but also pay attention to the use of:
1, the basketball pressure should be 7-9 kg, otherwise it is easy to deform. Test method: on the flat and hard ground, let the basketball fall freely from the height of 180CM, and the rebound height is 125- 145 cm, which is normal;
2. Pay attention to choose indoor/outdoor basketball with different material series according to different venues;
3. After use, clean the surface of the ball (leather basketball should not be wiped with wet cloth to prevent mildew) and store it in a cool and dry place.
