First, the structure of basketball: in order to buy high-quality basketball, we need to know the structure of basketball: 1, liner: the liner is the heart of basketball, and it is made of black rubber in 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 is good about high-quality basketball: 1, inner liner: brands like Sanying and CBA all use imported rubber, which is the same as the inner liner material 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 and identify 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 a designated dealer certificate issued by the brand basketball manufacturer, and Sanying Basketball and CBA brand basketball have a specially made designated dealer certificate; 7. If you are not sure of the authenticity, you can call the manufacturer directly.
Maintenance:
1, choose the site
According to different sites, you need to choose different field earths. There are two choices: outdoor ball or indoor ball. General wooden floor, plastic floor, water mill and other smooth venues choose indoor balls, that is, basketball with more PU components; Outdoor basketball chooses cement field, street basketball field and mud field.
2. Basketball is afraid of water
No matter what material, brand and model of basketball, they are afraid of water. Usually, you should be careful not to let the basketball get wet or play in the rain. Otherwise, it will shorten the life of basketball, but it will leave internal injuries and soon finish the life course. In addition, wet basketball is easier to stick;
3, regular inspection
Basketball needs regular inspection, mainly to determine its inflation saturation, not too saturated or too peaceful. The most intuitive inspection method is: lift the basketball straight to the top of your head, gently put it on the ground and bounce it to your chest, indicating proper inflation; If it bounces to the front, it means that the inflation is too full; On the contrary, it means that the gas is insufficient.
4. Don't make balls
Don't sit on the basketball when you don't play or rest, and don't press it with heavy objects, otherwise it will be easy to deform. A good basketball, if not round, may not be too far from the court.
5. Don't be exposed to the sun.
When basketball is not in use, put it in a cool and dry place, not in sunny places such as balcony. Exposure to the sun is easy to oxidize the basketball skin and explode the liner.
6. Basketball storage
The storage environment of basketball is very particular, and it can't be placed in a high temperature and humidity place. For example: bask in the closed trunk. After use, it is best not to wash the basketball with water, but to wipe it with a dry cloth.
7, pay attention to cheer up
The skills of air suction mainly include: first wet the ball needle with oil or water, and then gently insert it into the bladder. Be sure to inflate it with a ball needle. If only the inflatable nozzle is used, the skin will be separated from the lining. Be careful not to let saliva touch the end of the air needle when inflating the basketball, because there are ingredients in saliva that can digest rubber, which will corrode the air nozzle and lead to slow exhaust. It is best to immerse the end of the air needle in cold water and then insert the air nozzle to inflate.
8, glue processing
Sometimes, the edge of basketball will be stuck because of watering or weak adhesion. Don't be afraid, it's just a small problem. But remember, never use 502 to remove glue. 502 is a strong oxidizing glue. After bonding, the leather in that place will be oxidized and hard, which will affect the feel. In this case, take it directly to the shoe repair place and ask him to help you glue it with mixed glue. It doesn't matter. Wipe the wound before bonding.
