نظرة عامةAbout Basketball Maintenance
how to maintain
1. It is not suitable to touch the water: Basketball is afraid of water. Daily care should be taken not to let the basketball directly touch the water and avoid playing in the rain. Prolonged contact with water will affect the normal life of the basketball, and it is easier to open the glue and affect the normal use
2. Avoid heavy pressure: do not kick or sit on the basketball, let alone press the basketball with heavy objects, so as not to cause deformation of the basketball, affect elasticity.
3. Reasonable inflation: Use a special air needle (need to be moistened) to insert slowly into the ball mouth. It is strictly forbidden to use a high-pressure air pump to inflate directly. The air pressure should be between 7-9 pounds; it cannot be over-inflated, otherwise it will easily cause the basketball to bulge and deform
4. Elasticity test: on a flat hard ground, drop the basketball freely from a height of 1.8 meters, the height of the first rebound should be 1.2 meters -1.4 meters is normal
5. Glue opening treatment: it is easy to open the glue due to water contact or other reasons, remember not to use 502 glue, 502 glue is Strong oxidizing glue will cause the surface of the basketball to oxidize and harden, which will affect the feel; please use a blending glue for bonding.
Wipe the surface clean before bonding.
