Carbamate vinegar shell layer additive 匕3 low> dish hardener, high temperature hardener and filler, low temperature hardener ruthenium or its ruthenium metal oxide. The material properties of the amino group (4) make the scrambled base (4) spherical shell layer 3 have high secret and high flexibility, so that the high swirling property (ie, high rotational frequency) of the batting ball can be effectively increased in the present embodiment. Since the low-temperature hardener and the high-temperature hardener have different reaction temperatures (for example, a difference of 30 degrees Celsius), the urethane spherical shell 3 can be formed in the center of the core layer and the second intermediate layer 2 A. The layer 1 is accurately positioned on the core (not shown), and when the temperature is raised to the reaction temperature of the high-temperature hardener, the arsenic spherical shell layer 3 is formed outside the second intermediate layer 2A, so that the core layer can be formed.丄, the first intermediate layer 2: the intermediate layer 2A and the geometric center of the urethane spherical shell layer 3 are identical, so that the Nalph sphere structure of the present invention has no eccentricity problem and has the advantages of good weight symmetry. Therefore, when hitting the ball, the axis directly receives the force from the swinging club head, and the force of inertia can generate additional force ^, which greatly improves the handling stability of the golf ball. In addition, different reaction temperatures may also cause the surface tension of the second intermediate layer 2 A to be extremely low, increasing the degree of adhesion between the second layer 2 A and the urethane spherical shell layer 3 /J6 w A 4253 ^ can reduce the energy loss of the amino f-acid spherical shell layer 3 to the core layer, which can improve the rebound performance and avoid the peeling phenomenon that often occurs when hitting the ball.

CA VIII, due to the high hardness of alumina powder, quartz powder or its I gold, the oxide can adjust the polymer hardness and polymer bomb of the urethane main material, so the amino phthalate ball can be The friction coefficient of the shell layer 3 is increased, and the edge of the urethane shell layer 3 is maintained. When the urethane shell layer is 3^ the same thickness, the friction coefficient is high and the edge is excellent. The higher the number of turns, the higher the rotational speed of the ball after hitting the ball, which makes the ball have high convolution, which makes the ball's flight direction stability higher. The better toughness makes the ball feel good, and can also take into account the feel of the hitting ball. And the controllability of the ball. ―In summary, since the core layer i of the golf ball of this creation is thicker and higher, the first intermediate layer 2, the second intermediate layer Μ = the record of return (c. aR) and the higher pressure purity, Therefore, the overall swirling of the ball can be reduced, so that the golf ball can fly farther; in addition, since the amino amic acid _ spherical shell layer 3 has an amino group m: the acid lanthanum layer 3 has a thin thickness, it still has Excellent properties (: early blade edge, south softness and high contact friction), the lion has a better initial light and a good long distance in the traditional golf ball to improve the performance of the golf ball.
