Wet Father Answer: Not a quality problem!
After the oil filling and glue filling, after the sponge expands, the rubber surface is subjected to the tensile force of expansion, so that the particles under the rubber surface can be seen on the natural physical phenomenon on the rubber surface. We generally become a grainy rubber, or fish scale glue (small fish scales, large fish scales).
The picture above is the wild ride of a high-density hard sponge 3, and the sponge pores are very small and dense. Generally, this grainy feeling appears on the rubber surface, indicating that the oil filling and filling glue are more sufficient.
After filling with oil, the sponge expands and causes the glue to extend in all directions, and the rubber surface is pulled open, so that the particles below can be seen through the rubber surface.
We often see the rubber surface of some professional athletes, showing this grainy feeling, because they are filled with oil and irrigation more fully, and the sponge is pulled up. Professional athletes like to buy thin sponges with high degrees, such as the 2.1mm thick 41° Blue Country Madness.
ITTF stipulates that the thickness of sponge + rubber shall not exceed 4.0mm, and professional athletes have relatively high requirements for the support and elasticity of sponges, and the rubber with the choice of height can expand the sponge by filling oil in the later stage, and then brush the inorganic glue to form a layer of bottom layer to increase elasticity.
Amateur golfers generally rarely fill oil, most of them are still brushing organic glue, and the organic glue expansion effect can only last for a few hours at most, it is very difficult to pour out the granularity, and the probability of filling the granularity will be greater in the case of sufficient oil filling.
The picture above is the coat of the cake sponge, the coat is relatively large compared to the national coat, the toughness of the rubber surface will be relatively large, the cake sponge hole is relatively large, and the probability of graininess on the rubber surface after oil filling will be greater.
So, golfers, don't be surprised after the granularity is poured, indicating that you are fully irrigated, and the performance of this rubber can be 100% played out.
There are often amateur golfers who will ask this question and come up to question whether it is a fake or question whether you have a quality problem. To say that it is very tired, customer service explanation is useless, the customer does not believe at all, think you are arguing. Therefore, in the near future, I will collect the customer service of the table tennis network, and the various questions raised by the golfers encountered will be answered one by one, and I hope that the majority of amateur golfers can have a deeper understanding of table tennis equipment.
