Roller skating venue is a special venue, which not only needs wear resistance and high hardness, but also needs to prevent side slip. Due to the high point-to-point compressive strength of the ground during roller skating, it is necessary to use polymer ceramic sand (special surface layer for roller skating venues), which not only has good anti-skid performance and meets the physical properties such as compression, bending and wear resistance, but also is 65,438+000% environmentally friendly and recognized by the International Roller Skating Federation. Never use emery, epoxy floor and acrylic paint again, which not only wastes costs, but also does great harm to athletes.
