For artificial turf with a height of 50mm on a standard football field, the specification requirements for filling particles are as follows:
Youdaoplaceholder0 quartz sand filling standard
Filling capacity: 20-30kg/m² (as explicitly required by the new national standard GB-36246-2018)
Particle size: 0.3-1.5mm, silicon content ≥90%34
Function: Enhance stability, fix grass fibers and improve anti-slip property
Youdaoplaceholder0 rubber particle filling standard
Filling capacity: 4 to 7kg/m² (5 to 8kg/m² is recommended for international event venues)
Particle size: 1-3mm, must be environmentally friendly high-elasticity particles
Function: Provides shock absorption and cushioning, protecting athletes’ joints
Youdaoplaceholder0 precautions
- The filling depth should be 3/4 of the height of the grass filaments (approximately 36mm) to ensure performance balance 56; ,
- The particles should be evenly distributed to avoid excessive distribution which may cause drainage obstruction or a decrease in elasticity 12;
- For high-standard venues such as the Olympic Games, the DETX value should be ≥8800, and the filling volume must strictly match . 3.
- If it is a no-fill lawn (grass height 30mm), no particles are required, but the density must reach 21,000 tufts /m²7.
