The filling depth of the auxiliary materials of artificial turf depends on the height of the turf

Selection criteria of rubber particles: 1. Select environmentally friendly elastic rubber particles with dense rubber particles and high rubber content. According to the new national standard, the high polymer content is not less than 20%; 2. The particle size of the rubber particles is 1-3mm, which is a Triangular rhombus or regular shape; 3. Good particle material has good elasticity, is clean, and has no dust, the production process is shear type or extrusion type, with no oily rubber particles.

The filling depth of the auxiliary materials of artificial turf depends on the height of the turf and the performance required by the field. Generally, the height of the football field turf is between 40-60mm. According to the 50mm grass height used by the FIFA football field standard, the height of the filling materials is 3/4, that is, 36mm (about ±1mm), which is in line with the elasticity of the field to the football and the hardness of the surface. If it is a sports field of primary and secondary schools, accessories can be added appropriately, and it can even be equal to the grass silk. Therefore, not all sites have the same depth of filling materials, and they are filled proportionally according to different sites and grass silk heights.

The filling ratio of artificial turf accessories needs to be filled according to different types of sites. For sports with high impact strength, such as football fields, rugby fields, etc., the reference ratio of filling quartz sand and rubber particles is 40% quartz sand and 60% rubber particles, which can increase the cushioning performance of the court and reduce the sports injury of players. For sports fields with relatively small impact strength, such as tennis courts, gate courts, etc., the filling ratio can be reduced accordingly, and the field can be kept flat.
