About artificial sports turf filling materials
With the development of the sports industry, the increasing integration of sports and education in schools, and the strengthening of people’s awareness of fitness, artificial turf sports fields have become one of the basic hardware for sports venues, sports parks, universities, middle schools, and even kindergartens. So how to create a high-quality artificial turf sports field? The quality of the site is not only related to the basic requirements such as the quality of the artificial turf itself, site slope, flatness, drainage, etc. but also has an inseparable relationship with the filling materials. In terms of site elasticity, friction, sports comfort, etc., the filling of accessories plays a crucial role.
Artificial turf-filling accessories generally refer to rubber particles and quartz sand. Accessories are the key elements of the artificial turf system. Its existence makes the establishment of system properties inevitable. At present, the most common practice in the world is to fill quartz sand and rubber particles, first filling the quartz sand, and then filling it with rubber particles.
According to the test report of FIFA, quartz sand is called stability infill, which is stability filler. Quartz sand is made of quartz and is mostly produced by washing and drying technology. It has the characteristics of high hardness, large specific gravity, uniform particle size, and small edges and corners. Since the artificial turf used in sports fields such as football fields is 40-60mm, the grass cannot be completely erected. Filling the quartz sand can not only stabilize the roots of the artificial turf grass but also make each artificial grass stand upright; The turf can also be weighted to effectively hold the turf in place without shifting. Rubber particles are performance infills, which are performance fillers, as the name suggests, ensure their sports performance. The artificial turf itself also has a certain thickness and elasticity, but in order to meet the needs of sports and to be closer to the sports effect of natural grass, it needs to be further filled with rubber particles to increase elasticity and absorb shock to prevent athletes from getting injured. The rubber particles are elastic. After filling, the rebound of the field can be better, which can minimize sports injuries and increase sports comfort. Sometimes in order to further achieve cushioning, another layer of cushioning pad is needed under the lawn. Of course, the specific filling amount should be calculated according to the needs of the site.
