The types of turf on the football ground
Artificial turf accounted for 95% of particles filled in the domestic, but many schools in the choice of products often tend to overlook the most important aspect of the construction, the construction technology of artificial turf grass in the late maintenance and is very important for improving the service life. Before the artificial grass is paved, the turf shall be checked for quality with the grass producing units, and the quality, density and knitting process of the sod shall be checked to meet the use requirements. A standard site can not be more than 30 points, while checking whether the quality of the filler to meet environmental requirements. In the process of laying, use special tools according to the specifications of lawn trimming, butt, lap will flush cutting the lawn. The joint shall be no more than 2 millimeters, using special glue for the artificial grass playground. Low temperature can not bond when the environment temperature should be selected within 10 DEG C construction is appropriate; other construction work should not be in the rain or rainy weather, otherwise it will lead to a long time even by non stick adhesive.
The natural grass and artificial turf football together is not a dream, now have such mixed lawn, the lawn is the natural structure of the grass root reinforcement, plastic, such as let the grass grow on the bottom of plastic net. In this way, the user-friendly nature of the natural lawn combines well with the superior durability of the football turf.
Because of the international advanced level, good sports performance and good practicability, the packed particle lawn has been accepted by the vast numbers of users in china. The materials used for the majority of polyethylene (PE) or polypropylene (PP) more than two kinds of polymer materials, the fiber is not filled with sand grass lawn, 2 - 3 mm below the surface of the backfill quartz sand and rubber particles. Its movement characteristics are very close to the natural lawn, and can be used all year round and all-weather. Usually, the lawn needs to be maintained for 6 to 8 months before it reaches its optimum state. This type of lawn is especially suitable for laying outdoors. Its service life is usually 5-8 years, but its actual life can be more than 5 years. In long dry weather, just by sprinkling a little water on the lawn, you can reduce the risk of scratching.
In the United States, artificial grass fiber materials most of the football field artificial turf is used for high-grade nylon material, also used multiple fibers, without filling sand artificial turf football field can be divided into two kinds of seepage and seepage. This lawn resembles the natural lawn in appearance, partly with a shock absorbing foam cushion layer, and the shock absorbing layer has a variety of density and thickness. Because in the domestic football really grasp the artificial turf technology manufacturers are not many, but mostly foreign technology, therefore, not filled with sand in the laying of artificial turf football field, especially the laying of shock absorbing foam cushion layer must be made by the foreign expert to complete. Shock absorption foam should be paved with a smooth asphalt as the foundation, the asphalt will be covered with gravel, sand and gravel as the basis, and the drainage system is the most critical link. In addition, the football field turf of this type in the installation process must use special mechanical artificial grass, especially in some professional sports venues or the high cost of laying installation is particularly important, otherwise the field leveling and uniformity requirements will not be reached, for example, for the 2008 Olympic Games hockey training venue of Beijing Lu City sports college hockey field and part in order to meet the special needs of movable pieces of artificial grass, artificial grass and other venues must be in strict accordance with the above requirements for construction.
