Original title: Main factors to be considered when constructing artificial turf by Henan artificial turf manufacturers
In recent years, natural turf has been gradually replaced by artificial turf due to the disadvantages of large investment, difficult maintenance, and large seasonal influence.
Artificial turf is an artificial turf made with plastic chemical fiber products as raw materials. Compared with natural turf, the advantages of artificial turf reuse, etc., are irreplaceable for natural turf. Therefore, artificial turf is very suitable for the high frequency of use in primary and middle school sports grounds or various training grounds.
Before artificial turf is constructed, the following factors should be mainly considered:
The first is the choice of the type of artificial turf. The turf surface can be divided into two types: mosaic type and woven type. The woven lawn is woven with nylon, and the finished product becomes a blanket. Compared with inlaid tufted lawns, weaving artificial turf has a complicated production process and a relatively high price. The surface hardness of the lawn is large and the cushioning performance is not good. However, the lawn has good uniformity, strong and durable, and is very suitable for tennis, hockey, and lawn bowling. Waiting for movement. Compared with woven lawns, inlaid lawns have longer leaf-like fibers with greater variation, ranging from 12 to 55 mm, and can be adjusted according to special needs. The grass is filled with quartz sand, rubber granules or a mixture of the two, and its appearance and properties are similar to those of natural lawns. It can be installed indoors and outdoors. It is suitable for football, rugby, baseball, etc.
The second is the production materials and selection of artificial turf, generally there are two types: polypropylene (Pol-ypropylene, PP) and polyethylene (Polyethylene, PE). The artificial turf made of PP material is solid and has a small cushioning force. It is generally suitable for sports with low impact, such as tennis. The artificial turf of PE material has soft texture, good cushioning performance, less damage to athletes, and is suitable for sports with greater impact, such as football and rugby. It is also possible to mix the two materials to make artificial turf, so that the advantages of the two can be combined to meet the needs of special competitions. For some high-intensity sports competitions, in order to improve the quality of the competition and minimize the injuries of the athletes, when constructing artificial turf, generally choose a relatively high fiber material, usually 25-50 mm, and choose PE artificial turf or Artificial turf made of PE/PP mixed materials. To construct an artificial turf sports field, when choosing the height of the artificial turf, generally consider the overall budget of the stadium. The artificial turf with a relatively high height has relatively high construction and maintenance costs.
Furthermore, the choice of filling materials for artificial turf, generally sand or rubber particles, sometimes a mixture of the two. When mixing, the ratio of the two depends on the specific situation. The usual mixing ratio is 70% rubber particles + 30% sand. In the past, 100% sand was used as a filling material in order to increase the stability of the base of the lawn. However, with the maturity of the artificial turf manufacturing process, the basic manufacturing has been relatively perfect, so in the past, sand was used to stabilize the lawn. It has been gradually eliminated, and now 100% rubber particles are used more filling methods. The filled sand or rubber particles are mostly medium in size, and they must be washed before filling. For some sports with high impact strength, such as rugby and football, the proportion of rubber particles should be appropriately increased to minimize athletes’ injuries. For those sports venues with low impact strength or almost no impact, such as tennis courts, as long as the hardness of the venue is uniform, the requirements for cushioning are not high. Therefore, there is more room for the choice of filling materials.
There is also the depth of filling. The filling depth of quartz sand or rubber particles in the artificial turf can be determined according to the purpose of use and the selected turf height. For sports with greater impact strength, artificial turf with longer leaf bundles and deeper fillings can be selected. Generally, the suitable filling depth of artificial football field turf is 5 mm from the tip of the blade; and for the requirements of high flatness and uniformity For good sports such as hockey, the leaf bundle can be appropriately lowered, the filling depth can be increased, and it can even be level with the lawn surface. According to research, the rebound of the football and the hardness of the surface of the artificial football field can be controlled by the type of filling and the depth of filling to some extent.
Finally, some artificial turf is designed with a drainage system, the lawn cushion is permeable, and the base layer is designed with drainage pipes. The construction structure of this type of lawn is more complicated and the cost is higher. However, some systems do not have a drainage system designed, so they have to rely on the natural slope of the surface for drainage, so the surface construction requirements are higher.
It can be used around the clock and is less affected by rain and snow. It is easy to maintain and has low maintenance costs. The material is environmentally friendly and the surface layer can be recycled before the artificial turf is constructed. In order to ensure the quality of the turf and cost-effectiveness, the above four factors should be mainly considered. In addition to these four main factors, there are other factors such as the treatment of the base layer, the choice of adhesives and so on. In short, in actual engineering construction, various factors should be fully integrated with the economic investment of the investor, the characteristics of the actual use of the lawn and other factors, relying on scientific theories and technologies, to achieve the most economical, applicable and effective principles.Return to Sohu to see more
