Four matters should be noted before construction of Sports Artificial Grass. Sports Artificial Grass is a non-life of plastic chemical fiber products as raw materials, the use of artificial methods to produce simulated lawn. It is to solve the use of high intensity, extreme conditions of growth and other natural lawn is not easy to grow and should not be an important way to build lawn. Compared with the natural lawn, Sports Artificial Grass has a very obvious advantages and disadvantages. Such as the use of all weather, rain, snow weather is small; maintenance is simple, low maintenance costs; material environmental protection, the surface layer can be recycled, etc., is a natural lawn irreplaceable, therefore, Sports Artificial Grass is very suitable for use frequency High primary and secondary sports ground or various training grounds. However, because the Sports Artificial Grass is made of chemical fiber material, and asphalt or concrete as the base layer, so its surface hardness, poor cushioning performance, easily lead to athlete ankle and knee injury; the same time the surface temperature changes, especially Is in the summer, the maximum temperature of up to 52 ℃, such a high temperature on the athletes of the competitive state and the environment will have a great impact.

In recent years, with the Sports Artificial Grass construction technology constantly updated and the development of fiber materials and filling materials, making the Sports Artificial Grass many shortcomings, such as surface hardness, poor cushioning performance is gradually improved, of course, these are the right choice of lawn materials and To ensure scientific and rational construction of technology and quality under the premise can be achieved. Before the construction of Sports Artificial Grass, should be mainly considered the following factors: Sports Artificial Grass type, Sports Artificial Grass used fiber material (PP or PE); filling material type (silica sand, rubber particles or a mixture of both) and filling depth; Design and so on.

(A) the choice of Sports Artificial Grass type
Sports Artificial Grass lawn can be divided into two types: mosaic and weaving. Knitted lawn with nylon weaving, finished into a blanket. Compared with the mosaic tufted lawn, weaving Sports Artificial Grass production process is complex, the price is relatively expensive, the lawn surface hardness, cushioning performance is not good, but the lawn is uniform, strong and durable, very suitable for tennis, hockey, grass bowling movement. Compared with weaving lawns, mosaic lawns have longer lengths and larger variations, ranging from 12mm to 55mm, and can be adjusted according to special needs. Mixed with quartz sand, rubber particles or a mixture of the two, the appearance and performance of the natural lawn is also closer to the indoor and outdoor can be installed for soccer, football, baseball and so on.
(B) the production of artificial lawn materials and choice
Sports Artificial Grass production materials are generally two: polypropylene (Polypropylene, PP) and polyethylene (Polyethylene, PE). PP material of Sports Artificial Grass solid, small buffer force, generally applicable to less impact of sports such as tennis and so on. The PE material of the Sports Artificial Grass soft texture, good buffer performance, the role of athletes damage, for the impact of larger sports such as football, football and so on. You can also mix two kinds of materials to make Sports Artificial Grass, so you can combine the advantages of both to meet the needs of special games. For some high-intensity sports competitions, in order to improve the quality of the game and minimize the damage of athletes, in the choice of Sports Artificial Grass, the general choice of a relatively high height of the fiber material, usually 25 ~ 50mm, and to choose PE Sports Artificial Grass or PE / PP blend of Sports Artificial Grass. In the construction of Sports Artificial Grass sports ground, in the choice of Sports Artificial Grass height, the general consideration of the overall budget of the stadium, a relatively high height of the Sports Artificial Grass, the construction and maintenance costs are relatively higher in many schools in Europe often choose a height of 19mm Lawn, 25 ~ 32mm height of the Sports Artificial Grass can provide a high quality sports field, and some professional sports ground Sports Artificial Grass height is usually selected in the 50 ~ 55mm, this height is usually considered the ideal Sports Artificial Grass ceiling. Some of the rugby stadiums in the United States, the tallest lawn of Sports Artificial Grass, about 70mm, but in general, such a high Sports Artificial Grass stadium is rare.
(C) the filling of Sports Artificial Grass, filling material selection
1. The artificial lawn filling material is usually sand or rubber particles, and sometimes the two mixed use, in the mixed use, the proportion of the two according to the specific circumstances, the usual mixing ratio of 70% rubber particles + 30% sand The In the past, 100% of the sand was often used as a filler, in order to increase the stability of the lawn base, but with the Sports Artificial Grass manufacturing process matures, its basic manufacturing is relatively perfect, so in the past to fill the sand to stabilize the practice of the lawn Has been gradually eliminated, and now use more filling method for 100% rubber particles. Fill the sand or rubber particles are mostly medium size, and must be washed before filling it. For some of the impact of the larger sports such as football, football, etc., should be appropriate to increase the proportion of rubber particles, to minimize the damage of athletes. For the impact of small or almost no impact on the role of sports venues such as tennis courts, as long as the site hardness can be uniform, the buffer is not demanding, so the choice of filler material in the larger room. 2. Fill depth The depth of filling of quartz sand or rubber particles in Sports Artificial Grass can be determined depending on the purpose of use and the height of the selected lawn beam. For the impact of the larger intensity of the movement, you can choose a longer beam of artificial lawn and fill the deep filler, the general artificial football field lawn suitable filling depth of 5mm from the tip; and for the requirements of high flatness, good uniformity Such as hockey, the beam can be properly reduced, the filling depth can be increased, even with the lawn surface flat. The Pennsylvania State University study shows that the ruggedness of the soccer field and the surface hardness of the stadium can be controlled to a certain extent by the type of filler and the depth of filling.
(4) Sports Artificial Grass drainage design
Some Sports Artificial Grass design with drainage system, lawn cushion with permeability, the base layer in the design of a drainage pipe, the construction of such lawn structure is more complex, higher cost. But some systems do not design the drainage system, it is necessary to rely on the surface of natural slope drainage, so the surface construction requirements are higher. Before the construction of Sports Artificial Grass, in order to ensure the quality of lawn and cost-effective, the above four factors should be the main consideration. In addition to these four main factors, there are other factors such as grass-roots processing, bonding with the choice of glue. In short, in the actual construction, should be the factors and the investor's economic investment, the practical use of lawn and other factors fully integrated with scientific theory and technology as the basis, the greatest degree of economic, applicable and effective principles.
