Artificial grass has the following characteristics: it can meet the needs of 24 hours, all-weather, high-intensity sports, simple maintenance; anti-corrosion, sun protection, environmental protection, no harm to the human body; dense and secretive water infiltration hole, so that the water after the rain and its degree is much smaller than that of the natural lawn; leveling and no bump gives the athletes a fair and equal technical space and safety guarantee. Each artificial grass fiber has been subjected to tensile treatment and has high strength and toughness. The unique colored grass belt changed the traditional spraying method to integrate various functional lines in the sports ground without fading; the water resources used for sprinkler irrigation were saved.
Although the construction cost of artificial grass varies, and the construction method varies from place to place, the overall structure can be divided into three parts: the basement is a basement, the middle is a buffer layer, and the top is a lawn. floor. The base layer is the bottom layer of the artificial turf structure. It is usually composed of a dense soil layer, a pebble layer and a concrete layer or an asphalt concrete layer. The buffer layer is designed to cushion shock and impact. It is usually closed by a polyvinyl compound. Porous foam and cushioning layers vary widely in the thickness and composition of various types of artificial turf. Artificial lawns can be divided into inlaid and woven two production methods, woven lawn woven from nylon. Carpets, mosaic lawns are longer, and fiber lengths are different.
Artificial grass consists of grass seedlings, woven grass bottoms and primers. Most domestic grass seedlings are polypropylene, commonly known as PP. It has poor UV resistance and contains a large amount of heavy metals, such as cadmium and nickel, which cause serious damage to human health. Grass seedlings have poor temperature adaptability, especially at low temperatures outside the winter, and tend to harden and fracture. Most of the foreign product materials are made of polyethylene polymers, often abbreviated as (PE), and are currently used in international competitions and European top clubs. PE excels in resistance to ultraviolet light, mechanical abrasion and temperature differences. Artificial turf does not require a high level of foundation ground. Whether it is cement concrete, asphalt concrete foundation, hard sand or cement stabilization, artificial turf can be laid. The most stressful is that the maintenance of artificial grass is very simple and durable.
In the 1970s, artificial grass was born in Europe. It can be used for football, basketball and sports because it can meet all-weather within 24 hours, high-intensity sports needs, simple maintenance, antiseptic, sun protection, environmental protection, quick drainage, and very good – grounded. Tennis, hockey, football, golf and other sports and leisure venues. However, due to some safety and sports numerical reasons, it has not been widely used in professional sports venues. With the development of science and technology, the ratio of shock absorption, rolling ball and turning value of natural turf is basically the same. This year, UEFA decided that starting next season, the European Club and the national team will be allowed to hold events on the artificial turf, which means that the artificial turf will enter a completely new field.
