Artificial grass yarn (SyntheticLawnThread), is the main material of manufacturing artificial grass, it provides the best environment for athletes, improve the security of the airport, use our wide. Artificial grass uses the principle of bionics, campaign activity, foot, bounce of the ball speed and natural grass is similar, and have good water, 20 minutes drain clean after heavy rain. Artificial lawn in addition to a variety of excellent performance of natural lawn, also special wear-resistant. Artificial turf runway 5mm the following can be used in track and field spikes. Artificial grass Cove fade, convenient maintenance, Foundation requirements are not high, asphalt, cement and construction of hard sand and short. It is especially suitable for long training time, using a high density of primary and secondary sites. Cost performance and there is a clear advantage, comparing, wear resistance, daily workers maintenance, repairs, water consumption and other factors, is artificial turf the decade more than 5 times less than that of natural grass. [1] material of the artificial grass: artificial turf material liquid colored nylon fiber, or PVC, polypropylene melt spinning method, such as a flat wire, typically will add the amount of UV absorbers (anti-aging barrier layer), the line density of 165-1100dtex. [2] of artificial grass weaving: manufactured by a similar method of aubusson rugs production, organic method of weaving, tufting, knit Terry law constitute an imitation grass fiber, in order to make Terry cloth very well fixing at the end, artificial turf should be on the back of the fabric-coated synthetic LaTeX. [3] the structure of the artificial grass: artificial grass is connected by pavement and grass fibers constitute a—[surface]. Evenly spaced woven hole on the surface, grass fibers staggered woven by weaving hole on the surface, then fixing glue, brushing the surface of the back, fixed grass fiber, constitute a whole lawn. Artificial turf can be laid directly on the surface of concrete or hard sand, simple construction, repair and maintenance easier, especially suitable for the use of frequent training ground, such as football, tennis, track and field and other various sports venues; the lawn permeable material permeability, not bonded to the underlying. [4] development of the artificial turf of: movement is the artificial grass in the early 1970 of the 20th century were first to Europe, America and other countries in the region began to produce developed, as football, tennis, golf and other sports professionalization, industrialization and commercialization development of sports industry development of the artificial grass made some progress in recent years. Foreign artificial grass development process: since the United States in 1964 built since the first artificial turf Stadium, after more than 30 years of development. First generation: (1975-1977) nylon fiber products, the sand, no elastic layer, burns to the skin, the conservation of large water. Second generation (1977-present) nylon fiber products, the sand, elastic, skin burns, conservation of water consumption. Third generation: (1982-1985) PP fiber with fiber grass, sand-filled, non-elastic layer, the quality is hard, burns to the skin. Fourth generation: (1985-present) PP fiber with fiber grass, sand-filled, flexible, quality is hard, burns to the skin. Fifth generation: each stem as separate single filament, fill sand/rubber capsules, soft, not open fork, no burns on the skin, anti-UV properties of grass fiber better. Sixth generation: using environmental material-the-the polyethylene as raw materials (easy to recovery, and stacked and incineration), each root grass stem for open network single fiber long silk, mass soft, no skin burns, grass fiber anti-UV performance better, entire system of elastic pad layer + dense of fill property, increased on movement of buffer, does not distributed smell, does not on human produced effect, resembles natural grass. In 2004, MIE companies developed together with BONAR companies netted with low friction of single fiber artificial grass products, representing the highest level of artificial grass. After the 2006 World Cup, attention the artificial grass. 2010 South Africa World Cup will attempt to use the latest generation of artificial turf. Artificial turf development process in China: domestic introduced from 1999 imported materials to create the first artificial turf sports ground, started a campaign promoting the use of artificial turf in China history. As the movement of artificial turf in the country rapidly promoting the use of a large number of foreign brand of artificial grass hold Fun entering the Chinese market, where also gradually bred a number of national movement under synthetic turf production enterprises. As the sport and the mass development of leisure sports in China, artificial turf Stadium has become a symbol of modernization of China’s sports facilities. In recent years, national stadiums, kindergartens from school to community leisure venues has developed a growing share of the new trend. [5] what is the best artificial turf: artificial turf and the quality of life depends mainly on the quality of grass fiber. Poor quality of grass fiber UV irradiation, temperature change, such as acid rain environment easy to embrittlement, weathered (the industry called “fibrosis”), after Stampede into powder, after they have been exercising inhaled, will seriously affect health. High quality artificial turf was not simple in structure, different from traditional monofilament mesh of grass fiber or slices, but functions such as anti-aging, anti-ultraviolet and so on, subject to GB/T20394-2006 of the national standard of the artificial turf for sports and Germany DIN standard, by 6,000 hours light and ageing resistance test are to be the best artificial turf. Not long ago, Sweden scientists after a long period of research and testing, prove that the use of artificial grass, compared with the use of natural turf and will not increase chances of athletes were injured. New generation grass property is very close to natural grass, with good moisture retention, sand-fixing characteristics, improving the stability of the entire site, so you can reduce the athletes in sports skin abrasions resulting from ground in the process, at the same time can provide maximum protection to the player’s ankle. [6] artificial grass features and advantages: 1, artificial lawn in addition to a natural grass various excellent performance, but also special wear-resistant, colorful, around once and environment and building supporting more display its overall modern color. 2, artificial grass Cove faded, convenient maintenance, Foundation requirements low, short construction period, the construction on the surrounding environment pollution, life of 5-8 years of normal use, caress for the majority of users the new high-tech sport of building materials. 3, also has an excellent physical and chemical properties of the artificial grass, artificial turf after severalAfter wearing test of 100,000, its fiber weight loss only 2% per cent. In addition, the tension, in water, the flexibility is very high, about 20 minutes after the heavy rain can clean drainage. At the same time, it can be prepared according to the different areas of climate characteristics of raw materials, so sod adaptable, can use in climate such as Alpine, high temperature and high altitude areas. [7] comparison of artificial turf and natural grass: the use of frequency: high clock frequencies using the artificial grass. Natural lawn needs regular maintenance, using low frequency. Adaptability of weather: rain does not affect using the artificial grass, 20 minutes after the rain stopped. Natural lawn 3-5 hours after the rain stopped. Durability: artificial turf without any effect. Natural lawn durability is very low, maintenance could not keep up with easy sky of loess. Usage: artificial grass is no special requirement. Natural lawn tips, high heels, hook-shaped spikes, sharp objects such as bicycles and motor vehicles not in use. Durable life: artificial turf over 5 years. As the degree of maintenance may be natural turf. Human damage and repair after treatment: artificial turf maintenance process simple, and use their own maintenance, patch color difference and sign maintenance fast and inexpensive. Shall promptly natural lawn planting and pest and disease prevention by professional staff, high cost of maintenance and growth of a longer time. Environmental factors: artificial turf on the environment and no poisonous air, recycling of waste can be. Use large quantities of water resources and natural lawn spraying pesticides can cause water pollution, at the same time the breeding of insects and bacteria. Cost: artificial grass (for reference only) $ 80-150/m2. Natural lawn (for reference only) $ 20-30/m2. Maintenance cost: artificial grass within 3 years without maintenance, approximately $ 1.5/m2 after 3 years (for reference only). Natural lawn 10-15/m2 (for reference only). [8] characteristics of the artificial grass: 1, with better flexibility and adequate buffer force. 2, air permeable. 3, significantly reducing maintenance costs, in particular in line with urban water conservation requirements. 4, in line with environmental requirements, layers can recycle the lawn. 5, increase campaign coverage, reduce noise on the playground, and have the effect of shock absorption, decompression, meet the requirements of open teaching. 6, using silver quartz sand or sand fill, not dirty clothes during the student movement and the environment, and direct all the marking of weaving in the playground no longer frequent marking distressed. 7, economical and practical, investment guarantees that the life expectancy of more than seven years at a time, almost no follow-up maintenance costs. 8. construction and installation phase short and quick. [9] on the new generation of artificial grass is used for airport: in the United States a study on airport staff survey shows that use artificial turf systems can in large part on improving airport security. 1 artificial turf surface will not provide wildlife needed water, food or shelter, thus reducing the influence of wild flora and fauna on the airport, eliminate wildlife damage to the aircraft. 2 the runway shoulder more robust to ensure aircraft safety, elimination of vehicles sliding off the runway into the soft natural lawn of potential risks and resulting costs. 3 reduce soil erosion. 4 reduce gas shock wave on soil erosion. 5 improving the drainage capacity. 6 enhanced vision, ensuring that pilots can clearly distinguish the runway and grass. 7 simplified turf management no longer sent to the airport operations area lawn maintenance, on the whole, improve airport security, and reduce environmental pollution brought by the use of herbicides and pesticides and lawn maintenance costs. 8 reduce FOD (ForeignObjectDebris) damage to the aircraft, fundamentally eliminating FOD threats to flight safety.
