The Natural Turf Of Artificial Turf Has Its Own Advantages And Disadvantages
- Jan 31, 2018 -

Artificial turf was born in the 60 's in the United States, it is the life of plastic chemical fiber products as raw materials used artificial method of the lawn. It is not like a natural lawn needs to consume the necessary fertilizer, water and other resources, to meet the 24-hour high intensity of the movement needs, and maintenance of simple, rapid drainage, excellent site flatness. Artificial turf is widely used in hockey, baseball, rugby special venues, football, tennis, golf and other sports of the public driving range or as a ground to beautify the indoor environment.

Comparison of natural and artificial grasses in nature

In the late 80, the introduction of artificial turf, until the middle of 90 to get a large area of the promotion. Together with the plastic runway, it became the standard Model for school sports venues, replacing a large number of sports venues originally planted with natural lawns. Although due to sports safety, site characteristics and public awareness, the application of artificial turf has been limited to a certain extent, but with the development of science and technology, artificial turf production technology has been continuously innovated and improved. Nowadays, the sixth generation artificial lawn made of open net single filament filament is more close to the natural lawn in the area of shock absorption ratio, ball rebound rolling and steering value, and even has more advantages in some characteristics. In the exercise safety, the new generation of artificial grass fiber on the surface coating, polymerization of raw materials improved can effectively reduce skin scratches and foot sprain and other sports injuries. The advantages of artificial turf and natural turf are relatively prominent, the shortcomings and shortcomings are also objective existence, the choice of use must be based on the actual situation to consider comprehensively.


Sports performance compared with natural turf, artificial turf is usually built on a much larger site, the friction coefficient of chemical fiber is often smaller than lawn grass blades, in football, the performance of the ball speed too fast, rebound rate is too high, thus increasing the control of the ball athletes difficult.


The advantage of the artificial turf relative to the natural turf is that the uniformity of the site is excellent, the smoothness is much better, and the condition of the site due to climate, conservation and other factors can be avoided, which will affect the competition.

The fine contrast between the true and false lawn


Impact of the environment on the air condition The natural lawn is composed of green plants, can absorb carbon dioxide through the physiological metabolic process of photosynthesis, release oxygen, and can absorb sulfur dioxide, hydrogen fluoride, ammonia, chlorine and other poisonous gases, play the role of purifying the air. The natural lawn has obvious blocking effect on dust, and the measured data shows that the dust concentration in the bare ground is 13 times times higher than that of the lawn in the three or four-level wind. Research shows that 25 square meters of lawn can be a person's exhaled carbon dioxide absorption, into oxygen, to meet the human respiratory process required oxygen. Artificial turf is made of polyethylene, polypropylene, such as non-life materials, can not carry out the metabolic activities of green plants, there is no regulation of atmospheric carbon and oxygen balance role. Although artificial turf can block dust to some extent, it does not have the function of absorbing poisonous gas to purify the atmosphere. In addition, the low process level of artificial turf fiber often contains chlorine impurities, in high temperature, strong sunshine conditions will decompose and release chlorine, damage air quality.


Effects on climate the flat bed of the natural lawn is a silt mixture, and the structure has sufficient pores to accumulate water in the process of irrigation and precipitation, which plays a role in water conservation. When the climate is hot, the lawn grass uses the root to absorb the deep water, through the transpiration effect takes away the massive heat of the surroundings, effectively reduces the ground temperature, adjusts the certain range the microclimate. The lawn bed structure of artificial turf is composed of rubber, concrete or asphalt, which can not play the role of water conservation, so it can not reduce the surface temperature, and its heat capacity is small, which causes the surface temperature to be much higher than the air temperature, especially in the enclosed stadium. At noon in the summer, the artificial turf can be observed in the ground near the surface of the air has a noticeable distortion of the phenomenon of heat. The experimental data show that the average surface temperature of the natural lawn is lower than the temperature 2 ℃ to 3 ℃ at high temperature above 30 ℃, while the surface temperature of artificial turf is higher than the temperature 6 ℃ to 11 ℃, and the surface temperature of artificial turf increases obviously higher than that of natural lawn. In the summer, the artificial lawn surface temperature is very high, if at this time the user with more intense friction, the contact area of skin will be seriously injured.


The residues of the natural turf produced by the final product are decomposed into organic matter and returned to the soil under the decomposition of microorganisms in the sediment of the ping bed. Finally, the residual non-toxic, harmless silt mixture can be added to the organic matter and then used for another.

Environmental


The main components of artificial turf are non biodegradable materials, after 8-10 years of aging eliminated, the formation of tons of high polymer waste. Abroad are generally from the professional company to recover the degradation, and then realize the renewable use of resources, the domestic can be used as the foundation of road engineering filler. It is also necessary to remove the base layer constructed from asphalt or concrete if the site is converted to other uses.
