Clearly artificial turf and natural grass edge difference

Engage in green for decoration, the choice of what kind of lawn good? artificial turf which brand is good? Artificial turf, multi-purpose sports stadium and kindergartens in places. Compared to artificial turf, natural grass, artificial grass upfront investment than investment and large, which it needs from the Song Shi, transplant sod, fertilization, water, conservation, etc. a lot of manpower, material resources, and artificial grass will not have to consider these issues, only pave the venue, there is a fixed drains, on the line; small investment for a one-time, required less manpower and resources.

TurfSoccer artificial turf, as natural as TurfSoccer closer to natural grass. TurfSoccer baby home turf is the people, the kids playground paradise, it is garden construction, home decoration among a beautiful landscape.

artificial grass market prospects are widely good

artificial grass originated in the United States in 1968, the invention of a military project, because of its special wear-resistant, can be frequently used, are widely used in football, baseball, soccer and other sports venues. It is estimated that the world's use of artificial grass has reached more than 200 million square meters, and the most widely used is the stadium.

In recent years, with the artificial grass in the manufacture of materials, weaving, and other aspects of the filler material and improve them with the difference between natural turf shrinking. In the 21st century, artificial grass used to rationalize its use in international competition has gradually been recognized. As FIFA President has decided, in 2010 FIFA World Cup South Africa on allowing the use of third-generation artificial grass.

With sports and popular recreational sports in our country flourish, artificial turf stadium has become a symbol of modern sports facilities. In recent years, the National Stadium from school, kindergarten through community leisure venues have formed an increasingly strong trend.

Artificial grass products have been mostly used PU Backing materials and technologies that replace the ordinary bottom back, because high technical threshold, currently in the country only a few manufacturers can produce. MIE series of artificial grass is based on modern sports venues comfort requirements for design and manufacturing, he fully mimic natural grass, highlighting UV resistance, abrasion resistance and stiffness effects, the maximum range for a variety of sports venues. From professional venues, training venues to the public as well as medium and large institutions stadium, sports venues around the world has its role to play.

Currently, artificial grass has been well received by the school, organizational units, stadiums and other public places of all ages. Also, because the artificial grass carpet not only non-slip, dust, easy to clean, and the shape of real grass, a green feeling, now become a common upholstery, and get ordinary people's favorite, therefore, artificial grass market prospects are widely good, which is the domestic artificial grass manufacturers are constantly emerging, the reason for the rapid development of the industry.

Now the international community, such as Ajax, Real Madrid, AC Milan and other famous football clubs have artificial grass stadium. Development of artificial grass late start, mid-1990s, China began from abroad for the laying of artificial grass sports fields, some domestic enterprises have begun to develop production of artificial grass, artificial grass has now been widely recognized by everyone, Beijing Guoan, Shanghai Shenhua, Shandong Luneng Football Club has its own artificial grass stadium.

Analysis of synthetic grass on health hazards do?

Analysis of synthetic grass on health hazards do?

Before everywhere green lawn, a lot of parents do not worry kids to play at that level, worried about the bacteria on the grass too much contact with the child gets sick, which led to the child lost a lot of outdoor playful, all these years, those green lawn was gone, replaced by a synthetic grass, but it does not eliminate the appearance of the parents' concerns, but they are more worried about the artificial grass will be even greater harm to the child, and that the fact whether, as we had feared it ? Today we are Beijing synthetic grass Xiaobian just as we explain.

Before we worry about real grass will hurt the grass because those children are in contact with soil is very easy to breed bacteria, a child's immune system is low, easy to be infected sick, so do not worry. But the artificial grass is not the same, this production of materials from talking about it, we all know that synthetic grass is made ​​with a chemical substance, which is the parents' fear of harm to the child's reason, but in fact the regular synthetic grass the use of chemical substances are harmless, not only that, these substances can effectively prevent the growth of bacteria, thus the composition of this grass lawn relatively fewer bacteria, and because such a lawn into one of You can prevent people from direct contact with the ground, thereby isolating the soil on the human body injury. And professionals also said now that the production of substances like very much, many aspects of life have applied to, so we do not have to worry.

However, although it will not hurt the body, but for security reasons, TurfSoccer suggest that you still have to pay attention to some, for example, to regularly clean up the lawn, the lawn to prevent problems as time goes by, and secondly to often to check the body, in fact, both whether they have used the lawn, this is supposed to do, just in case anyway you can, find a peace of mind thing!

Six-generation synthetic turf compared the development process

Six-generation synthetic turf compared the development process

synthetic turf is currently the most widely used in sports venues and a natural grass is very similar to the synthetic turf, this synthetic turf after years of development has now developed to the sixth generation, during which the people through continuous efforts, each generation of synthetic turf more than the previous generation has many advantages, but also the development of this synthetic turf and makes extensive use of sport in our country even faster pace of development, a lot of professional sports is also used in this material.

the development of synthetic turf can be divided into six generations, starting with the first generation of synthetic turf, turf for this person has a relatively large damage, burns on the skin, but also in the maintenance takes a lot of water, and its cost is also a lot of people can not accept. The second generation of synthetic turf; this material is mainly pp fiber grass, the second generation of synthetic turf and the first generation is basically the same, but the length of the grass is about 25mm. Third generation synthetic turf needs to be filled sand, relatively hard texture, the skin is a relatively large damage.

The fourth generation of the synthetic turf, the material and the third is very similar, but with a layer of an elastic layer has a certain elasticity, the height of about 60. Fifth generation; synthetic turf yarn every blade of grass is an independent body, you need to fill sand or rubber granules, texture is soft, the athlete's injury is relatively small. Sixth generation; every blade of grass is an independent body, soft on human damage is very small, with good elastic layer can improve the athlete in motion the level of play, increase the movement of the buffer, and is very similar to natural grass.

artificial turf is to determine the quality of several major issues

It is understood that the shoes and turf interaction interface is appropriate and reliable site surface grip, ball rebound after touching the turf, annual consumption, as well as the maintenance of turf, artificial turf is to determine the quality of several major issues. In TurfSoccer's Professional Soccer & Football Grass S50435 products, for example, according to its turf unique filling system and shoes grip extent, controlled formation of extrusion, and generates secure grip force and soles fit, while its "spatial memory" Performance it is able to help the turf quickly reinstate the system, gives the best stretch of turf while maintaining consistent appearance. It is worth mentioning that, in abandoned tire rubber and other inferior filler flooded low-end artificial turf today, TurfSoccer but to devote themselves to come up with a five-year period ECOFILL ecological characteristics of this crystal, all-natural materials ECOFILL and grains normal size, and its force after spatial memory function and a unique shape and foam technology, forming a natural soil with very similar characteristics, there are not as natural soil compaction due to the effects of weather, wet, water, uneven. TurfSoccer will complete a course in the use of natural features and filled with all the defects of the artificial turf system, which is an integrated and systematic innovation!
   
Data show that, TurfSoccer artificial turf for its low consumption ensures longer life of the use of higher frequency, even after years have also guarantees 100% recycled and TurfSoccer artificial turf never appear as a single product, but in the the laying of the first to seek harmony with the environment, durable a systems engineering. No wonder that a similar high quality artificial turf products will become more and more the choice of the new football field, and in the Blatter seems "artificial turf instead of natural grass, football is a part of normal development and change."
