Laboratory under artificial grass growth state

1 in the laboratory tests, samples less in width (23 ± 2) ° C test temperature, place 3h tested. Field test the ambient temperature shall be subject to the outside temperature, the grass surface is not available 0 as the drops of water.
Two permanently attached to the soles barbell on the back of the shoe, artificial grass as close as possible on the sole part of the place around a nylon belt, nylon belt at the other end of the table mounted a rally, and then in the horizontal direction parallel to the ground slow, steady pulling tension table, record the start slip sneakers minimum force.
3 in three places in the field test in four directions, each direction measured perpendicular to the previous one; every where the average is taken in four directions where the friction coefficient of the friction coefficient of the stadium three the average; friction coefficient difference of the maximum take three.
Annex D (normative) wire grass n | Flexible Test 1].
1 Scope This method can be used in experiments or field Che dust test wire grass n | elasticity.
Two principle a metal foot model weighed repeatedly falls on the specimen, and then check the extent of the damage the sample, and whether permanent deformation.
Test conditions 3 laboratory temperature (23 2) ° C, less rare specimen temperature for 3h in the test tested take two implicit length of at least 125, width of at least 125 samples for testing.
4 Test Equipment
1 Repeat the weight from the sample from the upper (40 5) in height falls under the action of gravity, a frequency of (402) times / in;
2 - a (5 0.1) Kg of weight;
13 - a collision surface is formed by two gold * Li rods, each about 50 to 60, a thickness of at least 10, the hit | 0.1 from the edge of the leg 1, two metal rods to keep parallel to and a distance (38 2) hidden;
4 a sample carrier plate, perpendicular to the direction of the edge rod hook rlf move back and forth in the (402) within a distance (750 20) / in length movement.
5 Test Procedure
The specimen is clamped in the power punch rli device, note that the test material is not bent. Start machine (2000020) times pick attack. After a (30 l) in the recovery period after check whether there is any deformation of the specimen Yao.
6 Test Results
Note any significant deformation, distortion, especially to see that there are cracks or damage Merger.

synthetic turf greening the urban environment plays a crucial role

synthetic turf greening the urban environment plays a crucial role

In this colorful world Bingfen of time, always missed the green embellishment, whether it is a big city or a small park, and if less greenery dotted will be overshadowed by a lot of people in addition to outside in some trees, but also plant some synthetic turf in the city to create a green environment, so it is synthetic turf regardless of people's lives or in greening the urban environment plays a crucial role.

Plants are part of life, and other plants, plants and animals that exist between the close and important links. Sometimes, we have no choice, only undermine these relationships, we should be cautious, however, to fully understand how we are in time and space have long-term consequences. But herbicide market is booming, is widely used to kill large-scale production plant chemicals, herbicides industry is flourishing Suddenly, they certainly are not unique to the cautious attitude.

We never thought, destroying landscapes many great events. To give an example here that sage district in the west, ranch saint destructive large-scale projects. If from a historical perspective, the significance of the landscape, to understand a business, it should be like this. Because natural scenery here is to create a view of the many interactive and dynamic power of images. It is like an open book before us, we can understand why the Earth is so, why do we want to maintain its integrity. Now, however, open book, there is no one to read. Millions of years ago, this growth is the land of saints and highland plateaus in the west slopes of the low zone, is a huge Rocky Mountains elevation of the land. This is a very harsh climate during the long winter, when the snow from the mountains and plains are covered with thick snow, because of lack of rain in the summer, hot and dry, a huge threat to the soil, dry wind blows away leaves and stems in the water.

As a landscape evolution, in the highlands of plant colonization wind up the need for a long trial and error process. Plants and a plant growth have failed. The last category has the survival of both plant growth and development all the necessary functions. Sage, very short, is a shrub that grows in the hills and plains, it can be small gray leaves retain moisture and resist drafts. This is not accidental, but the long-term result of natural selection.

To say that in China that the artificial grass market is quite broad

artificial grass is enabled in European countries, and their artificial grass material properties in general than China, China's introduction of artificial turf with less than 10 years, with this artificial grass fibers constantly updated and manufacturing machinery constant change , the development of China's artificial grass or quickly.

Before 1997, China's artificial grass fibers are all imported from abroad, to comply with the foreign industry testing standards. At that time our country was affected by foreign artificial grass fibers exclusion, therefore, from around 2001, China began using imported raw materials, finished products assembled in the country, while the domestic industry has no uniform testing standards. Shanghai is currently only developed on the special monitoring of outdoor sports venues normative documents, in fact, the quality of artificial turf on the market is uneven, the school in the introduction, there may ignore this. To say that in China that the artificial grass market is quite broad, it can invest a good project.

Many manufacturers of artificial grass instead of relying on innovation to improve product quality, but trying to fraud posing as "imported grass", this distortion of the "development" as soon as possible if you can not stop, will inevitably lead to the artificial turf industry into trouble. Artificial grass is a kind of plastic, chemical material production tantamount grass products, mainly for the construction of sports venues green lawns. But because of the plastic chemical technology is relatively backward, and sports facilities construction units in order to ensure quality, most require the use of imported artificial grass.

High-end domestic market is mainly imported turf artificial turf; the high-end market is mainly based on "raw materials import and domestic production," the main; lawn market is based on the low-end domestic raw materials mainly. From the current situation of China's economic development, due to high prices of imported turf, the market's capacity is limited, therefore, these products will become increasingly smaller customer base. For the low-end market lawn, since the market increasingly demanding high quality products, its quality can not meet the demand gradually.

Artificial grass and now have 40 years of history, it is the beginning originated in the United States, it was not in the ceiling of the natural grass can not grow underneath, in order to solve this problem, the use of artificial grass. Since then artificial grass from the U.S. to the worldwide popularity, the formation of grass Americas, Europe, grass, Australia, and Asia Grass Grass split the market situation and the Americas because of a long history of grass, materials and advanced technology have a stronger market competition force. Artificial turf pitch has a very big advantage, and no doubt will be more and more widespread use.
