How to choose artificial lawn?

1. Observe the shape of the grass:

There are many types of grass, U -shaped, m -shaped, diamonds, stems, no stems, and so on. The larger the width of the grass, the more materials are. If the grass is added to the stem, it means that the upright type and the return elasticity is better. Of course, the higher the cost. The price of such lawns is usually more expensive. The turf is consistent, smooth, and no messy silk, indicating that the grass is elastic and the toughness is good.

2. Observe the background back:

If the back of the lawn is black and it looks a bit like a custard, it is general -purpose buttobene gel; if it is green, it looks like a leather, that is, a higher -grade SPU gel. If the bottom cloth and glue look thick, generally indicate that there are many materials, the quality is relatively good, it looks thin, and the quality is relatively poor. If the back of the back is thin and uniform, the color is consistent, and there is no primary color of the grass, indicating that the quality is better; thin and uneven, colored, leakage of the original color of the grass, indicating that the quality is relatively poor.

3. Touch the filament feel:

Most people have to look at the grasshills when they touch the grass, and they are not comfortable with their feelings. But in fact, the soft and comfortable lawn is the poor lawn. You know, the lawn is used in the daily use of the lawn, and it rarely uses the skin to contact directly. The hard grass is just powerful, with greater reflection of elasticity and toughness. Broken. It is very easy to make grasshills. It is very difficult to make a straight and high bomb. It really needs high -tech and cost.

4. See the anti -pull rate of the grass:

The law of the lawn is one of the main technical indicators of the lawn, which can be measured by the method of pupae. Cut a cluster of straw silk with your fingers, pull out hard, and cannot be pulled out at all, generally the best; sporadic unplugs, and the quality is okay; if you are not strong, you can pull out more ones. Grass silk, basically poor quality. SPU -back gum lawn adults should not be completely unplugged with 80 % of the power. Generally, but buty p -benzene can generally fall off a little bit. These are the most visible quality differences in two kinds of gums.

5. Pressing the shredded elasticity:

Put the lawn on the table and press it with the palm of the hand. After loosening the palm of the hand, if the silk can be obviously rebounded and restored to the original, it means that the grasshopper elasticity and toughness are good. For a few days or longer, then dry in the sun for two days to observe the capability of the lawn to restore the original.

6. Tear back:

Grab the lawn with both hands, tear the back of the bottom like tearing paper, it cannot be torn at all, it must be the best; it is difficult to tear and better; it is definitely not good. Generally, SPU gels can almost tear at eight percent of adults; how much cannibene -butd phenylphenylene gel can be torn, which is also a difference between the two types of gels that can be seen obviously.

Pay attention to the purchase of artificial lawn to buy?

First, raw materials

The raw materials of artificial lawn are polyethylene (PE), polypropylene (PP), and nylon (PA).

1. Polyethylene (PE): The cost is relatively high, the feel is softer, the appearance and sports performance are closer to natural grass. It is widely accepted by users. It is currently the most widely used artificial grass fiber raw material on the market.

2. Polypropylene (PP): Grass fibers are harder. Simple fibrosis is generally suitable for tennis courts, playgrounds, runways or decorations. The wear resistance is slightly worse than polyethylene.

3. Nylon: It is the earliest artificial grass fiber raw material and the best artificial lawn raw material. It belongs to the first generation of artificial grass fiber. Developed countries such as the United States have selected nylon artificial lawns, but the quotation in my country is high, and most customers cannot accept it.

2. The bottom

1. The bottom of the wool PP weaving: durable, good anticorrosive performance, good adhesion and solidity for glue and grass lines, and the price is 3 times that of the PP woven department.

2. PP weaving bottom: The performance is average, and the bondage is weak. The bottom of the glass -dimensional dimension (at the bottom of the grid): Materials such as glass fiber are used to increase the strength of the bottom and the restraint of grass fiber.

3. The bottom of PU: The strong anti -aging performance, durable; strong adhesion to the grass line, and environmental protection without odor, but the cost is high, especially the imported PU glue is more expensive.

4. The bottom of the woven type: The bottom of the woven type does not use the bottom lining, and the glue is directly attached to the root of the fiber. This bottom can simplify the production process and save raw materials. : Label guns, but the bottom of the woven type has high requirements for equipment and technology, and this type of product has not yet appeared in China.

Third, glue

1. Buty phenyl lactal is the most common material in my country’s artificial lawn market. It has good functions, cheap costs, and well -integrated.

2. Polyette (PU) glue is a common material in the world. The strength and bundling force are more than several times of butyl -butyl, durable, beautiful, not corrosive, moldy and environmentally friendly, but the quotation is more expensive. In China’s market share in my country’s market share Low.

Fourth, product structure identification

1. Appearance. The color is bright and there is no obvious color difference; the grass seedlings are flat, the clusters are uniform, the overall is flat, the needle distance is uniform, and the consistency is good.

2. The length of the specifications. In principle, the football venue is better and better (outside the leisure venue). At present, the longest grass silk is 60mm. It is mainly used for professional football fields. The most common grass in the football field is about 30-50mm.

3. The density of the grass. Evaluate from two angles: First, look at the number of grass pins on the back of the lawn, the more the number of pins per meter, the better; second, look at the line distance from the back of the lawn, that is, the line of the row The better.

4. Grass fiber and fiber diameter of fibrous fibrous fiber. Common sports grass silk is 5700, 7600, 8800, and 10000, which means that the higher the fiber fiber fiber, the better the roots of each cluster, the more fine the grass silk roots, the better the quality. The diameter of the fiber is calculated with μm, generally between 50-150 μm. The larger the diameter of the fiber, the better the diameter, the big diameter is that the grass is thick, wear -resistant, and the small diameter of the fiber seems to be very thin plastic, which is not wear -resistant. The indicators of fibrus are generally difficult to measure, so FIFA generally uses fiber weight indicators.

5. Fiber quality. The greater the graphic wire with the same unit length, the better. The grass fiber pound weight is based on the fiber, and the mass defined by DTEX is defined as 1 gram per 10,000 meters fiber. It is called 1Dtex. The larger the grass fiber pounds, the thicker the turf is, the greater the weighing of the grass fiber fiber, the stronger the abrasion ability, and the greater the weighing of grass seedlings fiber, the longer the service life. However, the higher the cost of grass seedlings fiber pounds, the higher the cost, according to the age group of the athletes and the use frequency to choose the suitable grass seedlings, it is recommended to use a weighing lawn weighed more than 11000dtex.

6. Other aspects. The artificial lawn is used to use or to beautify the living environment. Therefore, the most important foot feeling and color quality are the first element of consideration. Whether the trajectory run above meets the requirements of the game.

Fifth, artificial lawn brand selection

Brand is an evaluation and cognition formed by users with strong product quality, good product image, perfect after -sales service, excellent corporate culture, etc. A trust between the establishment and the user. Therefore, when choosing an artificial lawn brand, you should first understand the history of the brand’s development. Whether it has stable product quality assurance, the testing and certification of authoritative institutions at home and abroad, and a complete and professional service system.

How to maintain artificial lawn?

1. Cooling

When the summer climate is cool, the surface temperature of the artificial lawn is relatively high. It does not absorb calories to reach the cooling effect like natural grass. After all, artificial lawn is PE polyethylene material. Thermal effect is very simple to play in such a high temperature environment. It is easy to have physical discomfort in the athletes and then reduce the quality and interest of the competition. Therefore, the surface temperature of the decline of artificial lawn is an important process of summer protection. Now it will generally decrease the temperature by watering the venue. This method is currently more useful. The professional league competition will be watered to the place before the premises to reduce the surface temperature. But the spray must be uniform and not too much, just spray the scene to moist.

2. Clean

Various wastes will inevitably occur in football venues. Whether it is artificial lawn or a place where natural lawns is needed, it needs to be cleaned. If it is simply floating and dust, natural rainwater can be cleaned. However, there are also many plastic waste, paper dandruff, peel and other waste demand for finishing and cleaning. Therefore, the protection operation of football places is necessary to include regular cleaning content.

Three, drainage

Summer is also a dry season. Generally, the dry season will be between April and October, especially in the dry season of the South China region, and there are many storms. Xiaoyu has no obvious impact on the artificial lawn place. When the artificial lawn has made a drainage system at the time of construction, and there is a small drainage hole on the back of the lawn. Generally, small and small rain will not affect the artificial lawn. The accumulation of water in the site. However, there are often heavy rainstorms in the summer, so that the rainfall of the large lawn is not so fast, so that the lawn will be swallowed by floods, rubber particles and quartz sand are washed away, causing severe damage to the lawn of the venue. Therefore, the summer artificial lawn protection drainage is essential.

Four, dehumidification

We all know that the air humidity in summer is relatively large, especially in the south, and the relatively high humidity is often very high. Artificial lawn raw materials are commonly known as plastic. Fiber is very simple to reproduce and reproduce algae in the environment with relatively large humidity. If you breed algae, it will make the place very slippery, and simply makes the athletes fall in the movement of the movement. So how to dehumidify has become a major problem for many builders. Decar dehumidification is also an important thing for summer artificial lawn protection!
