Who will guarantee the quality of the synthetic turf pitch?


Who will guarantee the quality of the synthetic turf pitch?

In November 2006, I reported on a Beijing University of synthetic turf football pitches usage led to some discussion of the synthetic turf industry.

after the use of the synthetic turf pitch, the entire turf system there have been a variety of problems, then who should bear the responsibility? turf suppliers? venue construction contractors? Party?

With this problem, we visited the venue of the relevant class manufacturers and industry experts.

Average data use in Europe in the use of high-strength synthetic turf venues is a very serious problem, a per capita use of an area of 125 square meters, a week of average use time is 60 hours, while in the country and some up to the time of a standard school grounds, almost 400-500 people to use. This incorrect use of the venue, the overload of use, coupled with inadequate grounds maintenance on the synthetic turf stadium now all the circumstances.

Turf system is composed of various parts, all aspects of the mutual influence: the basis of the level of the venue, the quality of the construction, the quality of the turf, the degree of saturation of the filler and the maintenance of late are several key factors that affect the synthetic turf system .

First of all, the basis of the level of the venue is a little attention to the problem. Different location, a different environment is not the same on the basis of the requirements of the venue, this is to ask all construction must have experience in technical processing, standard made of what kind of foundation to ensure longer shop in the above the turf life indeed when many enterprises in the country less construction experience, technical support is not enough, causing some pre no expected problems and lead to more problems. Party is more need to find some large enterprises in a better reputation in the industry, engineering quality standards cooperation is guaranteed venue, we learned that most of the projects abroad in order to guarantee the life and movement of the turf standards, in general the basis of laying elastic cushion layer, but also to meet the flexibility and other requirements of the entire system. we think this is a place worth learning from.

Li Mengta successfully completed in South Africa FIFA project of artificial grass pitches


Li Mengta successfully completed in South Africa FIFA project of artificial grass pitches

    The FIFA Recommended manufacturers Limonta (Li Mengta) has been in South Africa the the Ekangala, Mafikeng and a Tlakgameng community laying three new football pastures. The establishment of the new artificial grass pitch on the children away from troubled neighborhoods in South Africa to make further efforts.

    In Roberto Teani, Li Mengta sports marketing manager said "laying these football pastures from the local community for a huge and important role, because anyone, including schools, clubs, and ordinary people can use these venues." This in South Africa project, company Li Mengta item Bid by a private committee selected suppliers. The construction of three artificial grass pitch is part of the construction of a new artificial grass pitch in the various regions of the country. Three artificial grass pitch points are named: the Ekangala (Ekangala Stadium) Mafikeng (the Mafikeng cities artificial grass pitch) and the the country artificial grass pitch in Tlakgameng (Tlakgameng). Teani said: "In general, artificial grass stadium is located in the suburbs of large cities, rather than the city this all directions more three artificial grass pitch in South Africa in different directions: Ekangala Puleduoli Asia near (Pretoria), Mafikeng in South Africa in Botswana (Botswana) border Tlakgameng northwest.

    Stoning field into a sea of ​​joy

    "Mafikeng" Tswana name meaning "stone place", which indicates the difficulty of this project. And three foot artificial grass pitch in the severely underdeveloped regions. Before the completion of the artificial grass pitch, players of all ages have full play the venue of stone and dust, can not organize any training activities, league or school curriculum - is therefore very important to the successful laying of the artificial grass pitch. Order to ensure the required quality level, the only FIFA Recommended manufacturers, such as Li Mengta nine companies are allowed to bid. The FIFA recommended producers Active made a global commitment to football pasture pasture quality, performance and security based on the needs of the end user, to meet the highest standards. Teani added: "this approach makes the investor of the project will be completed successfully full confidence". FIFA recommended the experience and knowledge of the manufacturer, and provided the necessary technology, is the completion of the project and ensure that the materials used in the protection of the region's climate conditions. "Under normal circumstances, a new artificial grass stadium's construction completed in an average of three to four months time, but in South Africa, including maintenance and paving may need five months.

    Quality and safety

    The final quality of this project is obvious. All three artificial grass pitch FIFA venues Star certification level certification for its outstanding performance and is ideal for everyday use. FIFA venues certification adhere to quality standards, regular inspection experiments and field tests by an independent body recognized by FIFA. Teani summarize positive impact in the laying of the community: "Prior to this, the kids after school activities, and do not know anything about foot artificial grass course description, they only know the bare earth. Now let the kids off the streets towards sufficient artificial grass pitch, participation and football-related activities is not a difficult task. "the Ekangala, Mafikeng Tlakgameng, soccer pasture open six to ten hours a day to the local people, the children in the after school hours can be a convenient and a safe place to play. They can also organize some of the high level of competition, technical guidance and educational activities and a number of other sports organizations. Therefore have to admit that South Africa's foot artificial grass stadium project is more than just a foot artificial grass pitches, football is not just a simple as a game or competition.

the artificial turf Croquet venue requirements


the artificial turf Croquet venue requirements:

Croquet in the projects of the elderly as the main object ball games, venue construction must be based on the physiological characteristics of the elderly, the election in sheltered, sunny, safety and drainage conditions better place with better green as much as possible create a favorable environment for exercise, entertainment, rest.

Croquet Profile
   Croquet is in the ground or on the lawn, strike a ball with a mallet through the iron gate of an outdoor ball games, also known as croquet.
   Croquet originated in France, came after the United Kingdom, Italy, the United States and other countries; introduced to China in the 1930s, and then only as a games lesson content at Yenching University; 1948 gateball the rise in Japan, began in 1970 as the elderly The activities of the project to promote the open.
The gateball is a game, two teams of 10 players each team member each from the ball, independent batting and cooperate with each other sports, has a small footprint, spend Province, simple technology, a small amount of exercise, and security features. Gateball not only simple rules makes it interesting, but also can stimulate the brain and promote physical and mental, is among the most affordable new movement for all ages, suitable for the elderly in physical exercise.

artificial turf croquet rules
   Croquet Rules in turn make the ball through the goal, hit the winning post and finished the race. Game, the two teams each five balls, one red ball, one white ball, alternately from the 1st to the 10th hit red, white ball. 1 ball each team called "self-ball, ball number and team number consistent hitter hit the ball over the serial number when a tee for the first time, the rest of the ball for his ball. Successfully hit the ball over a known hitter through the first door, the player can again batting over two, three, the same is true. In addition, if the ball successfully through the third door skittle, corresponding with the number of the ball players to end the game. The ball, since the ball touched his ball, called the crash. Since the ball and he knocked his ball comes to rest in the competition line, live in self-ball hitter needed a foot, and his ball since the ball abutting, then, since the ball hit ball hammer, the use of impact ball slips out, called Blitz. Whether it is successful batting interlude or blitz, the batsman time continued to strike the right. Order every ball each by a goal to get 1 point skittle 2 minutes to complete the number of game players 5. To the end of the game, each team member added to the resulting scores to determine the outcome, the total score more than the winner.

Croquet venue
   (A) croquet venue requirements by limiting coil fixed, ground flat rectangular, without any obstacle.
   (B) the game line (known as sideline) of 20 to 25 meters long, 15 to 20 meters wide. Edges as a strip, a bandwidth of 1 to 5 cm, the outer edge of the venue of the size to bandwidth prevail.
   (C) limit the same line with the sideline, 0.5 to 1 meter outside the sideline, parallel with the sideline.
   (D) edges, limit lines and other inside line to be clearly visible, the line color of the stadium ground color should be easy to identify conducive observed.

artificial turf Description:
   Venue size, distance between the length and width of the band edges, color, and edges with limit lines are available in the specified range as appropriate.

When artificial turf soccer field installed, needs two weeks time for the solid grass Camp dimensional


When artificial turf soccer field installed, needs two weeks time for the solid grass Camp dimensional, I suggested:

Sporting events should not be held in the near future, the unnecessary transportation vehicles are not to enter the venue, the heavy machinery can not enter the venue,

Not too much in the meantime, cleaning times, twice a week, which can not be cleaned at high temperatures, in the management of attention to the following points:

Keep clean:

Cleaning artificial turf football field to maintain the only effective way of sports venues, and the venues used frequently, once a month to secondary maintenance;

Control the use of the venue:

Organizing competitions, venue to keep more than a week when the maintenance before use. As it allows the next time and enough trash to the garbage leakage;

3. Timely repair the damage:

Spring Festival, when appropriate, on artificial turf maintenance, repair, be sure to carefully check the stitching loose, check Holistic the grass base fabric or without tear, damage phenomenon, should be promptly filled patch;

4 non-smoking venue with food Admission.

artificial turf sports systems based on quality requirements are mainly concentrated in three areas: hardness, flatness and drainage slope. artificial turf appearance of bright green seasons, lively, good drainage performance, long life, low maintenance costs. There are three types of commonly used artificial turf basis: asphalt base, cement foundation, gravel based on what type of main by the environment and the budget of the local climate, the time is determined, asphalt base, especially for a large temperature difference between the north and low winter temperatures, climate and environment, more common in the South, but because of its rigidity and stability, prone to prolonged use foundation loose, resulting in an uneven foundation; also because its expensive for a warm, humid environment is not the most suitable foundation type , gravel base because of its simple construction, low cost, rapid drainage in most regions of the domestic cement concrete foundation became economical and practical, the cost is very high artificial turf base type.

Here we introduce the composition of the artificial lawn.


artificial lawn made of? Here we introduce the composition of the artificial lawn.

1, the grass line-artificial lawn
(1) from the chemical composition is divided into:
Polyethylene (PE): soft, wear-resistant, moderate cost, better overall performance, the public widely accepted.
Polypropylene (PP): grass fibers hard, good elasticity, are generally applicable to the tennis court purposes.
Nylon (PA): soft, good wear resistance, but the price is too expensive, so use the field smaller.
(2) is divided into a line shape from the grass:
Single fiber (straight grass and Juancao of), and reticular fibers (straight grass and Juancao of)
Nouns Notes:
Polypropylene (PP) Basic Formula: CH2 = CH-CH3, with the different degree of polymerization, the material properties will differ.
Polyethylene (PE) Basic Formula: CH2 = CH2, the comparison with the polypropylene, the material is softer and better anti-aging properties.
The basic nylon (Nylon) Formula Material: CONH2, superior performance, and thermal wear-resistant, non-flammable and non-toxic, with good elasticity and recovery properties.
The performance of the grass fibers) nouns Comment:
The wearable ----- material composition
Anti-ultraviolet ----- UV agent
---- Amine anti-aging
The antistatic ---- Antistatic agent (ASA)
Color --- Color Masterbatch
Thermal stability --- recipe

2, the bottom of the artificial turf-artificial lawn
(1) the vulcanization wool PP woven bottom: durable, good corrosion resistance, have good adhesion of the glue and the grass line, easy to securely, the price is high compared with PP woven cloth.
(2) PP woven bottom: general performance and higher cost.
(3) the bottom of the glass fiber: glass fibers and other materials (the bottom of the grid), and to increase the binding force of the bottom of the strength and the grass fibers have excellent help.
(4) PU at the bottom: a strong anti-aging properties, durable; grass lines strong adhesion, and environmental protection is odorless.
(5) woven bottom: woven bottoms do not use underlay, glue directly attached to the fibrous roots, this bottom simplifies the production process, saving raw materials, more importantly, is able to meet the the ordinary artificial turf prohibited sports, such as : javelin, etc., but the bottom of the woven high equipment and process requirements for this type of product not yet appear.
(6) composite bottom: PP cloth + composite structure, low cost, under normal shape better, but the bottom of the tear resistance, moisture resistance less capable, easy to crack, rot;
(7) the bottom of the green: green at the bottom of a change in the artificial turf black tradition, and the introduction of the concept of environmental protection at the bottom, a revolutionary leap in the bottom of the artificial turf.

3, glue-artificial lawn
(1) styrene-butadiene latex: plant material of choice. Good performance, low cost, and with water
Financial, but leaky rubber production equipment and process requirements;
(2) polyurethane glue: strength and binding force is several times the styrene-butadiene latex and foam plastic products
Above, durable, beautiful color. (Foamed polyurethane:
Increase turf flexibility, wear-resistant, the drawback is easy to crack).

The advantages and disadvantages of synthetic grass monofilament and split film mesh wire


The advantages and disadvantages of synthetic grass monofilament and split film mesh wire

synthetic grass


What is a monofilament lawn? What mesh lawns? As two production technology, both of which one is better the controversy has always existed. In fact, many on the other side of the accused is one-sided, commercial. Monofilament synthetic grass durability high wire mesh, which is widely recognized in the industry point of view. However, this point of view a premise mesh wire thickness can not go up. The usual extrusion thickness of the monofilament 0.15mm, while the mesh wire thickness not exceeding 0.11mm. But the emergence of second-generation LSR may change this second generation LSR mesh wire grass has reached maximum thickness 0.15mm. UV-resistant wear-resistant and rebound has greatly improved. Course extruded monofilaments are making progress, the current maximum thickness of more than 0.20mm, but the difference is drastically reduced.

Mesh wire of the biggest advantages of synthetic grass is inclusive of the filler, the monofilament grass filler liquidity strong some mesh wire because of thick wire, there is a connection between the wire and the wire, so stable during use good and less relative displacement between the filaments. The monofilament wire is separated, every blade of grass silk bondage, long-term use in the wire between the relative position will change, which will change the venue of sports performance. In addition, the mesh wire thick wire, the user better foot stability.

Where artificial turf can be used?


Where artificial turf can be used?

artificial turf application: can be applied on the runway, soccer fields, tennis courts, a baseball field, hockey rink, gate ball court, golf course, basketball courts, volleyball courts, badminton courts, softball field and other sports venues. Can also be applied in the Square, the venue of the venue and the primary and secondary schools, kindergartens. As well as road, rail, community greening, roof, courtyard green decorative. The 40-60 millimeters grass is used in universities and official game sites. 25-35 mm grass multi-use with more than 20 mm of the primary and secondary school playground grass tennis courts, hockey field, volleyball court, runway pavement.

Artificial sports turf product characteristics:

A range of applications from the limitations of natural conditions such as rain, snow, and "all-weather sports venues.

Produced using a number of modern science and technology to make our products the tensile strength, firmness, flexibility, abrasion resistance, aging resistance, color fastness all reached a very high level.
Security. The use of the principles of medicine and movement mechanics, movement by movement on the lawn, ligaments, muscles, joints, such as the protection of the fall impact force and friction is greatly reduced.

4. Imitation ecological principles. Foot feeling so that movement in the lawn, the rebound speed of the ball, and very close to natural lawn, and there is good water permeability.

Routine maintenance is very simple, low cost.

The average service life of 10 years or more. Still in use in Europe 20 years ago, laying artificial turf. Stadium crossed production molding white grass seedlings. Are environmentally friendly products, it does not contain any harmful substances, and absorbing noise function.

Plastic tennis courts with artificial turf tennis courts contrast


Plastic tennis courts with artificial turf tennis courts contrast

Plastic tennis courts and artificial turf tennis courts, two tennis courts, and is most commonly used in sports stadiums this article we will be facing the tennis court characterized the comparative analysis.

A plastic tennis court

Plastic tennis courts base layer is a rectangular solid plane, from a polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, a filler composition. Also different due to the different types of materials, characteristics also have a certain degree of difference. The common silicon PU tennis court, tennis courts polyurethane. Plastic tennis courts in general have the following eight characteristics:

A good formation, because it is the basis of requirements has decided it has almost the level of the flat, self-leveling material used in the construction of a flat surface, particularly flat venue to meet requirements;

Good elastic properties, has moderate elasticity and rebound, can reduce the consumption of physical strength, enhance competition results, a big bright spot because the plastic is its elastic properties, using it for the material produced by the stadium naturally have it " traditional ";

Good friction performance, we should be with the car tires in our lives has some common, so it's the friction performance naturally do not have extraordinary;

4 good grip performance, the living in the performance of its formation and its high performance, high speed friction and other characteristics make it a good grip;

Weather wear-resistant compression resistance, impact resistance, will not fade due to UV, ozone, acid rain, pollution, chalking or softening, abrasion resistance is less than 2.5%, not due to the weight and not be able to restore elasticity tough an elastic layer and a buffer layer, can absorb the strong impact, the surface will not be damaged;

6. Antifouling strong, because I wanted the plastic can be said is a foreign almost a "closed" material the stadium use it to produce natural "without doubt";

7. Economy and low maintenance costs, its own protection "do it in place, maintain trouble, is it a manifestation of cost-effective combination of these can be seen;

8 colorful, the dedicated high elastic EPDM and PU particles, surface color, soft, granular surface to prevent the dazzling light reflection, beautiful and durable, and can be multi-color matching.

artificial turf structure is mainly composed of three parts by of wire grass at the bottom and glue


Sports artificial turf structure is mainly composed of three parts by of wire grass at the bottom and glue. Grass silk raw materials used by domestic manufacturers, the main points in both domestic and imported. In general, the the imported turf performance and quality are better than domestic turf, but expensive, are only a few joint venture manufacturers. Many users tend to believe that the good grass silk raw materials we will be able to build a good playground. On this issue, we visited a national standard drafting team, Professor Meng.

Professor Meng pointed out that the and from imported wire grass itself, the performance and quality less point of view but from the construction of a good golf course, is not simply a factor of the raw materials by wire grass decisions. Objectively speaking, the good or bad of an artificial turf pitch is determined by the whole "artificial turf systems engineering.

Raw materials in addition to the turf, the stadium is good or bad by the bottom of the quality of the artificial turf, the technical process of production, the stadium foundation laying process, after-sales service and other decisions.

Therefore, the one-sided pursuit or designated turf is produced by a well-known foreign manufacturers of this view is wrong, and should aspects to consider. At present, domestic manufacturers have been with this strength, the like hockey training field in the 2008 Beijing Olympic Games --- Lu City Sports school grounds, is an artificial by domestic turf joint venture to overcome foreign brands and successful, must rely on the comprehensive strength of the whole "artificial turf systems engineering.

Venue construction process, you can make the right decisions to make the majority of users, the following, I will introduce the important impact of artificial turf venues several important quality aspects:

Standard construction and installation process

Detection, before entering the construction the flatness of foundation, slope and surface perception proposed trimming measures and requirements, to meet the requirements before entering the construction.
