Many football field artificial turf laying

Many football field artificial turf laying, but the laying of artificial turf football field require other materials such as quartz sand, black rubber particles, then the ratio of the number of different wire grass is what it?

Quartz sand to be poured into the grass, since the foundation of the grass to protect, to counterweight and prevent the effects of aging of the deep grass silk. Specifications of quartz sand is generally in the 20-40 mesh; rubber particles can play to enhance flexibility, improve the degree of simulation, to protect the athlete's role, generally used for more than 32 mm of Artificial Turf, specifications for the 1.5-mm. The sprinkle irrigation quartz sand, quartz sand need to sprinkle a layer with a nylon brush to push up the grass, Zaisa layer, until the grass evenly exposed a suitable height.

     artificial turf filled with quartz sand and rubber granules dosage recommended:
     The length of the wire grass filled with quartz charge the amount of rubber particles fill the top of the wire grass height
     10mm approximately 4-8 kg / m without charge rubber particles of about 5 mm
     20mm approximately 8-20 kg / m about 1-2 kg / m approximately 7 mm
     25mm approximately 15-20 kg / m about 1-3 kg / m approximately 8 mm
     32mm approximately 18-23 kg / m approximately 2-3.5 kg / m 9 mm
     40mm approximately 23-28 kg / m about 3-5 kg ​​/ m approximately 13 mm
     50mm approximately 28-32 kg / m about 5-6 kg / m approximately 17 mm
     55mm approximately 32-35 kg / m about 5-7 kg / m approximately 19 mm
     60mm approximately 35-38 kg / m about 6-8 kg / m approximately 20 mm
   
2 adhesive cloth: the role of the adhesive tape is to be connected together the lawn and boundaries of the entire site. There are two types: a width of 20-25 cm for the bonding between the lawn and the lawn; width of 25-30 cm is used for bonding between artificial turf and white lines. To a standard football field, for example: the adhesive tape is about 3000 meters.

Glue: Artificial Turf for bonding, adhesive cloth with plastic about 0.3 kg per meter.

4 grass loss: a regular venue, grass attrition rate of about 3%, the runway corners loss rate is about 8%.

Lawn grass is artificial planting herbaceous vegetation management with aesthetic and practical function.

Turfgrass use and adaptability of

Lawn grass is artificial planting herbaceous vegetation management with aesthetic and practical function. Green grass in the park, manicured golf courses and functional sports turf, can give people the joy of beauty. In addition to the aesthetic function, lawn grass also has the function of cleaning up the environment. Per acre lawn can absorb hundreds of thousands of kilograms of sulfur dioxide, provide oxygen to the atmosphere (photosynthesis). A small courtyard green manufactured oxygen enough a normal use.

The turfgrass is divided into cool-season and warm season turfgrasses two categories. Due to the different photosynthetic pathways, cool-season and warm-season turfgrass were classified as C3 and C4 plants. The following brief overview of several major turfgrass:

Cool-season turfgrass:

Kentucky bluegrass (Poa pratensis L.) can be applied to the courtyard lawn, green parks, golf courses and other sports turf planting. It is usually applied in moderate to high level of conservation management. The main floor space for seeding or the turf floor space. Floor space by seed, germination generally takes 10-14 days (to be slower than most lawn grass), the floor space is also very slow speed. Advantage of the grass with stretch ability rhizome, long life cycle, ability to adapt to the environment, resistant to trampling (commonly used in the sports arena), and better than other cool-season turfgrass resistance to heat, drought and cold characteristics. In addition, some Kentucky bluegrass strong shade tolerance.

Canada bluegrass (Poa compressa L.) applicable in lawn quality requirements, and extensive management lawn. Its high top growing point, mowing can lead to injury. It is not easy to form a dense, high-quality lawn, but adapted to acidic, dry, barren soil, so the soil is commonly used on both sides of the highway is fixed.

Ordinary bluegrass (Poa trivialis) pale green leaves, plants and Kentucky bluegrass is small compared. It may be formed in a shaded, humid environment of high density lawn. Heat, drought tolerance, and thus commonly used in bermudagrass greens winter sowing.

has been preferred filler particles of the synthetic grass

This work is inherent in the synthetic grass with discarded tires filled with particles containing carcinogenic PAHs, with a pungent odor, heat absorption, it is difficult to recycle, a single color, and the lawn system compatibility defects and poor, the combination of polymer and professional knowledge, the choice of SBS, SEBS, PP, POE, PE, naphthenic oil, consisting of a thermoplastic elastomer as the matrix, active calcium carbonate, stearic acid or coupling agent treatment to the filled material, together with various pigments and anti- old, etc., as appropriate mixing granulation process, development environment-friendly the new thermoplastic rubber filler particles, making it both environmental protection, wear-resistant, high-elastic, soft, anti-aging, rich colors, thermoplastic recyclable and more kinds of innovation, and applied for national invention patent.

Over the years, the the black scrap tires filled with particles resistant, inexpensive, has been preferred filler particles of the synthetic grass, but in recent years, for such particles containing carcinogenic polycyclic aromatic hydrocarbons (PAHs), irritating odor, smoke high heat, thermosetting difficult to recycling and other shortcomings, many countries and regions have banned or restricted the use of such filler particles. The research group for this trend, the choice of SBS, SEBS, PP, POE, PE, naphthenic oil, a thermoplastic elastomer composition as the substrate, stearic acid or the activity of the coupling agent-treated calcium carbonate as a filler, and then with various pigments and anti-aging agent, a suitable mixing granulation process, to develop environment-friendly new thermoplastic rubber filler particles, making it both environmental protection, wear-resistant, high elastic, soft, anti-aging, color rich thermoplastic recyclable and other features, and applied for national invention patent (200910029870.0) to fill gaps in the type of product. By the new investigation addition to commissioned achievements into a rubber Materials Co., Ltd., there is no domestic production of the types of particles, publicly reported or apply for a patent, formula used in the present invention and innovation has not been disclosed in the literature reported.

Monofilament artificial grass

Monofilament artificial grass

Review the course of development of artificial grass and now has more than forty years, it is the most from the United States, with the continuous development of market demand, in addition to the pursuit of excellence in sports performance, people also want to artificial grass is more beautiful, more practical, lasting. Response to market demand, monofilament grass developed into a trend, as opposed to the traditional fiber grass, it Resembling natural grass, pavement easier, easier maintenance and longer life.

Monofilament artificial grass, once launched, once in Europe and the United States is very popular abroad, 80% of the sports venues are made of monofilament grass, the monofilament grass closer to natural grass, better sports performance, easy maintenance and so on. Domestic, however, is limited due to technical previously monofilament grass mean slice monofilament grass family, it uses the traditional slice monofilament, due to the constraints of the equipment and technology level and other factors, at the end of its life, the binding force, abrasion resistance and other obvious flaws, resulting monofilament grass in China have not been used by the user.

Choice of golf course putting green artificial lawn

Choice of golf course putting green artificial lawn

Golf course putting green turf generally circular or approximately circular irregular shape, the general area of ​​450 to 700m2. A standard golf course putting green area in the the 0.8 to 1.2hm2. Putting green lawn manicured short grass lawn and generally slight slope and downs, but the ball unimpeded rolling on its surface. Putting green hole position change. Hole puncher by specialized set inside the cave is a metal or plastic cup, the cup should be below ground 2.5cm (1 inch) inside the cave, flags hole, deep 10.16cm (4 inches). So that flag to identify the hole, the hole diameter of 10.79cm (4 1/4 inches).

Rootzones structure:
In 1960, the United States Golf Association (USGA) and the golf course lawn experts recommend a better putting green floor bed structure: Ping bed layer of a 30cm fine sand and peat, below 5.1cm coarse sand, and then the following is 10.2cm thick gravel, gravel under the drain, soil pH from 6.0 to 6.5.

Putting green grasses select:
The bentgrass (north temperate, boreal, cold temperate) Penncross varieties most widely
Bermudagrass (tropical, subtropical and temperate South)
The seashore paspalum improved varieties (tropical and subtropical)
Tropical and subtropical ryegrass for winter overseeding
Ring (Collar) and guards (APRON)

Around the green circle width of 0.9 to 2.7m ring (Collar) (ring lawn mowing height slightly higher than the green and below the fairway) surrounded by protection with the greens, grass and conservation management and greens are the same. Connected to the ring outside the fairway that is connected to the junction of the greens and fairways guards (APRON), management level lower than the greens and fairways similar.

About on artificial grass recycling tire filler concern

One of the advantages of artificial grass is that it is the solution used tires recycling a way, because every year there are more than one billion tires to sell, how to deal with used tires is indeed a problem. Doyle said that the recovery of used tires each year 300 million artificial grass enterprises can take advantage of the 12 points. Laying density of about 4 to 15 pounds per square foot filler, every soccer field to use an average of 20,007 thousand tires made of rubber particles. Europe has begun a massive tire recycling campaign, in this campaign, the tires will meet the quality standards are processed again and utilization. Really can not re-use waste tires are recycled for other uses, including industrial power generation, production of plastic road surfacing materials, and recycling for the automotive industry raw materials for the production of artificial grass. In Western Europe, the recovery of used tires utilization increased from 65% in 2001 to nearly 90% in 2005. Many places in terms of waste tire just a year can increase the number of tons of waste that need to be addressed, but in Europe, scrap tires has become potentially valuable secondary raw materials.

The world's largest tire manufacturers in the world - Michelin - waste tire recycling department SergeP alard. Said: "(discarded tires) uses more and more. Few years ago, in some countries, people do not know how to deal with the waste tires; waste tires can meet the production needs of the provider. "industrial chemicals to follow the requirements of the European Union has recently performed more testing of chemicals registration, evaluation, licensing and restrictions (Registration, Evaluation, Authorisation and Restriction of Chemicals, REACH) regulatory requirements, such as Michelin, the company is working to reduce the use of hazardous chemicals in tires, waste tires in order to facilitate re-recycled as other products. About on artificial grass recycling tire filler concern, European companies are also looking for new and innovative ways. For example, Italy is trying to artificial Grass launched in the market with new non-toxic thermoplastic material as a filler. A flooring manufacturer the Ecofill of production by Mondo is a patented technology polyolefin particles, dedicated to artificial grass. The company claims that this material is more effective heat dissipation, a high degree of damping, PVC-free, ethylene, plasticizers, heavy metals or other harmful chemicals, and 100% recyclable.

Another alternative is made from plant-derived material filler. GEO SAF e Play artificial grass manufacturer the Li Mengta movement its production is a coconut shell and a filler made of cork. Domenic Carapella, a company spokesman said: "There must be an alternative method of the rubber particles and we will no longer justified, more importantly, because of the use of artificial grass at the expense of the quality of movement is no longer reason to harm children's health."

specifications and types of synthetic turf

specifications and types of synthetic turf, if you want the selected type of product, you must have the following indicators can complete description of the requirements:

1, wire grass Material Type: PA (nylon), PP (polypropylene), PE (polyethylene)

Most lawn now use the main material for the PE wire grass, PA wear resistance, but the material is too hard, easy to burn the skin of the athletes, the wear resistance of PP the venue short life, while the PE soft and wear resistance better, is now the venue of choice for sports contact class, the PA mainly used in landscape grass market.

2, the shape of the wire grass: mesh split film yarn, monofilament

Mesh wire in many venues on a large number of results, monofilament became popular in recent years, mainly due to Synthetic turf appearance more like natural grass, beautiful appearance, a slight advantage in terms of wear resistance, but usually high price in the mesh.

3, lawn height: 60mm, the height of the U.S. and European markets usually football stadium domestic venues tender due to the long-standing habits height is generally between 40-55mm, lawn height is higher, the higher the cost, the filling materials and labor costs will also increase, generally around 50mm to meet the requirements of owners can be set to 60mm high grass.

Base fabric adhesive way: usually gum styrene-butadiene latex, more high-end adhesive PU adhesive, the difference between the PU adhesive wire grass pull-off force far greater performance than styrene-butadiene latex, the appearance of bright, waterproof performance is good, because molding PU gum, additives, and so more environmentally friendly. However, the high cost of the PU adhesive, the usually product prices will be higher than the 20% -30% of the styrene-butadiene latex products.

Synthetic Turf base fabric type: usually divided into the base fabric composite base fabric and composite grid three, three relatively higher tensile strength of the base fabric.

6 needles way: usually divided into word needles, and Z words needles. Two needles are used to meet the requirements, but the Z-shaped needles so that a more uniform distribution of grass wire and wire grass gum adhesion will be higher.

, The density of the synthetic Turf: usually 50mm high grass, about 10,000 needles, high quality requirements, can provide appropriate density, but the cost will rise. And the higher the altitude, the General Settings density down.

The 8 grass wire pound: usually divided into 6600DTEX, 8800 DTEX, 9700DTEX, 12000DTEX, 15000DTEX etc., represented Silkwood weight per million meters of grass, usually football venue more than 8800DTEX of.

Pound higher density will be smaller, the basic guarantee in the wire grass per square meter weight of 1 kg.

Synthetic turf industry in China developed rapidly, lawn companies are involved in competitive global markets, we will continue to work in the field of view of the user's perspective and researchers continue to observe the Synthetic turf industry, continue to do the development of sports industry observer.
