Artificial turf football field specifications

I. Artificial turf football field fiber material specifications?

The grass of artificial turf is composed of filaments, the main component of which is polyethylene or polypropylene. Polyethylene made of silk is soft and expensive.

For artificial turf fiber, there are two indicators to control, one is the number of turns, and the other is the fiber diameter. The common parameters are 5700 dtex, 6600 dtex, 7600 dtex, 8800 dtex and 10000 dtex. It shows that the more turns, the finer the grass hair, the better the quality. The fiber diameter is generally between 50 and 150 um. The larger the fiber diameter, the better. Because of the large diameter, the athlete feels thick and resistant to abrasion, whereas the small diameter is not resistant to wear.

Due to the inconvenience of the fiber diameter test, it can also be measured by weight to ensure the fineness of the fiber.

The density of grass seedlings is measured in terms of two aspects. First, what is the number of cluster heads per grass species? The football field should be 130 to 200 cluster heads. The more cluster heads, the better. The second is the woven distance, which is generally 5~10mm. The closer the distance, the better.

These two indicators are expressed as follows: two digits first indicate the length of grass seedlings (unit: mm) with two digits behind, indicating the number of cluster heads (per unit) per 10 cm long.

What is the specification of artificial turf packing?

There are two types of artificial turf fillers: quartz sand and black rubber.

The black rubber particles are broken from the old automobile tires, and the particle size requirement is less than 2~0.315mm. However, black powder less than 0.315mm is not allowed. The black colloidal particles must not contain other substances. More must not use substitutes, such as black rubber, waste wire and so on.

Quartz sand, the largest particles should not exceed 2mm, the smallest particles of 0.315mm, less than 0.315mm particle content should not be more than 5%, compressive strength greater than 80MPa. Quartz sand can not be mixed with any impurity items, such as soil, broken wood, glass and so on.

Filling materials should not be replaced by river sand or sea sand, and stone powder should not be used to avoid affecting athletes' health.

Third, what is the specification of artificial slop floor insulation?

Under the artificial turf, there is a layer of insulation layer, and the material is often made of geotextiles or non-woven fabrics. However, when designing the artificial turf, the isolation layer may not be provided when the vibration layer is added or reduced. The main function of the isolation layer is The artificial turf is prevented from directly contacting with the base surface layer (cement concrete and asphalt concrete), and the exposed artificial turf fiber yarn is worn and broken, so that the grass fiber filament is detached and the service life of the lawn is affected. However, when the artificial turf base mat is good, such as five to six layers, when the outer layer material does not show off grass fiber products, it may not be provided with a separating layer.
