What are the advantages of artificial grass?
According to the experience of double and sports turf systems rich, artificial grass cement concrete foundation are introduced: 1, on the basis of the surface smoothness requirements higher, to ensure that the artificial turf surface layer thickness, elastic uniform. Flatness pass rate of 95% or more, 5 meters straight ruler error 3MM, slope: horizontal 8 per thousand, vertical 5 per thousand, semicircle area of 5 per thousand, the surface should be flat, smooth, guarantee drainage. 2, the foundation should have certain strength and stability. 3, uniform surface solid, no crack, no broken edge pits, the seam is smooth, with 6000mm * 6000mm about cuts as well. 4, cushion compaction, compaction degree is greater than 95%, in medium rolling machine pressure after no significant Wheelpath, no dust, loose wave phenomenon. 5, cement foundation must have an impermeable layer, the water barrier adopts new PVC thickening water film, the joint should be greater than 300mm, margin margin is greater than 150mm. 6, need to consider expansion joints, width of 5 mm. 7. The basic maintenance period is 2-3 weeks. (a) is not filled with sand artificial turf in the United States, artificial grass fiber materials used by most artificial turf is high-grade nylon material, also used multiple fibers, without filling sand artificial turf can be divided into two kinds of seepage and seepage. This lawn resembles the natural lawn in appearance, partly with a shock absorbing foam cushion layer, and the shock absorbing layer has a variety of density and thickness.
The artificial lawn has the advantages of bright appearance, green seasons, vivid and good drainage performance, long service life and low maintenance cost. The quality requirements of artificial turf system mainly depend on three aspects: hardness, smoothness and drainage gradient. Artificial grass based commonly used three types: foundation, foundation, cement asphalt macadam base, by which type is mainly caused by the local climate and the budget will use time, temperature and especially suitable for northern winter low temperature climate environment, but also because of its high cost, for a warm and humid environment is not the most the appropriate type of foundation, foundation stone because of its simple construction, low cost, rapid drainage, more common in the south, but because of its rigidity and poor stability, long time use is easy to appear after basic loose, resulting in uneven foundation; therefore, in most areas of China, the cement concrete foundation into artificial grass foundation the type of economical and practical, very high cost.
The artificial lawn is divided into woven base fabric, imitated straw like synthetic fiber, and coated with fixed coating on the back. It is applied to the artificial lawn on the playground, Garden floor and green ground. Its main raw material is polypropylene, and polyvinyl chloride and polyamide can also be used. The leaves are green like grass and add UV absorbers.
