Shanghai is Asia Industrial Co., Ltd. artificial turf Description 45 yuan / square meter artificial turf that "artificial turf" lawn name suggests, is a purely human product, different from the natural grass, artificial turf is the PA, PP, PE material pulled into wire grass, and PP woven grass through mesh machine, sew together, and then through the small of the rubber, so that the two complexes together. Is purely artificial products. Artificial turf base can be divided into three basic materials: cement concrete base, asphalt base and foundation Panax dust. Cement concrete foundation 1. Flatness: Flatness pass rate above 95%, 5 m straightedge error 3mm. 2. Applications of artificial grass slope: center field 3 ‰ -4 ‰, Turtle drainage design. Curve 8 ‰, straight 5 ‰, semicircle area 5 ‰, the surface should be flat, smooth, ensure drainage. 3. Strength and Stability: uniform solid surface, no cracks, no bad side seams straight and smooth, about 6000mm × 6000mm cuts as well. Cushion compaction, density greater than 95%, after the mid-sized mill press, no significant wheel tracks, loose topsoil, waves and other phenomena. 4. impermeable layer: new PVC thick impermeable film, lap should be days to 200mm, edge margin greater than 150mm. 5. Maintenance period: Basic maintenance period of 21 days. 6. Positioning: In order to accurately draw a line construction and needs, applications securely distinctive marker marked each line site. Asphalt base 1. Flatness: foundation should have a certain strength and stability, foundation cracks and not the product due to uneven heaving caused by freezing, flatness pass rate above 95%, 3 m straightedge error 3mm. 2. slope: horizontal <1%, vertical <1 ‰, high jump area <4 ‰, the surface should be flat and smooth ensure drainage. 3. The strength and stability: the best use of asphalt base without wax, wax-containing little or bituminous material, which must be fully compacted asphalt mixture. Solid surface evenly, smooth and no cracks, no bad side heap crowded, no pockmarked face, seams are smooth.
