Some synthetic grass design of drainage systems, lawn permeable cushion

synthetic grass is plastic fiber products as raw materials, the use of artificial methods produced "fake grass", compared to natural grass, synthetic grass has unique characteristics, braided nylon woven grass, finished into a blanket. Fascicles with inlaid turf compared to woven synthetic grass production procedures are complicated and relatively expensive lawn surface hardness, buffer performance is not good, but the lawn is good, strong and durable, ideal for tennis, hockey, lawn bowling movement. Mosaic lawn lawn with braided compared leaf fiber length longer and larger changes, and can be adjusted according to specific needs. The grass filled quartz sand, rubber granules or a mixture of both, etc. Appearance performance is closer to natural grass, indoor and outdoor installation, suitable for soccer, football, baseball and so on.

production of synthetic grass synthetic grass choice of materials and the production of materials in general, there are two: polypropylene and polyethylene. PP material for synthetic grass solid buffer force is smaller, generally applies to smaller impact sports such as tennis. PE materials and synthetic grass is soft, cushioning, good performance, the athlete's harmful effects, suitable for larger impact sports such as football, rugby and so on. Mixing two materials may be produced synthetic grass, so the advantages of both can be integrated to meet the special needs of competition. For some high-intensity sports competitions, in order to improve the quality and minimize competition injuries of athletes, the choice of synthetic grass, generally to choose comparatively high fiber material, but also to select PEsynthetic grass or PE / PP synthetic grass hybrid material.

Some synthetic grass design of drainage systems, lawn permeable cushion, the base layer in the design of drainage channels, the construction of such a structure is more complex lawn, a higher cost. However, some systems did not design the drainage system, it would have to rely on the natural slope of the surface drainage, and therefore require a higher surface construction. Before the construction of the synthetic grass, turf quality and economy in order to ensure effective, these four factors should be the main consideration. In addition to these four main factors, there are other factors such as primary treatment, bonding adhesive for selection. Construction of synthetic grass playground, in the choice of synthetic grass height, the general court to consider the overall budget, synthetic grass, height relatively high synthetic grass, their construction and maintenance cost is also relatively high, many schools in Europe often choose the high ground lawn of 19mm, 25 ~ 32mm height completely synthetic grass playing field can provide a high-quality, and some of the synthetic grass sports professional usually high at 50 ~ 55mm, the height generally considered ideal synthetic grass limit.

With synthetic grass manufacturing process matures, its basic manufacturing relative has been perfect, so in the past in order to stabilize the sand filled turf practice has gradually been eliminated, now filled with more ways to use 100% rubber particles. Filled sand or rubber particles are mostly medium-sized, and in filling it before the wash. For some larger impact strength sports such as football, soccer, etc., should be appropriately increased the proportion of rubber particles to minimize the athlete's injury. Impact strength for those small or no impact action, such as tennis courts, sports fields, as long as the space can be homogeneous hardness, less demanding of the buffer, so the choice of the filling material larger room. Depth filled synthetic grass or rubber particles of quartz sand filling depth selected according to the purpose and the lawn of the high beam.
