The commercial lawn is mainly used to embed the grass-like synthetic fiber on the woven base fabric, and the back is coated with a chemical product having natural grass motion performance as a fixed coating. Widely used in sports and leisure venues.
Chemical composition of commercial lawn
Most of the raw materials are polyethylene (PE) and polypropylene (PP), and polyvinyl chloride and polyamide can also be used. The leaves are green with natural grass and need to add UV absorber.
Polyethylene (PE): It is softer in hand, and its appearance and sports performance are closer to natural grass, which is widely accepted by users. It is currently the most widely used artificial grass fiber raw material on the market.
Polypropylene (PP): The grass fiber is hard and is generally suitable for tennis courts, playgrounds, runways or decorations. Abrasion resistance is slightly worse than polyethylene.
Nylon: It is the earliest artificial grass fiber raw material and belongs to the first generation of artificial grass fiber.
Material structure of commercial lawn:
The commercial lawn consists of 3 layers of material. The foundation layer consists of a compacted soil layer, a gravel layer and an asphalt or concrete layer. The foundation layer is required to be solid, non-deformable, and the surface is smooth and impervious to water, which is a general concrete site. Due to the large area of the hockey field, the foundation layer must be handled during construction to prevent subsidence. If the concrete layer is laid, the expansion joint is cut after the concrete is solidified to prevent thermal expansion deformation and cracks.
