According to the production process, artificial turf is divided into injection-molded artificial turf and woven artificial turf.
The injection molding artificial turf adopts the injection molding process, which extrudes the plastic particles in the mold at once, and uses the bending technique to bend the lawn, so that the grass blades are arranged at equal intervals and in equal amounts, and the height of the grass blades is completely unified. It is suitable for kindergartens, sports fields, balconies, greening, sand gold, etc.
The raw materials of artificial turf are mostly polyethylene (PE) and polypropylene (PP), but also polyvinyl chloride and polyamide. The leaves are green with imitation of natural grass and need to be added with UV absorber.
Composition of artificial turf
1. Chemical composition
The raw materials are mostly polyethylene (PE) and polypropylene (PP), but also PVC and polyamide. The leaves are green with imitation of natural grass and need to be added with UV absorber.
Polyethylene (PE): It has a softer feel, closer to natural grass and sports performance, and is widely accepted by users. It is the most widely used artificial grass fiber raw material on the market
Polypropylene (PP): The grass fiber is relatively hard, and is generally suitable for tennis courts, playgrounds, runways or decorations. The wear resistance is slightly worse than polyethylene.
Nylon: It is the earliest raw material of artificial grass fiber and belongs to the first generation of artificial grass fiber. The grass is soft and comfortable.
2. Material structure
The artificial turf consists of 3 layers of materials. The base layer is composed of a compacted soil layer, a crushed stone layer and an asphalt or concrete layer. The foundation layer needs to be solid, non-deformable, smooth and impervious to the surface, that is, a general concrete site. Due to the large area of the hockey field, the foundation layer must be properly handled during construction to prevent subsidence. If the concrete layer is paved, expansion joints should be cut after the concrete is cured to prevent thermal expansion deformation and cracks.
Above the base layer is a buffer layer, usually composed of rubber or foam. The rubber elasticity is moderate and the thickness is 3~5mm. The cost of using foam is low, but the elasticity is poor, the thickness is 5~10mm, too thick lawn is too soft, and it is easy to sag; too thin and lack of elasticity, can not play a buffer role. The buffer layer should be firmly pasted on the base layer, generally with white latex or all-purpose adhesive.
The third layer, also the surface layer, is the turf layer. According to the manufactured surface shape, there are downy turf, circular curled nylon silk turf, leaf-shaped polypropylene fiber turf, nylon woven permeable turf, etc. This layer must also be glued to rubber or foam with latex. It must be fully glued during construction, and pressed tightly in sequence, without wrinkling.
In foreign countries, there are two common types of turf layer: 1. The leaf-shaped fibers of the turf layer are thin, only 1.2~1.5mm; 2. The turf fibers are thick, 20~24mm, which are filled with quartz almost to the top of the fiber.
