Chemical composition and material structure of artificial turf

- Sep 15, 2018-

In the process of making artificial turf, it is mainly effective to make the grass-like synthetic fiber, which is effectively implanted to the woven machine to a certain extent, and the back surface of the artificial turf will be fixed. The coated natural chemical properties of the grass are widely used in sports and leisure places when operating.

Chemical composition of artificial turf
In the process of making artificial turf, the raw materials are mostly polyethylene and polypropylene, and polyvinyl chloride and polyamide can be effectively used in the operation. The leaves are green with natural grass and need to add UV absorber.

If the artificial turf adopts its polyethylene, its hand feel will be softer during the operation. The appearance and sports performance of the whole product is closer to that of natural grass, which is widely accepted by users. This kind of product is the most widely used man-made on the market. Grass fiber raw materials.

If the artificial turf is made of polypropylene, the grass fiber is relatively hard during the production process, and is generally suitable for use in tennis courts, runways, playgrounds or decorations. Abrasion resistance is slightly worse than polyethylene.
Nylon is the first raw material for artificial grass fiber and belongs to the first generation of artificial grass fiber.

Material structure of artificial turf

In the process of making artificial turf, there are mainly 3 materials that can be composed. To a certain extent, the base layer is mainly composed of turf soil layer, asphalt, concrete layer, gravel layer and other rangers. Requires solid, impervious, non-deformable and smooth surfaces. That is, the 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.

Above the base layer of the artificial turf is a layer of cushioning, usually rubber or foam.
The foam used in the product is low in cost, but the elasticity is poor, the thickness is 5~10mm, the thick lawn is too soft, and it is easy to be sunken; too thin and lack of elasticity, can not play the buffering effect. The buffer layer should be firmly adhered to the base layer, and it is usually pasted with white latex or universal adhesive.
