The component structure of the Artificial lawn

1. Chemical ingredients

The raw materials are mostly polyethylene (PE ) And polypropylene ( PP ) Mainly, polyvinyl chloride and polyamide can also be used.The leaves are green with imitation natural grass, and UV absorbers need to be added.

Polyethylene(PE) : The feel is softer, the appearance and sports performance are closer to natural grass, and are widely accepted by users.It is currently the most widely used artificial grass fiber raw material on the market

Polypropylene(PP) : Grass fiber is hard, and is generally suitable for tennis courts, playgrounds, runways or decorations.The abrasion resistance is slightly worse than polyethylene.

nylon(nylon) : It is the earliest artificial grass fiber raw material, which belongs to the first generation of artificial grass fiber.The grass is soft and the feet feel comfortable.

2. Material structure

Artificial lawn3 Composition of layer materials.The foundation layer is composed of consolidating the soil layer, gravel layer and asphalt or concrete layer.The basic layer requires solid, non -deformation, Smooth and impermeable surface, that is, general concrete venues.Due to the large area of the hog stadium, the basic layer must be processed during construction to prevent sinking.If the concrete layer is paved, the expansion seam should be cut out after the concrete is curing to prevent thermal expansion deformation and cracks.

Above the foundation layer is a layer of buffer layer, which is usually composed of rubber or foam plastic.Moderate elasticity of rubber, thickness3 ~ 5mm EssenceThe cost of foam plastic is low, but poor elasticity and thickness 5 ~ 10mm The thick lawn is too soft and prone to depression; too thin and elasticity can not play a buffer effect.The buffer layer should be firmly pasted on the basic layer, and generally paste with white latex or universal glue.

The third layer is also the surface layer.The surface shapes are fluffy grass, rings curly nylon silk garries, leaf -shaped polypropylene fiber garries, and water -based water -based gargams prepared.This layer must also be glued on rubber or foam plastic with latex.It must be fully applied during construction, and it must be sticked in sequence, and cannot be wrinkled.

In foreign countries, there are two common types of grass cortex:1 The leaf -shaped fiber of the gargams is thin, only 1.2 ~ 1.5mm Items 2 The grass fiber is thicker, 20 ~ 24mm It is filled with quartz on the top of the fiber.

What is the material of the Artificial lawn

With the development of the market, artificial grass has changed greatly in terms of materials, technology, construction and other aspects. The purpose of these changes is to make artificial grass closer to natural grass in terms of sports performance, which can be divided into the following stages.The

The first stage: mainly nylon materials, like a Carpet, poor elasticity, no protection for athletes, easy to be injured;

The second stage:PP Materials are the main, and the quartz sand particles are filled in, and the hardness is high;

Third stage:PE Materials are the main, fill in quartz sand, and fill in rubber particles at the same time, with the elasticity of natural grass, and the exercise performance is greatly improved;

The fourth stage: Taking the FIFA certification as the standard, focusing on the construction of system projects such as foundation, construction, etc. In addition to mesh products, direct mixed products and other products have appeared.PE and PP mix, PE Mix with nylon, further strengthen exercise performance;

Fifth stage: mainly single -silk grass, in addition to pursuing sports performance, but also pursue a more ideal appearance, while paying more attention to the construction of the system;

Sixth stage: mainly curl grass, a specialty grass, golf and other artificial grass.

Temporarily mature technology development in the fourth stage and fifth stage in the market.
