Abroad, most of the artificial turf used by the artificial grass fiber material is high-grade nylon material, but also the use of multifibrous fiber, and no sand artificial turf can also be divided into two kinds of water seepage and non-seepage. This lawn is shaped like a natural lawn, partly with a layer of shock-absorbing foam, and a variety of different densities and thicknesses. As the manufacturers in the country to master the artificial lawn laying technology is not much, and mostly foreign technology, therefore, in the laying of artificial sand lawn is not filled, especially the laying of shock absorber cushion must be completed by foreign experts. Shock-absorbing foam to lay a layer of smooth asphalt under the foundation, asphalt under the gravel, sand and pebbles as a basis, and the structure of the drainage system is the most critical link. In addition, this type of artificial turf must be used in the installation process of artificial grass special machinery, especially in some professional or costly sports venues in the laying of the installation is particularly important, otherwise it will not be able to achieve the site formation and uniformity requirements The In the case of
Filled with granite lawn because of the international advanced level of good sports performance and good practicality in China by the majority of users accepted. Most of its material is made of polyethylene (PE) or polypropylene (PP) more than two kinds of polymer materials, the lawn of the fiber than the sand is not long, the surface backfill 2-3 mm quartz sand and rubber particles. Its sporty characteristics are very close to the natural lawn and can be used all the year round. Usually after the laying of the need for conservation using 6-8 months to achieve the best condition. This type of lawn is particularly suitable for laying outdoors, the warranty period is usually 5-8 years, but its actual life can be more than 5 years. In the long dry weather, as long as the water sprinkled on the lawn, you can reduce the risk of athletes being bruised.
The combination of natural lawns and artificial lawns is no longer a dream, and now has such a mixed lawn, this lawn grass is natural, with plastic on the grass root structure reinforcement, for example, let the grass made of plastic Like the bottom of the growth. In this way, the natural lawn combines the user-friendly characteristics with the superior durability of the artificial turf.
In the domestic filling of artificial artificial turf accounted for 95%, but many schools in the choice of products are often easy to overlook the most important construction links, artificial grass construction technology for artificial grass in the latter part of the maintenance and improve service life is very important.
First of all, to be technically prepared, make a "three links and a flat" and familiar with the drawings, check the basis of construction quality inspection, laying the site to be clean, the surface should be dry, smooth, no debris, no wax, grease, the minimum construction temperature should Keep at above 10 ° C. Use the theodolite or other instruments to measure whether the surrounding facilities are in accordance with the size of the playground. If there is any improper place, please modify the allowable error of ± 5 mm.
Second, before the laying of artificial grass and artificial grass production units to carry out quality inspection of the turf, check the turf material quality, density and weaving process is qualified to meet the requirements. A standard site connection point can not exceed 30, at the same time, check the quality of the filler to meet environmental requirements. In the laying process, to use special tools according to the specifications of the lawn trimming, the seam, the lawn lawn cut. Use artificial grass sports space for special glue connection, seams should not be greater than 2 mm. Bonding temperature can not be too low, the ambient temperature should be selected above 10 ℃ construction is appropriate; the other should not be in the rain or moldy weather construction, otherwise it will lead to too long bonding or even cause non-stick.
Finally, the quartz sand, rubber particles are the most important part of the construction process, only to be artificial lawn surface material installation is completed, check the formation of a solid meet the requirements, before filling quartz sand and rubber particles. Fill specifications and quantities are based on the height and density of the grass. It should be noted that the use of special sandblasting machine and brush grass equipment to fill the particles, can ensure the site flatness and uniformity, while helping to improve the performance of the venue. And quartz sand and rubber particles must be completely dry material can be constructed, otherwise the stems will be overwhelmed and affect the filling quality. Quartz sand should take a multi-layer filling, each filled with a layer of brushers are required to use the brush back and forth to fill the filling full. It is usually better to have a place to go back and forth for more than twenty times.
