Artificial turf by three layers of materials. Base layer is made of compacted soil, gravel and asphalt or concrete layer. Requires a solid base layer, deformation, surface smooth and impermeable, namely general concrete venue. Due to the large area hockey venue, must handle the construction of the base layer to prevent subsidence. If laying concrete layer rubber track material, after curing concrete expansion joints to be cut out, to prevent thermal expansion deformation and fracture. Above the base layer is a buffer layer, usually composed of rubber or foam. Rubber elastic medium, thickness 3 ~ 5mm. Foam with a lower cost, but poor flexibility plastic runway material prices, the thickness of 5 ~ 10mm, thick lawn is too soft, and easy to depression; lack of elasticity is too thin, would not achieve the buffer. The buffer layer must be firmly attached to the base layer of the runway material, general purpose adhesive with white latex or paste. The emergence of artificial turf stadium can be traced back to the sixties. They are plastic runway material invention in a US military project to improve urban teenager's body. It is called "astro turf", which quickly became an affordable, durable and low maintenance turf maintenance of natural alternatives, and quickly applied to American football, baseball and soccer stadium. With football, tennis, golf and other sports professional, industrial, commercial development makes the development of sport artificial turf industry has made some progress in recent years. Full plastic runway Scope: All schools and professional sports. Track and field track, jump Road, semicircular area. Activities Auxiliary Area venues; non-professional game with basketball courts, volleyball courts, badminton courts and other courts; fitness path, indoor stadium training track, playgrounds and paved roads and so on. Runway characteristics: 1. all-weather use: any season and temperature, can maintain a high standard of quality rain more immediate use, increased use of time. Improve space utilization. 2. Flexibility: having moderate elasticity and rebound. Can reduce physical consumption. Promote competition results. 3. The impact absorption: Moderate absorb foot impact. Reduce injuries, are suitable for long-term training and competitions. 4. Weather resistance: not because ultraviolet light, smelly itchy, acid rain, pollution and fading, chalking or softening. And long-term to maintain their bright colors. 5. Wear: wear resistance of less than 2.5%. Meet all levels of school for a long time. High frequency of use needs. 6. compression resistance: not because of the weight of track and field equipment can not restore elasticity. 7. Anti-nail force: maximum force in the most frequently used one hundred meters starting point, it will not be spikes or starting frame damage. 8. Impact resistance: a tough elastic layer and the buffer layer. Can absorb strong impact, the surface will not be damaged. 9. flatness: Use self-leveling construction material, flat surface, can meet the special requirements of a flat playing field. 10. adhesion: Special construction treatment, strong bonding, can suppress the rising water, no blistering, peeling and other phenomena. 11. Security: to prevent fall injuries occurred. 12. Economy: easy maintenance, saving management costs. 13. Color: special highly elastic EPDM and Pu particles, surface color and soft. Granular surface, preventing reflection glare light. Beautiful and durable. And multi-color matching.
