the synthetic turf Quality inspection standards

Technical requirements of the test project
The appearance of the surface is relatively flat, no significant uneven Synthetic turf density is uniform, uniform color.
Test of resistance to sulfuric acid at a concentration of 80% sulfuric acid soak for 72 hours, turf no change in color, no abnormal Underlying.
Resistant to gasoline test turf in 90 gasoline soaked for 4 hours, no change in color, the underlying aging.
