anti-ultraviolet stability of artificial grass

anti-ultraviolet stability of artificial grass

Is well known, plastic (for the artificial grass is a polyolefin), under the exposure to sunlight is relatively easy degradable. Such degradation is usually known as photodegradation. The photodegradable process will destroy these products in the polymer chain, and ultimately lead to cracking of the artificial grass blades, chalking, fading and the physical properties of deletion. The artificial grass life of its anti-ultraviolet stability, the end-user to use the strength and density, as well as closely related to the basic and necessary maintenance. Strength and density as well as maintenance of all users to decide, and related to the artificial grass quality of the product itself is UV stability. In fact, adding a certain percentage of the polymer stabilizers can effectively avoid the intensification of the circulation chain reaction, did not add stabilizer or incorrect Proportion, will affect the service life of the artificial grass. R & D and production departments of TurfSoccer very focused UV resistance and stability of the TurfSoccer the branded artificial grass fibers, which is its equal strength longer life and sports performance better one of the important reasons.

Invisible ultraviolet (UV) radiation is the main culprit of the polymer photodegradation. UV is characterized by a very short wavelength, less than 5% in the daylight. The sun's ultraviolet radiation spectrum is divided into UVA, UVB and UVC. 98% of UVA can reach the surface, while most of the UVB and UVC were absorbed atmospheric ozone. Only a small part of the UVB can still reach the surface. However, due to the very short wavelength of the UVB-, in the light degradation process of the polymer of the radiation than UVA lot stronger.

To detect polymer outdoor anti UV stability, the most direct way is the polymer being exposed to the natural climate, but this method is too time-consuming. The climate test method to accelerate the test results by the artificial light source came into being, these methods are used to predict the the anti UV stability after a product has undergone a number of years lifespan. Overall, three artificial weather light source can be used to accelerate climate test: UVA, UVB and xenon.
