Nowadays, artificial turf has penetrated into people's lives. The reason why artificial turf can be widely accepted and applied is because it is more abrasion-resistant, weather-resistant, easy to maintain, elastic and color stable than natural grass/planted grass. Therefore, people are paying more and more attention to the environmental performance of artificial turf in actual use. At present, the testing of the environmental performance of artificial turf has become an indispensable reference for evaluating the quality of artificial turf. So, what are the important evaluation indicators for the environmental performance of artificial turf?
First, the classification of environmental performance indicators of people on lawns
Heavy metals: lead, cadmium, chromium, mercury, arsenic
Toxic chemicals: benzene, toluene and xylene, free toluene diisocyanate (TDI), TVOC, polycyclic aromatic hydrocarbons (PAHs)
Second, the evaluation index and testing purpose of the environmental safety performance of artificial turf
1. Heavy metal content
Heavy metals such as lead, mercury, arsenic, and cadmium are toxic substances, and their content testing is used to assess whether the lawn itself is safe and environmentally friendly.
2. The content of other toxic and harmful substances
The detection of relevant toxic substances is used to evaluate whether artificial turf and auxiliary materials exceed safety standards.
3. The release rate of toxic and harmful substances
Chemicals are volatile. This indicator is used to evaluate whether the evaporation rate of chemicals contained in artificial turf and auxiliary materials exceeds safety standards.
Third, artificial turf environmental performance testing standards
Domestic: National standard GB/T20394-2013 for artificial grass for sports, Shanghai Youth League Committee standard T/1310101002-C003-2016 Limit of harmful substances on the surface layer of plastic running track of school sports venue, Shenzhen standard SJG29-2016 quality control standard for surface layer of synthetic sports field.
It should be emphasized that at present, people around the world are paying more and more attention to the harm of environmental pollution to the human body, and the volatilization of harmful substances in inferior artificial turf will cause harm to the human body and pollute the environment. The human body will be in close contact with artificial turf every day, and only artificial turf with good environmental protection performance can protect human health to the greatest extent.
