Nowadays, artificial lawn has penetrated into people's lives. The reason why artificial lawn can be widely accepted and applied is that it is more wear-resistant, weather-resistant, easy to maintain and has better elasticity and color stability than natural grass. Therefore, people pay more attention to the environmental protection performance of artificial grass in practical use. At present, the detection of the environmental performance of artificial lawn has become an indispensable and important reference for evaluating the quality of artificial lawn. Then, what are the important evaluation indicators of the environmental performance of artificial lawn? Let's get to know them together.
I. Classification of Indicators of Environmental Protection Performance of Man on Lawn
Heavy metals: lead, cadmium, chromium, mercury, arsenic
Toxic and harmful chemicals: benzene, toluene and xylene, free toluene diisocyanate (TDI), TVOC, polycyclic aromatic hydrocarbons (PAHs)
2. Evaluation Index and Detection Purpose of Environmental Protection and Safety Performance of Artificial Lawn
(1) Heavy metal content
Lead, mercury, arsenic, cadmium and other heavy metals are toxic substances. Their content detection is used to assess whether the lawn itself is safe and environmentally friendly.
(2) Content of other toxic and harmful substances
The detection of related toxic substances is used to evaluate whether artificial lawn and accessories exceed safety standards.
(3) Release rate of toxic and harmful substances
Chemical substances are volatile. This index is used to evaluate whether the volatilization rate of chemical substances in artificial lawn and accessories exceeds the safety standard.
