Note 1: The selection of heavy metals and other standards
The environmentally friendly grasses use new high-quality olefin polymers, and are not included. The high-temperature resistant color masterbatch and processing aid of heavy metal are extruded and formed at one time. It will not cause irritation to the skin during use and will not cause harm to the environment. The artificial grass and grass are all tested by heavy metals and pass the 19 items of European children's toys. Heavy metal detection. Most of the non-environmental factors of grasses are derived from the use of recycled materials that are unknown or unqualified, because the sources of recycled materials are generally complex and contain many different additives. These additives are easy to use after multiple processing. The reaction or cracking occurs on the one hand, and the toxic and harmful substances are integrated with the grass, which is harmful to the human body after contact by the user.
On the other hand, the generated volatile organic compounds (VOC) remain in the grass, and are emitted by the user on the site due to the influence of temperature, causing harm to the human body and the environment. In addition, due to the different uses of the recycled materials, it is inevitable that heavy metals will be introduced during the recovery, and will remain in the grass after being processed into grasses, causing potential poisoning damage to long-term contacts and causing water and soil environment. An irreversible hazard.
Note 2: Safety issues such as friction and burns
Because the structure of the artificial turf consists of rubber, concrete or asphalt, it can not basically play the role of water source, so it can not reduce the surface temperature, and its heat capacity is small. In the summer, in the closed stadium, the surface temperature may be greater than the air. temperature. If the user is subjected to intense friction with the user at this time, the skin at the contact site will be damaged lightly or severely. Moreover, the level of the process can also greatly affect the flame retardant properties of the grass.
Note 3: Static electricity and stagnation
Anti-static performance and stagnation are also the key points of artificial turf products competition, which is related to the scratch coefficient and final motion effect of the product. The evaluation of the advantages and disadvantages of artificial turf is the same as other products, mainly depends on whether the selection of raw materials such as straw, lining and the post-treatment process such as squeegee are mature and stable.
