In recent years, the laying of plastic runways has shown a linear upward trend. Under the slogan of "national fitness", many unscrupulous businessmen blindly build sports venues, only pay attention to economic benefits, ignore the quality and safety of runway materials, and cut corners during the construction process, resulting in the substandard quality standards of plastic venues and persistent odor of plastic venues. In fact, the plastic yard will produce some choking smells during the laying process. Before the plastic runway is completely solidified, it is normal to have a choking smell in the air, mainly because of the volatilization of glue. Usually there will be no problem for a few days. This process usually takes three to five days. Of course, some construction units may spray some things in order to speed up the curing of glue, so that the time for emitting odor will be shorter. However, in order to reduce the cost, some construction units used some inferior glue. The quality problem of the products of material suppliers has also become the reason why the plastic site has a taste.

In view of whether the unpleasant smell of plastic track is harmful to human body, see the expert's opinion:

There will be less and less harmful gases.

Professor Chen Fan, School of Chemistry and Materials Engineering, Wenzhou University: At present, the main components of plastic runways are basically industrial polyurethane, which will release harmful gases under high temperature and strong light, especially those who are sensitive to respiratory tract. However, the volatility of these harmful substances is very small, and the plastic runway is by the river, so the public contact time is relatively short. In addition, there is a certain process of volatilization, degradation and aging under natural conditions, and these gases will be less and less. Generally speaking, they are not harmful to people.

It may be related to the convenience of construction drawings.

Chen, director of the testing laboratory of synthetic pavement in venues of China Athletics Association and a professor at the School of Materials Science and Engineering, East China University of Science and Technology, said: Theoretically, if the plastic track emits odor, it may be related to the insufficient chemical reaction during the processing of plastic track materials, or the toluene substances added in the laying of plastic track to facilitate construction and enhance adhesion.

The products of individual enterprises have high content of heavy metals.

Ma, director of the testing institute of China Institute of Building Materials Science: According to the testing reports of plastic runways made by the institute in recent years, the main environmental protection projects that people are most concerned about, such as formaldehyde and benzene, have not been detected, but the products of individual enterprises once had high values of heavy metals such as lead.

In fact, if you choose high-quality material suppliers to cooperate and hire professional construction personnel, you don't need to worry about the quality of the runway at all. People will be happy when they exercise on the environmentally friendly plastic track. For a long time, Heilongjiang Vanke Construction Engineering Co., Ltd. has been specializing in the construction of plastic runways. The products are green, tasteless, quality pass, national standards, reasonable price, worry-free after sale, professional team and rich experience. Vanke's brand and service concept are deeply rooted in the hearts of consumers. Many cases of plastic runways are classic. It is the eternal pursuit of Heilongjiang Vanke Company to be the most assured and environmentally friendly playground material.
