Talking about the "poison" of the "poison" in the plastic runway
The culprit may be a benzene additive
In that case, where is the problem? Where the smell comes from? The sports site synthetic material testing center of East China University of Science and Technology is one of the few related testing laboratories in China. The center staff, the general taste may be caused by the solvent inside the plastic runway, which is in the inside glue solvent. If some manufacturers do not operate too standard, the use of solvents is more, the time of volatilization must be longer.
It is used to lay the glue of plastic runway in Guizhou plastic runway factory.

And these "solvents", the national standard has no relevant regulations. If the runway uses inferior plastic particles, it will add benzene as diluent to smooth the surface. Benzene additive will cause skin itching and dizziness. In order to speed up the construction and make the runway quickly "dry" for use, some enterprises will also add lead salts to accelerate the solidification of runway, which is toxic to the environment and human body.
This shows that the toxic runway is mainly produced in the construction stage, and the plastic runway itself has no problem.
The price of the Plastic track company is also the reason for the manufacturer to cut down the work
Why is there such a problem? On the one hand, of course, it is related to some bad manufacturers, which should be dealt with severely, but on the other hand, there is a problem of price pressure. After investigating some of the manufacturers, the reporter also found that because of the cost problem, it became the usual practice of some manufacturers. Tang boss of Jiangsu once ran an elastic material production company for many years. He revealed that 20 years ago, the production of one square meter plastic racetrack could sell for more than 150 yuan. Now the labor cost is soaring, but the purchase price of plastic runway has dropped to 90 yuan to 120 yuan per square meter. Therefore, some bad manufacturers rely on cutting down to reduce the cost, the problem runway "arises at the historic moment". Tang also said that the quality to be guaranteed is more difficult, because the price is too low.
