What effect does the smell of plastic on the plastic runway affect breathing?

Substandard plastic may cause dizziness, nosebleeds, and contains benzene, toluene, and free TDI

How long does the smell of the plastic runway take at least a year to slowly fade, the smell is caused by the volatilization of harmful residues of the plastic runway, which is harmful to the human body, you can usually sprinkle more water on the runway, which helps the volatilization of gas, before the gas is not volatilized, it is recommended to go to the gym, or other stadiums to fitness, running needs aerobic breathing, and other aerobic exercises, if you breathe the smell of plastic during this period is not good for the body, you can not achieve the effect of health and fitness.

Introduction to the plastic runway:

The plastic track, also known as the all-weather track and field track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. Domestic plastic runways are generally made of polyurethane materials, supplemented by pigments and additives. Polyurethane of qualified quality generally does not volatilize harmful substances.

Polyurethane is a chain-like molecule polymerized with two monomers, "polyether polyol" and "diisocyanate". If these two monomers are fully polymerized, then the polyurethane itself is not harmful. The key is that there will be more residues in the inferior polyurethane, and these two monomers that are not fully polymerized, and one of the most harmful monomers to the human body is these two monomers.

A year or so.

How long does the smell of the plastic runway take at least a year to gradually become lighter, the smell is caused by the evaporation of the harmful residual chemicals of the plastic runway, which is harmful to the body, and can usually sprinkle a few more drops of water on the sports field, which is conducive to the evaporation of vapor.

The plastic runway will be delivered for about 2 years, and the smell will slowly dissipate. Raw materials such as plastic polyurethane materials release some pungent odors under the hot and strong light, which is the same as the principle of tires.

Precautions for the use of plastic runways.

1. After the completion of the laying of the plastic runway, it can be used normally only after 7 or 10 days of maintenance.

2. When the plastic track has corresponding drainage facilities, it can be used all day long, and can only be used for sports training and competitions, and is not suitable for other purposes.

3. The plastic runway should avoid the pollution of harmful substances and violent mechanical impact and friction, and vehicles are not allowed to drive, pile heavy objects and sharp objects on the runway. Athletes must wear special sports shoes or sneakers, the length of the sneaker spikes should not exceed 9 mm, the length of the jumping shoes should not exceed 12 mm, and if the sneakers have long nails, they are not allowed to be used on the plastic track.

After about two years of use, the smell of the plastic runway will gradually dissipate. Plastic polyurethane is a material that releases some unpleasant odors in hot and strong light, which is the same as tires, after exposure to the sun, tires will also emit plastic smells. "The contact time is short, and under natural conditions, the unpleasant smell will be blown away by the wind, and it will not cause any harm to the human body normally.

A week or so.

Look at whether this plastic runway is indoor or outdoor.

The velocity of the plastic is related.

Look at what kind of plastic is used.

It is related to the quality and classification of plastics.

The plastic runway generally does not smell for such a long time, maybe there is a problem with the formula of the construction party of your school, and the normal construction will only smell during the construction and will be gone after a few days. This question still needs to ask whether your construction party has put any other materials in the process of producing materials to replace the original materials.

Plastic paving should be rubber, there are many kinds on the market, should be in the construction of the engineering staff to solve this problem, I have seen a lot of stadiums are also used, and there are some home decoration, you should choose the material should have a problem.

It should be gone for a year or so, because it is a little normal for plastic paving, as for the toxic just paving, it will be a little, and the impact will be smaller and smaller after a long time, but the overall impact is not large, and the plastic runway is very good except for this. Don't you know how your runway is usually sprinkled? It is much better to sprinkle more water on a regular basis, and it is also good for runway cleaning and durability.

It won't taste after a year, and that's probably a problem that the manufacturer knows, haha.

In recent years, plastic tracks are becoming more and more "close contact" with school students and athletes. However, the recent report that "plastic runways will release toxic gases" has made people jaw-dropping. As a result of these reports, students have been warned not to stay on plastic tracks for long periods of time, and in many places they have stopped paving ongoing tracks, and some schools are even considering demolishing existing expensive plastic tracks.

According to the reporter's understanding, at present, most of the primary and secondary schools in Beijing, Shanghai and Guangzhou have been paved with plastic runways, and some colleges and universities with good conditions even have more than two plastic playgrounds. In more cities, plastic runways have also become a necessary facility and grade evaluation standard for public sports venues. Whether it is toxic depends on the material of the runway, and if it is not good, it will cause the release of toxic chloride.

These toxins can easily enter the water, air and food chains, causing great damage to the environment. It has also been indirectly linked to cancer, hormonal imbalances, birth defects, diabetes, neurological damage and immunosuppressive consequences.

If it is a runway with quality problems, it is harmful to people at any time.

Silicone runway, harmless to the body.

It's poisonous, but it's just a little bit less odorless.

The raw materials of the plastic runway have been certified by the National Plastics Industry Association, which is non-toxic and harmless to the environment and the human body. And it has the characteristics of anti-ultraviolet light, anti-wear, anti-explosion, anti-aging, long life, easy maintenance, and low repair cost.

The main components of the plastic shelter runway are acrylic and high-quality resin, which are similar to convenient bags for food and meet the requirements of environmentally friendly surface materials. In November 2015, schools in Anhui, Henan, Jiangsu, Shanghai, Shenzhen and other places successively had "toxic runway" incidents.

Xinhua Viewpoint" reporter investigation found that some schools plastic spine lack of rubber runway raw materials suspected of "three no" products, toluene and xylene exceeded the standard by 139 times to enter the campus through the formal bidding process, campus engineering in the bidding, raw materials, construction, acceptance and other links There are loopholes.
