First, the reason for choosing:
Generally speaking, primary and secondary schools in the 9-year compulsory education stage, including public kindergartens, will use the new national standard GB 36246-20 18, which is a poisonous runway phenomenon that frequently appeared in China before 20 18.
This standard is mainly to strengthen the chemical properties, so the plastic track paved with this standard is very environmentally friendly, and students will not faint with nosebleeds as before. When these situations occur, even indoor ones are fine.
In addition, the physical properties are strengthened, that is, the impact inside absorbs vertical deformation, which mainly improves the protection of students during sports.
Second, the standard runway:
According to the actual needs of schools at present, most primary and secondary schools mainly use 200-meter plastic runways. According to market research, primary and secondary schools generally tend to lay breathable plastic runways. The breathable plastic track has low requirements on foundation and excellent adaptability, which is very suitable for primary and secondary schools.
For example, high schools generally use a 300-meter-long standard plastic track. Some high schools will choose to build a 400-meter plastic track when the budget is sufficient.
The plastic track in the school playground has the following advantages:
1, anti-skid safety:
The surface of the plastic track has a certain friction force, which is not easy to slip and can ensure the safety of runners; In addition, the plastic track can effectively reduce the friction damage during running and protect the health of runners.
2, comfortable and durable:
The material of the plastic track is soft, which can effectively slow down the impact of running and reduce the harm to the body. At the same time, the plastic track has good durability and can withstand years of use and changes in various climatic conditions.
3, beautiful and environmentally friendly:
The plastic track of the school playground is not only beautiful in appearance, but also can be customized according to different needs to meet the needs of campus beautification. In addition, the plastic material itself has good environmental protection and will not pollute the environment, which conforms to the modern concept of energy saving and environmental protection.
