Whether it is a university, high school, primary school or kindergarten, the brightly colored plastic track has become the school's standard. Plastic runway flexibility, color bright, with a certain degree of anti-UV ability and anti-aging ability, can effectively improve athlete performance, reduce the frequency of student injuries. However, since 2014, the "poisonous runway" has become a hot spot in the society for several times. People have really talked about the color change of runways on the "hot runway" and "smell playground." Well, this runway, which originally brought unlimited fun to children, has become the culprit that endangers children's health.
Plastic runway is divided in breathable, mixed and precast, etc., of which breathable plastic is the school of choice, because it in the lowest. Breathable runway in the actual laying, usually in the asphalt or cement base layer of laying a layer of transparent polyurethane glue and "black particles" as the base, and then laying red and green polyurethane glue and EPDM particle mixture as the top layer , Of which "black particles" are mostly processed using waste tires.
In June this year, in Cangzhou 20 km away from the urban areas: the road on both sides of waste cable, waste tires and other waste rubber products piled up, and emits bursts of stench. In order to reap huge profits and reduce the cost of raw materials for runways, some undesirable enterprises have turned these rubber trash in black particles as the main raw material for plastic runways, thereby endangering the health of teachers and students and causing nosebleeds, allergies, dizziness and nausea symptom.
Visible unqualified rubber raw materials on the campus environment and the health damage caused by teachers and students is really great. Relevant state departments have stepped up supervision of the production process of plastic runways and hoped that the majority of campus plastic runway construction enterprises should not select inferior runway materials any more. Conscientious man and good faith work, choosing high-quality rubber raw materials and letting them lay plastic runways Become a real place for children to bring endless fun.
At present, in the production of rubber track, EPDM particles of various colors (most common is red and green) have excellent corrosion resistance and excellent chemical stability, resistance to ozone aging, resistance to oxygen aging, can be It is resistant to ultraviolet radiation and resistant to general chemical reactions. It can also maintain good elasticity in low temperature conditions. Its bright colors and low price make it an ideal material for laying indoor and outdoor playgrounds, soccer fields and basketball courts.
