[Abstract] it has a better effect on Athletes' speed and technology, which can improve the display of sports speed and reduce the fall injury rate. However, the UV resistance and aging resistance of the plastic runway need to meet the standard. Next, we will introduce the construction scheme of plastic runway renovation and plastic runway materials

plastic track is made of a variety of materials. It is an all-weather sports track, which is widely used in sports occasions. The surface of the plastic track is flat, and it also has high compressive strength, appropriate hardness, good elasticity, and stable physical properties. It is very suitable for professional sports. It has a better effect on the speed and technology of athletes, which can improve the display of sports speed and reduce the rate of falling injury. However, the UV resistance and aging resistance of the plastic runway need to meet the standard. Next, we will introduce the construction scheme of plastic runway renovation and plastic runway materials

1. Remove the garbage in the site, carry out basic inspection and make records according to the above methods, clean the ponding, dry it, and blow the dust in the site with a blower; Clean the batching and mixing site, and keep the area around the batching site clean

2. Use a steel wire brush to brush the mud and ash spots in the site

3. Use a hammer and drill rod to dispose of the dust that cannot be brushed off and the convex part, and then purge the whole site

4. Take a small amount of glue to accurately perform the national standard solution, and conduct a small-scale field test after being configured in proportion. After the experiment, proceed to the next process according to the experimental results

5. Seal the bottom of the foundation, level the ponding part with materials, and seal the places with unqualified compactness with glue

6. Adjust the scale of the paver as required, and then carry out the paving construction. The thickness of each part should meet the design requirements

7. After the base course is paved and hardened, drain water to find the ponding point, treat and level the ponding place according to the above process until there is no ponding in the primer. After the primer is completely hardened, Polish its surface with a grinder to meet the requirements of flatness, and then spray the surface for anti-skid

8. Mark various line positions in the site according to the drawings and design requirements

plastic runway material

1. Breathable plastic runway

is a double-layer polyurethane spraying runway system. The base layer is made of black environmental friendly rubber particles bonded by polyurethane resin, and the surface layer is made of colored EPDM rubber particles mixed with polyurethane and directly sprayed on the surface layer by SMG machinery

2. Composite plastic runway

the base layer is black environmental friendly rubber particles bonded by polyurethane resin, and the surface layer is colored EPDM rubber particles cast in polyurethane resin

3. Prefabricated plastic runway

is a type of coiled material runway that is prepared when it reaches a certain limit. Based on natural rubber and artificial rubber, mixed with mineral fillers, stabilizers and pigments, it is a double-layer synthetic rubber that is continuously calendered in the factory, and hardened at a high temperature of ℃, with mechanical embossing and consistent grain

4. Hybrid plastic runway

is a runway system composed of PU and black rubber particles in a certain proportion. When the materials are transported to the site, they are mixed in a certain proportion, mixed evenly with catalyst, paved and vulcanized at room temperature. This surface layer is a plastic surface material with national standards, which is mainly used in professional competition venues

plastic runways are used in sports venues. If plastic runways are used for a long time, in addition to the durable handle designed according to ergonomic principles to help users accurately dump and maintain them, it is also necessary to repair and renovate them. The above construction scheme can be used as a reference. In addition, plastic runway materials also need to be carefully selected. After all, the quality of runway materials determines the service life of runways and the lithium extraction from domestic salt lakes Major breakthroughs have been made in extracting lithium from lepidolite, and other information has been released and used
