School playground plastic track

The construction process of laying the plastic runway is based on a three-step construction method. First, add an appropriate amount of rubber granules to the glue, and spread the bottom glue to a thickness of millimeters. After it solidifies, lay another glue liquid with a thickness of millimeters on top. Sprinkle red granules evenly by hand and recycle the excess. Glue
particles, and finally spray a layer of glue on them.

Laying of primer:
Before laying the primer, clean the foundation and prepare the tools for construction.
) Measure the location of the construction line according to the process requirements and place the construction line.
b) When laying, start from one side of the site and scrape the glue at one time according to the width of the site.
) Use a uniform speed when squeegeeing, and repair or smooth out exposed bottoms, depressions, and bulges in a timely manner.
) After the glue is formed, inspect the entire site to ensure the thickness of the surface glue.
Paving of surface glue:
) When scraping glue, try to shorten the interval between each barrel of glue to make the glue formation speed uniform.
b) Always observe the thickness of the rubber surface.
) Scrape the glue and sprinkle red particles before the glue solidifies. After it is completely cured, clean up the excess glue particles.
) Spray glue to ensure that the particles do not fall off.
Process line spray marking:
Accurately measure the position of the process line according to the current track and field facility standards, and then spray it with polyurethane paint.
