Stadium PU floor construction basic requirements

PU (Polyurethane) is an emerging organic polymer material that has been widely used in many fields due to its excellent performance. PU plastic ground sports grounds are available for all-weather use, such as the PU tennis court floor with excellent environmental performance, superior durability and compatibility. Long service life, easy construction and maintenance, it is the advanced sport ground that sports field has taken priority in recent years. In the process of construction of PU plastic flooring, it is necessary to strictly comply with the relevant national standards and standards, and strictly control the quality of the ingredients, ground finishing, primer coating, paving, trimming and other processes, so that they can have a qualified building product. PU plastic flooring is a successful practice and provides good sports facilities for employees to carry out ball activities.

PU球场施工

1, plastic base pavement construction method

Ground Finishing: The dust on the surface of the basement is cleaned, and the dripped cement mortar and oil are wiped clean with solvent. Ground bumps must be removed with a sand mill or a spatula. The pit or crack is repaired with a substrate. The ground should be dry. If the ground is wet, use a fire extinguisher to dry it. Check the flatness of the ground and meet the specifications.

Primer: brush or brush cross-horizontal cross-coating, evenly coated, primer coating to avoid the formation of small bubbles. Paving: Design thickness 7. The paving machine is used to spread the base rubber buffer layer and the material is a tread rubber pad. The adhesive is a one-component colorless MDI polyester adhesive. The adhesive and the black EPDM particles are stirred well in a certain proportion and sent to the paver for on-site paving. In the paving process, manual fill-in methods are used for the missing materials. After the paving finishes curing, the paving layer is inspected and the protruding part of the black EPDM grain is trimmed with a trimming knife.

2, excellent environmental performance

Advanced technology, to overcome the difficulty of MDI single-component polyester construction, the use of reclaimed rubber particles and anti-aging and super anti-mildew factors extracted from plants, odorless, non-toxic, non-irritating odor, is a green product.

3, super durable performance

Physical and chemical stability, the impact of the elastic polyurethane floor performance guarantees use under normal conditions and is maintenance-free. Its color will not fade due to UV, ozone, wind and rain, and the pollution of sulfurous acid and gas, and it will remain bright for a long time. The surface layer particles will be hard-wearing and suitable for high-density, ultra-strength training and competition.

4. People-oriented sports performance

With moderate elasticity and friction coefficient, it can not only absorb the impact force of the footsteps, reduce sports injuries, but also reduce physical exertion, so that the human body can obtain continuous forward momentum, improve competition results, soft colors, beautiful appearance, and can have a changing environment Features.

5, plastic surface layer construction method

After the construction of the grass-roots level, it is required to be completely dry before the construction of the plastic surface layer, generally the next day construction. Before paving plastics, clean the asphalt surface first and then plastic pavement. The person responsible for the material is responsible for the material registration and supervising the mixing of the rubber material. Keep track of the work at any time and strictly ensure the thickness and flatness of the surface layer. According to the provisions of the national standard GB/T14833-93 for inspection. If there is a dent or uneven surface, fill it with a substrate or face material.
