Guangdong Fengneng Environmental Protection-product classification of sports venues;
Our company's sports venues are divided into the following categories: elastic acrylic sports venues, hard acrylic sports venues and silicon PU sports venues.
However, different types of stadiums and gymnasiums should have different construction schemes. So what are the construction techniques and methods of Guangdong Sipu Stadium today?
Guangdong Fengneng Environmental Protection-the advantage of Sipu Stadium;
Silicon PU court material (SPU) is a new generation of court paving material developed on the basis of PU court material. This material is composed of polyurethane (PU) and silicon-containing materials. The produced materials are used on the surface of the court, which fundamentally and effectively solves the shortcomings of PU court materials in professional performance, environmental protection construction, service life and daily maintenance, and is revolutionary and innovative.
The well-designed "hard outside and soft inside" three-layer composite structure silicon PU court material is a new type of plastic court covered by silicon modified polyurethane material (bottom coating, elastic layer, strengthening layer and surface layer), which has the structural characteristics of hard top and elastic bottom, forms a scientific sports safety guarantee system, effectively protects sports injuries and meets the requirements of shock absorption and rebound, and belongs to a healthy professional elastic synthetic court ground system.
Guangdong Fengneng Environmental Protection Technology Co., Ltd. is a national enterprise in the field of environmental protection rubber integrating R&D, production, sales and construction. Its products are cheap, cost-effective, deeply loved by consumers and exported to many countries on five continents. Its silicon PU sports ground products have the following advantages:
What are the advantages of Sipu Stadium?
1, surface layer: water-based and environmentally friendly, in line with the theme of healthy sports. Adding silica gel to modify, it is more wear-resistant, easy to color and diverse in color.
2. Waterproof layer: The unique silicone modified polyurethane waterproof material has stronger permeability to cement pores and better adhesion to polyurethane elastic layer.
3. Elastic layer: scientifically match the coefficient of thermal expansion and cold contraction of cement to reduce site cracking caused by thermal expansion and cold contraction.
4. Economy: Silicon PU has excellent permeability and adhesion, which is suitable for laying new and old cement or asphalt base, reducing the cost of infrastructure construction or renovation, and the material cost is lower than that of PU, and the comprehensive use cost is high.
5. Durability: The adhesive force of silicone modified waterborne polyurethane new technology adhesive has reached the international A-class standard, the anti-slip value is stable and adjustable, and the tensile strength and aging resistance are excellent.
6, aesthetics: polymer coloring technology, rich and lasting colors, suitable for stadium and TV broadcast lighting, more delicate and uniform.
Construction technology and method steps of Guangdong Fengneng Environmental Protection-Sipu Stadium;
Construction technology of Sipu Stadium;
1, elastic layer:
Before the construction of elastic layer, the foundation treatment should be carefully checked and confirmed before the construction of elastic layer can be carried out. The elastic layer is a one-component material, so it is only necessary to adjust the proper construction consistency with thinner and apply it to the base surface with a toothed scraper. The thickness of each coating shall not exceed 65438 0.5mm, and the time interval of each coating shall be subject to the previous drying (generally about 65438 00 hours, depending on the weather conditions on site) until the coating reaches the required thickness. Pay attention to the leveling effect when scraping. If you can't scrape the scratch, you need to add more thinner to ensure the surface is flat. If the air temperature is low (< 10℃, and the relative humidity is low < 60% =), it is necessary to add (0.5- 1%) water, stir it evenly and smear it to accelerate the curing of the material and reduce the interval time. The specific amount of water added depends on the weather on site, and construction under sudden exposure should be avoided. After the elastic layer is dried and consolidated, the surface flatness is detected by water accumulation method, and the water accumulation place is repaired and leveled. If there are granular sundries or accumulations on the surface, it should be leveled with a mill or other tools before the construction of the stable layer. (3.0 mm thick)
2, strengthening layer:
The reinforcing layer is a one-component material, which can be used directly after opening and can be directly rolled or sprayed on the elastic layer. If it is under the scorching sun or the base temperature is high (> 45℃), 30-50% thinner (dimethyl carbonate or butyl acetate) can be added in the roller coating construction, and the surface after roller coating must be smooth and flat. In the process of construction, if impurities are mixed in or uneven parts are scraped out, the surface construction can only be carried out after finishing and smoothing. (0.25mm thick)
3. Surface layer:?
The topcoat is a two-component water-based material, and the two components must be fully and evenly stirred according to the specified ratio (curing agent: color paint = 1: 15 (weight ratio)). (Inaccurate proportion will affect the curing effect of topcoat, and directly affect the performance of topcoat. ) Adjust the construction consistency, generally add 10-20% quartz sand (calculated by the weight of top coat), and only add special sand to the rough surface for construction. The lowest temperature below 5℃ is not suitable for construction. After construction, keep 10 hour without water immersion. (0.25mm thick)
Construction methods and steps of Sipu Stadium;
1, ground temperature joint and irregular joint treatment-acrylic acid intermediate coating, water filling and scraping elastic layer.
5. Scrape off joint sealant -6. Fill the dead water -7. Scrape the solid layer -8. Scrape the surface layer of color separation sand.
9. Scrape the pure surface layer-10, and cross it-1 1 to finish.
Note: 1, the temperature shall not be higher than 35C in summer, and construction shall not be carried out when the ground temperature is lower than 10C in winter. If there is spraying equipment during construction, the surface effect of color separation layer/pure surface layer will be better
