Because silicon PU has excellent permeability and adhesion, it can be directly laid on cement concrete to reduce the cost of foundation construction or renovation. At the same time, because of the use of new technologies, new methods and new materials, its material cost is lower than that of PU*.
Silicon PU has been certified by the National Basketball Association and the Internet Association, and has obtained the ten-ring certification (Ten-ring I-type mark) of the Ministry of Environmental Protection in terms of environmental protection certification. This is the standard for distinguishing real and fake silicon PU.
The silicon PU court is tough, dense, and not easily scratched by other hard objects on the sole. The silicon PU court can cover the concrete expansion joints and keep the court as clean as new for a long time. It can be seen that the silicon PU stadium is indeed a better choice for the construction of sports venues!
Introduction to the types of basketball court ground materials:
1. Soil court: It is very rare at present, but 20 years ago, in many places with poor conditions in our country, there were often such soil court basketball courts. Even at present, in some impoverished areas of our country, there are still basketball courts with soil surfaces. The advantage of the soil basketball court is that the construction is simple, as long as there is a flat ground. Its big disadvantage is that the ground is easily affected by the weather, there is no way to play basketball after rain, and there is also a lot of dust in windy weather, which causes the movement to not be carried out normally.
2. Concrete courts: Concrete basketball courts are still common. In schools in rural areas of many counties and cities, basketball courts are built with cement. The advantage of the cement floor basketball court is that its ground is more flat than the soil ground, it is not easy to be damaged, it is less affected by the weather, and it is relatively safe. But its disadvantage is that the ground is hard and the elasticity is not good, and it is easy for athletes to fall and suffer serious abrasions or impact injuries during exercise.
3. Asphalt field: At present, many school basketball courts in small and medium-sized cities use asphalt ground, which looks clean and tidy, and the ground has a certain elasticity, so athletes will not be injured when they fall. But this kind of ground cannot be used when the temperature is high in summer, because the asphalt will be softened by the hot sun, and a lot of asphalt will stick to basketball when playing basketball, and people will also stick some asphalt when they step on it, so there are many outdoor basketball courts no longer Make a basketball court out of asphalt.
4. Wooden floors: At present, some higher-grade places, such as clubs and better universities, use wooden floors. It is more convenient to clean the field, and the elasticity is the best, and the athletes are not easy to be injured during the competition. Of course, this kind of wooden floor is mostly used for indoor basketball courts, and the wooden floor of outdoor basketball courts is rare. The price of wooden floors is too expensive, so due to economic constraints, many venues do not use such floors.
5. Plastic floor: Plastic basketball courts have become popular in recent years and are widely loved by schools and other units. The construction is convenient and pollution-free. It is easy to maintain in daily use, can be used indoors and outdoors, and is not affected by the weather environment. Due to the good elasticity of plastic, athletes will not be injured because the floor is too hard during the game.
With the attempts of some customers, small areas and small venues are laid and used for comparison; then to the reputation of athletes’ own sports experience, silicon pu materials finally live up to the high expectations, from being questioned by the market to being gradually recognized by the market, and then to the market The comprehensive promotion and popularization of silicon pu is inseparable from the advantages of silicon pu itself.
Silicon PU can also be directly constructed on the cement floor. The excellent water-based surface layer of silicon PU can ensure the long-term stability and stability of the surface structure, and the high-quality performance meets the needs of long-term high frequency of use. The silicon PU surface layer is firm and dense, and it is not easy to be scratched by the sole. After a simple rinse, the court can be kept as bright as new for a long time.
The silicon PU developed by using the polymer interpenetrating network technology has particularly excellent elongation, stain resistance, aging resistance, anti-aging and scratch resistance due to its extremely tight structural connection. According to the principles of sports mechanics, the ingenious three-layer structure design makes the elasticity of the sports field ground to achieve the most reasonable arrangement, which is conducive to the protection of the athletes’ joints and the favorable performance of the athletes.
Silicon Pu court is an indispensable environmental protection floor for sports venues. Its service life can last for more than 8 years. However, due to improper climate or artificial use, the surface of some silicon Pu courts will appear discoloration, chalking, delamination, cracking, bulging, etc. phenomenon, which directly affects the use of the site. In these cases, how to properly repair the damaged silicon Pu court is particularly important.
Generally speaking, the construction process of silicon Pu court includes:
Preservation of the elastic layer and treatment of the base surface: Knock off and scrape all the falling surface layer with a sander. Then clean the base surface.
Interface agent: After the foundation surface is treated, a layer of interface agent is scraped on it to form a closed layer.
Elastic layer: Use a toothed scraper to coat the silicon Pu elastic material on the base surface, each layer is 2mm thick, and the interval between each layer is dry and solid until the coating reaches the required thickness.
Topcoat: The silicon Pu material is mixed in proportion and rolled with a roller for 2 layers. It has strong weather resistance and light radiation resistance, making the surface of the venue bright and beautiful. Use silicon PU line paint to draw lines according to the standard field.
After long-term use, the surface of the silicon Pu court will appear chalking, falling off, and foaming, so there is no need to panic. Generally, a 3.0mm silicon Pu surface layer can be made on it before use to cover the powdered and peeled parts. These are only covered over the original foundation, if the site is severely damaged, refurbishment of the entire site may be considered.
Construction steps of silicon PU court floor
1. Base surface treatment
The quality of the base surface largely determines the quality of the silicon PU on-site engineering. The site should be cleaned before construction. The new concrete site needs more than 28 days of curing and curing before laying materials for construction.
2. Lay the elastic layer
Before constructing the elastic layer, the foundation treatment should be carefully checked and confirmed, and the construction of the elastic layer should be carried out only after the confirmation is correct. Add solvent to adjust the consistency of the silicone PU court material, and lay it on the base surface with a flat scraper or a tooth scraper until the desired thickness is achieved. Construction under the scorching sun should be avoided. After the elastic layer is left to dry, use the water accumulation method to test the ground flatness, and level the water before placing the reinforcement layer.
3. Lay the reinforcement layer
After adding the solvent to adjust the consistency of the silicone PU court material, the elastic surface is laid in several layers with a rubber scraper, and the surface is required to be smooth and flat after laying. If debris or unevenness was mixed in during application, surface application should only be done after trimming and smoothing.
4. Lay the top surface
Stir components A and B according to the proportion, add a small amount of water to adjust the construction consistency, and use a rubber spatula to scrape the surface of the reinforcement layer 2 to 3 times. If the surface needs to be rough, ≤30% surface sand can be added. Ingredient A and sand should be mixed well, then added to Group B, stirred well, and scraped. (Reference practices for various court surfaces: table tennis, basketball courts: add 30% sand for the second track, add 15% sand for the second track, and no sand for the third track; add 30% sand and divide into 2 to 3 scratches; Badminton and volleyball courts: 2 to 3 scratches without adding sand). Sufficient amount of surface building materials is required, otherwise it will directly affect the use effect and service life. Construction under the hot sun and excessive surface temperature should be avoided to ensure the surface effect.
5. Scribe
Measure and locate according to the standard size, mark the location of the boundary line, stick it on the court along both sides of the boundary line and use the marking paint between the masking papers, apply the marking paint between the masking papers and let the surface dry Then tear off the textured paper.
6. Cleaning and maintenance
After the floor is completed, clean up the site and start maintenance, and the maintenance period is not less than 20 days
