The impact of different climatic conditions on silicon pu court is reflected in many aspects. These impacts involve not only the stability of material performance, but also the experience and service life of the court. They need to be analyzed in combination with specific climatic characteristics. In a hot and hot climate, the main problems faced by silicon pu court are thermal expansion and contraction and accelerated aging of materials. Long-term exposure to strong sunlight will cause the surface temperature of the court to rise sharply, causing the silicon PU layer to soften, the elasticity to decrease, and the foot feel to become sticky, affecting the flexibility during exercise. At the same time, high temperature will accelerate the volatilization of chemicals in the material, causing the surface layer to fade, harden, and even crack, especially in open-air courts without sunshade facilities, this aging process will be more obvious. In addition, if the frequency of use of the court is high in hot weather, repeated friction between people and equipment will further aggravate the wear of the surface layer and shorten the effective use cycle of the court.
In low and cold climate conditions, the material properties of silicon pu court will change significantly. Silicon PU itself has a certain degree of cold resistance, but when the temperature is lower than its adaptability range, the material will gradually become hard and brittle, the elasticity will be greatly reduced, and the original buffering performance will be lost. At this time, when exercising on the court, the impact force felt by the feet increases, which is easy to increase the burden on the joints and may even cause sports injuries. If the low temperature environment is accompanied by rain and snow, the surface of the court will freeze or accumulate water. The freezing and thawing of the ice layer will cause the silicon PU layer to peel off from the base ground, forming hollowing or blistering. Especially in areas where the temperature rises and falls repeatedly, the snow melts during the day and penetrates into the gaps in the material, and freezes and expands at low temperatures at night. This freeze-thaw cycle will cause structural damage to the court structure, and in severe cases, large-scale renovation may be required.
The impact of rainy and humid climate on silicon pu court is mainly reflected in drainage and material corrosion. If frequent rainfall cannot be discharged in time, it will cause long-term water accumulation on the court. The accumulated water will penetrate between the silicon PU layer and the foundation, weakening the bonding force between the two and causing the surface layer to bulge and fall off. At the same time, the acidic substances carried in the rain or the pollutants in the air dissolved in the accumulated water will slowly corrode the silicon PU material, destroy its chemical structure, and cause the surface layer to change color, lose gloss, and even powder. In addition, a humid environment is prone to the growth of mold and algae. These microorganisms will adhere to the surface of the court, which not only affects the appearance of the venue, but also makes the ground slippery and increases the risk of slipping, especially in shaded areas or areas with poor drainage. The mold reproduces faster and the difficulty of cleaning and maintenance increases accordingly.
Under the climate conditions of high-altitude strong ultraviolet radiation, the biggest challenge facing silicon pu court is the degradation of materials by ultraviolet rays. The air in high-altitude areas is thin, and the intensity of ultraviolet rays is much higher than that in low-altitude areas. Long-term ultraviolet radiation will destroy the polymer chains in the silicon PU material, causing the surface layer to age significantly faster. Specifically, the color fades quickly, and the originally bright court surface gradually becomes dull. At the same time, the elasticity and toughness of the material decrease, becoming hard, brittle and brittle, and cracked lines appear. In addition, strong ultraviolet rays will also accelerate the aging of court auxiliary materials such as glue and seam tape, causing cracking and degumming at the joints, affecting the overall flatness and safety of the court. If not handled in time, the damaged area will gradually expand, affecting the normal use of the court.
The climate in coastal areas is characterized by high salt fog and high humidity, which is highly corrosive to silicon pu courts. The salt fog particles carried in the sea breeze contain a large amount of chloride ions, which will corrode the silicon PU material through physical adsorption and chemical action, especially metal parts such as water retaining strips and embedded parts at the edge of the court, which are prone to rust, thus affecting the structural stability of the court. At the same time, the high humidity environment will keep the silicon PU layer in a humid state for a long time, reduce the bonding strength of the material, and cause the surface layer to separate from the base layer. In addition, the combined action of salt fog and humidity may also cause electrochemical corrosion of the material and accelerate the aging of the court, making the silicon pu courts in coastal areas require more frequent maintenance and care to cope with the damage caused by the special climate.
In windy and sandy climate conditions, the surface layer of the silicon pu court will be continuously abraded. In windy and sandy weather, fine sand particles will constantly rub the surface of the court under the action of wind, gradually wearing away the protective layer of the silicon PU surface layer like sandpaper, exposing the rough aggregate, and affecting the flatness and friction of the venue. Long-term wind and sand erosion will lead to a decrease in the elasticity of the court, an unstable rebound trajectory of the ball, and affect the sports experience. In addition, sand accumulation in the gaps or drainage holes of the court will block the drainage system, aggravate the problem of water accumulation, and further damage the structure of the court. Frequent wind and sand will also increase the workload of cleaning and maintenance, and the venue needs to be cleaned regularly, otherwise the excessive accumulation of sand will accelerate material wear and shorten the service life of the court.
Comprehensively considering the influence of different climatic conditions, it can be found that the performance and life of silicon pu court are closely related to the environment in which it is located. In order to cope with these climatic challenges, it is necessary to consider the regional climate characteristics during the design and construction of the court, and select suitable material formulas and construction processes, such as using anti-aging additives in high temperature areas, using cold-resistant silicon PU materials in cold areas, and optimizing drainage systems in rainy areas. At the same time, in daily use, targeted maintenance plans should be formulated according to climatic conditions, such as avoiding use during the hot season, timely watering and cooling; doing a good job of antifreeze protection in winter in cold areas; regular anti-corrosion treatment in coastal areas, etc. Through scientific response measures, the adverse effects of climate factors on silicon pu court can be minimized, its service life can be extended, and its safety can be guaranteed.
