During the construction of plastic running tracks in stadiums, sometimes plastic bubbles appear. This is mainly due to the use of a formula containing excessive water content in the product during construction.
During the construction of plastic running tracks on the field, sometimes plastic bubbles appear. This is due to the use of a formula with excessive water content in the materials during construction, which is the main cause of bubbles. Details are explained below.
Water mainly comes from:
1. Air humidity (moisture) during construction;
2. Water content of the material itself;
3. Water content of the base;
4. Diluent or filler (rubber powder, colloidal particles, or sand).
1. Causes of air humidity during construction
During construction, engineers are forced to work in a rush, and morning dew may not be dry. High air humidity during the rainy season in the south, and poor control of construction time. As a result, the water content of the construction conditions at that time was very high, which usually did not cause problems on the construction day. The next day, the entire surface would bubble under the sun. The size of the bubbles depends on the amount of water vapor. The more water vapor, the larger the bubbles.
2. High water content of the material itself
When purchasing raw materials, only national standard products from state-owned enterprises are purchased to effectively control excessive water content. The first level effectively controls excessive water content, improves the production process, vacuums and dehydrates the material, and performs a second-level echo purification process. When the material arrives at the factory, it is water-free and environmentally friendly.
During material transportation and on-site storage, before construction, the packaging barrels must be carefully checked or small sample experiments conducted on-site. Only after successful experiments can construction be planned. Excessive water content in the material from the factory constitutes the cause of bubbling. The size of the bubbles depends on the amount of water vapor. The more water vapor, the larger the bubbles. Some packaging barrels are damaged by bubbles. The size of the bubbles depends on the amount of water vapor. The more water vapor, the larger the bubbles.
3. High water content of the base
The base was not protected according to specifications, or even well-maintained bases and old bases become dry on the surface due to rain, landscaping, and watering, while the inner layer still has high water content, causing bubbling. Areas with accumulated water have higher water content and more serious bubbling. Generally, there are no problems on the construction day, but the next day, bubbles will appear under the sun. The size of the bubbles depends on the amount of water vapor. The more water vapor, the larger the bubbles.
4. High water content of construction filler
During construction, a high water content of diluents involved in leveling can lead to bubbling. Fillers (rubber powder, colloidal particles, or sand) with high water content (damp or moldy fillers) can also cause bubbling. The size of the bubbles depends on the amount of water vapor. The more water vapor, the larger the bubbles.
