Why EPDM track or Spray coat track do not bubble ?

In the market, there are EPDM track, spray coat track,sandwich track, Full PU track, and prefabricated track .

It sepereted by permeable and non-permeable track,EPDM track and Spray coat track belong to permeable track,sandwich track, full pu track and prefabricated track belong to non-permeable track.

There are three reasons for rubber track bubbles:

1)The subbase problem; Regarding to Cement subbase, without waterproof layer When the cement foundation construct, or the cement was not maintained for 28 days after the completion of the cement, or the new cement foundation was maintained for 28 days but before the rubber track construction,it dont pickled （by OXALIC ACID） . These will cause blistering on the rubber tartan track.Regarding to AC (Asphalt) subbase, the asphalt was not compacted during construction. After the completion of the athletic track, the athletic track delamination and blistering, and the excavated rubber track was bonded with asphalt.

2) Raw materials;The raw materials of the track are mainly TDI, MDI, toner, plasticizer, etc., which we can commonly call rubber, toner and plasticizer. The amount of rubber is less, the toner and plasticizer are added, the resilience and rubber of the material are less, and the material is prone to problems, and it will also cause problems such as delamination and blistering.

3)Construction environment (Climate and Weather); Under the cloudy and rainy days to do application,the ground is not dry before the rubber track installed. The water vapor on the ground cannot come out. The PU material seals the ground, and the water vapor rises to produce bubbles.

Standard Basketball Court Size

1. The playing basketball court is 28 meters long and 15 meters wide. The ratio of long money: 28:15. The area of the competition area is 28*15=420 m2. 2. Line: The width is 0.05 meters (5 cm). Boundary: The court boundary is at least 2 meters away from spectators, billboards or any other obstacles. The boundary on the long side of the court is called the sideline, and the boundary on the short side is called the endline. 3. Free throw line, restricted area and penalty area: the area of the three-second zone = (3.6+6)*5.8/2=27.84m2 1. The free throw line should be parallel to the end line, and its outer edge is 5.80 meters away from the inner edge of the end line; this line is 3.60 meters long. Its midpoint must fall on the imaginary line connecting the midpoints of the two end lines. 2. The ground area formed by drawing two lines from both ends of the free throw line to 3 meters from the midpoint of the end line (both measured from the outer edge)...

Why does PVC floor warp?

Many consumers may experience warping when using PVC flooring. When the cardboard is warped, consumers can determine that this is a flooring quality problem, and exactly what causes the PVC flooring to warp. 1. because the poor quality, it will cause warpage problems. The structural stability of PVC floor is poor, and it is easy to shrink or expand at the alternating temperature of cold and heat, so it is easy to warp. The PVC floor production standard of the regular manufacturer, the floor quality is guaranteed, durable, and can reduce the chance of warping. 2. Architectural attachments can also lead to floor edges. PVC floor surfacing accessories are often used in latex, double-sided tape and pit knife glue. High-quality glue can make the floor and the ground stick together, and it is also very waterproof. If the glue is not good, it is easy to cause the floor to be weak and easy to bend. Of course, construction quality should not be ignored. Specialized construction personnel ...
