With the rapid development trend of economic development, people's living standards continue to improve, rubber runway has long been the standard configuration of many urban colleges and universities. Here let the plastic runway manufacturer take you to see the construction problems of the plastic runway, we will know whether it is difficult or not.

　　Rubber runway construction problems:

　　1. Plastic runway manufacturers say that the localized or large-scale bulging of the rubber runway occurs in a short period of time after completion, and even occurs when the rubber runway is basically detached. This situation is mostly related to the foundation negligence, such as the cement mortar ratio is not in place or the moisture-proof primer solution is not in place, resulting in the rise of surface moisture, topping up the rubber runway, resulting in bulging bags.

　　Solution.

　　To solve the basic situation, you need to pay attention to the basic moisture content and relative humidity of the air. The humidity of the construction environment is between 30% and 50%. Be able to do sample test before construction. In addition, if the paved playground has a bulge, you can use the laser to cut a part of the bulge, dry and then do the basic moisture-proof liquid, and then smoothed as required.

　　2. The fixing of the plastic runway is slow, even after the maintenance period is not dry, there is no compressive strength, and there is no high viscosity.

　　Plastic runway manufacturer said, here are three explanations:

　　(1) project construction, due to raw material deviation caused by the proportion of dislocation, such as composite rubber track, too many particles, so that the raw material is sticky, and even no compressive strength.

　　The metal catalyst is not added or the amount added is too small, resulting in a slow reaction or incomplete reaction of the raw materials. This is the profile of winter rubber track construction. In winter, due to the low temperature, the reaction speed of raw materials becomes slower, and the metal catalyst can accelerate the reaction speed of raw materials.

       The commonly used paint thinner is not enough, and there are other residues, such as aldehydes and water. This causes the molecular structure chain to be blocked when the plastic material is reflected, which prevents the production of polymer materials, or the ratio is out of proportion.

       Solution.

　　Before construction, check the scales and pounds for metrological verification to ensure that they meet the requirements; follow the strict requirements of the construction process and carry out the actual operation. Samples should be checked before construction to determine the quality of paint thinner, the quality or amount of metal catalyst to prevent unnecessary damage. Decide whether cleanup and resurfacing is required according to the specific situation.

　   (2) After the completion of the overall surface layer of the sports field ground layer, the latter process can not be solved sloppily, that is, painting lines on the sports field. Marking the rubber runway is not an easy task. If the construction team does not pay attention to locate the dotted line when drawing the line, it may jeopardize the overall practical effect of the rubber runway.

　　The solution.

　　is the procedural process of carving and detailed work. Plastic runway manufacturers say that in addition to ensuring testing instruments, mechanical equipment and special tools, the construction team should also have a strong sense of responsibility and serious work attitude. Measurement accuracy is one in ten thousand, and the steel tape measure used should take into account the metrological verification and changes in the number of feet. After the positioning dotted line is arranged, three people should be reviewed, and the line should be sprayed after the review meets the requirements. Each lane should have a spray box to ensure the symmetry and consistency of the playground slant line. During the whole spraying process, pay attention to clean the bottom box immediately to prevent the sprayed paint from dripping on the rubber runway surface to ensure that the rubber runway surface is beautiful, generous and neat.
