Plastic runway degumming phenomenon is a frequent occurrence, why do you say so? Because many manufacturers of materials and construction team of incorrect construction methods can lead to problems, specifically by what causes, and how to fix it? The following TECS sports to introduce you in detail.

　　First, the edge of the plastic runway degumming is what causes?

　　1, surface rubber cracking

　　Generally in the plastic runway delivery after use, after exposure to sunlight or precipitation infiltration will appear after this situation, the first pu glue in the construction of plastic runway, raw materials in the middle of the adhesive must be glued together, then this kind of adhesive is often said that the pu glue, if the pu glue is not off will cause the actual effect of the adhesion of the poor, then deglossing is bound to produce the problem. Second is the particulate matter raw materials, the most common raw materials is eppdm particulate matter raw materials, generally not pass the eppdm particulate matter through the sunlight will appear molting, may lead to plastic runway deglossing problem.

　　2, basic cracking

　　The basic cracking cause is the foundation project construction is not pass, resulting in the place of disproportionate foundation settlement, which leads to basic cracking. The glue of the poor resistance to base cracking, the structural layer and then by the basic cracking amplitude ripped leading to structural layer cracking.

　　Second, how to repair the plastic runway edge degumming?

　　1, remove

　　In the damaged position drawing line marking, with a wallpaper knife along the outer edge of the drawing line evenly removed. Dig to a similar ring-shaped pit, along the outer edge of the removal of a 5mm wide steep slope, followed by cleaning and tidying the sand at the bottom, drying the foundation base.

　　2、Make up

　　For the repair position in accordance with the plastic materials prepared in advance to carry out plastic ductile layer repair, near the border to ensure that the delicate and even, thin and thick moderate.

　　3、Spray paint structure layer

　　This procedure is a very critical plastic runway processing technology, divided into 2 times engineering construction, that is, must be interspersed with two times of spray paint. The first and second time the orientation of no actual very stipulated, but must be differently skewed spray paint, and no significant connection head after spray paint.
