How to Handle Cracks in Plastic Tracks

One reason is that during the installation of the plastic track, we use silane PU court materials. This material requires distribution, and during the distribution process, due to the lack of skill of the installation personnel, the mixing may be uneven, resulting in insufficient reaction between the two components.

Solution: The material allocation personnel must strictly adhere to the material proportion specified in the plan when laying plastic tracks and sports fields. They should increase the mixing time appropriately and only proceed after the materials and additives are properly mixed.

Reason two: Due to the undercoat layer not being fully dried, some unaware workers proceeded with the next step of the process, resulting in the two coatings not having compatible surface and internal elasticity.

Approach: Engineering supervisors strictly enforce construction standards, ensuring that the undercoating is completely dried and cured before proceeding to the next phase of work.

Reason three: Uneven coating thicknesses, with some coatings being too thin or too thick, can lead to cracking in the plastic track.

Approach: Standardly handle the root ground, while applying the undercoat, pay attention to the uniformity of the surface layer's thickness, and reinforce areas with thin coatings.

Reason four: Primarily, the surface material's evaporation must be too high in concentration of the thickener, which affects the bonding strength of the film formation and leads to cracking of the coating film.

Approach: It is advisable not to intensify the concentration of the thickener and additives during the distribution of surface materials.

Reason Five: The surface layer is too thick, and while the surface is dry and cured, there are still areas that have not dried properly.

The solution: When handling the surface layer of the abrasive ball, the thickness of each pass should not exceed 2mm, and the construction should be carried out in multiple passes.

As educational equipment continues to improve, people's living standards and skills advance accordingly. A landmark project, the construction of塑胶跑道, is bustling with activity. With the introduction of the塑胶跑道 technique to our country and its widespread application in schools, sports venues, residential communities, and other public places,塑胶场所 still offer numerous advantages over traditional sites.
