However, the high polymer ice field plate has internal stress in the material forming process, and uneven load stress, uneven temperature stress and uneven distribution of assembly stress of the simulation plate caused by different illumination intensity, heat dissipation conditions, ambient temperature and the like of the installation site, and warpage is generated to influence the normal use of the simulation plate, and even large warpage at the joint and the buckle directly endangers the safety of athletes. Therefore, how to prevent the warpage of the simulated ice board during the process of designing, producing and installing the simulated ice board is one of the important points of work.
In addition, the existing simulated ice plates at home and abroad are mostly made of single low friction coefficient materials, so that the overall rigidity of the plate is ensured, the thickness is large, the production cost of the simulated ice plates is greatly increased, the quick popularization of the simulated ice plates is prevented, and more ginseng and ice rink movement are driven.
