耐磨地坪开裂问题解析
Analysis on cracking of wear resistant floor
耐磨地坪在使用过程中，受各种因素的影响，可能出现表面开裂的现象，影响地坪的整体性和强度。因此，针对耐磨地坪的开裂问题，需要进行全面而细致的分析，并采取相应的措施进行处理。
In the use of wear-resistant floor, affected by various factors, surface cracking may occur, which affects the integrity and strength of the floor. Therefore, in view of the cracking problem of wear-resistant floor, we need to conduct a comprehensive and detailed analysis, and take corresponding measures to deal with it.

1. Construction technology
要对耐磨地坪的开裂问题进行研究，首先必须明确其施工工艺，从流程方面对可能造成开裂的原因进行全面分析。耐磨地坪的施工工艺如下：
In order to study the cracking problem of wear-resistant floor, we must first clarify its construction technology, and comprehensively analyze the possible causes of cracking from the aspect of process. The construction technology of wear-resistant floor is as follows:
①在混凝土进入初凝阶段时，在其表面均匀铺撒骨料，在保证总量的情况下，分两次进行撒料，切实保证耐磨面层的厚度符合设计要求；
① When the concrete enters the initial setting stage, the aggregate is evenly spread on its surface. Under the condition of ensuring the total amount, the aggregate is spread twice to ensure that the thickness of the wear-resistant surface layer meets the design requirements;
②第一次铺撒骨料总量的70%左右，使用磨光圆盘对骨料进行压实搓毛；
② For the first time, about 70% of the aggregate is spread, and the aggregate is compacted and roughened with a polishing disc;
③第二次铺撒骨料总量的30%左右，使用抹光圆盘进行压实搓毛；
③ About 30% of the aggregate is spread in the second time, and the troweling disc is used for compaction and roughening;
④在混凝土完成初凝后，聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 使用压光机，对表面进行处理，确保其光滑平整；
④ After the initial setting of the concrete, the calender is used to treat the surface to ensure its smoothness;
⑤对耐磨表层的平整度进行细致检查，对低洼区进行及时补料，对凸出区进行适当削减，切实保证地坪的平整；
⑤ The smoothness of wear-resistant surface should be carefully checked, the low-lying areas should be timely supplemented, and the protruding areas should be appropriately reduced to ensure the smoothness of the floor;
