    金刚砂耐磨地坪施工工艺上要注意哪些关键点

    金刚砂耐磨环氧地坪咱施工工艺上要求也是非常严格的,必须要按照规章制度来实施,那么要注意哪些问题呢?下边环氧地坪专家-环氧地坪给您讲下主要的注意事项。首先防止耐磨环氧地坪产生收缩裂缝主要是控制两个方面:一是撒布耐磨材料前控制好混凝土表面的干燥度,如混凝土表面有积水,须清理干净再进行撒布,否则积水部位容易出现干缩裂缝;二是及时切割伸缩缝,在水泥混凝土浇注2天后,即耐磨地坪完工1-2天后即进行切割,再晚将起不到作用。

    Diamond wear-resistant floor construction technology requirements are very strict, must be implemented in accordance with the rules and regulations, then what should be noted? The floor below the experts - floor to tell you the main points for attention. Firstly, to prevent shrinkage cracks on wear-resistant floor is mainly to control two aspects: one is to control the dryness of concrete surface before spreading wear-resistant materials, such as water on the surface of concrete, must be cleaned up and then spread, otherwise the dry shrinkage cracks are easy to occur in the water-accumulating area; the other is to cut expansion joints in time and pour 2. It will be cut after 1-2 days after completion of the wearable Floor. 其次环氧地坪施工的平整度主要靠水泥混凝土基层的平整度来控制,耐磨材料仅是表面很薄的一道致密层,所以控制混凝土初凝前表面的平整度是关键工序。建议严格控制水泥混凝土浇注 时的平整度,可采用一前一后两次刮杠找平。另外,在两条混凝土相邻的施工缝处,由于靠近施工缝模板处,在环氧地坪收光成型时抹光机不易打磨到,所以在施工缝处 容易引起高差。因此,在模板拆除后应进行施工缝清理工作。其方法是用切割机沿施工缝弹线切割掉50mm宽、深50mm左右的混凝土,并在二次浇注混凝土前 剔凿掉,以此确保二次浇筑的混凝土与已浇筑完成的混凝土接槎平直,注意弹线、切割应顺直。

    Secondly, the smoothness of floor construction is mainly controlled by the smoothness of cement concrete base, and the wear-resistant material is only a dense layer with a very thin surface, so controlling the smoothness of concrete surface before initial setting is the key process. It is suggested to strictly control the smoothness of cement concrete pouring, and it can be leveled one or two times after scraping. In addition, in the adjacent construction joints of two concrete, close to the construction joint formwork, the polishing machine is not easy to grind when the floor is formed, so it is easy to cause height difference at the construction joint. Therefore, the construction joints should be cleaned after the demolition of the formwork. The method is to cut the concrete about 50mm wide and 50mm deep along the elastic line of the construction joint with the cutting machine, and cut it out before the second pouring of concrete, so as to ensure that the second pouring of concrete and the poured concrete meet straight, pay attention to the elastic line, cutting should be straight.

    最后确保耐磨材料与水泥混凝土基层的良好粘结及地坪的色彩一致,主要是控制耐磨材料的撒布时机及每平米的撒布量,撒布应选择在混凝土初凝阶段,每平米的撒布量应通过两次撒布以达到撒布均匀,撒布量在6-8kg/m2。

    Finally, ensure that the abrasion-resistant materials and cement concrete base good cohesion and color of the floor consistent, mainly to control the timing of abrasion-resistant materials and the spread per square meter, the spread should be selected in the initial setting stage of concrete, the spread per square meter should be through two spreads to achieve uniform distribution, the spread of 6-8 kg/m2.
