| （1）所用胶粘剂达不到质量、性能要求，采用机械固定时锚固件的埋设深度和锚固数量不符合设计规范；粘结胶浆配比不准确，选用的水泥不符合技术要求；粘结面积过小，未达到相应产品设计规定。 (1) The adhesive used can not meet the quality and performance requirements, the depth of anchorage and the number of anchorage parts do not conform to the design specifications when mechanical fixation is used; the proportion of cement paste is not accurate, the selected cement does not meet the technical requirements; the bonding area is too small to meet the corresponding product design requirements. （2）基层表面的平整度超出基层允许偏差范围；其表面含有妨碍粘贴的物质，未进行界面处理。 (2) The smoothness of the surface of the base exceeds the allowable deviation range of the base; the surface of the base contains substances that interfere with adhesion, without interface treatment. （3）采用的挤塑板密度不足，抗拉强度过低，满足不了保温系统自重及面层荷载对其强度的承载要求，导致挤塑板被拉损破坏。 (3) The density of the extruded board is insufficient and the tensile strength is too low, which can not meet the requirements of the insulation system weight and surface load on its strength, resulting in the tensile damage of the extruded board. |
