济南岩棉板裂缝有几个原因：

There are several reasons for the cracks in Jinan rock wool board:

1.保护层和隔热层之间的粘合强度低或存在空的岩棉板。

1. The bonding strength between the protective layer and the thermal insulation layer is low or there is empty rock wool board.

2.由于门窗入口和出口处的应力集中，保护层和饰面层有缺陷。

2. Due to the concentration of stress at the entrance and exit of doors and windows, the protective layer and finishing layer are defective.

3.岩棉板的铺设与温度应力变形之间存在差距。

3. There is a gap between the laying of rock wool board and the temperature stress deformation.

济南岩棉板防裂措施：

Anti-cracking measures for Jinan rock wool board:

1，采用微细紧固抗裂砂浆或聚合物砂浆，粘接强度高，收缩变形小，无弹性。由于岩棉板具有柔软的质地，因此防裂砂浆的厚度优选为25-30。

1. Adopt micro-tightening anti-crack mortar or polymer mortar, with high bonding strength, small shrinkage deformation and inelasticity. Because rock wool board has soft texture, the thickness of anti-crack mortar is preferably 25-30.

2，采用钢丝网或钢丝网夹层岩棉板加固层，一方面将钢网或加强结构层与保温层和爱层相邻，另一方面或分散的爱的收缩应力层和面层层压力集中，从而达到减少和避免间隙呈现的目标。在壁易于形成间隙的部分中，须采用加强网的步骤的一部分。在建筑物的立面上，门和窗口的存在自然地将立面分成水平和垂直的小块，这会导致应力集中，特别是在窗户中。拐角更加明显，在这些应力集中容易产生裂缝，并且不断扩大和扩大。在过去，一般的做法是使用钢丝网在这些位置密封岩棉板的边缘，并且应该在窗户角落周围的岩棉板上添加一层钢网以增加抵抗压力集中的能力。

2. The steel mesh or steel mesh sandwich rock wool board is used to reinforce the layer. On the one hand, the steel mesh or reinforced structural layer is adjacent to the thermal insulation layer and the surface layer, and on the other hand, the dispersed shrinkage stress layer and the surface layer are concentrated, so as to achieve the goal of reducing and avoiding the gap. In the part where the wall is easy to form a gap, the reinforcing mesh shall be used as part of the step. On the facade of the building, the existence of doors and windows will naturally divide the facade into horizontal and vertical small pieces, which will lead to stress concentration, especially in the windows. The corners are more obvious, and cracks are easy to occur in these stress concentrations, and continue to expand and expand. In the past, the general practice was to use steel mesh to seal the edges of rock wool panels at these locations, and a layer of steel mesh should be added to the rock wool panels around the window corners to increase the ability to resist pressure concentration.

3，岩棉板将被保护层覆盖，接头将防水，以减少收缩和温度压力。由于压力导致裂纹损坏是非常偶然的情况。因此，通常在结构中考虑由平行于表面的拉应力引起的裂纹损坏。为了避免拉伸应力过度集中，在铺设岩棉板期间，在岩棉板之间不允许有超过2mm的间隙。板的接缝应在阴阳角分为“T”型和“错误”。

3. The rock wool board will be covered by a protective layer, and the joint will be waterproof to reduce shrinkage and temperature pressure. Crack damage caused by pressure is a very accidental situation. Therefore, crack damage caused by tensile stress parallel to the surface is usually considered in the structure. In order to avoid excessive concentration of tensile stress, no more than 2mm gap is allowed between rock wool boards during the laying of rock wool boards. The joints of plates shall be divided into "T" type and "wrong" type at the internal and external corners.

防止冬季岩棉板出现裂缝，减少墙体的热量损失。在相同的加热条件下，保温后室内空气温度和保温前壁面温度得到改善。夏季，岩棉板外保温系统可以减少太阳辐射的热传导，有效降低太阳辐射与室外气温的综合影响，从而降低室内空气温度和墙内表面温度。更多相关内容就来我们网站http://www.jnhxtcg.com咨询！

Prevent cracks in the rock wool board in winter and reduce the heat loss of the wall. Under the same heating conditions, the indoor air temperature after insulation and the wall temperature before insulation are improved. In summer, the rock wool board external insulation system can reduce the heat conduction of solar radiation, effectively reduce the comprehensive impact of solar radiation and outdoor air temperature, thus reducing the indoor air temperature and wall surface temperature.
