濟南巖棉板裂縫有幾個原因：

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

1.保護層和隔熱層之間的粘合強度低或存在空的巖棉板。

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

2.由于門窗入口和出口處的應力集中，保護層和飾面層有缺陷。

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.巖棉板的鋪設與溫度應力變形之間存在差距。

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

濟南巖棉板防裂措施：

Anti-cracking measures for Jinan rock wool board:

1，采用微細緊固抗裂砂漿或聚合物砂漿，粘接強度高，收縮變形小，無彈性。由于巖棉板具有柔軟的質地，因此防裂砂漿的厚度優選為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，采用鋼絲網或鋼絲網夾層巖棉板加固層，一方面將鋼網或加強結構層與保溫層和愛層相鄰，另一方面或分散的愛的收縮應力層和面層層壓力集中，從而達到減少和避免間隙呈現的目標。在壁易于形成間隙的部分中，須采用加強網的步驟的一部分。在建筑物的立面上，門和窗口的存在自然地將立面分成水平和垂直的小塊，這會導致應力集中，特別是在窗戶中。拐角更加明顯，在這些應力集中容易產生裂縫，并且不斷擴大和擴大。在過去，一般的做法是使用鋼絲網在這些位置密封巖棉板的邊緣，并且應該在窗戶角落周圍的巖棉板上添加一層鋼網以增加抵抗壓力集中的能力。

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，巖棉板將被保護層覆蓋，接頭將防水，以減少收縮和溫度壓力。由于壓力導致裂紋損壞是非常偶然的情況。因此，通常在結構中考慮由平行于表面的拉應力引起的裂紋損壞。為了避免拉伸應力過度集中，在鋪設巖棉板期間，在巖棉板之間不允許有超過2mm的間隙。板的接縫應在陰陽角分為“T”型和“錯誤”。

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.

防止冬季巖棉板出現裂縫，減少墻體的熱量損失。在相同的加熱條件下，保溫后室內空氣溫度和保溫前壁面溫度得到改善。夏季，巖棉板外保溫系統可以減少太陽輻射的熱傳導，有效降低太陽輻射與室外氣溫的綜合影響，從而降低室內空氣溫度和墻內表面溫度。更多相關內容就來我們網站http://www.km6lz.com咨詢！

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.
