说夹芯板出现裂痕如何处理
How to deal with cracks in sandwich panels
1、岩棉夹芯板采用微拉抗裂砂浆或聚合物砂浆，粘结强度高，收缩变形小，弹性低。由于其质地柔软，抗裂砂浆的厚度应为25-30mm。
1. Rock wool sandwich board adopts micro tensile crack resistant mortar or polymer mortar, which has high bonding strength, small shrinkage deformation and low elasticity. Due to its soft texture, the thickness of crack resistant mortar shall be 25-30mm.
2、为了减少收缩和温度应力，岩棉夹芯板的保护层应分片维护接缝，接缝处应做防水处理。
2. In order to reduce shrinkage and temperature stress, the protective layer of rock wool sandwich board shall maintain the joint in pieces, and the joint shall be waterproof.
3、岩棉夹芯板的钢网可以增强结构层与保温层和保护层的邻接性；另一方面，可以防止保护层和装饰层的收缩应力和应力集中，从而减少和防止裂缝的发生。岩棉夹芯板厂家表示，墙体容易开裂的部位安装一些钢筋网。
3. The steel mesh of rock wool sandwich board can enhance the adjacency of structural layer, thermal insulation layer and protective layer; On the other hand, it can prevent the shrinkage stress and stress concentration of the protective layer and decorative layer, so as to reduce and prevent the occurrence of cracks. The manufacturer of rock wool sandwich panel said that some reinforcement mesh should be installed at the parts where the wall is easy to crack.
岩棉夹芯板厂家说夹芯板生锈的原因
The reason why the rock wool sandwich board is rusty
岩棉夹芯板含有铁。由于长时间暴露在风吹日晒雨淋中，外涂层不可避免地会受到损坏。受损部位一旦与酸、碱和溶剂接触，就会发生化学反应，生成氧化铁，氧化铁会生锈，严重腐蚀会出现孔洞。
Rock wool sandwich panels contain iron. Due to long-term exposure to wind, sun and rain, the outer coating will inevitably be damaged. Once the damaged part comes into contact with acid, alkali and solvent, it will undergo chemical reaction to form iron oxide, which will rust, and serious corrosion will lead to holes.
在雨季或潮湿的地方，岩棉夹芯板长期使用会生锈。一旦下雨，屋顶上的铁锈就会受到环境的氧化分化和酸碱雨的影响。雨水会顺着岩棉夹芯板流下，出现腐蚀迹象。随着时间的推移，屋顶会被广泛腐蚀。此外，在施工过程中，由于施工人员的疏忽，外涂层被破坏，岩棉夹芯板也可能生锈。因此，在施工过程中，施工人员一定要注意细心施工，注意不要损坏外涂层。
In rainy seasons or wet places, rock wool sandwich panels will rust after long-term use. Once it rains, the rust on the roof will be affected by the oxidative differentiation of the environment and acid-base rain. Rain water will flow down the rock wool sandwich panel, showing signs of corrosion. Over time, the roof will be widely corroded. In addition, during the construction process, due to the negligence of construction personnel, the outer coating is damaged, and the rock wool sandwich board may also rust. Therefore, in the construction process, the construction personnel must pay attention to careful construction and pay attention not to damage the outer coating.
