Taking rock wool composite board as an example, the requirements for rock wool board as thermal insulation material: select flame-retardant board, the density is ≥ 140kg / m3, the thermal conductivity is ≤ 0.04w / m.k, the tensile strength perpendicular to the surface is ≥ 10KPA, the compressive strength is ≥ 40kpa, and the combustion function grade is Grade A.

优选玻璃纤维网布：烟台保温板薄抹灰外墙外保温体系中运用的玻璃纤维网布，由于埋在水泥砂浆中，要求耐碱。根据数据，烟台聚苯板外墙保温体系可到达40-50年的运用寿命。如果运用耐碱玻璃纤维网格布，它将在水泥的碱性环境中提前破坏破碎，这将大大缩短整个体系的运用寿命。因而，有必要选用耐碱玻璃纤维网格布。

Glass fiber mesh is preferred: the glass fiber mesh used in Yantai insulation board thin plastering external wall external insulation system is required to be alkali resistant because it is buried in cement mortar. According to the data, Yantai polystyrene board exterior wall insulation system can reach the service life of 40-50 years. If the alkali resistant glass fiber mesh cloth is used, it will be damaged and broken in advance in the alkaline environment of cement, which will greatly shorten the service life of the whole system. Therefore, it is necessary to choose alkali resistant glass fiber mesh cloth.

粘结砂浆的挑选：由于现场掺入水泥，施工进程中难以操控水泥的质量和配比，增加了施工进程的复杂性。单组分粘结砂浆施工简略。只能通过加水和现场拌和的方法运用，以防止因水泥等资料增加不当而导致粘结砂浆质量下降。施工时尽量选用单组分粘结砂浆。

Selection of bonding mortar: due to the addition of cement on site, it is difficult to control the quality and proportion of cement in the construction process, which increases the complexity of the construction process. Construction of single component bonding mortar is simple. It can only be used by adding water and on-site mixing, so as to prevent the decline of bonding mortar quality due to improper addition of cement and other materials. Single component bonding mortar shall be selected as far as possible during construction.

挑选锚固件：挑选锚固件后，有必要首要进行锚固件的样品施工和拉伸试验。

Selection of anchors: after the selection of anchors, it is necessary to first carry out the sample construction and tensile test of anchors.

2、材料应合理寄存

2. Materials shall be properly deposited

做好施工前的准备工作，做好仓库管理工作。在许多施工现场，常见的是岩棉板进入现场后露天堆积。岩棉板的日晒雨淋非常容易引起板结构变形和收缩变形。

Make preparations before construction and warehouse management. In many construction sites, it is common for rock wool boards to accumulate in the open air after entering the site. The sun and rain of rock wool board are very easy to cause board structure deformation and shrinkage deformation.

3、基层处理有必要合格

3. The treatment of base course must be qualified

对于外保温工程（特别是抹灰层较薄的外保温体系），抹灰层与饰面层之间的尺度误差在很大程度上取决于基层。因而，施工前有必要对基层的尺度误差进行评定。

For external insulation works (especially the external insulation system with thin plastering layer), the scale error between plastering layer and finishing layer largely depends on the base course. Therefore, it is necessary to evaluate the scale error of the base before construction.

4、现场膏体按比例配制

4. The on-site paste is prepared in proportion

粘结料浆在外墙保温岩棉板施工中起着重要作用。比例有必要严厉按照阐明执行，并留意及时性。

Binder slurry plays an important role in the construction of external wall thermal insulation rock wool board. It is necessary to strictly follow the instructions and pay attention to timeliness.

5.岩棉复合板资料尺度的挑选有必要标准合理

5. The selection of data scale of rock wool composite board is necessary and the standard is reasonable

6.正确结构玻璃纤维网布

6. Glass fiber mesh with correct structure

铺贴网格布压入胶结层，外表抗裂砂浆应充沛刮平网格布，但厚度不宜过厚。对于抹灰层较薄的体系，保护层的厚度应不小于3mm，且不大于6mm，以隐藏的网格为准，以充沛发挥网格布反抗温度引起的应力。如果抗裂砂浆太厚，格栅布就不能起到很好的作用，简单造成外表裂缝。门窗洞口及阴阳角四周加钢筋网，一层墙面满铺一层钢筋网。

The grid cloth shall be paved and pressed into the cementation layer, and the anti crack mortar on the surface shall fully scrape the grid cloth, but the thickness shall not be too thick. For the system with thin plastering layer, the thickness of the protective layer shall not be less than 3mm and not more than 6mm, subject to the hidden grid, so as to give full play to the stress caused by temperature. If the anti crack mortar is too thick, the grid cloth can not play a good role and simply cause surface cracks. Reinforcement mesh shall be added around door and window openings and internal and external corners, and a layer of reinforcement mesh shall be fully paved on the wall on the first floor.

7.建议选用条状粘结法粘贴岩棉板

7. It is recommended to use strip bonding method to paste rock wool board

所谓条状粘结法是将砂浆摊铺在整个板材上，然后用锯齿抹子将其摊铺，并将多余的砂浆挂起。该方法施工在处理平整的墙体上，可防止空鼓的发生，不会产生岩棉板的翘曲变形，也可防止因封边不严而渗水、通风、掉落。条带粘结法消耗的砂浆与点粘结法消耗的砂浆几乎相同。

The so-called strip bonding method is to spread the mortar on the whole plate, then spread it with a serrated trowel, and hang the excess mortar. This method can prevent hollowing and warping deformation of rock wool board, and can also prevent water seepage, ventilation and falling due to lax edge sealing. The mortar consumed by strip bonding method is almost the same as that consumed by point bonding method.

8.防止外表砂浆裂缝应留意的问题

8. Problems needing attention to prevent surface mortar cracks

外表抹灰砂浆抹两遍，总厚度操控在3mm～6mm之间。

The surface shall be plastered with mortar twice, and the total thickness shall be controlled between 3mm and 6mm.
