岩棉板主要用于建筑，是一种外墙保温材料，作为无机外墙保温材料已达到A级防火标准，这带来了前所未有的市场机遇。那么岩棉板建筑时的表层结构满足什么要求呢？

Rock wool board is mainly used in construction. It is a kind of external wall insulation material. As an inorganic external wall insulation material, it has reached the class a fire prevention standard, which has brought unprecedented market opportunities. So what requirements does the surface structure of rock wool board meet?

1、粘贴岩棉板后，应对板的抹灰表面进行表面处理。用不锈钢刮刀在整个表面上涂抹抹灰砂浆（厚度为1-1.5mm），并将其压入岩棉板的表面纤维中。

1. After pasting the rock wool board, the plastered surface of the Board shall be treated. Apply plastering mortar (1-1.5mm thick) on the whole surface with a stainless steel scraper and press it into the surface fiber of rock wool board.

2、抹灰胶应严格按照产品使用说明书进行配置，配置的粘合剂应避免阳光直射，应在2小时内用完。

2. The plaster adhesive shall be configured in strict accordance with the product instructions. The configured adhesive shall be protected from direct sunlight and shall be used up within 2 hours.

3、擦拭层分为两层。层抹灰的厚度为2-3mm，应该先用不锈钢锯齿抹刀抹灰，然后用大抹刀将其弄平，然后在湿的时候将其压入玻璃纤维网布中，直到胶水稍微干燥。安装锚栓并用抹灰胶密封锚栓塑料盘及其周围。层抹灰砂浆可以稍微干燥，第二层抹灰砂浆就可以建造了，其厚度约为2mm，使抹灰层的厚度达到设计要求。

3. The wiping layer is divided into two layers. The thickness of the first layer of plastering is 2-3mm. It should be plastered with a stainless steel serrated spatula, then flattened with a large spatula, and then pressed into the glass fiber mesh when it is wet until the glue is slightly dry. Install the anchor bolt and seal the plastic plate of the anchor bolt and its surroundings with plaster glue. The first layer of plastering mortar can be slightly dried, and the second layer of plastering mortar can be built, with a thickness of about 2mm, so that the thickness of the plastering layer can meet the design requirements.

4、网布的铺设应弄平，拉直，并保持阴角和阳角的垂直度。网格的顶部，底部，左侧和右侧之间应该有重叠，并且重叠宽度不应小于100mm，请勿将玻璃纤维网布直接放在岩棉板的表面上，也不得裸露或擦干。

4. The laying of mesh cloth shall be leveled and straightened, and the verticality of internal and external corners shall be maintained. There should be overlap between the top, bottom, left and right sides of the grid, and the overlap width should not be less than 100mm. Do not put the glass fiber mesh directly on the surface of the rock wool board, and do not expose or dry it.

根据设计要求，应使用冲击钻或电锤钻孔安装锚，钻孔深度应大于锚固深度10mm。在安装过程中，应将锚钉敲打或拧入墙壁，并且圆盘应靠近网的层。检查抹布，并及时用抹灰胶盖住光盘及其周边。

According to the design requirements, the impact drill or electric hammer shall be used to drill and install the anchor, and the drilling depth shall be 10mm greater than the anchoring depth. During installation, anchor nails should be knocked or screwed into the wall, and the disc should be close to the first layer of the net. Check the rag and cover the disc and its periphery with plaster glue in time.

预防措施

preventive measure

1、济南岩棉板厂家提醒您，在使用该板材时要注意雨水，在雨天不能施工。

1. Jinan rock wool board manufacturer reminds you that you should pay attention to rain when using this board, and you can't work in rainy days.

2、为了冷藏，必须添加防潮层。在特别低的温度下，无树脂的岩棉被用作隔热材料，防潮层也必须防火。

2. In order to refrigerate, a damp proof layer must be added. At extremely low temperatures, resin free rock wool is used as heat insulation material, and the damp proof course must also be fireproof.

3、当温度超过特定温度（例如200°C）时，必须在绝缘材料上添加适当的外部保护，以使岩棉板的厚度和堆积密度不变。

3. When the temperature exceeds a specific temperature (such as 200 ° C), appropriate external protection must be added to the insulating material to keep the thickness and bulk density of the rock wool board unchanged.
