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. 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. 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. 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. 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.
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.

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.
