The rock wool board for exterior wall shall comply with the implementation standard of rock wool board for external thermal insulation of building exterior wall GB T 25975-2010. Rockwool slate wool board is made of basalt and other natural ore as the main raw material, melted into fiber by high temperature, added with appropriate amount of binder, solidified and processed, widely used in shipbuilding, metallurgy, electric power, construction and other industries. Has good insulation and sound insulation. Convenient construction and installation, remarkable energy saving effect, high performance and price ratio. Marine and hydrophobic rock wool insulation boards are added with hydrophobic additives during production, which have good moisture resistance. Marine rock wool board is used for thermal insulation and fireproof partitioning of ships; hydrophobic rock wool board is used for vehicles, mobile equipment, cold storage engineering, air conditioning ducts, and insulation and fire protection in humid environments and applications where moisture is required. The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties. It is mainly used for thermal insulation of building walls and roofs; fire protection and noise reduction of building partitions, firewalls, fire doors and elevator shafts. Features of rock wool board: 1. Appearance quality: The surface is flat, and there must be no scratches or stains that impede practical use. 2. Combustion performance: non-combustible. 3. Thermal load shrinkage temperature: 643 degrees. 4. Hygroscopicity: 3.9%. 5. Organic matter content: 2.9%. Basic parameters of rock wool board: Material: color steel plate, rock wool Apparent density: rock wool 120 (kg/m3) Thermal conductivity: 0.04 (W / (mK)) Maximum operating temperature: 450 (°C) Specifications: 1000*600, 1200*600 (mm) Rock wool board implementation standards: GB Working temperature: 80-450 (°C) Moisture absorption rate: 3.9 (%) The rock wool board for exterior wall shall comply with the implementation standard of rock wool board for external thermal insulation of building exterior wall GB T 25975-2010. 1. Good construction performance. Construction costs are low. It is less harmful to the human body. 2. High acidity coefficient (acidity coefficient is greater than 1.6, so corrosion resistance is high, so the service life is long.) 3. Good tensile and compressive strength and high strength. 4. The product process is complicated, and pleating will increase the pressure resistance and drawing force.
