• First, natural mineral raw materials such as basalt are melted in a high-temperature furnace, transforming them into a liquid state.
• Then, the liquid rock is spun into fibers using a high-speed centrifugal device.
• Next, binders and dust-proofing oil are added to bond the fibers together and enhance their stability and dust-proofing properties.
• Then, the fibers are laid out using a roller-collecting and oscillating belt, and the fiber arrangement is altered by equipment to create a three-dimensional structure, increasing the strength and stability of the board.
• Finally, the board is cured and shaped to form a rock wool board.
Specifications and Thickness: Common rock wool board specifications are 1200mm × 600mm, with thicknesses ranging from 20mm to 200mm. Furthermore, the density of rock wool boards typically ranges from 80kg/m³ to 200kg/m³, suitable for various applications.
