In practical application, rock wool boards first need to be processed into suitable panels or pipe shells based on the boiler's shape (such as cylindrical furnace bodies, square furnaces, and pipe joints). Then, the installation is completed through the steps of "base fixing - rock wool laying - sealing protection": First, clean the oil stains and rust on the outer surface of the boiler to ensure the base is flat. For flat parts of the furnace body, use adhesives to attach the rock wool boards; for irregular parts such as pipes and corners, wrap them with rock wool pipe shells and use high-temperature-resistant anchor bolts for auxiliary fixation (to prevent falling off due to long-term vibration). Second, fill the gaps at the joints of the panels with rock wool strips to avoid forming "thermal bridges" or flame penetration channels. Finally, install a metal protective plate (such as galvanized steel plate) on the outer side of the rock wool boards to further enhance impact resistance and sealing performance, while preventing rock wool fibers from falling off due to high temperatures or air flow.
What are the core functions of rock wool boards?
Its core fire protection functions are reflected in three aspects: First, blocking flame spread. As Class A non-combustible materials, rock wool boards can directly prevent flames from spreading outward in scenarios such as local sparks or fuel leakage fires that may occur in the boiler, avoiding the fire from affecting surrounding equipment or factory structures. Second, isolating high-temperature transmission. When the boiler is in operation, the furnace body temperature can reach several hundred degrees Celsius. With a low thermal conductivity (≤0.044W/(m·K)), rock wool boards can effectively reduce the transmission of the furnace surface temperature to the external environment, controlling the temperature of the outer metal protective plate within a safe range (usually ≤60℃). This prevents flammable materials nearby (such as cables and thermal insulation cotton) from being ignited by high temperatures and protects operators from scalding. Third, withstanding high-temperature deformation. High-quality rock wool boards can maintain structural stability at temperatures above 700℃ without softening or pulverizing. Even if the boiler experiences short-term overheating, they can still maintain the fire protection effect, buying time for fault detection and emergency handling.
What should be noted during the usage process?
In addition, in view of the special working conditions of factory boilers, two points should be noted during application: First, select high-density rock wool boards (bulk density ≥150kg/m³), which have stronger compression resistance and vibration resistance, and can adapt to the slight vibrations of the boiler during operation, avoiding cracking of the boards after long-term use. Second, ensure that the rock wool boards comply with industrial high-temperature resistance standards (such as GB/T 11835-2019) and do not contain volatile harmful substances, preventing the release of gases at high temperatures that may pollute the workshop environment or corrode boiler equipment, and truly achieving the dual effects of "safe fire protection + long-term protection".
