Rock wool boards stand as a core insulation material for power plant facilities, leveraging their exceptional high-temperature resistance, fire protection, thermal insulation, and chemical stability to address the complex operational demands of power plants—characterized by high temperatures, high humidity, and multiple corrosive media. They provide crucial support for the safe operation of equipment, energy consumption control, and safe production.
Applications
Rock wool boards align perfectly with the core requirements for insulation materials in power plant scenarios, which are "high-temperature resistance, fire prevention, strong thermal insulation, and corrosion resistance." Their key performance attributes are as follows: They boast a wide temperature resistance range—ordinary rock wool boards can be used continuously at 300-400°C, while specialized high-temperature rock wool boards (such as basalt rock wool) can withstand temperatures above 600°C, covering the operating conditions of most high-temperature equipment in power plants (e.g., boiler flues, steam pipelines, and turbine casings, where medium temperatures typically range from 200-550°C). Additionally, they exhibit low thermal shrinkage—under rated high temperatures, the thermal shrinkage rate of rock wool boards is ≤5% (per GB/T 11835-2019 standard), ensuring they do not easily deform or crack due to high temperatures over long-term use, thus preventing insulation layer failure and heat leakage.
In terms of thermal insulation performance, rock wool boards have a low thermal conductivity—at room temperature (25°C), their thermal conductivity is ≤0.040 W/(m·K), and it remains as low as ≤0.160 W/(m·K) under high-temperature conditions (400°C). This means they can effectively block heat loss from high-temperature media inside equipment or prevent the impact of low-temperature external environments on the interior of equipment (e.g., pipeline anti-freezing in winter). Their stable closed-cell structure, with a porosity of over 90% formed by three-dimensionally interwoven rock wool fibers (mostly closed pores), significantly reduces convective heat transfer of air, further enhancing thermal insulation effects. This makes them particularly suitable for scenarios in power plants that require "high-efficiency heat preservation," such as long-distance steam pipelines and boiler furnaces.
In terms of fire safety, rock wool boards are Class A non-combustible materials. They do not burn or release toxic gases when exposed to fire (only a small amount of harmless water vapor is produced), effectively blocking the spread of fires—a critical feature for power plants, which have a high fire risk due to the presence of fuel oil, cables, and high-temperature media; flammable insulation materials would exacerbate fire disasters. Even under high fire temperatures (e.g., above 800°C), rock wool boards only shrink slightly and do not produce molten drips, avoiding secondary fire risks caused by drips igniting cables or equipment below.
| Building Materials | Fire Performance Class | Fire Resistance Rating | Characteristics When Burning | Applicable Scenarios |
|---|---|---|---|---|
| Rock Wool Board | Class A1 (Non-combustible) | 1-4 hours | Does not burn, maintains structural stability | Wall insulation, fire barriers |
| Expanded Polystyrene (EPS) | Class B2 (Combustible) | 0.1-0.3 hours | Releases toxic fumes, fast fire spread | Low-rise buildings (with fire protection) |
| Polyurethane Foam (PU) | Class B3 (Flammable) | <0.1 hours | Highly flammable, releases toxic gases | Restricted non-exposed uses |
| Glass Wool Board | Class A1 (Non-combustible) | 0.5-2 hours | Stable at high temperatures | Duct insulation, partition walls |
