High temperature glass wool roll felt for power plants: high temperature resistance, A-level fire resistance, vibration resistance, energy saving and consumption reduction
High temperature glass wool roll felt for power plants is a specialized insulation material developed for the insulation needs of high-temperature equipment and pipelines in the power industry. Using natural ores such as quartz sand and feldspar as raw materials, they are melted at high temperatures, blown into fibers by centrifugal spraying, and then combined and solidified with special high-temperature binders. The fibers are slender, uniform, and elastic, with excellent high temperature resistance and chemical stability. They are widely used for insulation and heat preservation of equipment such as boilers, steam turbines, steam pipelines, flue gas ducts, and dust collectors in the fields of thermal power, thermoelectric power, and nuclear power.
core advantage
1. Excellent high temperature resistance performance
Continuous use temperature can reach * * 350 ℃ * *, short-term temperature resistance * * 450 ℃
Using a special high-temperature adhesive, there is no shrinkage deformation in high-temperature environments, and the insulation performance is stable
2. A-level non combustible fire protection
Through national fire prevention testing, the combustion performance has reached * * A2 level
Does not burn or release toxic smoke in the event of fire, in compliance with the strict fire safety regulations of power plants
3. Excellent insulation and energy saving
Thermal conductivity as low as * * ≤ 0.039 W/(m · K) * * (at 70 ℃)
Effectively reduce heat loss and improve thermal efficiency. Actual engineering cases have shown that adopting high-quality insulation solutions can reduce the heat loss rate of pipeline networks by more than 7 percentage points
4. Efficient sound absorption and noise reduction
The porous fiber structure has excellent sound absorption performance, with a noise reduction coefficient (NRC) of over 0.85
Effectively absorb the mid to low frequency noise generated during equipment operation and improve the working environment
5. Anti vibration performance
Fiber is flexible and elastic, which can buffer mechanical vibrations generated by equipment start stop and medium flow
Avoid cracking and detachment of hard insulation materials caused by vibration
6. Convenient construction
Roll felt is flexible and can be cut to fit the surface of pipe bends, valves, and irregular equipment
Suitable for large-scale and high-efficiency insulation construction needs in power plants

common problem
Q
What are the main types of building insulation materials? What are the advantages and disadvantages of each?
A
Advantages: Good fire resistance (Class A non combustible), good breathability, and high stability.
Disadvantages: Slightly higher thermal conductivity than organic materials, higher water absorption rate, and easy generation of fiber dust during construction.
Organic insulation materials (such as EPS polystyrene board, XPS extruded board, PU polyurethane):
Advantages: low thermal conductivity, good insulation effect, light weight, and convenient construction.
Disadvantages: The fire rating is mostly B level (requiring the addition of flame retardants), it is prone to deformation at high temperatures, and its durability is slightly poor.
Composite insulation materials (such as integrated insulation board, vacuum insulation board):
Advantages: Excellent comprehensive performance, high construction efficiency, and some can achieve Class A fire protection.
Disadvantages: High cost and strict requirements for the flatness of the base layer.
Q
How to choose insulation materials suitable for the project?
A
Fire prevention requirements: Grade A materials are required for high-rise buildings (>100m); Low level B1 (flame retardant) is available.
Climate conditions: In extremely cold regions, materials with low thermal conductivity (such as PU, XPS) are preferred; Low water absorption is required in humid environment (such as XPS, foam glass).
Base type: Concrete walls often use boards; Complex shapes can be coated with polyurethane or insulated mortar.
Economy: EPS has the lowest cost; Vacuum insulation board is expensive but thin.
Policy and regulations: B2 level materials are prohibited in some areas, and local standards need to be consulted.
