Application of green carborundum GC powder in thermal insulation materials
The application of green carborundum GC powder in thermal insulation materials is mainly reflected in the following aspects:
1. Thermal insulation filler
Green carborundum GC powder is often used to prepare high-performance thermal insulation materials due to its low thermal conductivity, high temperature resistance and chemical stability. For example, green carborundum GC F1000 with a purity of 99% can be directly used as a filler for thermal insulation. By adjusting the particle size distribution and filling ratio, the overall thermal conductivity of the material can be significantly reduced to meet the insulation needs of high-temperature equipment such as kilns and pipelines.
2. High temperature stability and structural support
Green carborundum GC powder can still maintain structural stability in a high temperature environment of 1600-2200°C, and its low thermal expansion coefficient can reduce the risk of cracking of thermal insulation materials due to sudden temperature changes. This feature makes it a key additive for the thermal insulation layer of high-temperature industrial equipment (such as metallurgical furnaces and glass melting furnaces).
3. Composite insulation material reinforcement
In lightweight insulation materials (such as ceramic fiber, aerogel), green carborundum GC powder can improve performance in the following ways:
Mechanical strengthening: as a rigid filler to improve the compressive strength of the material.
Corrosion resistance: enhance resistance to molten metal or corrosive gas.
Thermal radiation reaction: reflect thermal radiation through the surface of the powder particles, reducing the efficiency of heat conduction.
4. Application in energy-saving and environmental protection fields
Green carborundum GC powder-based insulation materials are widely used in:
Building exterior wall insulation system
New energy vehicle battery pack insulation protective layer
Solar thermal power generation system heat storage unit
Note: The specific application of green carborundum GC powder needs to be optimized according to the temperature range, chemical environment and physical performance requirements of the insulation scene. The applicability of products with different purity (such as 99%) and particle size (such as F1000) is significantly different.
