The main performance indicators of ceramic fiber refractory insulation materials include maximum service temperature (°C), thermal conductivity (W/(m·K)), compressive strength (MPa), bulk density (kg/m³), and flexural strength (MPa). These performance metrics are interconnected and influence each other. Therefore, when selecting ceramic fiber products, it is essential to adhere to the principles of "energy efficiency and practicality," effectively avoiding actions that could damage the refractory material. This ensures the full utilization of ceramic fiber's advantages and guarantees optimal insulation performance in chemical equipment.
01 Maximum Service Temperature
When applying ceramic fiber in chemical equipment, it is crucial to consider the operating temperature environment. Ensure that the maximum tolerable temperature of the ceramic fiber product exceeds the normal working temperature of the equipment. This prevents deformation, aging, or degradation of the ceramic fiber under high-temperature conditions.
02 Thermal Conductivity
Thermal conductivity reflects the heat transfer capability of ceramic fiber products and is a key thermophysical property. When used in chemical equipment, the thermal conductivity of ceramic fiber can be influenced by factors such as operating temperature and moisture content. It serves as a critical indicator for achieving effective thermal insulation in chemical applications.
03 Compressive Strength
In chemical equipment applications, ceramic fiber products must be able to withstand corresponding pressure loads. Adequate compressive strength ensures structural stability and maintains insulation integrity under mechanical stress.
04 Bulk Density
Bulk density refers to the weight per unit volume of the insulation material after being dried at 110°C in a loose state. There exists an optimal bulk density value at which the material exhibits low thermal conductivity and superior insulation performance. To meet energy-saving and insulation goals in chemical equipment, it is important to select ceramic fiber products with an appropriate bulk density.
05 Flexural Strength
Flexural strength indicates the maximum bending moment per unit area that ceramic fiber can withstand under mechanical load in chemical equipment environments. Due to the inherent properties of ceramic fiber, these products demonstrate high resilience, high strength, and resistance to tearing both before and after heating, ensuring durability under flexural stress.
