When selecting ceramic fiber refractory insulation materials, several key performance indicators must be considered, including maximum service temperature (°C), thermal conductivity (W/(m·K)), compressive strength (MPa), bulk density (kg/m³), and flexural strength (MPa). These properties are interrelated and influence each other, making it essential to follow energy-efficient and practical principles when choosing ceramic fiber products. Proper selection helps avoid potential damage to refractory materials and ensures optimal insulation performance in chemical equipment. Below, we explore how to fully leverage the advantages of ceramic fiber to achieve effective thermal insulation in chemical applications.
01 Maximum Service Temperature
In chemical equipment, it is crucial to ensure that the maximum temperature the ceramic fiber can withstand is higher than the operating temperature of the equipment. This prevents deformation, degradation, and aging of the material under high-temperature conditions.
02 Thermal Conductivity
Thermal conductivity reflects the ability of ceramic fiber to transfer heat and is a key thermophysical property. In chemical equipment, this value can be influenced by factors such as temperature and moisture content. Controlling thermal conductivity is essential for achieving efficient thermal insulation.
03 Compressive Strength
Chemical equipment often subjects insulation materials to pressure loads. Adequate compressive strength ensures that the ceramic fiber maintains structural integrity and stability under these conditions.
04 Bulk Density
Bulk density refers to the weight per unit volume of the insulation material when dried at 110°C and in a loose state. There is an optimal bulk density value at which the material exhibits low thermal conductivity and high insulation efficiency. Selecting ceramic fiber with suitable density helps achieve energy-saving goals in chemical applications.
05 Flexural Strength
Flexural strength indicates the material's ability to withstand bending forces per unit area under operating conditions in chemical environments. Ceramic fiber products are known for their high resilience and strength, maintaining tear resistance both before and after heating, which enhances durability under mechanical stress.
