In addition to the influence of its own chemical composition and production quality, the use temperature of ceramic fiber products in the daily production environment is also affected by factors such as impurity composition, humidity, masonry method, and working system.
01 Influence of impurity components on service temperature
Obviously, the more impurities, the relative reduction of the main components of aluminum oxide and silicon dioxide, and the corresponding use temperature will be reduced. SUNTHERM ceramic fiber products are white in color and less impurities, fire-resistant and high-temperature resistant, and have a long service life.
02 The effect of humidity on operating temperature
90% of ceramic fiber materials are pores, which is the main reason for their ability to insulate heat. The thermal conductivity of water at 0°C is 0.52w/m.k. If the water in the fiber freezes into ice, the thermal conductivity of ice is 2.32w/m.k, and the thermal conductivity of water is nearly 20 times greater than the thermal conductivity of air under the same conditions of 0.0247w/m.k , ice is 94 times that of air under the same conditions! Therefore, for thermal insulation projects, the humidity in the environment where ceramic fiber products are used must be strictly controlled to ensure the thermal insulation performance of ceramic fibers. In the rainy season or in humid environments, SUNTHERM high-temperature hydrophobic blankets can be used, with a hydrophobic rate of 99%. , can resist the influence of humidity on the thermal conductivity and temperature of ceramic fibers.
03 Influence of masonry method on service temperature
Generally speaking, the thermal conductivity of the ceramic fiber tiling method is lower than that of the stacking method, and the use temperature of the tiling type is 50°C higher than that of the stacked type.
04 The influence of the working system on the operating temperature
The working system is divided into two types: continuous and intermittent. Under normal circumstances, the operating temperature of the continuous operation kiln is 50 °C lower than the operating temperature of the intermittent operation kiln.
SUNTHERM has been developing for 29 years and is a professional ceramic fiber manufacturer integrating production, R&D and engineering development.
