Ceramic fiber blankets are often used for high temperature equipment in high temperature insulated areas, flanged joints of pipes, valves, etc., for high temperature, heat insulation, sealing and insulation between two planes. Ceramic fiber blankets are available in a variety of materials, often used for aluminum silicate fibers. Non-asbestos and non-delamination are important features. They can be customized to customer requirements and offer deep processing services such as stamping and composite machining, as well as wound washers.
How can we use it to determine if ceramic fiber felt has a big impact on thermal insulation, insulation, sealing, electrical insulation, sound absorption and filtration in high temperature environments?
1. Do not damage the surface sealing surface or sealing line. The sealing performance of the plane depends on the upper face and the lower face. Hydraulic seal performance depends on the lip line associated with the hole or shaft. These parts are soft and flexible, cold and useful. Corrosion, not afraid of aging graphite, rubber, fiber and other vulnerable special materials, so in the process of handling, installation and storage need to provide special protection. Once damaged, it often causes the effect of difficult to use;
2. It cannot be forced to install. The construction period should not be rough and brutal. Forced loading and large movements can damage the original prefabricated structure. This type of installation requires care and caution. Embedding needs to be done step by step. When installing again, balance and symmetry should be emphasized. After the system is opened for use, further observation and fastening work are needed to prevent unnecessary trouble in the system.
Ceramic fiber blanket volume density is very low will affect the performance and use effect of the product itself to determine the extent, because the volume density refers to the weight of the thermal insulation cotton and the overall ratio of the material, the size of the volume density is to determine whether the furnace lining selection is correct indicators, it is an important factor affecting the thermal conductivity. Therefore, when purchasing the product, we should pay attention to this aspect, then again, what factors are related to its bulk density?
There is heat transfer between any object, ceramic fiber blanket is a new material for thermal insulation also need to achieve thermal insulation effect through heat transfer, many people wonder whether the higher the volume weight of the material, the better the performance effect will be, in fact, not necessarily, the thermal conductivity of the fiber blanket decreases with the increase of the volume density, but if the decline is gradually reduced. Then when the density exceeds the corresponding scale, the thermal conductivity will increase. At different temperatures, a small thermal conductivity corresponds to a small volume density, and the volume density corresponding to a small thermal conductivity will increase with the increase of temperature.
In order to reduce the heat dissipation of high temperature industrial furnaces, it is often used as a lining with fiber materials that are not afraid of fire. Among many inorganic fiber materials, ceramic fiber thermal insulation blankets are relatively used and the effect is relatively good.
