Refractory ceramic fiber blanket is a multi-purpose insulating material with good high temperature resistance and excellent thermal insulation properties. It is widely used in various high temperature equipment such as furnaces, heat treatment equipment, hot blast stoves, and high temperature pipelines. However, there are still some things that need to be paid attention to during use to ensure that it is efficient and durable. Let's share with you the specific usage precautions.
1. Dry before use
Ceramic fiber blankets may absorb a certain amount of moisture when stored and transported, which will affect its insulating properties. Therefore, be sure to dry the blanket before use to ensure its surface is dry and prevent bubbles and micro-cracks. Under normal circumstances, it is recommended to preheat the blanket at a temperature of about 200°C for 2 hours to achieve the drying effect.
2. Pay attention to the operating temperature
The service temperature of ceramic fiber blankets is generally above 1000°C, but this does not mean that it can be used casually. The usage temperature of the blanket should be selected according to its product specifications to ensure that it works within the normal range. At the same time, during use, try to avoid applying excessive thermal stress to the blanket to avoid cracking or deformation.
3. Avoid mechanical damage
Ceramic fiber blankets have excellent flexibility and elasticity, but are also fragile and susceptible to mechanical damage. Therefore, during transportation, installation and use, you should try to avoid violent collision or pulling on the blanket to prevent it from being damaged.
4. Pay attention to moisture-proof
Although the ceramic fiber blanket has a weak ability to absorb moisture, if it is exposed to a humid environment for a long time, it will gradually absorb moisture and destroy its insulation performance. Therefore, during storage, you should avoid placing the blanket in a humid environment. It is recommended to place it in a dry and ventilated place.
5. Avoid contact with chemicals
During the use of ceramic fiber blankets, contact with chemicals should be avoided as much as possible. Substances such as certain acids, alkalis, and solvents can cause chemical reactions on the surface of ceramic fiber blankets, thereby destroying their fire-resistant properties. Therefore, contact with it should be avoided as much as possible during use.
In summary, as a high-temperature fire-resistant insulating material, ceramic fiber blankets require very important precautions when using them. Only by following the above-mentioned standard steps can we ensure its efficient, stable and safe operation and ensure the long-term stable operation of the equipment.
