The service life and retention time of aluminum silicate fiber paper in high temperature environment depend on many factors, including service temperature, environmental humidity, contact with corrosive substances and the quality of the material itself. The following are specific instructions:

I. Operating temperature

Continuous use temperature: The continuous use temperature of aluminum silicate fiber paper can usually reach 1000℃. At this temperature, the performance of the material is relatively stable and it can maintain good heat insulation effect for a long time.

Short-term service temperature: In a short time (such as several hours), aluminum silicate fiber paper can withstand temperatures as high as 1260℃. However, this high-temperature use will accelerate the aging and performance degradation of materials.

II. Service life

Long-term use: In a suitable temperature range (such as below 1000℃), the service life of aluminum silicate fiber paper can usually reach 5-10 years. It depends on the quality of the material and the use environment.

High temperature environment: If exposed to the environment close to its limit temperature (such as 1260℃) for a long time, the service life of the material will be significantly shortened, and the performance may decline within 1-2 years.

III. Environmental factors

Humidity: aluminum silicate fiber paper has certain hygroscopicity, and the humid environment will accelerate its aging and reduce its heat insulation performance. Therefore, when used in humid environment, it is necessary to take moisture-proof measures.

Corrosive substances: In the environment containing corrosive substances (such as hydrofluoric acid, phosphoric acid and concentrated alkali), the service life of materials will be shortened. In this case, it is recommended to use specially treated aluminum silicate fiber paper.

IV. Quality of materials

High-purity and zirconium-containing aluminum silicate fiber paper: High-purity and zirconium-containing aluminum silicate fiber paper have better high-temperature resistance and longer service life. For example, the use temperature of zirconium-containing fiber paper can reach 1350℃, and its service life is longer in high temperature environment.

Ordinary type: Ordinary aluminum silicate fiber paper has a low service temperature (usually less than 1000℃) and a relatively short service life.

V. Suggestions in practical application

Regular inspection: when used in high temperature environment, it is recommended to regularly check the performance of materials and replace damaged parts in time.

Protective measures: In high temperature and humid environment, aluminum silicate fiber paper can be coated to improve its corrosion resistance and moisture absorption resistance.

To sum up, aluminum silicate fiber paper can be used for a long time in high temperature environment, but its service life is affected by many factors such as service temperature, environmental humidity and material quality. Under suitable conditions, it can be used for 5-10 years, but in extreme high temperature or corrosive environment, its service life will be significantly shortened.
