To avoid yellowing of aluminum silicate ceramic fiber shaped parts, the following measures can be taken:
1. Choose high-quality aluminum silicate ceramic fiber material to ensure that the quality of the material itself meets the standards.
2. During use, avoid contact with chemicals, especially acidic substances and oxidants, which may cause abnormal parts to turn yellow.
3. Use appropriate cleaning methods to regularly clean the dust and dirt on the surface of irregular parts. Mild cleaning agents and soft cloth can be used to clean, avoiding the use of cleaning agents containing acidic components.
4. Avoid high temperatures and prolonged exposure to sunlight, which may cause abnormal parts to turn yellow.
5. Pay attention to the storage environment of irregular parts and avoid humid and high-temperature environments, which may have adverse effects on irregular parts.


In short, to avoid yellowing of aluminum silicate ceramic fiber shaped parts, it is necessary to choose high-quality materials, avoid contact with chemicals, and pay attention to cleanliness and storage environment.
