Aluminium Silicate Blanket Features

Kerui uses high-purity aluminum silicate (Al2SiO5) fiber to make it. So, you can use it widely for thermal insulation protection in industrial furnaces, boilers, heat treatment equipment and chemical equipment.

  • High temperature resistance: Kerui aluminium silicate fiber can withstand extremely high temperatures, up to 1403°C. Moreover, some specially treated products can even withstand higher temperatures.
  • Low thermal conductivity: ceramic blanket can effectively isolate heat energy even in high temperature environments. This can help industrial equipment reduce energy losses and improve energy efficiency.
  • Chemical stability: the aluminum silicate fiber blanket has good chemical stability. So, it does not react easily with most chemicals and is highly corrosion-resistant.
  • Physical stability: even at high temperatures and frequent temperature changes, it maintains a good physical structure without significant shrinkage.
  • Sound insulation performance: Kerui aluminium silicate blanket also has a certain sound absorption effect. That is to say, this helps reduce industrial noise.
  • Easy installation: customers can easily cut and arrange fiber blankets in the required areas. In other words, it is highly adaptable and easy to install.
  • Environmental protection: Kerui’s new aluminum silicate fiber blanket has less impact on the environment during production and use. So, if you are interested in environmentally friendly ceramic fiber products, please feel free to contact us or follow us on Pinterest for more information.

Methods to Extend the Service Life of Aluminum Silicate Fiber Blanket

If you want to apply aluminum silicate blankets to industrial equipment to extend its service life, you may consider the following methods:

  • Proper installation and fastening: make sure the aluminum silicate blanket is installed correctly and securely fastened to the equipment. And ensure that the aluminum silicate fiber blanket will not be damaged or deformed during the installation process.
  • Use the appropriate temperature range: aluminum silicate blankets need to be used within their specified temperature range. Exceeding its heat-resistant temperature range can cause material aging, failure or deformation.
  • Prevent mechanical damage: protect the aluminum silicate insulation from mechanical damage such as mechanical vibration, impact or scratching. When installing and maintaining equipment, take care to protect the aluminum silicate fiber blanket from scratches or breakage.
  • Avoid over-stretching or squeezing: avoid over-stretching or squeezing the aluminum silicate blanket during use to avoid damaging its structure and performance. Or you can contact Kerui company to get a detailed installation guide.
  • Regular inspections and maintenance: regularly check the condition of your aluminosilicate fiber to ensure its integrity and performance. Pay attention to it for wear, cracks or other damage. If you find any problems, replace or repair them promptly.
