The service life of diatomite insulation brick is affected by many factors, including the use environment, temperature and construction quality. The following is the detailed information about its service life:

I. Service life range

Building thermal insulation field: In the building thermal insulation field, the service life of diatomite thermal insulation brick can usually reach 10-20 years. This material has good durability and is not easy to age or damage.

Field of industrial furnaces: In industrial furnaces, the service life of diatomite insulation bricks is generally 5-10 years. The specific service life depends on the operating temperature and operating conditions of the furnace. For example, in an environment with a temperature below 900℃, its service life is longer.

II. Factors affecting service life

Temperature: The fire resistance of diatomite insulation brick is generally around 1250℃-1280℃, but the actual use temperature is usually less than 900℃. In high temperature environment, its performance may gradually decline.

Ambient humidity: Diatomite insulation brick has low water absorption (less than 10%), but its strength may be affected in humid environment. Therefore, it is recommended to use it in a dry environment.

Construction quality: The installation quality in the construction process will also affect the service life. For example, the gap between bricks should be tightly filled during construction to avoid damage caused by thermal expansion and cold contraction.

III. Performance in practical application

In building insulation, diatomite insulation brick can effectively keep indoor temperature stable and reduce heat loss, thus reducing energy consumption. It has long service life and reduces the environmental pollution caused by repeated decoration.

In industrial furnaces, diatomaceous earth thermal insulation brick can effectively reduce the heat loss of the furnace body and improve the energy utilization efficiency. Its service life depends on the specific operating conditions of the furnace, such as the frequency and amplitude of temperature fluctuation.

IV. Maintenance recommendations

Regularly check whether there are cracks or damage on the surface of insulation brick, and repair it in time.

Avoid long-term use in humid environment to prevent water absorption from reducing strength.

In high temperature environment, it is suggested to adopt multi-layer insulation structure to prolong service life.

To sum up, diatomite insulation brick can be used for 10-20 years in the field of building insulation and 5-10 years in industrial furnaces. Its service life is affected by factors such as temperature, humidity and construction quality, so it is suggested to use and maintain it reasonably to prolong its
