The treatment method of aluminum silicate fiber board in humid environment is as follows:

I. Waterproof and moisture-proof treatment

Surface coating: Spray waterproof agent or moisture-proof coating on the surface of aluminum silicate fiber board to form a dense waterproof film to prevent water vapor from infiltrating into the interior of fiberboard.

Moisture-proof film covering: cover the surface of fiberboard with a layer of moisture-proof film to enhance moisture-proof performance.

Hydrophobic treatment: hydrophobic agent is added in the production process to make the fiberboard have better waterproof performance.

II. Construction and installation

Drying the base material: Before installation, ensure that the surface of the base material is dry, so as to avoid the wet environment from affecting the curing effect of the adhesive.

Sealing treatment: use sealant to seal the joint and edge of fiberboard to prevent moisture from infiltrating.

Avoid long-term immersion: Although aluminum silicate fiber board has certain waterproof performance, it is still not recommended to soak in water for a long time.

III. Environmental control

Ventilation and drying: In humid environment, good ventilation should be maintained to reduce air humidity.

Regular inspection and maintenance: regularly check whether the waterproof layer of fiberboard is intact and repair the damaged parts in time.

IV. Precautions

Avoid mechanical impact: during installation and use, avoid severe mechanical impact on the fiberboard and prevent damage to the waterproof layer.

Prevent moisture absorption and expansion: Long-term exposure to wet environment may lead to moisture absorption and expansion of fiberboard, which will affect the thermal insulation performance, so it should be avoided as far as possible.

Through the above measures, the service life and performance of aluminum silicate fiber board in humid environment can be effectively improved.
