Proper installation of aluminum silicate fiber blanket is the key to ensure its thermal insulation performance and service life. The following are detailed installation steps and precautions:
Inspection materials: ensure that the specifications, dimensions and temperature resistance grade of aluminum silicate fiber blanket meet the design requirements.
Cleaning the surface: the surface of the construction site should be clean and dry, free of oil, dust and other impurities.
Protective measures: As the fibers of the fiber blanket may irritate the skin, the construction personnel should wear protective gloves, masks and long-sleeved clothes.
According to the design size, use a ruler and scissors to cut the fiber blanket neatly.
Pay attention to avoid excessive stretching or damage of fiber blanket when cutting.
The fiber blanket is pre-compressed, and the compression rate is generally 15%~20%.
The pre-compressed fiber blanket should maintain a uniform thickness to ensure the flatness after installation.
Anchor nail fixation:
Welding anchor nails on the furnace wall, the nail head needs to be covered with a layer of thermal insulation rock wool with a thickness of about 15 ~ 20 mm.
Fix the compressed fiber blanket on the anchor nail to ensure firm fixation.
Paste method:
Before construction, the bonding surface shall be divided and scribed according to the size of each bundle of fiber blankets.
Use a special adhesive to evenly spread on the back of the fiber blanket, and the spreading area of the adhesive should not be less than 50%.
Stick the fiber blanket on the construction surface, and press it tightly with a wooden trowel to ensure the firm paste.
Joints should be closely combined, and if there are gaps in transverse joints, they should be filled with the same material.
Longitudinal lap seam should be placed above the pipeline, and the lap width should be not less than 10 mm.
After the installation is completed, check whether the surface of the fiber blanket is flat. If there is any unevenness, it can be leveled with wooden tools.
Avoid moisture: the fiber blanket is not waterproof, so it should be avoided to be used or stored in a humid environment to prevent moisture from affecting the heat insulation performance.
Prevention of mechanical damage: the fiber blanket is not wear-resistant and collision-resistant, so it should be avoided to trample and crush after installation.
Regular inspection: the surface condition of the fiber blanket should be inspected regularly during use, and the damage or deformation should be found and treated in time.
Ventilation: when used in a confined space, it is necessary to strengthen ventilation to avoid the impact of dust accumulation on human health.
Through the above steps and precautions, the correct installation and long-term effective use of aluminum silicate fiber blanket can be ensured.
