How to use aluminum foil rock wool blanket pipeline protection? Aluminum foil rock cotton blanket is a type of blanket made by overlaying aluminum foil on top of rock cotton blanket. It can be divided into single-sided aluminum foil and double-sided aluminum foil; Combined with the user's usage scenarios and functional requirements, the density of aluminum foil rock cotton blankets varies and their functions are differentiated. Rosewool Insulation Refractory Co.,Ltd aluminum foil rock cotton blanket combines the insulation and fire resistance of rock wool with the moisture-proof and reflective heat radiation characteristics of aluminum foil. It is widely used in pipeline protection, especially suitable for scenarios that require insulation, fire prevention, and may come into contact with humid environments.

Key construction issues for aluminum foil rock wool blanket pipeline protection

1. Moisture and Waterproof: Although rock wool is hydrophobic, prolonged immersion can still affect its performance. Ensure that the materials are dry during and after construction. Outdoor or humid environment construction should complete the outer protective layer as soon as possible to prevent rainwater from entering.
2. Strict sealing: The quality of aluminum foil tape adhesion is the key to ensuring insulation and moisture resistance. It must be compacted, leveled, without bubbles or openings. All seams should be covered. The insulation material should be in close contact with the pipeline wall and between each layer of insulation material to minimize gaps and reduce convective heat loss.
3. Security protection:
When cutting rock wool, small fibers will be generated, so it is necessary to take personal protective measures.
The workplace should have good ventilation.
Clean up the site promptly after construction to avoid fiber scattering.
4. Layered insulation: When the thickness of the insulation layer is designed to be thick (usually exceeding 8-10cm per layer), multiple layers of staggered wrapping should be used to reduce joint heat loss and improve structural stability.
5. Support and spacing: For horizontal large pipelines, the lower insulation layer may sink due to its own weight, and insulation support rings (usually made of galvanized steel plates) need to be installed at the bottom of the pipeline to prevent the insulation layer from collapsing.
