Is rock wool sandwich panels the same as flame retardant panels?

Rock wool sandwich panels are used in the construction industry. With more and more users, more and more people are using it. Today, let's talk about its characteristics:

1. Light weight, the weight per square meter is less than 14kg, which can fully reduce the structural load and reduce the structural cost.

2. Quick installation. The composite panel has light weight, splicing installation and can be cut at will, which determines its easy installation and saves construction time.

3. Fireproof. The surface material and insulation material of the color composite sandwich panels are non-combustible materials, which can fully meet the requirements of fire protection regulations.

4. Durable. Various studies have shown that the shelf life of the color steel plate treated with special coating is 10 to 15 years. After that, the anti-corrosion coating is sprayed every 10 years, and the plate life can reach more than 35 years.

5. Beautiful. The clear lines of the corrugated steel plate are as many as dozens of colors, which can meet the needs of the style of the building and achieve satisfactory results.

6. Thermal insulation. Common thermal insulation materials for this composite board include: rock wool, glass fiber wool, polyethylene, polyurethane, etc., with low thermal conductivity.

Do you know how to define flame retardant board?

Flame retardant panel is also called polyurethane rock wool sandwich board or PU edge-sealed rock wool panel. This rock wool sandwich panel requires GB/T 23932-2009 standard requirements. Polyurethane rock wool sandwich panel has polyurethane as the insulation filling layer and is made of double-color steel plate, single-color steel plate or non-metallic panel. This sandwich board is used in factories, logistics storage, and walls and roof systems of integrated residences.

In terms of production requirements, the bonding strength of polyurethane rock wool sandwich board is not less than 0.09MPa, the flammability of sandwich board needs to reach grade B1, and the bending bearing capacity of sandwich board is not less than 0.5Km/m2 at deflection capacity of Lo/200 (Lo is the distance between supports). The effective width of the board is usually 1000mm, and the length can be customized. A highly continuous sandwich panel production line is required for production. The process consists of cold bending of internal and external galvanized (aluminum-zinc) color steel plates and polyurethane rigid foam coating.

Flame-retardant panels are similar to secondary processing of rock wool panels. They are moisture-proof, insect-proof, sound-proof, lightweight, will not deform when wet or dry, and have thermal insulation effects. They can be nailed and sawed, are simple and convenient to construct, and can be recycled. They are formed in a one-time synthesis in the mold without the need for interface adhesives. If the surface layer of the composite panel is a metal plate, the product's folding resistance is enhanced, the product's fire resistance is improved, the product will not crack or break, and it has wear resistance and a smooth surface quality. It shrinks little and does not become brittle when used at ultra-low temperatures, and is suitable for cold storage, garage doors, etc.
