How about the fire performance of rock wool color steel sandwich panel?

Sandwich panels are commonly used in industrial plants. Rock wool sandwich panel has obvious advantages such as light weight, heat insulation, sound absorption, good sealing performance, convenient construction, short cycle, low comprehensive cost, bending resistance, corrosion resistance and beautiful appearance. A new type of fireproof board that is stronger. The weight is less than 14kg per square meter, which can fully reduce the structural load and reduce the structural cost. The color steel rock wool sandwich panel is light in weight, can be assembled and cut freely, and is easy to install, which can greatly improve efficiency and save time. The surface material and thermal insulation material of the fireproof color composite sandwich panel fully meet the requirements of fireproof specifications.

Rock wool sandwich panel has excellent fireproof performance, and the raw materials, production process and formula used make it have good fireproof performance. Tests have shown that it is highly fire resistant. According to the thermal conductivity of rock wool = 0.043w\u002Fm2k and the thickness of the rock wool core, the thermal insulation performance of the rock wool sandwich panel is calculated. The results show that rock wool sandwich panels have obvious sound absorption and heat insulation effects, and can significantly reduce noise transmission. In addition, after using rock wool roof panels, the indoor sound caused by the impact of rain and hail on the roof steel plates of buildings is also significantly weakened.

The service life of the color steel sandwich panel should be very long, because if it is used on the roof, it will not accumulate water, and it will dry quickly, so there will be no rust and corrosion problems due to moisture. Generally speaking, there is no problem in using it for more than ten years. Of course, it depends on what color color steel sandwich panel you use. Materials vary in thickness, bulk density and service life. Many outdoor color steel plates will develop and change due to pollution and changes in climatic and environmental conditions. Once the organic bonded coating becomes powder due to long-term exposure, moisture will make it swell and loosen, and it will gradually lose its important role of self-protection as time goes by. At this time, it needs us to repaint, which can effectively extend the service life of the rock wool color steel sandwich panel, and it can be used for 30 to 40 years.
