ROCK WOOL PANEL
The production of rock wool sandwich panel is mainly based on basalt as raw material, then melted at high temperature for a long time, and then processed by a series of processes to produce inorganic fibers. This product has the characteristics of light weight, non-combustible, good sound absorption, low thermal conductivity and good chemical stability.
Therefore, this kind of rock wool sandwich panel can be divided into waterproof rock wool panel, water-repellent rock wool panel, fire-proof rock wool panel and other types. The water-repellent function of rock wool panel is that it adds water-repellent additives to it, so it has good moisture-proof performance. Rock wool panel is mainly used in the shipping industry for ship thermal insulation, fire prevention and so on. Water-repellent rock wool panel has moisture-proof function. The special functions of water-repellent and temperature-exhausting are suitable for use in dark, humid and rainy environment. When producing marine rock wool board insulation panel and water-repellent insulation panel, water-repellent additives are added at the same time. Both of them have good moisture-proof performance. Because of these advantages, rock wool board can be widely used in some applications like construction, metallurgy, petrochemical industry, boilers, textiles, fans and so on.
