What is the difference between rock wool and glass wool?
Rock wool and glass wool are two common insulation materials widely used in fields such as construction and industrial equipment. Although they all have excellent insulation, sound insulation, and fire resistance properties, there are significant differences in raw materials, production processes, and performance characteristics.
1. Different raw materials
Rock wool: Natural rocks such as basalt and diabase are used as the main raw materials, which are melted at high temperatures and then made into fibers through centrifugal technology.
-Glass wool: mainly made of glass materials such as quartz sand, limestone, borax, etc., melted at high temperature to make fibers.
2. Different production processes
Rock wool: Using high-temperature melting (about 1500 ℃) and centrifugal fiber forming process, the fibers are thicker and the structure is more compact.
Glass wool: Using high-temperature melting (about 1000 ℃) and spray blowing to form fibers, the fibers are finer and the texture is softer.
3. Performance Characteristics Comparison
(1) Thermal insulation performance
Rock wool: Low thermal conductivity, excellent insulation performance, suitable for high temperature environments.
Glass wool: Its thermal conductivity is slightly higher than that of rock wool, but it also has excellent insulation effect at room temperature.
(2) Sound insulation performance
Rock wool: The fiber structure is compact and has good sound insulation effect, especially suitable for low-frequency noise environments.
Glass wool: With delicate fibers and excellent sound absorption performance, it is suitable for medium to high frequency noise environments.
(3) Rock wool: with a fire rating of A1 and a high temperature resistance of over 1000 ℃, it has excellent fire resistance.
Glass wool: with a fire rating of A, it can withstand high temperatures of about 500 ℃ and has good fire resistance.
(4) Compressive strength
Rock wool: The fibers are relatively coarse, with high compressive strength, suitable for load-bearing environments.
Glass wool: with fine fibers and low compressive strength, suitable for non load bearing environments.
4. Application scenarios
Rock wool: commonly used for building exterior wall insulation, industrial equipment insulation, fire isolation belts, etc.
Glass wool: commonly used for building interior wall insulation, pipeline insulation, air conditioning system sound insulation, etc.
