There are differences between rock wool and glass wool in the following five aspects:
1.Ingredients:Rock wool is made of natural rocks such as basalt, gabbro and so on through high-temperature melting processing;Glass wool is made of ground fiberglass.
2.Production mode:Rock wool is processed into fibers by melting at high temperatures, and then processed by adding special binders and dust-proof oils, while glass wool is processed by spraying or pendulum method.
3.Fiber distribution:Rock wool fibers are irregularly distributed, and glass wool fibers are regularly distributed, which is one of the main differences between the two materials.
4.Thermal Insulation Performance:The thermal insulation performance of rock wool is relatively good, but its thermal insulation performance begins to weaken significantly when the temperature reaches more than 800 metersThe thermal insulation performance of glass wool is relatively more stable and has a certain resistance to temperature changes.
5.Environmental friendliness:The melting point of rock wool is about 1000 and cannot be degraded, while glass wool is directly netted by air flow, with no excess residue and is environmentally friendly.
In general, stone wool and glass wool have their own characteristics, and the choice of which material to use needs to be decided according to the specific application and needs. In terms of thermal insulation, noise reduction, fire prevention, etc., rock wool and glass wool have a wide range of applications.
