Definitions
- the rate of lime, CaO, of the selected compositions is between at least 16 and 25%.
- the CaO lime level is preferably greater than 16.5 %, in particular greater than 17% and / or preferably less than 23%, in particular less than 20%.
- composition has made it possible to combine a whole series of advantages, in particular by playing on the multiple, complex roles played by a certain number of its specific constituents.
- biosoluble character it is known to increase the alumina content of mineral wool compositions in order to obtain good biosolubility when the alumina level is around 20%.
- compositions result in significant additional costs, in particular because of the raw materials carrying alumina, the cost of which is high, for example bauxite. It is therefore particularly advantageous to limit the level of alumina.
- compositions according to the invention are both compatible with fiberizing processes and particularly biosoluble with moderate levels of alumina, which we will hereinafter call “intermediate alumina”.
- Adding boron oxide which is optional and in particular of a content of 1 to 5%, preferably at least 2% and / or preferably at most 4%, can make it possible to improve the thermal insulation properties mineral wool, in particular by tending to lower its coefficient of thermal conductivity in its radiative component.
- the composition can also contain TiO 2 as impurities or added voluntarily, for example in a content up to 1 to
- the mineral wools according to the invention are used mainly for manufacturing thermal and / or acoustic insulation products or soilless growing substrates.
- the subject of the invention is also all products comprising at least in part mineral wools defined above. Other details and advantageous characteristics will emerge from the description below of preferred nonlimiting embodiments.
