摘要： A thermal and/or acoustic insulation product includes a loose mineral wool, the mineral wool including mineral fibers and being suited to being blown. The fibers have a fiber length population distribution such that the ratio of the fiber length equal to the 90th percentile in distribution number to the median fiber length in distribution number is greater than 3, and the product includes at least one additive and has a total additive weight percent of between 0.4% and 1.2% inclusive.

摘要： A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of:



Forming mineral fibres from a molten mineral mixture;
Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen;
Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and
Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.

摘要： The invention relates to the field of materials based on mineral fibers, in particular mineral wool such as glass wool or rock wool. More specifically, the present invention relates to a method and a device for recycling the water recovered in a fiberizing and shaping method when using a specific acid binder based on monomeric polycarboxylic acid, or a salt of such an acid.
