The present invention concerns a method of producing a moulded mineral wool insulation product, said method comprising the steps of providing a mixture by mixing mineral fibres with a binder composition, and providing said mixture in a mould form, and then curing the binder, wherein the binder composition comprises at least one hydrocolloid, and then removing the moulded product from the mould form.

Method of manufacturing a moulded mineral wool product and a product of such kind

A panel and a method of making a panel are provided. The panel comprises a cured polymeric foam layer that is formed by application of a foam composition to an edge surface of the panel and then shaped and cured. The panel comprises man-made vitreous fibre or wood wool cement.

Panel

Method for manufacturing an aerogel-containing composite, said method comprising the steps of: providing fibers, at least some of which are first fibers, such as mineral fibers, polymer fibers, cellulose fibers, or other types of fibers, in an amount of from 3 to 80 wt % of the total weight of starting materials, providing an aerogel particulate material in an amount of from 10 to 75 wt % of the total weight of starting materials, providing a binder in an amount of from 1 to 30 wt % of the total weight of starting materials, suspending the fibers in a primary air flow and suspending the aerogel particulate material in the primary air flow, thereby mixing the suspended aerogel particulate material with the suspended fibers, mixing the binder with the fibers and/or aerogel particulate material before, during or after mixing of the fibers with the aerogel particulate material, collecting the mixture of fibers, aerogel particulate material and binder and pressing and curing the mixture to provide a consolidated composite with a density of from 120 kg/mto 800 kg/m. With this method homogeneous composites can be produced.

Method for manufacturing an aerogel-containing composite and composite produced by that method

The invention relates to a method for manufacturing an insulating composite containing mineral fibers, aerogel and binder. This method implies the step of suspending the fiber webs and aerosol in an air flow thereby disentangling the fiber webs and mixing fibers, aerosol and eventually binder homogeneously. The apparatus described combines spinning of the fibers, collecting them as webs, disentangling the fiber webs in suspended air, mixing the fibers with aerogel and cement as well as pressing and curing the mixture to a consolidated product of density 150 to 800 kg/m.

A method for manufacturing a fiber-containing element, said method comprising the steps of: providing fibers, at least some of which are first fibers, such as mineral fibers, polymer fibers, cellulose fibers, or other types of fibers, in an amount of from 3 to 98 wt % of the total weight of starting materials in the form of a collected web, providing a binder in an amount of from 1 to 30 wt % of the total weight of starting materials, subjecting the collected web of fibers to a disentanglement process, suspending the fibers in a primary air flow, mixing the binder with the fibers before, during or after the disentanglement process, providing a filler, such as a fire retardant, in an amount of 1 to 55 wt % of the total weight of starting materials, adding the filler at any suitable step of the method, such as before, during or after the disentanglement process, collecting the mixture of fibers, filler and binder and pressing and curing the mixture to provide a consolidated composite with a density of from 120 kg/mto 1000 kg/m. With this method homogeneous composites can be produced.

Method for manufacturing a fibre-containing element and element produced by that method

The invention relates to a method for manufacturing a mineral fiber-containing composite and the novel mineral fiber-containing element produced by that method. The invention also relates to an apparatus suitable for carrying out the method of the invention.
