    摘要： The invention relates to organic fiber-based products and a method of manufacturing such products. According to the method, the fibrous raw material is milled together with a fire-retardant agent to a desired degree of defibering to the end of producing an at least essentially fire-retardant product. According to the invention, the fibrous raw material is admixed with at least a portion of the amount of the fire-retardant agent to be used, after which the material is milled to a desired degree of defibering using a refiner capable of exerting a milling action. Accordingly, when making a product suited for use as thermal insulation, 1/4 - 1/2 of the fire-retardant material is introduced to the fibrous base material prior to defibering in anhydrous form and 1/2 - 3/4 of the fire-retardant material is introduced to the fibrous base material after defibering in hydrous form. According to the invention, recycled paper can be used in the production of an at least essentially fire-retardant organic fiber-based material in which the anhydrous component incorporated therein swells during moisturizing, binds the fibers to each other and thus achieves a structure free from self-compressive settling.

    摘要： A natural fibre-based thermal insulator and a method of manufacturing it. The purpose of the insulator is to thermally insulate buildings and it comprises fibre material which contains organic fibres and synthetic binding fibres, and boron-bearing flame retardants and mould retardants. According to the present invention, the average length of the binding fibres is approximately 30-50 mm, and the fibres which are added into the composition are curved or curly, in which case one binding fibre is capable of binding numerous wood fibres into one binding fibre chain. Sufficient alkali earth metal carbonate is added into the composition to render its percentage of the total weight of the composition approximately 0.1-5.0 %. The carbonate buffers the pH value of the insulator, which makes it possible to use the fibre insulator together with components comprising iron metals, without a risk of corrosion.

    摘要： The present invention relates to a thermal insulation product manufactured from plant-based fibre material, the density of which is 20-120 kg/m 3 , and the fibre material of which is impregnated with an impregnation solution which contains a mixture of fire retardant and anti-mould agent dissolved in a solvent composition which is formed of a poorly evaporating solvent containing OH groups, which solvent is capable of preventing the crystallization of the fire retardants and anti-mould agents and allows them to diffuse into the fibres and chips of the fibre material for a long time, or of a mixture of several such solvents. The invention also relates to a process for manufacturing such a product, wherein the impregnation is carried out using at least a slight overpressure.
