Filling cavities with plastics foam for manu - of fibre agglomerate panels

摘要

At least one component of the foaming reaction is introduced into the cavities in wood-wool, fibres, or granulates, in the form of a closed capsule. This is then burst by a supply or energy from foam and fills the cavities. Specif., the energy is heat, pressure, energy, radiation, electromagnetic radiation, steam, shock or dissolution. Specif., during foaming, a treatment is effected with diisocyanate gas produced or supported by vaporisation of an accelerator.
