WOOD FIBER INSULATING MATERIALS WITH REDUCED EMISSION OF VOLATILE ORGANIC COMPOUNDS (VOCS) AND METHOD FOR THEIR PREPARATION

摘要

the present invention relates to a method for the production of holzfaserdu00e4mmstoffmatten, especially holzfaserdu00e4mmstoffmatten with reduced emission of volatile organic compounds (vocs), complete the steps: a) preparation of holzhackschnitzeln (or holzstrands) gee igneten wood,(b) torrefizieren of at least part of the holzhackschnitzel; (c) faseraufschluss the untreated holzhackschnitzel and at least part of the torrefizierten holzhackschnitzel to wood; (d) mixing the torrefizierten wood fibers or a mixture of untreated and torrefizierte a wood with at least one binder; (e) application of a mixture of wood and bindemititle to a conveyor belt in a faserkuchens training; and (f) heating and compacting of the faserkuchens to holzfasermatte. the invention concerns also a holzfaserdu00e4mmstoffmatte can be produced by this process and the use of torrefizierten wood to reduce the emission of vocs from holzfaserdu00e4mmstoffmatten.
