PROCESS FOR THE MANUFACTURE OF VEGETABLE-FIBRE BASED BOARDS, IN PARTICULAR PARTICLE BOARDS OR FIBRE BOARDS

摘要

Manufacture of compounds of particle board, but the other dry processes known panel production from vegetable fibers such as bagasse, are not excluded, provided that the formaldehyde is one component of the glue used. The invention is based on the use of modified starch added to the main adhesive. The modified starch can be a carbamate, ester or ether. These modification products react with residual formaldehyde present in the panel after the capture of the main adhesive thereby greatly reducing the residual formaldehyde emission.
