Application of an aqueous dispersion of zinc borate in the preservation of wood composite products

摘要

The resistant biological degradation of composite wood products is improved by applying a suitable aqueous dispersion of zinc borate onto the fibres to uniformly distribute and to adhere the zinc borate to the strands of the wood composite, applying a suitable adhesive to the wood strands, forming a strand lay-up and consolidating a lay-up under heat and pressure to form a consolidated product with zinc borate uniformly distributed there through.
