Medium density mixed hardwood flake lamina |
摘要 |
A lamina for a medium density structural board made from dimensioned wood flakes cut from a mixture of hardwood species and having a high retained internal bond strength is disclosed. The wood flakes are blended with a phenol formaldehyde resin having a major quantity of a low molecular weight fraction and a wax and then formed into a hot pressed product. The lamina may be used alone or as the core of a structural board having veneer, hardboard or plywood face panels. Three or more lamina may be formed into a structural board or used as the core of a board having veneer, hardboard or plywood face panels.
