Title: Chipboard prodn. using wood or plant resin binder - opt. with formaldehyde, and cooling press before opening
Inventor: CLAD WERNER DIPL ING DR
IPC: C08L97/02
Filed: 1977-07-21
Abstract: Natural resins of wood chips and comminuted plants, opt. together with HCHO, are used as binders in chipboards and other plant-derived pressed article prodn. On using the plant resins alone, pressing is affected with heating and re-cooling before opening the press tools. No re-cooling is needed when adding HCHO.
