DescriptionThe effects of two curing methods- high-frequency heating and hot-platen heating- on the properties of a ure-formaldehyd-bonded medium-density fiberboard prepared with a southern-hardwoods furnish (50% southern red oak, 25% mockernut hickory, and 25% sweetgum) were studied. Boards of three densities- 38, 44, and 50 lb./ft.3- were cured by the two heating methods. IB strength of the high-frequency-cured boards was greater than that of the hot-platen-cured boards at all density levels. Bending properties of the high-frequency-cured boards exceeded those of the hot-platen-cured boards at the highest density level, only. There were no significant differences attributable to the two curing methods in tension parallel to the surface, linear expansion, and thickness swelling.
