    摘要: A method and system for separating a particulate contaminate from a contaminated liquid medium involves filtering the contaminated liquid medium with a filter element having an afflux surface made of plastic particles that are sintered together. The contaminated liquid medium is introduced into a vessel, brought into contact with the filter element, where the liquid medium is separated from the particulate contaminant, and the separated liquid medium withdrawn from the filter element.

    摘要: A process for the production of a wood composite, such as fiberboard, having improved surface characteristics includes the application of an alkali metal salt, e.g. an alkali metal carbonate. The process also reduces the amount and integrity of carbon film that generally forms in the die during consolidation, making the die significantly easier to clean.

    摘要: High strength and high density wood fiberboard is formed by treating the wood fiber source material with a highly alkaline solution, such as sodium hydroxide solution, before interfelting the fibers into a loose mat. The wood source material may be treated after refining the material into fibers, but preferably, the wood source material is treated before fibrillation. Further, wood fiber source material may be partially neutralized before felting without substantial change in the resulting densities and strengths.
