专利汇可以提供Fiberboard produced from wood particles having a 5 to 25 percent moisture content prior to steaming and mechanical reduction in the formation process专利检索,专利查询,专利分析的服务。并且Fiberboard is produced by subjecting a mass of wood particles that have previously been dries to a moisture content in the range of about 5 to 25 percent to steaming and mechanical reduction to form a mass of lignocellulosic material in fibrous form; mixing the latter with a solution of the essentially unreacted ingredients of a thermosetting resin; compressing the resulting mass to desired thickness between separately heated platens; creating between said platens and throughout said mass a high frequency electric field; and maintaining said field for a time sufficient to initiate and at least partially complete the reaction of said ingredients; said solution of essentially unreacted ingredients of thermosetting resin having a viscosity under about 100 c.p.s. and a resin solids content of at least about 45 percent.,下面是Fiberboard produced from wood particles having a 5 to 25 percent moisture content prior to steaming and mechanical reduction in the formation process专利的具体信息内容。
