    • Embodiments of a composition useful for forming cellulosic products are disclosed, as well as products made using disclosed compositions. One disclosed composition comprises effective amount of dihydroxyethylene urea(s), dihydroxypropanol ureas, glycoluril(s), or combinations thereof. Such compositions can be cross linked, or not. The compositions can include other materials, such as methylol melamine; maltodextrin, where the DE of the maltodextrin can vary from about 4 to about 25, optional auxiliary additives, including a surfactant; a trialkanolamine, a preservative, a fire retardant; an aesthetic material, such as a dye that, in certain embodiments, substantially completely penetrates the cross section of the board product; a hardness enhancer; and any and all combinations of such materials. One embodiment of a disclosed method for making a cellulosic product comprises first providing a disclosed composition and applying it to cellulosic material, such as by substantially immersing cellulosic material in desired compositions in an autoclave.
    • 公开了用于形成纤维素产品的组合物的实施方式,以及使用公开的组合物制造的产品。 一种公开的组合物包含有效量的二羟基亚乙基脲,二羟基丙醇脲,甘脲或其组合。 这种组合物可以交联或不交联。 该组合物可以包括其他材料,例如羟甲基三聚氰胺; 麦芽糖糊精,其中麦芽糖糊精的DE可以在约4至约25之间变化,任选的辅助添加剂,包括表面活性剂; 三烷醇胺,防腐剂,阻燃剂; 美学材料,例如染料,在某些实施例中,所述染料基本上完全穿透板产品的横截面; 硬度增强剂; 以及这些材料的任何和所有组合。 所公开的用于制造纤维素产品的方法的一个实施方案包括首先提供所公开的组合物并将其应用于纤维素材料,例如通过将纤维素材料基本上浸渍在所需组合物中的高压釜中。

    • A process for providing a hardened wooden product from a source wooden item, said process comprising or including loading a pressure vessel with sapwood items of sufficient dryness, drawing a reduced pressure in the closed pressure vessel, immersing the sapwood in the pressure vessel in an aqueous aminoplast resin impregnating composition ('aqueous formulation"), pressurising the impregnating composition in the treatment vessel, removing excess impregnating composition from the fully impregnated sapwood in the pressure vessel, lowering the pressure in the vessel, opening the pressure vessel, removing the impregnated sapwood from the pressure vessel, subjecting the removed impregnated sapwood to conditions to reduce its moisture content, subjecting the dryer impregnated sapwood to conditions to facilitate curing, subjecting the at least substantially cured impregnated sapwood to conditions to further reduce the moisture content thereof thereby to derive the hardened sapwood product.
    • 一种用于从源木制品提供硬化的木制品的方法,所述方法包括或包括用压力容器加载具有足够干燥度的边材,在封闭的压力容器中减压,将边材浸入压力容器中的水溶液 氨基塑料树脂浸渍组合物(“含水制剂”),对处理容器中的浸渍组合物加压,从压力容器中的完全浸渍的边材中除去过量的浸渍组合物,降低容器中的压力,打开压力容器,除去浸渍的边材 从压力容器中,将去除的浸渍的边材经历以减少其含水量的条件,使干燥器浸渍的边材经受条件以促进固化,使至少基本上固化的浸渍的边材经受进一步降低其含水量的条件,从而得到 硬化边材产品。
