摘要： Methods and systems for making a fiberboard product having a desired final thickness dimension by subjecting a fibrous board preform to a successive series of compressive pressures. Preferably, an upstream one of the compressive pressures causes the board preform to exhibit a compressed thickness dimension which is less than the final thickness dimension of the fiberboard product, while a downstream one of the compressive pressures causes the board preform to exhibit a thickness dimension which is substantially the same as the final thickness dimension of the fiberboard product. Between subjecting the board preform to these upstream and downstream compressive pressures, the upstream one of the compressive pressures may be removed sufficiently to cause the compressed thickness dimension to increase to an intermediate thickness dimension which is less than the initial thickness dimension of the board preform, but is greater than the final thickness dimension of the fiberboard product. Most preferably, the upstream compressive pressure is accomplished by passing the board preform between and through a nip space defined between an opposed pair of rolls.
摘要翻译：通过使纤维板预制件经受连续的压缩压力来制造具有所需最终厚度尺寸的纤维板产品的方法和系统。优选地，上游压缩压力之一导致板预制件呈现的压缩厚度尺寸小于纤维板产品的最终厚度尺寸，而下游的一个压缩压力使板坯预制件呈现厚度尺寸，与纤维板产品的最终厚度尺寸基本相同。在板坯预制件经受这些上游和下游压缩压力之间，可以充分去除上游压缩压力以使压缩的厚度尺寸增加到小于板坯预成型件的初始厚度尺寸的中间厚度尺寸，但是大于纤维板产品的最终厚度尺寸。最优选地，上游压缩压力通过将板预制件通过在相对的一对辊之间限定的辊隙空间之间来实现。

摘要： A method and system provide for the production of mineral fiber boards using at least 25 % (preferably at least about 90 %) inorganic fibers having enhanced uniformity, compressive strength, and dimensional stability. The source of fibers may be pre and/or post consumer recycled fiberglass. A liquid slurry of solids, including at least 25 % inorganic fibers having an average length of at least about one-half inch, with a solids consistency of about 0.4-8 % is formed. A pack at least about one inch thick is formed from the slurry using a foraminous element, and water is extracted. The pack is dried, and binder may be added and cured, to produce a product at least about one inch thick. Exhaust gases from the drier may be filtered by passage through the pack prior to drying, while also facilitating dewatering of the pack.
摘要翻译：使用至少25％（优选至少约90％）具有均匀性，抗压强度和尺寸稳定性的无机纤维来生产矿物纤维板的方法和系统。纤维来源可以是消费前和/或后消费的再生玻璃纤维。形成固体的液体浆料，其包含至少25％平均长度为至少约1/2英寸的固体浓度为约0.4-8％的无机纤维。使用多孔元素从浆料形成至少约1英寸厚的包装，并且提取水。将包装干燥，并且可以加入和固化粘合剂，以产生至少约1英寸厚的产品。来自干燥器的废气可以在干燥之前通过包装过滤，同时也有助于包装的脱水。
