• Continuous process for forming a unitary mat

  公开（公告）日：2019-02-12

  A continuous process forms a unitary mat on a line having at least two conveyors spaced from each other. The process includes combining the isocyanate, an isocyanate catalyst, and a plurality of lignocellulosic particles to form a mixture and a self-polymerization product of the isocyanate in-situ in the mixture. The process also includes forming the unitary mat from the mixture on a first conveyer and transferring the unitary mat from the first conveyor to a second conveyor across a predetermined distance while maintaining structural integrity of the unitary mat. The lignocellulosic particles have a moisture content of 0.5 to 30 weight percent of water. Moreover, the continuous process is free of a step of adding water to the isocyanate, the isocyanate catalyst, the lignocellulosic particles, and/or the unitary mat.

  一种连续生产工艺可在一条至少有两个相互间隔的传送带的生产线上形成一个单元垫层。该工艺包括将异氰酸酯、异氰酸酯催化剂和多个木质纤维素颗粒结合在一起，形成混合物和异氰酸酯在混合物中的原位自聚合产物。该工艺还包括在第一传送带上将混合物形成单元毡，并在保持单元毡结构完整性的同时，将单元毡从第一传送带传送到第二传送带，传送距离为预定距离。木质纤维素颗粒的水分含量为 0.5-30 重量百分比。此外，连续工艺中没有向异氰酸酯、异氰酸酯催化剂、木质纤维素颗粒和/或单元毡中加水的步骤。
