摘要
With the urgent shortage of forest resource in China, using agro-residues as raw materials of composite become increasingly important. Agro-residue is the most potential fiber resource, which is helpful to sustainable development of composite industries in China. Based on a great deal of researches, this paper summarized and discussed some problems in using agro-residues as raw materials of composites, including raw material preparation, hot-pressing, bonding technology, preventing composite from going moldy. It is proposed that to manufacture the composite of rice straws or wheat straws, the isocayante resin is a suitable adhesive, and the appropriate technologies, bonding, and treatment measures are also needed.
在我国森林资源缺乏的形势下,利用农业剩余物制造人造板更加必要,农业剩余物是最具潜力的替代纤维资源。本文基于作者大量的研究经历,总结和讨论了在利用异氰酸酯和农业剩余物制造人造板时,应重视的一些主要问题,包括原料准备、热压工艺、胶接技术、防止霉变等问题,以及相应的解决办法。研究认为,利用稻秸和麦秸制造人造板,最合适的胶粘剂是异氰酸酯树脂胶,同时还应选择合适的工艺、胶接办法和处理办法。表1参9。
