粘结剂种类和用量对粉煤灰纤维板性能的影响

Effects of Types and Dosages of Adhesive on the Properties of Fly Ash Fiber Boards

以粉煤灰纤维为基材,分别采用水玻璃、聚乙烯醇、水玻璃/聚乙烯醇混合胶为粘结剂,通过水相分散稀释上胶再网滤定型的方法制备粉煤灰纤维板,探讨了粉煤灰纤维用量、粘结剂种类和用量等对粉煤灰纤维板力学性能和吸湿率的影响。

Fly ash fiber boards were prepared by a wet process using fly ash fibers as substrate and water glass, polyvinyl alcohol and the combination of water glass and polyvinyl alcohol as adhesive respectively. Some key factors influencing on the mechanical properties and moisture ratio of fly ash fiber boards, such as the dosages of fly ash fibers and the types and dosages of adhesives were investigated comprehensively.
