Influence of the Hot-pressing Process on the Durability of Totora (Schoenoplectus Californicus C.A. Mey. Soják) Binderless Boards against Wood-decaying Organisms

ABSTRACT

Totora (Schoenoplectus californicus C.A. Mey. Soják) is a macrophyte from the Cyperaceae family that grows in the Americas. Recent studies have shown the feasibility of producing binderless boards using different tissues of totora stems. However, no data about the durability of raw totora stems or totora binderless boards have been published before. Therefore, durability tests were conducted to study their durability against wood-decaying organisms. Results showed that binderless boards produced by hot-pressing process showed higher resistance against white-rot fungi and termites than the raw material. Chemical changes induced by the hot-pressing process were studied and compared with observed durability values to identify possible correlations.

摘要

托托拉（Schoenoplectus californicus C.A. Mey. Soják） 是生长在美洲的 Cyperaceae 家族的巨种植物. 最近的研究表明，使用不同的托拉茎组织生产无粘结板是可行的. 然而，以前没有关于生托拉茎或无粘结板耐久性的数据. 因此，进行了耐久性测试，以研究其耐久性对木材腐烂生物体的影响. 结果表明，热压工艺产生的无粘结板对白萝卜真菌和白蚁的抗性高于原料. 研究了热压过程引起的化学变化，并与观察到的耐久性值进行了比较，以确定可能的关联性.
