The purpose of this review is to put previous research findings on acetylated wood and the fabrication of veneer-based products in a common context. The first research on wood acetylation was already conducted in the 1920s using wood meal, whereas relevant research on veneer acetylation was published nearly two decades later, during the 1940s. In the years that followed, a great deal of research has been done on both solid wood and composite acetylation. Developments in the 1990s and early 2000s resulted in the creation of commercial products. Nowadays, wood is becoming increasingly popular in construction. Therefore, high-performance materials with high dimensional stability and durability are required. Veneers are thereby of particular relevance because of their propensity to absorb chemicals into even tough-to-treat wood species. However, acetylation alters the bonding properties of wood, which is important for the manufacture of engineered veneer products, especially in load-bearing construction. A large amount of research is now being conducted on the acetylation of veneer, and acetylated veneer products are anticipated in the near future. This study covers the fundamentals of bonding but focuses specifically on veneer acetylation and its fabrication to engineered veneer-based products. The influencing factors of acetylation on bonding are also discussed.
本综述的目的是将以往关于乙酰化木材和单板基产品制造的研究成果置于一个共同的背景下。对木材乙酰化的首次研究早在20世纪20年代就已使用木粉进行，而关于单板乙酰化的相关研究则在近二十年后的20世纪40年代发表。在随后的几年里，对实木和复合材料的乙酰化都进行了大量研究。20世纪90年代和21世纪初的发展促成了商业产品的问世。如今，木材在建筑领域越来越受欢迎。因此，需要具有高尺寸稳定性和耐久性的高性能材料。单板因其能够将化学物质吸收到即使是难以处理的木材品种中而具有特别重要的意义。然而，乙酰化会改变木材的粘结性能，这对于制造工程单板产品至关重要，尤其是在承重建筑中。目前正在对单板的乙酰化进行大量研究，预计在不久的将来会出现乙酰化单板产品。本研究涵盖了粘结的基本原理，但特别关注单板乙酰化及其制造工程单板基产品的过程。还讨论了乙酰化对粘结的影响因素。
