Beech Veneer Plasticity Change after Steaming and Ammonia Treatment: Case Study - "Limit" Stool

Popis výsledku v původním jazyce

Steaming and ammonia treatments are used in order to change the color of wood and also to plasticize the wood before bending or compressing. The mechanisms and process of gaseous ammonia treatment alone or in combination with steaming the wood are not very well known. The goal of this study is to quantify the effect of gaseous ammonia or steam on wood densification and bending as well as on mechanical properties i.e., modulus of elasticity (MOE), modulus of rupture (MOR) and deflection at maximal loading force (yFmax). When wood was treated by water and ammonia vapour treatment, significant changes in the plasticity of wood were observed. The samples which were first exposed to water vapour and then to ammonia vapour exhibited the lowest values of MOEand MOR, enhancing the flexibility of the material. The results show that ammonia treatment increases plasticity of wood. This process can be used for the manufacture of bent furniture. The stool "limit" is presented in the second part of
