摘要

由于高温后的保存可能会导致木材性能的许多不同的,有时是相反的变化,本文的目的是用x射线光谱仪确定含铜防腐剂在白蜡木中的保留和可能的分布。采用最终保留量2和4 kg/m3对应的两种溶液作为防腐剂,进行模型实验室规模的灰分木低压保存。在保存前,除对照样品外,样品在180°C下热处理2或6小时。采用x射线谱仪作图选项,对半切截面表面进行了分析。铜被认为是保留指标。根据得到的结果,可以假设热处理提高了所用参数下样品的可加工性。较长的处理时间增加了制剂溶液的吸收。

An evaluation of the influence of heat treatment on the preservative retention in ash wood (Fraxinus excelsior L.)
As high temperature followed by preservation may cause many different, sometimes contrary changes in wood properties, the aim of this paper was to determine the retention and possible distribution of copper containing preservative in ash wood with an X-ray spectrometer. Two solutions corresponding to the final retention 2 and 4 kg/m3 were applied as preservative for model laboratory scale low-pressure preservation of ash wood. Before preservation was made, samples were heat treated for 2 or 6 hours at 180°C, apart from the control samples. The mapping option of the X-ray spectrometer was applied and the surface on the half-cut cross-section was analysed. Copper was acknowledged as the retention indicator. On the basis of the results obtained, it can be assumed that the heat treatment improves the treatability of samples with the parameters used. Longer treatment durations increase the uptake of the preparation solutions.

期刊介绍: Wood. Research papers. Reports. Announcements" ("Drewno") is an international scientific journal that publishes original results of innovatory basic and applied research concerning technological, technical, economic and ecological issues important for the wood science and forest-based industries, including their environment, and interesting to the international recipients. "Drewno" is an Open Access biannual journal. Aims and scope: wood science: anatomy, biology, chemistry, physics wood mechanical and chemical technology, inter alia, sawmilling, composite wood products, wooden construction, furniture making, wood pulp, paper making material engineering, biocomposites, nanocomposites material management environmental protection, safety of the processes, products and working stations biotechnology bioenergy, biofuels forestry: harvesting and wood quality wood-based industries economics The Editorial Board of the journal especially welcomes articles concerning increase in wood resources (wood mobilisation); innovative composites and lignocellulosic materials; new trends in the protection, modification and finishing of wood; biorefining of raw wood material; "green" building; new technologies of wood waste recycling; sustainable development; innovation management; and business networks.
