一、前言木材天然耐腐抗虫蛀的性能是指木材本身固有的抗性。这种性质随树种不同而异,它与各树种木材的组织结构、木材物理性质以及内含物的化学成分有关。由于木材是这样一种复杂的有机物、它在贮运和使用过程中很容易遭到多种微生物和害虫的侵害,导致木材的败坏,使国民经济各项建设事业受到不必要的损失。所以从木材利用的要求出发,总希望木材具有天然抗生物性能,能经久耐用,在长期使用中能保持足够的强度和原有的性质,但各种木材天然抗性却很不一致,有的不仅耐腐,而且抗虫蛀性能也强,可使用
First, the foreword Wood natural decay resistance Insect resistance refers to the inherent resistance of wood itself. This property varies with tree species and is related to the wood structure of the species, the physical properties of the wood, and the chemical composition of the contents. Because wood is such a complex organism, it is easily subjected to many kinds of microorganisms and pests during storage and use, causing the deterioration of timber and causing unnecessary losses to various construction projects in the national economy. Therefore, from the requirements of the use of wood, always hope that the wood has natural anti-biological properties, can be durable, long-term use to maintain adequate strength and original nature, but a variety of natural wood resistance is very inconsistent, and some not only Corrosion resistance, but also strong anti-moth-eaten, can be used
