不同处理方法对尾巨桉表面视觉性质及防腐性能的影响
Effect of Different Treatments on the Visual Properties and Decay Resistance Performance of Eucalyptus urophylla × E.grandis
摘要
Abstract
This paper selected tung oil and sodium silicate soaking or coating treatment of Eucalyptus uro-phyllax × E.grandis,and analyzed the surface color difference and decay resistance of the samples before and after treatment.The results showed that after soaking or coating,the lightness(L*),red-green color index(a*)and yellow-blue color index(b*)decreased.Sodium silicate had greater influence on the color of E.urophyllax × E.grandis than tung oil,the ΔE of E.urophyllax × E.grandis impregnated with sodium silicate was the highest,while the color difference of sodium silicate impregnated was greater than that of sodium silicate coating,the ef-fect of tung oil coating was greater than that of impregnated.After soaking or coating,the quality loss rate of E.urophyllax × E.grandis samples infected by Poria vaporaria decreased obviously.The rot resistance of Euca-lyptus urophyllax × E.grandis coated with tung oil,impregnated or coated with sodium silicate reached grade Ⅱ,and that of E.urophyllax × E.grandis impregnated with tung oil reached grade Ⅰ.Impregnation treatment in-creased the content of tung oil and enhanced the corrosion resistance.The corrosion resistance of E.urophyllax × E.grandis,tung oil is better than sodium silicate,impregnation treatment is better than coating treatment.关键词
