摘要
以硫酰氟和氧硫化碳为熏蒸剂,分别采用不同浓度对美国南方松进行熏蒸处理,研究熏蒸处理对美国南方松材色的影响,并通过红外光谱测试分析发生材色变化的原因。结果表明,无论采用哪种熏蒸剂,熏蒸处理前后,美国南方松的色度学参数明度值L~*、红绿色品指数a~*和黄蓝色品指数b~*没有显著变化。色差值属于有轻微视觉感觉。在达到检疫除虫要求的情况下,氧硫化碳熏蒸剂对美国南方松材色的总体影响更小。
In order to study the influence of fumigation treatment on color, Pinus spp. was treated by different levels of sulfuryl fluoride and carbon oxysulfide as fumigants respectively. FTIR analysis has been done to find possible reasons for color change. The resuh shows that there is not remarkable changes on chroma parameters L＊, a＊,b＊ after fumigation. Color difference belongs to the level of slight visual feeling. In the precondition of reaching the requirement of quarantine, fumigant carbon oxysulfide has less influence on wood color in general.
