摘要
从各种不同渠道详细调查了1995年至2002年中国脂松香的质量状况。对调查结果进行了统计分析,并将调查结果与脂松香国家标准(GB/T8145-1987)的各项主要技术指标进行了相应的对比研究。结果表明,单就技术指标的统计平均结果而言,各个级别的脂松香质量均优于目前的国家标准要求,而且仍然具有国际领先水平。但是,"混合松香"等质量问题必须引起各方面的足够重视。根据中国采脂树种和客户实际需求的不断变化,按照不同树种或不同用途分别制定分类松香标准或专用松香标准将是未来质量要求的发展趋势。
State on quality of Chinese gum rosin from 1995 through 2002 was investigated in detail.Data were statistically analyzed and compared with the main technical specifications required in GB/T 8145-1987.Statistical average results showed that the present state on quality of Chinese gum rosin is superior to the specification required in GB/T 8145-1987 and is still ranking international top level,if only experimental values were considered.However,quality problems such as socalled 'mixed rosin' should be seriously paid attention to.According to the increasing tapping pine species and various uses of gum rosin,adoptation at different standards of gum rosins for individual pine species or individual uses would be the trend to meet the quality requirements in the future.
