我省纤维板生产以云南松原料为主。普遍存在产品质量差,等级率低的问题。多年来始终突破不了一等品率为零的落后局面,二等品率平均只达20％左右,三等品平均为80％,合格率平均不到90％。造成产品质量低的主要原因是云南松原料含有大量的松脂,加之针对性的工艺措施不力,主要表现在产品强度低,吸水率高,碳化粘板,水 Fiberboard production in Yunnan Province mainly to Yunnan pine raw materials. The prevalence of poor product quality, low level of the problem. Over the years has always exceeded the first-class product rate of zero backwardness, second-class products rate average only about 20%, third-class products average 80%, the average passing rate of less than 90%. The main reason for the low quality of the products is that the raw materials of Pinus yunnanensis contain a large amount of rosin and the poor technical measures, which are mainly manifested in the low product strength, high water absorption, carbonized board, water
