吴登春、刘祥瑜(抚顺市机械局医院)报道;粉尘分散度的测定是判定粉尘危险度的指标之一,目前使用的滤膜溶解法不仅使用有机溶剂量大,吸溶解尘液的吸管清洗也较麻烦,测定选样于溶解混合之后,必须充分混合,快速选样,稍不熟练,就会影响测定结果。现在采用改良方法,即测定选样于样品溶解之前。 其方法:将采样后的滤膜叠成两对折,用剪
Wu Dengchun, Liu Xiangyu (Fushun City Bureau of Machinery Hospital) reported; Determination of dust dispersion is to determine the risk of dust one of the indicators, the current use of membrane dissolution method not only use a large amount of organic solvent, Trouble, the determination of the sample in the dissolution of mixed, must be fully mixed, rapid sample selection, a little unskilled, it will affect the measurement results. An improved method is now used to determine the sample before the sample is dissolved. The method: the sample after the filter folded into two pairs, with scissors
