摘要炭黑是橡胶中最重要的补强填料，要有效发挥其作用，必须对其进行良好的分散。正如Tidmus和Parkinson所描述的那样，通过使用透射光对橡胶化合物的薄(2微米)部分进行显微镜检查，可以有效地研究炭黑的分散状态。显微镜下可见未分散的炭黑凝聚体。这些凝聚体的大小可能高达100微米，甚至更大，它们被玻璃刀或多或少地干净地切割，在浅棕色的田野中显示为黑色或深棕色的岛屿。虽然这种方法最初是为了定性地估计分散程度，但后来Leigh-Dugmore开发了一种定量计算方法，用来计算分散在一定尺寸以下的炭黑的百分比。这一计算有助于对外观差异很大的股票进行定量比较。随着经验的积累。
Abstract Carbon black, the most important reinforcing filler for rubber, must be well dispersed if it is to function effectively. The state of dispersion of the carbon black can be studied effectively by microscopic examination of a thin (2µ) section of the rubber compound, using transmitted light, as described by Tidmus and Parkinson. Under the microscope, agglomerates of undispersed carbon black are visible. These agglomerates, which may range in size up to 100µ or even larger, are sectioned more or less cleanly by the glass knife, and appear as black or dark brown islands in a light brown field. While this method was originally proposed for qualitative estimation of the degree of dispersion, a quantitative calculation was subsequently developed by Leigh-Dugmore, by means of which the percentage of carbon black dispersed below a certain size was calculated. This calculation has been helpful in permitting a quantitative comparison of stocks of widely different visual appearance. As experience has accumul...
