标准范围

用于制备用于生产铝的电极的沥青密度是一个特性，它可以指导其质量的一致性。这个参数的知识对于音高的最佳使用至关重要。在真空下脱气后，在25°C下通过比重瓶测量密度进行测定。

The density of pitch used for preparation of electrodes for the production of aluminium is a property which gives a guide to its consistency of quality. Knowledge of this parameter is essential for optimum use of pitch. The determination is carried out by measuring the density in a pyknometer at 25 °C, after degassing under vacuum.
