软化点试验

的 softening point of asphalt is defined as the temperature at which two disks of a sample can no longer support the weight of a steel ball. As asphalt does not have a specific melting point, the rate at which it softens is extremely important. Because the softening point is needed to establish the uniformity of shipments or sources of supply, it is frequently used to classifying bitumens.

One of the most common ways to determine an asphalt’s softening point is through the use of a ring-and-ball apparatus. During this test, steel balls are placed on top of bitumen disks within a bath. As the temperature of the bath rises, the samples soften and are unable to hold the balls. 的 temperature at which the balls drop 25mm (1 inch) is then recorded.

洪堡 provides a variety of equipment to determine the softening point of bitumen. 的se include a variety of softening point apparatuses as well as a digital option.

的 软化点 Apparatus comes in a double and quad configuration options for desired testing needs. 的se apparatuses do require the purchase of a separate thermometer.
的 软化点 Apparatus Set with Burner can be used for single bitumen determinations. 的 bath is heated by an attached gas burner.
的 软化点 Apparatus Set with Hotplate can be used for single bitumen determinations. 的 bath is heated by an attached hotplate.
的 数字 Auto Ring and Ball Apparatus automatically determine the softening points of bitumen with speed and accuracy. With laser sensors and touch-screen graphics, this machine is easy to use and allows for the management and analysis of data, 测试结果, 和图表.
