標準型橫臥式熱膨脹分析儀 / Standard, Single Sample, Horizontal Dilatometers
Thermal Dilatometric Analysis (TDA), often called "dilatometry", measures the dimensional change of a material (ceramics, glasses, metals, composites, carbon/graphite, minerals, polymers, and others) as a function of temperature. This test determines both reversible and irreversible changes in length (expansion and shrinkage) during heating and cooling, and pinpoints where reactions occur that cause expansion or contraction. Samples are quickly and easily measured for determining firing ranges and firing schedules, measuring thermal expansion ranges for glaze fits, and measuring thermal expansion ranges for R&D, QC or product certification. Orton dilatometers are used for ASTM E-228 testing.
A. Characteristics or Properties Measured
Coefficient of Thermal Expansion (CTE), softening point, glass transition temperature, curie point, crystalline transformation, phase transition, shrinkage, warping, bloating, sintering rate, isothermal creep, stress relaxation.
The test results are a graph of the TDA signal (converted to percent length change) on the Y-axis plotted versus the sample temperature in °C on the X-axis. Sample graphs of enhanced output are shown below.

Computer AnalysisEvery Orton dilatometer is supplied with the software to add to the user's PC in order to acquire, save and analyze the data generated by the dilatometer. The Orton Dilatometer Software is a Visual Basic executable routine written for Windows 95/98/2000/XP English language based personal computers. It can be used to monitor the dilatometer test in real time, or can be used to examine the test data after the run. The software imports the data through the RS232 interface, and stores it on the hard drive for immediate or post-testing analysis. The software enables the user to: View the dilatometer data in a variety of presentations:• Percent linear change (PLC) vs. temperature Perform a variety of analyses:• Calculate the coefficient of thermal expansion (CTE) between specified temperatures, or a series of specified |

| Vertical Dilatometer For larger samples, such as structural clay bodies, a vertical dilatometer is used. The sample is placed into the furnace and the vertical probe rod is lowered to contact the sample (as shown in the photo at the right). The furnace is heated according to the pre-programmed thermal cycle. As the sample temperature changes, the sample expands, pushing up on the probe rod, or shrinks, pulling away from the probe rod. The probe rod is vertically suspended and counterweighted so that gravity keeps it in constant contact with the sample. The probe rod transmits the amount of sample movement to the electronic displacement sensor located overhead and outside the furnace. Orton also designs and manufactures other types of dilatometers, including vertical, multiple sample, metallurgical, quenching, laser, and special application systems. |
