3 Terms and Definitions
GB/T 9530-1988 and defined the following terms and definitions apply to this document.
3.1
Linear expansion coefficient coefficientoflinearexpansion
In a certain temperature range, temperature variation changes the value of the sample relative 1K linear dimensions. Common formula (1).
α =
lt-l0
l0 (t-t0)
(1)
Where.
--- coefficient of linear expansion [alpha];
--- initial length L0, the temperature of the unit t0 sample millimeters (mm);
Length in lt t --- the heating temperature when the sample was to millimeters (mm).
Test Method 4
4.1 Samples should be consistent with GB/T 5593-2015 requirements in Table 2 and with an accuracy of 0.02mm caliper measurement sample length L0.
4.2 sample was placed on Al2O3 ceramic or quartz glass tube, it should be kept straight and steady, and high temperature and quartz glass or ceramic Al2O3
Porcelain transmission lever contact. With 10 times the magnifying glass, there should be no visible cracks and pores.
4.3 power, heating and uniform heating. A sample rate of temperature increase of not more than 5 ℃/min.
4.4 points record temperature and elongation values \u200b\u200bΔL, until the desired temperature is reached to test (measuring range from room temperature to 1200 ℃).
4.5 according to the different types of instrument, test results can be displayed directly on the computer screen, or by the formula (2) to calculate the value of α.
α =
ΔL
M × L0 × ΔT
α medium (2)
