Introduction

Thermal dilatometer is used to measure the expansion and contraction performance of metal materials, ceramics, glass, glaze, refractory materials and other non-metallic materials in the process of hot roasting. The computer automatically calculates the coefficient of expansion, the coefficient of volume expansion, the linear expansion amount, the rapid thermal expansion.

Representive Results

1. samples sintered at 1300 as a function of sintering time: (a) porosity °Cand density and (b) thermal expansion coefficient and flexural strength

Sample Requirement

1. Solid block sample

Along the thickness direction, the length is 6-10mm, the width is 6-10mm, and the thickness is 1-4mmMulti-directional: length 6~10mm, width 6~10mm, thickness 6~10mm.

2. Solid film samples

Single direction: length 20~50mm, width 5~8mm, thickness 20~200um.

Multi-directional: length 20-50mm, width 20-50mm, thickness 20-200um.

3. The sample has no defects, no bubbles, smooth surface, and can be polishedwith more than 400 mesh sandpaper.

4. In the expansion mode test of the polymer sample, the sample needs to be heat-treated at the glass transition temperature +30°C for 1 hour, and then slowly cooled to room temperature.

5. For solid film samples in tensile mode, it is necessary to determine the orientation direction of the film for testing.
