えられる。Table 2 From this test result, regardless of the temperature conditions, the filler material of the example has a comparative amount A that does not contain glass fibers with a fiber diameter of 2μ7n or less, and a glass fiber with a fiber diameter exceeding 2μ7n. It can be seen that the tensile strength and mechanical strength are superior when compared to either of the comparison amounts B, which does not contain fibers, and the tensile strength of the comparison amounts △ and B increases rapidly as the acceleration temperature increases. In contrast, there was no such change in the filler material of the actual flow example, confirming that the filler material of this example has excellent heat resistance. This is thought to be due to the fact that the 6 μm glass fiber as the glass JMIt exceeding 2 μm prevents the strength from decreasing during heating.

得られた。In addition, a spiral wound gasket with a predetermined inner diameter and a predetermined outer diameter was manufactured using the filler material of the above-mentioned example, and a spiral gasket with the same dimensions was manufactured using the same hoop material and the filler material of the comparative amount A and 8 described above. When a spiral gasket was manufactured and a comparative test was conducted on the amount of fluid leakage after vibration, the results shown in Table 3 were obtained.

。This performance test was conducted using a 50-ton universal testing machine with a clamping pressure of 200 Kgf/ci, using N2 gas at a rate of 0.5 to 3/ci as a sealing fluid, and measuring leakage m.
A measuring cylinder was used as the measuring device. In addition, in order to change the temperature conditions, the amount of leakage was measured using each spiral gasket at room temperature at the time of initial tightening and each spiral gasket immediately after heating to 600° C. for 3 hours. Furthermore, the vibration frequency is 66.7112. Leakage was measured using each spiral-wound gasket immediately after being subjected to vibration acceleration of 110°7 m/s2 for a total of 4 hours.

が確ルΣされた。Table 3 From this test result, the amount of leakage in the spiral gasket using comparative amount A of filler material increased rapidly due to vibration, and the spiral gasket using comparative amount B of filler material showed a rapid increase in the amount of leakage due to vibration. The leakage ω increases rapidly in response to vibration16, but the spiral-wound gasket using the filler material of the example does not exhibit a sharp increase in the leakage a in both medium and high temperature heating and imaging. It was confirmed that it has an excellent effect on vibration.
