WebThe higher the chlorine content, the higher the heat distortion temperature and tensile strength and the lower the elongation at break and impact strength. Je höher der Chlorgehalt ist, desto höher sind die Wärmeformbeständigkeit sowie die Zugfestigkeit und desto niedriger sind die Bruchdehnung und die Schlagzähigkeit. WebBesides, to compare the distortion of the temperature field quantitatively, we calculate the relative temperature difference Δ between the compared temperature field T i and the reference one T ref, which is formulated as (16) Δ = ∑ Ω B (T i − T r e f) 2 ∑ Ω B (T b a r e − T r e f) 2 When T i = T ref, Δ = 0 % and when T i = T bare, Δ = 100 %.
