Table 2 Performance parameters of SHOU DPEA at different aging cycles.

From: Effects of thermal aging on the performance of ordinary and novel superhydrophobic and oleophobic ultra-fine dry powder extinguishing agent

  1. Assuming the interparticle adhesion force (fa) of non-aged SHOU DPEA as 1 (dimensionless), calculate the fa multiples on the 40th, 80th, 120th, 160th, and 200th day compared to non-aged SHOU DPEA.
