The surface potential of the untreated filter webs from respirators A and B ranged from −1.6 kV to +4.4 kV, and these surface charges contributed to particle capture either by coulombic attraction or induced polarization . When the electret media was exposed to IPA, EtOH, and detergent solution, the range of surface potential was considerably ...

At 700 °C (see Figure 3c1–c3), the first transition from rough surface toward smooth surface is observed, and from the temperature of 800 °C, a glassy surface appears (see Figure 3d1–d3). As can be seen, the number of pores visible on the surface decreased with the increase in temperature. The molten and glassy surface has filled the pores.

a Temperature projections are shown for the 2020s (2010–2039), 2050s (2040–2069), 2080s (2070–2099), and 2100. b Different sets of weather stations were used for NPCC 2010 and NPCC 2015, resulting in slightly difference baseline values. N ote: No new average annual temperature projections were developed by NPCC (2019).

The calcining-grinding method can effectively separate the recycled aggregate and attached old cement mortar. The calcination temperature below 100 °C had no great influence on the aggregate. When the temperature was 400 °C, the microhardness decreased to 245 MPa, and the hardness loss rate was 14.6%. The hardness of the aggregate had been ...

14.5.1 Wet bulb temperature, dry bulb temperature and cooling effectiveness. Wet bulb temperature is the lowest temperature to which air can be cooled by the evaporation of water into the air at a constant pressure. It is therefore measured by wrapping a wet wick around the bulb of a thermometer and the measured temperature corresponds to the ...
