The recommended filter replacement period is 10–14 months based on formula (G.4). Service life is an estimate and is provided as a reference for replacement cycles only.*CCM of PM 3 times greater than P4: According to "Air Purifiers" (GB/T 18801-2015), a Cumulative Clean Mass (CCM)...
2. Advection can be decomposed along the directions of the connected nodes based on the differential formula and the conservation of mass. We obtain the total convolutional operation to simulate the pollutant traffic on the graph space (Supplementary Fig. 1d): $$\frac{\partial C}{\partial t}...
where VM is volatile matter (%); \({m}_{\mathrm{i}}\) is the initial mass of SD, not oven-dried (g); \({m}_{\mathrm{dry}}\) is the mass of SD, oven-dried (g); and \({m}_{\mathrm{furn}}\) is the mass of SD after treatment in a muffle furnace (g). The ash ...
The properties of PMIA precursor solutions were systematically tested by the methods mentioned in our previous study17,18; however, the charge to mass ratio (e/m) of the charged fluid (jets and/or droplets) during ESN was measured by the typical “mesh target” method using a digital multi...
(EO-rich) polyols having a combined number average equivalent weight from 200 to 800 and an ethylene oxide content from 40% to 65% by weight of the total mass of the EO-rich polyol comprising from 45 to 95% by weight of the isocyanate reactive component; and at least one of one or ...
