Experimental study of nanoparticles penetration through commercial filter mediat face velocities in order to define nanoparticle filtration characteristics of commercial fibrous filter media. The silver particles were generated by heating a pure silver powder source via an electric furnace with a temperature of 870°C, which was found to be the optimal temperature for generatin抵制 发表于 2025-3-23 15:42:50
Reduction of nanoparticle exposure to welding aerosols by modification of the ventilation system in ations underway. The measurements were used to illustrate the impact of change of ventilation methods (existing — with ventilation ducts located at the top, modified — with ventilation ducts located below the weld bench) on the aerosol size distributions at different locations: close to the weld, in培养 发表于 2025-3-23 18:19:05
