沉积称重与粒子计数器结合测定高效净化器的过滤效率
HEPA Filter Test with the Condensation Particle Counter and Mass Measurement (In Chinese)
【摘要】 利用TSI气溶胶发生和检测系统,以微米级超细粉末Sb2O3作为高浓度气溶胶的发生源,采用沉积称重和凝聚核计数器测量相结合的方法,测定了高效过滤器的计重过滤效率,得到过滤器的去污因子DF≥1012。
【Abstract】 The authors use methods of mass measurement and the condensation particle counter to test the high efficiency particulate air (HEPA) filter. The data indicate that the stainless steel HEPA filter fits the requirement of high concentration and radioactive particle filtration, and the study also provides a good method for the HEPA filter test.
