染毒室容积为0.17m~3,蒸气发生加热器用自动控温仪保持恒温。风速0.25~0.5m/sec,相对湿度50~77%。气温一般高出工作室温1~4℃,受蒸发温度与外界气温影响。试测表明:十二烷基苯在常温常压下挥发极微,在室温28±1℃、平均风速0.29m/sec的条件下,平均蒸气量为26.4μg/cm~2·h,基本上解决了低挥发性有机物(液相)经呼吸道动式染毒的实验。
The volume of the poisoning chamber is 0.17m ~ 3, and the steam generator heater is kept at a constant temperature with an automatic temperature controller. Wind speed 0.25 ~ 0.5m / sec, relative humidity 50 ~ 77%. The temperature is generally higher than the working room temperature 1 ~ 4 ℃, affected by the evaporation temperature and outside temperature. The test shows that the average vapor content of dodecylbenzene is 26.4μg / cm ~ 2 · h under the condition of average temperature of 28 ± 1 ℃ and average wind speed of 0.29m / sec under normal temperature and pressure. Basically Solve the low volatile organic compounds (liquid phase) by the respiratory tract dynamic exposure experiments.
