本文报道了石墨尘肺的调查结果。不同工种的粉尘浓度为10.21～87.97mg/m~3,分散度<5μm者占80～90%。五种鳞片石墨产品中游离SiO_2含量为0～3%。对384名接触鳞片石墨粉尘工人进行了体检,石墨尘肺患病率为7.29%,发病工龄平均为20.30年,由Ⅰ期进展到Ⅱ期平均为7.95年,石墨尘肺患者肺功能受到了不同程度的损伤,X线胸片表现以类圆形小阴影“p”改变为主。
This article reports the findings of graphite pneumoconiosis. Different types of dust concentration of 10.21 ~ 87.97mg / m ~ 3, dispersion of <5μm accounted for 80 to 90%. Five kinds of flake graphite products free SiO2 content of 0 to 3%. The examination of 384 workers exposed to graphite flake dust showed that the prevalence of graphite pneumoconiosis was 7.29% and the average length of service was 20.3 years. The average progression from stage Ⅰ to stage Ⅱ was 7.95 years. Pulmonary function in patients with graphite pneumoconiosis was affected to varying degrees Injury, X-ray showed a small round-shaped shadow “p” change-based.
