钛是一种不活泼的元素(Ti)。也是一种难熔的稀有金属,比重4.5、熔点3530℃。自十七世纪九十年代发现以来,由于生产工艺的不断提高,加之钛的优良性能,现已广泛的用于航天,航空工业以及化工石油等工业。从国内外文献上尚未见到有关钛作业工人可引起肺部疾患的报导。从我所三年来对钛作业工人的检查中,我们发现该作业工人中有不同程度的肺部X线改变。现将我们检查该作业工人224例和已确认为钛作业工人尘肺8例分析报导如下;
Titanium is an inactive element (Ti). It is also a refractory rare metal, the proportion of 4.5, the melting point of 3530 ℃. Since the discovery in the 15th century, due to the continuous improvement of production technology and the excellent performance of titanium, it has been widely used in aerospace, aviation industry and chemical industry. There is no report on domestic and foreign literature that titanium workers can cause lung diseases. From my inspection of titanium workers in three years, we found that there was varying degrees of pulmonary X-ray changes among the workers. Now we check the 224 cases of workers and workers have been identified as pneumoconiosis pneumoconiosis 8 cases reported as follows;
