煤焦瀝青是炼焦时煤焦油的副产品,其化学成份十分复杂,其中主要成分有石炭脑、咔唑、吖啶、菲、蒽、(口匹)啶又引(口孕)等物。这类物質接触到人体的皮肤、粘膜,常引起皮疹和粘膜损害。煤焦瀝青具有高度的沾着性,能固着于木材表面以防腐防潮,如铁路之枕木、电杆、桥梁等均外涂瀝青,借以防腐,并为基建及筑路所必需之原料。在我国进行大规模社会主义建设的今日,瀝青的使用范围十分广泛。为了加强对工人健康的保护和为生产服务,曾至市政建设公司某预制厂进行现埸调查,并对141名瀝青工人作了全面的体格检查,结合临床分析,报告如下: 生产过程
Coal tar pitch is a by-product of coal tar during coking. Its chemical composition is very complicated. The main components are charcoal brain, carbazole, acridine, phenanthrene and anthracene, and oral (oral) pyridine. Such substances come into contact with human skin, mucous membranes, often cause rash and mucosal damage. Coal tar pitch has a high degree of stubbornness, can be fixed to the surface of the wood to prevent moisture, such as railroad sleepers, poles, bridges and so on are coated with asphalt, so as to prevent corrosion, and infrastructure and road building materials. In today’s large-scale socialist construction in our country, the use of asphalt is very extensive. In order to strengthen the protection of workers’ health and service for production, a survey has been carried out to a prefabrication plant of the municipal construction company. A total of 141 asphaltic workers were physically examined. Combined with clinical analysis, the report is as follows: Production Process
