磷肥(过磷酸钙)的生产多以含氟磷灰石[3Ca(PO_4)_2·CaF]为主要原料,在生产过程中可产生氟化氢和含氟粉尘,危害工人健康。为了保障工人健康,促进工农业生产的发展,我们对磷肥生产环境的氟化氢和工人尿氟含量,以及工人健康状况作了调查,并提出了改善劳动条件的建议。一、作业环境的氟化氢浓度串联两支扎氏吸收管,内装吸收液,以0.5～1.0升/分的速度采集15升气体。于7月和12月对磷肥车间化成和出料口作业点氟化氢浓度测定的结果,氟化氢浓度均
The production of phosphate fertilizer (superphosphate) is mainly composed of fluorapatite [3Ca (PO 4) 2 CaF], which can produce hydrogen fluoride and fluorine-containing dust in the production process and endanger the health of workers. In order to protect the health of workers and promote the development of industrial and agricultural production, we investigated the fluoride content of hydrogen fluoride and worker’s fluoride in the production environment of phosphate fertilizer and the health status of workers and put forward suggestions on improving working conditions. First, the hydrogen fluoride concentration of the operating environment in series two Zabes absorption tube, containing absorbing liquid to 0.5 to 1.0 liters / min speed of 15 liters of gas collection. In July and December on the phosphate fertilizer plant into the work site and the results of hydrogen fluoride concentration test results, the concentration of hydrogen fluoride
