蒸汽机车按照其运行线路供水水质情况,而备有一定量不同浓度之碱溶液,以减低锅炉用水之硬度。大同铁路分局管内机事,都以氢氧化钠加适量烤胶(丹宁酸C_(14)H_(10)O_9)和磷酸钠(NA_3POo_4)作水质软化剂。这碱溶液溅入眼内就要发生灼伤,本院自1962年以来,就大同铁路地区所遇机车乘务员眼部碱灼伤18例报告如后附表致伤原因本组病例均为机车乘务员司机、副司机、司炉三个工种,平均工龄7年,都发给防护眼镜。所在机车均备有碱溶液小桶,桶上有安全
Steam locomotive water quality in accordance with its operation line, and with a certain amount of alkali solution of different concentrations to reduce the hardness of boiler water. Datong Railway Branch tube machine, are sodium hydroxide plus the amount of baking glue (tannic acid C_ (14) H_ (10) O_9) and sodium phosphate (NA_3PO_4) as a water softener.
