水泥的主要成分是氧化钙,含量达63.8%,加水后形成强碱性物质(PH11～13的)氢氧化钙.水泥对健康的危害,主要表现在吸入粉尘后的尘肺病和接触水泥浆后的烧伤.水泥尘肺是属于病变较轻的硅酸盐肺,发病进展较慢,多见于从事水泥生产使用工作10年以上者,在初期,病人无特殊不适.最易被忽视,到了中期,可见咳嗽、吐痰、胸闷和一时性胸痛,又容易被误诊为支气管炎;待到
The main component of cement is calcium oxide, content of 63.8%, after the formation of strong alkaline substances (PH11 ~ 13) of calcium hydroxide. The health hazards of cement, mainly in the inhalation of dust pneumoconiosis and after exposure to grout Of the cement .Pneumoconiosis is a lesser lesser silicate lung, the incidence of progress is slower, more common in cement production for more than 10 years of work, in the initial, the patient no special discomfort. The most easily overlooked, to the medium, visible Cough, spitting, chest tightness and temporary chest pain, but also easily misdiagnosed as bronchitis; to be
