陶粒砂是由铝矾土与铁、锰、镁等金属添加剂经高温烧结而成的一种物质,用做油井填料。它的生产工艺简单,生产过程中有大量粉尘产生,损害工人身体健康,尤其对肺和呼吸道损伤严重。我们曾对某陶粒砂厂接尘工人进行肺功能测定分析,现报道如下。1 对象与方法1.1 选择陶粒砂粉尘接触工人60名为接尘组,其平均年龄26.4岁(9～79岁),平均接生工龄4.9年(0.5～8.5年),另选某厂行政后勤无粉尘接触史的工人72名为对照组,平均年龄29.5
Ceramsite sand is made of bauxite and iron, manganese, magnesium and other metal additives sintered at high temperature from a substance, used as oil well packing. Its production process is simple, there is a lot of dust in the production process, damage to the health of workers, especially severe lung and respiratory tract injuries. We have carried out on a ceramsite mill workers dust lung function analysis, are reported below. 1 objects and methods 1.1 selected ceramsite dust contact workers 60 were dust-exposure group, the average age of 26.4 years (9 to 79 years old), average delivery length of service 4.9 years (0.5 ~ 8.5 years), the other a factory administrative logistics 72 workers with dust exposure history as the control group with an average age of 29.5
