根据对重庆、成都市两个电池厂的拌粉、打电工段三次卫生学调查,对85名按触乙炔炭黑与锰粉混合粉尘工人进行体检,并拍照X线胸片,发现混合尘肺4例。对所取得的资料作了详细的报道和讨论。两个电池厂均由小电池厂合并而成,六十年代初新建厂房后扩大生产规模。现有职工共1840人,年产各种电池一亿七千万只。乙炔炭黑为热裂炭黑的一种,与锰粉、石墨、氯化铵及氯化锌等按配方比例拌和,作为电芯粉原料。生产工艺为手工及半机械化操作。原料库、拌粉及打电工段的粉尘浓度很高,配料为47.5～50mg
According to the three batches of powder and electricity workers in Chongqing and Chengdu, two batches of batches were polled and three batches of polluting workers were interviewed. Eighty-five acetylene black and manganese powder dust workers were examined and X-ray films were taken and mixed pneumoconiosis 4 example. The information obtained has been reported and discussed in detail. The two battery plants are merged by a small battery factory, the new plant in the early sixties to expand production scale. A total of 1840 employees, with an annual output of 170 million batteries. Acetylene black is a kind of thermal black which is mixed with manganese powder, graphite, ammonium chloride and zinc chloride according to the formula proportion, which is used as raw material of battery powder. Production process for the manual and semi-mechanized operation. Raw material storage, mixing powder and electricity section of the high concentration of dust, ingredients for the 47.5 ~ 50mg
