我厂自开工生产以来,珩磨加工发动机连杆(40钢)孔,抛光曲轴飞轮平面(3号灰铸铁)一直采用煤油作冷却液。煤油挥发性大,在加工过程中散发出难闻的臭味,不但污染车间空气,且对某些操作者的皮肤有刺激,尤其是操作时间较长以后,易引起慢性鼻炎、泪囊炎、气管炎和皮炎等症,严重地影响工人的身体健康,工作环境卫生也不好。多年来,车间工人师傅迫切要求采用新型珩磨液取代煤油,改善劳动条件,搞好文明生产。
Since the start of production, our factory honing the engine connecting rod (40 steel) hole, polishing crankshaft flywheel plane (No. 3 gray iron) has been using kerosene as coolant. Large volatile kerosene in the process of emitting an unpleasant odor, not only pollute the workshop air, and some operators of the skin irritation, especially after a longer operating time, easy to cause chronic rhinitis, dacryocystitis, Bronchitis and dermatitis embolism, seriously affecting the health of workers, work environment and health is not good. Over the years, the workshop workers urgently required the use of new honing fluids instead of kerosene to improve working conditions and improve civilized production.
